I have a selectonemenu in my jsf page and i need to navigate to different pages based on the value selected in the selectonemenu.
I tried two approaches:
2. Second approach is to navigate to the required page using response.sendRedirect in the valueChangeListener for the selectonemenu. With this approach, the control comes back to the initial page and no navigation happens.
How are you defending/explaining the navigation concepts of AJAX in your book?
If users create a bookmark in their browser, they may not get the same view back when they follow the bookmark at some later point in time. We all know that navigation does not work properly with ajax, since the unit of navigation is different from the unit of view.
Hi, I'm planning to take the exam in the near future. I've been watching this topic and got interested to know what are the expectations of the interviewers. Please send me ur questions to firstname.lastname@example.org [ July 14, 2005: Message edited by: anitha lingam ]
In some other part of the application i need the same output but i do not want to use the existing tag due to some issues.
Here is what i need: I have written a class to output the required details. But basically i want to just call the doStartTag() of my existing taghandler so that i can reuse the code. When i do this, i get the following exception javax.servlet.jsp.JspException: Cannot find bean EMPLOYEE in any scope - Here EMPLOYEE is the name of the textbox and i am setting this value using the setName().
Thanks for your reply. There are high chances of using JDO in our project. So would like to know more about JDO. Moreover i learnt that JDO is a standard and it is portable while Hibernate is not. What are the features available in Hibernate that is not available in JDO or vice versa. Is it that developers started using Hibernate that they do not want to switch to JDO.
I'm new to O/R Mappers. I would like to know more about JDO, Hibernate, Castor. Which is the best option? What are the advantages and disadvantages of each of these. How each of these differ from each other? What are the other alternatives?
Hi, I have an integer form field. In my ActionForm I extend the ValidatorForm and i'm trying to Validate that field. My validation.xml for that integer field looks like this <field property="vcoord" depends="required,integer"> <arg0 key="vcoord"/> </field> When i enter my jsp page, this field is automatically set to 0. Even when i remove the 0 and perform the operation , validation doesn't happen. Instead the field is set back to 0. The same problem occurs when i try to enter a string to the integer field and validate it. i.e..it doesn't validate telling that it is not an integer instead the value is set back to 0. Can anybody help?? Thanks in advance.
