[jbpm-issues] [JBoss JIRA] Closed: (JBPM-2127) Can't use addInputStream() to deploy a process

Can't use addInputStream() to deploy a process ---------------------------------------------- Key: JBPM-2127 URL: https://jira.jboss.org/jira/browse/JBPM-2127 Project: JBoss jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.0.0 Alpha2 Environment: winxp Reporter: Xu Huisheng Assignee: Tom Baeyens The following codes will cause an Exception, that inputStream is already closed: List<ProcessDefinition> processDefinitions = processService.createDeployment() .addInputStream("process.jpdl.xml", this.getClass().getResourceAsStream("/process.jpdl.xml")) .deploy() .getProcessDefinitions(); The exception info is like this: Caused by: java.io.IOException: Stream closed at java.io.BufferedInputStream.getBufIfOpen(BufferedInputStream.java:14) at java.io.BufferedInputStream.read(BufferedInputStream.java:308) at java.io.FilterInputStream.read(FilterInputStream.java:90) at org.jbpm.pvm.internal.util.IoUtil.transfer(IoUtil.java:55) If I use addResource() instead of addInputStream(), then the deployment will success. I read the code of jBPM-4.0.0.Alpha2 and find the execute() method of org.jbpm.pvm.internal.xml.Parser always close the inputstream after parse it. But on next step of deploy, the SaveDeploy should read attachment bytes from the inputstream. Then the Exception occured. I find the openStream() of org.jbpm.pvm.internal.stream.InputStreamInput always return the same inputStream, however the openStream() of org.jbpm.pvm.internal.stream.ResourceStreamInput will create a new inputstream every time, so it won't cause the problem. I think this is may be the reason.
