Hi All,
Made a checkout of modules in JBoss Tools from trunk. The modules are seam, build, hibernate along with the complete folder structure and pom.xml, bootstrap-pom.xml & build.xml.
However towards maven clean from eclipse for seam module following exceptions are thrown:
[ERROR] The build could not read 39 projects -> [Help 1]
[ERROR]
[ERROR] The project org.jboss.tools.seam.features:org.jboss.tools.seam.feature:3.2.0-SNAPSHOT (D:\PRATHAMESH\ENVIRONMENT\WORKSPACES\source-jbosstools\trunk\seam\features\org.jboss.tools.seam.feature\pom.xml) has 1 error
[ERROR] Non-resolvable parent POM: Could not find artifact org.jboss.tools:org.jboss.tools.parent.pom:pom:0.0.2-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ line 4, column 10 -> [Help 2]
.
.
Note: The screenhot of my project setup is atatched with this discussion.
Please let me know how can I build the mavenized JBoss Tools: Seam. Any related stuff will be helpful.
Thank you in advance.

[JBoss Microcontainer] - Custom Deployer - migrate from JBoss4.2

In JBoss4 there is a class +org.jboss.deployment.SubDeployerSupport+
Using this class I'm develop custom deployer, that now used in development and production too.
In that deployer I'm override method
+protected void processNestedDeployments(DeploymentInfo di)+
and some other methods too.
Using internal config file +deployment.xml+ I'm *sort and filter subdeployments* as needed by business requirements. Obtain information about deployed package and deployment status. I'm create MBean for obtain information about sub-deployments via JMX console. And more other things...
Now our team planned to migrate on JBoss5 (may be 6). And I see that +SubDeployerSupport+ is comletely not usefull in JBoss 5 and later.
I'm trying to use classes:
* +org.jboss.deployers.spi.deployer.helpers.AbstractDeployer+
* +org.jboss.deployers.vfs.plugins.structure.AbstractVFSStructureDeployer+
With some settings such as:
* +setStage(DeploymentStages.INSTALLED);+
* +setStage(DeploymentStages.PRE_REAL);+
* +setRelativeOrder(...);+
With a combination of such parameters I'm can obtain deployment status and list of deployments. But I'm still can't sort and filter subdeployments!
+*The question was: how I must use Deployer in JBoss5 (6) for sort and filter subdeployments?*+

[EJB3] - way too many SLSB instances eventually cause heap to run out

"way too many SLSB instances eventually cause heap to run out"

In the RHQ 3.0 server, we use JBossAS 4.2.3's bundled EJB3. A user has reported seeing way too many SLSB instances slowly building up in heap and eventually causing the server to run out of heap (see his post from the rhq-devel list below). Can anyone shed some light on what could be causing it? Is it a bug in the EJB container, a bug in our application code, or just some configuration setting we need to adjust?
Thanks,
Ian

> Following up a post from about a month ago. We were seeing a persistent slow memory leak in the rhq server in tenured gen space that eventually led to an out of memory exception after running the server for about a week. I captured a heap dump and found hundreds of thousands of stateless session beans in memory. Here's a snapshot from my profiler of a table of classes with greatest number of instances.

So I started to wonder why there were so many slsb's in the ThreadlocalPools and after some digging found this ( http://community.jboss.org/message/363520#363520 http://community.jboss.org/message/363520) thread that sort of describes what I'm seeing. I still don't know why it's happening but it gave me something to try. I changed the Stateless Bean pool class in ejb3-interceptors-aop.xml from ThreadlocalPool to StrictMaxPool. Now when I run the server and watch it with my profiler I see at max 3 SubjectManagerBeans in memory. Same appears to be true for other slsb's. This isn't a solution to the problem but I'm hoping someone can shed light on what's really going on. I would be happy to upload the heap dump to somewhere public but it's almost a GB in size.
