XML file included into validation.xml via entity reference not found 

           Summary: XML file included into validation.xml via entity
                    reference not found
           Product: Commons
           Version: 1.0.2
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Validator
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: cordsmeier@gmx.de


I tried to put the formset constants normally defined in the validation.xml 
file into a separate file and include it via an ENTITY reference into the 
validation.xml file. The reference was declared as follows:

<!DOCTYPE form-validation PUBLIC
          "-//Apache Software Foundation//DTD Commons Validator Rules 
Configuration 1.0//EN"
          "http://jakarta.apache.org/commons/dtds/validator_1_0.dtd" [
	<!ENTITY formsetconstants SYSTEM "formsetconstants.xml">
]>

<!-- ....... -->

and included as follows:

    &formsetconstants;

The included file was placed into the web-inf directory (like the 
validation.xml) of the web application which was deployed on a tomcat 4.1.24. 
As defined in the W3C XML specifications, the referenced file must be searched 
relative to the file in which it is referenced. However, the tomcat tried to 
locate the file in its "bin" directory and has thrown the following exception:


2004-02-19 09:26:40,042 ERROR  [ValidatorPlugIn.initResources: 224]

The file is found and everything works well if I put an absolute path into the 
entity reference but I can't do that because I don't know where the tomcat 
lives on the target system. 

The same feature works well with the struts-config.xml which also uses the 
digester to read the file. I compared the validator and struts source code but 
couldn't find the problem.
