All,
We've been using Struts 1 (currently 1.3.10) happily for years, mostly
with a monolithic configuration file (struts-config.xml). Lately,
we've been splitting-out some of the <action> and global-forward
configuration into separate files. As a logical next step, I changed
this portion of our global configuration file:
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames"
value="/org/apache/struts/validator/validator-rules.xml,
/WEB-INF/our-validator-rules.xml, /WEB-INF/validate_W.xml,
/WEB-INF/validate_X.xml, /WEB-INF/validate_Y.xml,
/WEB-INF/validate_Z.xml" />
</plug-in>
into these two separate configuration lines in different
struts-[foo].xml files:
struts-config.xml:
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames"
value="/org/apache/struts/validator/validator-rules.xml,
/WEB-INF/our-validator-rules.xml, /WEB-INF/validate_W.xml,
/WEB-INF/validate_X.xml, /WEB-INF/validate_Y.xml" />
</plug-in>
struts-Z.xml:
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames"
value="/org/apache/struts/validator/validator-rules.xml,
/WEB-INF/our-validator-rules.xml, /WEB-INF/validate_Z.xml" />
</plug-in>
Both struts-config.xml and struts-Z.xml are mentioned in web.xml like
this:
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml,
/WEB-INF/struts-Z.xml</param-value>
</init-param>
(There are actually 7 different configuration files, but that is
really besides the point.)
While loading <message-resources> in separate files seems to work, it
appears that the use of the validator as a plug-in ends up clobbering
part of my configuration: only the validation rules loaded from
validate_Z.xml seem to have any effect. During startup, I can see INFO
messages indicating that the validation rules are being parsed from
all the files I expect:

org.apache.struts.validator.ValidatorPlugIn- Loading validation rules

I can see that the validation base rules (from Struts) plus our own
base validation rules are being loaded twice, but I figured that was
just a bit of wasted time.
Can anyone confirm that mentioning the validation plug-in in two
separate configuration files will result in only one of the
configuration files actually taking effect? If so, is there a way
around this, or am I required to use a single configuration file for
all my validation-specific configuration?
Thanks,
