Getting NoSuchMethodError !!

34 Views

Hi

Group,

I am trying to access webservice through the PDK. For that , I have created a portal service so that other iViews ( Portal Component) can use.

Following is the set up of my environment ...

PDK : tomcat_pdk_5_0_5_0.zip

JDK : 1.13

Tomcat : 3.3.1a

Axis Client : 1.0

Development Environment : Eclipse 2.1.1

The axis api allows you to publish web services as well as allows you to consume web services.The reason for using axis is that I already have the web service client part written and running under weblogic for some other application. I want to migrate the same code ( only web service invocation part since it is generic enough) to PDK and use to render some iViews by using the portal service.

I have turned on full debug under axis so that I can where exactly it is throwing an exception. The exception is raised beacause it cannot find a SAX Parser in the classpath. I already have included the xerces.jar file in the .par portal service file. I have included in the .par file all the

.jar file which is required since I am also running the same under weblogic. The question is , Is the xerces.jar (in .par portal service) in the classpath or Is there an older version of SAX parser in the class path or Is there a different way to include third pary .jar files in PDK ????

One more thing, the exception is raised after the web service has been called properly and data is also returned since I can see the response XML being written to the axis client log file. The exception is raised when axis client tries to get an SAX parser for parsing the web service response xml.

The Exception is ...
