[jboss-user] [Security] - JBossNegotiation NullPointerExcpetion on EJB Call after Cach

[j_ri]

Hi,

this week I gave JBossNegotiation a try. I tried it with a webapplication which calls a stateless session ejb.

In the first step authentication works well, but after the SecurityManager Cache timed out, the next call from the webapp to the EJB fails with a NullPointerExcpetion:

Is there a solution for this problem, if I don't want to change the "DefaultCacheTimeout" in the "org.jboss.security.plugins.JaasSecurityManagerService" MBean to a very long time?

How does this work with failover in the cluster?

Thanks,
Jochen
