、存储过程调用java source
create or replace procedure socket(
ip varchar2,
context raw
)
as
language java name
‘JYM.say(java.lang.String,byte[])‘
;
3
、触发器调用存储过程
create or replace trigger todata_after
after insert on todata
for each row
begin
socket(‘192.168.9.12‘,:
new.context);
end todata_after;
代码写好后可以先用存储过程测试：
Sql代码
call socket(‘192.168.9.12‘,‘023132‘
);
为了能在控制台中看见错误信息，要先运行下面3句话
set serveroutput on;
set serveroutput on size 5000
;
call dbms_java.set_output(5000
);
假如你运行存储过程时爆出了 请给用户复制权限的提示则按照提示在sysdba 下赋权限，如：
Sql代码
exec dbms_java.grant_permission(‘zhym‘,‘SYS:java.net.SocketPermission‘,‘192.168.9.12:18002‘,‘connect,resolve‘
)
exec dbms_java.grant_permission(‘ZHYM‘,‘SYS:java.net.SocketPermission‘,‘127.0.0.1:1521‘,‘connect,resolve‘
)
execdbms_java.grant_permission(‘zhym‘,‘SYS:java.net.SocketPermission‘,‘192.168.9.12:18002‘,‘connect,resolve‘
)
execdbms_java.grant_permission(‘ZHYM‘,‘SYS:java.net.SocketPermission‘,‘127.0.0.1:1521‘,‘connect,resolve‘
)
exec 后面的语句会在你的报错提示中打印出来，只要前面加exec就可以了。
