SocketPermission & Uncaught Java Exception Problems

Question

Hi,
I'm trying to run a applet that uses BC4J.
But I'm getting a SocketPermission - resolve-connect - problem.
When I try to grant "connect-resolve" permissions using the DBMS_JAVA procedure,
EXEC DBMS_JAVA.GRANT_PERMISSION('CONFIG','SYS:java.net.SocketPermision', '3.8.180.87', 'connect,resolve');
I'm getting the following exception:
ERROR at line 1:
ORA-29532: Java call terminated by uncaught Java exception:
java.lang.SecurityException: policy table update SYS:java.net.SocketPermision,
3.8.180.87
ORA-06512: at "SYS.DBMS_JAVA", line 0
ORA-06512: at line 1
BTW,
Both the Web Server and the Oracle DB Server are in the same computer.
I tried with both: SYSTEM and SYS users.
"CONFIG" is a DB existent schema -user-
"3.8.180.87" is the web & db server -I tried "*", too, but I got the same error-.
Could some body help me, please?
I think I'm doing the right steps -procedure.
Thanks in advance,
Agustin

I'm in the process of publishing the following note (134280.1), titled "How to Resolve ORA-29532 Java 2 Permission Problems in RDBMS 8.1.6 and 8.1.7".
It will be accessible from Oracle Support's "Metalink" site.
"How to Resolve ORA-29532 Java 2 Permission Problems in RDBMS 8.1.6 and 8.1.7".
Problem Description
Periodically an application running in the Enterprise Java Engine
(EJE) formerly known as the "Oracle 8i JVM", "the JSERVER component", or
the "Aurora JVM" will fail with a "java 2" permissions error having the
following format :
Note : Message shown below have been reformatted for easier readability.
java.sql.SQLException: ORA-29532: Java call terminated by uncaught Java exception:
usually followed by a detailed error message similar to one of the following
messages :
Example # 1
java.security.AccessControlException: the Permission
(java.net.SocketPermission hostname resolve)
has not been granted by dbms_java.grant_permission to
SchemaProtectionDomain(SCOTT|PolicyTableProxy(SCOTT))
Example # 2
java.security.AccessControlException: the Permission
(java.util.PropertyPermission * read,write)
has not been granted by dbms_java.grant_permission to
SchemaProtectionDomain(SCOTT|PolicyTableProxy(SCOTT))
Example # 3
java.security.AccessControlException: the Permission
(java.io.FilePermission \matt1.gif read)
has not been granted by dbms_java.grant_permission to
SchemaProtectionDomain(SCOTT|PolicyTableProxy(SCOTT))
Explanation
The java 2 permission stated in line # 2 of each of the above "Examples"
has not been granted to the user specified in line 4 of the above "Examples".
Solution Description
The methodology to solve this issue is identical for all java 2 permissions
cases.
1) Format a call "dbms_java.grant_permission" procedure as described below.
2) Logon as SYS or SYSTEM
3) Issue the TWO commands shown below
4) Logoff as SYS or SYSTEM
5) Retry your application
For Example # 1
1) Logon as SYS or SYSTEM
2) Issue the following commands :
a) call dbms_java.grant_permission('SCOTT',
'java.net.SocketPermission',
'hostname',
'resolve');
b) commit;
Note: Commit is mandatory !!
3) Logoff as SYS or SYSTEM
4) Retry your application
For Example # 2
1) Logon as SYS or SYSTEM
2) Issue the following commands :
a) call dbms_java.grant_permission('SCOTT',
'java.util.PropertyPermission',
'read,write');
b) commit;
Note: Commit is mandatory !!
3) Logoff as SYS or SYSTEM
4) Retry your application
For Example # 3
1) Logon as SYS or SYSTEM
2) Issue the following commands :
a) call dbms_java.grant_permission('SCOTT',
'java.io.FilePermission',
'\matt1.gif',
'read');
b) commit;
Note: Commit is mandatory !!
3) Logoff as SYS or SYSTEM
4) Retry your application
