Re: [Wrapper-user] FW: Advice on configuring the Java Service Wrapper for I/O heavy application

Hello Trever,

thank you for your mail.

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.

Best Regards,
Christian
