WS-BPEL if and switch statement

[sujoy ray]

Hi!!

I wanna use if and switch statement in my BPEL code.

my code
========

<sequence>
        <assign name="test">
           <copy>
           <from variable="Input" part="assets1"/>
           <to>$tmpVar</to>
           </copy>
        </assign>
</sequence>
<if name="checker">
    <condition>contains($tmpVar,'Power')</condition>
    <then>
    .........This_code_runs_perfectly
    </then>
    <else>
    .........Nothing_to_write
    </else>
</if>

However getting the following error during deployment.

java.lang.IllegalArgumentException: null-argument
       at org.apache.ode.bpel.compiler.BpelCompiler.compile(
BpelCompiler.java:6
87)
       at org.apache.ode.bpel.compiler.IfGenerator.compile(IfGenerator.java
:45)

       at org.apache.ode.bpel.compiler.BpelCompiler$7.run(BpelCompiler.java
:753
)



Even a condition 1=1 is giving the same error.

Secondly, I wish to use switch statement with case condition

<switch>

<case condition ="contains($tmpVar,'Power')">

my_code_runs_here

</case>

</switch>

Can anybody please tell me the right way of writing these two statements?

Best Regards,

Sujoy
