Error in import lca\application code

Hi, I am getting this run time error.. at my code line

//Create a ProcessTemplateDocument object

ProcessTemplateDocument processTemplateDocument = ProcessTemplateDocumentFactory.parseProcessTemplate(configuration.getDescriptor());

orchestration.setDescription(processTemplateDocument.getDescription());

orchestration.setId(processTemplateDocument.getName());

orchestration.setCategoryId(catId);

orchestration.setCategoryDescription(catDesc);

I have added these jar files
