Sky Wang updated CAMEL-987:
---------------------------
Component/s: camel-cxf
I think this is a camel-cxf component bug.
> when deal with a response header, an infinite loop occurs
> -----------------------------------------------------------

> Key: CAMEL-987
> URL: https://issues.apache.org/activemq/browse/CAMEL-987
> Project: Apache Camel
> Issue Type: Bug
> Components: camel-cxf
> Affects Versions: 1.4.0
> Environment: operating system: windows 2000
> software platform: apache-camel-1.4.0 + apache-cxf-2.1.1
> Reporter: Sky Wang
> Attachments: camel-context.xml, sre.wsdl

> I use apache-camel-1.4.0 and apache-cxf-2.1.1 in my application.
> My application is a web service application.Which receive a soap header +
> soap body, and then response a soap header + soap body.
> I use WSDLToJava tool to create the java code from wsdl, it creates an
> interface for me as follow:
> @WebService(targetNamespace = "http://com.aspire/";, name =
> "SreServicePortType")
> @XmlSeeAlso({aspire.com.xsd.ObjectFactory.class})
> @SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
> public interface SreServicePortType {
> /*
> *
> */
> @SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
> @WebMethod
> public void serviceContentFetchReq(
> @WebParam(partName = "request", name = "serviceContentFetchReq",
> targetNamespace = "http://com.aspire/xsd";)
> aspire.com.xsd.ServiceContentFetchReq request,
> @WebParam(partName = "requestHeader", name = "serviceHeader",
> targetNamespace = "http://com.aspire/xsd";, header = true)
> aspire.com.xsd.ServiceHeader requestHeader,
> @WebParam(partName = "response", mode = WebParam.Mode.OUT, name =
> "serviceContentFetchReqResponse", targetNamespace = "http://com.aspire/xsd";)
> javax.xml.ws.Holder<aspire.com.xsd.ServiceContentFetchReqResponse>
> response,
> @WebParam(partName = "responseHeader", mode = WebParam.Mode.OUT, name
> = "serviceHeader", targetNamespace = "http://com.aspire/xsd";, header = true)
> javax.xml.ws.Holder<aspire.com.xsd.ServiceHeader> responseHeader
> );
> }
> Then, I implement the routing rules in the xml file:
> <process ref="ipValidateProcessor" />
> <choice>
> <when>
> <!-- First predicate -->
> <el>${in.headers.IP_VALIDATE_RESULT == 'true'}</el>
> <to uri="cxf:bean:serviceEndpoint" />
> <process ref="responseProcessor" />
> </when>
> <otherwise>
> <process ref="invalidIPProcessor" />
> </otherwise>
> </choice>
> In the ipValidateProcessor, I set in.headers.IP_VALIDATE_RESULT = false, so
> the invalidIPProcessor will run.In the invalidIPProcessor, I only need set
> response body and response header.
> I have traced the exchange object in the processor, the exchange.out element
> is null, and the exchange.in element is a CxfMessage object. The
> exchange.in.body element is a MessageContentList object: Object[0] is a
> ServiceContentFetchReq , Object[1] is a ServiceHeader, Object[2] is a
> Holder<T>, Object[3] is a Holder<T>.
> So i put response body into Object[2], and put response header into
> Object[3]:
> org.apache.camel.Message in = exchange.getIn();
> List inBody = (List) in.getBody();
> Holder holderBody = (Holder)inBody.get(2);
> holderBody .value = body;// body is a
> ServiceContentFetchReqResponse object
> Holder holderHeader = (Holder)inBody.get(3);
> holderHeader .value = header;//header is a ServiceHeader object
> But, when I run the application, I got an
> Exception:java.lang.OutOfMemoryError: Java heap space.
> I debuged into program, there is an Infinite Loop occured at the
> org.apache.cxf.jaxws.interceptors.HolderOutInterceptor(72):
> for (int x = 0; x < inObjects.size(); x++) {
> Object o = inObjects.get(x);
> if (o instanceof Holder) {
> outObjects.set(x + 1, o);
> }
> }
> I have traced and found: inObjects == outObjects is true, which leads to an
> Infinite Loop.
