[jira] [Commented] (AXIS2-3618) WSDL2Java produces code that causes javac to fail with "code to large"

Martin Gainty commented on AXIS2-3618:
--------------------------------------

This is not the fault of Axis but the fault of Class.getMethod failure to interrogate code size<=64K

but there is a workaround available:

XSL does blind substitution ..the solution is to extend fromOM to output a Collection ( as seen here )


Original:   
   java.lang.Object object = fromOM(
                                             _returnEnv.getBody().getFirstElement() ,
                                             <xsl:value-of select="$outputtype"/>.class,
                                              getEnvelopeNamespaces(_returnEnv));

New:
   Collection collection_of_object=fromOM_Collection

             _returnEnv.getBody().getFirstElement() ,
             <xsl:value-of select="$outputtype"/>.class,
           getEnvelopeNamespaces(_returnEnv));


<!-- Class.getMethod would need the new Class so we must change messageClass from

 java.lang.reflect.Method m = exceptionClass.getMethod("setFaultMessage",
                                   new java.lang.Class[]{messageClass});

-->


while (collection_of_object.iterator().hasNext())

{

  Object object=collection_of_object.iterator().next().
  Class messageClass =object.getClass();
  java.lang.reflect.Method m = exceptionClass.getMethod("setFaultMessage",
     new java.lang.Class[]{messageClass});

<!-- assume fromOM outputs <objects>

                                                      <object>
                                                     </object>
                                                   </objects>

-->
<xsl:for-each select="objects/object">

   <!-- IF output/param[@location='body']/param) drives each record to be unique
          then we can retain outputparamcount as our counter
          otherwise we could need another counter to make sure each xsl:when test is unique for each    

          object      

-->

             <xsl:when test="$outputparamcount=1" return get

                   <xsl:value-of select="$outputparamshorttype"/>

                  <xsl:value-of select="$outputparampartname"/>((<xsl:value-of select="$outputtype"/>)object);
              </xsl:when>

             <xsl:when test="$outputparamcount=2" return get

                 <xsl:value-of select="$outputparamshorttype"/>

                 <xsl:value-of select="$outputparampartname"/>((<xsl:value-of select="$outputtype"/>)object);
            </xsl:when>
</xsl:for-each>


}  <!-- end when -->


Personally I would prefer to twiddle Class.getMethod but thats part of the JDK so the only solution
is to have fromOM create multiple classes (with identical method names) e.g.

class Object1Class { public void method1, public void method2... };
class Object2Class { public void method1, public void method2...};


Everyone uses toOM and fromOM to generate their XML and then to transform XML to code
so these methods need to be left as is


ToOM_Collection and fromOM_Collection is the only solution that would work

> When generating stubs from a large WSDL document using either the ADB or XMLBeans databindings, the generated code causes javac to fail with the following error
>     [javac] /exit26/home/pcanning/visdk_clients/2.5/axis2-1.3/axis_stubs/src/com/vmware/vim/VimServiceStub.java:3090: code too large
>     [javac]     private void populateFaults() {
>     [javac]                  ^
> FYI: In order to successfully run the Axis2-1.3 stub generator, I had to modify axis2.sh to add -Xmx512M to increase the maximum heap size.
