Hi List!
I'm trying to get started with struts (1.1) step by step.
I had a working frameset made from *.JSPs in Tomcat 3.23 (The JSPs don't
actually do anything at this stage, they're like static html).
Then I inserted the
<html:base/>
tag in one of the JSPs, together with the
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
At first, my web.xml only had the
<taglib>
<taglib-uri>/tags/struts-bean</taglib-uri>
<taglib-location>/WEB-INF/struts-bean.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>/tags/struts-html</taglib-uri>
<taglib-location>/WEB-INF/struts-html.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>/tags/struts-logic</taglib-uri>
<taglib-location>/WEB-INF/struts-logic.tld</taglib-location>
</taglib>
When that didn't work, I figured the actionServlet must probably be required
and added
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>/do/*</url-pattern>
</servlet-mapping>
The struts-config.xml is where it should be, but pretty empty, like this:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts
Configuration 1.0//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd">
<struts-config>
</struts-config>
The Struts 1.1 libs , taglibs, and dtds are all where they should be, AFAIK
.
I figured, as at this stage I'm only using STRUTS in the one tag above, and
not actually invoking the ActionServlet, the app should work without setting
up any ActionForwards and so on.
Is that correct?

Thanks for the script, Oswald!
I did manually check the presence of all the required stuff once tomcat had
unpacked the war file.
struts.jar is in WEB-INF/lib, together with all the other *.jar s from
struts 1.1, all the *.tld and *.dtd from struts 1.1 are in WEB-INF, and web.xml
and struts-config.xml are in WEB-INF, too.
I had actually downloaded the sources and looked at the
PropertyMessageResourcesFactory, but I couldn't figure out what it needs that's not there.
I suspect that some entries in either web.xml or in struts-config are
required that I didn't put in there, or maybe some properties file?
Kind regards
Lukas

Hello, Lukas:
Here's a simple script that can be helpful in these situations:
+++++++++++++++++++++++++++++++++++++++++++
for jar in `ls *jar`
do
echo "checking $jar..."
jar tvf $jar | grep "org.apache.struts.util.PropertyMessageResourcesFactory"
done
+++++++++++++++++++++++++++++++++++++++++++
When I checked WEB-INF\lib under a struts-based web
application on my system, it produced the following output:
#################################################
checking commons-beanutils.jar...
checking commons-collections.jar...
checking commons-digester.jar...
checking commons-fileupload.jar...
checking commons-lang.jar...
checking commons-logging.jar...
checking commons-validator.jar...
checking jakarta-oro.jar...
checking struts.jar...
749 Sun Jun 29 21:46:38 PDT 2003 org/apache/struts/util/PropertyMessageResourcesFactory.class
#####################################################
Perhaps you are missing struts.jar?
btw: if you are on Windows, you can download either Cygwin
or uwin (if you prefer ksh)....
Cordially,
Oswald
