Hi! Im not very experienced with using Java on Linux, so I'd like to hear about your recommendation which Java-JDK I should install for compiling and using php-java-bridge on Linux (2.4). Which one do you think will work best / most stable / fastest on Linux? And which one is most tested with php-java-bridge? Is php-java-bridge still beta-software, or can you recommend its use in production enviroments? Thanks! best regards Andreas |

no idea, maybe it#s just compilation of tomcat-servlet failing? That
tripped me already sometimes. ;) (@Jost, wouldn't it make sense to
disable that by default?)
This is my configure without servlet compilation:
---------snipp------------
#! /bin/sh
#
# Created by configure
#'--prefix=/usr/local/php5' \
'./configure' \
'--disable-servlet' \
'--with-java=/usr/lib/j2se/1.4' \
"$@"

I rely on documentation and use a standalone JVM which is connected via
sockets ("Mode 3" iirc)
Have fun,

I'm doing the same. I'm using PHP 5.1RC1 - could that be an issue?

OK, that's what I wanted to use too.
When I get it installed some day ;-)

Using Gentoo with kernel 2.4.31 and grsecurity patch. I tried as said sun, blackdawn and ibm jdks with the same error, and I tried PHP 5.1RC1, 5.0.5 and 4.3.11, allways with the same error. Gentoo compiles every software (except jdk bins...) itself, and I have never had an error like that. The system has 256 MB RAM. best regards Andreas |

Hi Andreas, > 2.4.31 and grsecurity patch. > Gentoo compiles every software (except jdk bins...) there's a known problem with older kernels and older libc versions; due to the transition from Linux threads to NPTL some software doesn't work anymore. On RHEL/Fedora for example it is possible to use export LD_ASSUME_KERNEL=2.4.21 to work around this problem. I think your OS vendor should provide a similar workaround. Anyway, a strace `which javac` test.java 2>strace.log should give some insight. Regards, Jost Boekemeier ___________________________________________________________ Gesendet von Yahoo!

Seems I can't ececut anything from java.

My kernel-version is 2.4.31, with grsecurity patches (PAX...), perhaps
it has something to do with that?
I have never used Java on Linux, so perhaps I'm missing something.
It's strange, I can execute "java", but "javac" gets killed somehow.
