facelets - JSF: Serving Resources From a Jar -

i´m in process create couple of jars packed facelets templates usage through organisation.

stuck in jsf 1.2 functionality not come out of box. stack:

• jboss eap 5.1
• seam 2.2
• richfaces 3.3.3

it seems me need 2 resources:

1. resource resolver finds faclets resources
2. a thing serve css , js resources jar

resource resolver seems easy part: http://ocpsoft.org/opensource/create-common-facelets-jar/

the thing streams css / js more complicated: jsf: serving resources jar http://cagataycivici.wordpress.com/2006/05/09/jsf_serving_resources_from_a/

• phaselistener
• filter
• servlet
• weblets

i use weblets seems project dedicated solve problem. furthermore recommended in cool jsf book bought: "pro jsf , ajax building rich internet components"

the problem can not find stable release in maven repo , no documentation. in example no faclets not used:

https://github.com/werpu/weblets

in article above filter highlighted solution. http://myfaces.apache.org/tomahawk-project/tomahawk/apidocs/org/apache/myfaces/webapp/filter/extensionsfilter.html

sadly not simple task hook in solution. not have time (or knowledge @ moment) :(

possible can use project: http://jawr.java.net/introduction.html jawr aims bundle js , css files.

the project wiki indicates possible: http://jawr.java.net/docs/generators.html see "classpath resource generator" section.

please advice :)

hello load css, js etc jar use following.

if want load faclets jar use custom defaultresourceresolver

/**  * används för hämta hämta xhtml filer från jar filen  * @author ldc-jha  *  */ public class classletsresourceresolver extends defaultresourceresolver implements resourceresolver{      public classletsresourceresolver() {         super();     }      private static final string prefix = "/framework/";     private static final string layout = "/layout/";      public string getprefix() {         return prefix;     }      public url resolveurl(string path) {         final string prefix = getprefix();         system.out.println("resolveurl()"+path);         url url = null;         if (path != null && path.startswith(prefix)) {             final string resource = path.substring(prefix.length());             url = getclass().getclassloader().getresource("xhtml/framework/"+resource);         }          if (path != null && path.startswith(layout)) {             system.out.println("layout:"+path);             url = getclass().getclassloader().getresource("xhtml/framework"+path);             system.out.println(url);         }          if(url != null){             return url;         }         else         {             return super.resolveurl(path);         }     } }  

if want load resourceresolver wihtout editing xhtml can this.

@weblistener public class simpleservletcontextlistener implements servletcontextlistener{      private static final logprovider log = logging.getlogprovider(simpleservletcontextlistener.class);       public void contextinitialized(servletcontextevent event){                         event.getservletcontext().setattribute("facelets.resource_resolver","se.lu.ldc.core.reslover.classletsresourceresolver");  } 

}

you might have let seam know faclets well, let me know if there problem. had same idea, , got working packing css, xhtml etc in jar.
