Error loading a java class to oracle db

Question

hi,
my oracle server: 8i Enterprise Edition Release 8.1.7.0.0
i want to load a simple java class into my oracle server.
java source:
public class Ping
     java.lang.String server;
     public static void main(java.lang.String[] args)
          System.out.println(new Ping().runCmd(args[0]));
     public static java.lang.String runCmd(String cmd)
boolean result=false;
int timeout=5000;
try {            
java.net.InetAddress byName=java.net.InetAddress.getByName(cmd);
               result=byName.isReachable(timeout);
catch(java.io.IOException e)
e.printStackTrace();
     java.lang.String retVal=java.lang.Boolean.toString(result);
          return retVal;
after compiling the java file. i'm using loadjava at dos prompt.
loadjava -user uname/pwd@db -resolve Ping.class
this command results in
ORA-29545: badly formed class:
loadjava: 1 errors
alternatively i had used a command
loadjava -user uname/pwd@db -noverify -resolve Ping.class
this command results in
Error while turning off verifier
ORA-29532: Java call terminated by uncaught Java exception: java.security.Ac
cessControlException: the Permission (oracle.aurora.security.JServerPermission V
erifier ) has not been granted by dbms_java.grant_permission to SchemaProtection
Domain(SMSPGS|PolicyTableProxy(SMSPGS))
ORA-29545: badly formed class:
loadjava: 2 errors
but user is having sufficient rights (javasyspriv)
what is wrong above, please help me.

hi,
thanks for your response
Ping.class just checks whether the specified node is reachable or not.
result=byName.isReachable(timeout);
the jdk loaded in oracle DB is older one and the method above java.net.InetAddress.isReachable(java.lang.int) is available since
jdk 1.5
source:
public class Ping
java.lang.String server;
public static void main(java.lang.String[] args)
System.out.println(new Ping().runCmd(args[0]));
public static java.lang.String runCmd(String cmd)
boolean result=false;
int timeout=5000;
try {
java.net.InetAddress byName=java.net.InetAddress.getByName(cmd);
result=byName.isReachable(timeout);
catch(java.io.IOException e)
e.printStackTrace();
java.lang.String retVal=java.lang.Boolean.toString(result);
return retVal;
}how to load the new jdk set into existing oracle db server and replace the existing jdk.
what can be done to achieve this ?
