I have a jar file "Recon_AccessCodeGenerator.jar"  which contains a class with two methods, after uploading the jar file it doesn't show with the name of jar file.My requirement is to access methods with in the jar file after making it available in pega. What are the other ways to use the jar file in pega other than uploading?

After uploading jar file package and classes are shown as above.Since this is added to customer codeset is it by default accessible using java coding inside functions and activity or do I need to extract the [pzbinarycontent] column using a java code
