Cannot open page http(s)://<server>:<port>/useradmin with exception java.util.ConcurrentModificationException

[Former Member]

Good morning,

I am performing installation of Solution Manager 7.1 SPS 7, currently running on JDK 6 because of Wily Introscope version 9. When I was trying to downgrade JDK it was not possible to start it again with JDK 4 or 5 with message about old version.

During step of creation users SAPSUPPORT and SM_COLL_SID for Java part I am getting this error:

User J2EE_ADMIN is not allowed to perform this request. Check SAP Note 1647157.

This note is about creating new role to allow access to SPML service, but when I am accessing
http(s)://<server>:<port>/useradmin I get following error:

500   Internal Server Error
		SAP NetWeaver Application Server 7.00/Java AS 7.00

Only option was reinstall and do not use jvm 5 or 6. Just let some bundle installation (for example wily EM ) install their own separately, but next attemp with JVM 4 was without problem.

Hi Matej,

Now with new version of java , we need to use SPML services to access data.

The administrator user created during the installation will not have all the implicit roles which it used to have with previous version.

So you can follow the SAP Note 1647267 - Solution Manager adaptation to Java UME security.

With Regards
