where to store action?database or runtime classes?

[windspy]

here is piece of process definition:

<start-state name="new disclosure-assitant">
<task name="Assistant new a disclosure" swimlane="assitant">
...
</task>
<event type="node-leave">
<action name="initial" class="idap.process.initial.InitialGlobalVariables" />
</event>
<transition name="default" to="choose avaiable time-board" />
</start-state>

<task-node name="choose avaiable time-board">
<task name="Bd choose time" duedate="36 hours">
<assignment class="idap.process.delegation.BoardMembersAssign" />
...
</task>

<event type="node-leave">
<action class="idap.process.derived.StoreParticipants" />
</event>
<transition .../>
</task-node>

deploy.xml like:

<copy todir="build/invention/classes">
<fileset dir="build/classes.idap" includes="idap/process/**" />
</copy>

and the actions in the start-state node and the assignment class works fine,either deploy in the database or put int runtime classes folder in web-inf of application,but the action of idap.process.derived.StoreParticipant can not works in both of methods.it throws:

but i searched in the database,tables of jbpm_bytearray and jbpm_byteblock,the action classes' file path and data are all complete.

why?where should i store the action?Is there something wrong with that?
anyone have the same experience?

thank you in advance.

This is to little information to give you an answer. The deploy.xml code you describe is just a copy command. Does that command actually work? And if so, how do you deploy it? You use a par file? does that file contain the classes?

Please provide us with more info to try and help you solve your problem

thank you for your instant answer,yes,i zip the process files and action classes into a par file named invention.par. The par file has all the classes in the classes folder which is in the same level with processdefinition.xml.My ant script is as follows:

<target name="build.processes" depends="compile.idap" description="builds the idap processes">
 <mkdir dir="build/invention/classes" />
 <copy todir="build/invention">
 <fileset dir="src/process/invention.par" />
 </copy>
 <copy todir="build/invention/classes">
 <fileset dir="build/classes.idap" includes="idap/process/**" />
 </copy>
 <zip destfile="build/invention.par">
 <fileset dir="build/invention" />
 </zip>
 </target>

is the class realy called idap.process.derived.StoreParticipants ? I've had such an error once when I had a small typo between the real class name and the one in the processdefinition.

thanks,it really just a typo problem.:)
