Use of filter to JSF faces servlet

Hi
I have a JSF application which is secured by a custom security framework (similar to SITE MINDER). The security framework after authentication passes the authenticated user name within a in-memory session cookie.
The entire user information like his group and access restrictions (field / UI compoonent level) resides in the application database
I have used a filter to JSF Faces servlet to retrieve the user information from the database and storing in session.
Is this use of filter a good approach?

I would fetch such information only once and store it in a simple session scoped bean after a successful login, but I am weird for wanting to do things in a simple way.
A filter can work to validate if the user is still "logged in" (IE. his/her session didn't expire), but since this is JSF you could also use a phase listener for such a purpose.

ADF Bindings Servlet/Filter not invoking Faces Servlet

I'm getting ADF Faces and Facelets working properly with pages written in jspx format, but the Faces Servlet being mapped to jsf format.
The problem I'm getting is while displaying ADF Tables with data retrieved from the database using Toplink and bindings provided by ADF Databindings.
The following is the Web.xml mappings for Faces Servlet and ADF bindings filter:
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>resources</servlet-name>
<url-pattern>/adf/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<filter>
<filter-name>adfBindings</filter-name>
<filter-class>oracle.adf.model.servlet.ADFBindingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>adfBindings</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>adfBindings</filter-name>
<url-pattern>*.jspx</url-pattern>
</filter-mapping>
I'm getting the ADF tables displayed using ADF Bindings, if the faces servlet is mapped for jspx format;but, at the cost of losing Facelets...Facelets is not working with Faces Servlet mapped to jspx format(though written in jspx format, the faces servlet mappping has to be made for jsf format.On the other hand, if I use faces servlet mapping for jsf pages I'm getting Facelets working but ADF Databindings are not working ,(I guess) and hence ADF Faces Tables are not being displayed(I'm getting Access Denied message).
I even tried to change the ADF binding filter mappings
---- from ---- jsp &jspx---- to ----- jsp and jsf ----
But I got the same Access denied message.
I read a similar post on this forum by Mr.Ashish Kumar who said he is using java script and automatic form submission, to refresh the page and that gave him the table working.
as quoted in the post:
af:table displays Access Denied
Why should the page be refreshed at all. I Guess , the Faces Servlet is not being invoked by the ADF Bindings Filter/Servlet, and for this , I suppose , Mr.Ashish is using java script to provide the action required.
And one more thing which that Automatic Refreshing of page using JavaScript cannot do.
Suppose,
I need customised display, rather than just a Table or Form,like:
public String getEmp() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("findAllEmp");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
List<Emp> res=(List<Emp>)result;
for(int i=0;i<res.size();i++)
Emp myrec=res.get(i);
System.out.println("Employee ["+myrec.getEname()+"], Salary ["+myrec.getSal()+"]");
return "";
where I do some customisation in the backing bean.
and I call that method binded to a button as below:
<af:commandButton
text="findAllEmp"
disabled="#{!bindings.findAllEmp.enabled}"
binding="#{backing_Success.commandButton1}"
id="commandButton1"
action="#{backing_Success.getEmp}"/>
What I'm getting is a disabled button.
Why doesn't ADF bindings servlet invoke the faces Servlet?
Can't we make ADF Bindings Servlet invoke Faces Servlet by configuring in the web.xml?
Can't we get ADF Bindings filter mapped to work with jsf pages?
Won't ADF Bindings work with jsf pages, will they work only with jspx pages?
ADF Team,
Please Help me.
Thanking you,
Samba

Hi! Frank,
Thankyou for your Reply.
Yes, Mr.Adam Winer has contributed that library, I guess.
But I already have that adf-facelets.jar in my lib folder ; and with out that the Facelets won't work with ADF faces , in the first place.
I'm getting Facelets working excellently with ADF Faces but I'm not getting ADF Bindings working with Faceletpages.
The thing is even in another application which does not have facelets in it, if we use mapping for jsf pages, ADF Bindings are not working.
I think the ADF bindings filter is configured some where to work with jspx pages only.Could you tell me where to change that entry to make ADF Bindings work with jsf extension?
Thanking you,
Samba.

What am I still missing here? I really want to start using JSF!
Regards,
Peter

I believe I have found the issue to the problem. The issue seems to be Weblogic is not respecting part of the Servlet 2.3 spec. It states that all ServletContextListener implementations should be called before the Servlet's init method is called. Tomcat respects this and that's why JSF works when deployed in Tomcat. Weblogic 8.1 calls this instance AFTER the Servlet's init's methods are called. This results in a NullPointerException being thrown.
 You can see how the ordering changes between Weblogic and Tomcat for yourself by editing the log4j.properties file and add the following:
log4j.category.com.sun.faces.config = DEBUG, config log4j.additivity.com.sun.faces.config=false
log4j.appender.config = org.apache.log4j.ConsoleAppender log4j.appender.config.layout = org.apache.log4j.PatternLayout log4j.appender.config.layout.ConversionPattern = ...
 Deploy the example application to both Weblogic and Tomcat and observe the order.
 I've developed a work around for this issue. Weblogic seems to respect the <load-on-startup> element in the web.xml file. I have written a Servlet which manually loads the ServletContextListener for JSF. The code below:
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import javax.faces.FactoryFinder;
import javax.faces.lifecycle.LifecycleFactory;
import javax.servlet.ServletConfig;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
public class WeblogicHackServlet extends HttpServlet {
public static final String CONFIGURE_LISTENER_KEY = "CONFIGURE_LISTENER"; public static final transient Log logger = LogFactory.getLog(WeblogicHackServlet.class);
public void init(ServletConfig servletConfig) throws ServletException {
LifecycleFactory factory =(LifecycleFactory)
FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
if (factory != null)
return;
String className = servletConfig.getInitParameter(CONFIGURE_LISTENER_KEY);
if (className == null) {
logger.fatal("Did not find the init parameter " + CONFIGURE_LISTENER_KEY);
return;
try {
Class aClass = Class.forName(className);
ServletContextListener listener = (ServletContextListener)
 aClass.newInstance();
listener.contextInitialized(
 new ServletContextEvent(servletConfig.getServletContext()));
} catch (Exception e) {
logger.fatal("The ConfigureListener could not be triggered", e);
 The web.xml file also needs to be changed to the following:
<servlet>
<servlet-name>WeblogicHackServlet</servlet-name>
<servlet-class>WeblogicHackServlet</servlet-class>
<init-param>
<param-name>CONFIGURE_LISTENER</param-name>
<param-value>com.sun.faces.config.ConfigureListener</param-value>
</init-param>
<load-on-startup> 1 </load-on-startup>
</servlet>
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup> 2 </load-on-startup>
</servlet>
This causes JSF to load properly. Hopefully, BEA can resolve this issue so my hack can be removed.

Faces Servlet no getting called when accessing JSF portlet

Hi,
I have a JSF web application and I am exposing the functionality of this JSF web application using native Weblogic Portal JSF portlets. I have configured this JSF web application as a simple producer and I am consuming these portlets in my portal using WSRP.
I have written a custom FacesServlet and configured it in the web.xml of the producer web application. When I access the pages in the producer web app like a normal web app, I see that my faces servlet is being called but when I consume these pages via the JSF portlet and view the portlets in the portal then the Faces servlet is not being called.
Is this normal behavior or is WSRP causing this problem or am I missing something. Your help is greatly appreciated.
Regards,
Hitesh

Hi Hitesh,
What I was asking you to give a try was, configure the standard faces servlet for example if you are using JSF RI
the configuration will look like
 <servlet>
 <servlet-name>FacesServlet</servlet-name>
 <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
 <load-on-startup>100</load-on-startup>
 </servlet>I am not very sure whether this can solve the problem.
Thanks

What can I do so solve this problem in my WAS ND 6.1.0.13? What could be the problem?

Faces Servlet not loaded in Oracle AS 10g 10.1.2

I have a created a very simple application using JDeveloper 10.1.3.4 on JSF. I deployed this application to Oracle AS 102 R.2 (10.1.2) ... no error occures while deployment. But I am unable to run this application , as no URL patterns are working ... plus in the OEM, the application is not loaded (Faces Servlet is not loaded) ... Although in web.xml its mentioned to load the servlet autometically, but not working... Can any one helps me...

I've just tested it with my 10.1.2 installation without problems.
Be aware that you
- use JDK 1.4.2 in JDeveloper
- use J2EE 1.3 while developing JSF pages
- have the ADF runtime installed on the AS
- should use URLs like http://host:port/contextroot/faces/page.jspx

Hi Steffen,
Thanks for promt response.

But now I am getting The website cannot display the page error.
Please clarify me if anything is wrong from my side. And also pl let us know which configurations I have to check for fixing the issue.

Understanding Faces Servlet Mapping

Hi guys, I would like understand how work the Faces Servlet mapping.
In a web.xml file I put
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.context.webapps.FacesContext</servlet-class>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern> /<my_app_context>/* </url-pattern> 1) If I put "/my_context/*" everything below "my_cotnext" (include JSP) is throughout to faces servlet, isn't?!!? can I just acces "http://localhost/my_context/index.jsp?!??
2) If i put "/faces/*" and use the URL "http://host/faces/my_context/index.jsp" I need to create a folder call faces inside "$CATALINA_HOME/webapp" ?!?!?
If not, what occurs?!!??
3) If i put "*.faces" can I save my jsp file with the extension jsp, for example index.jsp at context my_context, and before access by URL "http://localhost/my_context/index.faces"?!? If I can, how the tomcat find the index.jsp
Well, if someone can exaplain this rules in Tomcat for me will be very great!!!!!
Thanks all

Hi Gisard,
as far as I did understand the whole thing you have two possibilities
1. Path Mapping
2. Extension Mapping
I'm using Path Mapping, so I have the following entry in my web.xml:
<servlet>
 <servlet-name>Faces Servlet</servlet-name>
 <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
 <load-on-startup> 1 </load-on-startup>
</servlet>
<servlet-mapping>
 <servlet-name>Faces Servlet</servlet-name>
 <url-pattern>*.jsf</url-pattern>
</servlet-mapping>That's quite easy to use, because in my navigation rules in the faces-config.xml I just use something like this:
<navigation-rule>
 <navigation-case>
 <from-outcome>installation</from-outcome>
 <to-view-id>/pages/installation/inst_index.jsf</to-view-id>
 </navigation-case>
</navigation-rule>And I have the page "inst_index.jsp" in my folder "web-app-context/pages/installation".
I can access it with the URL:
"http://localhost:8080/<web-app-context>/pages/installation/inst_index.jsf".
If you want to use path mapping you should have the following entry in your web.xml:
<servlet>
 <servlet-name>Faces Servlet</servlet-name>
 <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
 <load-on-startup> 1 </load-on-startup>
</servlet>
<servlet-mapping>
 <servlet-name>Faces Servlet</servlet-name>
 <url-pattern>/faces/*</url-pattern>
</servlet-mapping>So for example if you want to access the page "inst_index.jsp" in the folder "web-app-context/pages/installation" you have to use the URL:
"http://localhost:8080/<web-app-context>/faces/pages/installation/inst_index.jsp".
But you don't need a new folder "faces" within your web-app.
I hope I could help you with that.

Servlet Faces Servlet is currently unavailable

Hi,
I get the following error when deploying my webapp to Tomcat 4.0:

Please help.

The jsf-ri.jar is copied in $tomcat_home/common/lib
(to solve the ConfigListener error) and following
libraries are a part of web-inf/lib:
commons-beanutils.jar, commons-collections.jar,
commons-digester.jar, commons-logging.jar,
jsf-api.jar, jstl.jar, standard.jar.
If you copy jsf-ri.jar into common/lib, you should copy all of the others as well (and remove them from your web application). However, you should also know that if you are really using Tomcat 4.0.x there are several class loader problems that will make it virtually impossible for this to run correctly. I would strongly recommend updating to Tomcat 5.0.16 (recently released stable implementation of Servlet 2.4 and JSP 2.0).
It's also possible to get the beta release of JSF to work on Tomcat 4.1.29 (see the release notes for details) but you will need to be sure you're using JSTL 1.0 instead of 1.1.

Garbled images when passed through faces servlet

hello.
I have pages whose image get completely garbled if they are displayed using the /faces/blaah.jsp path, but are not if displayed as /blaah.jsp
whatever the browser and the method to display them, they are always destroyed when the servlet routes them.
I googled here and there but found nothing about it.
Is it a known problem?
Thanks.

Nope, never heard of such a problem. That's very strange.
Are there any weird coincidences, such as the image name being the same as a faces page name. i.e. blaah.jsp and blaah.gif. And perhaps you are somehow routing the image through the faces servlet as well. i.e. /faces/blaah.gif instead of /blaah.gif.
Beyond that... Some details on your JSF version and a code snippet of how you are displaying your image will help.

Use request attributes in JSF

Is there a way we can pass data from one form bean to the other using request attributes insted of session attributes?
I am able to work with session attributes using
HttpSession mySession = (HttpSession) FacesContext.getCurrentInstance().getExternalContext().getSession(true); and setting attributes to it, but getting null pointers(occassionally) when I retrieve the atribute and work with it.
getSession(false) isnt helping either.
Looks like facesServlet is creating a new request when it forwards to next page. Any idea on how to get the Faces Servlet do something like request despatcher forward, for navigation so I can work with request attributes?
Appreciate your input.

Can I have just one backing bean and use it for all jsps in the app? App has 4 flows from home page and mutiple jsps in each flow. Each jsp has multiple form fields. Is that OK?
Any way to passing data/objects between different backing beans - other than using session attributes? I had similar problems working on Struts app as well.

Using a filter with selection?

Hello, I am using CS6 extended with windows7 and am pretty new to Photoshop. What I am trying to do with a portrait image is use the Filter/Stylize/Diffuse/Anisotropic on everything but the face. I want to kee the face sharp but I love the effect the diffuse has on the hair and background. I've been messing around with this for a few days and haven't come up with a solution othe than cutting the selection of the face, applying the filter then pasting the face back on but because of the filter it leaves a grey edge at the cut line. I'm sure there is a simple process that I'm missing. Any help would be much appreciated:) Thank you for your time:)

All you need to do is right click on your layer, and click "convert to smart object." Then apply the filter. You'll then see a little white box below your layer. This is known as a layer mask. Click on the white box (layer mask) and paint over the area that you do not want filtered with a soft, black brush. Job done.

Trinidad faces and JSF faces not optimized for android web-browser.

We are developing Mobile based application using Oracle ADF Mobile (Jdev R1). Trinidad Faces and JSF faces are rendering optimized on all smart phones (i.e. iPhone, Blackberry and windows) except Android (linuxwebkit) web browser. On Android web-browser page rendering as render in desktop browser.
any idea please?
thanks
yousuf

Hi,
copying the answer I provided on the Stack Overflow forum to the same question:
Apparently you are correct and the ADF Mobile developer guide for 11g R1 doesn't mention Android as a target platform: http://docs.oracle.com/cd/E23943_01/web.1111/e10140/toc.htm
However, JDeveloper 11g R2 does : http://docs.oracle.com/cd/E26098_01/web.1112/e16178/toc.htm
Just search for "Android" and you see what I mean. As you mention the base technology is Apache MyFaces Trinidad and the version of Trinidad thus determines the support for mobile devices.
Apparently JDeveloper 11g R2 uses the Trinidad libraries (JSF 2) that support the Android platform while JDeveloper 11g R1 does not.
Given that Trinidad 1.2 supports Android (though it might not have been tested as mentioned here: http://myfaces.apache.org/trinidad/devguide/mobile.html) you should be able to create your own skin for Android as documented here: http://myfaces.apache.org/trinidad/devguide/mobileSkinning.html
The RequestContext object in Trinidad returns the calling agent and you may want to check first if this returns Android. If it does then creating and applying a skin is easy to do.
