Subject Error Handling In Camel
Date Wed, 31 Aug 2011 08:00:14 GMT
Hi All,

While working with Camel i have a requirement where i need to validate an
XML with a given XSD and in case of validation faliure need to stop the
process and notify user about valdation failed

First part is working fine for the validation as i am using camel out of the
box validator
and i have declared a global Exception handler in my spring.xml file with
the following entry

<onException useOriginalMessage="true">
	    <exception>org.apache.camel.ValidationException</exception>
	    <exception>org.xml.sax.SAXParseException</exception>
	   
<exception>org.apache.camel.processor.validation.SchemaValidationException</exception>
   
	    <exception>java.lang.Exception</exception>
	    <handled>
      		<constant>false</constant>
    	</handled>
	  	<process ref="exceptionHandler"/>
	  	to uri="file://data/failed" /
   </onException>

where exceptionHandler is my custom Exceptionhandler 

public class AdapterExceptionHandler implements Processor {

	IAdapterManager adapterManager;
	
	public void setAdapterManager(IAdapterManager adapterManager) {
		this.adapterManager = adapterManager;
	}

	public void process(Exchange exchange) throws Exception {
		ExceptionBean exeB = new ExceptionBean();		
		System.out.println(exchange.getProperty("************
"+Exchange.EXCEPTION_CAUGHT,Throwable.class));
       	exeB.setExceptionObj(exchange.getException());
		System.out.println("Excahange adapterManager---------"+adapterManager);
		ManagerStateBean mgrStateBean = null;
		if (adapterManager.getAdapterMgrState() != null) {
			mgrStateBean=adapterManager.getAdapterMgrState();
		}else{
			mgrStateBean = new ManagerStateBean();
		}
		mgrStateBean.setExecutionStatus(AdapterConstants.ExceptionOccurred);
		mgrStateBean.setExceptionData(exeB);		
		adapterManager.setAdapterMgrState(mgrStateBean);		
	}

But when validation getting failed camel is giving the control back to
AdapterExceptionHandler but Exchange is coming as null since when i am
trying to fetch exception object from it it is coming as null

though on the console it is showing the DefaultErrorHandler is handling the
exception but i am clueless how i can forward the exception to my
"AdapterExceptionHandler "

here is the console output

[thread #1 - file://data/input/] DefaultValidationErrorHandler  DEBUG
