How to load java clasess first time in oracle database?

hi
I want to load my java compiled class to oracle database.
whenever I load it using loadjava ( command line utility) it gives me ora-904 error. column not found. while creating class as schema object in database.
1. How to check that oracle database is JAVA enabled?
2. If I run initjvm.sql script to enable java in Oracle,
then also it is giving same problem?
3. DBMS_JAVA package is also NOT in the database.
What should i do for these cases?
waiting for ur response.
I am using oracle 8i 8.1.7 datbase.

Hi!
If it was working before and you are on the same BB, I suggest doing these steps:
Full reboot:
With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation.
If that does not restore the delivery of your emails, then re-push your service books:

Lastly, since it's HotMail, it may be that you have not done the recently required re-validation:
http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalId=KB13137
Hopefully one of those will work!

I don't have any experience with GTO's cards, but one would expect they provide a user guide or a data sheet how to load applications.. Reasons could be:
1. Issuer policy to have a certain security level for content management --> raise the security level to C_MAC + ENC
2. Issuer policy this card is static --> no post-issuance

Problem while inserting Date/Time in Oracle Database

Hai,
i want to insert the date and time in a date column. here, i am using java.sql.Date and java.sql.Time to assign the date in Prepared Statement.
PreparedStatement psmt=con.prepareStatement("insert into test(ex_date) values(?)");
java.util.Calendar c=Calendar.getInstance();
c.set(2002,2,21,10,10,00);
java.sql.Date d=new Date(c.getTime().getTime());
java.sql.Time t=new Time(c.getTime().getTime());
psmt.clearParameters();
psmt.setDate(1,d);
psmt.setDate(1,t);
psmt.executeUpdate();
Above program is inserted the Date and time in the database as the following "1900/2/21 10:10 AM"
but i am giving the year as 2002. it inserted the year as 1900. what is the problem with the code?
please let me know
Thanks in advance.
Regards
sankarjune14

Hai Franco,
i put the wrong code. Here, is the Original Code.
PreparedStatement psmt=con.prepareStatement("insert into test(ex_date) values(?)");
java.util.Calendar c=Calendar.getInstance();
c.set(2002,2,21,10,10,00);
java.sql.Date d=new Date(c.getTime().getTime());
java.sql.Time t=new Time(c.getTime().getTime());
psmt.clearParameters();
psmt.setDate(1,d);
psmt.setTime(1,t); // Last time i put psmt.setDate(1,t);
psmt.executeUpdate();
and, the getTimeInMillis() method is a protected method in java.util.Calendar class. how can we use it
please give me some other idea to insert the date and time in oracle database.
Thanks in advance

How to configure portal server with the Backend Oracle database

Hi Portal Experts,
we are planning to install Netweaver 04s sp stack 9 full java edition with Oracle 8i on windows platform.
we have the installation docs of portal but we didn't have any idea about how to configure Portal server with the Backend Oracle database at the time of installation or after ost installation of portal.can anyone provide the documentation about this or guide me how to achieve this.
PLZ share ur views---your help would be highly appreciable.
Regds
Phani.

HI
if you r working in Sap enterprise portal use for connection url
jdbc:sap:sqlserver://ilsql01.tlv.sap.corp:1433;DatabaseName=Northwind
ilsql01.tlv.sap.corp:1433 this is your portal url with port number
Northwind is your database name.
for dirver you need to give
com.sap.portals.jdbc.sqlserver.SQLServerDriver
in case if you r working on other than sap say windows along with oracle try to use
Connection URL as jdbc:oracle:<drivertype>:@<database>
Driver name as oracle.jdbc.driver.OracleDriver
ex jdbc:oracle:thick:@localhost:3036:mydb
Oracle implements two types of JDBC drivers:
Thick JDBC drivers built on top of the C-based Net8 client, as well as a Thin (Pure Java) JDBC driver to support downloadable applets. Oracle JDBC drivers are used to create JDBC applications to communicate with Oracle databases.
Oracle extensions to JDBC include the following features:
Data access and manipulation
LOB access and manipulation
Oracle object type mapping
Object reference access and manipulation
Array access and manipulation
Application performance enhancement

How can i convert data from DBF to oracle database 10g?

Sir,
How can i convert data from DBF to oracle database 10g?

I assume you at least know how to dump the contents of foxpro dbf file into CSV format.
Regarding SQL*Loader, hope this demo makes it a bit clear to you...
http://www.princeton.edu/~storacle/sqlloader_demo.shtml
I agree that it is an old web page (references Oracle 8.0.5) but basics remain the same.
If it is still unclear to you after referring above link, then get an Oracle consultant.

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
import java.util.Date;
import java.io.*;
import java.sql.*;
import oracle.sql.*;
import oracle.jdbc.driver.*;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
public class ArrayDemo
public static void passArray() throws SQLException
Connection conn = getConnection();
ArrayDemo a = new ArrayDemo();
Person pn1 = new Person();
pn1.person_id = 1;
pn1.person_name = "SunilKumar";
Person pn2 = new Person();
pn2.person_id = 2;
pn2.person_name = "Superb";
Person pn3 = new Person();
pn3.person_id = 31;
pn3.person_name = "Outstanding";
Person[] P_arr = {pn1, pn2, pn3};
Person[] P_arr_out = new Person[3];
ArrayDescriptor descriptor =
ArrayDescriptor.createDescriptor( "PERSON_TAB", conn );
ARRAY array_to_pass =
new ARRAY( descriptor, conn, P_arr);
OracleCallableStatement ps =
(OracleCallableStatement )conn.prepareCall
( "begin give_me_an_array(?,?); end;" );
ps.setARRAY( 1, array_to_pass );
     ps.registerOutParameter( 2, OracleTypes.ARRAY,"PERSON_TAB" );
     ps.execute();
     oracle.sql.ARRAY returnArray = (oracle.sql.ARRAY)ps.getArray(2);
Object[] personDetails = (Object[]) returnArray.getArray();
Person person_record = new Person();
for (int i = 0; i < personDetails.length; i++) {
          person_record = (Person)personDetails;
          System.out.println( "row " + i + " = '" + person_record.person_name +"'" );
                    public static void main (String args[]){
     try
                         ArrayDemo tfc = new ArrayDemo();
                         tfc.passArray();
     catch(Exception e) {
                    e.printStackTrace();
          public static Connection getConnection() {
     try
                         Class.forName ("oracle.jdbc.OracleDriver");
                         return DriverManager.getConnection("jdbc:oracle:thin:@<<HostNanem>>:1523:VIS",
                         "username", "password");
     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]
Thanks

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 oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)

                    at oracle.sql.ARRAY.<init>(ARRAY.java:152)
                    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.
Regards,
Shamik

How can i save the data from the Oracle database to my local directory

How can i save the data from the Oracle database to my local directory instead Of saving the data file to the Directory created on the Oracle Server ?
I require to design the Procedure which will pull the data from various tables and needs to store the data in the Client's local directory.

Since SQL*PLUS runs on the client, you can use SQL*PLUS to spool data to your local drive.
You could also use the database to write a a specified drive where all users have access to (mapped network drive, e.g.). I wouldn't recommend doing it that way, but it is sometimes useful when the files are created in some nightly batch run.

the form didn't bring any data but the problem is the field in the form at the run time changed to read only. So how to make it inputText and clear the data inside it at the run time
best regards

How to charge for the first time?

I bought myself a new iPhone and this was from the store, not from someone else, so how should I charge it for the first time? Should I wait when iPhone loads out till blank screen and the charge it to 100%?
How do you charge your iPhone by the way, sometimes I think that I should not let it load out till the blank screen, because when I put it on charge it sometimes took at least three times to begin charging - instead it loaded me the apple logo, waited for a second and then it loaded itself out, then I needed to push the sleep/wake button to turn it on and again it only showed me the apple logo for a second and loaded the iPhone out.
Do you start to charge your iPhone when it gives you the alert that 20% or 10% are remaining?

The new batteries don't need as much care as the old generations. Their lifetime is supposed to be mostly independent of how often and at what charge levels you discharge them. So feel free to charge as you wish.
If it starts showing inaccurate battery levels, calibrate it by doing a full discharge/recharge cycle.
