Sample Database Insert VERSION 1

This handler leverages Java Database Connectivity (JDBC) technology to execute SQL queries against a database server. JDBC provides an abstract inferface for querying against different database systems. In order to configure a connection, a JDBC Driver must be made available, typically by including a .jar file somewhere on the classpath. In order to initializing the JDBC connection, a JDBC driver, or adapter class, associated to the connection must be pre-loaded. Once the JDBC adapter class is loaded, a simple connection string, which specifies the location of the server, name of the database to connect to and a list of parameters can be used to initialize a connection.

Practically, this means that a JDBC .jar file specific to the target database server will need to be added to the Kinetic Task web application WEB-INF/lib directory. Additionally, the adapter class and connection string info values will need to be configured specific to the JDBC adapter that is being used to connect. Below are some example configurations for commonly used JDBC adapters.

DB2 Adapter Class: Connection String: jdbc:db2://[SERVER][:port]/[DATABASE]

Microsoft SQL Server Adapter Class: Connection String: jdbc:sqlserver://[SERVER][:port];databaseName=[DATABASE]

Oracle Adapter Class: oracle.jdbc.OracleDriver Connection String: jdbc:oracle:thin:@//[SERVER][:port]/[SERVICENAME]

MySQL Adapter Class: com.mysql.jdbc.Driver Connection String: jdbc:mysql://[SERVER][:port]/[DATABASE]

Once you have JDBC configured, you will also need to configure the handler to execute your specific query. In the node.xml file, insert your query in the node, using curly braces for the parameters that you wish to be dynamic. Below is an example of a query were the username and password will be dynamic values.

INSERT INTO Users (Id,Name,Username,Password) VALUES ({id},{name},{username},{password})

Any value that you used inside of the curly braces will now need to be added as a parameter. The parameter id must be the same as the value in the curly braces. Later, when defining the parameters nodes that is inside the node (the second set of parameter nodes in node.xml) make sure that the type is equal to the Java class that cooresponds to the parameter type in the database (Integer, String, Date, and Timestamp are supported in this sample). If you want to add a type that is not supported in this sample, you just need to add the type to the logic in init.rb (currently found between lines 76-87).

Once all this is configured, the handler will now be able to insert a value for you to your desired database!

Testing the Handler

NOTE: Testing this handler requires the Kinetic Task 3.0 testing harness.

In order to test this handler, the JDBC .jar file must be made available to the java virtual machine. In order to do this, java must be called directly (rather than executing the kinetic task jar file using java -jar kinetic-task.jar ...). See below for a sample execution (which assumes that the current working directory is the root of the handler):

java -classpath [PATH]\kinetic-task.jar;[PATH][JDBCJARFILE].jar com.kineticdata.task.Main -test-handler=.

The simple test case shows the configuration for executing this handler against a Kinetic Matrix instance, which uses an Oracle database. Included in the test directory is a lib/ojdbc6.jar file, which is a JDBC jar file for Oracle (which requires Java 6 or higher). If the test harness is being run from Java 6 and connecting to a Matrix instance, the following command line can be used to execute the test process:

java -classpath [PATH]\kinetic-task.jar;test\lib\ojdbc6.jar com.kineticdata.task.Main -test-handler=.


IdWill replace {id} value in the query supplied in the config
NameWill replace {name} value in the query supplied in the config
UsernameWill replace {username} value in the query supplied in the config
PasswordWill replace {password} value in the query supplied in the config
