Missing LogManager Class in JVM.

We are having trouble resolving to the LogManager Class in the
java/util/logging/ package when attempting to access it through an RPG
interface. 

When we run a similar program in QSHELL it works. 

Our Java programmer knows next to nothing about the iSeries and I have
an adequate, but limited knowledge of Java. In the RPG I have the
following test code:

 

 

d newTest         PR              O   EXTPROC(*JAVA                     

d                                            :'au.com.eigansvar.-       

d                                     web.webservices.userdb.client.-   

d                                     TestLogManager'                   

d                                            : *CONSTRUCTOR)            

d                                     CLASS(*JAVA                       

d                                          :'au.com.eigansvar.-         

d                                     web.webservices.userdb.client.-   

d                                     TestLogManager')

 *   

d testIt          PR              O   EXTPROC(*JAVA


d                                            :'au.com.eigansvar.-


d                                     web.webservices.userdb.client.-


d                                     TestLogManager'


d                                            : 'testIt')


d                                     CLASS( *JAVA : 'java.lang.String')

 

d testObj         S               O   CLASS(*JAVA


                                          :'au.com.eigansvar.-


                                     web.webservices.userdb.client.-


                                     TestLogManager')   

 

 

d getName         S                   like(jstring) 

 

c                   eval      testObj= newTest()         

c                   eval      getname= testIt(testObj)      

 

The program fails on the last line with:


 

 

Message . . . . :   Java exception received when calling Java method.


Cause . . . . . :   RPG procedure JAVTST07 in program ANVDEV/JAVTST07
received

  Java exception "java.lang.NoClassDefFoundError:


  java/util/logging/LogManager" when calling method "testIt" with
signature   

  "()Ljava.lang.String;" in class


  "au.com.eigansvar.web.webservices.userdb.client.TestLogManager".


Recovery  . . . :   Contact the person responsible for program
maintenance to 

  determine the cause of the problem.


Technical description . . . . . . . . :   If the exception indicates
that the 

  Java class was not found, ensure the class for the method is in the
class   

  path. If the exception indicates that the Java method was not found,
check  

  the method name and signature. If the signature is not correct, change
the  

 

 

The java class is as follows:

 

package au.com.eigansvar.web.webservices.userdb.client;

import java.util.logging.LogManager;

public class TestLogManager {

    public static void main(String[] args) {

        System.out.println("Testing if LogManager class exists in the
system");

        LogManager logManager = LogManager.getLogManager();

        if (logManager == null) {

            System.out.println("It's null");

        } else {

            System.out.println("It's there");

        }

    }

    

    public String testIt() {

        LogManager logManager = LogManager.getLogManager();

        if (logManager == null) {

            return "It's null";

        } else {

            return "It's there";

        }

    }

}

 

 

In the QSHELL we ran the following:

 

cd /java/leo


$


java -cp . au.com.eigansvar.web.webservices.userdb.client.TestLogManager


Testing if LogManager class exists in the system


It's there


$

 

The Java programmer thought that the JVM may be using an earlier JDK
however as far as I can tell, both the JVM and QSHELL are running the
same JDK. I found this with the following iSeries command:

 

JAVA *VERSION

 

Version JVM V5R3M0 JDK 1.4.2.  

 

And in QSHELL:

 

java -version           

java version "1.4.2"    

$        

 

Any obvious errors I've made, or hints to help me solve this will of
course be greatly appreciated.
