jsf login times out

由 青春壹個敷衍的年華 提交于 2020-01-29 08:43:25
问题 Ok simple question. I have a JSF application, containing a login page. The problem is if the user loads the login page, leaves it for a while, then tries to login the session expires and a ViewExpiredException is thrown. I could redirect back to the login when this happens, but that isn't very smooth. How can I allow this flow to properly login without an additional attempt? 回答1: Update As of Mojarra 2.1.19 / 2.2.0 you can now set the transient attribute of the <f:view> to true: <f:view

When submitting the form I want to skip(or ignore) the required validation check and still invoke the application. I do want to do the form data validation and show the errors based on some condition. Basically I want to skip the validations and invoke the application when the form is submitted using an ajax

问题 My application needs to implement dynamic images, where a browse can get served a JPG or PNG out of my data base. I have been reading this thread and am not getting very far in learning from it. Can someone provide a link to a tutorial about how to implement a ResourceHandler. Having looked through all the books Amazon offers on JSF 2.0, none of them seem to cover this topic. Thanks in advance. UPDATE: This question is withdrawn since I took a different path to the solution, which was simply
