Subject: URLGetMethod.executeMethod is hanging under multi threaded environment

Hello Guys,

Please see the folloiwng code. I am trying to download the mails of MS Exchange Server using
URLGetMethod.executeMethod( A Part of Slide API). But when execution pointer comes to the thread area
(URLGetMethod.executemethod),

URLGetMethod.executemethod is not coming out of it's loop. Could you please explain what is the
problem with this code??

class SaveAttachmentThread
extends Thread
implements Runnable {
static int threadCount = 0;
String uri = "";
String strAttachmentName = "";
private org.apache.commons.httpclient.HttpClient client = null;
org.apache.commons.httpclient.methods.UrlGetMethod attachmentMethod = null;

public SaveAttachmentThread(String uri, String strAttachmentName,
org.apache.commons.httpclient.HttpClient client) {
this.uri = uri;
this.strAttachmentName = strAttachmentName;
this.client = client;

}

public SaveAttachmentThread(org.apache.commons.httpclient.methods.
UrlGetMethod _getMethod, String attachment) {
attachmentMethod = _getMethod;
this.strAttachmentName = attachment;
}

public void run() {
//strAttachmentName = URLDecoder.decode(strAttachmentName);
System.err.println("Saved to " + strAttachmentName);
System.err.println("URL :" + uri);
try {

System.err.println("Saving the URL :" + strAttachmentName);
org.apache.commons.httpclient.methods.UrlGetMethod getMethod = new org.
apache.commons.httpclient.methods.UrlGetMethod(uri);
int status = client.executeMethod(getMethod);

byte attachmentBytes[] = getMethod.getResponseBody();
FileOutputStream fout = new FileOutputStream(strAttachmentName);
fout.write(attachmentBytes);
fout.close();
fout = null;

threadCount++;
System.err.println(threadCount);

}
catch (Throwable e) {
System.err.println("Error raised while saving the URI : " +
strAttachmentName);
e.printStackTrace();
}
}
}

dump the state of the threads to determine cause of block.

How should I do that??

Mick Barry

Ctrl Break

ASKER

:-)

I have already done that. It's not showing anything

CEHJ

Might be worth setting the timeout and then handling possible exceptions

Mick Barry

> It's not showing anything

Must show something :)

when i use Ctrl Break

It just teminates the entire program

Mick Barry

Shouldn't do, what OS?

Not related to you problem, but you don't actually need to extend Thread here.
You can simply create a thread from a Runnable.

OK objects,

I am able to manage to get the stack trace

Here is the output what I get from the stack

If you do this. it'll make that debugging a whole lot easier:

thread.setName("Url thread: " + urlToGet);

I did not realise that. I thought that was smaller :(

By chance , Is any thread locked??

Mayank S

>> extends Thread
>> implements Runnable {

Why do you have both?

sudhakar_koundinya

ASKER

will that give any problem??. Let me check that

sudhakar_koundinya

ASKER

No Sridhar,

Even if I just use extends thread or Implements runnable. The problem is same.

Mayank S

The problem could be there. I pointed that out not as something relevant to this question but as basic Java programming practice/ concepts. You should not need to do both.

CEHJ

>>what does that mean??

It's not relevant. Nor is the interface/extends issue. What you most probably have is a blocked read in one of the threads, which is perfectly usual, so you should treat it as i mentioned earlier

Mayank S

>> The problem could be there.

I meant it could NOT be there ;) but I pointed it out as....

Mick Barry

Perhaps the problem is with the server, I'd suggest having a look at what it's doing.
May be that it has locked up processing lots of concurrent connections.

The actual code to create HttpClient instance
if (manager == null) {
manager = new MultiThreadedHttpConnectionManager();
manager.setMaxTotalConnections(30);
manager.setMaxConnectionsPerHost(10);
}
client = new HttpClient(manager);
// client = new HttpClient(); ---> this is actual in WebDavResouce class

> objects I am able to solve the problem.

good work :)
