JSF in Struts.

[Rajeev Ravindran]

Hi,

Not sure wheather to post this question in Struts or JSF forum.

I have a Struts application running in production and i want to include a new functionality to it, we are planning to do the new fucntionality in JSF as we are more into JSF now. I tried to define a JSF page in tiles-defs.xml, but its thorwing exception at runtime

This is my tiles definition.

  
  <definition name=".manageDisplay" extends=".layoutDefinition">
    <put name="title"
    value="Manage Information" />
    <put name="body" value="/jsfTest.jsp" />
  </definition>

this is the exception trace.

[ServletException in:/jsfTest.jsp] Cannot find FacesContext' javax.servlet.jsp.JspException: Cannot find FacesContext at javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:399) at com.sun.faces.taglib.jsf_core.ViewTag.doStartTag(ViewTag.java:106) at com.ibm._jsp._jsfTest._jspx_meth_f_view_0(_jsfTest.java:102) at com.ibm._jsp._jsfTest._jspService(_jsfTest.java:79) at com.ibm.ws.jsp.runtime.HttpJspBase.service(HttpJspBase.java:88) at javax.servlet.http.HttpServlet.service(HttpServlet.java:856) at com.ibm.ws.webcontainer.servlet.ServletWrapper.service(ServletWrapper.java:1212) at com.ibm.ws.webcontainer.servlet.ServletWrapper.handleRequest(ServletWrapper.java:629) at com.ibm.wsspi.webcontainer.servlet.GenericServletWrapper.handleRequest(GenericServletWrapper.java:117) at com.ibm.ws.jsp.webcontainerext.JSPExtensionServletWrapper.handleRequest(JSPExtensionServletWrapper.java:171) at com.ibm.ws.jsp.webcontainerext.JSPExtensionProcessor.handleRequest(JSPExtensionProcessor.java:230) at com.ibm.ws.webcontainer.webapp.WebAppRequestDispatcher.include(WebAppRequestDispatcher.java:552) at org.apache.jasper.runtime.JspRuntimeLibrary.include(JspRuntimeLibrary.java:1034) at org.apache.jasper.runtime.PageContextImpl.include(PageContextImpl.java:475) at org.apache.struts.tiles.TilesUtilImpl.doInclude(TilesUtilImpl.java:137) at org.apache.struts.tiles.TilesUtil.doInclude(TilesUtil.java:177) at org.apache.struts.taglib.tiles.InsertTag.doInclude(InsertTag.java:756) at org.apache.struts.taglib.tiles.InsertTag$InsertHandler.doEndTag(InsertTag.java:881) at org.apache.struts.taglib.tiles.InsertTag.doEndTag(InsertTag.java:473) at com.ibm._jsp._defaultLayout._jspx_meth_tiles_get_2(_defaultLayout.java:163) at com.ibm._jsp._defaultLayout._jspService(_defaultLayout.java:87) at com.ibm.ws.jsp.runtime.HttpJspBase.service(HttpJspBase.java:88) at javax.servlet.http.HttpServlet.service(HttpServlet.java:856) at com.ibm.ws.webcontainer.servlet.ServletWrapper.service(ServletWrapper.java:1212) at com.ibm.ws.webcontainer.servlet.ServletWrapper.handleRequest(ServletWrapper.java:629) at com.ibm.wsspi.webcontainer.servlet.GenericServletWrapper.handleRequest

PS :
If i try to run jsfTest.jsp directly, it will run fine. It make me feel like my JSF configuation for the web app is working good..

In the web xml, i set load-on-startup for "javax.faces.webapp.FacesServlet" to 1. so it should have initialized at startup !

Can anyone help me with this ? Im thinking to implement the new funtionality in struts itself. Will it to be good to go with JSF just for one new functionality ? Appretiate any suggestions.

Thanks,
Rajeev

I'm a consultant and have worked on many projects that I didn't start and won't finish. I learned a long time ago that even if I totally hate the framework the application was built in, it's best to "go with the flow" of the current application. Implementing a single page in a different framework makes nothing but trouble for you and for any other developers trying to maintain this application in the future. Unless you're planning to rewrite the entire applicatoin in JSF, my advice is to just do the page in Struts.
