1.编写一个java程序.

public class OracleJavaProc

{

public static void main(String[] argv)

{

System.out.println("It's a Java Oracle procedure.");

}

}

2.使用javac生成class

javac OracleJavaProc

3.在数据库中引用

create or replace java class using bfile(java_dir,'test.class');

create or replace procedure test_j as language java name 'OracleJavaProc.main(java.lang.String[])';

注意:

需建立一个directory目录

create or replace directory java_dir as '/home/oracle/java' ;

4.输出结果:

SQL>call dbms_java.set_output(5000);

SQL>exec test_j ;

It a Java Oracle procedure.

PL/SQL procedure successfully completed.
