I'm developing in Java, using JSP's and Servlets. The theme of the web site will be Java Technologies in general, with a focus on web development using Java.
As a back-end database I will be using HSQLDB. It's a small database writting 100% in Java.
I will now describe how I got HSQLDB working.
I'll asume that you have knowledge of Java and SQL, and a Java Development Kit and a servlet container installed. I'm currently using Sun's JDK 1.4.2 and Apache Jakarta Tomcat 5.0.28. Furthermore I'm using Gentoo Linux, so if you're using Windows a few changes are required (I'll try to note them, as I go along).
Start by downloading the latest realease, from SourceForge. The file to look for is called hsqldb_1_7_3_1.zip (posibly with a higher version number).
Unzip the archive. I have all my java related files below one common directory, /usr/java/ (c:\Java\ on Windows).
You now have a directory called hsqldb containing all files related to the database. I like to rename this directory to include the version number, e.g. hsqldb-188.8.131.52.
You should add hsqldb-184.108.40.206/lib/hsqldb.jar to you class path. Also you should copy it to your $CATALINA_HOME/common/lib and restart tomcat. You are now ready to compile/run Java-programs using hsqldb.
Run the manager: hsqldb-220.127.116.11/demo/runManager.sh (on Windows use runManager.bat). Enter the following:
Type: HSQL Database Engine Standalone
Now create a table and put some data into it (click Execute-button after copying the following to the text field):
CREATE TABLE Bookmarks (title VARCHAR(50), url VARCHAR(255));
INSERT INTO Bookmarks (title, url) VALUES ('Java Technology', 'http://java.sun.com/');
INSERT INTO Bookmarks (title, url) VALUES ('HSQLDB 100% Java Database', 'http://hsqldb.sourceforge.net/');
INSERT INTO Bookmarks (title, url) VALUES ('Apache Jakarta Tomcat', 'http://jakarta.apache.org/tomcat/'
The first four lines are standard SQL. The final line is HSQLDB specific.
You can test that it worked, by executing this:
SELECT * FROM Bookmarks ORDER BY title;
Exit the manager.
You now have four files in /path/to/your/app called demobase.log, demobase.properties and demobase.script (and if you didn't exit the manager, you'll also have a demobase.lck file). These three files describe your database, and can be copied to say a tomcat server.
This is the end of this part. The next part will show you how to write Java programs and servlets using the database.
