Well, in the meantime I tried to implement generation of an image after workflow is deployed.
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!

Hey guys, I am working on jbpm 4.4 and Spring 3 Integration. I currently have Spring & jbpm starting without errors.
But when I try to kick off a simple process, I get the following error:
Does anyone have any ideas?

[jBPM] - jBPM 4.4 - How to deploy a business archive ?

Greetings,
The jBPM 3.x GPD, in the Eclipse jBPM perspective, had a tab named Deployment on the behalf of which one could deploy a business archive. With GPD 4.x this tab seems to have disapeared. The documentation doesn't insist much on the deployment, even if this is one of the most important topics. Instead, the only information the documentation is giving concerning the deployment is the ant JbpmDeplyTask.
Is that possible that the only way to deploy a jBPM 4 business archive be on the behalf of ant ? Why such a regression ? I expected to be able to deploy with the Add or Remove function in the Eclipse JBoss view, but no way ! I also expected to find in the jBPM Console a deploy function, as in any console. I didn't find anything.
So how is one supposed to deploy a business archive ? I can't beleive that, after spending time and money to develop a nice visual tool as GPD, one decided that the generated result by GPS has to be deplyed with ant !
Please advice.
many thanks in advance.
Nicolas
