- public class ConnectionApplet
- extends Applet
This applet simply connects to a database. It is useful for
diagnosing problems with database connections from applets, such as
Java security manager restrictions and incorrect connection URLs or
CLASSPATHs.
The ConnectionApplet.java source file contains very little
executable code, but is is heavily commented; if you have problems
running this applet, be sure to read the comments in this source
file. Also, try running the
SocketApplet example to test that you open a socket on the
database server host machine.
To set up this example:
- Set up your development shell as described in Package examples.jdbc.mssqlserver4.
- In the ConnectionApplet.java
file, change the database URL, login, and password connection
parameters to correspond to your Microsoft SQL Server
configuration. If you need more help, check
the section on connecting to a database in the Developers Guide, Using
WebLogic jDriver for Microsoft SQL Server.
- Compile this example by executing the following command in your development shell:
$ javac -d c:/weblogic/mssqlserver4/classes ConnectionApplet.java
- Run this example by executing the following command in your development shell:
$ appletviewer ConnectionApplet.html
