Java and PHP Applications

How do I enable Java Servlet support for my web site?

Java Servlet support is not enabled by default. If you would like to have Java Servlet enabled, please send an e-mail to Service Centre. Remember to include your domain name, user ID and password in the e-mail.

Once the Jave Servlet is enabled, you will find a new directory called "WEB-INF" in your public_html. Inside this directory you will find another directory called "classes", this is where you place all the classes for your Servlets (i.e. all your Servlets should go into the WEB-INF/classes directory).

To execute your Servlets, point your web browser to:
http://www.your-domain.com/servlet/

For more information on Java Servlet, please refer to Sun's Servlet Resources.

How do I enable JSP support for my web site?

Once Java Servlet support is enabled for your web site, JSP support is automatically enabled. To run Java Server Pages, your web pages must have the .jsp extension. JavaBeans should be placed in the WEB-INF/classes directory under your public_html.

To access your JSP files, point your web browser to:
http://www.your-domain.com/your.jsp

For more information on JSP, please refer to Sun's JSP Resources.

Can I have index.jsp loaded up when accessing www.my-domain.com?

Absolutely. Simply name your startup JSP file as index.jsp and remove or rename other index.* files in your public_html directory.

Can I run my Java application on a dedicated port?

No. This option is not available at this time.

Are there any restrictions to my Java applications?

No. We do not limit the number of Servlets or JSPs you can have in your account. They are only limited to the allocated quota (disk space) based on your Web Hosting plan. From time to time, we may audit your Java applications for potential security issues.

 try {
  Class.forName("org.gjt.mm.mysql.Driver").newInstance();
  con = DriverManager.getConnection("jdbc:mysql://localhost/loginname_dbname",
  "username", "password");
 } catch (Exception e) { ..... }
