doCatch returns null
Hi,
tested with camel 2.10.1 and 2.10.2 :
*When I turn the route :*
from("cxf:/myWebService?serviceClass=com.x.MyWebService").routeId("MyRoute")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
exchange.getOut().setBody(new Output());
}});
*into :*
from("cxf:/myWebService?serviceClass=com.x.MyWebService").routeId("MyRoute")
.doTry()
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
throw new IllegalStateException();
}});
.doCatch(IllegalStateException.class)
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
exchange.getOut().setBody(new Output());
}});
.end();
*Then the response body of myWebService is empty.*
Is it possible that my route returns something in a doCatch() ?
Any help would be appreciated

Hi again,
I solved the problem by changing my route to this:
from("cxf:/myWebService?serviceClass=com.x.MyWebService").routeId("MyRoute")
*.recipientList(simple("direct:${header.operationName}"));*
*from("direct:myOperation")*
.doTry()
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
throw new IllegalStateException();
}});
.doCatch(IllegalStateException.class)
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
exchange.getOut().setBody(new Output());
}});
.end();
I think we have a bug here because 'myWebService' has only 1 operation, so
the 'dispatch' step should not be necessary.

Hi,
*1. I added log statements and I enabled the tracing*
from("cxf:/myWebService?serviceClass=com.x.MyWebService").routeId("MyRoute")
.doTry()
.log(LoggingLevel.INFO, "entering doTry")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
throw new IllegalStateException();
}});
.log(LoggingLevel.INFO, "leaving doTry")
.doCatch(IllegalStateException.class)
.log(LoggingLevel.INFO, "entering doCatch")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
exchange.getOut().setBody(new Output());
}});
.log(LoggingLevel.INFO, "leaving doCatch")
.end();
Logs:
Logs.txt <http://camel.465427.n5.nabble.com/file/n5722945/Logs.txt>
In the last trace I can see that my output is the one expected.
Something weird is that
'business.services.transferin.OutputStartIntegrationProcessTransferIn@308a58a5'
is not surrounded by '[' and ']' like in the other traces..
*2. If I change the code to :*
from("cxf:/myWebService?serviceClass=com.x.MyWebService").routeId("MyRoute")
.doTry()
.log(LoggingLevel.INFO, "entering doTry")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
exchange.getOut().setBody(new Output());
}});
.log(LoggingLevel.INFO, "leaving doTry")
.doCatch(IllegalStateException.class)
.log(LoggingLevel.INFO, "entering doCatch")
.log(LoggingLevel.INFO, "leaving doCatch")
.end();
The response is empty.
*3. If I change the code to :*
from("cxf:/myWebService?serviceClass=com.x.MyWebService").routeId("MyRoute")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
exchange.getOut().setBody(new Output());
}});
.doTry()
.log(LoggingLevel.INFO, "entering doTry")
.log(LoggingLevel.INFO, "leaving doTry")
.doCatch(IllegalStateException.class)
.log(LoggingLevel.INFO, "entering doCatch")
.log(LoggingLevel.INFO, "leaving doCatch")
.end();
Then I have my response.
Thank you for your help

Maxence,
I suggest that you try first with a simple camel CXF route
from("cxf:/myWebService?serviceClass=com.x.MyWebService")
.transform(new Output())
.log("Display output : " + new Output());
Remarks :
- What do you return from new Output ?
- CXF dataformat is by default POJO. That means that new Output should
return the objects that JAXB classes (generated by CXF plugin) will use to
send SOAP response to the HTTP client
- Transform processor allows to set the Out response used by camel exchange
Regards,
Charles

Hi
In your code there may be a bug in doCatch I am not sure. Though can
you try adding a extra step after the process in the doCatch.
doCatch(...)
.process( ...)
.to("log:foo") <-- add extra step
.end()
Also see this FAQ about using getOut or getIn
