JDBC beginner too

Hi,
I am trying to learn how the JDBC intergrates with JSP. I have imported the following:
<%@ page import="java.sql.*" %>
<%@ page import="java.math.*" %>
<%@ page import="oracle.jdbc.*" %>
<%@ page import="oracle.sqlnet.*" %>
<%@ page import="oracle.gss.*" %>
and I have places the oci73jdbc.dll in the PATH. I am getting the following error: java.lang.UnsatisfiedLinkError: no oci73jdbc in java.library.path What do I need to do? I am not familar with that error or how to solve it. Thank you.

You must set the environment variable LD_LIBRARY_PATH to $ORACLE_HOME/lib -- that should do it.

Beginner Has Problem With Loading JDBC Driver Using MySQL

Hi, I am having problem with loading JDBC driver, and need your diagnotic help.
1. I have installed MySQL (C:\mysql), created a databse (soup), and created a littel table (VIDEOS). I am able to see the table in the console:
sql> select * from videos
2. I have downloaded the latest version of Connector/J (mysql-connector-java-3.1.0-alpha.zip), and unzip the zip file into my C:\ directory.
3. I copied the mysql-connector-java-3.1.0-alpha-bin.jar to the C:\j2sdk1.4.1_02\jre\lib\ext folder and it is in my CLASSPATH
4. MySQL server is running
C:\> C:\mysql\bin\mysqld-nt --standalone
5. open another DOS window and use the database
mysql>USE SOUP
6. succesfully compiled a Java program (javac Test.java):
import java.sql.* ;
public class Test
public static void main( String[] args )
try
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
try
Connection con = DriverManager.getConnection( "jdbc:mysql://localhost:3306/soup" );
try
Statement statement = con.createStatement();
ResultSet rs = statement.executeQuery("SELECT TITLE FROM VIDEOS");
while ( rs.next() )
System.out.println( rs.getString( "TITLE" ) );
rs.close();
statement.close();
catch ( SQLException e )
System.out.println( "JDBC error: " + e );
finally
con.close();
catch( SQLException e )
System.out.println( "could not get JDBC connection: " + e );
catch( Exception e )
System.out.println( "could not load JDBC driver: " + e );
7. when I run the Java program (java Test), I got
the message:
could not load JDBC driver: java.lang.ClassNotFoundException: org.gjt.mm.mysql.Driver
What am I missing?

Hi,
I missed to specify test in my last post.
Try running your program by explicitly setting the classspath when
running your program . java -classpath c:\mysql-connector-java-3.1.0-alpha-bin.jar test
Make sure your jar file contains org.gjt.mm.mysql.Driver class

Beginner's Question on Inserting a BLOB with JDBC

What is the easiest way to accept a file from a user and insert it into a BLOB field in a database?
If it makes a difference - I'm using DB2 and DB2's JDBC driver
But I would like to know the simpliest solution (maybe even using the JDBC-ODBC bridge)
-Michael

Hi Michael,
with DB2's JDBC driver it is pretty easy:
You use a prepared statement and the method setBinaryStream or setBytes:
PreparedStatement pstmt = con.prepareStatement("UPDATE myTable SET blobColumn = ? WHERE ID = ?");
FileInputStream in = new FileInputStream(...) ;
pstmt.setBinaryStream(1, in, in.available()) ;
pstmt.setInt(2, id) ;
pstmt.execute() ; Or you read the file first into an array of bytes and put it in the database with pstmt.setBytes(...)

Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

I have got them or newer verion.

Ant 1.5
===================
i should have this perl 5.8.0-1 but when i install it directly from the net, it only has perl 5.6.2.-1 and it's doc 5.8.0-1.
i think i have installed the ant correctly but is there any way that i could test it??
what is the different between
String url = "jdbc:postgresql:myDB"; and
jdbc:postgresql:localhost:5432/myDB
Just check the port number that you're actually
using.
how and where can i find it out??? or u mean the usually postgreSQL's port number??
Also make sure that you have installed cygipc and that
it is running. Take a look through
<cygwin>\usr\doc\Cygwin\postgresql-7.3.2.READMEi have installed cygipc - any ways i could test it?
thanks in advance

XI: RFC to JDBC scenario - handle JDBC Adapters Errors

In scenario could happened to ERP side try to insert an already saved record in receiver side SQL Server. when this happens XI returns a message structure like :
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

But i need to read this error message and map to RFC response structure, how can i do that?

Hi Karoline,
     Well, i create a BPM process and put a Block Step with Exception Lane, so in normal lane a create a Send Step with the JDBC message, and when an error occurs the process goes to the Exception Lane and there a create a Transform Step with other mapping for de response message for the beginner step, something like:
1º) Receive Step: Sender system with open bridge;
2º) Transform Step: mapping de Sender message request to JDBC request message;
3º) Block Step:
     3.1) Normal Lane: Send Step for JDBC Receiver System;
     3.2) Exception Lane: Transform Step with a message mapping with a constant error message;
4º) Send Step: Sender System with closes bridge;
I couldn´t pick up the correct error message from jdbc driver, but in this model my process doesn´t stop with a JDBC error.
If you have an eMail address i can send to you my model.

"Name jdbc is not bound in this Context" when conncetiong from different pa

Hi,
I'm just a beginner at this so I'll have to explain everything in details as i have no idea what could be wrong.
I have a working connection to mydatabase using the following method in a CommonMethods.java file in WEB-INF; this file belongs to the "package mrkt.app;" package.
    public Connection getDataBaseConnection() {
        Connection conn = null ;
        try {
            Context ctx = new InitialContext();
            DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/myproject");
            conn = ds.getConnection();
        } catch (Exception ex) {
            ex.printStackTrace();
        return conn ;
    }     I needed to create a new class in package "package mrkt.app.cat.shop;", in this new java file i need access to the database so i just copied and pasted the above code in the new java file, compiled it, put it in the "WEB-INF/classes/mrkt/app/cat/shop" folder, restarted tomcat to reload classes. The class is loaded successfully, but i always get the following error when calling the method(getShopsCount) using the connection function (getDatabaseConnection)

I have the same problem!
I created a couple of virtualhost on the same webapp like described here
http://www.onjava.com/pub/a/onjava/2003/06/25/tomcat_tips.html
the application works without problems if I point my browser to
http://ip_address/webapp
but, if I open http://www.myvirtualhost.com/ I get a
javax.servlet.ServletException: javax.naming.NameNotFoundException: Name jdbc is not bound in this Context
I even defined the same datasource I use for the ip based browsing in the virtualhost datasources (through admin, without restarting tomcat) but I get the same exception... any suggestion?
thanks

Post the part of your code that loads the driver and connects. My guess is you are using a variable for the name of the driver and the variable has not been set to anything(intially set to null).

JDBC - Sybase Connectivity Issue

I'm a Java beginner.When using the java JDBC i'm experiencing the following issues
Connection string used - jdbc:sybase:Tds:<Serverip>:<ServerPort>
Driver File - com.sybase.Jdbc2.Jdbc.SybDriver
Initially when i tried using these values i'm able to establish the database connection.But recently i changed the machine name.I'm using the same machine for both Database and Java.After the machine name changes i'm getting the following error
SQLException:Jz006:caught IOException:java.net.connect Exception.
Please help me...

Just rename back the host. Do it work?
See [http://tmaj.pathology.jhmi.edu/doc/manual/FAQs.html#DATABASE_TROUBLESHOOTING]
I found somewhere that
Note: The following exception occurs when you click Test Connection to connect a Sybase data source from the administrative console.
Test connection failed for data source isagent on server server1 at node
svtaix24Node01 with the following exception: java.lang.Exception:
java.sql.SQLException: JZ006: Caught IOException: java.net.ConnectException: A
remote host refused an attempted connect operation.DSRA0010E: SQL State = JZ006,
Error Code = 0
This exception occurs when the Sybase data source port number is not matched to the port configured in Sybase server.
The default port number is 5000.
Check the port number of your Sybase server in the interfaces file under /<sybase install directory>.

JDBC or RandomAccessFile?

I'm thinking of developing a pure Java application/applet that gets line inputs from text files and stores them in either a random access file or a database, whichever is workable, for later retrieval. I was told I may need SQL so I am thinking of JDBC, which may result in an applet/application that is not pure Java. On the other hand, I am also thinking of using random access files to create a pure Java applet/application. Any advise?

I don't have an SQL database. I am just an instructor
trying to develop a Java solution to solve the problem
of administering, checking, and grading of manual
classroom examinations.
How about the java.sql package? Can it help me?Nothing you have said indicates that you need a database.
If you are beginner in java and especially if you are beginner in programming then I would suggest that you absolutely not use a database. Even if that is the best solution. The complexity would be overwhelming.
If however, you are not a beginner and you want to learn some database skills then there are free databases. You should start with seeing if you have MS Access. That is the best choice. If not then MySQL is probably workable. MySQL is probably harder than MS Access, because it requires more work to get it going. Which could be an advantage if you want the technical challenge but irritating otherwise. There are more obscure free ones but I wouldn't suggest them unless you really want a challenge.
