targetNamespace & NameSpace issue

[saipraneeth nallapareddy]

i am a newbie to the web services, i am using axis2, the thing i have made a hand typed wsdl file and rectified all the errors regarding the syntactic and other errors but the one i am unable to rectify is the namespace issue which i am facing for the operation which i have created based on a java program whose main purpose is to tell Hello followed by the parameter passed.

Earlier when i just deployed the service archive(.aar file) only using a services.xml file and the .class file and depending on server generated .wsdl file i'm getting the required result, so i thought of making a wsdl file on my own by going through the tags and the attributes which are inter-related among the other tags and i'm able to finish the wsdl file but i'm stuck at the namespace issue, i have tried to include the same namespace which the server has generated but i have no luck. i know that it will fail how can i figure out the right namespace for my operation that is related to the java method.

here is my wsdl file

  
<?xml version="1.0" encoding="UTF-8"?>

		</wsdl:port>
	</wsdl:service>
</wsdl:definitions>
  

services.xml

 
<service name="TrialService"> 
<description> 
This is my first service, which says hello 
</description> 
<parameter name="ServiceClass">HelloTrial</parameter>
<parameter name="useOriginalwsdl">true</parameter>
<operation name="sayHello"> 
<messageReceiver 
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/> 
</operation>
</service>   

java program

  public class HelloTrial
{
	public String sayHello(String name)
	{
		return "Hello "+name+"!";
	}
}  

now can any one help me to figure out the right namespace for the operation

the errors i got when i have started to generate the stubs from the hand typed wsdl file, there are errors but the stubs have been generated

it is just due to case sensitive issue as i have made it is a hand typed one and i didn't made use of any tools i couldn't locate the error, the only way i have rectified the errors that are pointed when i generate the stubs using wsdl2java.bat.
the error is targetNameSpace should be targetNamespace.
Ofcourse i have modified the WSDL file when compared to the one i posted, they are all pointed by wsdl2java.bat.
