Re: Problems running CORBA program with ant

[M. Erik Husby]

The problem is that your really have 4 command line arguments to your program.not two as you have specified.
Put each item in its own <arg>

Thanks for the replies.

The problem appears to be related to the double quotes that ant puts around
my arguments. This is what I got:

The quotes don't show up when I list the arguments from within the program,
but their presence causes the program to fail, even from the command line.
Can I tell ant to omit the quotes?

use ant -v (verbose) to see the exact command that ant is lanching.
copy paste into a shell script and see wat's ur pb.

check if the ORB.init is not a blocking call, it may be that some of ur port
nbrs are still open (when do u shutdown the ORB) ?

seb.

Hello all,

I'm having problems running a simple test program using the

Java 1.4.1_01

implementation on Linux.

The small test program looks like this:

//Test1.java
import org.omg.CosNaming.*;
import org.omg.CORBA.*;
import java.util.*;

public class Test1 {
public static void main(String[] args) {
System.out.print("args: ");
for(int i = 0; i < args.length; i++) {
System.out.print(args[i] + " ");
}
System.out.println("");
try {
ORB orb = ORB.init(args, null);
System.out.println("Initialized orb");
String[] services = orb.list_initial_services();
System.out.println("Got list of services:");
for(int i = 0; i < services.length; i++) {
System.out.println(" " + services[i]);
}
} catch(Exception e) {
System.out.println("Exception thrown " + e);
}
}
}

All this is doing is listing the initial services available

when the orb is

started.

When I run this from the command line using:
java Test1 -ORBInitialHost spoonrest -ORBInitialPort 12345
I get:
args: -ORBInitialHost spoonrest -ORBInitialPort 12345
Initialized orb
Got list of services:
ServerActivator
ServerLocator
NameService
InitialNameService
ServerRepository
TNameService
RootPOA
CodecFactory
DynAnyFactory
POACurrent
PICurrent

Everythink works OK. But, when I use the following Ant task:
<target name="test1">
<echo message="Using -ORBInitialHost ${cosname.host}"/>
<echo message="Using -ORBInitialPort ${cosname.port}"/>
<java fork="true" classname="Test1">
<classpath refid="run.classpath"/>
<arg value="-ORBInitialHost ${cosname.host}"/>
<arg value="-ORBInitialPort ${cosname.port}"/>
</java>
</target>

I get:
Buildfile: build.xml

test1:
[echo] Using -ORBInitialHost spoonrest
[echo] Using -ORBInitialPort 12345
[java] args: -ORBInitialHost spoonrest -ORBInitialPort 12345
[java] Initialized orb
[java] Exception thrown org.omg.CORBA.COMM_FAILURE:

vmcid: SUN minor

code: 201 completed: No

BUILD SUCCESSFUL

Total time: 3 seconds

You can see that the program is getting the command line

arguments from Ant

correctly. The Ant properties appear to be set up

correctly. Does anyone

have any idea why this doesn't work?

Thanks in advance for the help.
