Juan, One problem is that your wrapper.dll file is not being located correctly. See the following error: --- INFO | jvm 1 | 2010/06/17 22:53:07 | WrapperManager Debug: Unable to load native library: wrapper-windows-x86-32.dll Cause: no wrapper-windows-x86-32 in java.library.path INFO | jvm 1 | 2010/06/17 22:53:07 | WrapperManager Debug: Unable to load native library: wrapper.dll Cause: no wrapper in java.library.path INFO | jvm 1 | 2010/06/17 22:53:07 | WrapperManager: INFO | jvm 1 | 2010/06/17 22:53:07 | WrapperManager: WARNING - Unable to load the Wrapper's native library because none of the INFO | jvm 1 | 2010/06/17 22:53:07 | WrapperManager: following files: INFO | jvm 1 | 2010/06/17 22:53:07 | WrapperManager: wrapper-windows-x86-32.dll INFO | jvm 1 | 2010/06/17 22:53:07 | WrapperManager: wrapper.dll INFO | jvm 1 | 2010/06/17 22:53:07 | WrapperManager: could be located on the following java.library.path: INFO | jvm 1 | 2010/06/17 22:53:07 | WrapperManager: C:\Documents and Settings\cooljsh\Mis documentos\chamba\cachuelo2\DEPLOY\MonitorLanCenter\lib INFO | jvm 1 | 2010/06/17 22:53:07 | WrapperManager: Please see the documentation for the wrapper.java.library.path INFO | jvm 1 | 2010/06/17 22:53:07 | WrapperManager: configuration property.

This can happen if 1) something in the JVM calls System.exit. 2) All non daemon threads complete. Both of these cases are normal operation and can be fixed in your application. If your wrapper.dll was being loaded then I would be able to say for sure because of a relevant log message. But without the wrapper.dll, it is also possible that the JVM is receiving a system signal directly which could cause the shutdown. In your case, I don't this is happening however because you are not logging off or anything when the shutdown takes place. Do you have access to the source to see if System.exit is being called? You might want to try adding the following while debug output is enabled. It will cause the Wrapper to log a thread dump as soon as it starts to shutdown. This will show you if all of the non-daemon threads have completed. --- wrapper.filter.trigger.1=ShutdownHook started wrapper.filter.action.1=DUMP --- Please let me know how this works for you.
