Passing data from Oracle stored procedures to Java

We're going to write a new web interface for a big system based on Oracle database. All business rules are already coded in PL/SQL stored procedures and we'd like to reuse as much code as possible. We'll write some new stored procedures that will combine the existing business rules and return the final result dataset.
We want to do this on the database level to avoid java-db round trips. The interface layer will be written in Java (we'd like to use GWT), so we need a way of passing data from Oracle stored procedures to Java service side. The data can be e.g. a set of properties of a specific item or a list of items fulfilling certain criteria. Would anyone recommend a preferable way of doing this?
We're considering one of the 2 following scenarios:
passing objects and lists of objects (DB object types defined on the schema level)
passing a sys_refcursor
We verified that both approaches are "doable", the question is more about design decision, best practice, possible maintenance problems, flexibility, etc.
I'd appreciate any hints.

I'd appreciate any hints.If logic is already written in DB, and the only concern is of passing the result to java service side, and also from point of maintenance problem and flexibility i would suggest to use the sys_refcursor.
The reason if Down the line any thing changes then you only need to change the arguments of sys_refcursor in DB and as well as java side, and it is much easier and less efforts compare to using and changes required for Types and Objects on DB and java side.
The design and best practise keeps changing based on our requirement and exisiting design. But by looking at your current senario and design, i personally suggest to go with sys_refcursor.

Fill a pdf form with data using Java code

Hi,
Modern formats of Acrobat ".pdf" files allows to define form fields.
I have a datasource, let's say in a database.
I want to fill my ".pdf" with my database-stored data automatically, and want to write Java code for that.
1. What is the best way to achieve this ?
2. Is it necessary to install Acrobat Distiller server and if so what web services should I invoke ? Where is the doc ?
3. Are there efficient Java libraries to do so ?
Thank you for helping... As ever, this is kind of an emergency case
Have a good day.
Phil

Take a look at the FDF Toolkit for Java:
http://www.adobe.com/devnet/acrobat/fdftoolkit.html
That will allow you to, through Java, construct an FDF that contains all your form data. You then add a reference to your "template" PDF file in the FDF as well and send the FDF to the client. Acrobat will open the FDF, see the reference to the PDF, open the PDF and then merge any data contained in the FDF with the PDF.

Calling Stored Procedures from JAVA Application

Hi all,
i am using JDeveloper 3.2.2 for creating a DB Application that
uses Oracle8i as DB Server.
One approach of the application is to only use PL/SQL Stored
Procedures to write Data back to the DB.
Some of the stored procedures expect more than 20 parameters.
I want to know if there is a better way to call such a stored
procedure from Java than using a CallableStatement and setting
its 20 parameters.
Another reason why the way above isnt possible for me is that
i need a dynamic way to set the parameters of the stored
procedure.
A solution for that dynamic way i could think of is to get
the information of the stored procedure by using some functions
of DatabaseMetaData and than use this information to map the
parameters with their respective variables in the java
application.
The best argument against this way is that it would be time and
performance consuming.
So could anybody tell me a solution to call PL/SQL stored
procedures from java which is better than doing something like:
String calString = "{Call myStoredProc(";
while(counter < 22) {
params += "?";
if(counter<21) params += ",";
counter++;
calString += params + ")}";
try {
CallableStatement cs = session.prepareCall(calString);
} catch(SQLException ex) { ... }
cs.setString(1, var1);
cs.setString(1, var2);
And that for every Stored Procedure i want to call ?!?
Any help or direction-leading would be really appreciated.
Tank you much.
MfG,
Oliver Bankel

Hi Oliver,
If you your Stored Procedures were in Java and seamlessly
integrated with your Java application would that make your life
easier?
I don't know if this is a practical or acceptable solution in
your environment but it would certainly solve all of your issues
and provide your with a couple of nice advantages. Scalability
and platform independence are just a couple I could think of.
There is a tool called in2j (see http://www.in2j.com) which will
automatically migrate your PL/SQL Stored Procedures into Java.
You can download a copy of the tool and migrate your PL/SQL to
Java with no upfront costs. If you're happy with the generated
Java and want to deploy it, the migration fee falls due - simple.
Hope this helps.

DB2 Stored Procedure from Java-JDBC

Hi All,
I am using DB2 stored procedure which have been written in COBOL. I have two types of stored procedures. First types of stored procedure takes IN parameter and returns OUT parameter. These stored procedures are working fine. The second type of stored procedure takes IN parameter and returns a CURSOR. According to Database team (who wrote these stored procedure) claims that they can see data in a cursor when they test these stored procedure directly in the database. However, when I run these stored procedures from Java code it returns NULL ResultSet. Here is the code:
public SearchResult getAllBenefitHEDType(SearchParameter searchParam) throws DAOException {
log.debug(" getAllBenefitHEDType method - entering ");
HashMap searchParametersMap = searchParam.getHashMap();
SearchResult searchResult = new SearchResult();
String type = (String) searchParametersMap.get(UDFConstant.LOOKUP_SEARCH_TYPE);
HashMap resultParametersMap = new HashMap();
ArrayList resultSetDTO = new ArrayList();
try {
conn = this.getConnection();
conn.setAutoCommit(false);
System.out.println("getAllBenefitHEDType Step 1");
CallableStatement cs = conn.prepareCall("{call TEST.APS003(?)}"); // Stored Procedure with one IN parameter.
cs.setString(1,type);
boolean retVal = cs.execute(); // this should return true if ResultSet is available.. in my case it is returning false.
// I tried with getting the Object
ResultSet rs = (ResultSet) cs.getObject(1); // this should give me a valid result set ... in my case I am getting null
if (rs!=null) {
System.out.println("getAllBenefitHEDType Step 4A Result Set Not Null");
} else {
System.out.println("getAllBenefitHEDType Step 4A Result Set Is Null");
// I tried getting the resultset
ResultSet rs1 = cs.getResultSet(); // this should give me a valid result set ... in my case I am getting null
if (rs1!=null) {
System.out.println("getAllBenefitHEDType Step 4D Result Set Not Null");
} else {
System.out.println("getAllBenefitHEDType Step 4D Result Set Is Null");
while (rs.next()) {
System.out.println("getAllBenefitHEDType Step 5");
LookupDTO lookupDTO = new LookupDTO();
// the following code populate the Lookup DTOs from ResultSet.

A few comments...
1) Creating tables, particularly tables whose names seem to imply that they are temporary tables, on the fly in a stored procedure is a bad idea. That is not the way to work with Oracle, though it is a common practice in other databases like SQL Server. There is undoubtedly a better way to do this in Oracle if you can explain what you're trying to accomplish from a business standpoint.
2) If you are going to use dynamic SQL, you almost always want to use bind variables, not literals. One of the quickest ways to kill an Oracle database's performance is to not use bind variables.
3) As has already been mentioned, assuming FH_INICIO is a DATE column, you need to put an explicit TO_DATE around your strings in order to convert them to dates. Otherwise, Oracle's implicit cast depends on the session's NLS_DATE_FORMAT, which is likely to be different in different client applications and from different client machines.

It appears you are trying to store java objects (types) in a database rather than raw data (string, int, date types) that the object contains. If so, I don't think that ever really caught on. Most programmers store the raw data, then pull it out and populate a class. The problem with storing the object is that new versions of classes come out and your old version is stored in the database. If you just store the data, you don't have to worry about what version is in the database. You can populate the new version of the class with the same data.
Also, others can use sql to query your data and use it for their own use independent of what you intended it for. I think most people use the (browser) based utility that comes with the database to create the tables, normalize them, set up primary keys, set up foreign keys, etc rather then run an sql statement as you did above.

Hi Guys,
Dont forget to close your stmt and connection after execution
Use this as a template if you like:
try{
     /**make connection**/
     ServerConnection sc = new ServerConnection();
Statement stmt = sc.conn.createStatement();
/**create statement & execute**/
String insertstmt = "insert into .......";
//execute
stmt.execute(insertstmt);
/**Close and catch exception**/
stmt.close();
sc.conn.close();
catch(SQLException sqlE){
     sqlE.printStackTrace();
     System.out.println(sqlE.getMessage());
As for the string "insertstmt" itself, this is where your standard SQL statement goes
So get it working using a standard SQL editor first, then copy and paste it in to this string variable. The string should be a series of concatenated strings and variables to recreate the SQL atatement in Java. For example
the SQL statement:
insert into Mytable(SESSIONID, TIME1) values ('300', '4.45pm' );
assuming the values are stored in variables called 'sessionnumber' and 'time'
will become
String stmt =
"insert into Mytable(SESSIONID, TIME1) values ('"+sessionnumber+"', '"+time+"')";
Hope this helps.
E
Ps. Do a system.out.println after you create the stmt. The statement printed out to the console should be a valid SQL statement that you can use in your editor. (minus the ;)
...keep working on the string until you can do this.

Want to get data from java file

Hi,
I am creating a program using JBuilder. All is going fine but im having trouble reading data. Well, I want to read data from a java program which is in the same package of my program but when i wrote the command to read it i get a Exception saying:
"java.io.FileNotFoundException: dataControl2.java (The system cannot find the file specified)"
Below is the program i wrote to do this:
The hole point of my program is to get temporary stored data from my conrol program that stores the data and saves it to a file. This program needs to get the user name and password and if the password is enabled or not.
try {
FileInputStream fi = new FileInputStream("dataControl2.java");
ObjectInputStream oi = new ObjectInputStream(fi);
dataControl2 dat = (dataControl2) oi.readObject();
jTextField1.setText("" + dat.userName);
if (dat.usePassword == 1) {
jPasswordField1.setEditable(false);
usePassword = 1;
oi.close();
} catch (Exception e) {
jTextField1.setText("" + e.toString());
I understand that the file cant be found, that wasnt hard to work out, but the thing is that the file does exist so i think i have wrote me program wrong.
If you can see wat i have done wrong or wish to learn more about my query email me at:
[email protected]
or
[email protected]
Many Thanks,
Tom

well, i did that and this is what my program looks like now:
try {
File aFile = new File("dataControl2.java");
System.out.println("absolute path : " + aFile.getAbsolutePath());
FileInputStream fi = new FileInputStream(aFile);
ObjectInputStream oi = new ObjectInputStream(fi);
dataControl2 dat = (dataControl2) oi.readObject();
jTextField1.setText("" + dat.userName);
if (dat.usePassword == 1) {
jPasswordField1.setEditable(false);
usePassword = 1;
oi.close();
} catch (Exception e) {
jTextField1.setText("" + e.toString());
System.out.println("");
System.out.println("" + e);
Well, now i get a message saying that the file is corrupted.
I have really screwed this up but i really need to get this fixed.
If possible i can zip my java program and send it to you if you ask!

Creating Stored Procedure in Java

Hi All,
I would like to ask how to create a stored procedure in Java.
My project now is to create a program that will open a DB2 SQL File (Creating Table and Stored Procedure) and then Execute it.
Executing the CREATE TABLE command is not that difficult since I can break the execution down by statement (divide by ";" in the SQL file).
The logic I applied here are:
1. Open the SQL file and store the contents into a String object.
2. Call the executeUpdate(string_sql_fileContent) method of Statement Object.
Example: SQL File contect to be executed.

I can divide this by ";" and execute them by statement.
But my problem is when creating Stored Procedure... Since in stored procedure there are so many stub-statements...
Example: Content of SQL File for creating stored procedure.
===========================================================
CREATE PROCEDURE MDMTEST.DROP_ALL_OBJECTS ( )
SPECIFIC MDMTEST.SQL051109115453000
LANGUAGE SQL
NOT DETERMINISTIC
CALLED ON NULL INPUT
MODIFIES SQL DATA
INHERIT SPECIAL REGISTERS
BEGIN
     Delete Statement;
     Insert Statement;
     Update Statement;
END;
===========================================================
Take note there are three statements inside the CREATE..BEGIN.. and END.. (namely Delete, Insert, and Update Statements).
How can I execute the command for creating the procedure in Java? I believe that creating stored procedures in other databases are almost the same...
So... anyboby who have tried creating stored procedure in Java?
Please help me in this... I wanna pass the subject hehe..

I have used these files as a sample:
Java Program:

InvokeAll on off-heap stored data

I'm using a distributed cache with partitioned off-heap storage because all the data can't be contained in the heap memory. However, profiling the heap memory still show the storage worker threads still have enormous amounts of data in memory even after GC's.
So that's why I was wondering what happens, when you do something like
myCache.invokeAll(new EqualsFilter("someProperty", "someValue"), new MyEntryProcessor());and there's no index on "someProperty".
When the storage containing node receives the invocation request, it must get all stored data from off-heap memory to heap memory to filter it and optionally apply the EP to it.
How does it do that? Does it end up loading all data in heap memory? The filtered and unfiltered ones? Or is the processing done entry per entry only keeping a reference to the entry being filtered and processed by the EP?
I'm using Coherence 3.5.3 patch5.
Regards
Jan

Hi Jan,
user10601659 wrote:
Hi Robert,
so what you're saying is that suppose I have 1000 objects in the cache and 500 of them match my filter, those 500 objects need to fit in my heap space when I do cache.invokeAll(Filter, EntryProcessor).
Potentially all 500 may need to fit (e.g. if they are in the same partition). Also, I suspect, besides the Java form, the Binary version of the object also will need additional capacity while you are executing the processAll method.
If this holds true, wouldn't it be a workaround to use a PartitionedFilter or a LimitFilter and invoke the EntryProcessor per partition or per #objects? This way the number of matching objects can be reduced.
Regards
JanYou can use PartitionedFilter or LimitFilter or whatever approach to break down data processed at the same time to more manageable chunks. The main problem with this multiple roundtrip approach is that cached data may change between getting the individual chunks, so you get weaker consistency across those chunks. (Data in individual chunks will not necessarily be consistent with each other). Whether this is a problem for you or not, is something which only you can decide. Whatever you do, cross partition guarantees may not be provided anyway, but if chunking only by numbers, you may lose consistency for data residing within a single partition, too.
Best regards,
Robert

SAP paging overflow when storing data in the ABAP/4 memory.

I am trying to create a data source in BI7.0 in the Datawarehousing Workbench. But along the process when i need to select a view i get an error detailed in the following error file extract: Please go through and assist.
untime Errors MEMORY_NO_MORE_PAGING
Date and Time 06.06.2009 14:21:35
Short text
SAP paging overflow when storing data in the ABAP/4 memory.
What happened?
The current program requested storage space from the SAP paging area,
but this request could not be fulfilled.
of this area in the SAP system profile.
What can you do?
Note which actions and input led to the error.
For further help in handling the problem, contact your SAP administrator
You can use the ABAP dump analysis transaction ST22 to view and manage
termination messages, in particular for long term reference.
Error analysis
The ABAP/4 runtime system and the ABAP/4 compiler use a common
interface to store different types of data in different parts of
the SAP paging area. This data includes the
ABAP/4 memory (EXPORT TO MEMORY), the SUBMIT REPORT parameters,
CALL DIALOG and CALL TRANSACTION USING, as well as internally defined
macros (specified with DEFINE).
To store further data in the SAP paging area, you attempted to
allocate a new SAP paging block, but no more blocks were
available.
When the SAP paging overflow occurred, the ABAP/4 memory contained
entries for 20 of different IDs.
Please note:
To facilitate error handling, the ABAP/4 memory was
deleted.
How to correct the error
The amount of storage space (in bytes) filled at termination time was:
Roll area...................... 8176
Extended memory (EM)........... 13587912
Assigned memory (HEAP)......... 0
Short area..................... " "
Paging area.................... 40960
Maximum address space.......... " "
By calling Transaction SM04 and choosing 'Goto' -> 'Block list',
you can display an overview of the current roll and paging memory
levels resulting from active users and their transactions. Try to
decide from this whether another program requires a lot of memory
space (perhaps too much).
The system log contains more detailed information about the
termination. Check for any unwanted recursion.
Determine whether the error also occurs with small volumes of
data. Check the profile (parameter "rdisp/PG_MAXFS", see
Installation Guidelines).
Is the disk or the file system that contains the paging file
full to the extent that it cannot be increased, although it has
not yet reached the size defined in the profile? Is the
operating system configured to accommodate files of such a
size?
The ABAP processor stores different types of data in the SAP
paging area. These include:
(1) Data clusters (EXPORT ... TO MEMORY ...)
(2) Parameters for calling programs (SUBMIT REPORT ...),
Dialog modules (CALL DIALOG ...) and transactions
(CALL TRANSACTION USING ...)
(3) Internally defined program macros (DEFINE ...)
Accordingly, you should check the relevant statements in a program
that results in an overflow of the SAP paging area.
It is critical when many internal tables, possibly with
different IDs, are written to memory (EXPORT).
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"MEMORY_NO_MORE_PAGING" " "
"SAPLWDTM" or "LWDTMU20"
"TABC_ACTIVATE_AND_UPDATE"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.
Restrict the time interval to 10 minutes before and five minutes
after the short dump. Then choose "System->List->Save->Local File
(Unconverted)".
3. If the problem occurs in a problem of your own or a modified SAP
program: The source code of the program
In the editor, choose "Utilities->More
Utilities->Upload/Download->Download".
4. Details about the conditions under which the error occurred or which
actions and input led to the error.

Hi Huggins,
Maintenance of the Paging File is owned by your basis team.
They should increase this in order for your transaction to process successfully.
Just for your reference, in case the OS used is windows server 2003, paging file value can be checked through;
Right click in the My Computer>properties.
Then go to Advance tab;
Then there should be a performance section, click the settings
Then Advance tab again. The paging file can be seen from there.
(and can be adjusted from there also)
The value of the paging file in general will be dependent with the available RAM from the hardware.
Hope this helps. Thanks a lot.

Report Script returns no data and "java.io.FileNotFoundException" error

When attempting to write to a new file (Eg: C:\TEST.txt), Report Script returns no data and "java.io.FileNotFoundException" error occurs.
This error occurs only in Essbase 9.3.1.3 release, however it works fine in release 9.3.1.0.
After running the report the script, it pops up the follwing message:
"java.io.FileNotFoundException: ..\temp\eas17109.tmp (The system cannot find the file specified): C:\TEST.txt"
When checked the TEST.txt, it was empty.

Sorry folks, I just found out the reason. Its because there was no data in the combination what I was extracting.
but is this the right error message for that? It should have atleast create a blank file right?
