Hi Fady,
I am a newbie with web services and axis too. But do you need
to use dynamic invocation interface to access this web service?
I can access the web site with stub code generated by WSDL2Java.
Setup:
windows 2000 with lastest service pack
axis-1_2beta
java version "1.4.1_01"
Output:
C:\axis-1_2beta\samples\test>java -classpath .;C:\axis-1_2beta\samples\test;%CLA
SSPATH% Test
log4j:WARN No appenders could be found for logger (org.apache.axis.i18n.ProjectR
esourceBundle).
log4j:WARN Please initialize the log4j system properly.
1:05 PM
Code:
import com.Nanonull.www.TimeService.*;
public class Test {
public static void main(String[] args) throws Exception {
TimeServiceLocator tsl = new TimeServiceLocator();
TimeServiceSoap tss = tsl.getTimeServiceSoap();
System.out.println(tss.getCityTime("London"));
}
}

It works great. On the other hand, when I call another service
'<EM>getCityTime</EM>' that needs a parameter, I get an error message
saying:</FONT></DIV>
