|
|||
|
||||
Helma Object Publisher is a web application server.
|
||||
|
||||
With Helma Object Publisher (sometimes simply refered to as Helma or Hop) you
|
||||
can define Objects and map them to a relational database table. These so-called
|
||||
HopObjects can be created, modified and deleted using a comfortable
|
||||
object/container model. Hence, no manual fiddling around with database code is
|
||||
necessary.

|
||||
|

HopObjects are extended JavaScript objects which can be scripted using
|
||||
server-side JavaScript. Beyond the common JavaScript features, Helma provides
|
||||
special "skin" and template functionalities which facilitate the rendering of
|
||||
objects via a web interface.

|
||||
|
||||
Thanks to Helma's relational database mapping technology, HopObjects create a
|
||||
hierarchical structure, the Url space of a Helma site. The parts between slashes
|
||||
in a Helma Url represent HopObjects (similar to the document tree in static
|
||||
sites). The Helma Url space can be thought of as an analogy to the Document
|
||||
Object Model (Dom) in client-side JavaScript.

===================
|

|

Windows:
|

1) On Windows Helma won't run with Microsoft's version of Java (jview).
|

You can get a compatible Java runtime from Sun or IBM:

2) In the Windows start script I've hardcoded c:\java\lib\classes.zip

in the CLASSPATH argument. Not good.

Macintosh:

1) If you are using the Mac version you should own a G3 CPU and/or
|
||||
have MRJ 2.2 (http://www.apple.com/java) installed. Other platforms
|
||||
have less frustration potential. The Mac OS version currently is not
|

up-to-date (version 0.1).

|

|

Linux:
|

The recomended virtual machine for running Helma on Linux is Blackdown's
|
||||
port of JDK 1.2.2 RC4 (http://www.blackdown.org/java-linux/mirrors.html).
|
||||
JDK 1.1.7v3 will work, but much slower and show a lot of CPU activity
|
||||
even when the Helma is idle. IBM's version of JDK 1.1.8 also works well,
|
||||
but this JVM has some problems of its own with thread handling.

INSTALLING AND RUNNING HELMA
|
||||
============================
|
||||
|
||||
Simply unzip the contents of the archive file into any place on your hard disk.
|
||||
Start Helma by opening the file hop.bat or hop.sh, respectively.

|
||||
|

If you manage to get it running you should be able to connect your browser to
|

http://127.0.0.1:8080/ (port 8080, that is).

This version is set up to use its own embedded Web server and a very basic

|
||||
|
||||
On the other hand, the embedded Web server and object db are meant for
|
||||
development work and not ready for prime time deployment. For that you'd
|
||||
probably use an external relational database, the Berkeley DB package and a full
|
||||
featured Web server like Apache.
