Java class in Oracle 8i.

Question

Hi All,
I have tried to create a java class in Oracle8i but it throws some errors like:
NAMED "MyTime"
ERROR at line 3:
ORA-29516: Aurora assertion failure: Assertion failure at eox.c:187
Uncaught exception Root of all Java exceptions:
The program is :
CREATE OR REPLACE
JAVA SOURCE
NAMED "MyTime"
AS
import java.lang.String;
import java.sql.Timestamp;
public class MyTime
public static String getTime()
return (new Timestamp(System.currentTimeMillis())).toString();
Please give a solution ASAP.
If anybody knows give me more information about how the classes are created in the database and how itz get compiled.
Thanks in advance.

Anurag,
Here's an example of one I wrote which is VERY simple. Sometimes it helps to crawl before tou walk. You can execute the following using SQL*Plus:
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "RuntimeExample" AS public class RuntimeExample {
public static String runNotepad() {
String returnValue = null;
Runtime r = Runtime.getRuntime();
long totalMemory = r.totalMemory();
try {
     Process p = r.exec("notepad.exe");
     returnValue = p.toString();
     } catch (Exception e) {
          System.out.println("Exception calling Runtime.exec()->" + e);
     /* You can get creative here and
     1) Use p.waitFor() to block while the process is running,
     2) Send the command to be executed as a parameter to the method, etc. */
     return returnValue;
Notice that I return the string equivalent of Process p. This tells you if a process was really started.
Hope this helps,
