public class records

extends java.lang.Object

This example constructs a dbKona TableDataSet for inserting, updating, and deleting records from an Oracle database. To run this example, you must have the Oracle DEMO database running. The connection to the database is made with WebLogic jDriver for Oracle. This example is run from the command line and results are displayed to standard out.

For other examples of how to display query results, check the server-side Java examples that use htmlKona and dbKona in the examples/servlets directories.

If you don't have the Oracle DEMO database, you can use the file utils/ddl/demo.ddl to set it up.

The following section describes how to build and run the examples:

1. Build the example
2. Configure the server
3. Run the example

Build the example

1. Set up your development shell as described in Setting up your environment for building and running the examples.

2. Set your PATH to include the path to the WebLogic jDriver for Oracle DLLs. For example:

   set PATH=%PATH%;C:\bea\weblogic700\server\bin\oci817_8

3. Set your CLASSPATH to include the path the BEA_HOME folder where the license.bea file resides. For example:

   set CLASSPATH=%CLASSPATH%;C:\bea

4. Open records.java for editing and find the following code block:

          Properties props = new Properties();
          props.put("user",     "scott");
          props.put("password", "tiger");
          props.put("server",   "DEMO");
    

   You may need to replace these values to fit your configuration.

5. Compile the example by executing an ant build script or a command.
   • An ant build script is available in the samples\examples\dbkona directory. Enter the following command to execute the build script:

     prompt> ant, or

   • Enter the following command to compile the example:

     prompt> javac -d %CLIENT_CLASSES% records.java

Run the example

1. Run this example by executing the following command in your development shell:

   prompt> ant run_records

Method Detail

main

public static void main(java.lang.String[] argv)

First the JDBC connection is set up and created. Using the JDBC connection object, a TableDataSet is constructed without using SQL -- by supplying the Connection object and the name of the Oracle table. In this example, there is code for inserting, updating, and deleting records with SQL that is automatically generated.

Creating a TableDataSet with a KeyDef is also illustrated in this sample code, which is required for updates and deletes to the DBMS data. You can save at either the record level or the table level with dbKona.
