Cannot find FacesContext
Hello everyone
I am rather new to jsf and I have run into a big black hole ;-)
After I have deployed my app. and I call my bankUI.jsp through my jsf mapping I get the following error:
javax.servlet.jsp.JspException: Cannot find FacesContext
javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:405)
org.apache.myfaces.taglib.core.ViewTag.doStartTag(ViewTag.java:71)
... rest of stacktrace ....
This is my setup:
App.server: jboss-4.0.4RC1
web.xml:
<!-- Faces Servlet -->
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Faces Servlet Mapping -->
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>

There are no errors on deployment, and my app. runs find. But when i try to acces my bankUI.jsp i get the error above.
And I do go through the correct jsf mapping http://localhost:8080/project_1app/bankUI.jsf
Now if I remove all my jsf related tags from my jsp file (bankUI.jsp) the page is displayed correct. So the error occurs when i hit the first jsf tag on my jsp page.
I also run ejb3.0 on my jboss app server. I don't know if that is usefull information.
PLEASE HELP

Your web.xml appears to be missing the necessary listener entry. Try adding:
<listener> <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>
in the appropriate place and see if that resolves your issue.

hello PeterMGoldstein
Thank you for your reply. Unfortunatly it did not work. I added the lines you specified as follows:

I get the same errormessage as before.
The deployment of my app looks like this in the serverconsole:

There is an error on deploy, that i don磘 understand. Maybe you have seen this before?

The locale error is easy - it means that you're missing a locale-config like this one in your faces-config.xml:
<locale-config>
<default-locale>en_US</default-locale>
<supported-locale>en_US</supported-locale>
<supported-locale>en</supported-locale>
<supported-locale>es_ES</supported-locale>
<supported-locale>es_US</supported-locale>
<supported-locale>es</supported-locale>
</locale-config>
Check the faces-config.xml schema for details.
As for your other problems, make sure you don't have multiple versions of the JSF libs in your app. If you're running on JBoss, you'll likely have all the JBoss libs in $JBOSS_HOME/server/default/deploy/jbossweb-tomcat55.sar/jsf-libs
If you package another set of JSF libs in your WEB-INF/lib directory this can cause the kind of problem you're seeing. So, in short, make sure that the above directory contains the MyFaces JSF impl and ensure that you're not packaging another set of JSF jars in your ear.

what is thr url in your browser? i think the problem is with web.xmltry using *.faces instead of *.jsf in the url pattern one more try is useyourpojectfolder /yourjsfile.faces
Hi
You should rename your blank.jsp to blank.jsf
to ensure it matches your servlet-mapping as you have in your web.xml "*.jsf"
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
Hey PeterI will try this at once....Ralph
Hallo again Peter
You are a star !!!!!!! ;-)
This solved the problem. My faces .jar files in web-inf/lib was not the same as the ones in jbossweb-tomcat55.sar/jsf-lib.
When I copied the same faces jars to web-inf/lib the there were no errors.
THANK YOU VERY MUCH. You have been a huge help.
Regards Ralph
Ralph,
Glad I was able to help.
BTW, you don't even need to have the JSF/MyFaces jar files in your WEB-INF/lib. JBoss' classloader will load them from the jsf-libs directory in deploy/jbossweb-tomcat55.sar. This is the setup I use, and it helps minimize class collision problems. The only possible issue is that you have to include a reference to this JBOSS_HOME subdirectory in your build.xml, but this is fairly straightforward. See any of the JBoss sample apps that use JSF for a concrete example.
Regards,
Peter
Hello, Good day.
By the way, Which IDE u are using?
And what you would suggest me, which have better design view support with other functionality for JSF development on JBOSS?
I am asking u this bcoz you are using JBOSS and there are some IDEs which doesnt directly support JBOSS (like sun Creator 2), or it might be i dont know, if it does. So please help me out.
Have a nice day.
