Error while deploying ABCS with custom XPATH using AID

Question

Hi All,
I use a custom xpath function as given below in the Provider ABCS BPEL.
<copy>
<from expression="sql:queryToWhereClause(ora:getNodes('xxx','xxxx','xxxxxxxx'))"/>
<to variable="variableName" part="predicate"/>
</copy>
When I deploy this ABCS from jdeveloper, everything works fine.
When I try to deploy the ABCS composite using the AID, it throws this error,
[scac] error: in QueryPersonEbizProvABCSImplProcess.bpel(733): could not resolve xpath function "queryToWhereClause", because function "sql:queryToWhereClause" not registered.
I have dropped the classe into $SOA_HOME/soa/modules/oracle.soa.ext_11.1.1/classes, and it still looks like the AID is not able to locate the class. Am I dropping the classes into the right location, or is it something else that is missing? Any pointers are appreciated.
Thanks
Anish.

Answer 1

Anish,
this comes from the fact that the SOA compilation tools don't include $SOA_HOME/soa/modules/oracle.soa.ext_11.1.1 in the class path, e.g. in $SOA_HOME/bin/ant-sca-compile.xml which is in turn used by AID for compiling composites.
You can work around this by adding the custom classes/libraries to the classpath in $SOA_HOME/bin/ant-sca-compile.xml. Insert the following entry in section '<path id="scac.tasks.class.path">':
<pathelement path="${oracle.home}/soa/modules/oracle.soa.ext_11.1.1/oracle.soa.ext.jar"/>
With that ant-sca-compile.xml and therefore also AID will be aware of your custom xpath function and the compilation error should disappear.
