Cool. I'll get MediaWiki set up - cycles are a bit short right now, but
I should have something next week. Any suggestions on a domain name?

Is there anything in particular folks would like to see besides the
documentation? I think it'd be nice to have a FAQ and a How-To section
with some nice sample code (adding Lucene searches to PHP apps is
especially cool).

Cheers,

Yes, I think this would help.=20

Thanks

Yes, I think that's the easiest solution.  I will add
a setting to the web.xml and document that this
setting is used when java cannot read the SystemRoot
environment variable or when the SystemRoot
environment variable is not set.=20

That way users can change it the way they want.

I will also add a System.properties option, syntax:=20

  java -DWindows.SystemDir=3D...

which overrides everything else, including the setting
from the web.xml.  That way your setup program (if you
provide one) can start tomcat with the correct
SystemDir setting and then write out the correct
web.xml for the user.

Thanks Jost

Here is my configuration

Windows XP professional SP2
JDK - 1.4.2_05

I will use the work around for the time being

Hi Bharath,

which JDK and Windows OS version do you use? I do not
understand why some versions of windows require the
SystemDir environment variable. There's no reliable
way to read or set environment variables from java.=20

I have just tested on several systems, including XP
home and win98, none of these need SystemDir.  The
only system that I know of is XP, but this problem
goes away when I install network programs. =20

Maybe it is necessary to set a registry entry which
points to the correct SystemDir.  I will check this.

In JDK1.4 it is hard-coded. The code which does this
(in CGIServlet) looks like this:

try {
  var=3DSystem.getenv("SystemDir");
} catch (Throwable t){}
if(var=3D=3Dnull) var=3D"c:/winnt";

The problem is that Sun has introduced getenv() in JDK
1.2, then deprecated it in 1.4 and then un-deprecated
it in 1.5 and now recommends this to pass the
environment to the sub-process.

In other words there is no reliable way to ask for the
value of SystemDir in java.

I think it is possible to read the registry from
jdk1.4.  But this will not work either if the registry
key (which one?) is missing.

I have re-opened the ticked.


As a workaround please use Apache/Php/PhpJavaBridge
and Tomcat/mod_jk connector. This is described in the
INSTALL instructions and in the README.  This is also
much faster than calling CGI programs or native code
from java.


Regards,
Jost Boekemeier

If it is hardcoded then we should remove that and doc it saying that on
windows the user should set the SystemRoot var

Subject: RE: RE: [Php-java-bridge-users] Re:trouble getting php java
bridge to run under tomcat

I have tried the latest build (php-java-bridge_2.0.8RC1.zip) and still
running into the same problem

Fatal error: php_mod_java(52) system error code: 10106. Could not
connect to server. Have you started the java backend (either a servlet
engine, an application server, JavaBridge.jar or MonoBridge.exe) and set
the java.socketname or java.hosts option?. in
C:\sandboxes\mValent3.0\Tomcat 5.0\webapps\JavaBridge\test.php on line
19

I had cleaned up all my old installations restarted the machine and then
reinstalled it so there is noway that there was a remnant of the old
installation.

Now when I ran test.bat things were fine and could see the java system
properties printed out but when I tried to browse the test.php through
tomcat I ran into the same problem. On a closer look=20
I found that in the case of phpinfo output through test.bat the
SYSTEMROOT
Variable was pointing to C:/Windows (the correct path) but in the later
case
It was pointing to C:/Winnt (a non existent folder on the machine). Are
we
hardcoding this path?

Please find both the outputs attached.

Hi,

please excuse the delay.  I have attached the
corrected JavaBridge.war.  The full download is
called: php-java-bridge_2.0.8RC1.zip.
