i am using linux please help me how to solve this error

[Norm]

Do you have the jar file that contains the missing class?
If so you need to put it on the classpath for the jvm to use.

[baktha.thalapathy]

please reply which jar file missing

[Norm]

The one containing the class: com/sun/star/lang/XEventListener
The class must have been available to the compiler(javac) when the program using that class was compiled. Find that jar file and put it on the classpath for the java command.

Where do the packages: com.artofsolving.jodconverter come from?
