Re: inline::java problems, newbie question

[Patrick LeBoutillier]

Matthew,

Maybe there is already a program using port 7890 (the default Inline::Java 
port), or
maybe an Inline::Java process is stuck there from a previous failed run 
(unlikely but possible).
Check with the 'netstat' command to see.

If you want you can use the PORT configuration option to set a different 
port
number:

use Inline (
 Java => <<'EOJ',
 public class Hi{
        String greeting;
        public Hi(String greeting){
                this.greeting = greeting;
        }
        public void setGreeting(String newGreeting){
                greeting = newGreeting;
        }
        public String getGreeting(){
                return greeting;
        }
 }
EOJ
PORT => 1234
) ;
my $v = Hi->new("howdy");

Good luck,

Patrick

Hi,

I've just installed inline::java on my Windows 2000 desktop, and am trying 
to run a very basic program, copied pretty much verbatim from an on-line 
tutorial:

use Inline Java => <<'EOJ';
public class Hi
{
        String greeting;
        public Hi(String greeting)
        {
                this.greeting = greeting;
        }
        public void setGreeting(String newGreeting)
        {
                greeting = newGreeting;
        }
        public String getGreeting()
        {
                return greeting;
        }
}
EOJ
my $v = Hi->new("howdy");

When I run this, the following is generated:
Can't exec JVM: open3: Can't call method "close" on an undefined value at 
C:/Perl/lib/IPC/Open3.pm line 338.
at C:/Perl/site/lib/Inline/Java.pm line 411
BEGIN failed--compilation aborted at 
C:\projects\software\library\disc\perl\inline\java\inline_java.pl line 27.
Can't open server socket on port 7890: Address already in use: JVM_Bind

Why is the "Address already in use", and how can I fix this?

Thanks -
Matt P.
