How to pass Array of Java objects to Callable statement

Hi ,
I need to know how can I pass an array of objects to PL/SQL stored procedure using callable statement.
So I am having and array list of some object say xyz which has two attributes string and double type.
Now I need to pass this to a PL/SQL Procedure as IN parameter.
Now I have gone through some documentation for the same and found that we can use ArrayDescriptor tp create array (java.sql.ARRAY).
And we will use a record type from SQL to map this to our array of java objects.
So my question is how this mapping of java object's two attribute will be done to the TYPE in SQL? can we also pass this array as a package Table?
Please help
Thanks

I seem to remember that that is in one of Oracle's online sample programs.

Passing Array of java objects to and from oracle database-Complete Example

Hi all ,
I am posting a working example of Passing Array of java objects to and from oracle database . I have struggled a lot to get it working and since finally its working , postinmg it here so that it coudl be helpful to the rest of the folks.
First thinsg first
i) Create a Java Value Object which you want to pass .
create or replace and compile java source named Person as
import java.sql.*;
import java.io.*;
public class Person implements SQLData
private String sql_type = "PERSON_T";
public int person_id;
public String person_name;
public Person () {}
public String getSQLTypeName() throws SQLException { return sql_type; }
public void readSQL(SQLInput stream, String typeName) throws SQLException
sql_type = typeName;
person_id = stream.readInt();
person_name = stream.readString();
public void writeSQL(SQLOutput stream) throws SQLException
stream.writeInt (person_id);
stream.writeString (person_name);
ii) Once you created a Java class compile this class in sql plus. Just Copy paste and run it in SQL .
you should see a message called "Java created."
iii) Now create your object Types
CREATE TYPE person_t AS OBJECT
EXTERNAL NAME 'Person' LANGUAGE JAVA
USING SQLData (
person_id NUMBER(9) EXTERNAL NAME 'person_id',
person_name VARCHAR2(30) EXTERNAL NAME 'person_name'
iv) Now create a table of Objects
CREATE TYPE person_tab IS TABLE OF person_t;
v) Now create your procedure . Ensure that you create dummy table called "person_test" for loggiing values.
create or replace
procedure give_me_an_array( p_array in person_tab,p_arrayout out person_tab)
as
l_person_id Number;
l_person_name Varchar2(200);
l_person person_t;
l_p_arrayout person_tab;
errm Varchar2(2000);
begin
     l_p_arrayout := person_tab();
for i in 1 .. p_array.count
loop
     l_p_arrayout.extend;
     insert into person_test values(p_array(i).person_id, 'in Record '||p_array(i).person_name);
     l_person_id := p_array(i).person_id;
     l_person_name := p_array(i).person_name;
     l_person := person_t(null,null);
     l_person.person_id := l_person_id + 5;
     l_person.person_name := 'Out Record ' ||l_person_name ;
     l_p_arrayout(i) := l_person;
end loop;
p_arrayout := l_p_arrayout;
     l_person_id := p_arrayout.count;
for i in 1 .. p_arrayout.count
loop
insert into person_test values(l_person_id, p_arrayout(i).person_name);
end loop;
commit;
EXCEPTION WHEN OTHERS THEN
     errm := SQLERRM;
     insert into person_test values(-1, errm);
     commit;
end;
vi) Now finally create your java class which will invoke the pl/sql procedure and get the updated value array and then display it on your screen>Alternatively you can also check the "person_test" tbale

     catch(Exception SQLe) {
                    System.out.println("IN EXCEPTION BLOCK ");
                    return null;
and thats it. you are done.
Hope it atleast helps people to get started. Comments are appreciated. I can be reached at ([email protected]) or [email protected]

Hi Sunil,
I've a similar situation where I'm trying to insert Java objects in db using bulk insert. My issue is with performance for which I've created a new thread.
http://forum.java.sun.com/thread.jspa?threadID=5270260&tstart=30
I ran into your code and looked into it. You've used the Person object array and directly passing it to the oracle.sql.ARRAY constructor. Just curios if this works, cos my understanding is that you need to create a oracle.sql.STRUCT out of ur java object collection and pass it to the ARRAY constructor. I tried ur way but got this runtime exception.
java.sql.SQLException: Fail to convert to internal representation: JavaBulkInsertNew$Option@10bbf9e

                    at JavaBulkInsertNew.main(JavaBulkInsertNew.java:76)
Here's a code snippet I used :
Object optionVal[] =   {optionArr[0]};   // optionArr[0] is an Option object which has three properties
oracle.sql.ArrayDescriptor empArrayDescriptor = oracle.sql.ArrayDescriptor.createDescriptor("TT_EMP_TEST",conn);
ARRAY empArray = new ARRAY(empArrayDescriptor,conn,optionVal);If you visit my thread, u'll see that I'm using STRUCT and then pass it to the ARRAY constructor, which works well, except for the performance issue.
I'll appreciate if you can provide some information.

How to pass xml data as objects into Database using store procedures

Hi All,
     I don't have much knowledge on store procedure,can anybody help how to pass the xml as objects in Database using store procedure.
My Requirement is I have a table with three fields EMPLOYEE is table name and the fields are EMP_ID,EMP_TYPE AND EMP_DET,I have to insert the employees xml data into corresponding fields in the table.
Input Data
<ROWSET>
   <ROW>
     <EMP_ID>7000</EMP_ID>
      <EMP_TYPE>TYPE1</EMP_TYPE>
     <EMP_DET>DEP</EMP_DET>
<ROW>
<ROW>
     <EMP_ID>7000</EMP_ID>
     <EMP_TYPE>TYPE2</EMP_TYPE>
    <EMP_DET>DEP2</EMP_DET>
<ROW>
<ROW>
     <EMP_ID>7000</EMP_ID>
     <EMP_TYPE>TYPE3</EMP_TYPE>
    <EMP_DET>DEP3</EMP_DET>
<ROW>
<ROWSET>
So each row values has to inserted into resp fields in the table.

Do you have a similar structure in your stored procedure ?
In that case you can simply call the procedure from soa using db adapter and do a mapping to assign the values.

How to pass array into xslt from java

i have a xslt in which i am passing some parameter from java there is one parameter which is a array in java which i need to pass becouse array length is not defined so that xslt will work dynakically according to the parameter.
right now i am passing parameter but not able to send the array parameter that's why my code is not fully dynamic
please give suggestion.
anagh

it is not possible to pass array by using XSLT, you can wirite all values into a String with certain delim symbol, pass this string, then use xsl.substring() to get different values.

ORA-00932 when trying to pass ARRAY from Java SP to PL/SQL

Hi all
I am trying to pass ARRAYs back and forth between PL/SQL and Java stored procedures. But I keep getting:
ORA-00932: inconsistent datatypes: expected a return value that is an instance of a user defined Java class convertible to an Oracle type got an object that could not be converted
Here's my PL/SQL:
create or replace type CONTENTP.sentences_array as VARRAY(1000) of CLOB
-- I've also tried .. as TABLE of CLOB and varray/table of VARCHAR2
declare
proc_clob CLOB;
arr SENTENCES_ARRAY;
begin
SELECT document_body
into proc_clob
from documents
where document_id = 618784;
arr := processdocument.sentencesplit (proc_clob);
end;

FUNCTION removeHTML(Param1 CLOB)
return CLOB

LANGUAGE java

end;
Java sentenceSplit code:
public static oracle.sql.ARRAY sentenceSplit ( CLOB text) throws IOException, SQLException
Connection conn = new OracleDriver().defaultConnection();
String[] arrSentences = sent.getsentences ( CLOBtoString (text) );
ArrayDescriptor arrayDesc =
ArrayDescriptor.createDescriptor ("SENTENCES_ARRAY", conn);
ARRAY ARRSentences = new ARRAY (arrayDesc, conn, arrSentences);
return ARRSentences;
I have confirmed that the String[] arrSentences contains a valid string array. So the problem seems to be the creation and passing of ARRSentences.
I have looked at pages and pages of documents and example code, and can't see anything wrong with my declaration of ARRSentences. I'm at a loss to explain what's wrong.
Thanks in advance - any help is much appreciated!

How to parse XML to Java object... please help really stuck

Thank you for reading this email...
If I have a **DTD** like:
<!ELEMENT person (name, age)>
<!ATTLIST person
     id ID #REQUIRED
>
<!ELEMENT name ((family, given) | (given, family))>
<!ELEMENT age (#PCDATA)>
<!ELEMENT family (#PCDATA)>
<!ELEMENT given (#PCDATA)>
the **XML** like:
<person id="a1">
<name>
     <family> Yoshi </family>
     <given> Samurai </given>
</name>
<age> 21 </age>
</person>
**** Could you help me to write a simple parser to parse my DTD and XML to Java object, and how can I use those objects... sorry if the problem is too basic, I am a beginner and very stuck... I am very confuse with SAXParserFactory, SAXParser, ParserAdapter and DOM has its own Factory and Parser, so confuse...
Thank you for your help, Yo

Hi, Yo,
Thank you very much for your help. And I Wish you are there...I'm. And I plan to stay - It's sunny and warm here in Honolulu and the waves are up :)
A bit more question for dear people:
In the notes, it's mainly focus on JAXB,
1. Is that mean JAXB is most popular parser for
parsing XML into Java object? With me, definitely. There are essentially 3 technologies that allow you to parse XML documents:
1) "Callbacks" (e.g. SAX in JAXP): You write a class that overrides 3 methods that will be called i) whenever the parser encounters a start tag, ii) an end tag, or iii) PCDATA. Drawback: You have to figure out where the heck in the document hierarchy you are when such a callback happens, because the same method is called on EACH start tag and similarly for the end tag and the PCDATA. You have to create the objects and put them into your own data structure - it's very tedious, but you have complete control. (Well, more or less.)
2) "Tree" (e.g. DOM in JAXP, or it's better cousin JDOM): You call a parser that in one swoop creates an entire hierarchy that corresponds to the XML document. You don't get called on each tag as with SAX, you just get the root of the resulting tree. Drawback: All the nodes in the tree have the same type! You probably want to know which tags are in the document, don't you? Well, you'll have to traverse the tree and ask each node: What tag do you represent? And what are your attributes? (You get only strings in response even though your attributes often represent numbers.) Unless you want to display the tree - that's a nice application, you can do it as a tree model for JTree -, or otherwise don't care about the individual tags, DOM is not of much help, because you have to keep track where in the tree you are while you traverse it.
3) Enter JAXB (or Castor, or ...): You give it a grammar of the XML documents you want to parse, or "unmarshall" as the fashion dictates to call it. (Actually the name isn't that bad, because "parsing" focuses on the input text while "unmarshalling" focuses on the objects you get, even though I'd reason that it should be marshalling that converts into objects and unmarshalling that converts objects to something else, and not vice versa but that's just my opinion.) The JAXB compiler creates a bunch of source files each with one (or now more) class(es) (and now interfaces) that correspond to the elements/tags of your grammar. (Now "compiler" is a true jevel of a misnomer, try to explain to students that after they run the "compiler", they still need to compile the sources the "compiler" generated with the real Java compiler!). Ok, you've got these sources compiled. Now you call one single method, unmarshall() and as a result you get the root node of the hierarchy that corresponds to the XML document. Sounds like DOM, but it's much better - the objects in the resulting tree don't have all the same type, but their type depends on the tag they represent. E.g if there is the tag <ball-game> then there will be an object of type myPackage.BallGame in your data structure. It gets better, if there is <score> inside <ball-game> and you have an object ballGame (of type BallGame) that you can simply call ballGame.getScore() and you get an object of type myPackage.Score. In other words, the child tags become properties of the parent object. Even better, the attributes become properties, too, so as far as your program is concerned there is no difference whether the property value was originally a tag or an attribute. On top of that, you can tell in your schema that the property has an int value - or another primitive type (that's like that in 1.0, in the early release you'll have to do it in the additional xjs file). So this is a very natural way to explore the data structure of the XML document. Of course there are drawbacks, but they are minor: daunting complexity and, as a consequence, very steep learning curve, documentation that leaves much to reader's phantasy - read trial and error - (the user's guide is too simplicistic and the examples too primitive, e.g. they don't even tell you how to make a schema where a tag has only attributes) and reference manual that has ~200 pages full of technicalities and you have to look with magnifying glas for the really usefull stuff, huge number of generated classes, some of which you may not need at all (and in 1.0 the number has doubled because each class has an accompanying interface), etc., etc. But overall, all that pales compared to the drastically improved efficiency of the programmer's efforts, i.e. your time. The time you'll spend learning the intricacies is well spent, you'll learn it once and then it will shorten your programming time all the time you use it. It's like C and Java, Java is order of magnitude more complex, but you'd probably never be sorry you gave up C.
Of course the above essay leaves out lots and lots of detail, but I think that it touches the most important points.
A word about JAXB 1.0 vs. Early Release (EA) version. If you have time, definitively learn 1.0, they are quite different and the main advantage is that the schema combines all the info that you had to formulate in the DTD and in the xjs file when using the EA version. I suggested EA was because you had a DTD already, but in retrospect, you better start from scratch with 1.0. The concepts in 1.0 are here to stay and once your surmounted the learning curve, you'll be glad that you don't have to switch concepts.
When parser job is done,
what kind of Java Object we will get? (String,
InputStream or ...)See above, typically it's an object whose type is defined as a class (and interface in 1.0) within the sources that JABX generates. Or it can be a String or one of the primitive types - you tell the "compiler" in the schema (xjs file in EA) what you want!
2. If we want to use JAXB, we have to contain a
XJS-file? Something like:In EA, yes. In 1.0 no - it's all in the schema.
I am very new to XML, is there any simpler way to get
around them? It has already take me 4 days to find a
simple parser which give it XML and DTD, then return
to me Java objects ... I mean if that kind of parser
exists....It'll take you probably magnitude longer that that to get really familiar with JAXB, but believe me it's worth it. You'll save countless days if not weeks once you'll start developing serious software with it. How long did it take you to learn Java and it's main APIs? You'll either invest the time learning how to use the software others have written, or you invest it writing it yourself. I'll take the former any time. But it's only my opinion...

How to pass a populated Java bean to a jsp

Hi,
I'm new to J2EE world. I want to know how should I pass a populated Java Bean (not EJB) to a JSP without displaying that JSP in the next step. I would be much grateful to anyone who gives a solution to my problem.
Thanks in advance
With best regards
Sampath

> I'm new to J2EE world. I want to know how should I

Urk?
A JSP is meant to be displayed. If there's business logic in that JSP, get it out of there. Process the bean as needed on the server side and send the flow on to some view that actually should be displayed.

How to pass any type of objects into Portal's rules engine?

Is that possible to pass any type of objects into Portal's rules engine? Or BEA's Portal service rules engine can only allow to pass a limited number of objects?
Are there any information about BEA's rules engine? and Can we use its rules engine without using its Portal service?
Thank you.

I worked on BEA rules engine 4 months back. I'm sure you can pass any JAVA object to it's working meomory. I am giving my sample rules here, hope it will be helpful for you.
I just replace pcakage name, other than that everything is from wroking project. Open in xml spy, it should be clear from the desc. If you have any questions post back.

How to force OTT generating java objects?

I've read in an Oracle white paper that Oracle has an Object Type Translator (ott) utility that creates java objects from object type definitions in the database. In my installations of Oracle 8.1.7 and 9.2i my ott utility only supports output of C structures (though in ott.exe present such strings as "public void...", "throws SQLException..."). Does anyone know how to force ott.exe generating java objects?

OTT can generate C structures or C++ classes from object definitions. You should look at JPublisher for Java classes.

How can i delete an java object immediately?

Is there any mechanism that delete an object immediately?
I know I can delete an java object by GC mechanism, but it can not be effective immediately.
is there any other solutions?
thanks -:)

And you did an internet search to try and find out how to delete Java from your computer? Well, this forum is for Java programmers, people who write programs using the Java language. Not for people who use those programs. But it was a good try.
The easiest thing for you to do is just to leave Java on your computer. It won't do any harm (aside from taking up a bit of space on your disk) and if you go to a web site that contains an applet, it might even be useful. Maybe that's why you got the link in the first place.
If you really want to get rid of it, then go into Control Panel and use Add and Remove Programs to do that. (It's called something else in Vista, I forget what, hope you didn't get stuck with that.) But I would still suggest leaving it on your computer.

Pass arrays from Java to PL/SQL procedure.

Hi All,
Can some body give an example, where an array of strings is passed from java to a PL/SQL procedure.
Any help in this regard is appreciated.
Thanks,
Prashant

will be disabled.
But by setting RemoveInfectedConnectionsEnabled to false, we can ask weblogic
to return the Physical Connection to Pool. I have tested this with the attached
code. I DON'T find any issue.Good. The only real risk to obtaining the physical connection is retaining and
using it beyond the current thread execution. Your code looks OK. The only thing
I'd suggest is to add to the finally block. I would put a separate try-catch-ignore
block around every action in the finally, so if one fails, the others are still
done.
As long as you're writing good JDBC like that, there is no risk to telling the
pool to trust the code, by setting RemoveInfectedConnectionsEnabled to false.
That way you'll retain all the performance of the pools.

I want your opinion in this, so that I will be confident in using this feature

Note : Please look at the sample code that I am using. I AM NOT GOING TO USE PHYSICAL
CONNECTIONS for normal operations. I will use Physical Connection only when I
want to pass Arrays to Oracle.
Thanks
