[Wrapper-user] DCOM and wrapper

[Philip K. <pk...@sp...>]

My application is a WMI (Microsoft Wbem) java application.  I have used JNI
to access WMI via DCOM.  The applications works fine if it is run via the
command line and java.  It does not work within wrapper.  I believe the
problem is how I am "passing" the pointer to the IWbemServices object.  In
msdev debug I do not seem to retain a valid object (via pointer) of the
object that I need methods of in additional JNI calls.  I have two JNI
functions.  One that creates and connects to WMI via DCOM then stores the
pointer into the java environment (in the object that makes the function
call to JNI).   The second uses methods of that WMI object via the pointer
to retrieve system data, this methods is used several time through out the
application.  Any ideas and thought would be helpful.

 

Does wrapper some who create new threads for these JNI calls?   Do I need a
better means to pass the pointer?  Is there a what to protect the memory of
that pointer?

 

Thanks!
