JavascriptGen error in Handler when ref server [message #893606]

I am getting an error from the compile of a handler. This started with the latest milestone last week. Is this a known issue and is there a workaround for it?

EGL level

Version: 0.8.1.v201206280959-1Ds7rFmiVCcYWyaY3NTPd8hSh

Error

IWN.HtmlGen.9990.e 0/0 Generation Failed
Generation completed for handler com.dougw.test.client.client with 2 errors and 0 warnings.

Generation Error
IWN.JavascriptGen.9998.e 27/913 Exception occurred: java.lang.RuntimeException: java.lang.reflect.InvocationTargetException
IWN.JavascriptGen.9999.e 27/913 Stack Trace: java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

Line in the Handler where the error is occuring

function Send_onClick(event Event in)
call AbstractEchoServer.echo(Request.getValue())
using new HttpProxy("com.dougw.test.server2.Echoer") returning to echo
onException wasError;

end

package com.dougw.test.common;

The definition of the the interface
// interface
interface AbstractEchoServer

function echo(parameterName string in) returns (string);

end

The definition of the server
package com.dougw.test.server2;

import com.dougw.test.common.AbstractEchoServer;

service Echoer implements AbstractEchoServer

function echo(parameter string in) returns (string)
return parameter;
end

end

Hi,

There was an enhancement implemented 378384 that changed the syntax of service invocations. Interfaces are no longer used for service invocations.

There are 2 ways to code your service invocation:
1 use the service as the target:

function Send_onClick(event Event in)
    call Echoer.echo(Request.getValue())
        using new HttpProxy 
        returning to echo
        onException wasError;

end

Create a proxy function:

function Send_onClick(event Event in)
    call AbstractEchoServer.echo(Request.getValue())
        using new HttpProxy 
        returning to echo
        onException wasError;
end
[color=red]library[/color] AbstractEchoServer

    function echo(parameterName string in) returns (string){
        @EGLService{ serviceName="com.dougw.test.server2.Echoer"}
    }
    end

end

regards,
Joe

Thanks. That solved it.

Is there someplace where the mechanisms for calling servers is defined? This seems to be the third change in the process and it is a vital part of the product.

Yes, it is vital. The change means that a developer can use a similar approach to access services or other back-end logic.

Here's a description:
