Hello there,

I am using the driver from mysql.com and it gives me the java.sql.SQLException: NOo suitable driver. This is the same driver I am using to access teh database with the site, but with the Hibernate Mapping SchemaExport I get that error. What can I do to fix it.

Start by showing:
your exception stacktrace
your hibernate.properties (espeically your jdbc url)
etc.

It's probably a mistype in one of the above (or a missing jdbc driver)

## the Transaction API abstracts application code from the underlying JTA or JDBC transactions

## default is java:comp/UserTransaction

#jta.UserTransaction jta/usertransaction
#jta.UserTransaction javax.transaction.UserTransaction
#jta.UserTransaction UserTransaction


## to use JTATransactionFactory with JCS caching, Hibernate must be able to obtain the JTA TransactionManager

#hibernate.transaction.manager_lookup_class net.sf.hibernate.transaction.JBossTransactionManagerLookup
#hibernate.transaction.manager_lookup_class net.sf.hibernate.transaction.WeblogicTransactionManagerLookup

## set the maximum JDBC 2 batch size (a nonzero value enables batching)

hibernate.jdbc.batch_size 0


## enable use of JDBC 2 scrollable ResultSets (specifying a Dialect will cause Hibernate to use a sensible default)

#hibernate.jdbc.use_scrollable_resultset true


## use streams when writing binary types to / from JDBC

hibernate.jdbc.use_streams_for_binary true


## specify a default schema for unqualified tablenames

#hibernate.default_schema test


## use a custom stylesheet for XML generation (if not specified, hibernate-default.xslt will be used)

#hibernate.xml.output_stylesheet C:/Hibernate/net/sf/hibernate/hibernate-default.xslt


## enable outerjoin fetching (specifying a Dialect will cause Hibernate to use sensible default)

#hibernate.use_outer_join false



############
### JNDI ###
############

## specify a JNDI name for the SessionFactory

#hibernate.session_factory_name hibernate/session_factory


## Hibernate uses JNDI to bind a name to a SessionFactory and to look up the JTA UserTransaction;
## if hibernate.jndi.* are not specified, Hibernate will use the default InitialContext() which
## is the best approach in an application server

#file system
#hibernate.jndi.class com.sun.jndi.fscontext.RefFSContextFactory
#hibernate.jndi.url file:/

#WebSphere
#hibernate.jndi.class com.ibm.websphere.naming.WsnInitialContextFactory
#hibernate.jndi.url iiop://localhost:900/

*****************************
My url for database is jdbc:mysql://localhost

Looks correct - so my guess is that the mysql.jar (or whatever name the .jar is) are not on the classpath.

I do have it in the class path. this is the .bat file

@echo off

I wonder your MySql version.

I suggest that you go to http://www.mysql.com/ to get suitable jdbc driver for your current MySql server.

I made it easier to see the whole thing by providing a link to the zip folder

http://www.craanhosting.com/hibernate/hibernate-2.0.zip

Anoter problem, your connection url is correct?

Could Hibernate locate at a default database if you do not add the preferred db name?

You have declared two drivers in your properties file:

hibernate.connection.driver_class org.gjt.mm.mysql.Driver
hibernate.connection.driver_class com.mysql.jdbc.Driver

that fixed it

That was weird

:-)
in your demo.bat, you wrote

set JDBC_DRIVER=C:\Progra~1\SQLLIB\java\db2java.zip
~~~~~~~~ to connect to mysql?

Thank you so much guys

Why does your MySQL Jdbc database assignment have no database named? Your format 'jdbc:mysql://localhost ' doesn't match the usual one: 'jdbc:mysql://HOST/DBNAME'. Where are you specifying the database name? You're not even specifying the default schema:
#hibernate.default_schema test

Regards,
David

P.S. I'm going to look at your download but I'm on a momen so downloading everything you put up there is taking a while.

Two points:

in demo.bat

set JDBC_DRIVER=lib\mm.mysql-2.0.6.jar
java -cp src;build;%JDBC_DRIVER%;lib\commons-logging.jar;lib\commons-collections.jar;lib\commons-beanutils.jar;lib\commons-lang.jar;lib\cglib.jar;lib\bcel.jar;lib\odmg.jar;lib\jdom.jar;lib\xml-apis.jar;lib\xerces.jar;lib\xalan.jar;hibernate.jar net.sf.hibernate.eg.NetworkDemo
