Hi all,

I'm working with jaxb to create a process definition. I've generated all jp=
dl beans but I've found my self into trouble when I wanted to add an expres=
sion  tag in side script tag.

This is the processdefinition.xml that I need

  | <?xml version=3D"1.0" encoding=3D"UTF-8"?>
  | <process-definition  name=3D"validation_case_2" xmlns=3D"urn:jbpm.org:j=
pdl-3.2">
  |     <description>
  |         Definition to test case 2 where we will have one form
  |     </description>
  |     <event type=3D"process-start"  >
  |         <script >
  |             <expression>
  |                 <![CDATA[
  |                 processDataList =3D new com.package.MyClass1();
  | =

  |                 //ProcessData1
  |                 processData1 =3D new com.package.MyClass2();
  |             </expression>
  |             <variable name=3D"taskDataList" mapped-name=3D"processDataL=
ist"/>
  |         </script>
  |     </event>
  |     <start-state name=3D"process-start" >
  |         <transition to=3D"task-1" ></transition>
  |     </start-state>
  |     .
  |     .
  | =


This is the code and output that I've in order to create the process defini=
tion

  | ProcessDefinition pd =3D new ProcessDefinition();
  | =

  | pd.setName("gaston");
  | pd.getDescriptionOrSwimlaneOrStartState().add("asi la descripcion del p=
roceso");
  | =

  | Event startEvent =3D new Event();
  | startEvent.setType("process-start");
  | =

  | Script startScript =3D new Script();
  | StringBuffer sb =3D new StringBuffer();
  | sb.append("\n\t\t");
  | sb.append("<expression>");
  | sb.append("\n\t\t\t");
  | sb.append("<![CDATA[");
  | sb.append("\n\t\t\t");
  | sb.append("processDataList =3D new com.package.MyClass1();");
  | sb.append("\n\t\t\t");
  | sb.append("processData1 =3D new com.package.MyClass2();");
  | sb.append("\n\t\t\t");
  | sb.append("]]>");
  | sb.append("\n\t\t");
  | sb.append("</expression>");
  | sb.append("\n\t");
  | =

  | String s =3D new String(sb);
  | =

  | startScript.getContent().add(s);
  | =

  | startEvent.getActionOrScriptOrCreateTimer().add(startScript);
  | =

  | pd.getDescriptionOrSwimlaneOrStartState().add(startEvent);
  | =

Output

  | <?xml version=3D"1.0" encoding=3D"UTF-8" standalone=3D"yes"?>
  | <process-definition xmlns=3D"urn:jbpm.org:jpdl-3.2" name=3D"gaston">
  |     <description>asi la descripcion del proceso</description>
  |     <event type=3D"process-start">
  |         <script>
  | 		<expression>
  | 			<![CDATA[
  | 			processDataList =3D new com.package.MyClass1();
  | 			processData1 =3D new com.package.MyClass2();
  | 			]]>
  | 		</expression>
  | 	</script>
  |     </event>
  | </process-definition>

First problem...

It seems that script class does not have an expression tag which I could us=
e so I've add it as string to its content... is this approach correct ?

Second problem...

As you can see I'm facing encoding problems with start and end tag symbol. =
I've tried with other encodings but none of them worked. Does anyone know h=
ow to solve this ? Is the CDATA tag the problem ?

My main concern now is to solve the encoding issue.

Thanks in advance !!!
