Java Stored Procedure using XSU on 9i Lite

I have create Java Stored Procedure using XML SQL Utility to return results in XML format. I have tested the stored procedure on the development machine (with SDK and Webtogo)without any problem. When I tested it on the client machine (with only the lite database for Window download from the webtogo server as part of the setup), there's an error [POL-8035] no such attribute or method when I call the procedure through MSQL. However, after calling the stored procedure the 3rd times, it will return the results in XML. Once I logout after that, I will have to call the same SP 3 times (always 3 times) before I get the results.
I'm running on Win2000, Oracle lite 5.0.1. with jdk 1.3.1 - same for the development machine.
I'm using the same xsu12.jar file.
What did I miss?

Nothing?
No one? No ideias?

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 ?

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.

Deploying SQLJ classes as Java Stored Procedures using JDeveloper 10g

Hello,
I have defined a SQLJ class, MwaSqljDao.sqlj, in JDeveloper. When I right click on the SQLJ class and "make" the class. It appears to succeed.
However when I attempt to build the project in which the SQLJ class is a member of, a class that uses the SQLJ class has the following compile error:
- MwaSqljDao not found.
After a little digging it appears JDeveloper is able to compile the .sqlj file to a .java file in the classes output directory. However it does not take it to the next step of compiling the .java file into a .class file.
Is SQLJ still a main stream Oracle technology? Or has it been cast to way side to make way for other technology?
If SQLJ is still a supported Oracle technology how do go about compiling the SQLJ class using JDeveloper?
My goal is to deploy SQLJ into JServer as a Java Stored Procedure class.
Thank you,
Rob

Excellent.
Especially that you resolved it and even more so that you posted the solution.
I do wonder whether you would have gotten help (faster) has you asked in a JDeveloper-related forum such as " Forum Home » Developer Tools » JDeveloper and ADF" at JDeveloper and ADF

How to debug java stored procedures using jdwp with Eclipse IDE?

I need to debug the java stored procedures loaded in Oracle 9.2.0.6. The java files are loaded into the database using dbms_java.loadjava('-force -debug -verbose -resolve lib/java_stored_procs.jar'); The jar contains .java files and the database resolves and compiles them into .class files. Works fine but I need to debug the code. I am tried of the println method since takes too much and too many iterations.
My IDE is Eclipse 3.1. I want to use the jdwp for debugging in my IDE. Any one who knows the exact steps?
Thanks a lot.

Strangely behaving Java Stored Procedure using Sockets

Hi,
I have a java class which connects to 10.x.x.x:2100 to interact with a server to download some files using a custom protocol.
After using it for once and immediately invoking it again causes it to just return without actually invoking the java class.After say,1 minute if the same call is made it is invoked properly.
The call to the pl/sql wrapper is made from a .net application in an asynchronous callback.
What could be the cause.Did anyone run into this anytime.?
Thanks

Without a code example to run, it would be ahrd to say what is happening. It looks like there is an issue with blocking v.s. unblocking i/o that gets resolved after a wait period. If you can get me an example, I iwll take a look.

Java Stored Procedure using OCI

The RoomsInformationProcedure example code has errors !!!
The RoomsInformationProcedure.java doesn't work because the second query is incorrect:
// Query to find out total number of available rooms for a given Room Type
// and Hotel ID
stmt = connection.prepareStatement("SELECT TOTAL_"+ roomType +
" FROM room_availability WHERE " +
" hot_id = TO_NUMBER(?) AND " +
" booking_date = ( SELECT MAX(booking_date) " +
" FROM room_availability " +
" WHERE hot_id = TO_NUMBER(?) )" );
stmt.setString(1,hotelId); // Bind Input Hotel ID Parameter
stmt.setString(2,hotelId); // Bind Input Hotel ID Parameter ! ERROR !
stmt.setString(2,roomType); // Bind Input Room Type !OK !
Also review the columns name in the table.

No, the code is correct and it works as expected.
Here is why :
a) The relational table room_availability has following columns :
Name Null? Type
HOT_ID NOT NULL NUMBER(10)
BOOKING_DATE NOT NULL DATE
BOOKED_SGLB NOT NULL NUMBER(4)
BOOKED_DBLE NOT NULL NUMBER(4)
BOOKED_QEEN NOT NULL NUMBER(4)
BOOKED_KING NOT NULL NUMBER(4)
BOOKED_SUIT NOT NULL NUMBER(4)
BOOKED_OTHR NOT NULL NUMBER(4)
TOTAL_SGLB NOT NULL NUMBER(4)
TOTAL_DBLE NOT NULL NUMBER(4)
TOTAL_QEEN NOT NULL NUMBER(4)
TOTAL_KING NOT NULL NUMBER(4)
TOTAL_SUIT NOT NULL NUMBER(4)
TOTAL_OTHR NOT NULL NUMBER(4)
b) When you want to get total number of rooms for room type 'SGLB', for hotel with hot_id '7080', the above query becomes
select TOTAL_SGLB FROM room_availability WHERE hot_id = 7080 AND
booking_date = ( SELECT MAX(booking_date) FROM room_availability
where hot_id = 7080)
which returns expected value.
Note that : the roomType is appended to the sql query and is not binded to the prepared statement.

SQLJ and Java Stored Procedures

Hi,
Am very sorry, if I am taxing you too much with Java Stored Procedures!!
However, I have struggling with it for more than 3 days or so.So please bear with me
I am facing a peculiar problem on the subject.
I have deployed a Java Stored Procedure using Connection name as "JDBC" through JDev.
My client calls the Stored procedure getDept as follows:
int deptNo = 0;
String deptName = null,
deptLoc = null;
#sql {
call sample.getDept( :out deptNo,
:out deptName,
:out deptLoc)
In my project properties , in SQLJ tab, when I select "JDBC" as my connectionName, and leave the ContextName blank(i.e. DefaultContext), I get the following error :
Error: [26] Not Found: SAMPLE.GETDEPT There is no stored procedure with this name
When I leave the ConnectionName as blank (which I suppose means donot do online checking!!), it compiles OK.
Howvever, it is not able to run my SQLJ file!!
Cannot figure out why this is happening.Please help!!
TIA
Sandeep

Looks like Java stored procedure don't support the return of result sets to the client. Given the complexity and non-generic 'cursor ref' approach that Oracle has always implemented, I guess it is not too surprising. I suggest throwing the select into a work table and pulling the rows from there. If you are in a COM capable environment, you can use 0040 to get back a Dynaset, but be aware, it is live!
Good luck.

About BC4j and java stored procedure

Is it possible create a java stored procedure using BC4j and deploy to Oracle9iR2 VM?
If it is possible, how about the performance compare to PL/SQL stored procedure?

In 9.0.3.3 it will be possible again. The ability to deploy a BC4J-based, local-mode Java Stored Procedure was broken in 9.0.3 before this upcoming maintenance release.
PL/SQL will almost surely be faster if you are talking about just doing basic DML type of operations, when compared to Java stored procedures.

Connecting to a non-oracle database (jdbc) from a java stored procedure

Does anyone know to configure the database to allow a connection to a non-oracle database from a Java Stored procedured, using JDBC?
Thank you in advance,
Chris

Hi Chris,
I haven't tried it, and these are just some of my thoughts, but I
think you would need to load the JDBC driver for the other database
into the Oracle database (using the "loadjava" tool, of-course).
Then your java stored procedure should be able to instantiate the
third party JDBC driver and obtain a connection to the other database.
Hope this helps.
Good Luck,
Avi.

Java stored procedures and triggers in lite

Hi
We are using java stored procedures and java triggers in our application for oracle lite database 5.1.
We would like to know whether these procedures and triggers are uploaded or associated with tables or not because triggers are not being fired for the tables.
The question is - how to find the uploaded procedures and triggers in system tables.
We dont find any tables like (all_objects, user_objects) for this in oracle lite system catalogs given in the documentation.
thanks in advance
yugandhar

I don't have much experience with Lite, but I'm running 9i Personal Edition. Any information about triggers can be found in the "ALL_TRIGGERS" view. You will want to filter out any rows where OWNER = 'SYS' unless you created your triggers as SYS. As for procedures and functions, you can see what you have created in the "ALL_OBJECTS" view where OBJECT_TYPE = 'PROCEDURE' or 'FUNCTION', once again filtering out rows where OWNER = 'SYS'. To see the code of any procedure or function, select substr(text,1,80) from ALL_SOURCE where NAME = 'function name' ORDER BY LINE.
Hope this helps!

How to get connection of the db lite from java stored procedure?

Hello! All.,
I have a written java stored procedures to assign sequence keys, and update some tables. The procedure is working as per our need by using the following connection information.
try {
int rowFetched = 0;
Class.forName("oracle.lite.poljdbc.POLJDBCDriver");
// connect to the database
Connection conn = DriverManager.getConnection("jdbc:polite:polite",
"system", "manager");
My question is, It is possible in db lite to get a default connections like we use in the enterprise database
conn = new OracleDriver().defaultConnection();
Could anybody please shed some light on this.
Thanks in advance.
Kathir

Hello Upi! out of curiosity if you happen to know the answer for the following, I do appreciate it.
Hello! We are using BC/ADF JClient to select and for any DML operation against Oracle Lite database. We may have more than one user(s) log on to our application, so we requires to authenticate oracle lite user credential using JDBC dynamically.
I am utilizing the features of JCLoginDialog.java and manipulation bc4j.xcfg file. This work real good for accepting username/password credentials dynamically, since we have multiple database in one computer I have to accept DSN name and if possible built my own configuration file.

ORA-04030: out of process memory when using Java Stored Procedures

Hello,
I have a problem using Java Stored Procedures in Oracle 10g.
My Java application performs http posts to a webservice and the response is parsed in order to populate some DB tables.
There is a scheduled job which calls the Java Stored Procedure every x minutes.
No matter of the 'x minutes' values - after about 160 - 200 calls I get this error:
ORA-04030: out of process memory when trying to allocate 1048620 bytes (joxp heap,f:OldSpace)
ORA-04030: out of process memory when trying to allocate 2097196 bytes (joxp heap,f:OldSpace)
The job stops just while is posting the http request. The weird thing is that almost each time the first http post request I get this error:
java.net.ConnectException: Connection refused
     at java.net.PlainSocketImpl.socketConnect(Native Method)
     at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:305)

So, The out of process memory occured each time just before getting such an error, and I suspect to be a connection between these errors.
Tech details:
1. OS: WinXP
2. Oracle 10.1.0.2.0
3. To perform http post I use HttpClient 3.1 from Apache.
4. I checked the http connection to be closed each time, and this is done.
5. I checked the oracle statement and connection to be closed each time and this is done
6. The JVM error (logged in .trc files of Oracle) is:

Can be a problem with JVM threading under Oracle ?

The server prcess failed to allocate more memory for large objects ( in Oldspace).
If you Google ORA-04030, you will see several recommendations to work around this.
The Java VM in the database already has HttpClient, i don't know why you are loading the Apache HttpClient but this might not be the surce of the problem.
