[jibx-users] NoClassDefFoundError with optional value

[ivan.gorcsev]

Hi All,

I have the following JiBX binding definition:

     <mapping name="name1" value-style="attribute"
              class="p.a.c.k.a.g.e.ErrorClass"
              extends="p.a.c.k.a.g.e.AbstractClass">
         <structure map-as="p.a.c.k.a.g.e.AbstractClass"/>
         <value name="name2" usage="required"
                get-method="getName2" set-method="setName2"/>
         <value name="name3" usage="optional"
                get-method="isName3" set-method="setName3"
                serializer="p.a.c.k.a.g.e.SerializerClass.name3Serializer"
                deserializer="p.a.c.k.a.g.e.SerializerClass.name3Deserializer"/>
     </mapping>

Which during JiBX compilation produces the following error:


     [bind] Generating code for mapping p.a.c.k.a.g.e.OtherClass
     [bind] Generating code for mapping p.a.c.k.a.g.e.ErrorClass

     [bind]     at org.jibx.binding.ant.CompileTask.execute(CompileTask.java:248)

The JiBX compilation is done through an Ant task:

        <taskdef name="bind" classname="org.jibx.binding.ant.CompileTask"
            classpathref="jibx-classpath"/>

        <bind verbose="true" load="true" binding="jibx-bindings.xml">
            <classpathset dir="classes"/>
            <classpathset file="jarfile.jar"/>
        </bind>

The jibx-classpath definitely contains p.a.c.k.a.g.e.MissingClass, so does jarfile.jar.
p.a.c.k.a.g.e.SerializerClass does not reference to p.a.c.k.a.g.e.MissingClass (at least not in a trivial way, I could not find the link between them, but this is a big system, anything can happen).

The interesting thing is that if I set the usage of name3 to be required instead of optional everything compiles fine.

Can anyone help me what to check or change?

Many thanks,
I.G.
