Re: [Php-java-bridge-users] Problem running with Ubuntu

Hi

Jar file is compiled with the wrong Java version - meaning a newer version than the one that your Tomcat is running on.

Emne: [Php-java-bridge-users] Problem running with Ubuntu

Hi,

I'm using Tomcat private instance on Ubuntu.  I have set up the bridge and can run the index and test programs.  I then insert a simple java jar program in the WEB-INF/lib as I step through a simple program when I call in php

require_once("java/Java.inc");
             $session = java_session();
             if(java_is_null($instName = $session->get("bean"))) {
               $session->put("bean", $instName=new Java("DoSimple"));
             }else {
               $session->put("bean", $instName=new Java("testString", "Test of Bridge"));
             }
             $rawInstNameA = java_values($instName->testAnArray($yrqtr));

against the simple java program:
public class DoSimple {
     public DoSimple(){
     }
     public void testString(String s3){
         System.out.println(s3);

     }
}

The Bridge fails in the call to the constructor:

The error output is:

It can't load the class.   I can't see why.  Can anyone help?  If there
is any other information that will help, I will gladly send it.

Thanks
Don
