首先在PL/Sql中分别执行：
create or replace and compile java source named TestJava1 as
public class TestJava1
{
public static void test()
{
System.out.println("Hello");
}
}
create or replace procedure testJava1 as language java name 'TestJava1.test()';

在SQLPlus中
C:\Windows\System32>sqlplus nc5520110105/nc5520110105@192.168.10.87
SQL*Plus: Release 11.2.0.1.0 Production on Fri Apr 1 14:06:02 2011
Copyright (c) 1982, 2010, Oracle. All rights reserved.
Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
SQL> set serveroutput on;
SQL> show serveroutput;
serveroutput ON SIZE UNLIMITED FORMAT WORD_WRAPPED
SQL> call dbms_java.set_output(2000);
Call completed.
SQL>
SQL> show serveroutput;
serveroutput ON SIZE UNLIMITED FORMAT WORD_WRAPPED
SQL> exec testJava1();
Hello
PL/SQL procedure successfully completed.

---------------------------------------------------------------------------------------------------------
再看一个例子：
在PL/Sql中执行：
--用Java编写Oracle存储过程。
create or replace and compile java source named test as
public class MyTest
{
public static void myProc(int a,int b,int[] ret){
ret[0]=a+b;
}
public static int myFunc(int a,int b){
return a+b;
}
}
--创建存储过程
create or replace procedure myProc(a in number, b in number, ret out number) as
language java name 'MyTest.myProc(int,int,int[])';
--创建函数
create or replace function myFunc(a in number, b in number) return number is
language java name 'MyTest.myFunc(int,int) return int';
然后在SqlPlus中测试存储过程——
SQL> set serveroutput on
SQL> DECLARE a INTEGER;
2 BEGIN
3 myProc(1, 2, a);
4 DBMS_OUTPUT.PUT_LINE(a);
5 END;
6 /
3
PL/SQL procedure successfully completed.
SQL> select myFunc(1,2) from dual;
MYFUNC(1,2)
