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

Hi,

another issue came up. If I'm using the bridge as said in last email, I'm=20
getting following error randomly. I can reproduce that error by simply=20
reloading a page a couple of times. That's all on port 8080, so nothing=20
unusual. I could work around that by copying or linking the cgi directory=20
from the JavaBridge webapp to all others, but it would be inconvenient (and=
 I=20
think symlinks don't work - that could make it a space consumer as well).

javax.servlet.ServletException: An IO exception occured. Probably php was n=
ot=20
installed as "/usr/bin/php-cgi" or "c:/php5/php-cgi.exe"
 or "/jsmsc/srv/tomcat/webapps/ROOT/WEB-INF/cgi/php-cgi-i386-linux[.sh]|
[.exe]".
Please see "php_exec" in your WEB-INF/web.xml and WEB-INF/cgi/README for=20
details.
        php.java.servlet.PhpCGIServlet.doGet(PhpCGIServlet.java:466)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

If you could point me to a solution for this issue, I'd be more than happy.=
=20
While I could somehow life with the ssl issue described in my last email,=20
this is a killer. After the error occuring it doesn't work again (so, once=
=20
the error occured it will always occur).

Cheers

Yes, that is possible. And it sounds like an elegant solution

And it works. Sometimes :|

I'm not really sure what's happening there. As said before, I'm trying to r=
un=20
php within tomcat without apache (or any other webserver being involved). I=
'm=20
using JavaBridge.jar and php_servlet.jar in shared/libs with JavaBridge.war=
=20
in webapps (which works just fine). conf/web.xml contains only what's advic=
ed=20
on the website, conf/web.xml within JavaBridge is unchanged and=20
php-cgi-i386-linux.ini in /webapps/JavaBridge/WEB-INF/cgi/ was modified to=
=20
the above.

Now, after tomcat restart, it sometimes works and sometimes doesn't. I'm=20
testing my configuration with /root.php in /ROOT/, I'm=20
using /JavaBridge/test.php for testing JavaBridge in general.

If I restart tomcat and access https://localhost:8443/root.php I'm getting =
an=20
error telling me that php-cgi couldn't be found in /usr/bin (which is true,=
=20
it doesn't exist). If I restart tomcat and access=20
http://localhost:8080/root.php it works fine.

If I access 8443/root.php after restart and it fails, I won't be able to ca=
ll=20
8080/root.php as well without getting an error. However, If I first call=20
8443/root.php, then 8080/JavaBridge/test.php and then again 8443/root.php, =
it=20
works. Sometimes that is - sometimes it doesn't at all.

I don't seem to be able to find any rule behind that. I however tested it a=
=20
couple of times and it looks like this: if 8443/root.php gets called first,=
=20
then I've to call 8080/JavaBridge/test.php and afterwards 8080/root.php=20
before 8443/root.php works. If I don't call the two scripts in that order, =
I=20
won't get 8443/root.php to work without restarting tomcat.

Oh, root.php looks like this:
<?php
	$s =3D java_session(); //to verify I can access those methods
	phpinfo();
?>
(so nothing special in there - I however didn't test taking the java_sessio=
n()=20
away)

I can imagine that you guys are putting an incredible amount of work into t=
his=20
project - let me say that it's greatly appreciated. It would be very helpfu=
l=20
though, if you could extend the descriptions on the website so that they ar=
e=20
easier to follow :-)

Sorry for this long email - I'm uncertain if this is a bug in JavaBridge or=
 a=20
misconfiguration on my end and thought that if the first is true, you might=
=20
need a detailed report.

Best regards
flim

Hi,

please excuse the delay.

It cannot use SSL, no. Isn't it possible to use a
dedicated HTTP port for the PHP<-->JAVA communication?

For example the following entry in the tomcat
server.xml should solve this:

[...]
<Service name="Catalina">
[...]
<!-- Used by local PHP clients -->
<Connector port="7777" address="127.0.0.1"/>
[...]

The php.ini entry would look like:

extension=java.so
[java]
java.hosts=127.0.0.1:7777
java.servlet=On


The 127.0.0.1 makes the 7777 port accessible to the
local host only, it is not even visible from the
internet.

Jost Boekemeier

Hi,

[bridge back-end terminates after the first request,
when running in the IIS container]

I could not reproduce this problem until I saw
"java.exe" in the subject.

On windows the "java.exe" requires a console. Please
use "javaw.exe" instead, which detaches from the
console.

What happened is that java crashed after it tried to
write to the closed OutputStream inherited from IIS
container.


Javaw.exe runs fine within the IIS container. However,
I suggest to use a dedicated container, for example
Tomcat.


Regards,
Jost Boekemeier
