</tr>
<tr>
<td> <input type="submit" name="submit" value="submit" >

</tr>
</table>
</form>
</body>
</html>

<%
response.setContentType("text/html");
String uname = request.getParameter("username");
String pwd = request.getParameter("password");
if (uname.equals(pwd))
out.print("wel come");
else
out.print("dont come"); %>

and this is my dwrtest.java file


public class dwrtest {
public boolean uValid(String uname)
{

if (uname.equals(""))
return false;
else
return true;
}

}

this is my dwr.xml file

<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN"
"http://www.getahead.ltd.uk/dwr/dwr10.dtd">

<dwr>
<allow>
<create creator="new" javascript="dwrtest">
<param name="uname" value="String"/>
</create>
</allow>
</dwr>

this is web.xml file

<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
</servlet>

<servlet-mapping>
<servlet-name>dwr-invoker</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>

in the code what i am doing is just validating the username field for notnull using dwr concept please can anybody tell me where i am doing the mistake.

ka durgesh,
Javaranch tip:

If you are going to post more than a line or two of your code, wrap that
code in a set of UBB Code tags.
Doing so will help to preserve your code's indenting, making it easier to read.
If it is easier to read, more people will actaully read it and you will
stand a better chance of getting help with your question.
See UseCodeTags for more
help with UBB code tags.
