Jsf web application has to be restarted everytime a broken pipe exception

Hi,
My jsf web application using tomcat is experiencing a sql exception "java.sql.SQLException: System or internal error java.net.SocketException: Broken pipe" when it tries to connect to database.
Everytime this exception happens I have to restart the application and the application runs fine then.
Is there a way to handle this exception that we don't have to restart the application.

It depends....
How do you have (where) the connection, how you obtain them, etc?

Creating a JSF Web application from scratch.

hi,
i have created a JSF web application, but not from scratch i had to use a jsf example included in the final specification of the JSF download, as a template to create my own application, by deleting and editing the example files with my own.
i tried to do it from scratch including all the settings, parameters and files that should be in place, but i sill get an error when starting the app in tomcat.
Unfortunately i dont have the error listing anymore since i have got around the problem through alternate path. however i do remember that it came with cannot find FacesServlet, or something to do with the FacesServlet.
if anyone could shed some light on this it would be really great because it so frustrating.
many thanks.
dharam

cannot find FacesServlet, or something to do with the FacesServlet.It might appear not because you have a wrong project structure, but because you point to the entry jsp file directly without using the servlet mapping in your URL. Check this first.

Access an Application Module Client Interface in a JSF Web Application

How to Access an Application Module Client Interface in a JSF Web Application
I use this code but class ValueBinding is deprecated in JDeveloper11g
FacesContext fc=FacesContext.getCurrentInstance();
ValueBinding vb=fc.getApplication().createValueBinding("#{data}");
BindingContext bc=(BindingContext)vb.getValue(fc);
DCDataControl dc=bc.findDataControl("SRServiceDataControl");
ApplicationModule am=(ApplicationModule)dc.getDataProvider();

user581394,
JDeveloper 11 and the introduction of ADF Faces RC introduces a new dependency, which is JSF 1.2. The createValueBinding on the FacesContext object is deprecated in JSF 1.2. To resolve an expression in JSF 1.2 use the following method or something similar.
    public static Object resolveExpression(String expression) {
        FacesContext facesContext = getFacesContext();
        Application app = facesContext.getApplication();
        ExpressionFactory elFactory = app.getExpressionFactory();
        ELContext elContext = facesContext.getELContext();
        ValueExpression valueExp =
            elFactory.createValueExpression(elContext, expression,
                                            Object.class);
        return valueExp.getValue(elContext);
    }--RiC

Does any body have any design patterns of JSF Web Application Developping?

Can any one answer me some questions?
#1.I am an amatuar of people who develop Web Application.For some reason,We choose the JSF to develop our item.through some introduction,I know the UI component of JSF is resided in Server side,is it right?but I am a little confused that:if there are many users who are exploring our jsf website.(to simplify my question,image I had just one web page and just one button)How many UI components(buttons) will be there?How it(they?) works?
#2.Does any body have the success experience (for example design pattern)to develop web applications?if We just concern about the Add,Delete,Modify,Query operations of some data.
I just do my job according to my feeling.
I will give every page a pagebean(backing bean),and I am not sure how to combine the business data with the pagebean.some one suggested that I should use delegate pattern to separate my business log and page logic.But I am still confused by following things:
#2.1 does JSF have the same ability to help us construct the model dialog just like swing to
help us control the operation flow?
#2.2 If there is not,Does the following way work?I put every tabledata's property as corresponed component.if user choosed the row in the table,My Listener will syncronize the row data to the components.But
#2.2.1 if JSF has the components according to the web users' number,how can My Listener tell which component should be update?Should I maintain the map?
#2.2.2 If the problem I imaged above is false,Does any body can tell me how to custom the ListDataModel,so I can use it like Swing?because now I can just use some view data to insert into ListDataModel,but after some selection operation,my business object must be find according to the selected data,it is not an interesting job!
I am waiting for your advice!

Ok I'll try to explain Step by step please correct me if I make any mistake because I have not played much with shared variables.
To create a shared variable to an RT target go to the target if tou have already otherwise add an RT target by right clicking the Project>>Add targets and Devices
Then in the target Right clikc and select the variable as shown below.
Then once the Shared variable settings window opens Enter a variable name and then Select the type "Network Published"
In the right side you can select the data type for the shared variable and even you can choose your custome controls.
After selecting the data type go for the Network and select buffering if required else leave it if you are planning to use the variable just for display purpose.
Then you can enable the RT FIFO if required (Not able to explain how it works and why it is used).
Then after completing the Shared variable setup you can access the variable in the VI in both the Host and the RT.
You can bind the variable to a control so that if any data from the RT is coming you can read the data from that control.
Once you have placed your shared variable in the BD you can change the access typr to read or write depending on your need.
This might not explain the complete shared variable concept but I believe that this would defenelty give you a kick off to start using the shared variable. Please correct or add more comments if anybody know better.
Good luck.
The best solution is the one you find it by yourself

Ll / seeking FREE open source JSP / JSF Web application Tomcat/5.5.15

hi all,
We have a need to set-up a web site for a community based (non profit organisation) football / soccer) club.
The web hosting machine is based on JSP / JSF running on Apache Tomcat/5.5.15 & Sun Microsystems Inc. VM 1.5.0_06-b05.
OS is Windows 2003 V 5.2
The database backend is based on MySQL, mysql-essential-5.0.18-win32.
We need to add content related to:
a) Players contact details;
b) Teams;
c) Match reports;
d) News;
... and other dynamic content
We are looking for an out-of-the box FREE open source Web application we can deploy on the web hosting machine.
Any suggestions will be appreciated.
Thanks
Trajano

I haven't tried ICEFaces or JBoss seam or Apache MyFaces, so I can't really compare them.
ICEFaces appears to be a nice framework/tool from looking at their site, even though it's open source I think one has to pay for support, you might want to take that into consideration while making your decision.
Apache MyFaces, is fully community driven - so you get free support from the community.
I don't know about JBoss seam.

Intention of JSF (web applications or web sites?)

Hi,
I want to write a web application that has a similar look and feel to todays desktop applications. Thus I don't need a typical web site look (title on the top, navigation bar etc.) but a more desktop look (a menu bar on the top, a status bar on the bottom etc.)
Although I like JSF I am not sure, if this framework is the best for this job. Thus I wanted to ask, if you can tell me the intention of JSF:
Is it to build web sites or is it also to build web applications without the typical web site look and feel? With JSF both is possible of course. And with the adequat JavaScript library on the client side it looks very nice (e.g. ExtJS).
But was this one of the intentions of JSF? Or was it primarily to build usual web sites with a page flow etc.? And maybe another framework is better for what I am going to do?
I only don't want to use a JSF for something it has not been made for.
Greetings
Mike

I don't see what the point is in making a distinction between web sites and web apps. Are you trying highlight the difference between say Apache vs. JBoss?I'm not sure what you mean by "the difference between say Apache vs. JBoss" but here's what I meant. When I think a web site, I think of a site where the interaction tends to be more reading, clicking from page to the next, etc., like, for example a news site. With a web app, I tend to think of statefulness, business processes, etc, like an online accounting system, content management system, etc. The distinction is probably pretty academic, though...
Well you need to decide if you're making a simple web site that serves static content or i fyou're making an application with a GUI. There's a big difference.Exactly.
For a desktop-like application, I say web browsers in general are a bad choice. I'd use Web Start if possible and write a GUI. In any case, Hehe. That's a completely different (though very valid argument(
AJAX is the last thing I'd use (now you're writing HTML, XML, AJAX, Java, etc..). Echo2 provides 1 single API rather than hacking several. Flex, while I haven't used much, seems to also provide a much cleaner solution. Fair enough, and that's not an uncommon opinion. I'm probably somewhere in the middle, but, for what I've been asked to do since the web 2.0 hype started, Ajax has been sufficient. I'm not Echo2 expert, but isn't that just an HTML/JS interface with a Java backend with Ajaxy operations? For really, really complex and dynamic UIs Flex (or JavaFX :) might be more appropriate.
Again, I haven't used JSF so I can't say much about it. But I see lots of projects all the time and JSF seems to be slow for adoption so far. Just my personal experience.Hmm. I've used it for about three years now, fwiw, and really, really like it. Which probably isn't worth much. I will admit, though, that JSF isn't always the right tool (thus the discussion here). As far as adoption goes, it seems to be growing much faster than the other frameworks out there, but I may have tinted glasses... ;)

In a JSF Web Application

Is there anyway in the .JSP, Javascript or Backing Bean to iterate over all the files in a directory on the server?
I want to iterate over all the files in my images directory
development
http://localhost:8080/<app name>/images
production
http://<domain>/images
Something like the like what Alex Wong is doing here... but as I say in a Web Application
http://www.javapractices.com/Topic68.cjp

The why is that I would like to be able to put up some image files, then when the user clicks to go to a certain page, that directory would be read and the thumbnails of the images in that directory would be displayed. I'm doing this to a degree currently in a javascript, accessing the directory via www.<domain>/images, but in the current case, the names of the files are already known.
That's why I need to be able to iterate over any files that are in the directory, not just known files.

JSF - Web Application Fast

Hai Respected Friend
Sorry for posting this doubt in this site because this not a JSF related Question.
I have some doubt regrading Web Page working fast . Actually some website is working vary fast while some one is not . please let me know normally web site working speed based on what
1) Java Technology , Server (Application , Webserver). or
2) Our client ,m/c Hardware requirement or Server m/c Hardware requirement include RAM speed , Processor Speed. or
3) Data base server or
4) Net Connection service Provider speed .
Advance Thanks for your later Reply .

JSF Web Application - endless redirecting loop

I've created a simple JSF WebApplication, just one page, one static text. When I deploy it to the bundled server, everything is OK. When I deploy it to a remote server, that I have access to (Sun Java System Application Server Enterprise Edition 8.1_02), and I browse to its URL (http://server:port//Webapplication), the browser shows me an error. IE just displays Page cannot be displayed error, Firefox tells me, that the app. ended up in a redirection loop.
When I browse to /Webapplication/faces/Page1.jsp, everything is ok.
What can be wrong?

Hello
We are looking at doing the same thing (iviews in Sharepoint)
Any luck in solving the problem ?
thank you

Db /listener down , application has to be restarted

Just want to clear , when db / listener went down, application also goes down, when db / listener are started , application dont start auto, may be if its programmed like that otherwise it need to be started manually...right

Applications console are different from database consoles.
If the listener is down application would be down but the processes running the application are still up.
So once the listener is up the application should be up automatically.

Dynamic class reloading in modular web application

Hi.
My web application has these requirements:
A. Functional modularization (like plug-ins). Modules will be simple jars containing application logic classes: dto beans, business logic services, dao (jpa), framework stuff (Struts2), etc...
B. At runtime and without restarting the application "class loading" must be aware of classes inside new, changed and removed modules.
C. Some of these jars will be outside the web application folder (WEB-INF/lib), possibly outside the container itself too.
My question:
1. Can I achieve all or some of my requirements with a Java web application?
2. How should I manage the modules?
3. Do I need some special web container feature (maybe osgi)?
4. Can I use a custom class loader in my application?
The architecture objectives are:
I. Provide scalability.
II. Efficient development process (independent deployment and no application restart required).
III. Better production support (no application restart required for changes).
More on the architecture:
a). Functional scalability, meaning this that my application may functionally grow up to an indeterminate number of small functional modules.
b). Modules will be developed, deployed and maintained independently so the application discovers and loads classes on demand.
c). Avoid a big .war file containing all the small modules because a small change in one module would involves deploying all the other modules (possibly hundreds o even thousands of them) and restarting the application.
d). Above point involves dynamic class reloading.
I guess this is addressed by OSGI (looks like heavy to deal with), Jigsaw (still under development) and maybe others. I think the key point is the class loader. I will develop a custom class loader but maybe you have some advice for me before starting to develop.
Thanks and regards.

Classes maintained by the container should not be loaded by an application. You want the container to read those classes and react accordingly. Most of those classes are read when the container starts up a container restart will be required. Trying to leverage another container within a container does not sound like it will be worth (if you can get it to work).
Perhaps you should state the problem that you are trying to solve with these modules so that others may suggest more feasible solutions to achieve your target goals.

Web Application and Java Application

Hello,
I have a standalone Java application and a web application (JSP/Servlets) that I would like integrate. The standalone app. should send some information to my web app (which is not a problem), but then the user can be at this web app. for a while and then once he sees something he likes here, he can select it which should take him BACK to the standalone application. My question is whether something like this is possible?
If so, then how do i do it.
Also the web app and the standalone app run to 2 separate machines and 2 different JVM's.
Any kind of help will be great.
Thanks

Well let me describe the scenario in detail
We have a standalone java application that is good to search for data across an enterprise database. We also have another application which is web based and uses jsp's and servlets and is good for displaying data in different ways, let's say different kind of graps. Now the user will typically search for something using the standalone application and once he finds what he is looking for, then he might say that he wants to graph the selected data using this web application. Now this part is not too difficult as the standalone app can simply POST the selected information to the web app and the web app can then plot the graph. However, the tricky part is that this web application has the capability to allow the user to select let's say a bar and then get additional info. on that bar. Now to get this additional info. the web app. must contact the standalone app and tell it what bar was selected to get the additional info.
so my concern is how does the web app contact the standalone app. or even KNOW about this web app. Also, RMI is pretty flaky and i would much rather use web services to accomplish it. If that is the only way to go that is.
Hope that helps.

My Sites error - 403 and "We're almost ready!" plaguing web application

On an in-house managed farm, a My Site web application has been created per the instructions provided from
Microsoft. The web application uses the managed path "personal" at the root of
http://mysites. The initial "We're almost ready!" screen when accessing a social feature like
Newsfeed was anticipated. However, in attempting to update the My Site content (i.e. profile information, newsfeed settings), the user is presented with a 403 Forbidden page - "The website declined to show this page".

Troubleshooting efforts so far in addition to the sources quoted above:

Creating a special permission policy for the web application to allow "Everyone" to create subsites
Checking SQL rights for SA's and their respective DB's
Started IIS application pool "SecurityTokenServiceApplicationPool" (it was stopped initially)
ANY help in further troubleshooting this issue would be greatly appreciated. I have already re-created the web application multiple times with the same results each time. Thank you.
Eric

I re-created the web application again. What's the definition of insanity? Doing the same thing over and over and expecting a different result? Well, in this case I actually did get a different result. At least this time there
wasn't a 403 error, but a 404! Success!
In any case, I used a load balancer for this farm and re-mapped the bindings in IIS to point to that IP. Lo and behold, we have lift off! Everything is working, even the social features. All it took was me talking to myself in a forum and
doing repetitive tasks expecting different results... oh, hang on, there's a nice gentleman in a white coat here to take me some place nice. Thank you!

What is the correct way to set a web application to use HTTP or HTTPS?

In the past I've always created an HTTP web application as the default zone. Then extended the web app, creating a new IIS website on port 443 and enabled SSL. This seems to have worked fine, but I recently read an article stating that it is not good to
extend a web app unless absolutely necessary. So can someone tell me what the proper way is to configure a single web application to work with HTTP and HTTPS?

Extending the web application to support both HTTP and HTTPS is a perfectly good method and in fact is the only way to have a web application support both so what you've done is fine.
If the web application will only use HTTPS, you can set this up when you first create the web application. Specify port 443 and the SSL option (and ensure the URL has an https://) when creating the web application. You'll need to install the certificate
in IIS once the web application has been created.
