NoClassDefFound:ValidationConfigurationBuilder

[DevNi]

@fge
I am using json-schema-validator 2.2.5 version for which I used the following dependency:

com.github.fge json-schema-validator 2.2.5

But when I run a simple code I am getting the following error,

Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.github.fge.jsonschema.cfg.ValidationConfigurationBuilder at com.github.fge.jsonschema.cfg.ValidationConfiguration.newBuilder(ValidationConfiguration.java:92) at com.github.fge.jsonschema.cfg.ValidationConfiguration.byDefault(ValidationConfiguration.java:102) at com.github.fge.jsonschema.main.JsonSchemaFactoryBuilder.(JsonSchemaFactoryBuilder.java:68) at com.github.fge.jsonschema.main.JsonSchemaFactory.newBuilder(JsonSchemaFactory.java:123) at com.github.fge.jsonschema.main.JsonSchemaFactory.byDefault(JsonSchemaFactory.java:113)

Please help me with this

Thanks,
DevNi

I too got the same error any clues?

[javadev686]

Same error for me too. Please help

OK, 2.2.6 is out but it does not change anything in this regard.

Can you please post the full stack trace? From what is mentioned in this SO comment, it is probable that you have a cause for this exception and that this cause highlights the real problem.

Also, @DevNi @rajesh2win @javadev686 : I know for @javadev686 via SO, but do you all use Weblogic as well?

I had similar problem on Weblogic 12.1.3.0.0 with 2.2.5 json-schema-validator version. After adding

<prefer-application-packages>
            <package-name>javax.ws.rs.*</package-name>
            <package-name>org.joda.time.*</package-name>
            <package-name>org.apache.commons.lang.*</package-name>
            <package-name>com.sun.jersey.*</package-name>
            <package-name>org.glassfish.jersey.*</package-name>
</prefer-application-packages>

to my weblogic.xml problem disappeared.
