Camel throws StackOverflowException while converting message body
Hi there!
A have route:
from("cxf:/CDAMediationService?serviceClass=" +
CDAMediationService.class.getName())
.process(new RequestProcessor())
.log(LoggingLevel.INFO , "Request before
transformation:\n${body}")
.to("xslt:xslt/MediateCDARequest.xslt")
.log(LoggingLevel.INFO , "Request after
transformation:\n${body}")
.process(new HeaderSetterProcessor())
.to("cxf://"+cdaUri+"?serviceClass=" +
Invoke.class.getName())
.wireTap("direct:saveResponse")
.log(LoggingLevel.INFO , "Respone before
transformation:\n${body}")
.to("xslt:xslt/MediateCDAResponse.xslt")
.log(LoggingLevel.INFO , "Response after
transformation:\n${body}")
.process(new ResponseProcessor());
Somewhere between 5th and 7th row it throws StackOverflowException (i
attached log file with stack trace). log.txt
<http://camel.465427.n5.nabble.com/file/n5737854/log.txt>
I need help to solve this problem, or find round way.
P.S. sorry for my english:)

It looks like your body is a "java.util.Scanner" and you try to convert
this into a "java.util.List" what isn't working:
ERROR \--> Previous exception on exchangeId:
ID-vsedykh-nb-54170-1377503204942-0-2
org.apache.camel.TypeConversionException: Error during type conversion from
type: java.util.Scanner to the required type: java.util.List with value
java.util.Scanner[delimiters=,(?!(?:[^\(,]|[^\)],[^\)])+\))][position=0][match
valid=false][need input=false][source closed=false][skipped=false][group
separator=\�][decimal separator=\,][positive prefix=][negative
prefix=\Q-\E][positive suffix=][negative suffix=][NaN
string=\Q?\E][infinity string=\Q?\E] due java.lang.StackOverflowError
Can you enable tracing and check it? Did you hide something from your route?
Best,
Christian

i tried that, it didn't work. There was the same error but in
CxfProducer.class. Code in headerSetterprocessor was copied from CxfProducer
(i explained why in comments in HeaderSetterprocessor).

Some thoughts:
Instead of using your HeaderSetterProcessor, you could do:
from("...")
...
.setHeader(CxfConstants.OPERATION_NAMESPACE, constant("
http://invoker.ps.eos.fairisaac.com"))
.setHeader(CxfConstants.OPERATION_NAME, constant("processRequest"))
.convertBodyTo(YourPayload.class)
...
what is more expressive.
However, in your HeaderSetterProcessor on line 42, you do
List<?> list = exchng.getContext().getTypeConverter().convertTo(List.class,
it);
which is the root cause for this exception:
ERROR \--> Previous exception on exchangeId:
ID-vsedykh-nb-50709-1377338945967-0-2
org.apache.camel.TypeConversionException: Error during type conversion from
type: java.util.Scanner to the required type: java.util.List
It doesn't really fit into the route you shared...
Best,
Christian

I found round way: I replaced camel cxf component call by direct CXF usage in
processor. now it works fine. But i will participate in this case and will
help you (as posible) to understand and fix it.
Thanks,

Re: Camel throws StackOverflowException while converting message
body
Posted by Valery <va...@gmail.com>.
I change my route in way to exclude HeaderSetterprocessor. it looks like
that:
from("cxf:/CDAMediationService?serviceClass=" +
CDAMediationService.class.getName())
.process(new RequestProcessor())
.log(LoggingLevel.INFO, "Request before
transformation:\n${body}")
.to("xslt:xslt/MediateCDARequest.xslt")
.log(LoggingLevel.INFO, "Request after
transformation:\n${body}")
.setHeader(CxfConstants.OPERATION_NAMESPACE).simple("http://invoker.ps.eos.fairisaac.com")
.setHeader(CxfConstants.OPERATION_NAME).simple("processRequest")
//.process(new HeaderSetterProcessor())
.to("cxf://" + cdaUri + "?serviceClass=" +
Invoke.class.getName())
.wireTap("direct:saveResponse")
.log(LoggingLevel.INFO, "Respone before
transformation:\n${body}")
.to("xslt:xslt/MediateCDAResponse.xslt")
.log(LoggingLevel.INFO, "Response after
transformation:\n${body}")
.process(new ResponseProcessor());
But error saved ( stackTrace.log
<http://camel.465427.n5.nabble.com/file/n5737931/stackTrace.log> ). So i
thing problem in CxfProducer class. I wanna try another ws implementation.
What would you recommend?
Best,
Valery

Re: Camel throws StackOverflowException while converting message

There is FaultProcessor.java
<http://camel.465427.n5.nabble.com/file/n5737924/FaultProcessor.java>
And I just tried route with java version 1.7.0_10 - i got the same error, so
problem not in java.

Could you please also share the FaultProcessor.

Ok, I will try older java version and write here about results.
Yes, i use 'onException' definition in global scope:
onException(Exception.class).handled(true).process(new
FaultProcessor());
this string places just before route definition.
Here is my HeaderSetterProcessor.java
<http://camel.465427.n5.nabble.com/file/n5737918/HeaderSetterProcessor.java>
. There I set header options for cxf endpoint and there is code that i found
in camel sources and pasted there because it doesn't work under the hood for
some reasons.
Thank for your participation.
Best,
Valery

Re: Camel throws StackOverflowException while converting message body
Posted by Christian Müller <ch...@gmail.com>.
First of all, Java 1.6.0_20 is really old and some bug fixes behind the
latest one which is 1.6.0_43. Please consider to upgrade...
Do you use an 'onException' definition (route or global scope) to handle
your errors?
Can you please share the HeaderSetterProcessor with us!?
Best

Valery, please have first a look at [1].
We need some more information, if you expect help from us:
- Complete stack trace
- Which Camel version do you use?
- Which java version do you use?
- Later, we are may also interested in the RequestProcessor,
HeaderSetterProcessor or ResponseProcessor...
