Passing array of Types to java class

I am trying to pass a user defined type (that is an array) from PL/Sql to a javaclass. Here are the definitions that make-up the parameter to pass from PL/Sql to Java (uri_digest_array):
CREATE OR REPLACE TYPE uri_digest as object (uri VARCHAR2(256),
digest_value CLOB);
CREATE OR REPLACE TYPE uri_digest_array AS VARRAY(10) OF uri_digest;
In Oracle-land, java classes are published to PL/Sql by way of the following definition. Note that the intent here is to have compatible data-types.
CREATE OR REPLACE FUNCTION SIGNRETURNINGXML (p_array IN uri_digest_array)
RETURN LONG
AS LANGUAGE JAVA
NAME 'SignReturningXml.main(oracle.sql.Array) return java.lang.String';
Here is a fragment of the java class code:
class SignReturningXml {
public static String main(String [] [] signItems ) // I have no idea what datatype to use here!
{ . . . . The code in here would process the passed array normally from first entry to last.
Currently I get the following error:
PLS-00311: the declaration of
"SignReturningXml.main(oracle.sql.Array) return
java.lang.String" is incomplete or malformed
I could use some suggestions on resolving the datatype conflicts. Any ideas? Has anyone tried this kind of thing?
Thanks,
Michael

Michael,
At the risk of another [non] useful response, I meant that you should try searching the "Ask Tom" Web site, because usually you will find an answer to your question that has already been asked by someone else. Perhaps these will be helpful:

Trying to pass Oracle array/object type to Java

I have a Java class with two inner classes that are loaded into Oracle:

    public static class TextObject
        public String font_name;

        public int bottom_pos;
        public int leading;
        public TextObject[] column_texts;
}I have object types in Oracle as such that bind to the Java classes:

/I successfully (as far as I know) build a PDFJ_COLUMN_ARRAY object in a PL/SQL procedure. The PDFJ_COLUMN_ARRAY contains PDFJ_COLUMN objects; each of those objects contains a PDFJ_TEXT_ARRAY of PDFJ_TEXT objects (Example: pdf_column_array(i).pdf_text_array(i).text_string := 'something';). In this procedure, I pass this PDFJ_COLUMN_ARRAY as a parameter to a Java function. I assume the Java function parameter is supposed to be a oracle.sql.ARRAY object.
I cannot figure out how to decompose this generic ARRAY object into a ColumnObject[] array. I also tried Googling and searching the forums, but I can't figure out matching search criteria. I was wondering if anyone here knows anything about passing user-defined Oracle type objects to a Java function and retrieving the user-defined Java class equivalents that they are supposedly mapped to--especially a user-defined array type of user-defined object types containing another user-defined array type of user-defined object types.

Ok. I will try asking on the JDBC forum. So, don't
flame me for cross-posting. :PWe won't, if over there you just post basically a

Using oracle.sql.BLOB data type in Java Class to pass in a Blob

All,
I'm trying to pass in a BLOB from PL/SQL to a Java Class, but the BLOB isn't passed correctly.
When I check the length of the BLOB in PL/SQL its different from the length of the BLOB in java.
I'm using DB 11g and the ojdbc5.jar file in my java classes.
The java function uses the oracle.sql.BLOB type to get the parameter.
The java class is loaded into the DB and called via a PL/SQL function.
Kind regards,
Nathalie

The question is indeed a little ambigious defined ;o)
When I pass the BLOB to the java method and invoke BLOB.getBytes() and then get the length of the BLOB in java the length of the BLOB is bigger than in PL/SQL.
When I use the method 'getBinaryStream' and write this to a buffer, the code works.
I will log a tar regarding the getBytes()-method to ask for more detailed information regarding the methods provided using the JDBC Drivers.
Kind regards,
Nathalie

Arrays that work with Java Class

Good Day all.
Currently, I am working on a program that is giving me a bit of trouble starting...can anyone give me assistance and try to tell me what I am doing incorrectly?
Here is the tasking:
Main Method
1. Output statement to screen saying this program will accept hours worked for 3 employees.
2. Declare an Integer Array to hold 3 employees hours. Call this array "employees"
3. Main Method then calls inputData Method (Passing array as argument) do not accept any return value.
4. Main Method then calls outputData Method (Passing array as argument) do not accept any return value.
import java.util.*;
import java.text.DecimalFormat;
public class Arrays
{ /*This starts the Arrays*/
     public static void main (String[] args)
     Scanner scannerObject = new Scanner(System.in);
     Scanner keyboard = new Scanner(System.in);
inputData(employees);
     System.out.println("This program will accept hours worked for 3 employees.");
     String[]employees = new String [3];

How am I coming along....I started with the MAIN Method...Now I have started and created a MONSTER with this other portion of my program
Main Method
1. Output statement to screen saying this program will accept hours worked for 3 employees.
2. Declare an Integer Array to hold 3 employees hours. Call this array "employees"
3. Main Method then calls inputData Method (Passing array as argument) do not accept any return value.
4. Main Method then calls outputData Method (Passing array as argument) do not accept any return value.
InputData Method (Receives Arrary)
1. Gers input using a for loop for each employees hours into the array elements.
2. Prompt the user with the following phrase. Enter hours worked for employee #: (Where # is the employee number 1-3)
Can anyone tell me what is going god awfully wrong with this program? LAUGHING

How to return Values from Oracle Object Type to Java Class Object

Hello,
i have created an Oracle Object Types in the Database. Then i created Java classes with "jpub" of these types. Here is an example of the type.
CREATE OR REPLACE TYPE person_type AS OBJECT
ID NUMBER,
vorname VARCHAR2(30),
nachname VARCHAR2(30),
geburtstag DATE,
CONSTRUCTOR FUNCTION person_type RETURN SELF AS RESULT,
CONSTRUCTOR FUNCTION person_type(p_id NUMBER) RETURN SELF AS RESULT,
CONSTRUCTOR FUNCTION person_type(p_vorname VARCHAR2,
p_nachname VARCHAR2,
p_geburtstag DATE) RETURN SELF AS RESULT,
MEMBER FUNCTION object_exists(p_id NUMBER) RETURN BOOLEAN,
MEMBER PROCEDURE load_object(p_id NUMBER),
MEMBER PROCEDURE save_object,
MEMBER PROCEDURE insert_object,
MEMBER PROCEDURE update_object,
MEMBER PROCEDURE delete_object
MEMBER PROCEDURE load_object(p_id NUMBER) IS
BEGIN
SELECT p.id, p.vorname, p.nachname, p.geburtstag
INTO SELF.ID, SELF.vorname, self.nachname, SELF.geburtstag
FROM person p
WHERE p.id = p_id;
END;
My problem is, that if i use the member function "load_object" from my java app it doesnt return the selected values to the java class and i dont know why. I use the java class like this:
PersonObjectType p = new PersonObjectType();
p.load_object(4);
There is a reocrd in the database with id = 4 and the function will execute successful. But if i try to use "p.getVorname()" i always get "NULL". Can someone tell me how to do that?
Thanks a lot.

CallableStatement =
"DECLARE

BEGIN
a.load_object(4);
? := a;
END;"
And register as an out parameter.

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.

Sql type to Java class?

I want to write a utility class to generate a java source file (bean) from out of the metadata of a database table. the metadata returns the column type as a java.sql.Types constant (int value). now, i want to map these int values to Java classes. (e.g. Types.INT => java.lang.Integer). Is there already such a method in the API or do i have to write my own switch ... case Types.INT ... result = Integer.class ... method?

well, i wrote my own utility method to generate such beans:

Passing array of objects from java to oracle.

Hi,
We have the following structure in oracle.
We have a nested table type of varchar2(50).
type var_tab is table of varchar2(50);
We have one object type with one member as varchar2 and another one as var_tab type.
type attribute_obj is object(
attrib_name varchar2(100)
,attrib_val var_tab
Then we have table type of that object type,
type table_tab is table of attribute_obj;
Then we have one object type with one member as varchar2,another member as integer and another one as table_tab type.
type prod_obj is object(
pr_name varchar2(100), tb_flag integer
,pr_attrib table_tab
Then we have table type of this object type,
type prod_tab as table of prod_obj;
So, the total structure is something like this;
'OS','OS_NAME', 'Windows'
'Linux'
'UNIX'
'OS_VERSION','XP'
'RED HAT'
'SOLARIS'
so, basically we have
x prod_tab:=prod_tab();
x(3):=prod_obj('OS',0,table_tab(attribute_obj('OS_NAME',var_tab('Windows','Linux','UNIX')),attribute_obj('OS_VERSION','XP','RED HAT','SOLARIS'))));
And this how we call the procedure ---
all_prod_comb_pkg.sp_main(x)
The procedure deifinition is -
procedure sp_main ( p_prod_arr prod_tab);
Please suggest a way so that we can implement the same structure in Java and then call the procedure using that array of objects.
regards,
Dipankar.

Dipankar,
There's a separate example of how to map Oracle OBJECTs to JDBC STRUCTs.
Study that one and combine the two. Not difficult (in my opinion :-)
Or search the JDBC forum for the words "STRUCT" and "ARRAY".
(What, you want me to do your coding for you?)
Good Luck,
Avi.

Parameter passing from JSF to a Java class

Hi,
I am new to JSF, and I looked around in the questions to find an answer to my "Parameter passing" question. No luck..
Below is an example that illustrate what I mean:
This illustrate a way that I have found to work:
<h:commandButton value="New"
disabled="#{buttonHandler.newDisabled}" />
<h:commandButton value="Delete"
disabled="#{buttonHandler.deleteDisabled}" />
But something like this is more how I would prefer to do it:
<h:commandButton value="New"
disabled="#{buttonHandler.Disabled("New")}" />
<h:commandButton value="Delete"
disabled="#{buttonHandler.Disabled("Delete")}" />
Yes, I know it does not work.. but it illustrates what I want to do. I would like to use the same Java method for all buttons and just pass a parameter to sort out which one it is.
Someone knows how to achieve this?

In the get(key), you can pass in object, and do
whatever you want with it. That's exactly what you
want, but maynot be as nice, but that's EXACTLY what
you want I think, except you have to work with get
function, not your function. But you can just call
your function in the get function.(Shudder) Really, "hack" is too kind for this.
So to continue my checksum example above: I can "easily" find the checksum of an object by creating an implementation of Map that really only implements the get() method and throws a method-not-implemented exception for all other methods (violating the rule that all classes implementing Map should follow Map semantics). Then I create a getChecksum() method on my backing bean, which returns this Map adapter and allows me to property-bind+map-bind to:
#{myBean.checksum[myObject]}
Now for every single method I want to implement, I have to create a whole new class that implements Map but really isn't a Map! Horrors! And this assumes, as you later note, that I only want to use one parameter---never more. Of course, for mutiple parameters, I could always create a map of maps, with each sub-map another custom class implementing Map just so that it can represent another parameter and allow:
#{myBean.checksum[myObject][myColor][myWeight]}
Disgusting---a fake semantics-violating map class for each parameter?
Can someone who designed JSF let us know why in the world that we can't pass parameters to a method?

Mapping SQL data types (especially SMALLINT) to Java classes

I want to know the reason for a certain pair of exceptions in JDBC�s mapping of SQL data types to Java classes.
Sun�s web site ( http://java.sun.com/j2se/1.4.2/docs/guide/jdbc/getstart/mapping.html ), Sybase�s site, and other sites contain mappings from SQL data types to Java primitive data types and/or Java classes. On that Sun web page, Section 9.9.1 maps mostly to Java primitive data types, and Section 9.9.3 maps mostly to Java classes. For the SQL data types that map to both primitive data types and classes, the class is typically the wrapper class of the primitive data type. For example, SQL�s DOUBLE data type maps to both the double primitive data type and its wrapper class (Double). However, Section 9.7 of that Sun web page says that there are exceptions for SQL�s TINYINT and SMALLINT. As expected, they map to the byte and short primitive data types, but they map to the Integer class, not the Byte and Short classes (which are the wrapper classes for byte and short). The web page does not state the reason for this pair of exceptions. It seems to me that SMALLINT data would either work for both short and Short or fail for both short and Short. I don�t see why it would work for short but fail for Short (as the web page implies).
Can anybody think of a reason for the pair of exceptions? Thanks.

1) If a DBMS deals with the short and byte primitive data types (as the various web pages imply that it does), then why would it not deal with the Short and Byte wrapper classes?As another guess, because conversions get a little weird in java. Or at least they did in the past. As I recall (with not a lot of clarity) it is possible to do something like pass a perfectly valid string value into a short and get an exception. Whereas using Integer and then converting to Short works.
Keep in mind that these are guesses.
3) What I really want to know is this: If I use wrapper classes of Short and Byte (instead of Integer), what will be the harmful consequences (IF ANY)? So far, I have done some trivial testing with a Short for a SMALLINT column (I have not yet tried any TINYINT columns), and it seems to be working.I considered it risky to not test all target databases and drivers.
Obviously testing will reveal problems.
If you don't want to test then you might want to stick with integers.

How can I execute a java class with arguments from an air application built from mxml?

I have an mxml application. It has a button, and when that button select event occurs, I want my mxml air app to pass arguments to a java class I have built, which resides in a package path on my system. I need to be able to pass several arguments to my java method from my mxml call. How do I do this, and what config files are necessary? For the simple task I want to engineer, can you show me an example of a properly configured config file? My java class has been executed at the command line in the past as follows:
java -cp %CP% com.abc.prism.queue.EmitMessage XYZ "my message text" 192.12.13.14 5672
where %CP% is an env variable that tells my class the classpath it runs with, and XYZ, "my message text", the IP address, and the port are the arguments I must pass from mxml to my java class. How do I accomplish this?
How do I make known to the java class I call from mxml the %CP% class path? It tells my java class where to find various rabbitMQ jars.

Hi,
You need to use Integration technology like BlazeDS or LCDS.

Using RichOutputText value in a java class

Hi to everybody. I'm using Jdeveloper 11g and I'm developing an application that shows a tree in a jsp page. The java class that implements tree component need to receive a value written in a RichOutputText in the same Jsp page. Is it possible to do it? If yes, how can i realize it?
Thank's a lot

The problem is that when i try to pass RichOutputText value to the java class that implements the tree, one error occurs:

Passing Array of Srings between Visual Basic and Labview dll

I have searched and searched for the correct way to pass an array of
strings between Visual Basic 6.0 and a Labview 7 dll. So far, I still
do not know how to pass the array. When I create the dll in LV, the
array of strings is presented as a string, not an array. I am familiar
with passing arrays of type double, but I really need to know how to
pass an array of strings. Any and all help is appreciated.
Bob

Hey Bob,
From what I understand, that can get kind of messy. You have to allocate the memory in VB in the format that LabVIEW expects (see the externalcode.h file in National Instruments\LabVIEW 7.0\cintools for details). Then pass a pointer to that location to LabVIEW. There are a couple of related examples online. They don't necessarily show how to pass an array of strings to VB, but they should show how to pass a string and an array. I hope this helps.

Pass an array of a user defined class to a stored procedure in java

Hi All,
I am trying to pass an array of a user defined class as an input parameter to a stored procedure. So far i have done the following:
Step 1: created an object type.
CREATE TYPE department_type AS OBJECT (
DNO NUMBER (10),
NAME VARCHAR2 (50),
LOCATION VARCHAR2 (50)
Step 2: created a varray of the above type.
CREATE TYPE dept_array1 AS TABLE OF department_type;
Step 3:Created a package to insert the records.
CREATE OR REPLACE PACKAGE objecttype
AS
PROCEDURE insert_object (d dept_array);
END objecttype;
CREATE OR REPLACE PACKAGE BODY objecttype
AS
PROCEDURE insert_object (d dept_array)
AS
BEGIN
FOR i IN d.FIRST .. d.LAST
LOOP
INSERT INTO department
VALUES (d (i).dno,d (i).name,d (i).location);
END LOOP;
END insert_object;
END objecttype;
Step 4:Created a java class to map the columns of the object type.
public class Department
private double DNO;
private String Name;
private String Loation;
public void setDNO(double DNO)
this.DNO = DNO;
public double getDNO()
return DNO;
public void setName(String Name)
this.Name = Name;
public String getName()
return Name;
public void setLoation(String Loation)
this.Loation = Loation;
public String getLoation()
return Loation;
Step 5: created a method to call the stored procedure.
public static void main(String arg[]){
try{
Department d1 = new Department();
d1.setDNO(1); d1.setName("Accounts"); d1.setLoation("LHR");
Department d2 = new Department();
d2.setDNO(2); d2.setName("HR"); d2.setLoation("ISB");
Department[] deptArray = {d1,d2};
OracleCallableStatement callStatement = null;
DBConnection dbConnection= DBConnection.getInstance();
Connection cn = dbConnection.getDBConnection(false); //using a framework to get connections
ArrayDescriptor arrayDept = ArrayDescriptor.createDescriptor("DEPT_ARRAY", cn);
ARRAY deptArrayObject = new ARRAY(arrayDept, cn, deptArray); //I get an SQLException here
callStatement = (OracleCallableStatement)cn.prepareCall("{call objecttype.insert_object(?)}");
((OracleCallableStatement)callStatement).setArray(1, deptArrayObject);
callStatement.executeUpdate();
cn.commit();
catch(Exception e){
System.out.println(e.toString());
I get the following exception:
java.sql.SQLException: Fail to convert to internal representation
My question is can I pass an array to a stored procedure like this and if so please help me reslove the exception.
Thank you in advance.

OK I am back again and seems like talking to myself. Anyways i had a talk with one of the java developers in my team and he said that making an array of structs is not much use to them as they already have a java bean/VO class defined and they want to send an array of its objects to the database not structs so I made the following changes to their java class. (Again hoping some one will find this useful).
Setp1: I implemented the SQLData interface on the department VO class.
import java.sql.SQLData;
import java.sql.SQLOutput;
import java.sql.SQLInput;
import java.sql.SQLException;
public class Department implements SQLData
private double DNO;
private String Name;
private String Location;
public void setDNO(double DNO)
this.DNO = DNO;
public double getDNO()
return DNO;
public void setName(String Name)
this.Name = Name;
public String getName()
return Name;
public void setLocation(String Location)
this.Location = Location;
public String getLoation()
return Location;
public void readSQL(SQLInput stream, String typeName)throws SQLException
public void writeSQL(SQLOutput stream)throws SQLException
stream.writeDouble(this.DNO);
stream.writeString(this.Name);
stream.writeString(this.Location);
public String getSQLTypeName() throws SQLException
return "DOCCOMPLY.DEPARTMENT_TYPE";
Step 2: I made the following changes to the main method.
public static void main(String arg[]){
try{
Department d1 = new Department();
d1.setDNO(1);
d1.setName("CPM");
d1.setLocation("LHR");
Department d2 = new Department();
d2.setDNO(2);
d2.setName("Admin");
d2.setLocation("ISB");
Department[] deptArray = {d1,d2};
OracleCallableStatement callStatement = null;
DBConnection dbConnection= DBConnection.getInstance();
Connection cn = dbConnection.getDBConnection(false);
ArrayDescriptor arrayDept = ArrayDescriptor.createDescriptor("DEPT_ARRAY", cn);
ARRAY deptArrayObject = new ARRAY(arrayDept, cn, deptArray);
callStatement = (OracleCallableStatement)cn.prepareCall("{call objecttype.insert_array_object(?)}");
((OracleCallableStatement)callStatement).setArray(1, deptArrayObject);
callStatement.executeUpdate();
cn.commit();
catch(Exception e){
System.out.println(e.toString());
and it started working no more SQLException. (The changes to the department class were done manfully but they tell me JPublisher would have been better).

Shiraz

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;
PROCESSDOCUMENT package definition:
CREATE OR REPLACE PACKAGE CONTENTP.PROCESSDOCUMENT AS
FUNCTION sentenceSplit(Param1 CLOB)
return SENTENCES_ARRAY
AS
LANGUAGE java
NAME 'com.contentp.documents.ProcessDocument.sentenceSplit(oracle.sql.CLOB) return oracle.sql.ARRAY';
FUNCTION removeHTML(Param1 CLOB)
return CLOB
AS
LANGUAGE java
NAME 'com.contentp.documents.ProcessDocument.removeHTML(oracle.sql.CLOB) return oracle.sql.CLOB';
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!
