Loading jar files and calling java stored procedure

I am trying to load jai_core.jar, jai_codec.jar, mlibwrapper.jar and another class I created into my project schema. I am having problems with resolving all of the class using the "loadjava -resolve" command as well as using the "alter java class" command. The single class I authored is not in a valid state as well as the PL/SQL wrapper for the function I am calling.
My questions are:
1) Does the single class need to be in a valid state before the PL/SQL wrapper will compile and be in a valid state itself?
2) Are there any special tricks to this becuase the code I am using below doesn't seem to be working correctly?
3. Should I worry about "resolving/validating" all of the class from the jar file? I have read conflicting views on this topic.

Any help would be greatly appreciated.

We are using Oracle 9.2.0.8 and I have written the single class in 1.3.1.
The first loadjava commands I tried were:
loadjava -user username/password -resolve -resolver '((* RTRPROD)(* PUBLIC))' jai_core.jar jai_codec.jar mlibwrapper_jai.jar
loadjava loadjava -user username/password -resolve -resolver '((* RTRPROD)(* PUBLIC) (* -))' ImageUtility.class
Then I tried:
loadjava -user username/password -resolve -resolver '((* RTRPROD)(* PUBLIC) (* -))' jai_core.jar jai_codec.jar mlibwrapper_jai.jar
errors : class javax/media/jai/operator/EncodeDescriptor
ORA-29534: referenced object RTRPROD.com/sun/media/jai/codec/ImageCodec could not be resolved

This error messages goes on and on for 44 files.
I have found out that JAI is part of the Oracle 9 Release 2 but is part of the InterMedia package that is not installed. I would imagine that the JAI libraries mentioned above would be included in InterMedai. However, there are several dependencies on packages distributed in the Sun JDK but not the Oracle Runtime.

How to open external files in a Java stored procedure?

Hi y'all,
I'm trying to open an external text file from a Java stored procedure. The java sp has been successfully loaded, resolved, published, etc. in Oracle. I'm using the following statement to try to open the file (enclosed in a try/catch block):
BufferedReader fileObj = new BufferedReader(new FileReader("fileName.txt"));
I'm getting a file not found error. Where is Oracle looking (i.e., what directory)?
Your help is greatly appreciated,
Gary

you must use a "database directory", e.g:

21700 while calling java stored procedure in 9i

I create a java stored procedure that takes a varray of a rowtype. When I call that procedure, I get an ora-21700. If I remove the varray from the parameter list, I can call the procedure okay. My goal is to create a generic java procedure that can take a rowtype from any table and create XML. Once I get the oracle.sql.ARRAY into my code, I am okay. I just can't seem to pass it in. I have pasted my code below:
Java:
import oracle.sql.*;
public class test {
public static String sayHello() {
return("Hello, World!");
public static void genXML(oracle.sql.ARRAY a, oracle.sql.CLOB c) throws Exce
ption {
c.putString(1,"<test>This is a test!</test>");
PL/SQL:
create or replace package mike is
type dummy_record is varray (1) of dummy%rowtype;
PROCEDURE GENERATE_XML(i dummy_record, c CLOB);
FUNCTION SAYHELLO RETURN varchar2;
end mike;
show errors
create or replace package body mike is
PROCEDURE GENERATE_XML(i dummy_record,c CLOB)

FUNCTION SAYHELLO RETURN varchar2

end mike;
show errors

select xml into c from t_clob;
for rec in (select * from dummy)
LOOP
m(1) :=rec;
mike.generate_xml(m,c);
end loop;
end;
And finally, the output:
declare
ERROR at line 1:
ORA-21700: object does not exist or is marked for delete
ORA-06512: at "MMANGINO.MIKE", line 0

Sorry this post is so long, but I wanted it to be complete!
Mike

The first solution is to not do that in java in the first place.
DDL should be in script files which are applied to oracle outside of java.
Other than I believe there are some existing stored procedures in Oracle that take DDL strings and process them. Your user has to have permission of course. You can track them down via the documentation.

ORA-29532 when trying to write to a file using a Java stored procedure

I have a Java stored procedure which gives me the following error when I run it:-
SQL> exec zipfile('c:\temp\test.txt');
BEGIN zipfile('c:\temp\test.txt'); END;
ERROR at line 1:
ORA-29532: Java call terminated by uncaught Java exception:
java.security.AccessControlException: the Permission (java.io.FilePermission
c:\temp\test.txt.zip write) has not been granted to SCOTT. The PL/SQL to grant
this is dbms_java.grant_permission( 'SCOTT', 'SYS:java.io.FilePermission',
'c:\temp\test.txt.zip', 'write' )
ORA-06512: at "SCOTT.ZIPFILE", line 1
ORA-06512: at line 1
I have tried running the dbms_java command as recommended as sys and have performed the necessary commit afterwards, also I have ran dbms_java.grant_permission( 'SCOTT', 'java.io.FilePermission',
'*', 'write' )
But I still get the ORA-29532.
Does anyone have any ideas as to how I can get around this ?

Are you getting ORA-29532 for the same file and the same permission ?

Hi again, Daniel,
I'm only guessing here, but unless you've made lots of mistakes when
you copied your code to your post to the forum, your method signatures
don't match. The definition of "genFile" in your java class is quite
different to what you wrote in your PL/SQL wrapper.
Also, you have defined "genFile" to be a private method -- I think it
needs to be public.
Also, I think the "main" method doesn't need to be in the "GenFiles"
class -- perhaps you should remove it.
Also, I think in your PL/SQL wrapper you need to use fully qualified
names, so use "java.lang.String" and not just "String".
Lastly, I think you should use the "-force" and "-resolve" flags
with the "loadjava" command.
Good Luck,
Avi.

How to call java stored procedure using RMI?

Is it possible to make a call to java stored procedure using RMI. ?
How can I run the RMI registry on the Oracle Server ?

<BLOCKQUOTE>quote:<HR>Originally posted by Thomas Grounds ([email protected]):

In principle it is possible. See the Java-Doc.s of Oracle 8.1.6.
I have successful granted the java.net.SocketPermissions in my USER_JAVA_POLICY view (see Doc.) Now I was able to use the RMI-Sockets, but following
failure try to connect to RMI-Object via RMIregistry an Oracle Error occurs
ORA-03113: end-of-file on communication channel
and after that my Oracle Connection is closed.

I think you do not need the RMI registry on Oracle Server. It should be possible to start the RMI registry wherever you want in your network and access it via the right registry string.

CLASSPATH configuration for jsp (java stored procedures)

Hi.
I have a very simple question for you people.
I don't know where to set up the CLASSPATH configuration on a HP-UX so that Aurora can see this include jar file and my java stored procedure can run correctly.
Thanks a lot.
Flavio Matiello

The way global variables could be created using java classes is by using static variables.The class variable values are stored in the JVM's memory
In Oracle8i Each session gets its own JVM & hence you cannot have a Java class variable which could
span across sessions.
Hope this helps

Accessing files from Java Stored Procedures

I am trying to access a file from a Java Stored Procedure but get the exception: "no such file or directory". The path and filename as seen by the database JVM is "\\wgcaub01\a1500is\fabi\mmv\mmvtestdata.txt".
I have granted permissions to open the file using:
call dbms_java.grant_permission('MMV', 'java.io.FilePermission', '\\\\wgcaub01\\a1500is\\fabi\\mmv\\mmvtestdata.txt', 'read');
a) When I run the program as a Java class using a main method it works so the problem has to do with the Oracle JVM not finding the file.
b) The MMV user has permissions on the file after granting them using the above dbms_java.grant_permission command.
Can you tell me what am I missing? Is this a database configuration issue? Is there a problem with using a UNC path?
(I am using FileReader and BufferedReader.)

Vincent,
Not sure if this is the cause of your problem, but I had some Java code which read from/wrote to a file, and I needed to run the following (you can obviously change <<ALL FILES>> to something more restrictive):
declare
security_key number;
begin
dbms_java.grant_permission('DAN', 'java.io.FilePermission', '<<ALL FILES>>', 'read,write,execute,delete', security_key);
dbms_java.grant_permission('DAN', 'java.lang.RuntimePermission', 'writeFileDescriptor', NULL, security_key);
dbms_java.grant_permission('DAN', 'java.lang.RuntimePermission', 'readFileDescriptor', NULL, security_key);
end;
Note that the security_key won't be set if the grant didn't work.
Hope this helps,
-Dan

Transactional file output from a Java Stored Procedure invoked by trigger.

I need to write information to a file from a Java Stored
Procedure which is called from an insert trigger. This works OK
except for the condition when a rollback is performed - the file
is updated anyway.
I need the Java Stored Procedure file output to be part of the
transaction - performed on commit and skipped on rollback. Is
there any way the Java Stored Procedure can be aware of the
state of the transaction?

i am Still facing the following problem:
if i pass a parameter like :
rm -f /test/menu.ksh
then the required output is that the menu.ksh file gets deleted.
but when i pass this command:
./test/menu.ksh
It is supposed to execute the specified script but it does not.
I have tried multiple things like giving chmod 777 rights to the following file and changing the command to /test/menu.ksh but nothing happens
Can you kindly tell me what can the problem be. Is there any execution rights issue: i am executing these scripts from pl sql developer.

How to call EJB deployed on OC4J from java stored procedure?

Hello,
I'd like to call EJB from java stored procedure. My example works fine from command line, but the problem seems to be with deployment of this code into database. Especialy I'm wondering how to reference jars like oc4jclient.jar, ejb.jar, ... from java stored procedure.
Is there some example how to do that ?
Can You help me please ?
Many thanks,

Size limitation that can be passed to Java stored procedure

Hello!
I enjoy using Oracle8i these days. But I have some questions
about Java stored procedure. I want to pass the XML data to Java
stored procedure as IN parameter. But I got some errors when the
data size is long. Is there any limitation in the data size that
can be passed to Java stored procedure?
Would you please help me ?
This message is long, but would you please read my message?

2. About the data size boundary
I don|ft know the boundary that I got errors exactly, but I
found that the boundary will be changed if I use |gprepareCall("
CALL insertData(?)");|h or |gprepareCall ("begin insertData
(?); end ;")|h.
When I use |gprepareCall(" CALL insertData(?)".
The data size 3931 byte --- No Error
The data size 4045 byte --- Error
Whne I use prepareCall ("begin insertData(?); end ;")
The data size 32612 byte --No Error
The data size 32692 byte --- Error
3. The source code of the Java stored procedure
public class javaSpBytesSample {

try{
Connection l_connection; //Database Connection Object
//parse XML Data

Iam passing an array of objects from Java to the C
file. The total size of data that Iam sending is
around 1GB. I have to load this data into the Shared
memory after getting it in my C file. Iam working on
HP-UX (64-bit). Everything works fine for around 400MB
of data. When I try to send around 500MB of data, the
disk utilization becomes 100%, so does my memory
utilization and I get a "Not enough space" when I try
to access shared memory. I have allocated nearly 2.5GB
in my SHMMAX variable. Also, I have around 45GB of
disk free. The JVM heap size is also at 2048MB. Where did you get the 400/500 number from? Is that the size of the file?
What do you do with the data? Are you doing nothing but copying it byte for byte into shared memory?
If yes then a simple test is to write a C application that does the same thing. If it has problems then it means you have an environment problem.
If no then you are probably increasing the size of the data by creating a structure to hold it. How much overhead does that add to the size of the data?
