Problem with HelloWorld

Question

Hello,
I am a new user to BPEL. I understand all the concepts, so I downloaded the latest and greatest dev tools (Jdeveloper) and I am trying to complete the hello world example (http://www.oracle.com/technology/products/ias/bpel/pdf/orabpel-Tutorial1-HelloWorldTutorial.pdf). The first thing I have noticed is that the example is that it is written for us with eclipse in mind, but i figure I can work it out using jdeveloper. I am up to building the example, but I keep getting an error in this line;
concat( “Hello ”, bpws:getVariableData( 'input', 'payload', '/SyncHelloWorldRequest/input' ))
The compiler is giving the following error;
Attribute bpws:getVariableData not defined on element from
Here is the full snippet of code;
<assign name="createReturnStr">
<copy>
<from expression=concat(“Hello ”, bpws:getVariableData('input','payload','/SyncHelloWorldRequest/input' )) />
<to variable="outputVariable" part="payload" query="/client:SynchHelloWorldProcessResponse/client:result"/>
</copy>
</assign>
Any hints or ideas would be appreciated
Regards
Ben

Answer 1

Are you typing the expression your own?
Please look at the namespace prefix,
Oracle BPEL require namespace prefix at the "query"
To correct the error, please change
<from expression=concat(“Hello ”, bpws:getVariableData('input','payload','/SyncHelloWorldRequest/input' )) />
to
<from expression=concat(“Hello ”, bpws:getVariableData('input','payload','/client:SyncHelloWorldRequest/client:input' )) />
