jsf-2

问题 I'm building a WebApp in jsf 2.0 and it's about storing information and displaying it on the screen. so I've put in some "http://java.sun.com/jsf/html" dataTables to disply some lists. My Java code returns a List and then displays them on screen. but now I have to Sort the columns alphabetically. I believe there's no built in way of doing this, so i'm goign to have to look elsewhere for the task. I came across This dataTables example, it's pretty awesome but I think I can't give it a List and

问题 I'm using JSF 2.0 and EJB 3.1 in the Glassfish v3 app server. And I'm facing actually the follwing problem: In a MenagedBean with RequestScope I want to access a session object (an EJB with @Stateful) which should store some session relevant information as the seleced category, the seleced page (with a datatable paginator for each category), etc. - nothing special I think. The first time a category is selected, the datatable is created and displayed. Allright so far. Now, if an item (row) is

问题 Where can i find a jsf-impl for my jsf 2 webapp ? In maven's repo i got the 1.2 version. In the http://download.java.net/maven/2/javax/faces/, i can see only the jsf-api, but no jsf-impl Im currently using tomcat 7, and experimenting with primefaces. Thank you ! UPDATE I've been able to get both the api and the impl using this, but im still not sure which impl i should really use : <dependency> <groupId>com.sun.faces</groupId> <artifactId>jsf-api</artifactId> <version>2.0.3</version> <scope

问题 Always when I deploy my project (jsf) I get the following error on my JBoss AS7. On JBoss 6 everything worked fine. What can be reasons for that error message? Do you have any idea how I can solve that?

问题 So, I have tried to implement the methods from Anthony/BalusC in this question: How to get selected row index in JSF datatable? but to no avail. I also went through @BalusC's "Using datatables" article (which is wonderful as always) but that was written for JSF1.2 and the 2.0 article doesn't really address getting the selected row data. When a user clicks the "Add to my favorites" button, the selected row is not getting passed to the backing bean, the navigation case is not being followed,

问题 I am using primefaces autocomplete component with pojos and which is filled from a database table with huge number of rows. When I select value from database which contains millions of entries ( SELECT synonym FROM synonyms WHERE synonym like '%:query%' ) it takes a very long time to find the word on autocomplete because of huge database entries on my table and it will be bigger in future. Is there any suggestions on making autocomplete acting fast. 回答1: Limiting the number of rows is a great

问题 I have a form with tree buttons on in. One of them is the "Cancel" button that goes back to the previous page. The problem is there is any validation issue, like a mandatory field not submited, the styling of the field is not reset when I go back to the form. This is a simplified structure of the xhtml: <panel id="horizontal"> <form id="filterVipLoungeForm"> </form> <form id="frmAddPax"> <form id="frmAccessType"> </form> </form> <panelGrid> <commandButton value="agregar" /> <commandButton
