you can only convert Java libraries which do not
depend on external libraries.


Please either use the low-level interface, i.e.

java_require("foo.jar;bar.jar");
new Java("com.Foo", "FOO");

instead of

require_once("foo/com_Foo.php");
...
new com_Foo("FOO"),


or copy all external references into the jar file
which should be converted.

Hi,

please copy the mysql.jar and the other jars it
depends on to java.ext.dirs and re-start the bridge
back-end. This will solve this problem immediately.

I will look at this problem.

Hi,

now I am confused. Do you get this message when trying
to connect from php to the PhpJavaServlet or to the
PhpCGIServlet or do you get this message after the
successful connection?

Hi Peter,

first of all thank you very much for this problem
report. Indeed, override redirect (which stops the
secure channel and opens a new socket connection to
8080 to obtain the session handle when java_session()
is not the first java statement in a script) doesn't
work anymore in 3.1.8. The reason is that it now needs
a security token which has been destroyed after the
first Java() statement.

The pure PHP implementation of the PHP/Java Bridge
code doesn't implement override redirect, so this
feature isn't portable anyway.

Please use java_session() as the first Java()
statement in a script, for example:

<?
...
$session = java_session();
$ob = new Java(...);
?>


Since the handle is cached, the following will also
work:

<?
java_session();
$ob=new Java(...);
$session = java_session();

?>


However, I will make a patch available which fixes
this problem. 

Regards,
Jost Boekemeier

Hi Matthias,

[please excuse the delay]

Can you please open a problem report (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)
and attach the relevant tomcat log there?


> With use of java.java, etc. it works.

It's faster and more secure. And it should work with
any J2EE server or servlet engine, that's why I am
very surprised that it doesn't work with one tomcat
version. I think the tomcat log should reveil the
reason.

Jost Boekemeier

It wraps the original exception (jsr223 demands it).
Doesn't $exception->getCause() reveal the original
exception?
