I tried to get image with the following code:         NewDeployment deployment = repositoryService.createDeployment();         String name = workflow.getName().replaceAll(" ", "_");         String key = deployment.addResourceFromString(                 name + "_" + workflow.getVersion() + ".jpdl.xml",                 workflowSerializer.serialize(workflow)).deploy();         ProcessDefinitionQuery pdq = repositoryService                 .createProcessDefinitionQuery();         List<ProcessDefinition> processDefinitions = pdq.processDefinitionKey(                 key).list();         for (ProcessDefinition pd : processDefinitions) {             String imageName = pd.getImageResourceName();             File f = new File("/home/bofh/" + imageName);             try {                 FileOutputStream fos = new FileOutputStream(f);                 System.out.println("Created file " + f.getAbsolutePath());                 InputStream imageInputStream = repositoryService                         .getResourceAsStream(pd.getDeploymentId(), imageName);                 byte[] buffer = new byte[10240];                 int read = 0;                 while ((read = imageInputStream.read(buffer)) > 0) {                     fos.write(buffer, 0, read);                 }                 fos.flush();                 fos.close();                 imageInputStream.close();             } catch (Exception e) {                 e.printStackTrace();             }         } However the name of image at line String imageName = pd.getImageResourceName(); is always null, which causes NPE on getting the actual image stream Am I missing something? Thank you in advance! -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/558152#558152] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
