Class not found, Jar not executing

Question

Hello,
I created a JAR file and cannot execute it by running java -jar myjarfile.jar. I get no error message and it does not execute.
If I extract the JAR, and run my main class with java packagename.myclass it works fine
If I run javaw myjarfile.jar it tells me it cannot find the main class
My manifest file looks like this:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.0
Created-By: 1.5.0_14-b03 (Sun Microsystems Inc.)
Main-Class: mypackage.Main
This program works fine when unjarred and also from my IDE.

Ok, in that case - is this behavior acceptable:
The first thing I do is:
configFile = reader.read(System.getProperty("user.dir") + "\\CustomConfig.xml");This stores the xml file in a variable of type document (which represents an xml document)
From that point forward I have all the info I need. Can I do this inside a JAR?
Additionally, do you have any feedback on how I can fix what seems to be a classpath issue. What command should I be using to run my JAR file to ensure that it is able to find "mypackagename.Main"
Thank you!If I understand correctly, the file CustomConfig.xml is inside the jar. You do not need user.dir because getClass().getResourceAsStream() will look inside the jar, assuming the object you use was loaded from the jar. If I remember correctly, if your class is in a named package, you need to start the file path string with a / character - ...getResource("/CustomConfig.xml").
Second question: If you correctly specify the main class, then you just need java -jar yourjarfile.jar
