Error in jar file but not when program is run as standalone

Hello,

I created a program in java when i compile it javac filename.java and run it java filename using the command line it runs perfectly. The problem I am having is when i make a jar file using this command line jar cfm filename.jar man.tx filename.class filename.png it creates the jar file filename.jar but when i try and run it using this command line java -jar filename.jar it gives me these errors:

Exception in thread "main" java.lang.NoClassDefFoundError: SchoolVue$1
at SchoolVue.RunSchool(SchoolVue.java:97)

I've even created a manifest file that contains Main-Class: className and it still doesn't work.
Does anyone have a clue as to why this is happening?

Can you elaborate all steps how you make your JAR?

You have to include all .class files. Including those with names like filename$1.class, filename$1.class etc. Those are the class files for your anonymous inner classes.

But first, you should have looked at the stack trace.

What's on line 97 of SchoolVue.java? I'll bet there's a new ... statement which tries to instantiate the first declared anonymous inner class.

I give descriptions how I created the jar file in the original post as well as how I created the class file with javac. But here it is again:

jar cfm jarfile.jar man.txt classFile.class picture.png

line 97 is the end of an actionlistener { ); } i surrounded it in curly braces

When class file is created does it create a second class file with $1 appended to it?

Thank you very much I created a new jar file and include the name of class file with the $1 appended and it worked. Bless you. I've been trying to figure this out for 2 days.

When you compile a java file that contains anonymous classes in it it will create a class file for each of those anonymous ones, appending $n to the end (where n increments).

Similarly for named inner classes, where the class file produce will be called <parentclassname>$<innerclassname>.class.
