HI,

unfortunatly running a simple jsf application causes always the following exceptions:

type Exception report

message

note The full stack trace of the root cause is available in the Apache Tomcat/5.5 logs.

It happens while stepping on the first <f:view> tag.

I call the the *.faces page.

Could you please help?

Thanks in advance.

Kind Regards
Oliver

You should access JSF mappings using the faces extension instead of JSP. I.e. if you have file mypage.jsp you should access it using mypage.faces.

[Oliver_Anders]

I’m actually doing this and I understood, that

org.apache.jasper.JasperException
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:370)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)
javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
com.sun.faces.context.ExternalContextImpl.dispatch(ExternalContextImpl.java:322)
com.sun.faces.application.ViewHandlerImpl.renderView(ViewHandlerImpl.java:147)
com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:87)
com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:200)
com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:117)

javax.faces.webapp.FacesServlet.service(FacesServlet.java:198)

org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81)

within the Exception stack means that the FacesServlet is called. What else can cause the error?

Kind Regards,
Oliver

I don’t know what this problem can be – can you try to generate page in your project using or JSF template and see if it opens when you deploy it to the server?

Can you attach the JSP contents? Do you use some JSP include or redirects?

[Oliver_Anders]

Hi,

this seems to be a JBOSS problem. I removed ….\jboss-4.0.3SP1\server\default\deploy\jbossweb-tomcat55.sar\jsf-libs which contains myfaces libs, deleted temporary directories (tmp, data, ..) of the server and it worked.

I will try out how to integrate myfaces later.

Thanks for your help.

Kind Regards
Oliver

Thanks for your information – we’ll keep an eye on MyFaces + JBoss combo – maybe there’s something we can do to avoid problems.
Were you using MyFaces 1.0.9? Maybe JBoss is bundling 1.1.1?

[Oliver_Anders]

Hi,

Jboss is bundling 1.1-something. Myeclipse is bundled with 1.0.9.

For whatever reason this seems to lead to compatiblity problems while using the Sun JSF reference implementation. maybe jboss activates the myfaces servelet??

However, the jboss manual gives a hint to remove the directory if you want to implement a sun JSF application. Anyway, at the moment I’m more interested in running a 1.1 something jsf version and myeclipse is supporting myfaces only in version 1.0.

Getting JBOSS plus myfaces 1.1something plus myeclipse running would be a nice thing, you could keep on. 🙂

Kind regards,
Oliver

MyEclipse 4.1M2 also allows you to pick MyFaces 1.1.1 as a JSF implementation.

[Markus Brose]

Hi,
I have the same problem as Oliver, but I can not take the solution path, he took:

this seems to be a JBOSS problem. I removed ….\jboss-4.0.3SP1\server\default\deploy\jbossweb-tomcat55.sar\jsf-libs which contains myfaces libs, deleted temporary directories (tmp, data, ..) of the server and it worked.

Since I’m dependend of an Internet Provider I can not tell the provider to delete a directory of his JBoss installation just for me.
So please, please, please follow up on this, I need a different solution.

Thank you
Markus

[support-eugene]

Markus, did you try the MyFaces 1.1.1 bundled with MyEclipse 4.1M2?
