I have another question about a "JDWP Error: 21" logged: Unexpected JDWP Error 21
I am trying to parse some XML I gather from a servlet into a J2ME MIDlet with the code below. So far unsuccessfully, I think due to the JDWP error on my HttpConnection how ever the InputStream is filled with XML and once parsed everything inside the Document is null.
Has anyone got and ideas about the JDWP error, and also does that code look like it should work?
In MIDlet I am using JSR-172 API javax.xml.parsers.*.
if(d==form1 && c==okCommand)
{
// Display Webpage
webPage = new TextBox(txtField.getString(),
"",
100000,
TextField.ANY
);
Display.getDisplay(this).setCurrent(webPage);
try
{
HttpConnection conn = (HttpConnection)Connector.open("http://localhost:8080/Blogging_Home/Interface?Page=Bloggers&Action=VIEW&Type=XML");
conn.setRequestMethod(HttpConnection.GET);
int rc = conn.getResponseCode();
getConnectionInformation(conn, webPage);
webPage.setString(webPage.getString() + "Starting....");
String methodString = getStringFromURL("");
if (rc == HttpConnection.HTTP_OK)
{
InputStream is = null;
is = createInputStream(methodString);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
Document document;
try
{
builder = factory.newDocumentBuilder();
document = builder.parse(is);
} catch (Exception e) {
e.printStackTrace();
}
}
else
{
webPage.setString(webPage.getString() + "ERROR:" + rc);
}
}
catch(Exception ex)
{
// Handle here
webPage.setString("Error" + ex.toString());
}

Hello im trying to output an excel file generated from a template xls using jxls library but I dont find the way to do so.
My code look like this:
ServletContext contexto = request.getServletContext();
String path = contexto.getRealPath("/lib/xlsx/plantilla.xlsx");
Conexion conexion = new Conexion();
List<Conexion> conexiones = new ArrayList<Conexion>();
ResultSet rs = CargarConsultas.ejecutarConsulta("CONS_GET_TABLA_CONEXION");
try {
while(rs.next()) {
conexion.setIp(rs.getString("ori_ip"));
conexion.setMac(rs.getString("ori_mac"));
conexion.setUrl_destino(rs.getString("url_dest"));
conexion.setSolicitud(rs.getString("time_stamp_solicitud"));
conexion.setUser_id(rs.getString("user_id"));
conexion.setSubida(rs.getString("icoming"));
conexion.setBajada(rs.getString("outgoing"));
conexion.setAutorizacion(rs.getString("time_stamp_autorizacion"));
conexion.setRenovacion(rs.getString("time_stamp_renovacion"));
conexion.setFin_sesion(rs.getString("time_stamp_fin_sesion"));
conexion.setGw_adress(rs.getString("gw_address"));
conexion.setGw_port(rs.getString("gw_port"));
conexiones.add(conexion);
}
} catch (SQLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
File salida = new File(path);
InputStream is = new FileInputStream(salida);
try (FileOutputStream os = new FileOutputStream("salida.xlsx")) {
Context context = new Context();
context.putVar("conexiones", conexiones);
JxlsHelper.getInstance().processTemplate(is, os, context);
} catch (Exception e) {
e.printStackTrace();
}
Please let me knoew if you know how to output it and no save it to server disk.The code works fine. Thanks alot

Please check,

check it and try:

((EntityReference)targetEntity["new_outboundcallid"]).Id
member["new_ringkasanlejarid"] = targetEntity.Attributes["incidentid"].ToString();
What is new_ringkasanlejarid's type? You're setting a string to it. If new_ringkasanlejarid is an entity reference, this might be causing problems.
You might want to share the error details or trace log, all we can do is assume what the problem is at the moment.
I am trying to download image from Internet using async call like this:
private void DoGetAlbumart(object sender, DoWorkEventArgs e)
{
string req = (string)e.Argument;
WebClient wc = new WebClient();
wc.OpenReadCompleted += new OpenReadCompletedEventHandler(ReadWebRequestCallback);
wc.OpenReadAsync(new Uri(req));
}
void ReadWebRequestCallback( object sender, OpenReadCompletedEventArgs e)
{
if (e.Error == null && !e.Cancelled)
{
try
{
BitmapImage image = new BitmapImage();
image.SetSource(e.Result);
SecondTile.Source = image;
}
catch (Exception ex)
{
}
}
else
{
}
}
It seems that when breakpoint hits at BitmapImage image = new BitmapImage(), I got the following exception:
ex = {System.UnauthorizedAccessException: Invalid cross-thread access.
at MS.Internal.XcpImports.CheckThread()
at System.Windows.DependencyObject..ctor(UInt32 nativeTypeIndex, IntPtr constructDO)
at System.Windows.Media.Imaging.BitmapImage..ctor()
What else can I try to get rid of this error?
Callback methods run in background threads, not the UI thread. Unfortunately, BitmapImages can only be instantiated in the UI thread. If you need to access the UI thread from a callback, try the following:
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
BitmapImage image = new BitmapImage();
image.SetSource(e.Result);
SecondTile.Source = image;
});
I have problems reading from my MSMQ. When I write to the queue, it works perfectly, but when I try to read that message from the queue, I get the following exception: "The queue does not exist or you do not have sufficient permissions to perform the operation." The queue does exists, and I have full permissions on the machine and queue. Here is my code:
public string path = #".\private$\";
public void WriteToQueue(string QueueName, object messageObject)
{
try
{
path = path + QueueName;
MessageQueue msmq = null;
if (!MessageQueue.Exists(path))
{
msmq = MessageQueue.Create(path);
}
else
{
msmq = new MessageQueue(path);
}
msmq.Formatter = new XmlMessageFormatter(new Type[] { typeof(string)});
msmq.Send(messageObject);
msmq.Close();
}
catch (MessageQueueException ex)
{
System.ArgumentException argEx = neArgumentException(ex.ToString());
throw argEx;
}
path = #".\private$\";
}
public string ReadQueue(string QueueName)
{
try
{
path = path + QueueName;
MessageQueue msmq = new MessageQueue(path);
string msg;
msmq.Formatter = new XmlMessageFormatter(new Type[] { typeof(string)});
msg = msmq.Receive().Body.ToString(); //exception is thrown here
path = #".\private$\";
return msg;
}
catch (Exception ex)
{
return null;
}
}
can the problem maybe be with reading it as type of string? Maybe not in the right format?
Try this:
public string path = ".\\private$\\";
'#' doesn't work for me too.
I have the following code in groovy
HTTPBuilder http = new HTTPBuilder("https://ronna-afghan.harmonieweb.org/_layouts/searchrss.aspx")
http.request(Method.GET, groovyx.net.http.ContentType.XML) {
// set username and password for basic authentication
// set username and password for basic auth
//http.auth.basic(ConfigurationHolder.config.passportService.userName,
// ConfigurationHolder.config.passportService.password)
headers.'User-Agent' = 'Mozilla/5.0'
uri.query = [k:'execution']
// response handler for a success response code:
response.success = {resp, xml ->
println resp.statusLine
log.debug "response status: ${resp.statusLine}"
log.debug xml.toString()
}
// handler for any failure status code:
response.failure = {resp ->
log.error " ${resp.statusLine.statusCode} : ${resp.statusLine.reasonPhrase}"
}
}
when I run the code, it doesn't give me the rss feed which I'm suppose to get
When I have the same code in java
try {
// Create a URLConnection object for a URL
URL oracle = new URL(
"https://ronna-afghan.harmonieweb.org/_layouts/srchrss.aspx?k=execution&count=1&format=rss");
URLConnection yc = oracle.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
yc.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) {
System.out.println(inputLine);
in.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}
it returns the xml Rss. I can't figure what the issue might be. Everything looks okay to me in the groovy code and also the Http return code is 200.
The code that you have described in Java is the equivalent of the following code in Groovy:
def oracle = "https://ronna-afghan.harmonieweb.org/_layouts/srchrss.aspx?k=execution&count=1&format=rss".toURL().text
