MyJavaServer.com : Java Glossary

I have left this tombstone entry for historical interest.

MyJavaServer.com

Defnct, was a free Java WebServer offering Caucho Resin, JSP (Java Server Pages) and HSQLDB. MySQL was available for those who contribute to the project. The big problem was lack of documentation. Here are some of the basics I have figured out, by experiment and by combing the forums.

You put your JSP and servlet code directly in your assigned FTP (File Transfer Protocol) directory using an FTP upload program like FTP Voyager. You don’t use a WEB-INF structure.

People using your MyJavaServer JSP apps will access a URL (Uniform Resource Locator) like this:
http://www.myjavaserver.com/~roedy/helloworld.jsp

People using your MyJavaServer Servlets will access a URL like this:
http://www.myjavaserver.com/servlet/roedy.HelloWorldServlet
You are sharing the Servlet womb with everyone else.

Note that your Servlets must all be in a root package the same as your account name. You must manually compile them with the Util ⇒ Java menu item. JSP ’s are autocompiling.

HyperSonic SQL (Standard Query Language)

MyJavaServer offers Hypersonic SQL. You are best to get your app working locally with it first. The engine runs in four modes.

Type	driver access	Notes
In-Memory	jdbc:hsqldb:.	No persistence. An applet, for example, could have his very own database running in its own JVM (Java Virtual Machine).
Standalone Engine	jdbc:hsqldb:DATASET	Uses files only.
Server Engine	jdbc:hsqldb:hsql://someserver.com:9001	Allows access from applications running on other machines on the net.
WebServer Engine	jdbc:hsqldb:http://someserver.com:80	toy webserver that lets you issue SQL commands from a browser.

The Remaining Mysteries

What mode is the HSQL engine running? I suspect server mode. The forums hint that MyJavaServer runs their engine in either Standalone mode and in Server engine mode, and that it can only be accessed by Servlets, not via JDBC (Java Data Base Connectivity) in Applets. However, even after a day of searching I have not been able to connect to a database or even find definitive documentation on how to do it. It is unclear how you name databases and where you specify the names. Extremely frustrating! It is getting very hard not to look this gift horse in the mouth.
HSQL appears to use one engine per database. Are all users sharing the same database? If so, how do you specify your corner of it? If not, how do you get your own private HSQLDB server started?
Where do you put your database files?
What sort of getConnection URL do you use to access your database?
How you you upload SQL commands to your database?
How you you upload data to your database?
