Invoke any operation from inside a webmethod

Question

I think it is a easy problem but I can't solve it:
<br>
<p>
I like to generate with JWS a WSDL-file:
<br><p>
----------ANT Snip ----------------------<br>
<target name="build-service"><br>
<jwsc srcdir="${basedir}../../" destdir="../../output/${ear.deployed.name}"><br>
<jws file="/${packageName}/${javaClassName}"/><br>
</jwsc><br>
</target><br>
<br>
---------------------------------------<br>
<br><p>
I don't like to use user defined Types her. I want only invoke any operation from my Web Service Method if it is invoked.
<br>
My actually not worked code snip:
<br>
---------------------------------------------------<br>
<br>
..........................<br>
<br>
@WebService(name="anyPortType",<br>
serviceName="anyService",<br>
targetNamespace="http://example.org" )<br>
<br>
@SOAPBinding(style=SOAPBinding.Style.RPC,<br>
use=SOAPBinding.Use.LITERAL)<br>
<br>
@WLHttpTransport(portName="commuPort",<br>
contextPath="anyclient",<br>
serviceUri="anyclientimpl")<br>
<br>
public class HelloWorldImpl {  
<p>
@WebMethod(operationName="persistMyData")<br>
public void invokeAnyMethod(com.any.AnyClass aClass){<br>
// invokeAnyMethod may persists Data or any thing else ....<br>
// notice: a user defined type "AnyClass" do not produce errors<br>
<b>Tools.invokeAnyMethod(aClass); <-- localized problem </b><br>
<br>
<br> <p>
..................................... <br>
<br>
} <br>
<br>
But it produce following compling-errors: <br>
<br>
C:\..\build.xml:54: Compile failed; see the compiler error output for details.

Can somebody help me please? It needs a simple solution I think.

Hi Peter,
From the example in MSDN, It means when you  declare a variable within a try or catch block, the variable is instantiated upon entrance to the block and marked for fear-down as the logic exits the block.This means any variables declared within a try
block will only be visible in the try block and not outside of it- like in the catch block.
The following links will help you understand more.

>> I think putting a "return" in the catch block above may make the compiler error go away. 
No, the return statement terminates execution of the method in which it appears and returns control to the calling method. If the method is a
void type, the return statement can be omitted. The best way is Declare your variables before the try block.
