ClassNotFoundException when instantiating workflow

System

Hi,

I am trying to run a workflow (created in Workflow Modeler 1.0.1.0, published to TeamSite 6.7.2, on Windows), which includes a URLTask.

This URLTask uses a Java class that I have created, DummyTask. We did the following:

1. Place the JAR file in {iw-home}/local/config/lib/content_center/customer_src/lib.
2. Shut down the TeamSite Servlet Engine (the old WAR file does not get deleted without this step).
3. From {iw-home}/local/config/lib/content_center/customer_src, execute make_toolkit.ipl.
4. Restart the TeamSite Servlet Engine.

From the output from the make_toolkit script, I can see that my JAR file is included in {iw-home}/local/config/lib/content_center/customer_out/customer.tk.war.

However, the JAR file does not show up in {iw-home}/httpd/webapps/content_center/WEB-INF/lib, as I would expect. The JAR file does, however, show up in {iw-home}/httpd/webapps/iw-preview/WEB-INF/lib. Most importantly, my code is not executed when I instantiate the workflow. I can see from the logs that it throws a ClassNotFoundException because it cannot find my class.

Any insights?

Thanks,
Dhruva

You should not need to shut down the servlet engine to get this working. Try putting your class file in iw-home/local/config/lib/customer_src/src.

Thanks for your response--that seems to work, and will do for now. However, I don't know how the administrators are going to feel about having to move source code to the testing and production servers. Therefore I still need to resolve the original issue.

We have also tried using the clobber target, then rebuilding the toolkit, but that doesn't help either. Nor does manually copying the JAR file to {iw-home}/httpd/webapps/content_center/WEB-INF/lib and issuing the command "iwreset -a".

Anyone else know what I can try?

What you actually trying to say?

If you are running make_toolkit.ipl from customization/development area of content_center and it is giving the message "Build Success". Then the jar file should copied in customer_out and production area (httpd).
What is your .jar file name? if it's name is same what is it creating then might be the new jar do not updating.

I tried moving the source code to customer_src/src, and that worked for a while. I then resumed building a JAR file and copying that to customer_src/lib, and that worked as expected until yesterday.

Now, I run make_toolkit.ipl, and it reports that ran successfully. I have verified that the JAR files are updated (by looking at the timestamp), but it still executes the older version of my code. I still have to recycle the servlet engine in order for my changes to take effect.

Does anyone know why this occurs?

Hi,
Sometimes it happens that You run the make_toolkit.ipl and the report shows that it ran successfully.
Aactually it is not so.

Try to follow these:
1.)Empty the customer_out and the httpd folder but by taking the backup of both the directory.
2.)Now run the make_toolkit.ipl and check if it has been updated in customer_out and the httpd directory.

Let me know the outcome.

HTH.
