It looks like your getters is returning this.barcode and your setter is
setting this.myValue
I'm guessing this could be the problem.

Hi,
I got a little struts app that works fine on my or any other pc -
But it's supposed to be running on a little bar code scanner similar to
a palm or so.
As you might have guessed, I am using the application to enter bar
codes.
The scanner is running on Windows CE and there is a little application
running
that submits the scanned bar codes to any application currently running.
In the case my struts application, it's running on a special Windows CE
Version
of Internet Explorer, supporting Javascript. When I am on the first
page
of my struts app, consisting of a little text input form field,
When I scan a bar code, the scanner automatically sends a submit,
and I guess it does so using Javascript?
Anyway - the problem is when doing so, the
"setMyValue()" methode is called correctly,
however, for some weird reason when calling the getter method
in my servlet, it returns NULL!
Sample code:
My JSP:
<html:form action="/myAction" focus="myValue">
<html:text property="myValue" size="14" maxlength="13" />
<html:submit property="action" value="Submit" />
<html:submit property="action" value="Abort" />
</html:form>
My Bean:
public String getMyValue() {
System.out.println("Get MyValue: "+ myValue); // returns NULL
return this.barcode;
}
public void setMyValue ( String myValue) {
System.out.println("My MyValue: "+ myValue); // Returns myValue
this.myValue = myValue;
this.myValue = this.myValue.trim();
}
My Action:
public ActionForward execute( ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response ){
MyBean myBean = (MyBean)form;
String myValue = myBean.getMyValue();
System.out.println("MyValue: "+ myValue); // Returns NULL
Any idea, whats wrong?
Thanks,
Marcus
