Hi
I'm trying to test my application related to a jca resource adapter I did and a
webservices that use such ra.
In my web services I did:
|
|
| InitialContext context = new InitialContext(CicsConfigHelper
.getJndiProperties());
|
| CdsConnectionFactoryImpl cxFactory = (CdsConnectionFactoryImpl) context
| .lookup("java:/CicsDS");
|
| CdsRecordFactoryImpl recordFactory = (CdsRecordFactoryImpl) cxFactory
.getRecordFactory();
| CdsIndexedRecordImpl input = (CdsIndexedRecordImpl) recordFactory
.createIndexedRecord(CdsIndexedRecord.INPUT);
| input.add(data.toString());
|
| CdsIndexedRecordImpl output = (CdsIndexedRecordImpl) recordFactory
.createIndexedRecord(CdsIndexedRecord.OUTPUT);
|
| CdsConnection connection = (CdsConnection) cxFactory.getConnection();
|
| CdsInteractionSpecImpl ispec = new CdsInteractionSpecImpl(); ispec
.setFunctionName(CdsInteractionSpec.CICS_OPERATION_FUNCTION);
|
| CdsInteractionImpl interaction = (CdsInteractionImpl) connection
.createInteraction();
|
| if (interaction.execute((InteractionSpec) ispec, (Record)input, (Record
)output)) {
|
| message = (String) output.get(CdsIndexedRecord.MESSAGE_FIELD);
|
| } else {
| logger.error("Execute was false");
| }
|
|
But when I call this web services I receive a throwable as follows:
| 13:57:15,159 INFO [STDOUT] java.lang.LinkageError  : loader constraint
violation:
| when resolving method "com.bs.cds.jca.CdsInteractionImpl.execute(Ljavax
/resourc
| e/cci/InteractionSpec;Ljavax/resource/cci/Record;Ljavax/resource/cci/Record
;)Z"
| the class loader (instance of org/jboss/web/tomcat/tc5/WebAppClassLoader)
of the
| current class, com/bs/cics/ws/CicsWSImpl, and the class loader (instance
of org
| /jboss/mx/loading/UnifiedClassLoader3) for resolved class, com/bs/cds/jca
/CdsInt
| eractionImpl, have different Class objects for the type javax/resource/cci
/Inter
| actionSpec used in the signature
|
My web service is inside an ear that comes with an axis1.3.war.
I've tested placing the jar file with my jca classes inside the rar file and
outside, in the server instance lib directory, always with same problem.
The problem occurs when execute method is invoked.
Could some body please tell me how could I solve the problem ?
Thanks in advance
J
