Hi, i need some help very badly. I wrote this class to make a web service out of it.
I deployed it on Tomcat server using Axis 1.1. But it does not get deployed -
(cannot see the wsdl and i cannot view it using the axis servlet. But the service
is there in the server-config file. but does not have a log file.)
Can somebody give me a solution?
the service is this.

package project.ws2;
import java.io.*;
public class Batk {


public String kk() {

Runtime r = Runtime.getRuntime();
Process p = null;
String temp="";
try {
p = r.exec("C:\\b.bat");

InputStream i=p.getInputStream();
int data;


while ( ( data=i.read() ) != -1 )

{temp += (char) data;
}//while

i.close();
System.out.println(temp);


}//try


catch (Exception e ) {
System.out.println("Error executing notepad.");
}//catch

return temp;
}//kbat

}//class

One question i forgot to ask was how i could do that.
Here's how i did it....
Once i deployed the the service to the server i invoked the client and tried to view the soap messages passing - But did not see any message flowing.
Please advice me.

hi , i'm new to j2me and wireless programming and i need some help! Pity me if the question sounds silly.
I have a web service which i access from a midp client using the j2me wireless toolkit 1.4 along with ksoap and kxml libraries files. suppose you have this service published in a web site and you can invoke it using a jsp client. In a similar fashion how can i invoke this service from the web site using a j2me simulator?(having a midp client) (what i mean is how can i login to the web site and invoke it using a j2me simulator?)
how should i use a markup language to solve this. If i'm using WML what is the link it has with midlets.
awaiting for a kind reply
Thanx in advance

Hi,
I have a jsp from which i'm trying to call a class called FindBusinessExample.class when a value is passed through the jsp.( finds the defined name from the uddi test registry.)But i get the following exception. Can somebody help???//
The package structure for the class file is - tkv.tris.
the FindBusinessExample.class works fine when it is run from the command line. But gives the following error when referenced from a jsp.(could it be due to the package name that i'm importing in the class)
(I have included the uddi4j.jar in the WEB-INF/LIB as well)
