Hi Experts

As every body knows Exception is a super class of several checked and unchecked exceptions.But how can conclude i should not catch exceptions if it is not generating in the code block? Obviously unchecked need not want any discuss , because it crystal clear. But in case of checked exceptions some of them allow us to include it even it not generating and some of them in other way. How to make a conclusion?

Java in General

I have some doubt in exception handling.
As we know Exception,FileNotFoundException and IOException are all checked exceptions. right?
But in the following code first exception catching not display any compiler error but other two. why?

1.

2.

3.

I imported java.io package in the source. But i am confused by the behaviour that no compiler error for catching Exception class even if it is not generating any such exception in code block.
Any comments??

Hi Experts

I have an issue with validator for password field.I am using struts 1.3 and enabled validator in struts-config.xml file.Below giving the files which i used.

1.ExampleForm.jsp

2.staticjavascript.jsp

3.Struts-config.xml

4.validation.xml

5.ExampleFormAction.java

6.ExampleForm.java

Issue: My issue is with password field.Whenever i validate password field for mask value, even though the error is detecting it is not showing just like required validation. It is rentering in the ExampleForm.jsp through the <html:errors/>. I changed the password field to <html:text property="password"/> it worked as i expected. Any one have any idea?

struts 1.3 Interactive form

Thanks Ess

I resolved it using LazyDynaBean.i think LazyDynaBean is the only solution for crating ineractive formm in struts 1.3. Also i used pure input elements from javascript,because sturuts based is not possible.Any way with javascripts struts elements are not flexible.

Thanks.

struts 1.3 Interactive form

Hi Experts

I fedup with struts in case of creating interactive forms. I think it has lot problems to work with it. It is not possible to add dynamically one more element and taking the value from java script.

i tried like this from java script..

document.forms['registerForm'].elements['boardname[1]'].value;

here boardname is an indexed property of registerForm(ActionForm).

But i am getting boarname[1] not defined.

I understood struts 1.3 is not suited for working javascript.
Its interactive form always should initialize in Action, then what is meaning of dynamic form..?
