I want to edit my question.
If file still not exist, download and save it, that my case.
To check if file exist, I've try by this code
private boolean isXmlFileExist(){
try{
FileConnection fCon = (FileConnection) Connector.open("file:///"+Resource.XML_PATH + "/" + Resource.XML_FILENAME, Connector.READ);
return fCon.exists();
}catch (Exception e) {
e.printStackTrace();
return false;
}
}
In my resource class
public static final String XML_PATH = "/xml";
public static final String XML_FILENAME = "template.xml";
I have create 'xml' folder under res folder and i have put file 'template.xml' there. But this code always return false.
Whether we can not use the res folder? So, what is the correct path.
Files under res folder are always available because they are packaged with the class files. So, you do not need to check with FileConnection if they exist.
To access these files you can use Class.getResourceAsStream.
For example:
private InputStream open (String fileName) {
return getClass().getResourceAsStream(fileName);
}
// call it like this
open(Resource.XML_PATH + "/" + Resource.XML_FILENAME);

i am writing my own image import for my product catalog. I want to read the images from the local filesystem and store them in the configured assets folder. The import is very simple for now. Its one controller in the admin project and i trigger it by calling an url.
It is creating the files along with the folder structure and the files seem to have the same filesize, but somehow they get messed up along the way and they are not readable as images anymore (picture viewers wont open them). Any ideas why its being messed up ?
here the code:
#Controller("blImageImportController")
#RequestMapping("/imageimport")
public class ImageImportController extends AdminAbstractController {
#Value("${image.import.folder.location}")
private String importFolderLocation;
#Resource(name = "blStaticAssetService")
protected StaticAssetService staticAssetService;
#Resource(name = "blStaticAssetStorageService")
protected StaticAssetStorageService staticAssetStorageService;
#RequestMapping(method = {RequestMethod.GET})
public String chooseMediaForMapKey(HttpServletRequest request,
HttpServletResponse response,
Model model
) throws Exception {
File imageImportFolder = new File(importFolderLocation);
if (imageImportFolder.isDirectory()) {
Arrays.stream(imageImportFolder.listFiles()).forEach(directory ->
{
if (directory.isDirectory()) {
Arrays.stream(directory.listFiles()).forEach(this::processFile);
}
});
}
return "";
}
private void processFile(File file) {
FileInputStream fis = null;
try {
HashMap properties = new HashMap();
properties.put("entityType", "product");
properties.put("entityId", file.getParentFile().getName());
fis = new FileInputStream(file);
StaticAsset staticAsset = this.staticAssetService.createStaticAsset(fis, file.getName(), file.length(), properties);
this.staticAssetStorageService.createStaticAssetStorage(fis, staticAsset);
fis.close();
} catch (Exception e) {
} finally {
try {
if (fis != null)
fis.close();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
}
There is a check in the StaticAssetService to try to detect this as an image (see https://github.com/BroadleafCommerce/BroadleafCommerce/blob/b55848f/admin/broadleaf-contentmanagement-module/src/main/java/org/broadleafcommerce/cms/file/service/StaticAssetServiceImpl.java#L217-L220). If it detected this correctly, you should get back an ImageStaticAssetImpl in the result to that call.
The flipside of this is the controller that actually reads the file (the StaticAssetViewController that renders a StaticAssetView). One of the things that the StaticAssetView does is set a response header for mimeType which the browser uses to render. This is set by this piece in the StaticAssetStorageService: https://github.com/BroadleafCommerce/BroadleafCommerce/blob/b55848f837f26022a620f0c2c143eed7902ba3f1/admin/broadleaf-contentmanagement-module/src/main/java/org/broadleafcommerce/cms/file/service/StaticAssetStorageServiceImpl.java#L213. I suspect that is the root of your problem.
Also just a note, sending those properties is not necessary when you are uploading the file yourself. That is mainly used in the admin when you are uploading an image for a specific entity (like a product or a category).
Can someone explain how I debug this?
I have built a windows service which monitors a folder and when a file is created in that folder, it moves that newly created file to another folder. Pretty simple and works. I am trying to pad it out now with out features and I'm starting to get generic IOExpections thrown in event viewer, so I want to try and debug. But the issue I am having is when to create the new file in the directory during debugging.
This is my code so far
which line should I stop at during stepping through, place my new file in the directory and then continue debugging so that it picks up the created file?
public void OnDebug()
{
OnStart(null);
}
[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
protected override void OnStart(string[] args)
{
string pathToWatch = ConfigurationManager.AppSettings["DirectoryToWatch"];
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.Path = pathToWatch;
watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.FileName;
watcher.Created += new FileSystemEventHandler(FileCreated);
watcher.EnableRaisingEvents = true;
}
private void FileCreated(object source, FileSystemEventArgs e)
{
try
{
DateTime dt = File.GetCreationTime(e.FullPath);
File.Move(e.FullPath.ToString(), ConfigurationManager.AppSettings["DirectoryToMoveTo"] + e.Name + dt.ToString());
LogEvent($"New file found and moved \n {e.FullPath.ToString()}");
}
catch (IOException ex)
{
LogEvent(ex.ToString());
}
}
You can start by adding a breakpoint inside the function FileCreated.
I suggest you add a breakpoint at
DateTime dt = File.GetCreationTime(e.FullPath);
When you create a new file in the directory being watched, the FileSystemWatcher gets notified and the function FileCreated is called.
I also suggest you to log the destination path for your move. Just to make sure it's a valid path.

How to get properties file from /WEB-INF folder in JSF?
(3 answers)
Closed 7 years ago.
I'm developing a web application(this is my first time) and pretty confused about using property files. I don't know where to put the property files.
The problem is that i have put it under the WEB_INF folder. And when i test run it as a Java Application to check whether Database connections are working according to the properties in the property file it is working without any problem.
But when i run it in a Server as a Web Application it fails to load the properties file saying it could not find the file in the path specified. I tried using every possible path i could give and changing the file directories within the whole project. But I kept getting the same error.
Then i changed my class again from scratch thinking there's some kind of a bug withing my code where i load the properties file. And it seems that it could not find the file either when deployed as a Web App. But my test application works fine. Where do i put this file and how do i use it. I have read #BalusC's answer in this thread https://stackoverflow.com/a/2161583/2999358 but i have no idea why this happens. Can someone help me on this?
I'm using Tomcat 8, Eclipse IDE and building on JSF framework.
Class where i load my properties file
public class ConfigCache {
private static final File FILE = new File("./WebContent/WEB-INF/conf/config.properties");
private static final Properties PROPERTIES = new Properties();
public static final String JDBC_DRIVER = ConfigCache.getProperty("db.driverName");
public static final String DATABASE_URL = ConfigCache.getProperty("db.url");
public static final String DATABASE_USERNAME = ConfigCache.getProperty("db.user");
public static final String DATABASE_PASSWORD = ConfigCache.getProperty("db.pass");
public ConfigCache() {
}
public static String getProperty(String key) {
if (PROPERTIES.isEmpty()) {
loadProperties();
}
Object value;
return (value = PROPERTIES.get(key)) == null ? "" : value.toString();
}
private static void loadProperties() {
if (!FILE.exists()) {
throw new IllegalArgumentException("The 'config.properties' has not been found.");
}
try {
FileInputStream fis = null;
try {
fis = new FileInputStream(FILE);
PROPERTIES.load(fis);
} finally {
try {
if (fis != null) {
fis.close();
}
} catch (IOException exp) {
System.out.println("IOException #" + ConfigCache.class + " # loadProperties() : " + exp);
}
}
} catch (Exception exp) {
System.out.println("Exception #" + ConfigCache.class + " # loadProperties() : " + exp);
}
}
}
Folder Structure
Try With this.
put the property in src folder.
Your file is in the WEB-INF directory. This means it's part of the war and reachable as part of the class path. That's perfectly ok, since it makes it portable and independant of the web container installation (e.g. Tomcat).
You can load any file in the class path as a resource:
getClass().getResourceAsStream("/conf/config.properties")
This means you can write your code like this:
private static void loadProperties() {
InputStream is = getClass().getResourceAsStream("/conf/config.properties");
PROPERTIES.load(fis);
}
(Error handling omitted)
You can explode (unzip) your war/ear file and see the contents or folder structure of it and find why your code doesnt work. The reason is that the folder WebContent doesnt exist in your ear/war , but does exist only when run via eclipse. This is the reason why its always better to follow the solution provided in the link posted so that you can retrieve the porperty files from classpath. The below code fetches your property file in eclipse but not in the server.
private static final File FILE = new File("./WebContent/WEB-INF/conf/config.properties");
Contents of WAR file (from JournelDev), it contains WEB-INF directory but there would be no WebContent directory above it
I'm using Wicket (not sure if it matters) but I'm using Workbook to create an excel file for a user to download. But I'm not sure how exactly to do this. What I would like to happen is the user clicks the button, a log is created and a prompt is given to the user to open (and save to temp files) or to save to their computer. The file is then deleted from the server side, or maybe it is stored in the User's session and deleted at end of session.
Can someone point me in the right direction? If I can have the file not saved in the session at all, that'd be create and have it just have it sent to the client using FileOutputStream somehow..
here is my current code:
private void excelCreator()
{
Workbook workbook = new HSSFWorkbook();
Sheet sheet = workbook.createSheet(WorkbookUtil.createSafeSheetName("SSA User ID " + currentSSAIDSelection2.getSsaUserId()));
Iterator<AuditLogEntry> auditLogEntrys = logList.iterator();
int i = 0;
while (auditLogEntrys.hasNext())
{
final AuditLogEntry auditLogEntry = auditLogEntrys.next();
Row row = sheet.createRow(i);
row.createCell(0).setCellValue(auditLogEntry.getTimeStamp());
row.createCell(1).setCellValue(auditLogEntry.getSourceName());
row.createCell(2).setCellValue(auditLogEntry.getCategory());
row.createCell(3).setCellValue(auditLogEntry.getSsaAdmin());
row.createCell(4).setCellValue(auditLogEntry.getAction());
i++;
}
try
{
FileOutputStream output = new FileOutputStream("ssaUserIDAccess.xls");
workbook.write(output);
output.close();
}catch(Exception e)
{
e.printStackTrace();
}
}
You would have to create a DownloadLink with the temporary file as input. The temporary File must be deleted after download (file.delete())).
Alternatively you can try this:
IResourceStream stream = new ByteArrayResourceStream(data, "application/vnd.ms-excel");
RequestCycle.get().scheduleRequestHandlerAfterCurrent(new ResourceStreamRequestHandler(stream, filename).setContentDisposition(ContentDisposition.ATTACHMENT));
In this case data is the byte[] content of your workbook which can be for example retrieved with output.toByteArray().
In case anyone runs into this problem here is my solution. There wasn't a lot of straight forward answers on this but this is my solution:
My excelCreator method handles the creation of the excel Sheet, and returns it as a file.
private File excelCreator()
{
Workbook workbook = new HSSFWorkbook();
File excelfile = new File("userIDAccess.xls");
logList = getServer().findAuditLogs(getUserId(), null);
Sheet sheet = workbook.createSheet(WorkbookUtil.createSafeSheetName("User ID " + getUserId()));
Iterator<AuditLogEntry> auditLogEntrys = logList.iterator();
int i = 0;
while (auditLogEntrys.hasNext())
{
final AuditLogEntry auditLogEntry = auditLogEntrys.next();
Row row = sheet.createRow(i);
row.createCell(0).setCellValue(auditLogEntry.getTimeStamp());
row.createCell(1).setCellValue(auditLogEntry.getSourceName());
row.createCell(2).setCellValue(auditLogEntry.getCategory());
row.createCell(3).setCellValue(auditLogEntry.getSsaAdmin());
row.createCell(4).setCellValue(auditLogEntry.getAction());
i++;
}
try
{
FileOutputStream output = new FileOutputStream(excelfile);
workbook.write(output);
output.close();
}catch(Exception e)
{
e.printStackTrace();
}
return excelfile;
}
IModel excelFileModel = new AbstractReadOnlyModel()
{
public Object getObject()
{
return excelCreator();
}
};
I created an IModel to capture the file created inside my excelCreator() method and returned.
auditDownloadlink = new DownloadLink("auditDownloadlink", excelFileModel);
I pass the I.D. of the download link, and then pass the imodel.
finally,
I call,
auditDownloadlink.setDeleteAfterDownload(true);
auditDownloadlink.setCacheDuration(Duration.NONE);
This deletes the file after it is created. And the cache setting is a setting to make sure it is compatible with all browsers (That's how I interpreted it, but you may not need it).
The Imodel creates the File on the fly so it doesn't have to be stored anywhere, and then the file is deleted once it is downloaded.
Hope this helps someone!
You could create a Resource to do this, and make a ResourceLink.
public class ExcelProducerResource extends AbstractResource
{
public ExcelProducerResource()
{
}
#Override
protected ResourceResponse newResourceResponse( Attributes attributes )
{
final String fileName = getFileName();
ResourceResponse resourceResponse = new ResourceResponse();
resourceResponse.setContentType( "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" );
resourceResponse.setCacheDuration( Duration.NONE );
resourceResponse.setFileName( fileName );
resourceResponse.setWriteCallback( new WriteCallback()
{
#Override
public void writeData( Attributes attributes ) throws IOException
{
OutputStream outputStream = attributes.getResponse().getOutputStream();
writeToStream( outputStream );
outputStream.close();
}
} );
return resourceResponse;
}
void writeToStream(OutputStream outputStream) throws IOException
{
//.. do stuff here :)
}
String getFileName()
{
//.. do stuff here :)
}
}
I've put together a function that creates a sharepoint folder in a document library based on the url that's past in as an argument. The code works and the folder shows up in sharepoint from the webapplication.
However, when I query the SPWeb object for the folder afterward, it says the folder doesnt exist. Which makes no sense to me. Stranger still, is that this very same code worked no too long ago. I had been using it to create tree structures in sharepoint.
Even if the query folder fails, the GetFolder still returns a the folder, but when I add files to the returned folder, I get a runtime exception indicating that the file doesn't exist...which I assume means the folder I am trying to add it to doesn't exist since the file I am adding, doesn't exist yet. Which is why I am adding it.
So my question is, why am I getting this error, and why does FolderExists return false when the folder actually exists? We know it exists because GetFolder actually returns it...
I've included some actual code from the app to make things clear.
If someone could have a look at the code and see and anything jumps out at them, that would be fantabulous...Thanks
Code to build folders:
public void CreateFolder(SPUriBuilder url)
{
try
{
Log.Instance.WriteToLog("CreateFolder({0})", url);
var library = GetLibrary(url.Library);
if (library != null)
{
// parse out string data
//
var parent = library.RootFolder.ServerRelativeUrl;
var segments = url.Account.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries);
var path = parent;
// get default folder collection
//
SPFolderCollection subFolders = _web.GetFolder(parent).SubFolders;
// check for sub-folders to create
//
if (segments.Length > 0)
{
int i = 0;
do
{
// check for folder and create if non-existant
//
var buildPath = String.Format("{0}/{1}", path, segments[i]);
if (_web.GetFolder(buildPath).Exists == false)
_web.GetFolder(path).SubFolders.Add(segments[i]);
// retrieve new sub-folder collection
//
subFolders = _web.GetFolder(buildPath).SubFolders;
path = buildPath;
// next folder in path
//
i++;
}
while (i < segments.Length);
}
// finally, add folder of interest
//
subFolders.Add(url.Folder);
}
}
catch (Exception e)
{
throw new SPImportException("Exception: {0}, creating folder: {1} in Library: {2}", e.Message, url.Folder, url.Library);
}
}
Code to Query folder:
public bool FolderExists(SPUriBuilder url)
{
return _web.GetFolder(url.Uri.LocalPath).Exists;
}
Code to Get Folder:
private SPFolder GetFolder(SPUriBuilder url)
{
return _web.GetFolder(url.Uri.LocalPath);
}
The SPUriBuilder is a custom class I created to assemble the Uri:
public class SPUriBuilder
{
public string SiteUrl { get; private set; }
public string Library { get; private set; }
public string Parent { get; private set; }
public string Folder { get; private set; }
public string File { get; private set; }
public string Account { get; private set; }
public Uri Uri { get; private set; }
public SPUriBuilder(string siteUrl, string library, string account, string parent, string folder)
{
this.SiteUrl = siteUrl;
this.Library = library;
this.Account = account;
this.Parent = parent.Replace("\\", "/");
this.Parent = this.Parent.StartsWith("/") ? this.Parent.Substring(1) : this.Parent;
this.Folder = folder;
StringBuilder url = new StringBuilder();
url.AppendFormat("{0}/{1}/{2}", SiteUrl, Library, Account);
if (String.IsNullOrEmpty(Parent) == false)
url.AppendFormat("/{0}", Parent);
url.AppendFormat("/{0}", Folder);
this.Uri = new Uri(url.ToString());
}
public SPUriBuilder(SPUriBuilder uri, string file)
: this(uri.SiteUrl, uri.Library, uri.Account, uri.Parent, uri.Folder)
{
this.File = file;
StringBuilder url = new StringBuilder();
url.AppendFormat("{0}/{1}", this.Uri.ToString(), this.File);
this.Uri = new Uri(url.ToString());
}
public override string ToString()
{
return Uri.ToString();
}
}
I found the answer this to this myself. The problem was in the code used to create the folder.
var parent = library.RootFolder.ServerRelativeUrl;
// This line of code is incorrect, so it returned the wrong data, thus building the folder path incorrectly.
//
var segments = url.Account.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries);
var path = parent;
// This is the replacement line of code that fixed the issue.
//
var segments = url.Uri.LocalPath.Substring(parent.Length+1).Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries);
// as well, this line had to be removed since it was no longer needed
//
// finally, add folder of interest
//
subFolders.Add(url.Folder);
Ultimately the issue turned out be that the folder structure did not exist that I was attempting to create the file in. One or more segments in the path were missing.
So if you ever see this error, make sure you're the folder exists that you are adding the file to. If it isn't, you will certainly experience this error.
