Hi,

I have run the web services in JOnAS server using RMI concept.

i want to run the web services in JOnAS server using AXIS.

Please help me

Thanx in advance...

I have run the web services in JOnAS server using the following steps.

I have create the web-application directery structure as follows..

interest

|

+-- WEB-INF

|

+-- web.xml

+-- webservices.xml

+-- InterestMapping.xml

|

+-- classes/

||

|+-- org.objectweb.interest.Interest.java

|+-- org.objectweb.interest.InterestImpl.java

|

+-- wsdl/

|

+-- Interest.wsdl

* First of all i written the following java interface.

Interest .java

-

package org.objectweb.interest;

import java.rmi.Remote;

import java.rmi.RemoteException;

public interface Interest extends Remote {

double getCompoundInterest(double principal, double interest, int terms) throws RemoteException;

}

Then i have written implementation class as following....

InterestImpl.java

-

package org.objectweb.interest;

import java.rmi.RemoteException;

public class InterestImpl implements Interest {

public double getCompoundInterest(double principal, double interest,int terms)

throws RemoteException {

double total = principal;

for (int i = 0; i < terms; i++) {

total = total * (1 + interest / 100.0);

}

return total - principal;

}

}

Then compile the both...and then put into the classes/org.objectweb.interest folder and then generate the class file for both...

and then copy following xml file in the WEB-INF dir....

web.xml

-

InterestMapping.xml

<?xml version="1.0"?>

<package-mapping>

Then copy the following wsdl file into WEB-INF/wsdl folder.

Interest.wsdl

</wsdl:service>

</wsdl:definitions>

Final i deploy into the jonas server.

check it by http://<hostname>:9000/interest/InterestPC/InterestPort?JWSDL.

It dhows the wsdl file..

Now web service is redady.... client to invoke this web service as follows..

client to invoke the web services.

I have create the directore structure for the cilent web-application..
