Thus, i call activate() to commit my changes. If I then look in the Web console the deleted resource is still there, and if I try to create it again it fails with error message indicating the MBean already exists. Why is this?

Did you approach Oracle Support about this? It seems like a bug especially if the console lets you deploy the same app w/o any issue. WLST directly uses the JMX MBeans to do the deployment and although console uses the Mbeans, sometimes it can do more validations and be more forgiving. Do let me know what you find. -satya ghattu Thats weird. Did you approach Oracle Support about this? It seems like a bug especially if the console lets you deploy the same app w/o any issue.

When I try to deploy EAR file using deploy command, it throws error saying application has invalid version identifier. I checked in MANIFEST-MF file and found that version included invalid characters such as curly braces. I removed them and it worked fine. My question is that why WLST throws error when application is deployed through WLST while no error is thrown when deployed manually through administative console? Is there any work aroud for this? Please help. If everytime I modify MANIFEST-MF file before running my scripts, it defeats the purpose of automation :-( Please note that no error is thrown when I deploy applications on Weblogic 8.1.6. Scripts written for Weblogic 8.1.6 work perfectly without any errors. Regards, Gaurav Hi Satya,

Hello Satya,

I am attempting to use WLSTInterpreter class in a webapp that also uses JMX to connect to Websphere and Weblogic. The JMX piece works fine and I can querry mbeans on both the servers. However, on the WLS side, when I attempt to invoke the WLSTInterpreter constructor I get the not-very-useful message:

Traceback (innermost last):
File "&ltiostream&gt", line 31, in ?
TypeError: cannot lazy load PyObject subclass

Now I am attempting to run this webapp in Tomcat 6.0.18. I know that Tomcat truncates the java.class.path to only include the bootstrap classes. So I looked at the code of WLSTInterpreter and it's collaborators and it seems that it IS relying on the classpath.

Can you tell me what class (within the WLST classes) throws that error?
I cannot even use dumpStack() because I cannot even get an instance of the Jython Interpreter!

Any help will be much appreciated!

Hi Satya,

I use Eclipse 3.4 that is not compatible with JyDT. so I use PyDev on Eclipse as Jython IDE.

But I can not import WLST. I have added wlstModule.py, weblogic.jar and jython-modules.jar to my project.

However I can use WLST in my IDE and have “ypeError: cannot lazy load PyObject subclass” error message.

What can be the problem?
