Hi everyone,
Working with Camel-CXF Client endpoint I identified an issue which I cannot
bypass without building custom CXF interceptor.
Camel / Camel-Cxf version: 2.15.1.redhat-620133
CXF version: 3.0.4.redhat-620133
Scenario:
1. Camel-CXF endpoint: dataFormat=POJO
2. WS SEI method in Java:
-----------------------------------------------
public void performOperation(
@WebParam(name = "inParam1", targetNamespace = "http://foo.com";)
String inParam1,
@WebParam(name = "inParam2", targetNamespace = "http://foo.com";)
String inParam2,
@WebParam(mode = WebParam.Mode.OUT, name = "outParam",
targetNamespace = "http://tempuri.org/ODM_WS/Documents";)
javax.xml.ws.Holder<String> outParam
);
note: OUT parameter is the last.
Issue:
- When Camel message body (either MessageContentsList or Object[] ) has 3
elements for all 3 parts
then
org.apache.camel.component.cxf.CxfProducer throws exception when prepare
message to CXF
java.lang.IllegalArgumentException: Get the wrong parameter size to invoke
the out service, Expect size 2, Parameter size 3. Please check if the
message body matches the CXFEndpoint POJO Dataformat request.

org.apache.camel.component.cxf.CxfProducer.process(CxfProducer.java:116)
- When Camel message body has two parts onli for IN and INOUT parameters
CxfProducer is happy :),
but CXF org.apache.cxf.jaxws.interceptors.HolderInInterceptor is not :(
when it processes received response and tries to set values back to the
holders exception is:
java.lang.IndexOutOfBoundsException: Index: 3, Size: 3
at java.util.ArrayList.rangeCheck(ArrayList.java:635)
at java.util.ArrayList.get(ArrayList.java:411)
at
org.apache.cxf.jaxws.interceptors.HolderInInterceptor.handleMessage(HolderInInterceptor.java:67)
---------------------------------------------
Issue is definitelly in Camel CxfProducer.
When it checks parameters and build placeholders for them to pass to CXF -
only input message parts counted:
org.apache.camel.component.cxf.CxfProducer line 246:
int experctMessagePartsSize = boi.getInput().getMessageParts().size();
but guys... there are out parts for holders in boi.getOutput() as well and
CXF expects them...
---
as workaround I was able to plug CXF interceptor and add lost placeholders
to CXF message.
