Hi Asher,
You can make the change in the <server>/conf/standardjboss.xml file as follows (NB: I am assuming you're testing activation and passivation of stateful and stateless session beans):
<
jboss>
<!-- Stateless Session Bean -->
<container-configuration>
<container-name>Standard Stateless SessionBean</container-name>
<container-pool-conf>
<MaximumSize>100</MaximumSize>
</container-pool-conf>
</container-configuration>
<!-- Stateful Session Bean -->
<container-configuration>
<container-name>Standard Stateful Session Bean</container-name>
<<container-pool-conf>
<MaximumSize>100</MaximumSize>
</container-pool-conf>
</container-configuration>
</jboss>
Instead of modifying the conf/standardjboss.xml file, just create a copy of it, modify it as needed, and place it in your deploy directory under the name 'jboss-service.xml'. It will be read and its settings will kick in and override those of the conf/standardjboss.xml file.
You can also modify other settings here such as the time to activation and passivation, etc. For a full description of the settings, just read the appropriate comments in the '<jboss_home>/docs/dtds/jboss_3_0.dtd' directory.
I hope this helps.
