%>
You start the application from DBLogin.html. This page prompts the user
to enter a JDBC driver, URL, username, and password to log in to a
database. A list of accessible drivers and URLs is provided in the
selection list. You must make sure that these database drivers are added
into the Libraries node in the project.
When you click the Login button, DBLoginInitialization.jsp is invoked.
When this page is processed for the first time, an instance of DBBean
named dBBeanId is created. The input parameters driver, url, username,
and password are passed to the bean properties. The initializeJdbc
method loads the driver and establishes a connection to the database. If
login fails, the connection property is null. In this case, an error
message is displayed. If login succeeds, control is forwarded to
Table.jsp.
Table.jsp shares dBBeanId with DBLoginInitialization.jsp in the same
session, so it can access connection through dBBeanId and obtain tables
in the database using the database metadata. The table names are
displayed in a selection box in a form. When the user selects a table
name and clicks the Browse Table Content button, BrowseTable.jsp is
processed.
BrowseTable.jsp shares dBBeanId with Table.jsp and
DBLoginInitialization.jsp in the same session. It retrieves the table
contents for the selected table from Table.jsp.
