the call to getResources with null resourceName is causing this error
referencing the javadoc for rev 117 located@
http://www.opensymphony.com/xwork/api/
getResources
public static Iterator<URL> getResources(String resourceName,
Class callingClass,
boolean aggregate)
throws IOException
Load all resources with a given name, potentially aggregating all results
from the searched classloaders. If no results are found, the resource name
is prepended by '/' and tried again.
This method will try to load the resources using the following methods (in
order):
From Thread.currentThread().getContextClassLoader()
From ClassLoaderUtil.class.getClassLoader()
callingClass.getClassLoader()
Parameters:resourceName - The name of the resources to loadcallingClass - The
Class object of the calling object
Throws:
IOException
but wait theres an open bug on this issue
http://mail-archives.apache.org/mod_mbox/struts-issues/200806.mbox/[EMAIL
PROTECTED]
but this bug that was quashed with the release of 2.1.3.GA
https://issues.apache.org/struts/browse/WW-2653
Op Noted that he wanted a default validators.xml to be read and a default.xml
if that did'nt work the patch is to make specific reference to resourceName of
com/opensymphony/xwork2/validator/validators/default.xml
(note the validator classes listed in default.xml)
<validators>
<validator name="required"
class="com.opensymphony.xwork2.validator.validators.RequiredFieldValidator"/>
if that fails the routine looks for validators.xml which contains a litany of
validators definitions e.g.
<validators>
<validator name="required"
class="com.opensymphony.xwork2.validator.validators.RequiredFieldValidator"/>
It is very likely you have a pre June 08 version of xwork so the choices are
1)resync with latest xwork and rebuild the latest xwork jars and redeploy to
all of your struts webapp(s)
2)pull down the struts libraries that have this xwork patch 2.1.3.GA and
redeploy to struts webapp(s)
//Here is a brief synopsis of mikes patch which will Parse default validator
configurations
String resourceName =
"com/opensymphony/xwork2/validator/validators/default.xml";
retrieveValidatorConfiguration(resourceName);
// Overwrite and extend defaults with application specific validator
configurations
resourceName = "validators.xml";
retrieveValidatorConfiguration(resourceName);
// Add custom (plugin) specific validator configurations
for (File file : files) {
retrieveValidatorConfiguration(file.getName());
}
so deploying from Struts 2.1.3.GA will fix this error..please let us know if
this is not the case
Thanks
Martin
