jbpm-starters-kit-3.1.3 has sources of the web application, and uploading servlet works fine with created by plugin archives. Here is a snip of a code: | ZipInputStream zipInputStream = new ZipInputStream(fileItem.getInputStream()); | JbpmContext jbpmContext = JbpmContext.getCurrentJbpmContext(); | ProcessDefinition processDefinition = ProcessDefinition.parseParZipInputStream(zipInputStream); | log.debug("Created a processdefinition : " + processDefinition.getName() ); | jbpmContext.deployProcessDefinition(processDefinition); | zipInputStream.close(); | return "Deployed archive " + processDefinition.getName() + " successfully"; | How you should see, par file is a simple zip archive with some special structure. In the root folder should exist gpd.xml processdefinition.xml processimage.jpg in classes folder you can put necessary classes View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4048603#...
