A twist on a java.security.AccessControlException
A twist or quirk, I’m not sure. I was working on a internal Java library to delete external files when I encountered an ORA-29532. The error said that I needed to grant read file permissions but it really required read, write, and delete permissions. Worse yet, they’d already been granted.
Then, I remembered that this is the instance that I built before assigning a hostname in the C:\WINDOWS\system32\drivers\etc\hosts file. I’d blogged about it earlier, describing how to drop and recreate the Enterprise Manager. I had a hunch, and it worked.
I ran the following:
BEGIN DBMS_JAVA.GRANT_PERMISSION('SYSTEM' ,'SYS:java.net.SocketPermission' ,'<strong>hostname</strong><em></em>:1521' ,'connect,resolve'); END; / |
Then, I reconnected as the test user and everything worked fine. The full error received:
BEGIN delete_file(get_canonical_local_bfilename(:locator)); * ERROR AT line 1: ORA-29532: JAVA call terminated BY uncaught JAVA EXCEPTION: JAVA.security.AccessControlException: the Permission (JAVA.io.FilePermission C:\JavaDev\BFileFramework\HarryPotter1.png read) has NOT been granted TO PLSQL. The PL/SQL TO grant this IS dbms_java.grant_permission( 'PLSQL', 'SYS:java.io.FilePermission', 'C:\JavaDev\BFileFramework\HarryPotter1.png','read' ) ORA-06512: AT "PLSQL.DELETE_FILE", line 1 ORA-06512: AT line 1 |
You can get the full Java stack trace by two steps:
1. Call the DBMS_JAVA.SET_OUTPUT(2000000);
2. Set SERVEROUTPUT ON
