Axis2 exception - NoSuchMethodError

[Lebogang Moshe]

Hi All,

I am having trouble testing a web service client. I have generated java stub classes and callback handlers using the Axis2 code generator plugin for eclipse IDE.

Here is the java code i wrote to test simple validation.

        
        MpesaPaymentsServiceServiceStub stub = new MpesaPaymentsServiceServiceStub();

        ProcessValidation pv = new ProcessValidation();
	ProcessValidationE pve = new ProcessValidationE();
	
	pv.setAccount("V1234567");
	pv.setInvoice("123456");
	pv.setRequestType("Validation");
	
	pve.setProcessValidation(pv);
	
	ProcessValidationResponseE eResp = stub.processValidation(pve); // This line throws the Exception
	
	ProcessValidationResponse resp = eResp.getProcessValidationResponse();

As soon i run this code i get the below exception:

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.commons.httpclient.HttpConnectionManager.getParams()Lorg/apache/commons/httpclient/params/HttpConnectionManagerParams;

Might I add, Im using axis2-1.4.1 and it contains the 'commons-httpclient-3.1.jar' which contains the method 'getParams()'.

Could someone please help on this?

Solved this. The issue was conflicting jars in the classpath.
