I follow exactly as JBPM Developers Guide session "16.3 Usage" to setup related XML. However, still cannot find the Spring Bean (my case is "TestCon" ).
The following are the XML and result.
***process.jpdl.xml(JBPM flow definition)***
<?xml version="1.0" encoding="UTF-8"?>
|
| <process name="process" xmlns="http://jbpm.org/4.0/jpdl">
|
| <start g="29,189,48,48" name="start">
| <transition g="-74,-18" name="to doSomeThing" to="doSomeThing"/>
| </start>
|
| <java expr="#{TestCon}" method="createProduct" name="doSomeThing" g="178,89,80,40">
| <transition to="printSomeThing"/>
| </java>
|
| <state g="383,196,111,52" name="printSomeThing">
| <transition g="-23,-20" name="to end" to="end"/>
| </state>
|
| <end g="563,199,48,48" name="end"/>
|
| </process>
