[JBoss jBPM] - PropertyAccessException trying to deploy ProcessDefinition
by chip_schoch
JBossAS 4.2.2 JBM 3.3.0.GA
I am trying to deploy a ProcessDefinition from within my code and I get a PropertyAccessException.
ProcessDefinition processDefinition = ProcessDefinition.parseParZipInputStream (zis);
| jbpmContext.deployProcessDefinition (processDefinition);
I get:

[JBoss jBPM] - Re: Process image upload
by pieter.martin
Hi,
I our app we include the picture in the par file deploy it and then later extract it again.
Relevant code:
| graphSession.deployProcessDefinition(ProcessDefinition.parseParZipInputStream(new ZipInputStream(new ByteArrayInputStream(parFile))));
|
| Criteria query = ManagedJbpmContext.instance().getSession().createCriteria(ProcessDefinition.class);
| List<ProcessDefinition> anarchyProcessDefinitionList = query.list();
| for (ProcessDefinition process : anarchyProcessDefinitionList) {
| if (process.getName().equals(processInstance.getProcessDefinition().getName())) {
| FileDefinition fileDefinition = process.getFileDefinition();
| dribbleSvg = fileDefinition.getInputStream("processimage.svg");
| break;
| }
| }
|
Cheers
Pieter
