I have created a CXF webservice and exposed it with camel. The webservice is
code first (JSR-181) annotated Java class, springed up in my application
context.
The class looks like this:
@WebService(name="DataExport", serviceName="DataExport",
targetNamespace="com.somecompany.dataexport.v1")
public class DataExport {
public String fetchVesselRegisterV1(@WebParam(name="input") SIInput
input) {
return "";
}
}
I understand that the return statement is never called as camel-cxf
intercepts the message on return (?). At least in a debugger it never stops
there.
My Spring config is like this:
<cxf:cxfEndpoint id="export-webservice" address="/DataExport"
serviceClass="com.somecompany.si.integration.data.export.DataExport">
<cxf:properties>
<entry key="dataFormat" value="POJO"/>
</cxf:properties>
</cxf:cxfEndpoint>
My Route is Java DSL with spring:
...
from("cxf:bean:export-webservice?dataFormat=POJO")//
.routeId("DataExportWSRoute")//
.to("bean:com.somecompany.si.integration.data.export.ExportWSProcessor");
...
The handling bean correctly picks up the data when the webservice is called,
and I am able to read input parameters sent to the WS. However things go
wrong in Websphere after I push my reply (just a Base64 encoded String)
into the exchange: exchng.getOut().setBody(encodedXML);
I get the following exception:
2013-01-23 20:33:35,585 WARN WebContainer : 0
