How to detect a field value change in a JSF 2.0 page

由 时光怂恿深爱的人放手 提交于 2019-12-21 17:05:30
问题 I am using JSF 2.0 to develop a pretty big and complex page which contains numerous fields. Thre would be quit command button at the buttom of the page and when ever user selects the quit option I need to detect whether user has entered any value on one of the fields of the page. I am using the null check of each field values in the backing bean to do that now, but that's a very tedious and repeative job. I was wondering is there any smart solution for that ?? Any help will be highly

When is session created during JSF login?

由 落花浮王杯 提交于 2019-12-21 13:08:12
问题 In JSF, it seems that sessions are created before a successful login. i.e. simply requesting the login page causes a new session to be created. It seems very wasteful (and vulnerable to DDoS attacks) to create a session for each request received, rather than each successfully logged in user. The code below is pretty generic, but shows the kind of simple scenario I'm referring to. index.xhtml: <html> <body> <h:form id="login"> <h:outputLabel for="username">Username</h:outputLabel> <p:inputText

Multiple validators for one input

由 让人想犯罪 __ 提交于 2019-12-21 12:43:28
问题 Is it possible to have multiple validators for one input in JSF 2.0? For example, say that I will write a username and the username must have 8 characters. And if OK, then check if the username does not exist in the database. <ice:inputText id="username" value="#{createClient.username}" maxlength="15"> <-- something like this --> <f:validator validatorId="usernameValidator" validatorId="usernameExistValidator" /> </ice:inputText> <ice:message for="username" /> 回答1: This is absolutely possible

JSF Adoption and Popularity

由 ぃ、小莉子 提交于 2019-12-21 09:26:55
问题 Just a general question, open for discussion... I'm very much liking JSF so far, I'm new to it, but I prefer it to Struts. From a professionals standpoint, do you see a strong future for JSF ? Is it worth an investment as a young programmer to learn JSF 2.0 over Struts or another similar framework ? Should I stick to regular JSP ? Is Ajax really simpler through JQuery than JSF ? I like new technologies and I like what I see so far from JSF but I want to be practical as well, and a lot Google

Couldn't access FacesContext.getCurrentInstance() from Self Spawned Thread

问题 Couldn't get "FacesContext.getCurrentInstance()" in self spawned thread. Required to update the components dynamically based on a back-end process. Achieved the same by creating a thread for monitor the process and call back the component updation along with p:poll. However, seems "FacesContext.getCurrentInstance()" is not available for the new thread. Just getting NPE while calling any utility methods that relies with FacesContext.getCurrentInstance() from the newly spawned thread. Is there
