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

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hello Trever,

I noticed the following in your conf file:
wrapper.java.mainclass=org.tanukisoftware.wrapper.test.WrapperSimpleApp

please note that the classname is incorrect, it should read as:
wrapper.java.mainclass=org.tanukisoftware.wrapper.WrapperSimpleApp

Furthermore, thanks to the directory structure, you attached, I'd like to
point out that relative pathes in the conf file are relative to the
location of the wrapper.exe file.

In your directory structure, wrapper.exe (and the working dir) is
"C:\Documents and
Settings\hickeyex\Desktop\CenturaDataCollectionProgramDeployment\CenturaDataCollectionProgram12\"

When you defined your classpath elements, you had the following properties:
wrapper.java.classpath.2=../lib/wrapper.jar

which translated means:
C:\Documents and
Settings\hickeyex\Desktop\CenturaDataCollectionProgramDeployment\CenturaDataCollectionProgram12\..\lib\wrapper.jar

this path doesn't exist, however. So in order to specify the class path
correctly, please change this property (and the others) to
wrapper.java.classpath.2=./lib/wrapper.jar
wrapper.java.classpath.3=./CenturaDataCollectionProgram.jar
wrapper.java.library.path.1=./lib

Hope this information helps you out.

Cheers,

Christian
