[jotnarta]

Hi All

Any one know how to configure a mysql datasource in JBoss??? I am using JBoss 5 and mysql 5, I tried everything, and read everything, :argh:, can anyone help me , pleassssssssse... I always get the following error

Exception thrown java.sql.SQLException: Table not found in statement [select * from questions]

following is my mysql-ds.xml file:

<?xml version="1.0" encoding="UTF-8"?>

<datasources>

 <local-tx-datasource>

 <jndi-name>DefaultDS</jndi-name>

 <connection-url>jdbc:mysql://localhost:3306/project</connection-url>

 <driver-class>com.mysql.jdbc.Driver</driver-class>

 <user-name>root</user-name>

 <password>admin</password>

 <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name>

 <metadata>

 <type-mapping>mySQL</type-mapping>

 </metadata>

 </local-tx-datasource>

</datasources>

and following is my client:

<%@page import="java.util.*,javax.naming.*,javax.sql.DataSource,java.sql.*"%>
<%
 DataSource ds = null;
 Connection con = null;
 //Statement st = null;
 InitialContext ic;

 try {
 ic = new InitialContext();
 ds = (DataSource) ic.lookup("java:DefaultDS");
 con = ds.getConnection();
 //out.println( "Connection: " + con. );

 Statement st = con.createStatement();
 //DatabaseMetaData md = con.getMetaData();

 out.println(" Username: " + md.getUserName());

 ResultSet rs = st.executeQuery("select * from questions");
 //ResultSet rs = md.getTables(null, null, "%", null);

 while(rs.next()) {
 out.println("<br> " + rs.getString("ID"));
 System.out.println(rs.getString(3));
 }
 rs.close();
 st.close();

 out.println("DONE");
 } catch (Exception e) {
 out.println("Exception thrown " + e );
 //e.printStackTrace();
 } finally {
 if (con != null) {
 con.close();
 }
 }
%>

Another questions is, do i have to change something in other files?? and where can i find the log for JBoss server???

Are you sure that there exists a table by name "questions"?

and where can i find the log for JBoss server???

Why don't you check the faq's ???
check at $JBOSS_HOME/server//log/ location for the server log.

Thank you buddy, am sure that table questions do exist in my schema.... :(, but why the program don't see it ??????????????

Ok, configure the sql client with the same details as you have in -ds.xml file and see if you can execute the same query through it, you can use squirrel as client.
Another thing which you can try is to have a simple jdbc program and check if the same statement works Or not.
What errors do you see in the server.log?

Wow, deja-vu all over again.

What operating system are you using? On some OSes MySQL is case sensitive.

If you are still havingproblems, do this: run 'mysql' from a command line, logging in with user name and password from the *-ds.xml file, then enter 'use project', and then enter "show tables'. Post the entire interaction, starting with the 'mysql' command line and ending with the response from 'show tables'.
