Subject Newbie Axis user converting from Apache Soap
Date Mon, 22 Nov 2004 16:20:50 GMT
Hi everyone,

I've been working with Apache Soap for a while. I'm working with a 
proprietary language on my server called "Synergy DBL". This language 
has a primitive type of "WSDL" which defines compound data types, and 
methods. So I'm generating the "Synergy DBL" server side code myself 
with a complex XSLT transformation.

On the server side, I'm using Java. I've been using XSLT to generate my 
own client classes from this primitive WSDL-type definition. I've been 
generating Apache Soap client code, and it worked well, but the 
performance was a little slow.

Now I'm interested in transforming the Synergy method definitions to 
proper WSDL, and using WSDL2Java to generate the client code. Will Axis 
code be faster?

It should be just a straight XSLT transform. In goes:

<?xml version='1.0'?>
<component name="aspclasses">
  <structure name="Asp_login" size="723">
    <field name="P_company_code" type="alpha" size="3"/>
    <field name="P_logon_id" type="alpha" size="10"/>
    <field name="P_password" type="alpha" size="10"/>
    <field name="R_client_no" type="alpha" size="6"/>
    <field name="R_client_name" type="alpha" size="35"/>
    <field name="R_client_opts" type="alpha" size="10"/>
    <field name="R_error_desc" type="alpha" size="132"/>
    <field name="P_user_id" type="alpha" size="3"/>
    <field name="R_menu_tot" type="integer" size="4"/>
    <field name="R_exposed_desc" type="alpha" size="30" dim="10"/>
    <field name="R_fclasp_app$$" type="alpha" size="10" dim="10"/>
    <field name="R_fclasp_ui$$" type="alpha" size="10" dim="10"/>
    <field name="R_seclv" type="alpha" size="1" dim="10"/>
  </structure>
  <interface name="asp">
    <method name="asp_login" id="asp_login" elb="ELB:ASPLIB">
      <methodresult type="integer" size="4"/>
      <param name="asp_login" type="structure" structureName="Asp_login" 
dir="inout"/>
    </method>
  </interface>
</component>

You can see the correlation easily...

And out comes the following just fine:

</definitions>

(I change the invalid "$" signs (Don't ask!) to "_dr")

When I run WSDL2Java, I get the following Exception:

java.io.IOException: Type {http://lang.java}StringBuffer is referenced 
but not defined.

    at java.lang.Thread.run(Thread.java:534)

Anyone know what this is all about? I'm not referencnig StringBuffer 
anywhere!

Thanks for any help!
