    [ https://issues.apache.org/jira/browse/MYFACES-2442?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12846492#action_12846492 ] 

Leonardo Uribe commented on MYFACES-2442:
-----------------------------------------

On latest myfaces core impl code we have this package as imported:

org.apache.jasper.compiler;resolution:=optional

this solves the problem you describe, so I'll close this one as duplicate. Thanks for your report.

> Hello,
> We detect a problem when using MyFaces 1.2.2 within an OSGi container. The problem occurs when MyFaces tryies to initialize the default JspFactory from the Jsp21FacesInitializer class. It seems that the code which poses problem is the following:
>  if (jspFactory == null) {
>             // TODO: this Class.forName will be removed when Tomcat fixes a bug
>             // also, we should then be able to remove jasper.jar from the deployment
>             try {
>                 Class.forName("org.apache.jasper.compiler.JspRuntimeContext");
>             } catch (ClassNotFoundException e) {
>                 ; // ignore
>             } catch (Exception ex) {
>                 log.debug("An unexpected exception occured "
>                         + "while loading the JspRuntimeContext.", ex);
>             }
>             jspFactory = JspFactory.getDefaultFactory();
>         }
> As a matter of fact, the getDefaultFactory method returns null in this context...
> If we force MyFaces to use the Jsp20FacesInitializer class from the ContainerUtils class as following:
> public class ContainerUtils
> {
>     /**
>      * Determines whether we're running in a Servlet 2.5/JSP 2.1 environment.
>      * 
>      * @return <code>true</code> if we're running in a JSP 2.1 environment,
>      *         <code>false</code> otherwise
>      */
>     public static boolean isJsp21()
>     {
>         /*try 
>         {
>             // simply check if the class JspApplicationContext is available
>             Class.forName("javax.servlet.jsp.JspApplicationContext");
>             return true;
>         } 
>         catch (ClassNotFoundException ex) 
>         {
>             ; // expected exception in a JSP 2.0 (or less) environment
>         }*/
>         
>         return false;
>     }
>     (...)
> }
> the problem doesn't occur and MyFaces can be used.
