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

  Hi,
   
  I'm newby in PHP and PHP/Java bridge, and I have some doubt about it. It seems that I can not instantiate Java class from PHP in case that class imports some external library, regardless that library is available in jar file that I use. Here is the PHP code:
  ...
  require_once('http://localhost:8080/JavaBridge/java/Java.inc'); 
  java_require("moodleLOCMapper v0.003.jar");
  $repository=new Java("depths.moodle.RepositoryFactory");
  ...
  Java code
  package depths.moodle;
  import org.openrdf.sesame.repository.SesameRepository;
  import depths.moodle.repository.Repository;
  public class RepositoryFactory {
  ...
  And here is the error:
   
  javax.servlet.ServletException: PHP Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: CreateInstance failed: new depths.moodle.RepositoryFactory. Cause: java.lang.ClassNotFoundException: Unresolved external reference: java.lang.NoClassDefFoundError: org/openrdf/sesame/query/QueryEvaluationException. -- Unable to call constructor, see the README section "Java platform issues" for details. VM: 1.6.0_04@http://java.sun.com/" at: 
   
  Did I make some mistake here, or I have to create facade class in order to access this class?
   
  Thanks
  Zoran

The IP is interesting. However, if you want to connect to a back end running on any other
interface than 127.0.0.1, you need to switch on promiscuous mode, even if 192.168.15.62 resolve to
a local address. If you have disabled the loopback interface, please enable it. It is considerably
faster. (In promiscuous mode the bridge switches off named pipe communication, furthermore some OS
switch on Nagle's algorithm if the communication goes through a real network interface).

java_require ("foo.jar") is equivalent to:

  $here=getcwd(); java_require("$here/foo.jar");

Otherwise you must use an absolute path or even a URL, for example:

  java_autoload("file:///c:/foo.jar;http://php-java-bridge.sf.net/baz.jar");



> java_require("http://localhost:8080/JavaBridge/myapp.jar");

Yes, this will work. Since version 4.1.0 the bridge copies
http://localhost:8080/JavaBridge/myapp.jar to file:/{java.io.tempdir}/myapp.jar and rewrites the
URL to use the local file instead.


 
> As I understand it, simply using java_require("myapp.jar") should be able to resolve correctly,

The bridge tries to load myapp.jar from 1) /usr/share/java, 2) from $HOME/lib/ and 3) from
getcwd()/

you will get the same error, if you start PHP from the console. So this is not an issue with
apache or the php/java bridge.

You need to add GNU Gettext, which might be disabled on Windows. -- I have never used PHP on
windows, so I don't know how to resolve this issue. In the worst case you need to compile GNU
Gettext for windows.

Please see the PHP documentation: http://www.php.net/manual/en/ref.gettext.php and the PHP mailing
lists for further help.

yes, this is documented, I think. :)

Isn't it possible to copy all your libraries to WEB-INF/lib?


Basically users should be able to install the bridge with 3 simple steps:

1. Rename JavaBridge.war to myApp.war and add all needed Java and PHP libraries to the
   myApp.war

2. Copy myApp.war to the J2EE autodeploy folder, wait until the directory myApp appears

3. Copy the directory myApp over to the Apache or IIS document root

4. Browse to http://yourHost.com/myApp and run the PHP/Java applications.

the message means that bindtextdomain() is not defined. :)


Please see your PHP documentation for details.
