The two problems preventing the Struts example (build 20001120) to work on
Orion (1.4.0) can be solved as follows:
1. javax.servlet.jsp.JspException: Missing resources attribute
org.apache.struts.action.MESSAGE error
The problem is caused by Orion not allowing access on resources (in this
case a resourcebundle property file) in the WEB-INF/classes folder. It seems
that the Servlet 2.2 spec. doesn't states clearly if this is allowed or not;
the Orion team decided to not allow access.
A simple solution is making the resources available through the (application
its) classpath.
By jarring the resources (e.g. the WEB-INF/classes folders) and putting this
jar in the WEB-INF/lib folder the resources can be found.
I would suggest the Stuts team to implement this solution for the struts
example as Orion is probably not going to change its behavior in this.
2. java.net.MalformedURLException: unknown protocol: jndi

As this requires changing the source, I kindly request that the Struts
development team could fix this also.

Struts 1.0 example (11/15 nightly) is not working on Orion (1.2.9) either.
It seems something is wrong with 'jndi' as it use jndi to resolve
'struts-config_1_0.dtd'.
Here is a common exception ...

Subject: org.apache.struts.action.MESSAGE exception with orion 1.4
Hi all,
I've encountered the ever-popular Missing resources attribute
org.apache.struts.action.MESSAGE error when trying to access the
struts-example application using Win NT, orionserver 1.4, jdk1.3 and struts
from 13Nov. I've searched through the struts message archives and tried all
the suggestions I could find, but still no luck. (I was able to deploy the
example on JRun 3.0, but not on orionserver.)
Any help will be greatly appreciated because I definitely want to use
orionserver instead of JRun.
Here's the error:
javax.servlet.jsp.JspException: Missing resources attribute
org.apache.struts.action.MESSAGE
at
org.apache.struts.taglib.bean.MessageTag.doStartTag(MessageTag.java:232)

Here's my application.xml entry:
<web-module id="strutsExample"
path="d:\struts\webapps\struts-example.war"/>
Here's my default-web-site.xml entry:
<web-app application="default" name="strutsExample"
root="/struts-example"/>
Orion is at d:\orion and struts is at d:\struts.
Thanks,
Denis Hanson
