How to connect to existing engine on WLS via PAPI?

Question

Hi All,
I'm having an issue with Connecting to an existing engine on a weblogic server via PAPI from my local machine. The versions running are BPM 10gr3 and weblogic 10gr3. I'm essentially trying to run the tutorial provided in the PAPI guide from Oracle, but I'm trying to connect to a process deployed in one of our development environments. I get the following exception when executing the source code below. Only thing that pops out at me is that the path in the exception has back slashes whereas in the properties I specify the path with forward slashes. Any help would be greatly appreciated!

Please try to change the code for the below line
config.setProperty(ProcessService.DIRECTORY_PROPERTIES_FILE, "//home//weblogic//bpm103//conf//directory.xml");
to
config.setProperty(ProcessService.DIRECTORY_PROPERTIES_FILE, "c://conf//directory.xml");
Please get the directory.xml to your local machine and try.
