Sharing XML packages among users

Question

Hello all,
I have a question about the installation of the Oracle XML packages and sharing them among users.
Our DBA thought it might be best to create a special user (user1) and install all of the XML packages, utilities under that user schema. We went this route and were trying to use that users's xml objects with another user (user2).
When trying to generate XML output from SQL using the xmlgen package as user2 we get the following error.
SQL> set serveroutput on size 1000000
SQL> DECLARE
2 v_query VARCHAR2(200) := 'SELECT ''monkey'' AS Animal FROM dual';
3 BEGIN
4 DBMS_OUTPUT.PUT_LINE(DBMS_LOB.SUBSTR(xmlgen.getXML(v_query), 250, 1));
5 END;
6 /
DECLARE
ERROR at line 1:
ORA-29532: Java call terminated by uncaught Java exception: java.util.MissingResourceException:
can't find resource for oracle.xml.sql.mesg.XSUMessages_en_US
ORA-06512: at "SXXML.XMLGEN", line 465
ORA-06512: at "SXXML.XMLGEN", line 456
ORA-06512: at line 4
However running that same anonymous PL/SQL block as user1 we get success:
SQL> set serveroutput on size 1000000
SQL> DECLARE
2 v_query VARCHAR2(200) := 'SELECT ''monkey'' AS Animal FROM dual';
3 BEGIN
4 DBMS_OUTPUT.PUT_LINE(DBMS_LOB.SUBSTR(sxxml.xmlgen.getXML(v_query), 250, 1));
5 END;
6 /
<?xml version = '1.0'?>
<ROWSET>
<ROW num="1">
<ANIMAL>monkey</ANIMAL>
</ROW>
</ROWSET>
So I have several questions:
1> What is the best way to install these XML packages so that all users can use these utilities?
2> What access privileges need to be granted to user2 so that user1 AML utilities are available?
Thanks in advance.

Answer 1

Thanks for the quick reply Steve: I have an observation and a couple of questions.
First my observation. I looked for the java resource that "turned up missing" as far as my user2 user is concerned and I couldn't find it in sxxml's schema. ( I was logged in as sxxml). I attempted to create a wrapper package belonging to sxxml sxhema as I understood. However even after granting execute privilege to my second user I got the same message.
Finally I removed the authid as current_user tag from the package declaration and I was able to get it to work.
I am not comfortable with this solution and would like to get this set up the right way. You said my second option was to grant execute privilege on the missing Java resource to my second user.
How do I locate this "missing" Java resource?
How do I grant execute privilege to a Java resource?
What are the ramifications of solving the problem the way I did?
Thanks again for your help.

create or replace package xmlgen AUTHID CURRENT_USER...This means that it runs under the security domain of whatever user executes it, not under the security domain of the package owner/definer.
Either GRATN EXECUTE on this Java resource to your new user, or alternatively, have your SXXML schema create a wrapper package for XMLGEN that is created using the default of definer's rights. Then, anyone that you GRANT EXECUTE to your wrapper procedure can use it.<HR></BLOCKQUOTE>
