[Php-java-bridge-users] PHP-Java Bridge Unsatisfied Link Error with own jar/classes

[<php...@li...>]

Hi,

Quick bit of support with running what I'm pretty sure is a correctly installed Tomcat 7.0.5 and PHP-JavaBridge installation environment. I am running on Mac OS X 10.6.6, using MAMP (PHP 5.3, Apache  2.0 on port 80 etc) and have Tomcat 7.0.5 (port 8080) installed. I can run any php code successfully, the Tomcat examples all run successfully and if I deploy JavaBridge.war, copy the JavaBridge directory over to my local htdocs root (as per installation instructions if you get the FASTCGI error) then I can also run all the JavaBridge examples successfully. So a vanilla install is looking good. I can run the following code php script from my htdocs local root and it works fine as an example:

<?php
require_once("http://localhost:8080/JavaBridge/java/Java.inc");
$i1 = new Java("java.math.BigInteger",  "1");
$i2 = new Java("java.math.BigInteger",  "2");
$i3 = $i1->add($i2);
echo $i3->toString() . "\n";
?>

So I now move onto wanting to instantiate classes from my own jar file called SolverSDK.jar. As per the installation instructions, I grabbed a copy of JavaBridge.war, exploded it, add in my jar file to the WEB-INF/lib directory, re-create the war file using  "jar -cvf JavaBridge.war *", un-deploy the existing JavaBridge app in Tomcat, copy in my new one and re-start Tomcat. The updated war file deploys fine and I can run the above sample script again all ok. However, when I try to run the below simple script:

<?php
require_once("http://localhost:8080/JavaBridge/java/Java.inc");
$problem = new Java("SolverPlatform.Problem");
?>

I get the following error:

Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: CreateInstance failed: new SolverPlatform.Problem. Cause: java.lang.UnsatisfiedLinkError: no SolverSDK in java.library.path VM: 1.6.0_22@http://www.apple.com/" at: #-36 java.lang.ClassLoader.loadLibrary(ClassLoader.java:1754) #-35 java.lang.Runtime.loadLibrary0(Runtime.java:823) #-34 java.lang.System.loadLibrary(System.java:1045) #-33 SolverPlatform.Problem.(Unknown Source) #-32 java.lang.Class.forName0(Native Method) #-31 java.lang.Class.forName(Class.java:247) #-30 php.java.bridge.Util.classForName(Util.java:1518) #-29 php.java.bridge.JavaBridge.CreateObject(JavaBridge.java:445) #-28 php.java.bridge.Request.handleRequest(Request.java:458) #-27 php.java.bridge.Request.handleOneRequest(Request.java:510) #-26 php.java.servlet.PhpJavaServlet.handleLocalConnection(PhpJavaServlet.java:202) #-25 php.java.servlet.PhpJavaServlet.handlePut(PhpJavaServlet.java:250) #-24 php.java.servlet.PhpJavaServlet.doPut(PhpJavaServlet.java:261) #-23 javax.servlet.http.HttpServl in http://localhost:8080/JavaBridge/java/Java.inc on line 195

A browser refresh then results in the good old ClassNotFound error due since I would assume to the need for only one class-loader.

The SolverSDK.jar file has the correct layout when exploded, i.e. SolverPlatform directory and then all the classes etc. It relies on a file called "libSolverSDK.dylib" which is also included within the updated war file in the same directory. I have tried everything I can think of, including forcing the classpath in the Tomcat config file, setenv.sh etc. I have even ensured that DYLD_LIBRARY_PATH is set in a desperate attempt though I know this should have no effect within Tomcat. I am pretty familiar with Java and PHP but for the life of me, I can see no reason why I am getting this simple error. I have, as per the video demo on the site, even tried using the classes rather than the jar itself, in a newly created directory WEB-INF/classes but again after redeploying, I get the same error.

I have trawled through the mailing list archive and the web but not got anywhere. Any help would be greatly appreciated.

Regards,

Marc
