Source files:

TreeFramework.html

(this html page),

TreeDef.xml

(static XML layout),

TreeFramework.jsp

(server script generates and processes XML data),

../Database.*

(source SQL database, table TreeData),

../Framework/TreeGridFramework.jsp

(TreeGrid JSP framework support script, included into TreeFramework.jsp script)

You have to copy file hsqldb.jar to your JRE shared lib directory and restart your http server

The JSP service program must have write access to all files database.*

The

hsqldb.jar

is JDBC driver for

HSQLDB database

and is located in TreeGrid distribution in /Server/Jsp/ directory. The shared lib directory is usually jre_install_path/lib/ext and also e.g. in Tomcat is usually tomcat_install_path/shared/lib.
You can use any other SQL database instead of HSQLDB (e.g.

Oracle

,

MS SQL server

,

MySQL

,...), just assign different connection to java.sql.Connection Conn in the TreeFramework.jsp. You can run the ../MySqlUTF8.sql script to create the "TreeGridTest" sample database on your SQL server.
