This is the README file for version 1.2 of Helma Object Publisher.
===========
ABOUT HELMA
===========
============================
ABOUT HELMA OBJECT PUBLISHER
============================
Helma is a scriptable platform for creating dynamic, database backed
web sites.
Helma Object Publisher is a web application server.
Helma provides an easy way to map relational database tables to objects.
These objects are wrapped with a layer of scripts and skins that allow
them to be presented and manipulated over the web. The clue here is that
both functions and skins work in an object oriented manner and force
a clear separation between content, functionality and presentation.
Actions are special functions that are callable over the web. Macros are
special functions that expose functionality to the presentation layer.
Skins are pieces of layout that do not contain any application logic,
only macro tags as placeholders for parts that are dynamically provided
by the application.
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.
In short, Helma provides a one stop framework to create web applications
with less code and in shorter time than most of the other software out
there.
===================
SYSTEM REQUIREMENTS
===================
You need a Java virtual machine 1.3 or higher to run Helma.
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:
http://java.sun.com/j2se/1.3/jre/download-windows.html
http://www.ibm.com/java/jdk/download/ 2) In the Windows start script
I've hardcoded c:\java\lib\classes.zip in the CLASSPATH argument. Not
good.
For Windows, Linux and Solaris you can get a Java runtime or development
kit from http://java.sun.com/j2se/downloads.html.
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).
If you are on Mac OS X, you already have a Java runtime that will work
well with Helma.
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.
Unfortunately, there is no Java 2 interpreter for Mac OS Classic, so
you can't use Helma on Mac OS 9.
============================
INSTALLING AND RUNNING HELMA
============================
Simply unzip or untar the contents of the archive file into any place
on your hard disk. Start Helma by invoking hop.bat or hop.sh from the
command line, depending on whether you are on Windows or
Linux/Unix/MacOSX. If the java command is not found, try setting the
JAVA_HOME variable in the start script to the location of your Java
installation.
You may also want to have a look at the start script for other settings.
You can adjust server wide settings in the server.properties file. For
example, you should set the smtp property to the name of the SMTP server
that Helma should use to send Email. Applications can be started or
stopped by editing the apps.properties file through the web interface
using the Management application that is part of 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://localhost:8080/ or http://127.0.0.1:8080/
(port 8080 on the local machine, that is).
browser to http://127.0.0.1:8080/ (port 8080, that is).
Helma comes with a version of Jetty, a lightweight yet industrial strenth
web server developed by Mortbay Consulting. See http://jetty.mortbay.com/
for more information. While Jetty works well for deploying real web sites,
you may want to run Helma behind an existing web server. This is most
easily done by running Helma with the AJPv13 listener which allows you to
plug Helma into any web server using the Apache mod_jk module. See
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/index.html for more
information on mod_jk and AJPv13.
This version is set up to use its own embedded Web server and a very
basic embedded object database. For this reason it is able to run
virtually without installation on any platform with a Java 1.1 virtual
machine.
Finally, Helma can be plugged into Servlet containers using Servlet
classes that communicate with Helma either directly or via Java RMI.
(Be warned that these options may be harder to set up and maintain though,
since most of the recent development efforts have been geared towards the
mod_jk/AJPv13 setup.)
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.

DOCUMENTATION AND FURTHER INFORMATION
=====================================
Currently, documentation-in-progress is available online at
http://helma.org/. We know that it sucks and hope to do some substantial
improvments within the coming weeks and months.
Currently, a documentation-in-progress is available online only.
Please refer to http://helma.org/docs/.
Your input is highly welcome. There is a mailing-list to discuss Helma at
http://helma.org/lists/listinfo/hop. Don't hesitate to voice any questions,
proposals, complaints, praise you may have on the list. We know we have
a lot to do and to learn, and we're open to suggestions.
