Mysql jdbc drivers with tomcat?

I am having trouble getting mySQL drivers to work on Tomcat. I have used the driver before with iPlanet Web Server, but I can't seem to get it to work with Tomcat. I am getting this error:
org.apache.jasper.JasperException: In <driver>, invalid driver class name: "org.gjt.mm.mysql.Driver"
The jar for the driver is in my WEB-INF/lib directory of my webapp. Seems like it isn't picking up the jar in the classpath. It was my understanding that jars in this dir were loaded automatically. Is there some way to log the classpath loaded in Tomcat?

run this in one of your jsps and see whats in your classpath.
System.getProperty("java.class.path",".");
I've never a had a problem with it before, but I'm using
mysql-connector-java-2.0.14

Oracle JDBC Drivers with Tomcat

I try to connect to Oracle DB with the JDBC Drivers throught Tomcat JNDI access.
I've tried with the oracle.jdbc.driver.OracleDriver and I have an UnsupportedOperationException when calling the getConnection() method on ma dataSource ref.
So I've tried with the oracle.jdbc.pool.OracleConnectionPoolDataSource and I have an java.sql.SQLException:
Cannot create JDBC driver of class
'oracle.jdbc.pool.OracleConnectionPoolDataSource' for connect URL
'jdbc:oracle:thin:@(description=(address=(host=meditws322)(protocol=tcp)(port=1521)
)(connect_data=(sid=HABILLE)))'
Please help I'm about to break down

Thanks for your reply. I use Oracle JDBC driver. The XSQLConfig.xml was changed to have the following setting:
<connection-manager>
<factory>oracle.xml.xsql.XSQLOracleDatasourceConnectionManager</factory>
</connection-manager>
I'm using Tomcat 4.1.x and Apache Commons DBCP Datasources with org.apache.commons.dbcp.BasicDataSourceFactory. The configuration file does set driverClassName to oracle.jdbc.driver.OracleDriver. All other queries embedded in .xsql files work great, I only have issues with queries containing CURSOR() statements. If I switch back to built-in database connectivity, by changing XSQLConfig.xml and connection parameters in .xsql files everything is working again. When I attempt to use DataSources, I get things like this "oracle.jdbc.driver.OracleResultSetImpl@15780d9" instead of nested XML. The non-nested portion of XML looks fine also, so it is retrieving the data from the database properly. Please let me know if I can provide any additional information that could help in resolving this. Thanks in advance!

Mysql jdbc drivers not found in weblogic server

I want to create a connection pool in weblogic server,
and use mysqldatabase.
My drivers is "org.gjt.mm.mysql.Driver"
I put the jar in "D:\bea\weblogic700\server\lib" ,but when i apply ,there is
an error blow:
Error creating connection pool
     at weblogic.management.internal.ConfigurationMBeanImpl.updateConfigMBeans(ConfigurationMBeanImpl.java:635)
     at weblogic.management.internal.ConfigurationMBeanImpl.invoke(ConfigurationMBeanImpl.java:419)

Can anybody tell me why,thanks!

Weblogic has been designed for nannies...
I've developed a application which uses internally my own jdbc-driver.
After months of really hard work on tomcat (the application works fine) I've tried migrate it to weblogic.
But ...
In weblogic seems mandatory to put the jdbc drivers out of the war!!!. Brilliant!!!
If I move the driver out, I need move the 50% of the application out, also!
If I move part of the application out, nothing works, because... �are the class loaders distinct?. And I'll need to do a lot of extra work because one day one weblogic architect had a great great inspiration.
In the future I'll suggest to my customers to run and not stop when they listen the WEBLOGIC word.

Pablo

XSQLServlet and MM.MySQL JDBC drivers?

Anyone have this configuration working? I am receiving a ClassCastException:
java.lang.ClassCastException: org.gjt.mm.mysql.Connection
Not sure where to begin trying to fix this one. This is with the MM.MySQL 1.2c release version.

Using Oracle8 JDBC Drivers with WebLogic 5.1

We are currently using the BEA WebLogic 5.1 application server and Oracle 8.0.4. We are using the JDBC OCI driver that came out-of-the-box with the WebLogic software. However, we would like to use the driver developed by Oracle, instead.
Does the Oracle8 JDBC driver (both type 2 and type 4) interoperate with WebLogic 5.1? If not, what are the problems that prohibit them being used together?
Thanks... Steve Bursch

Summarizing from previous threads on this forum (I have not run this configuration myself):
The main issue is that you will not be able to use Oracle-specific functionality from the Oracle driver.
This includes all types in oracle.sql, or any APIs on oracle.jdbc.driver.OracleXxxx classes, or JPublisher-generated wrappers for SQL Object Types, collections, or REFs.
Also, since Oracle does not support side-channel result sets, but requires explicit REF CURSOR out parameters from stored procedures/functions, you will not be able to return REF CURSORs to the client, from stored proedures or functions - the getCursor() API that is required is Oracle-specific and not part of JDBC.
As long as you limit yourself strictly to standard JDBC types, and do not require the return of result sets from the server, you should probably be fine.

Bug in Oracle JDBC Drivers with {ts ?}

Oracle fails to set bind variables correctly when using the {ts ?} in an insert. It works ok if you use {d ?}.
Ex:
String st = "INSERT INTO BL(NM,TSTAMP) VALUES (?,{ts ?} )";
System.out.println(dbConn.nativeSQL(st));
java.sql.PreparedStatement stmt = dbConnn.prepareStatement(st);
stmt.setString(1,"test");
stmt.setString(2,"2000-08-18 09:33:45");
int xx = stmt.executeUpdate();
Oracle Reports:
INSERT INTO BL (NM,TSTAMP) VALUES (:1,TO_DATE (?, 'YYYY-MM-DD HH24:MI:SS'))
ConnectionPoolManager failed:java.sql.SQLException: ORA-00911: invalid character
Notice the ? doesn't change to :2.
Whoops.
Also when does Oracle plan to implement {fn }
scalars. There are work arounds but they are not portable. If not soon we will switch our suggested database for our clients.

Configure OC4J with other JDBC Drivers

I want to add ability for OC4J to use mySQL JDBC drivers.
Normally in the J2EE RI you would copy the driver and then use the j2eeadmin tool.
Does anyone have info on getting this to work in OC4J (so I can test EJBs that use that DB).
Note: I did get mySQL working for the JDeveloper9i IDE to get it to work in the IDE I just added a line to C:\jdev9i_902\jdev\binjdev.conf:
AddJavaLibFile C:/mm.mysql-2.0.14/mm.mysql-2.0.14-bin.jar
Thanks

Installing the jdbc drivers

Hello Guys:
I am new to Oracle Application DBA stuff and here is what I have to do now.
I need to install the jdbc drivers in our oracle financials UAT.
Here is what I heard from our Oracle support:
ANSWER
======
The Patch #4159795 status is Deleted, indicates that the patch has been deleted from the patch repository. This usually occurs when the patch has been obsoleted.
However, this bug (BUG:4159795) has been fixed in version 10.2 which means it's solved in the latest releases.
The JDBC drivers are certified to work with the currently supported versions of the Oracle Database. For example, the JDBC Thin drivers in Oracle Database 10g a re certified to work with the 9.2.x, 9.0.1.x, and 8.1.7 Oracle Database releases.
However, they are not certified to work with older, unsupported database releases, such as 8.0.x and 7.x.
http://download.oracle.com/docs/cd/B19306_01/java.102/b14355/getsta.htm#i1008205
Now please tell me what needs to be done. Should i install this on the application server or on the database server. If any one could give me a heads or give me pointers to documents it will be great.
Regards,
Bala

If you are using Oracle 11i, the JDBC drivers are normally upgraded via a patch during a JDK upgrade (1.3.1, or 1.4.2, or 1.5.0). I am pretty sure the note referenced by the analyst has no relevance to Oracle EBS.

How to update oracle jdbc driver to 11.1.0.7.0 JDBC Drivers

HI,
I got a jdbc exception *" java.lang.ArrayIndexOutOfBoundsException "*.
I have known that it is a Oracle JDBC bug and Oracle BUG number is BUG-6396242.
The problem is too many rows per database transaction and it is fixed at version 11.1.0.7 Oracle JDBC Drivers.
Here is the 11.1.0.7 Oracle JDBC Driver Readme.
http://www.oracle.com/technetwork/database/enterprise-edition/111070-readme-083278.html
and the download
http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-111060-084321.html
My question is :
*1.How to update oracle jdbc drivers with those downloads ?*
(ps. I have replaced ojdbc5_g.jar, ojdbc5.jar, ojdbc6_g.jar, ojdbc6_g.jar in $ORACLE/jdbc, but it did'nt work. )
*2.My Oracle version is 11.1.0.6.0, will it be OK if only update the JDBC driver?*
*3.Do I need to update the jdbc driver where my program runs on the client side ?*
Thanks for answers~ :)

Upgrade your database version to 11.1.0.7.
Installation docs are included with all patches and upgrades.

Upgrade 10G to use 10G thin jdbc drivers- OCI

This is wierd...
If I upgrade 10G app server to use the 10G thin JDBC drivers, and set up a data source to use the thin drivers, is there any way that I could score a[b] ORA-01010 invalid OCI operation error when I'm not using an OCI driver?
Anyone else seen this...again, it makes no sense...

You can not and should not use JDK 1.2 with 8i drivers.
If you want to use JDK 1.2 drivers, download the 8.1.6 SDK
from external site.
Please, please, please READ the FAQ at www.oracle.com/java/jdbc

start serving pages GREAT!. I have Mysql working perfectly with PHP on this system. I JUST want to connect with JDBC :)
I've downloaded the MySQL Jdbc Connector/J 3.08 stable installed the .jar file in the $JAVA_HOME/jre/lib/ext as per the README

Nope, it's not a MySQL issue.
I'd recommend NOT putting the JDBC JAR file (or any others, except Sun-sanctioned extensions) in JAVA_HOME/jre/lib/ext.
JDBC JARs belong in TOMCAT_HOME/common/lib or in the WEB-INF/lib directory for your particular app. If you put them in the former, all apps running under Tomcat can have access to them. If you put them in the latter, only your app can see them.
After you've done that, do some reading about JNDI data sources under Tomcat:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html
That way you can get that connection code out of your JSPs and into the web.xml and <Context>, where it belongs. You'll be able to change data sources without rewriting your pages.
Good luck - MOD

Problems with adding Library for a MySQL JDBC driver

Good day,
I am new with the JDeveloper package, so the following could be a user fault.
I found the following:
- I downloaded and installed Oracle JDeveloper 10.1.2.1.10 (latest version).
- I downloaded the latest JDBC drivers for MySQL. ( mysql-connector-java-3.1.10 )
Now, I did the following steps extracted from the link http://www.oracle.com/technology/products/jdev/tips/duff/mysql_and_oc4j3.html it should be quite easy to add the JDBC Drivers to the project.
I did the steps with the following results:
When I Edit the Project properties, follow Profiles -> Development -> Libraries
When I do ' New' , fill in at JS2E the value 'MySQL' and fill in the Class Path (in my case 'C:\javaInstalls\mysql-connector-java-3.1.10\mysql-connector-java-3.1.10-bin.jar').
In that case the [OK] is disabled. I should expect the [OK] button was enabled!
My question: Is this a bug? When not, what am I doing wrong!
Regards,
Mike

I tried it on an other system and had no problems with adding the libraries. It still is a problem on that particular system using the Dutch version of XP. The problem is that the Ok button stays disabled !
Could it bw a version problem with Java? How ever no changes are made to the original configuration, so it should pick up as default the java version of JDeveloper self.

Configuring JDBC connector with my Tomcat server

I realize this may be a dumb question, but I'm having trouble configuring my JDBC connector with my tomcat server. I'm trying to run a simple servlet that will access mysql database. I am almost certain its throwing an exception on the line:
Class.forName("com.mysql.JDBC.Driver");
I have a feeling the tomcat class path isn't finding the connector jar file.
Any help would be greatly appreciated.
Brian

I am almost certain its throwing an exception on the line:
Class.forName("com.mysql.JDBC.Driver");If it's a ClassNotFound exception or the like, then yes. Post the exception and stack trace if you need confirmation of this.
I have a feeling the tomcat class path
isn't finding the connector jar file.That's what I think too. Did you ensure that the MySQL driver JAR file was in the classpath?
It will need to be in common/lib under Tomcat, or WEB-INF/lib under your application.
For a more portable application you should use JNDI to obtain database connection resources, in which case you would want the JAR to be under common/lib.

Problems with jdbc drivers

I'm having problems registering jdbc drivers. I've been trying to register the microsoft Sql Server 2000 jdbc driver so that I can create a connection in my code rather than using entity beans. I've set the CLASSPATH variable to point to the driver's .jar files in the install directory with no success.
I've connected to the database using the driver via the IDE' s Runtime and it tests ok and allows me to create a database schema ok. (I had to copy the driver files to the sun/studio5u1_se/lib/ext dir to enable this) Is there a location I can unpack the drivers .jar files which will make the driver available?
I have also tried setting the CLASSPATH variable to point to the above mentioned directory..but that didn't work either. Can anyone help?

Error Trace in getConnection() : com.pointbase.jdbc.jdbcUniversalDriver

If u type in command line
java -classpath .;<directory containing the driver>
it executes your class file properly
note that <directory containing the driver> is the full path to your driver. I mean, the directory that contains your driver\drivername
eg:
java -classpath .;c:/driver/drivername
don�t forget to put the "dot" before semicolon. If u forget it, java won�t find your class file. your class file must be at the directory you�re executing the command
