If you are curious to learn more about LiveCycle activity at the system level (file open/close/read/write, registry access, thread create/delete, network activity etc), there is an excellent tool available (only) on Windows. It is Microsoft’s own Process Monitor.
1) Download and run it.
2) Run Windows Task Manager and determine the Process ID of the java.exe process that represents the appserver instance that hosts LiveCycle. You also would want to do the same for LiveCycle processes that run outside the JVM such as XMLForm.exe as well as pdfgen.exe.
3) Apply filters so that only events related to these processes are captured and displayed.
Here’s a very detailed video about Process Monitor by Mark Russinovich, one of its creators. You need Microsoft Silverlight to view it.
