Exception thrown after json schema validation failed

[victo...@gmail.com]

Hi,

We have been testing json schema validation and found membrane throws the following exception if JSON schema failed to validate. It seems the JsonFactory used in membrane doesn't support the createJsonGenerator methods any more. Is this a bug and how do we fix it? Thanks in advance...

Uncaught service() exception thrown by servlet membrane: java.lang.NoSuchMethodError: org/codehaus/jackson/JsonFactory.createJsonGenerator(Ljava/io/OutputStream;)Lorg/codehaus/jackson/JsonGenerator;

Hi Victor.

Which version of Membrane Service Proxy are you using?

Thanks, Tobias

I'm using the latest 4.0.18.

thanks again...

Hi Victor,
are you using IBM WebSphere as a Container for Membrane? Maybe the application server is putting an own version of the JSON lib into the classpath. You can try your config with a standalone Membrane installation to verify that. Maybe you can setup your application server to use the right lig.

Cheers,
Thomas
