com.poc.multimodule.ota.common.ActionType is a type generated by ota-common module and is there in generated base-binding.xml I am using.It is part of the schema OTA_SimpleTypes.xsd

ActionType definition in schema file

<xs:simpleType name="ActionType">
    <xs:restriction base="xs:string">
        <xs:enumeration value="Add-Update"/>
        <xs:enumeration value="Cancel"/>
        <xs:enumeration value="Delete"/>
    </xs:restriction>
</xs:simpleType>

What is causing this java.lang.IllegalStateException: Internal error – cannot modify class and how to resolve this?

Thanks,
Jignesh

Jignesh,

The classpath: option is not supported by the maven plugin.
You should use the <includeBaseBindings> param to include a base binding.

I would suggest you take a look at the pre-built opentravel.org schema bindings in the JiBX schema library: http://jibx.sourceforge.net/schema-library/site.html#opentravel.org

You can find projects that build a complete library for the 2010B and 2011A schema. The maven projects are in our source repo at: http://jibx.svn.sourceforge.net/viewvc/jibx/trunk/schema-library/org.opentravel/

You should be able to adapt these projects for use in the 2003B schema.

Good Luck!
