Update to xang.war for Tomcat
The version of Xang in the xang.war in my previous message is a not-yet-checked-in version.
It has a new mode that is a workaround to the inability of servlet engines to provide 'extra path info' to servlets that handle file extensions (like *.xap).
In the xang.cfg you can specify one .xap file as the 'app' file. This will let you use a URL that doesn't have a .xap extension in it & you can do sub-url addressing.
For example:
http://localhost:8080/xang/servlet/xang/base64/
Without this fix the url could be a nice and simple
http://localhost:8080/xang/samples/hello/hello.xap/base64/ - but that would break.

Hey Mike,
So I'm getting closer on getting the sample to run. When I execute http://localhost/xang/hello.xap I just get the source of the page. So it seems likely that I've still got a disconnect between tomcat/xang making it use the xang servlet to process the page. Sound correct?
I can't believe how long this has taken to fumble through this.

I've found that the different versions of XML parsers between Tomcat and Xerces are causing problems.
The Xang code extends the xml Document class & I think there is a problem doing that when the base class is loaded by the default classloader & the Xang code is loaded by the 'change-aware' Tomcat classloader.
I was able to fix the problem by putting ALL Xang code in the classpath - in startup.bat or wherever. This includes the FESI JavaScript engine.
For example:
set CLASSPATH=%CLASSPATH%;%TOMCAT_HOME%\lib\xerces.jar
set CLASSPATH=%CLASSPATH%;%TOMCAT_HOME%\lib\xalan.jar
set CLASSPATH=%CLASSPATH%;C:\Jakarta\tomcat\webapps\xang\WEB-INF\classes
set CLASSPATH=%CLASSPATH%;C:\projects\apache\modules\xml-xang\java\classpath\fesi.zip;
Now, the next problem is my sample .xap files reference an out of date Xalan class.... onward and upward.

Mike,
What version of Tomcat do you prefer? Tomcat 3.2? 3.3? or 4?

Mike,
I don't have a servlet engine installed. I'll try to see if Tomcat is available for my platform. I'll also try to install it. I'm not comfortable with Java at all.
Below is information I sent to you earlier. It pretty much explains everything.
Thanks for getting back to me so quickly this time. Greatly appreciated.

Good gravy, you are exactly what I've been looking for...
Wonderful!
My AIM name is <JasonWohlford>. My ICQ number is <112823231>. Your welcome to chat with me on which ever. Right now, you'll find me on AIM more often.
I'll be able to help with development best between the hours of 8:30-5:00 p.m. CST at work. I have great flexibility from my wonderful employer Brian Belsterling, President of The Copy Center. As long as I can show, if asked, that I am benefiting The Copy Center and get the rest of my work done it will be fine. Therefore, I'd eventually like to convert my client-side JavaScript site at <SylvanOrder.com> to Xang.
I have a very strong understanding of JavaScript. I also understand XML to a reasonable degree. (Hey, what's really to understand.) I'm quite weak in XSL; and have almost no knowledge of Apache configuration. That being said, I love to code. I love to code to spec. I love XML, XSL, the DOM, and JavaScript and am passionate about them. They rock.
I accept and agree with the Apache license and am very interested in contributing to open source. Although I like Linux, I'm not much for the GPL. I do like the FreeBSD license very much, although I've never run straight FreeBSD.
This is my configuration is the tricky part. At work, I am running Mac OS X (based on many BSDs). It has Apache built in. According to Apple it also has a very strong Java2 environment. The Mac OS X box is what I'll be using most of the time. At home, I should have a Linux-Mandrake 8.0 box running this weekend. My replacement motherboard should be arriving today or tomorrow. It has telnet and maybe SSH access? How shall I proceed?

The installation instructions are a bit old & are on the apache site - I
will help you get it installed on whatever servlet engine you currently
have.
Xang is a Java servlet, which requires a servlet engine. I wrote it with
JServ, but have moved to Tomcat since then. There are a few
incompatibilities between servlet engines & between versions of the Java
servlet specification from Sun.
While we get this thing configured for you machine, tell me a bit about your
software environment & what you hope to do with Xang.
If you have an instant messaging client, we can chat during your
installation & I can work through any problems that might pop up.
Mike
Here are the instructions I wrote a long time ago:
===
The Apache Xang engine is currently implemented as a Java Servlet. You must
include xang.jar, xalan.jar, xerces.jar and fesi.zip in the Servlet class
path. Consult your Servlet engine documentation for detailed instructions.
The Xang servlet needs to be registered with your Servlet engine. The
servlet class name is: org.apache.xang.net.http.object.impl.HTTPObjectServer
The servlet initialization parameters are: config=full-path/to/your/xang.cfg
For the Apache JServ servlet engine, this is the configuration information
to place in zone.properties to register the Xang servlet:
servlet.org.apache.xang.net.http.object.impl.HTTPObjectServer.initArgs=confi
g=full-path/to/your/xang.cfg
In addition, the Web server or Servlet engine needs to be configured to pass
requests to files with a .XAP extension to the Xang servlet. Consult your
Servlet engine documentation for detailed instructions.
For the Apache JServ servlet engine, this is the configuration information
to place in zone.properties to register the Xang servlet:
servlet.org.apache.xang.net.http.object.impl.HTTPObjectServer.initArgs=confi
g=D:\projects\apache\modules\xml-xang\java\src\org\apache\xang\xap\xang.cfg
For the Apache JServ servlet engine, this is the configuration information
to place in the jserv.conf for getting the Xang servlet to handle .xap
files:
ApJServAction .xap
/servlets/org.apache.xang.net.http.object.impl.HTTPObjectServer
To run XSLT extensions, include bsf.jar and bsfengines.jar. All these JAR
files are distributed with Xalan. For extensions implemented in JavaScript
or another scripting language, see the Xalan extensions language
requirements to identify any additional JAR files you must place on the
class path and where you can get them.

Mike,
I've had dreams wanting something like what Xang does. I scoured the web for
months trying to find something that handles XML, XSL, and JavaScript. It
has huge potential!
I have some issues with the project. First, how in the heck do I install it?
Where's all the documentation. It seem quite sparse and difficult to
understand.
I want to work on this project. I'm extremely passionate about Xang. How can
I become involved!?

Re: Update to xang.war for Tomcat
Posted by Mark Puckett <ma...@yahoo.com>.
Okay, I put the xang.war file in the tomcat/webapps
dir, but it didn't *appear* to have any affect.
I was getting a class loader failure so I copied
xerces.jar and xalan.jar into the tomcat/lib dir and
rearranged my classpath as you suggested. I am,
however, still referencing xang.jar adn fesi.zip from
my xang installation.
Here is what I'm getting now:

By the way, perhaps I missed this somewhere along the
way, but trying to execute on port 8080 yields this
error, whereas port 80 still just shows me the .xap
source. Can I assume that I still have a diconnect
between apache and tomcat? Or do I always have to use
8080?
