Hi Simon!
First of all, thank you very much for your help.
I have some problems running my application. When I run my isClient.java I
get this exception:
Starting ...

I know that I am missing some refence to getInformationObject and
getAllInformationObject and something is missing in the composite, but I
don't know what it is. My application has a complex estructure but I am
going to try to explain it.
isClient.java is:
****************************************************************************

package Client;

public class isClient {
public static void main(String[] args) throws Exception {
System.out.println("Starting ...");
SCADomain scaDomain = SCADomain.newInstance("Information.composite");
System.out.println("Information.composite ready");
InformationService is = scaDomain.getService(InformationService.class,
"InformationServiceComponent");
InformationObject iobj;
try {
iobj = is.getInformation("c1dee5cd");
System.out.println("Description: " + iobj.getDescription());
System.out.println("Lang: " + iobj.getLang());
System.out.println("Name: " + iobj.getName());;
System.out.println("Protocol: " + iobj.getProtocol());
System.out.println("URL: " + iobj.getURL());
System.out.println("ID: " + iobj.getID());
} catch (ISNotFoundException e1) {
e1.printStackTrace();
}
scaDomain.close();
}
}
