Calling JAVA class in URLexternal task

Hi Alll,

I have copied "URLExternalTaskTest.java" Which is come along with TeamSite and present at location

/iw-home/local/config/lib/content_center/customer_samples_src/src/com/corp/custom

And pasted it at loaction

/iw-home/local/config/lib/content_center/customer_src/src/com/corp/custom

And ran "make_toolkit.ipl" from
/opt/teamsite/iw-home/local/config/lib/content_center/customer_src/
loaction

Built was successful

And I made workflow just simple having start-> URL TAsk -> end Task (attaches ipm file)

Variable set to ClassName=com.corp.custom.URLExternalTaskTest
URI set to http://$IW_SERVER/iw-cc/urlexternaltask

But workflow is not going to next(end task)

And "servletd_out.log" is getting updated when running WF with below entry(I confirmed it is just warning not error "Workflow should work" even with this warrning)

2010-07-06 07:21:25,898 [http-8080-Processor23] WARN com.interwoven.ui.datacapture.core.dcxp.DTDNodeOrderingStrategy (sumit.k.katre) - Error reading DTD http://localhost/iw-cc/datacapture6.0.dtd. Message: At line 2, column 3: Unexpected token: LT(null)

Note: here attachements having ".txt" extension just to uploading on devnet purpose on server they are having ".ipm" and ".java" extensions

Thanks in advance

Sample java code which came along with teamsite is as below
"This sample java code also not working in URLexternal task" It is not writing any thing in serveletd_out.log file

/*
* URLExternalTaskSimpleTest.java
*/

package com.corp.custom;

import com.interwoven.cssdk.common.CSClient;
import com.interwoven.cssdk.common.CSException;
import com.interwoven.cssdk.workflow.CSExternalTask;
import com.interwoven.cssdk.workflow.CSTask;
import com.interwoven.cssdk.workflow.CSURLExternalTask;
import com.interwoven.cssdk.workflow.CSWorkflow;
import com.interwoven.log100.Logger;
import com.interwoven.log100.LoggerFactory;

import java.util.Hashtable;

/**
* An simple implementation of an external task.
*/
public class URLExternalTaskTest
implements CSURLExternalTask
{
// Define a LOGGER for debugging purpose
private static final Logger LOGGER = LoggerFactory.getLogger(URLExternalTaskTest.class.getName());

/**
* An example of an implementation of ExternalTask. It iterates MAX_ITERATIONS times of usertask
* and then end the workflow.
*/
public void execute ( CSClient client, CSExternalTask task, Hashtable params)
throws CSException
{
int max_iterations = Integer.parseInt(task.getVariable("MAX_ITERATIONS"));
if (LOGGER.isDebugEnabled()) {
LOGGER.debug("max_iterations = " + max_iterations);
}
int iteration = task.getVariable("ITERATION") == null ? 0 :
Integer.parseInt(task.getVariable("ITERATION"));
int transition = ((iteration < max_iterations) ? 1 : 0);
task.setVariable("ITERATION", String.valueOf(++iteration));
CSWorkflow job = task.getWorkflow();
CSTask[] tasks = job.getTasks();
for (int i = 0; i < tasks.length; i++) {
if ("Wait for next test".equals(tasks.getName())) {
tasks.setDescription("Iteration " + iteration + " of " + max_iterations);
break;
}
}
task.chooseTransition(task.getTransitions()[transition], "");
}
}

Do you have a MAX_ITERATIONS task variable on your External Task?
Do you have a task named "Wait for next test" in your WFM?
Have you made any attempt to actually understand the code you are using and the context in which it is supposed to be run?

try this basic execute method.

public void execute ( CSClient client, CSExternalTask task, Hashtable params)
throws CSException
{
System.out.println("hello world");
task.chooseTransition("","");
}

This should print out hello world in your servletd_out log file and your workflow should transition to the next task or end depending on how your workflow is setup.

...
task.chooseTransition("","");
...

While the above might work (if you only have one transition from the External Task, or you're willing to accept it always choosing the first transition found) - it would be far better to ensure that you put the proper transition description string in the first argument. It's also generally a good idea to include at least some transition comment string in the second argument.
