loadStyle throws FacesException caused by DataFormatExceptio

[cprietom]

Hello,

When using <a4j:loadStyle src="resource:///stylesheet/corpme.xcss"/> I'm getting this exception:

javax.faces.FacesException: Error decode resource data

corpme.xcss is like this:

<?xml version="1.0" encoding="UTF-8"?>
<f:template xmlns:f="http:/jsf.exadel.com/template"
 xmlns:u="http:/jsf.exadel.com/template/util'"
 xmlns="http://www.w3.org/1999/xhtml" >

 <f:verbatim><![CDATA[
 body {
 background-color: #0000ff;
 }
 ]]></f:verbatim>

 <u:selector name=".myCssClass">
 <u:style name="font-size" skin="generalSizeFont" />
 <u:style name="font-family" skin="generalFamilyFont" />
 <u:style name="color" skin="generalTextColor" />
 </u:selector>

</f:template>

The generated HTML is like this:

<link class="user" href="/Visor/a4j/s/3_3_0.GAstylesheet/corpme.xcss/DATB/eAGbUnaFO3T5DGkAEaUDmQ__" rel="stylesheet" type="text/css" />

Is it OK? I'm using Richfaces 3.3.0.GA and deploying the application as an EAR in JBoss 4.2.2.GA. Taking a look at the structure of the deployment folder, the corpme.xcss file is located in deploy/Visor-ear.ear/Visor-app.war/stylesheet/corpme.xcss, and it looks like a4j:loadStyle is finding it because, if I change the path to a non-existing one (<a4j:loadStyle src="resource:///non/existing/path/corpme.xcss" />) the exception thrown is a ResourceNotFoundException.

What am I doing wrong?

Thank you in advance.

Hello,

Do you use any custom filters that affect URLs generation?

[cprietom]

I only use the org.jboss.seam.servlet.SeamFilter and a filter to control the session timeout, but it makes no modifications to the URLs.

<filter>
 <filter-name>SessionTimeoutFilter</filter-name>
 <filter-class>
 com.utils.SessionTimeoutFilter
 </filter-class>
 </filter>
 <filter-mapping>
 <filter-name>SessionTimeoutFilter</filter-name>
 <url-pattern>*.seam</url-pattern>
 </filter-mapping>

Has anybody managed to insert a XCSS file without problems? I still cannot use it: Is looks like it is found, but there is some kind of problem with the format of the file.

[nbelaevski]

I've tried to pass data string you've posted to locally run RF demo, works ok. Can you please provide answers to the following questions:

1. Does this happen for common component XCSS files?
2. Another strange thing: href="/Visor/a4j/s/3_3_0.GAstylesheet/corpme.xcss/DATB/eAGbUnaFO3T5DGkAEaUDmQ__" is generated without .jsf or .seam suffix. Can you please post details about Faces servlet mapping and also check whether generated URLs differ for custom styling and common component resources?

Sorry for wasting your time. I don't know why it failed, but it works now and I can't remember changing anything special.

Thanks for your time.
