Re: Importing packages

[Paulo Sérgio]

Patrick, thanks for your attention...
Your advice didn't work...you can see it by yourself in 
http://ese.cos.ufrj.br:8081/axis/Soma6.jws (Soma = sum in portuguese ;) 
), here is the code again:

import org.apache.axis.client.Service;
import org.apache.axis.client.Call;
import java.rmi.RemoteException;
              
public class Soma6 {
       public int soma(int valor1){
               String local = "http://ese.cos.ufrj.br:8081/axis/Soma.jws";;
               Call call = (Call) new Service().createCall();
               call.setTargetEndpointAddress(local);
               call.setOperationName("soma");
               Object[] param = new Object[]{new Integer(valor1), 
Integer(6)};
               Integer ret = (Integer)call.invoke(param);
               return ret.intValue();
       }
}

Like i said before, it's just a test. The reason for call a service with 
other service is that im trying to create a "service configurator",
in that, user will be able to configure an existing service (that can be 
in anywhere in internet) chosing all parameters that he want to use 
and/or default values to parameters,
and it will generate the java code to put behind axis (automagically 
with it's WSDL :) ).
In this test that im trying to do,  i've configured the service sum 
generating sum6 (chosing one parameter, and defining a fixed value (6) 
for the other).

So, can anyone help?

Do you really need to have a web service calling another web service directly?
This adds more things to consider (exceptions to handle, as you've found).
You can easily add
import java.rmi.RemoteException;
To Sum6.jws
But wouldn't it be easier to have the Sum class in a .jar in the web 
application lib directory, and import that class for all the web services that 
need to call it internally. This way there's only one web service call, and 
it's come from the external client?
Just a thought: hope this helps,
Patrick
p.s. you also need to change the return statement to return ret.intValue();

Subject: Importing packages

Hi all, im new to the list (and to axis too) and i have one question to 
start... 

I`ve published the following service just for test and all went well 
(Sum.jws): 

public class Sum { 
  public int sum(int valor1, int valor2) { 
     return valor1 + valor2; 
  } 
} 

Now i want to publish another service that uses the one above, here is the 
code (Sum6.jws): 

import org.apache.axis.client.Service; 
import org.apache.axis.client.Call; 

public class Sum6 { 
	public int sum(int valor1) 
	{ 
		String local = "http://localhost:8081/axis/Sum.jws";; 
		Call call = (Call) new Service().createCall(); 
		call.setTargetEndpointAddress(local); 
		call.setOperationName("sum"); 
		Object[] param = new Object[]{new Integer(valor1), Integer(6)} 
		Integer ret = (Integer)call.invoke(param); 
		return ret; 
	} 
} 

...and i've got the following from axis (while generating wsdl): 

AXIS error 

Sorry, something seems to have gone wrong... here are the details:

ps: i've put axis.jar file in 
/usr/local/jakarta-tomcat-4.1.27/webapps/axis/WEB-INF/classes/ directory for 
the imports, right? 

Any help will be REALLY appreciated :)
