I am getting a java.lang.OutOfMemoryError: Java heap space and I am not sure how to avoid it. I am writing out to what I thought was basically a socket buffer. I think it is javax.servlet.jsp.JspWriter.
However, when I attempt to write very large HTML file, ~700,000 lines, I get a java.lang.OutOfMemoryError: Java heap space. I confused why the framework doesn't just flush to socket. (Marsha, Marsha, Marsha) Kidding aside, can I make it flush to socket rather just growing the buffer.
I am using JSF 1.1.
Note, I did try adding this web.xml:
<context-param>
<param-name>facelets.BUFFER_SIZE</param-name>
<param-value>500000</param-value>
</context-param>
It did not seem to change anything.
Here is my code sample:
<html>
<f:view>
<head>
<title>Test</title>
</head>
<body id="page_body"
<h:form id="form">
<%
String s;
for (int i = 0; i < rowCount; i++) {
s = data.get(i);
out.println(s);
//flush after on every thousandths row.
//if(i%1000==1)
// out.flush();
} // for loop
%>
</h:form>
</body>
</f:view>
</html>
Here is the exception I get:

BTW, BalusC, if your out there please help. No pressure, lol. You answer about half the JSF questions.
Grae
You can try using -Xmx to increase heap size.
For apache tomcat use i.e. export CATALINA_OPTS="-Xmx1024M"

I have upgraded the following technologies in my project
Icefaces 1.8 to 3.3
jsf 1.X to 2.0
Not able to find what is the exact root cause . Pleae do needful
Thanks in Advance.
I'm migrating our jsf project to Spring Webflow + JSF. We use ehcache to store information about chat and users data. Dpwb class(serialized) pulls data from the ehcache. As long the Dpwb class is serialized it should work, why it is looking for serializing ehcache which I can't do anything about it.

The exception indicates that one of the objects that WebFlow is trying to serialize has an instance variable (or contains another object with instance variable) of type net.sf.ehcache.Cache, which is not serializable. Note that it is not enough just to mark an object as java.io.Serializable, all of its serialized members must also be serializable.
This question describes a test that you can use to check whether something is really serializable (the instance variables must be populated for the test to be meaningful):
how to test in Java that a class implements Serializable correctly (not just is an instance of Serializable)
From your flow definition, it looks like com.emyed.whiteboard.controller.WhiteboardIdentifiers must be serializable because it is stored in the flow scope.
From what I can see, it doesn't look like the "Dpwb" class needs to be serializable because it is only stored in the view scope, which doesn't require serializability.
I have deployed my webapp but for some reason, some exceptions appear when trying to load files into server, I don't know why is this happening. Sometimes when I try to upload a file the rich:fileUpload doesn't upload the file, the progress bar of the component never gets filled and an exception like the following appears on Tomcat's log:

Any idea on what could be happening? Where can I start looking for fixing this on my app?
CHeers,
I was having the same stacktrace in my project. I can explain why this is happening and few ways to fix it.
So richfaces fileUpload component assumes that multipart request InputStream was not yet read from other places. But if you have in your application any filter that executes simple
request.getParameter(anyParamName) this forces multipart request to read full inputstream and put everything into request.getParts() collection.
When richfaces fileupload attempts to read something from inputstream it cannot do it because the stream cursor is at the end(this is in tomcat sources) and just returns -1; This causes richfaces to think that it can not read anything from the stream.
To fix this you can remove all filters that force multipart request to parse inputStream.
Also as a hot fix you can try to alter some of the richfaces classes like MultipartRequest25 or MultipartRequestParser.
I have added hot fix to MultipartRequestParser in order to check if request already has Parts and attempt to parse there parts into FileUploadParam. This is quite hacky checking the message of the exception but it can work as a hot fix.
There exists non resolved issue in jboss jira that seems to be about this issue. You can check it out. I was adding a comment there too. https://issues.jboss.org/browse/RF-13061
public void parse() throws FileUploadException {
try {
initialize();
while (!sequenceMatcher.isEOF()) {
readNext();
}
} catch (IOException e) {
if(e.getMessage().equals(REQUEST_PROLOG_CANNOT_BE_READ)){
//means it can not read request prolog. maybe application server already read everything and stores data in parts
try {
if(request.getParts()!=null && request.getParts().size()>0){
Collection<Part> parts = request.getParts();
//parts seem to be complete files so get the headers and so on here
//and create fileUploadItems from parts
for(Part part:parts){
String headersString = part.getHeader("content-disposition");
Multimap<String, String> headers = LinkedListMultimap.create();
String[] split = headersString.split("\r\n");
for (String headerString : split) {
parseParams(headerString, "; ", headers);
}
FileUploadParam param = createParam(headers);
if (param == null) {
continue;
}
param.create();
try{
int size = (int)part.getSize();
byte[] buf = new byte[size];
part.getInputStream().read(buf, 0, size);
param.handle(buf, size);
}finally{
param.complete();
}
if (param.isFileParam()) {
uploadedFiles.add(new UploadedFile25(param.getName(), param.getResource(), headers));
} else {
parametersMap.put(param.getName(), param.getValue());
}
}
//return from the method if everything was successfull
return;
}
} catch (Exception e1) {
this.cancel();
throw new IllegalStateException("Could get Parts from the request", e1);
}
}
this.cancel();
throw new FileUploadException(MessageFormat.format("Exception parsing multipart request: {0}", e.getMessage()), e);
}
}
Can i pass an expression as a method expression parameter like this ?
<p:dataTable id="gridRPBDetails" var="rpbDetail"
value="#{tInputBean.detailList}"
selection="#{tInputBean.selectedDetails}">
....
<p:commandButton
process="#this"
action="#{tInputBean.querySubAnggaranListImpl(rpbDetail.map['budget'])}" ... />
....
</p:datatable>
I tried this but ended with exception :

Here's my action method (please note that rpbDetail.map['budget'] is a type of DataTransferObject, so it should fit right in) :
public void querySubAnggaranListImpl(DataTransferObject budget) {
DebugUtil.start("querySubAnggaranListImpl");
String budgetId = budget.getString("id");
// cari subbudgetlist berdasarkan budgetId
this.comboChainSubAnggaranList = ch.execute("common", "GetSubBudgetList",
new DataTransferObject()
.putString("budgetId", budgetId))
.getList("result");
DebugUtil.end("querySubAnggaranListImpl");
}
I tried this out of deperation : action="#{tInputBean.querySubAnggaranListImpl(#{rpbDetail.map['budget']})}", and ended up with this error message on my browser :
/TInput.xhtml #161,40

check can be disabled by setting the
system property
org.apache.el.parser.SKIP_IDENTIFIER_CHECK
to true.
How can i pass the parameter to the method expression like my case above ?
Thank you !
I finally found out that this was my mistake. It should be
rpbDetail.map.subBudget.map.budget.
rpbDetail.map.budget returns null, hence the NullPointerException.
I try to run one program in myeclipse where after creating one web project I added JSF and ICEFaces capability in the program.
now after configuring Jboss web server when I start it I found following error.

Look like the faces configurator isn't initialized. Try adding the following entry to the web.xml:
<listener>
<listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>
