So I did try Christian's advice on using the WrapperSimpleJarApp and it looks like my application is working. It seems to be a much easier way to integrate JAR applications. Anyways, thank you for the great advice. Sincerely, Trever Hickey ________________________________ From: jeroen vranckx [mailto:jvr...@gm...] Sent: Monday, April 23, 2012 10:32 PM To: wra...@li...

Make sure that the main-class name of your application that you have specified is correct. I am using the "Default Package" in Eclipse, so I was wondering if this has been an issue when detecting a class? Do I have to use the unzipped version of my JAR file and/or include the dependent jar files in my class path? First check if the main-class is correct. It could be indeed, that the problem is, that you need to specify all the jar files which are needed to run the application in your classpath. You can always try the process of trial and error. You can't do much wrong by trying different things out. As christian will probably know more of this, and will be able to give you specific information, it's best for his response maybe. grtz, jeroen On 24 April 2012 00:50, Hickey, Trever (INTERN) <Tre...@si...<mailto:Tre...@si...>> wrote: Thank you for catching that parameter being commented out.

This line doesn't give much information about what is going on. Can you post some additional information? also, i scrolled through your config and noticed the following which maybe could give you some issues. 1) delete that commented out wrappertest.jar and shift everything one up, so you'll get this.probably won't do anything, but i have something against unnecessairy commando's ^^ wrapper.java.classpath.1=./lib/wrapper.jar wrapper.java.classpath.2=./CenturaDataCollectionProgram.jar 2)You actually kinda guessed it yourself, but the wrappersimpleapp class will need to know what the main class is of your own application. You need to specify the mainclass-name of your own application with application parameters. I can see the following commented out in the config file: # Application parameters. Add parameters as needed starting from 1 #wrapper.app.parameter.1= CenturaDataCollectionProgram.Program change it to: wrapper.app.parameter.1= CenturaDataCollectionProgram.Program grtz, jeroen On 23 April 2012 18:01, Hickey, Trever (INTERN) <Tre...@si...<mailto:Tre...@si...>> wrote: Dear Christian, I took your advice and thank you again for clarifying the class path issue I had.

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.

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....

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?
