RE: Java not exitting cleanly

Thu, 22 Jan 2004 06:03:01 -0800

Stefan,

A few people have reported this problem and I hope we have found the solution yesterday.

In Java/JVM.pm, around line 213, comment out the line that executes the "kill(15, ...)" function:

                # Inline::Java::debug(1, "Sending 15 signal to JVM...") ;
                # kill(15, $this->{pid}) ;
                Inline::Java::debug(1, "Sending 9 signal to JVM...") ;
                kill(9, $this->{pid}) ;

If you still have problems, try removing the "kill(9, ...)" also.

It seems the Windows JVM is not fond of receiving signals.

Note: Please let me know if this works for you.

I will have this fixed in 0.45.

Thanks,

Patrick

Hello,

I run Inline-java with exactly the same configuration as Alex, and it shows
exactly the same behaviour when testing the build.

Subsequently, I still installed java-inline, and tried to run a test script.
It fails, and prints a lot of messages of which I don't really know the
origin. The printout and script are below. Whether I run the script from the
command line or Apache does not make a difference. Interesting is the fact, that
the error is not deterministic: It occurs either before or after the
execution of the script. In the printout below, the error occurs before the script is
actually executed, thus sending a text file to the browser instead of an
html file (because the "content type" is not the first line). Sometimes it
occurs after, thus printing the correct output of the script, plus the cryptic
error messages attached.

I hope you can do something with these error descriptions.

Stefan

Script:

#!C:\perl\bin\perl
##
print "Content-type: text/html\n\n";
print "<html>";
print "<head>";
print "<title>Sample</title>";
print "</head>";
print "<body>";

print("<p><b>now lets test java</b></p>");
use Inline Java => <<'END' ;
   public class Hello{

      public String helloWorld(){
         return "Hello World";
      }
   }
END

my $obj = new Hello ;
print($obj->helloWorld(), "<br>") ; # prints data

print "</body>";
print "</html>";

Printout:
