As a partner with PTC, we have a jsp plugin for Windchill. Does anyone know where the java class Cache resides or how to delete the class cache without restarting Windchill?

Please see PTC Document - CS29555 and PTC Document CS75448.

You can delete the cache, located at <Windchill Home>\tomcat\instances\, without restarting the Tomcat service but the changes will not take effect until you do.

Are you wanting to do this for testing as you develop a site or just to update with a new version?

The reason I ask is you can set the value of web.xml for development from false to true and then all changed will be instantly live. This should only be used in a pilot environment for testing.

Open web.xml found here: d:\ptc\Windchill_10.0\Windchill\tomcat\instances\instance-8010\conf\web.xml

Then look for the following lines and change the value of false to true:

<param-name>development</param-name>

<param-Value>false</param-value>

You will also need to restart the method server but after that you can keep making changes to the .jsp page and they will be live. Also note: if you clear the tomcat cache you will need to set this preference again as the default is false.
