Is a parser required to run STRUTS?
I recently tried to load our application to another user's machine and am
curious what all is required. I put the struts.jar in Web-inf\lib and made
sure all tlds, struts-config and web.xml were all in the correct place
(identical to my environment which run fine).
All needed classes are compiled (with reference to struts.jar) and appear
under Web-inf\classes in their respective package structures.
However, I am receiving the following errors and wonder if something else
(maybe jaxp or other parser) is required to JUST RUN STRUTS web app?
The following error is appearing in the tomcat console when tomcat is
started (is Web-inf case sensitive?):
2001-03-14 12:25:24 - Ctx( /best ): Unsafe path G:\BestPilot\src\trs\best
/WEB-INF/struts-config.xml
cannot load servlet name: controller
Then when trying to retrieve a jsp:

i've gotten this error before. and from looking at what you typed. you
need to capitalize your web-inf folder to WEB-INF.

>From the installation page on the Struts web site:
XML Parser - Struts requires the presence of an XML parser that is compatible
with the Java API for XML Parsing (JAXP) specification, 1.0 or later. You can
download and install the JAXP reference implementation, which is required for
building the Struts source distribution. In Struts-based web applications, you
may replace the reference implementation classes with any other JAXP compliant
parser, such as Xerces. See detailed instructions related to the parser in the
instructions for building and installing Struts, below.
