Troubleshooting problems
Now and again there may be a problem running Jrar. Below are problems we know about and current ways of fixing the problem
Could not find the main class. Program will exit.
Exception in thread "main" java.lang.NoClassDefFoundError: Jrar
These problems are usually due to Java being incorrectly installed. To fix this you can try re-installing the runtime environment (this will also mean other Java programs shouldn't produce this error) or you can create a shortcut with the following as it's target
java -jar <path to Jrar>\Jrar.jar
If the error still persists put the full path to the java program
Error 3: java.lang.NegativeArraySizeException
You can get this error if you've tried to open a RAR archive and the (UN)RAR executable is not available in the current directory or in the PATH list. The easiest way to resolve this is to copy the RAR and UNRAR files to the same folder as the Jrar JAR file. The RAR and UNRAR executables can be found at www.rarlabs.com
