backing-beans

I am using Primefaces 3.1.1 charts in my application, there is no problem generating charts in JSF page, but I'm trying to find out if it's possible to generate image (png or jpeg) for the charts so that I can insert these images into an Excel file (Apache POI) in java. I know the latest Primefaces version 3.4.1 has an Export Chart feature, but the generated image only occurs at the client side (it's jqPlot). But I need it on the server side. Currently we are using jFreeChart in the backing bean for this purpose, so the charts in browser looked very different from the charts in Excel. We are

I'm mostly working with legacy code in a JSF based project and there are lots of quite long classes and methods in backing beans. This is constantly bugging me but when I look for what can be done, most of the time all I can come up is to divide a long method to n small methods. Which gives you still a very long class and sometimes harder to read too. So what do you do to keep your backing beans short and concise? Or do you keep one big backing bean for one page? Are there any best-practices? I assume this is not directly related to jsf but to any model where you are 'backing' up your view

There is an error each time a button calls an action from the backing-bean. Only applies to beans with a view scope and I haven't found a way to fix it without regression over other modules in the code.

I have a form with a variable number of input elements, like this: <ui:repeat var="_lang" value="#{myBean.languages}"> <h:inputTextarea value="${_lang.title}" id="theTitle" /> <h:messages for="theTitle"/> </ui:repeat> When a certain method in the backing bean is triggered, I want to add a message to, say, the second iteration of the ui:repeat , but not the other ones. I've seen different variations of this question around here , and all problems appear to be due to the ui:repeat 's iterations not being available in the JSF component tree. What I have tried so far: Bind the h:inputTextarea s to

I've looked at a few resources for JSF and facelets, but don't understand a few configuration points. What's the distinction between: <url-pattern>/faces/*</url-pattern> and: <url-pattern>*.jsf</url-pattern> While I understand it's possible to have several url-pattern elements, unless .jsf pages are explicitly being used, there's no actual need for this mapping, correct? If only faces templates and clients are being used, then it's extraneous? Furthermore, if the facelet template and client are inside WEB-INF , how are they accessed? With the latest releases for JSF and Facelets, there seems
