Servlet Issue class not found?

I go through all the motions but when I try can call my servlet. I get this:

java.lang.ClassNotFoundException: com.company.teamsite.samples.HelloWorldExample
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1387)
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1233)

...but when I try [to] call my servlet I get this...

What exactly does that mean? How did you "map" the servlet to the TS "Action"? How do you call an Action?

Where does your servlet live?
did you add it to web.xml?
did you run maketool_kit.ipl?
How are you calling it?
you need to tell us all what you have done before you tried to call your servlet in case of you have missed something.

Since this post I have created an even more simplified servlet to rule out any coding errors.

Forgive me but I am just starting out with CCSDK etc.. transitioning from CGI/Perl development. I have attempted to add a custom servlet for some custom screen development. For now I'm just trying to get a basic servlet running which generates a simple html response.

I've created a "Project" folder here

/iw-home/local/config/lib/content_center/customer_src/web/expProject

In this directory I have the following structure.

/assets
/jsp
/META-INF
/WEB-INF
/WEB-INF/classes/com/company/teamsite/samples/ExampleServlet.class
/WEB-INF/web.xml
index.jsp

I have defined everything in the web.xml and the web.xml in the /iw-home/local/config/lib/content_center/customer_src/etc/web.xml

I have also run the /Interwoven/TeamSite/bin/make_toolkit.ipl script.

When I restart the UI and request the servlet http://serverName/iw-cc/ExampleServlet I get the above error which is a 500 error. When I refresh I get a 404.

I have gone through the UI customization guide and cant seem to figure out where I've gone wrong? Do I have to put my class files in a different location?

I still don't quite get the underlying structure but I tried placing my .java files in /iw-home/local/config/lib/content_center/customer_src/src and then ran the make_toolkit.ipl. My servlet is now working.

So, my issue is solved but what are the rules of thumb when extending the UI using custom JAVA, jsp's, servlets etc.

Is it that jsps images etc can live in your web/project folder but any java code needs to be in customer_src/src?

If you are just trying the water with the "Hello World", do the following (and nothing but!) first.
When that works you should be able to expand on it.

1. Create Servlet Source Folder /iw-home/local/config/lib/content_center/customer_src/src/com/ArbitraryName/custom

- "ArbitraryName" here is normally your Project Name or Company Name, stuff like that.
- Place your Servlet Java Code (Source Code) here. For this example sake I'll name it "hello_servlet.java"
I'll need this naming later on to illustrate mapping

2. Create JSP Source Folder /iw-home/local/config/lib/content_center/customer_src/web/YetAnotherArbitraryName

- Note that "YetAnotherArbitraryName" will be visible in URLs. You can make it identical to the first one - or not.
- Place JSP Source that calls "hello" Servlet here. Let's say it is "call_hello.jsp" Somewhere in it you'll use
a variant of <jsp:include page="/YetAnotherArbitraryName/greet_the_world" flush="true"/> Tag.
- "greet_the_world" here is so called TS Application "Command", we'll get to mapping in the moment

3. Map it all!

- Get to the Folder /iw-home/local/config/lib/content_center/customer_src/etc
- Create/Modify web.xml File here. Using the names above it should look like the following:[php]

authentication

hello_servlet

com.ArbitraryName.custom.hello_servlet

hello_servlet

/YetAnotherArbitraryName/greet_the_world

[/php]
4. Run make_toolkit and you are done! URL to call your JSP will be something like http://ServerName/iw-cc/YetAnotherArbitraryName/wu_dispatch.jsp

With so simple, starightforward, efficient and intuitive API I wonder who would need CGI/Perl? It's only three source Modules to change,
two Java Object bytecodes and the whole application to recompile - what could possibly be simpler to say "Hello World"?! But I digress...

Do I detect a hint of sarcasm Smiley Happy

Thanks for this post. It confirms that my .java files must be in customer_src/src. I think that was my only issue.

Do I detect a hint of sarcasm

No, banish the thought! I'm dead serious. Of course Java is the best thing since wonder bread - and as tasty

Remember that when you run make_toolkit.ipl, you will be taking down the TeamSite UI for a couple of minutes while if someone tries to access TeamSite at that time, they would say something about proxy server can't connect to servlet engine. And if your servlet has some errors, it might bring down the whole whole servlet engine too while busy users are waiting for you to fix the problem.
