Moodle@ClassLoader1 is not assignment compatible with Moodle@ClassLoader2. In other words, you
have more than one such library in your class path(s). 

Please see our class loading FAQ for details.

Hi,
   
  I have the problem to create an instance of my class ProjectFactory which constructor has the argument of the type org.openrdf.sesame.repository.local.LocalRepository.
  
I'm always gets an error when trying to create this class with the following code:
   
  $projectFact=new Java("depths.moodle.ProjectsFactory",$sesame); 
   
  The error implies that I have provided illegal argument:
   
  Exception occured; mixed trace: java.lang.Exception: CreateInstance failed: new depths.moodle.ProjectsFactory((o:LocalRepository)[o:LocalRepository]).

it seems that this is not an instance of this class.
  Can you give me any suggestions?

Be a better friend, newshound, and know-it-all with Yahoo! Mobile.  Try it now.

To all:

I'm using:
    php bridge: 5.1.2
    java: jdk1.6.0_02
    php: 5.2.5

Here's my question i'm trying to figure out the best way to deal with
errors from the php side throw from java.

Here's an example:

Java:

public class Test{

       public Test(String yippie) Throws Exception
       {
              if(yippie)
              {
                  ex = new Exception("This is an exception thrown from java");
                  System.out.println("Exception: " + ex.getMessage());
                  throw ex;
              }
       }
}


PHP:

try{
  $email_address_obj = new Java("type.Test", $email_address);
  return $email_address_obj;
} catch (JavaException $ex)
{
  echo "Cause: ".$ex->getCause()."\n";
  echo "Message: ".(string) $ex->getMessage()."\n";
}


Trouble:

My issue is, I want to out the message Exception was instantiated
with ("This is an exception thrown from java").  However, the
Throwable::getMessage() method is not giving me anything on the php
side, but it is giving me what I want on the java side.  Conversely,
the Throwable::getCause() is giving me exactly what is expected.

Any thoughts or help would be greatly appreciated!


Cheers,


Zach

Thank you, I'll see if I can select the user that tomcat is running  
in. Running "java -jar JavaBridge.jar" as a normal user does not  
exhibit this problem.

Hi,

> [...]I would just like to remove the everyone execute permissions.

Java uses a fine grained access control mechanism built into the VM, which is similar to Security
Enhanced Linux or the mechanism built into Vista. However, even with SEL and Java access control
enabled, one shouldn't run Java from the super user account.

Depending on the VM version, Java creates JIT code in /tmp or in some subdir of home directory.
Therefore this directory needs execute permission.

Hi,

as most modern Mac operating systems are based on Mach + Unix emulation layer, no special build or
deploy instructions are needed.

Please note that, in order to use all features, Java 6 or Java 7 is required. The bridge still
runs under Java 1.4, but some features, such as JSR223, may not be available.

Jost Boekemeier

Hi:

System: Mac Pro
OS: 10.5.2

I copied test.php from /opt/local/share/java/tomcat5/webapps/ 
JavaBridge to ~/Sites/JavaBridge/test.php for this example:

http://localhost/~kent/JavaBridge/test.php

Works great.

http://localhost:8080/JavaBridge/test.php

Displays a blank page and the following error in catalina.err:

> May 3, 2008 10:27:20 PM org.apache.catalina.core.ApplicationContext  
> log
> INFO: /var/root: Permission denied


Permissions on /var/root (root's login directory) were: 750, I needed  
to allow everyone execute permissions to /var/root:

$ sudo chmod 751 /var/root

to have this error go away - the test.php and the PHP/Java Bridge  
examples page now display. What is tomcat and JavaBridge doing that  
needs access to /var/root ?

Here is how I installed the php/Java bridge:

I installed tomcat and php via port:

sudo port install php5 +fastcgi fcgi	# php-cgi needed for Java/PHP  
bridge
sudo port install tomcat5		# Appache TomCat needed for Java/PHP bridge

I downloaded php-java-bridge_5-1.2.2_j2ee.zip from sf.net, unziped it  
and placed the JavaBridge.war file into /opt/local/share/java/tomcat5/ 
webapps/. I copied test.php and java/Java.inc to the ~/Sites/ 
JavaBridge directory. Then updated the php_exec to point to port's php- 
cgi:

$ unzip php-java-bridge_5-1.2.2_j2ee.zip
$ cd php-java-bridge_5-1.2.2_j2ee
$ cp JavaBridge.war /opt/local/share/java/tomcat5/webapps/
$ cp /opt/local/share/java/tomcat5/webapps/JavaBridge/java/Java.inc ~/ 
Sites/JavaBridge/java/Java.inc
$ cp /opt/local/share/java/tomcat5/webapps/JavaBridge/test.php ~/Sites/ 
JavaBridge/test.php

I edited /opt/local/share/java/tomcat5/webapps/JavaBridge/WEB-INF/ 
web.xml and added support for my Macport installed php:

   <init-param>
     <param-name>php_exec</param-name>
     <param-value>/opt/local/bin/php-cgi</param-value>
   </init-param>

Everything seems to be running, I would just like to remove the  
everyone execute permissions.

I did look for a php/Java Bridge Macintosh 10.5 HOWTO and didn't see  
on using google or the sf.net mail list archive search. I still need  
to install this on my laptop development system. Is there a repository  
for system specific installs (I did look in http://php-java-bridge.sourceforge.net/pjb/installation.php 
  and no Macintosh examples there)?

If there isn't one now, I can create one. Where should I send it?

Hi,

I have used "is_null(java_values($javaValue))". 
Here are the two functions from my code. The first one
is the one that does not works as it should work.


function getRepositoryFactory(){
	global $CFG;

require_once($CFG->dirroot.'/depths/setup/depths_config.php');
	$javabridge=get_string('javabridge','depths'); 
  	require_once($javabridge); 
	$myLib=get_string('moodle_jar_file','depths');
	java_require($CFG->wwwroot.'/'.$myLib);
	$session=java_session();
	$rep=$session->get($rep);
		if(is_null(java_values($rep))){
		try{
			$rep=new Java("depths.moodle.RepositoryFactory");
			$session->put("rep",$rep);
			if(is_null(java_values($rep))){
				throw new Exception("Could not create
repository!");
			}
			}catch(Exception $e){);	}
		}
		return $rep;
}
function getProjectFactory($sesame){
	global $CFG;

require_once($CFG->dirroot.'/depths/setup/depths_config.php');

	$javabridge=get_string('javabridge','depths');
	require_once($javabridge); 
	$myLib=get_string('moodle_jar_file','depths');
	java_require($CFG->wwwroot.'/'.$myLib);
	$session=java_session();
	 $projectFact=$session->get("projectFact");
	if(is_null(java_values($projectFact))){
		try{
					$projectFact=new
Java("depths.moodle.ProjectsFactory",$sesame); 
					$session->put("projectFact",$projectFact); 
				  }	catch (JavaException $ex){
						$exStr=java_cast($ex, "string");
						echo "Exception occured; mixed trace: $exStr\n";
						$trace=new

						$ex->printStackTrace(new

	}

I think it depends on how you do the check.

  is_null(java_values($javaValue)) or
java_is_null($javaValue) or if
 (!(string)$javaValue)

will work.

  if (!$javaValue) 

will not.

Hi,

the error message "Incorrectly typed data found for annotation element public abstract"
sounds like a bug in your application code. Or the application missing some required environment
variables.

I suspect one of the usual problems:

* class version problems (java doesn't have a proper module system); try to remove all unnecessary
jar files from the path, and/or start Java with the -verbose option to see which class versions
are loaded.

* the generated dynamic proxy needs some other JVM implementation. Please try to run your Java
application from the console. If that works, simply attach a JavaBridgeRunner to it and call your
application via that port.

The J2EE folder from the source download contains several examples which show how to use the
bridge to connect to a SOAP and EJB service.

Jost Boekemeier

The third party code uses java vers. 1.5.0_15.

Hi,
   
  I've solved this issue. It was not related with serialization problem, but with trying to access not existing java collection element from php.
   
  During my work on resolving this I have found other strange think that I can't explain. One PHP page is called multiple times, as it uses multipage presentation with limited number of items on each page. This page creates 3 java session variables on exactly the same way, first it checks if variable already exists and if not it creates it and put in session. 
  When calling this page multiple times throgh "next page", two variables work fine (i.e. they are created only the first time) and the third one is created each time. 
  The application works without problem, but I want to correct this as it is a time consuming process.
   
  Is there any ideas on this?

Hi,
   
  I have the error java.io.NotSerializableException that causes my application to fails. My PHP application, PHP/Java bridge and jar file used are all on the same Tomcat server, and I have removed tag <distributable> from WEB-INF/web.xml.
   
  Can you suggest me what causes the problem here.
  Tomcat error log is bellow.
   
  Regards,
  Zoran
