There is a webservice called UMWebService in the standard portal installation (EP 6.0, SP09 on WAS 6.40, Netweaver Developer Studio Portal Webservice Checker). When we try to run this, it gives java.lang.IllegalAccessError. Is there anyway we can reduce the security level of this out of the box webservice? I already tried changing the security zone for access to Everyone and Anonymous Users. Is this a patch related thing or is there any other security setting? Any help or thoughts will be appreciated.
