Define tag cannot set a null value' error
I need help with a Define tag cannot set a null value' error I get. I have a state and country that _is_ null, when the user first comes into this form for the first time. I do validate this when they submit the form, but I don't get that far. Can someone please help me with this?

RE: Help needed in define tag..........urgent
To begin with, what's the point of storing the package name in a variable? The problem is that test2 is assigned at run time, while type is assigned at compile time (or is it the other way around? - I forget). The container is trying to assign a package name to type that doesn't yet exist.

Help with define tag
Hi,
I think I'm missing something here. I have a bean that is available to my
page in the request scope. Within that I have another bean that has
properties I want to display. I'm trying to use the define tag to get a
reference to the embedded bean and I'm getting the infamous:
javax.servlet.jsp.JspException: No getter method for property homeAddress of
bean policyHolderInfo
Here's the code -
In my bean policyHolderInfo bean attached to the request obj:
public AddressInfo homeAddress;
public AddressInfo
getHomeAddress(AddressInfo homeAddress)
{
return homeAddress;
}
public void
setHomeAddress( AddressInfo homeAddress)
{
this.homeAddress = homeAddress;
}
My jsp tag is:
bean:define id=policyHolderAddress name=policyHolderInfo
property=homeAddress /
All other getters on the policyHolderInfo bean work just fine.
Am I doing something wrong or is there another way to do this? Any
suggestions would be appreciated.
Thanks,
Chuck
Re: Help with define tag
Is your getter method really as you posted it? That just returns the
parameter it is passed. It should be this:
public AddressInfo getHomeAddress()
{
return this.homeAddress;
}
Note the absence of the parameter. The rest looks fine, although I would
advocate making the homeAddress member private instead of public.

Your property support must looks like -
public AddressInfo
getHomeAddress()
{
return homeAddress;
}
public void
setHomeAddress( AddressInfo homeAddress)
{
this.homeAddress = homeAddress;
}

define tag
Hi If we use struts-bean:define tag and if the variable is not found, does it raise exception. If yes how can I catch it and handle it. Normally if A is in Sesion scope and a property B then we would do bean:define id="m" name="A" scope="session" type="typeA" / bean:define id="B" name="m" scope="page" type="typeB" / Now if for some reason we cant find A in the session or say A is null, we cant put a series of if conditions in the jsp. How are we supposed to handle such scenarios Thanks Hunt __ Get personalized email addresses from Yahoo! Mail - only $35 a year! http://personal.mail.yahoo.com/
