[JBoss Seam] - NullPointerException in LogImpl
by c_eric_ray
During activation of a passivated bean I get the following exception.
My code:
| @Logger
| private Log log;
|
| @PostActivation
| public void activate() {
| log.info("activating bean");
| }
|
The exception:
| Caused by: java.lang.NullPointerException
| at org.jboss.seam.log.LogImpl.isInfoEnabled(LogImpl.java:45)
| at org.jboss.seam.log.LogImpl.info(LogImpl.java:92)
| at com.vicor.distributedcapture.session.PackageAction.activate(PackageAction.java:728)

| at org.jboss.ejb3.interceptor.LifecycleInvocationContextImpl.proceed(LifecycleInvocationContextImpl.java:159)
| at org.jboss.ejb3.interceptor.LifecycleInterceptorHandler.postActivate(LifecycleInterceptorHandler.java:139)
|
Am I not allowed to have code like that or is this an issues with the seam logger?
Thanks.
Eric

[JBossCache] - Re: JBossCache as a message oriented middleware?
by bstansberry＠jboss.com
Can you divide your data between different caches? I.e. if on servers 1 and 2, there are processes running that are interested in data structures A, B, and C, then you deploy CacheA, CacheB and CacheC. On servers 3 and 4, the running process are interested in B, C and D, so CacheB, CacheC and CacheD are deployed.
Another possibility is to use the activateRegion() API. There you have just one cache, but it has regions /A, /B, /C and /D. On servers 1 and 2, region /D isn't activated, and thus the cache ignores replication traffic for /D. On servers 3 and 4, /A isn't activated.
The multiple-cache approach has the advantage that no JGroups channel on servers 1 and 2 even sees replication messages for D. With the region-based approach, the channel sees the messages and passes them all the way up to JBoss Cache, where they are then ignored.

[JBoss jBPM] - Exception instancing process
by cocampo
Hello:
Tom, Roland, Koen, I hope you jBPM guys can help me (anybody else's help is apreciated too, but as this seems to be a jBPM API problem...)
Tools:
JBoss 4.0.4GA, jBPM 3.1.2, jBPM DB is running on MySQL 5.0, JDK 1.5.08.
I'm having an exception while instancing a process.
Here is the error:

This is my process definition:

|
And finally, here is the line where I'm getting the exception...
| ProcessInstance processInstance = jbpmContext.newProcessInstance("proceso_perfil_proveedor");

It looks OK to me, but as soon as the values retrieved try to be assigned to a ProcessDefinition-type variable, I got the "ClassCastException".
I've been dealing with this problem for about a week, so any help would be mostly apreciated.
It seems to be an error while executing the next query:
Thanks in advance.
