SAP Netweaver CE 7.1 - Cleaning up JAVA Netweaver Cache Procedure???...

Question

Good Afternoon,
One of my clients has a SAP Netweaver CE 7.1 (EHP1) and there are several development team developing using the CAF in the system (several webservices, etc...).
One of the development teams is requesting a Netweaver Java Cache cleanup... The argument is that some objects developed by them should be in the system cache and the cache needs to be clean in order to reset these objects... So they're asking for a instance restart in a productive system, and they're asking that in a regular basis.
My administration knowledge is SAP ABAP systems related, i don't have deep knowledge in SAP JAVA instances. I've tried to find information about it but i don't find any procedure to do that manually without restarting the SAP system.
Does this cleanup of the Netweaver JAVA cache, makes sense to be asked to do? Is there any procedure (standard SAP) in order to do this without restarting the SAP instance?
Any help will be appreciated.
Thanks,
Pedro Gaspar

From Control Panel, go to Java -> General tab, Temporary Internet Files
-> View... -> Delete all the content there.
Then go to:

> Java Web Start Administration
> Restore Archives and Generate New Signature
Portal Caches
The main portal caches are:
u2022     Navigation cache
u2022     PCD cache
u2022     Portal runtime cache
u2022     Database cache
u2022     UME cache
Navigation cache
To clear the Navigation cache:
System Administration -> Navigation
Clear the cache for the ROLES connector.
PRT cache
The content admin can enable portal content to be cached in the memory by the portal. This content will be stored in the portal runtime cache. This cache is actually storing iView content.
To clear the PRT cache:
http:// server:port /irj/servlet/prt/portal/prtroot/com.sap.portal.prt.cache.PRTRegionMemoryClear
PCD cache
To clear the PCD cache:
System Administration -> Support -> Support Desk -> Portal Content Directory -> PCD Administration
Database cache
To clear the DB cache:
http:// server:port /irj/servlet/prt/portal/prtroot/com.sap.portal.prt.cache.PRTRegionDBClear
UME cache
To clear this cache:
System Administration -> System Configuration -> UME Configuration -> Support -> Invalidate cluster wide cache
HTTP Provider Cache
This is the cache for static files like CSS, Javascript, Images, HTML. You`ll have to clear this cache when you redeploy an application and receive Javascript errors. To clear this cache:
Visual Administrator -> Cluster -> Server # -> Services -> HTTP Provider
