Wondering if there's a configuration approach that can be taken with Hybris to achieve the suppression of version number being disclosed in error pages which have no explicit definition in an extensions web.xml
Can this be done using any of the OOTB properties files?
Thanks
You can configure an error page in your storefronts web.xml. Find it here:
/mystorefront/web/webroot/WEB-INF/web.xml
Somewhere in that file there is a tag "error-page". It might look like this:
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/WEB-INF/path/to/serverError.jsp</location>
</error-page>
<error-page>
<error-code>500</error-code>
<location>/WEB-INF/path/to/serverError.jsp</location>
</error-page>
Keep in mind, that in case of an error you are restrained in the functions you can use. So keep these error pages as simple as possible.
You can implement custom error pages to prevent such unexpected behavior. Mosty it handled at Apache Web Server. Like this, this.
However, as #Johannes answered, you can also configure in Hybris using error-page tag of yourstorefront's web.xml
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/WEB-INF/pages/error/serverError.jsp</location>
</error-page>
<error-page>
<error-code>java.lang.Exception</error-code>
<location>/WEB-INF/pages/error/serverError.jsp</location>
</error-page>
It's not just on the error page but also in headers. See here:

I am unable to set a default page that loads in the browser when I start a Java EE project using Tomcat 8.0 from Eclipse.
I am trying to learn JSF, so I followed this tutorial
Everything works fine, but I can only see the created pages when I right click on the login.xhtml or welcome.xhtml file and choose "Run As/Run on Server".
So far, all the other web applications I have created loaded default page when I started the entire project. The default behavior is to load index.html page (or maybe index.jsp if there is some). So I added index.html and index.xhtml pages into my WEB-INF folder in the project, hoping that at least one of them will be shown. However, nothing happens. The browser always shows just the page on localhost:8080/JSFFaceletsTutorial/ URL, but the page is white clean, not even an error message. I think I have been getting error 404 in the process of solving this issue along the way, however, I am no longer able to reproduce this error and I don't remember what caused it.
I found that it's possible to change the default starting page
However, it doesn't work for me either. Regardless if I edit the web.xml file or not, I am getting the same result.
What is even more puzzling, is that when I tried to change the web browser: "Window/Web Browser/..." it acted for a while differently in the external web browsers than in the internal Eclipse web browser. The internal had always blank page - but the external web browsers once managed to show the index.html page - but it was some outdated version. Despite I made absolutely sure that I edited it, saved the changes, restarted the server... and still, it showed me the outdated version of the page.
And even in this case, it still ignored the changes made in the web.xml file.
But when I am trying it now, it again shows blank white page in all browsers. I am not aware of any change I made except for editing web.xml file...
My guess is that the problem is in the JSF technology I don't fully grasp yet. It's because when I choose to run the login.xhtml and welcome.xhtml pages using right click "Run As/Run on Server", the URL of those pages are on localhost:8080: with path /JSFFaceletsTutorial/faces/login.xhtml and /JSFFaceletsTutorial/faces/welcome.xhtml. That is weird, because I don't have any directory "faces" in my project.
Typing all possible permutations of:
<welcome-file-list>
<welcome-file>faces/index.html</welcome-file>
<welcome-file>faces/index.xhtm</welcome-file>
</welcome-file-list>
in the web.xml didn't help either. It didn't help when I typed the full address there either.
Here are warnings I am getting in the console (I skipped the INFO log entries):
"Dec 19, 2014 9:39:55 AM org.apache.tomcat.util.digester.SetPropertiesRule begin
WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:JSFFaceletsTutorial' did not find a matching property.

I am not sure this is helpful though.
I am out of ideas now.
First of all, the <welcome-file> does not represent the path to the "default home page". It represents the filename of the physical file contained in the folder which you'd like to serve up as default file when a folder like /, /foo/, /foo/bar/, etc is requested.
So, in JSF 2.x flavor, that would basically be:
<welcome-file-list>
<welcome-file>index.xhtml</welcome-file>
</welcome-file-list>
This way, if the enduser requests / and you have /index.xhtml, then it will be served. Or, if the enduser requests /foo and you have /foo/index.xhtml, then it will be served, etc. If there is no such file, then a 404 error will be returned.
Now, you appear to have mapped your FacesServlet on a prefix <url-pattern> of /faces/*. This is a leftover from JSF 1.0/1.1 ages and really not recommended these days. Perhaps you were reading an outdated tutorial targeted at JSF 1.x, or a poorly maintained tutorial which was originally written for JSF 1.x and then uncarefully updated for JSF 2.x instead of rewritten from scratch.
That tutorial did also not seem to have explained you some servlet basics. Namely, in order to get JSF components in the XHTML page to run and generate some HTML output, the FacesServlet has to be invoked when the XHTML page is being requested. When you request the XHTML page like so /index.xhtml, while the FacesServlet is being mapped on /faces/*, then it won't be invoked. The browser would then retrieve the raw unparsed JSF source code instead of the generated HTML output. You can see it by rightclick, View Source in webbrowser. You should have requested the page like so /faces/index.xhtml so that the FacesServlet can run and produce HTML output which the browser can understand and present.
That only doesn't go well together with welcome files. This totally explains why you get a "clean white" (blank) page when using index.xhtml as welcome file (some inferior webbrowsers like IE would confusingly prompt a download dialog because of missing/wrong content type on the response containing raw XHTML source code). The FacesServlet was simply not being invoked. Just get rid of the old fashioned /faces/* URL pattern and use the JSF 2.x minded *.xhtml URL pattern instead.
<servlet-mapping>
<servlet-name>facesServlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
This way the welcome files should work and you can just open JSF pages by directly requesting its physical URL without hassling with virtual URLs. This was not possible in JSF 1.x because it would let the FacesServlet run in an infinite loop calling itself and cause a stack overflow.

As to those warnings, they are unrelated but quite googlable.
i think this will work
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.xyz.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.xyz.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<welcome-file-list>
<welcome-file>/main/login.xhtml</welcome-file>
</welcome-file-list>
<!-- <servlet>

</servlet>
<servlet-mapping>
<servlet-name>login</servlet-name>
<url-pattern>/login</url-pattern>
</servlet-mapping> -->
</web-app>
You can set a default page in the web.xml file to have the facesServlet invoked in JSF in 2 ways:
<web-app xmlns="http://xmlns.xyz.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.xyz.org/xml/ns/javaee http://xmlns.xyz.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<servlet>
<servlet-name>facesServlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>facesServlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.xhtml</welcome-file>
</welcome-file-list>
</web-app>
or invoke the facesServlet directly from the welcome file like this:
<web-app xmlns="http://xmlns.xyz.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.xyz.org/xml/ns/javaee http://xmlns.xyz.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<welcome-file-list>
<welcome-file>faces/index.xhtml</welcome-file>
</welcome-file-list>
</web-app>
I hope it helps somebody!
I am getting below error.
FAIL - Application at context path /sampleJSF could not be started
I want to change my welcome file location. I have a index.jsp page at WEB-INF/pages/index.jsp. How can I modify servlet mapping and welcome file list to achive this?
Here is my servlet-mapping and welcome-file-list from web.xml.
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>WEB-INF/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>WEB-INF/pages/index.jsp</welcome-file>
</welcome-file-list>
It look like that you misunderstood the purpose of both the welcome file setting and the /WEB-INF folder.
The welcome file must represent the name of the file which the server should serve from the current folder when a folder is been requested instead of a file in URL. E.g. /, /foo/, /bar/, etc. So, when you set it to index.jsp, then it will serve /index.jsp when / is requested, and /foo/index.jsp when /foo/ is requested, etc.
The /WEB-INF folder is for files which shouldn't be independently publicly accessible. For example, include files, template files, error files, tag files, configuration files, etcetera. Mapping the Faces Servlet on /WEB-INF makes no utter sense as the servlet container already restricts direct (public) access to /WEB-INF folder when the enduser purposefully enters the /WEB-INF folder in the URL.
Undo all those changes you made on the sample web application. They make simply no sense. Whatever functional requirement you had in mind for which you incorrectly thought that this is the right solution must be solved differently.
Unrelated to the concrete problem, it look like that you're just getting started with JSF, but do you know that JSP is deprecated since JSF 2.0 in 2009? Are you absolutely positive that you're learning JSF based on the right and up to date resources? I strongly recommend to do so, or you will end up having confusion headache and code disaster. Start at our JSF wiki page.
When I request /personal/faces/public/login.xhtml, then it works fine, but when I request /personal/public/login.xhtml without /faces I obtain the raw source code of the page.
I would like to avoid that people could see the source code of the page. How can I achieve this?
This is happening because you've specified /faces/* in your FacesServlet configuration in the web.xml. As a result, any file requested that does not match the specified url pattern will be served as a regular file with a GET request
Change that config to the following to ensure all JSF related requests go through the FacesServlet:
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
This ensures all files with .xhtml extension will be processed before returning to the client.
While the above solution may solve the immediate problem, what you're experiencing points to a deeper security issue. It indicates that anyone with a browser can request and download artifacts from your web application deployment and possibly other parts of your filesystem. This is a security hole you will need to look into. The options vary depending on your App server
I am trying to redirect my user to the login page when the session expires. I followed the instructions on this link How to handle session expiration and ViewExpiredException in JSF 2? and it works, except for the fact that it redirects me to a non existing page.
In my application root, I have a login.xhtml page. So in my web.xml I have this:
<error-page>
<exception-type>javax.faces.application.ViewExpiredException</exception-type>
<location>/login.xhtml</location>
</error-page>
But while using the application I am at localhost/sample/user/create.sm when the session expires, it redirects me to localhost/sample/user/login.xhtml, while I expected to be redirected to localhost/sample/login.sm. How should I make the correct configuration?
I am using jboss 6.1 and mojarra 2.1.7
Thanks
The <location> has to match the FacesServlet mapping. You seem to have mapped it on *.sm instead of *.xhtml. In that case, change /login.xhtml to /login.sm.
I've got a JSF 2 application running on glassfish and have just installed the caucho
quercus PHP implementation. With just a little configuration I can successfully serve
.php files from the server:
<servlet>
<servlet-name>Quercus Servlet</servlet-name>
<servlet-class>com.caucho.quercus.servlet.QuercusServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Quercus Servlet</servlet-name>
<url-pattern>*.php</url-pattern>
</servlet-mapping>
What I'm not able to do is use h:link to navigate to a page that doesn't use the
default suffix (.xhtml). So when I have:
<h:link outcome="/hello.php"/>
I just get a WARNING: JSF1090: Navigation case not resolved for component j_idt48 in the server log (when the page is loaded), and no amount of fiddling with leading / seems to help. Is there a way to get h:link to work in this way or should I just use h:outputLink?
Thanks.
<h:link> is for JSF navigation cases only, and thus indeed can't be used to navigate to other kind of resources, even when those are served by Servlets in the same application (like *.php in this case).
As you already suggested yourself, just use <h:outputLink>.
