I also read somewhere on the Java Service Wrapper website that their is not support for runnable JARs. http://wrapper.tanukisoftware.com/doc/english/faq.html#2 My Runnable JAR includes about 7 other JAR files its dependent on. Will I have to include a reference to everyone of them?

Subject: Re: [Wrapper-user] FW: Advice on configuring the Java Service Wrapper for I/O heavy application Hello Trever, A java.lang.ClassNotFoundException means that the JVM didn't find the wrapper.jar file on the class path. could you please verify that the jar file is added correctly to the class path? >From your first mail, I can see that you have the following setting: wrapper.java.classpath.2=../lib/wrapper.jar Furthermore, you need to add your jar file also to the classpath: wrapper.java.classpath.3=./CenturaDataCollectionProgram.jar Lastly, the name of your main class is commented out: #wrapper.app.parameter.1=CenturaDataCollectionProgram.Program If that's the correct name of your main class, please remove the comments. Hope this information helps you out.

The reason, your JVM stops after 30 seconds is basically because of a small misconfiguration. Please get rid of the following line in your conf file: wrapper.java.additional.2= -jar "./CenturaDataCollectionProgram.jar" Actually, with this line you kind of intercept the logic of how the JVM will interpret the command line.... Hope this helps you out.

I am trying to turn my Java Application into a Windows service using Simple Server App class.

I have also included my log file and conf file. The errors I think it most likely relates to are ERROR | wrapper | 2012/04/11 11:37:40 | Startup failed: Timed out waiting for a signal from the JVM.

I believe this might be one of two issues. One my application stays constantly within my main method and doesn't exit out. I think there are a couple of parameters that can be set to handle this, but I haven't had much luck. Second idea is my application is very I/O heavy. My program is constantly collecting data from a tool [using a special communication protocol] and writing it to a log file. Could the JVM be timing out because of the heavy I/O and if so, is their a way around this so my program can still be a Windows Service? If anyone has any advice for handling this type of error I would appreciate it.
