I am struggling to list active threads from a thread pool WebContainter in WebSphere Application Server 8.5.5. Can someone help me out? I am a beginner on WebSphere.

wsadmin.sh -lang jython -c "print AdminControl.queryNames ('name=WebContainer,process=server1,platform=dynamicproxy,node=node1,version=8.5.5.8,type=ThreadPool').splitlines()"

The command you are using will actually query for thread pool configurations rather than display threads. I think you are missing the ,* at the end of the object name, which is why it wouldn't be showing any thread pool configurations. For example,

'name=WebContainer,process=server1,platform=dynamicproxy,node=node1,version=8.5.5.8,type=ThreadPool,*'

In order to view thread stacks of active threads, one option would be to run the following command to generate a javacore, which goes into the root folder for your profile,

jvm = AdminControl.queryNames('type=JVM,process=server1,*')
AdminControl.invoke(jvm, 'dumpThreads')

You can use Thread Analyzer to list and investigate the thread dump. Download jca.jar : https://www.ibm.com/developerworks/community/groups/service/html/communityview?communityUuid=2245aa39-fa5c-4475-b891-14c205f7333c
