JDBC for MySQL + TOMCAT

Anybody knows how to configure the JDBC + TOMCAT?

try to install mysql-connector-java into java home
directory. and specify the path in classpath.
had i answered ur question correctly.No JARs belong in JAVA_HOME.
Tomcat ignores your system CLASSPATH.
This advice is utterly, completely wrong. It's not even wrong.
Put the MySQL JAR in your app's WEB-INF/lib directory, then learn to configure a JNDI data source.

Jdbc for mySql Database

I want to connect to MySql Database. My program Source is :
import java.sql.*;
@SuppressWarnings({"ALL"})
public class test {
public static void main(String args[]) throws ClassNotFoundException, SQLException, IllegalAccessException, InstantiationException {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
Connection con = DriverManager.getConnection ("jdbc:odbc:mysql://127.0.0.1:3306, "root", "edlovema1017");
Statement stmt = con.createStatement();
stmt.executeUpdate("DROP TABLE users");
There is an error when my program is running.
this error :
Exception in thread "main" java.lang.NullPointerException
     at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
     at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
     at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
     at java.lang.reflect.Method.invoke(Method.java:585)
     at com.intellij.rt.execution.application.AppMain.main(AppMain.java:90)

1) How do you compile that?
in
getConnection ("jdbc:odbc:mysql://127.0.0.1:3306, "root", "edlovema1017");closing " is missing for the first parameter
2) why jdbc:odbc:mysql not just jdbc:mysql ?
3) as sabre150 stated, use
Class.forName("com.mysql.jdbc.Driver")instead of
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();4) NEVER leave connection opened - add con.close() at the end
5) Specify the database name, e.g.
getConnection ("jdbc:mysql://127.0.0.1:3306/mydb", "root", "edlovema1017");6) good luck

Has anyone run the connection pooling for mysql & tomcat successfully?

I'm trying to set up connection pooling. I'm following the how-to page at

But when i test the DBTest/test.jsp file, tomcat displays an error =

i have placed all the required .jar files in the tomcat lib.
below is the cofiguration i did to the server.xml file

you have your driver jar in Tomcat\common\lib?
if so, check your classpath, it could be that.

Problem with JDBC driver for mysql

I have downloaded the Connector/J3.0 mysql-connector-java-3.0.7-stable.tar.gz from www.mysql.com/downloads/api-jdbc-stable.html web site and used gunzip and tar to extract the file. I have received the following error message:
tar: directory checksum error
Will this error cause some problem later on?
Which directory should I put the driver into? Can I put it in any directory?
Do I need to set the classpath for the driver? If yes, how can I set it?
What is the connect string? Can you give a sample for me? I am using Solaris 5.8 and mysql is on the same machine.
Thanks a lot,
Lisa

this is an example of a connect string for mysql that i used...
public Connection CreateConnection () throws Exception
     Connection myConn = null;
     String driverName = "org.gjt.mm.mysql.Driver";
     String dbUrl = "jdbc:mysql://www.desres.com/jhazrd?user=jhazrd&password=????";
     Class.forName(driverName);
     myConn = DriverManager.getConnection (dbUrl);
return myConn;

Need JDBC driver string for MYSQL DB Resin server

Please any body provide me the jdbc driver for MYSQL
database for Resin server
Thanks

The driver and URL string are independent of server you deploy them on.
Put that JDBC JAR in your Web app's WEB-INF/lib directory and it'll be in the CLASSPATH.
Set up the pooled data source as appropriate for your server. That's the server-dependent part.

The mysteries of JDBC, JNDI, and Tomcat 5.5.4

Like thousands beforefore, I can't get connection pooling to work in Tomcat. I followed all the steps:
- put jar file for MySQL JDBC driver in TOMCAT_HOME/common/lib
- put the Jakarta Commons libs in the same location
- put resource declaration in META-INF/context.xml, per the Tomcat 5.5 docs like so:
<Context docbase="C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\commutercorps"
    path="\commutercorps" >
    <Resource name="jdbc/commutercorpsds"
        auth="Container"
        type="javax.sql.DataSource"
        maxActive="100"
        maxIdle="30"
        maxWait="10000"
        username="myusername"
        password="mypassword"
        driverClassName="com.mysql.jdbc.Driver"
        url="jdbc:mysql://localhost:3306/commuter_corps_signup"/>
</Context>- added resource ref in web.xml
    <resource-ref>
        <description>DB Connection</description>
        <res-ref-name>jdbc/commutercorpsds</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
    </resource-ref>I also double checked my connection URL and found that it does work fine when do this in my Java code:
Class.forName("com.mysql.jdbc.Driver");
Connection con =
    DriverManager.getConnection
    ("jdbc:mysql://localhost:3306/commuter_corps_signup", "...", "...");When I try to use Tomcat 5.5.4, JNDI like this...
                try
                    InitialContext initialContext = new InitialContext();
                    DataSource dataSource =
                            (DataSource) initialContext.lookup
                            ("java:comp/env/jdbc/commutercorpsds");
                    Connection con = dataSource.getConnection();
                    Statement stmt = con.createStatement();
                    stmt.executeUpdate(SQLMaker.getInsert(request,
                            request.getParameter("table")));
                    con.close();
                    stmt.close();
                } catch (NamingException e)

I wanted to use Hibernate. So i used, extensiontools.What's that?
First create a env var: HIBERNATE_HOME pointing to
the hibernate extracted dir.No need for this.
Modify setenv.bat to correct %CP% for
commons-logging, commons-collection and anything
else: the version string at the end of the jar
changes.Wrong. You shouldn't be doing this.
Then run ddl2hbm, straightforward, fill info in all
tabs and hit generate. Will show some error message,
but still creates xmls.I don't see what any of this has to do with Tomcat deployment.
Then run hbm2java, and hand over each xml file as
parameter. Creates some java files in generated dir.
Modify the toString method to something simpler and
remove the import for apache class.All great, but still has nothing to do with Tomcat deployment.
move them over to webapp classes.You should create a WAR file or a separate context directory for your application under /webapps. If you're doing anything else, it's wrong.
Create JNDI in sever.xml as mentioned.Nope. Shouldn't be editing server.xml. Put that stuff in an application-specific context.xml, which goes in the META-INF of your WAR file.
Create reference in web.xml as mentioned.Good.
Goto conf/catalina/localhost/<webappname>.xmlNo need for this. Don't know what you're doing here.
add the line
<ResourceLink name="jdbc/Oracle"
type="javax.sql.DataSource" global="jdbc/Oracle"/>
replace Oracle with your datasource name.
and i got me workingMight be working, but it's not really correct.

Getting JNDI not found on MySql/Tomcat

Has anyone gotten ADF to work with MySql/Tomcat? I think I finially have the app working in Tomcat but now I'm getting an error with my pool/JNDI lookup. At the tomcat console I get this;
SEVERE: Null component Catalina:type=DataSource,path=/ediweb,host=localhost,class=javax.sql.DataSource,name="jdbc/ediconnDS"
It looks like it can't even create a connection to MySql. My app has a context.xml in the META-INF like this;
<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<ResourceLink global="jdbc/ediconnDS" name="jdbc/ediconnDS" type="javax.sql.DataSource" />
</Context>
And in my server.xml I have this;
<Resource name="jdbc/ediconnDB" auth="Container" type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000" username="root" password="password" driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/freightedi"/>
In my web.xml I have this resource-ref;
<resource-ref>

<res-ref-name>jdbc/ediconnDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
I've tried putting the resource in the context.xml... all kinds of stuff, to no avail.
I tested these connection parameters in Squirrel SQL (java jdbc based SQL tool) and it works?!
Please help :(

Problem loading jdbc driver in Tomcat

Hi,
I have got a connection to MySQL5.0 from TomCat 5.5.13, that was test correctly in development (JSC Upd 1) but I encounter the following deployment error :
com.sun.rave.web.ui.appbase.ApplicationException: org.apache.jasper.JasperException: org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot load JDBC driver class 'com.mysql.jdbc.Driver'
When I verify, I found that if I put the mysql Connector JDBC driver in <tomcat>/common/lib, there is no error.
But when the MySql Connector JDBC driver resides in <tomcat>/shared/lib, the error persists.
What's the difference ? shouldn't it work for both ?
Thanks in advance for any pointers and advise.

hmm... i guess that it's a must to include the lib at /common/lib instead of shared/lib .
Is there a Tomcat resource that I can read up on ?

Persistent Store Problems for MYSQL Enhanced Cluster With OpenMQ 4.4

I am trying to implement an enhanced cluster with failover. I have edited the config files for each broker instance for a persistent store. I have appended the following to each of the config.properties files:
imq.brokerid=myclusterinstanceINSTANCE1 # I substitute INSTANCE2 for INSTANCE1 for broker #2
imq.persist.store=jdbc
imq.persist.jdbc.dbVendor=mysql
imq.persist.jdbc.mysql.property.url=jdbc:mysql://xxx.xxx.xxx.xx:3306/test
imq.persist.jdbc.mysql.user=user1
imq.persist.jdbc.mysql.needpassword=true
imq.persist.jdbc.mysql.password=mypass
imq.cluster.ha=true
imq.cluster.clusterid=mycluster
imq.cluster.brokerlist=xxx.xxx.xxx.x:37676,yyy.yyy.yyy.y:37676
I then create the persistence storage with "imqdbmgr create tbl". When I view the data in the tables it creates, I have one row. Under Store_Version, I have 410. Under LOCK_ID, it has NULL. When I go to start the brokers with imqbrokerd, I get the following error:
ERROR [B3198]: Error initializing cluster manager:

I believe this error is attributed to the NULL value under LOCK_ID. I think that the value under LOCK_ID should be the name of the broker from the config file (even though I specified them in the config files). Any ideas?? THANKS!

Just some pointers -- maybe this will be of use:
If you haven't already read it, please take a look at the [ MySQL setup guide|https://mq.dev.java.net/OpenMQ_MySQLCluster_Setup_Guide.html] .
We recommend using NDB Data-store of MySQL Cluster, though this isn't an absolute requirement. Due to some issues we have found with earlier versions, we recommend using MySQL Cluster, 7.0.9 or better (the current version is 7.0.16, or 7.1.5). Either of these would contain Connector/J.
I'd also recommend using the latest version -- MQ 4.4update2 (just in case you happen to have an older copy). There were many minor improvements in the integration with MySQL from the original 4.4 release, to update 2. This is linked at the MQ download page: [https://mq.dev.java.net/downloads.html]

Help needed for MySQL 5 database DSN less connection with Oracle reports

Hi,
I am using Oracle Develper Suite and java (J2EE) for my application. I am using MySql 5 as database tool. I want to use Oracle reports of Oracle Develper suite. I have created some reports by first creating system DSN for MySql database and then connect Oracle reports to that DSN by "jdbc:odbc" connection string provided in Oracle Report developer wizard. This is working fine.
I want to generate reports without creating system DSN (DSN less) so that i can use my application on any computer without creating DSN for Oracle Reports. I am deploying my application on OC4j as "EAR" file.
Help in this regard will be highly appreciated.
Regards.

Using an 8i client, you will need to configure the tnsnames.ora file with appropriate connection information if you are using local naming. If you are using host naming or something like an Oracle Names server to resolve TNS aliases, you can skip the tnsnames.ora configuration. A default installation of the Oracle client, though, will probably be using local naming.
If the tnsnames.ora file is configured, or you have configured an alternate way of resolving TNS aliases, you should be able to use the connection string
DRIVER={Oracle ODBC Driver};DBQ=<<TNS alias>>;UID=system;PWD=managerIf you wanted to move to the 10g client (the 10g Instant Client could be useful here), there are some streamlined naming methods that could be used instead of configuring the tnsnames.ora file.

I have a problem with JDBC Realm in Tomcat/Oracle/Win XP

I have a problem with JDBC Realm in Tomcat.
I have attached my server.xml file located in the
C:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\server.xml
The Problem is that when I login I get the user name and password prompt but it does not resolve.
When I enter in the tomcat-users.xml password with memory realm uncommented it works fine.
C:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\tomcat-users.xml
Is there a cache or something I need to reset for the JDBC Realm to work?
I have attached my tables and contents as well...
Did I miss something????
Thanks

Goto properties->advanced->environment variables.
Look for 'classpath' under system variable.
Select it and click edit.
put ';' and path of the mysql connector jar at the end
suppose if u have jar file under d:/driver/mysqlconnector.jar
thn put this value in variable value text box
;d:/driver/mysqlconnector.jar
or simply put ur driver jar file in jre/lib/ext folder

Problems using Quick Migrate in SQL Developer 1.5 for MySQL to Oracle 10g

Hi all,
I am trying to use SQL Developer 1.5 migration tools (Quick Migrate) to perform online capture and build source model to migrate from MySQL 5.x to Oracle 10g on Windows platform. I get these errors and the Quick Migrate process fails:
oracle.dbtools.metadata.persistence.PersistableObject.doInsert(PersistableObject.java:238)
I did a search and used the sqldeveloper.cmd script but still fails. Then I created a new database and truncated the repository. I now get the above error plus two new ones listed below:
oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
Error loading nls:OALL8 is in an inconsistent state
Error occurred during capture: Protocol violation
It fails during the capture process for MySQL 5.1 database
when it begins to capture the tables from MySQL.
Does anyone know how to resolve these issues when migrating from MySQL to Oracle 10g using Quick Migrate with SQL Developer 1.5 release?
Regards,
Ben Prusinski

Hi all,
I put the following in my sqldeveloper.cmd file:
SET ORACLE_HOME=%CD%
What is very confusing is that with SQL Developer 1.5, there are several levels and several SQL Developer executables! I am really not sure which of these to use:
I created the SQLDeveloper 1.5 directory called SQLDeveloper1_5 on Windows:
1) cd C:\sqldeveloper1_5\sqldeveloper-5338
there exists a sqldeveloper.exe
2) cd c:\sqldeveloper1_5\sqldeveloper-5338\sqldeveloper\sqldeveloper.exe
3) cd c:\sqldeveloper1_5\sqldeveloper-5338\sqldeveloper\sqldeveloer\bin\sqldeveloper.exe
Which SQLDeveloper 1.5 executable should I be using and where should I place the
sqldeveloper.cmd file?
Also I did try to use a different database and schema for the repository with Quick Migrate but it appears a bug exists in SQL Developer 1.5 version that causes errors with Quick Migrate for MySQL to Oracle? Is this correct?
As an update, I ran the following commands:
cd to
c:\sqldeveloper1_5\sqldeveloper-5338\sqldeveloper\sqldeveloper\bin
sqldeveloper.cmd sqldeveloper.exe
Start sqldeveloper.exe
Perform standard capture for MySQL using the new mig2 schema as the new repository
It starts the capture but fails on the errors below:
Error loading nls:OALL8 is in an inconsistent state
UPDATE
============================
I tried this again and it worked with the exception of one error message listed below:
Here are the steps that I followed:
1. Create a Windows cmd script
Put the following entries in the script:
SET ORACLE_HOME=%CD%
save the command windows script as sqldeveloper.cmd
Copy this script to the base installation directory for SQLDeveloper
Example:
1. cd c:\SQLDeveloper1_5\sqldeveloper-5338\sqldeveloper
2. Start SQLDeveloper with the command script that you created earlier
Example:
Open a Windows shell prompt window and execute the following scripts:
a) sqldeveloper.cmd sqldeveloper.exe
b) sqldeveloper.exe
3) In SQL Developer 1.5
From the Migrate menu,
a) Delete current repository and create a new schema in Oracle target database call it mig2.
b) Then create a new repository in SQL Developer 1.5
c) Right mouse click on the MySQL 5.x database and choose capture
It worked with the exception of one error message:
o.jdbc.driver.OracleDriver
Error while registering Oracle JDBC Diagnosability MBean.
So it looks like something is screwed up with my JDBC drivers and configuration for MySQL. How do I diagnose the JDBC driver issue for MySQL?
Thanks!!!
Ben
