Re: openwire CSharpGeneratorTask fails to create C# classes from java src

[dougly <dm...@gmail.com>]

Hello,
I don't know if you figure out the solution or not. So here is what my fix
for your issue:



> /**
> * @openwire:marshaller code="9"
> */
> public class Person implements Serializable
> {
>     private String firstName;
>     
>     private String lastName;
>     
>     public void setFirstName(String fn)
>     {
>         this.firstName = fn;
>     }
>     
>     public void setLastName(String ln)
>     {
>         this.lastName = ln;
>     }
>     
>     /**
>     * @openwire:property
>     */
>     public String getFirstName()
>     {
>         return this.firstName;
>     }
>     
>     /**
>     * @openwire:property
>     */
>     public String getLastName()
>     {
>         return this.lastName;
>     }
> }

But I still get the same error though. Did you finally make this to work?
Thanks
