file. This will cause the program to stop working.
The most common problem
encountered when trying to run PaperScope is having the wrong
version of Java, or an incorrectly configured Java installation.
PaperScope currently requires Java 6 to function, and the
JAVA_HOME environment variable must be properly configured.
The three main errors are:
Wrong version of Java -
If you are running an older version of Java you will get the
following error when trying to run PaperScope
thread "main" java.lang.NoClassDefFoundError: javax/swing/SwingWorker
If you see this error then update
to the latest version of Java and try running PaperScope
again (Download Java 6 here).
Classpath error - If you
do not have the current directory (or the folder containing
PaperScope.jar) on your classpath you will see the following
thread "main" java.lang.NoClassDefFoundError:PaperScopeUI
If you see this error then try
adding '.' to your classpath, or add the directory
You can also solve this problem by running PaperScope with
the following command:
java -jar -classpath
JAVA_HOME not properly configured
- If you are getting an error
saying that "java" is an unknown command then you have not
properly configured the JAVA_HOME environment variable.
Instructions on how to do this are operating system
Linux - add the following line to your profile and be
sure to source it afterwards (.profile, or .bashrc, etc...):
Right click on "My Computer", select "Properties".
Click on the tab labeled "Advanced" and click the
"Environment Variables" button. Click the "New" button
under "User variables for..." and enter 'JAVA_HOME' as the
variable name, and the complete path to your Java
installation as the variable value. Click the "OK"
