error on serialization object
amy3k May 3, 2010 5:44 AMhello,
i new to jbpm and i have a little (but for me is big and urgent problem)
i have 2 web service - one is for "core"(WScomponents) and the second one is for creating a JBPM workflow(WSprincipal) that manage an application
in WS principal i appeal one method from WScomponents that return a list of a custom object named "folder" (=> List<folder>), this list i've tried to put this in a jbpm variable like this:
<java g="270,290,92,52" method="getAllFolders" name="getAllFolders" var="folders">
<arg><object expr="#{pathID}"/></arg>
<arg><object expr="#{username}"/></arg>
<transition g="-62,-35" name="to preluareVar" to="preluareVar"/>
</java>
but in the method getAllFolders i've get an error like this:
org.jbpm.pvm.internal.wire.WireException: couldn't invoke method getAllFolders: couldn't serialize '[wscomponents.Folder@129e910]'
