how to properly suppress WARNs for webfaults

maxvar Dec 2, 2011 2:29 AM

The service we provide starts from a cxfendpoint in POJO mode and routes to one of several implementations based on operation called.

We catch SqlExceptions thrown from an ibatis component being used and handle them with onError, preparing custom faults or rethrowing if an SqlException is an unexpected one.

The WS properly responds to a client with faults, but a WARN is also logged for every such fault.

How should we suppress the warnings for our known "custom" faults, still logging warnings for other faults (caused by unhandled exceptions)?

Or do we probably handle them badly in the first place?

The details are below.

We use cxf 2.3.3 and camel 2.6.0.

The endpoint configured in beans.xml:

<ccxf:cxfEndpoint id="DocsService"

address="http://$:$/Docs"

serviceClass="ru.alfastrah.interplat4.docs.Docs" xmlns:ws="http://alfastrah.ru/interplat4/as4sap/docs">

The part of the route:

from("cxf:bean:DocsService")

.process(new Processor() {

@Override

public void process(Exchange exchange) throws Exception {

MessageContentsList mcl = exchange.getIn().getBody(MessageContentsList.class);

exchange.getIn().setBody(mcl.get(0));

}

})

.choice()

.when(header(CxfConstants.OPERATION_NAME).isEqualTo("GetUnprocessedContractDocumentCards")).to("direct:getUnprocessedContractDocumentCards")

.when(header(CxfConstants.OPERATION_NAME).isEqualTo("ConfirmContractDocumentCard")).to("direct:ConfirmContractDocumentCard")

.when(header(CxfConstants.OPERATION_NAME).isEqualTo("ReturnContractDocumentCard")).to("direct:ReturnContractDocumentCard")

.otherwise().throwException(new Exception("Invalid Operation"));

...

from("direct:ConfirmContractDocumentCard")

.process(new prepParmsForStatusChangeProcessor())

.to("ibLanDocs:confirmCard?statementType=Update")

.process(new prepResultOfStatusChangeProcessor());

The handler:

onException(SQLException.class).handled(true).process(new Processor() {

@Override

public void process(Exchange exchange) throws Exception {

SQLException se = exchange.getProperty(

Exchange.EXCEPTION_CAUGHT, SQLException.class);

if (se.getErrorCode() == 20000) {

CardNotFoundException f = new CardNotFoundException();

exchange.getOut().setFault(true);

exchange.getOut().setBody(f);

} else if (se.getErrorCode() == 20001) {

CardSameStatusFaultBean fb = new CardSameStatusFaultBean();

CardSameStatusException f = new CardSameStatusException("some message", fb);

exchange.getOut().setFault(true);

exchange.getOut().setBody(f);

} else if (se.getErrorCode() == 20002) {

CardArchivedException f = new CardArchivedException();

exchange.getOut().setFault(true);

exchange.getOut().setBody(f);

} else {

throw se;

}

});

What I get in warnings is:
