Jdbc Driver Newinstance

I m using gradle-1.0-milestone-6 and cannot find a way to put ojdbc6.jar onto the CLASSPATH for my groovy code that calls Sql.newInstance. ., oracle.jdbc.

MySQL Forums:: Connector/JDBC and Java:: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver. New Topic. Class.forName com.mysql.jdbc.Driver. newInstance ;.

JDBC for MySQL. JDBC is the Java Database Connectivity API, Class.forName com.mysql.jdbc.Driver. newInstance ; JDBC Drivers in the Labs.

Note; If you have problems connecting to SQL Server using the JDBC driver, see Troubleshooting Connectivity for suggestions on how to correct it.

java.sql.Driver d new com.mysql.jdbc.Driver ;

I alos wondered why do you connect to database with such this way.. it s better let server manage it.

first config the context.xml if you are using tomcat like this.

Resource name _ds auth Container type javax.sql.DataSource

maxActive 128 maxIdle 32 username _admin password qwerty driverClassName com.mysql.jdbc.Driver

url jdbc:mysql://127.0.0.06/dbname /

then simple get a connection from this resource in servlet/etc, like this

try _ds DataSource InitialContext.lookup java:/comp/env/_ds ; catch Exception ex

private javax.sql.DataSource _ds;

protected void doPost HttpServletRequest request, HttpServletResponse response

throws ServletException, IOException

/ String driver com.mysql.jdbc.Driver ;

Class.forName com.mysql.jdbc.Driver. newInstance ;

con DriverManager.getConnection jdbc:mysql://localhost:3306/dbName, root, password ; /

Connection con _ds.getConnection ;

Statement st con.createStatement ;

ResultSet mar st.executeQuery SELECT FROM table ;

Gson gson new GsonBuilder. create ;

response.setContentType application/json ;

response.setCharacterEncoding utf-8 ;

By the way, don t forget to compy the mysql jdbc driver jar file in /lib folder.

Class.forName("com.mysql.jdbc.Driver").newInstance()

What does Class.forname method do. AClass a AClass c.newInstance ; System.out.println JDBC Driver Is a Good Example.

Hi I have a query, What is the difference between Class.forName. newInstance and Class.forName . regards, S.

Package com.quicklyjava; public class Example Object ob exampleClass.newInstance ; catch oracle.jdbc.driver.OracleDriver ;.

java.lang.ClassNotFoundException: oracle.jdbc.OracleDriver when using Sql.newInstance(......., "oracle.jdbc.OracleDriver")

Here is an example of how you can do this for HsqlDB. I didn t have an oracle instance hanging around so couldn t test against oracle but the procedure should be the same.

As a side note, I did try a number of methods more in the spirit of gradle: adding the class to the buildscript classpath, adding the class to the settings object classloader, using groovy grapes to do this, using the groovy root loader, etc etc. None of it worked, so if some gradle guru has a more proper way of doing this I would be interested to know. If none exists, perhaps it would be worth adding something like the groovy GrabConfig systemClassLoader true syntax to gradle.

This isn t exactly pretty, but the best I could come up with and it works:

def driverClass org.hsqldb.jdbcDriver

String jdbcUrl jdbc:hsqldb:hsql://localhost/myalias;mem:test

def gcl new GroovyClassLoader this.class.classLoader

configurations.hsql.each file -

println Adding file to classpath: file

java.sql.Driver driver gcl.loadClass driverClass. newInstance as java.sql.Driver

def conn driver.connect jdbcUrl, user: sa, password: as Properties

def sql new groovy.sql.Sql conn

sql.eachRow select from test row -

Hope that helps. Let me know if it solves your problem.

If you have not already done so, please review the portion of Section 6.1, Connecting to MySQL Using the JDBC DriverManager Interface above before working.
