php-java-bridge-users Mailing List for PHP/Java Bridge

do you plan to create a CNI version your natcJavaBridge.c? do you think
it is worth? .. right now I dont have much time to work on that right
now, but I may help if you think that it would be worth to do.. or even
do it myself entirely.. then would just need some help from you..

yes.. the my original code used a lots of space chars as padding.. but
sourceforge's forum engine shrank it to just one space.. thats why the
output length is different... the original class was:

public class Test {

	public String test () {
		StringBuffer sb = new StringBuffer ();

		for (int i=0;i<10000;i++) {
			sb.append (i);
			sb.append ("                     ");
		}
		return sb.toString ();
	}

}



so Test.test() outputs 248890 bytes.

I just checkout the cvs and tried and the same problem comes up again.

now the pattern is a little different though.. the php script runs fine
for like 15 times.. then the same exception comes up in JavaBridge.svr
console.. and the php output is this:

      Warning: java.lang.StringIndexOutOfBoundsException in
/home/www/test.php on line 31

then I can just run the script again and it will work.. for 2 or 3
times.. then the exception and the warning come up again.. and this
pattern is repeated as many time I try the thing.


I compiled with -g so the exception is a bit more verbose:

java.lang.StringIndexOutOfBoundsException
   at java.lang.String.charAt(int) (/usr/lib/libgcj.so.4.0.0)
   at gnu.gcj.convert.Output_8859_1.write(java.lang.String, int, int,

... what this mean exactly? ... apache is multithreaded.. and thus I can
have two php scripts running in different threads and being called at
the same time.. so they cannot access the same class.method? or cannot
use the php-java-bridge lib at once at all?
