Java in Stored Procedures

Hi all,
This is the Problem i am facing. Can anyone help please !!!!
I hv creaeted a java source file to print "Hello World" and compiled to create java class file. Now i hv both the .java and .class file under the directory c:\suresh\javaexam.
I tried loading the java file to the database using loadjava utility. I hv not done any modifications to the classpath or anything. I had jdk installed prior to Oracle installation in my machine.
The loadjava utility generates the following error message
unable to initialize threads : cannot find class java/class/thread. Could not create Java VM.
Here is the command i tried.
loadjava -u scott/tiger -resolve c:\suresh\javaexam\Dba.java.
Then i included all the jar files in jdk directory in the jreclasspath of loadjava.bat and tried the command again. Even then it is giving the same problem.
Can anyone please help me to overcome this ?
Problem 2.
I used Create Java command to load java in RDBMS. But when checked with user_objects, the status says Invalid. --- Why is this shows Invalid ? How to make it Valid ?
Advance Thanks for the Reply.
my e-mail id : [email protected]
Regards
PB Suresh

What is the Java version you are using. Is it 1.1.X or 1.2.X?
The loadjava command is a batch file on nt.
Set the CLASSPATH from the command line to the following.
set CLASSPATH=c:\jdk1.1.8\lib\classes.zip;c:\orant\jdbc\lib\classes111.zip;.
Now run the loadjava.

Java call stored procedure with nested table type parameter?

Hi experts!
I need to call stored procedure that contains nested table type parameter, but I don't know how to handle it.
The following is my pl/sql code:
create or replace package test_package as
type row_abc is record(
col1 varchar2(16),
col2 varchar2(16),
col3 varchar2(16 )
type matrix_abc is table of row_abc index by binary_integer;
PROCEDURE test_matrix(p_arg1 IN VARCHAR2,
p_arg2 IN VARCHAR2,
p_arg3 IN VARCHAR2,
p_out OUT matrix_abc
END test_package;
create or replace package body test_package as
PROCEDURE test_matrix(p_arg1 IN VARCHAR2,
p_arg2 IN VARCHAR2,
p_arg3 IN VARCHAR2,
p_out OUT matrix_abc
IS
v_sn NUMBER(8):=0 ;
BEGIN
LOOP
EXIT WHEN v_sn>5 ;
v_sn := v_sn + 1;
p_out(v_sn).col1 := 'col1_'||to_char(v_sn)|| p_arg1 ;
p_out(v_sn).col2 := 'col2_'||to_char(v_sn)||p_arg2 ;
p_out(v_sn).col3 := 'col3_'||to_char(v_sn)||p_arg3 ;
END LOOP ;
END ;
END test_package ;
My java code is following, it doesn't work:
Class.forName ("oracle.jdbc.driver.OracleDriver");
Connection con = DriverManager.getConnection
("jdbc:oracle:thin:@10.16.102.176:1540:dev", "scott", "tiger");
con.setAutoCommit(false);
CallableStatement ps = null;
String sql = " begin test_package.test_matrix( ?, ? , ? , ? ); end ; ";
ps = con.prepareCall(sql);
ps.setString(1,"p1");
ps.setString(2,"p2");
ps.setString(3,"p3");
ps.registerOutParameter(4,OracleTypes.CURSOR);
ps.execute();
ResultSet rset = (ResultSet) ps.getObject(1);
error message :
PLS-00306: wrong number or types of arguments in call to 'TEST_MATRIX'
ORA-06550: line 1, column 8:
PL/SQL: Statement ignored
Regards

Louis,
If I'm not mistaken, record types are not allowed. However, you can use object types instead. However, they must be database types. In other words, something like:
create or replace type ROW_ABC as object (
col1 varchar2(16),
col2 varchar2(16),
col3 varchar2(16 )
create or replace type MATRIX_ABC as table of ROW_ABC
/Then you can use the "ARRAY" and "STRUCT" (SQL) types in your java code. If I remember correctly, I recently answered a similar question either in this forum, or at JavaRanch -- but I'm too lazy to look for it now. Do a search for the terms "ARRAY" and "STRUCT".
For your information, there are also code samples of how to do this on the OTN Web site.
Good Luck,
Avi.

Can't publish java xml stored procedure

I have written a java class to return values from the database as XML using the XSU, and am attempting to publish the class as a stored procedure. I have successfully created other java stored procedures, but am continually getting the following error on this one:
ORA-29531: no method getItems in class foo/bar/Inbox
To illustrate the interface which I am trying to implement, snippets from the java class and the Oracle package follow:
===========================================
Java class:
package foo.bar;
import oracle.sql.CLOB;
import other.stuff;
public class Inbox {
public static void getItems(int userID,
CLOB[] xml)
===========================================
Oracle package spec:
PROCEDURE getItems(user_id IN PLS_INTEGER,
buf IN OUT NOCOPY CLOB);
Package body:
PROCEDURE getItems(user_id IN PLS_INTEGER,
buf IN OUT NOCOPY CLOB)
AS LANGUAGE JAVA NAME
'foo.bar.Inbox.getItems(java.lang.Integer,
oracle.sql.CLOB[])';
===========================================
I originally structured the class to return the CLOB, but altered the structure to handle the CLOB as an IN OUT parameter so that the NOCOPY option modifier could be used, as suggested in S. Muench's book. I was surprised to hear that Oracle creates an in-memory copy of the return value from a function (wish I'd known this before).
All suggestions appreciated.
null

When I use JDeveloper's automatic Java Stored Procedure publishing feature, I get a PL/SQL spec that looks like this:
CREATE OR REPLACE PACKAGE EXPERIMENTALWORK
AUTHID CURRENT_USER AS
PROCEDURE GETITEMS ("userID" IN NUMBER,
"xml" IN OUT CLOB)
AS LANGUAGE JAVA
NAME 'foo.bar.Inbox.getItems(int, oracle.sql.CLOB[])';
END EXPERIMENTALWORK;You still have to add the NOCOPY by hand, but perhaps the int versus java.lang.Integer is significant?

PL/SQL vs. Java stored procedures.

After learning about PL/SQL I have to admit it looks ugly to me. Is there any concrete reasons why PL/SQL should be used over Java for stored procedures. I understand that PL/SQL is native to Oracle and procedures written in PL/SQL would probably out perform Java procedures, but what if performance was not the most critical issue. Looking at PL/SQL makes me think it would be hard to maintain.
Thanks in advance.

Hi
There is a common mis-understanding here. 2008 will be the last year oracle is going to support Developer in Client server mode. Oracle does not claim to discontinue Developer, They are currently working on Developer Rel9i, which is truely a multi tiered archtecture. PLSQL will live as long as Oracle database lives.
PLSQL is simple yet powerful language, it is getting better with each version. With the new 9i release, it is truely object oriented like any OO language like Java/C etc. Further you can override methods in Objects and override them in C, Java, PLSQL etc. What this means is that you can have a parent Object and have some method x implemented in PLSQL, you can then inherit another object from the parent object and override the same method x, this time you can write the method x in java or C. No other language can offer this feature. Further PLSQL also provides you with dynamic typing, like most other OO languages. These are some of the features of PLSQL.
And ofcourse, the language you choose is purely a matter of choice. If you are going to write a database-centric application, PLSQL might be a right choice as it facilitates many things for us like exception handling, transaction etc.
If you are writing a generic application that can interact with any database, then java might be a right choice as you and encapsulate the information in the language.

Export Java-based external stored procedure

I've got a properly deployed external Java-based stored procedure deployed properly. I can see it by querying user_objects as well as user_java_classes. Is there any way I can export it so that I can deploy it in a different database? Please note that I mean a different way than performing a complete export, I just want to selectively export this external procedure.
Thanks, Tom

I would think that the following would work:
expdp user/password directory=my_dir dumpfile=java.dmp include=java_source
This would export the java source for the user performing the export. If you need to export java_source for another user, you would have to add
schemas=other_schema
Adding the other schema would only work if the user running the job was privileged.

MySQL/j Stored procedure on Server Failure? is it a bug? workaround?

Hi all, with the release of SE 6 pending, I thought that this issue should be addressed. As I'm not sure if it's a bug or not, I decided to post in this forum to see if anybody has haad experience with it, has a workaround or any other information that could be usefull.
The issue:
MySQL v5.x offers stored procedures. the MySQL/j connector has the ability to call these procedures.
If you run the stored procedure localy through Java, the stored procedure executes perfectly.
Once deployed onto a server, and the stored procedures on the same server in a mysql database and "ALL PRIVILAGES" including "EXECUTE ROUTINE" are granted. The stored procedure fails to run.
The error returned by the mysql/j connector is this :
"Driver requires declaration of procedure to either contain a 'nbegin' or 'n' to follow argument declaration, or SELECT privilege on mysql.proc to parse column types."
Here is a link to a MySQL forum about the issue:
http://forums.mysql.com/read.php?98,67532,67532#msg-67532
So it appears that it is a java issue.
Is there a workaround?
Has anybody successfully been able to use Java with MySQL stored Procedures?? (Pretty sad if we havn't)
Any help on this topic would be greatly appreciated.
cheers!

Yes, I read through the threads, that is Why I cam here after posting back with MySQL trying all the suggeestions, I still can't find the thread from the MySQL/J developer, I did find the one from a MySQL developer though.
We can't actually change permissions oursevles with our currecnt Servlet host.
So they changed permissions for us:
We checked to see if we had permissions, All permissions are granted for the localhost.
currently not sure how to check them for the '%' assignment
Our host also tried to drop the procedurees and create them again with the invoker command, but this was also to no avail.
I was also sure that it was a MySQL issue, but was hoping someobody had another method of a workaround.
It seems to be something to do with Java wanting the metadata for registering output variables.

How to pass the parameter values to the stored procedure from java code?

I have a stored procedure written in sqlplus as below:
create procedure spInsertCategory (propertyid number, category varchar2, create_user varchar2, create_date date) AS BEGIN Insert into property (propertyid, category,create_user,create_date) values (propertyid , category, create_user, create_date); END spInsertCategory;
I am trying to insert a new row into the database using the stored procedure.
I have called the above procedure in my java code as below:
CallableStatement sp = null;
sp = conn.prepareCall("{call spInsertCategory(?, ?, ?, ?)}");
How should I pass the values [propertyid, category, create_user, create_date) from java to the stored procedure?[i.e., parameters]
Kindly guide me as I am new to java..

Error while executing java stored procedure from a pl/sql procedure

We have a requirement where we need to execute JAVA code stored in an Oracle database (Java Stored Procedure). This code uses some JAR files which we have already loaded without any errors in the database.
The class file was also loaded in the database without any errors. But when we execute the method of this class (JAVA code), it gives the following error:
ORA-29532: Java call terminated by uncaught Java exception:
java.lang.NoClassDefFoundError
Is there any way of debugging the code and getting to know where exactly the problem is? Or, any tool/software available for doing the same.
Any pointers would be of great help!
Thanks in advance

Hi Uday,
My guess is that there is a problem with your java stored procedure that is causing the "ExceptionInInitializer" error to be thrown. According to the javadoc:
is thrown to indicate that an exception occurred during
evaluation of a static initializer or
the initializer for a static variable
Since I didn't see any of your code in your post, I can't help you much more, I'm afraid. Perhaps if you would provide some more details, I may be able to help you some more. I think the following details would be helpful:
1. Complete error message and stack trace you are getting.
2. The section of your java code that you think is causing the problem.
3. Oracle database version you are using.
Good Luck,
Avi.

Unable to access Custom UDTs returned from a Java Stored Procedure

Hi,
I have a UDT in the DB :-
create type contactrecord as object (
CN_ID NUMBER(8),
CN_TITLE VARCHAR2(40),
CN_FIRST_NAME VARCHAR2(25)
and this is the corresponding java class ContactDetails.java that maps to this UDT, that I loaded in the Aurora VM.
package package1;
mport java.sql.SQLData;
import java.sql.SQLException;
import java.sql.SQLInput;
import java.sql.SQLOutput;
public class ContactDetails implements SQLData
private String sql_type;
private long CN_ID;
private String CN_TITLE;
private String CN_FIRST_NAME;
public String getSQLTypeName() throws SQLException
return this.sql_type;
//implementation of readSql
public void readSQL(SQLInput stream, String typeName) throws SQLException
sql_type = typeName;
CN_ID = stream.readLong();
CN_TITLE = stream.readString();
CN_FIRST_NAME = stream.readString();
public void writeSQL(SQLOutput stream) throws SQLException
stream.writeLong(CN_ID);
stream.writeString(CN_TITLE);
stream.writeString(CN_FIRST_NAME);
//getters and setters for the class vars go here.....
There is another class A.java that has a java stored procedure/function, which I loaded into the Aurora VM
Here is the class.
package package1;
public class A
public static ContactDetails returnObject(String name )
ContactDetails cd = new ContactDetails();
cd.setCN_ID(1);
cd.setCN_FIRST_NAME(name);
return cd;
Then I declared the call spec for A.returnObject() as
FUNCTION returnObject(name varchar2) return contactrecord
AS LANGUAGE JAVA
NAME 'package1.A.returnObject(java.lang.String) return package1.ContactDetails';
Then I tried to call the function returnObject through JDBC calls from a class in another VM.
When I access the object returned by the function, I get a null object.
Here is the Client code:
CallableStatement cs = null;
ResultSet rs = null;
try
cs = conn.prepareCall("{ ? = call returnObject(?) }");
java.util.Map map = conn.getTypeMap();
map.put("ADMIN.CONTACTRECORD", Class.forName("package1.ContactDetails"));
conn.setTypeMap(map);
cs.registerOutParameter(1, OracleTypes.STRUCT, "ADMIN.CONTACTRECORD");
cs.setString(2, "John Doe" );
cs.execute();
ContactDetails cd = (ContactDetails)cs.getObject(1);
System.out.println("contact first name is:-"+cd.getCN_FIRST_NAME()); //Null Pointer here..cd is null....:(
if (cs != null) cs.close();
catch(Exception e)
e.printStackTrace();
Although If I try to access the same function from a pl/sql block, I am able
to access the contactrecord fields.
What could be wrong ..???
I could not find any error with the object mapping, as it works perfectly when I interact directly from my VM to the DB,
without going thru the aurora VM.
I am using a OCI driver to connect to the DB via JDBC.
Thanx in advance for any help at all.

Shahid,
I too have had bad luck in many cases with the automatic translation of Java types to PL/SQL and back. I think the SYS package on the PL/SQL side which handles some of the conversion is DBMS_PICKLER (there are equivalent Java classes which do the same in that world and seem to execute automagically when a conversion is needed). You might want to double-check the data type mappings against the DOC on OTN to make sure they map 1-1. Also make sure the permissions are granted against your objects to whoever is executing them, etc. Very often, I've resorted to passing simple scalar types between the two languages as in some cases the results with complex types are inconsistent.
Sorry this isn't much help,
-Dan

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:

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.

Speed test: PL/SQL vs. Java Stored Procedures

I performed tests on these two procedures:
===========================================
// Create a Statement
Statement stmt = conn.createStatement (ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
// Query the table
ResultSet rset = stmt.executeQuery ("select SIFOB, SIFRA_GU from sezko");
while (rset.next ()) {
salary = rset.getInt(1);
rset.updateInt (1, salary + 1);
salary = rset.getInt(2);
rset.updateInt (2, salary + 1);
rset.updateRow();
} // while
conn.commit();
// Close the RseultSet
rset.close();
// Close the Statement
stmt.close();
===========================================
procedure updateTable is
cursor c_updateTable is select rowid, SIFOB, SIFRA_GU from sezko;
begin
for r_updateTable in c_updateTable loop
update sezko set SIFOB = SIFOB + 1, SIFRA_GU = SIFRA_GU + 1 where rowid = r_updateTable.rowid;
end loop;
commit;
end;
===========================================
First procedure is written in Java (as Java Stored procedure) and second is PL/SQL.
Java is about 10x slower than PL/SQL code.
Can you explain bad performance results?
thank you

Hi,
I suppose the problem is not with the connection object,but with make connection to the database for every executeupdate or executeupdaterow called .Similarly for fetching the data from the database you
can use the fetch size technique.Please check the 8.1.6 Java Developers guide for using this.

Calling the Java Method in PL/SQL Java Stored procedure errors out

Hi,
I could not find a suitable thread to post my PL/SQL question so iam posting it here.........
I have written a java class by name XYZ which has a method ABC for which there are 9 arguements being passed and its a VOID method.
This java class has been loaded into ORACLE using DBMS_JAVA.LOADJAVA pkg, Now this class is being called in the oracle as a JAVA Stored procedure...... When ever im trying to call the procedure it throws the following error

Java stored procedure vs. PL-SQL vs. external java program

Hi,
I'm using a stored procedure for running a query and a few consequent updates. Currently I'm using Java stored procedure for that, which was my choice for simplicity on one hand, and running with the DB on the other.
In my tests, strangely enough it came out that running as java stored procedure was 3-4 times slower than running as a java program outside the database. I don't know how to explain this, and I wonder if switching to PL/SQL will improve the performance of the code.
Any experiences? recommendations?
Thanks,
Dawg

In my tests, strangely enough it came out that running as java stored procedure was 3-4 times slower than running as a java program outside the database. I don't know how to explain this, and I wonder if switching to PL/SQL will improve the performance of the code.This isn't strange at all. See: Oracle's JVM (Aurora) is an independent Java Virtual Machine implementation, in accordance to specification. It implements all necessary parts of it (I think so). When you use an external JVM (I assume it's Sun's HotSpot JVM) you use completely different product. It is implemented in different way, it has many different code parts.
One of the biggest differences between Oracle's JVM and Sun's JVM is [Just-in-Time compiler|http://en.wikipedia.org/wiki/Just-in-time_compilation]. Oracle has implemented it only in the 11g version of database, i.e. 2 years ago, while Sun performed it back in 2000 and continues to improve it for the last 9 years. That would explain obvious differences between Java program inside and outside the DB: they are executed in absolutely different worlds. Diffs could be up to 10x times or more - that's not unusual.
If you are on 10g and want to compare performance of stored Java procedure vs external program, then you might use additional command-line instruction for external program to disable JIT:
-XintPS. I wouldn't use Java for your task - that's a total overkill. Use simple SP instead.

Empty strings when passing a Java object to a Stored Procedure

Hi,
I'm using the interface SQLData to pass Java objects to StoredProcedures. All the object's attributes 'arrive' to the Stored Procedure ok, except the strings, which are empty.
Here is my Oracle object:
TYPE OBJ_ASJFF_OBJ1 IS OBJECT (
ARG1 CHAR(3),
ARG2 NUMBER(4),
ARG3 CHAR(4),
ARG4 NUMBER(7),
ARG5 NUMBER(13,2),
ARG6 CHAR(1));
The nested table of that object:
TYPE TAB_ASJFF_OBJ1 AS TABLE OF OBJ_ASJFF_OBJ1;
The procedure declaration:
PROCEDURE Pup_Instaura_Processo (                              x_crCert IN TAB_ASJFF_OBJ1,
x_cResult OUT CHAR(4)
My SQLData implementation:
public void writeSQL(SQLOutput stream) throws SQLException {
               stream.writeString(getArg1());
               stream.writeInt(getArg2().intValue());
               stream.writeString(getArg3());
               stream.writeLong(getArg4().longValue());
               stream.writeBigDecimal(getArg5());
               stream.writeString(getArg6());
Can anybody help me?
Thanks in advance

not exactly what you wanted but ingredients can be found at
- JPublisher's docuemntation (especially "Type Mapping Support Through PL/SQL Conversion Functions")
- http://otn.oracle.com/sample_code/tech/java/jsp/Oracle9iJSPSamples.html (Best Hotels PL/SQL Sample )
- http://otn.oracle.com/tech/xml/xdk_sample/xdksample_093001i.html
hope this helps

I have a Java Stored procedure which takes an instance of a different java object as its parameter.
I need to do this from a pl/sql package - can anyone point me to a sample etc (looked on the website but don't see one) ?
