Mourad Jaber,   If you want to deploy process definition from inputStream.  You have to set a name for this InputStream.  And this name must end with ".jpdl.xml".  So jBPM 4 could know how to deploy it.   Your problem is the name did not end with '.jpdl.xml'.  So jBPM 4 did not know how to deploy it.  And just store inputStream as a plain blob.   But the error information of jBPM4 is strange.  We should review it and let it report the correct information. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/541877#541877] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
