Query on livesite pre-controller

Hi,

I am trying to implement pre-controller in my project. I have written component having precontroller code as:

[html]
Content XML

com.interwoven.livesite.runtime.controller.impl.SampleTask
methodOne

com.interwoven.livesite.runtime.controller.impl.SampleTask
methodTwo
Some value goes here
Another value here

com.interwoven.livesite.runtime.controller.impl.SampleTask
methodOutput

com.interwoven.livesite.runtime.controller.impl.SampleTask
methodRedirect

Appearance

[/html]

and added this component in a page. My SampleTask.java file is attached with this forum.

I have put this java file at location

"/usr2/Interwoven/TeamSite/local/config/lib/content_center/livesite_customer_src/src"

and then run the toolkit.

Now when I am hitting the URL

"http://servername/mysites/sitename/PreControllerPOC.page?&submit=true&ComponentID=1264614790248&iwPreActions=one;"

nothing is happened Smiley Sad

.
Please suggest me how I can find if there is any error and also suggest me if there is any other way to implement pre controllers.

Thanks in advance.

Are you seeing anything in your servletd logs?

You may have an older version of Livesite where an actual External is required to process the controllers. Create a simple external that returns null and add it to the component. This restriction was removed for TeamSite 7.0 but previously it needed some external to be present even if it did nothing.

Thanks Alex for your reply.

I am trying to add this as you suggested:-
[html]

com.sci.dm20.livesite.common.NullObject
returnNull

[/html]

but I am getting this error:-

Caused by: java.lang.ClassNotFoundException: com.sci.dm20.livesite.common.NullObject

Make sure it is in the classpath and visible to the class loader (e.g. public class, jar in class path, etc).

Alex,

Thanks.
This error has been resolved. I have added this component (having controller and external) to a page named as PreControllerPOC.page. Now when I am hitting the URL

http://servername/sites/sitesname/PreControllerPOC.page?&submit=true&ComponentID=1264614790248&iwPreActions=one;

I am not getting anything in my logs and controller is not executing.
Please suggest what should I do to resolve this.

Thanks.

Can you set the log4j.xml level for com.interwoven.livesite to DEBUG and restart and hit that URL again and post the log?
