Struts 2 and Velocity
Hi all
I've recently switched from Struts 1.x to Struts 2.1.6 and would like to
continue using velocity to render the view.
I also wish to take advantage of the Struts 2 tag library by using
velocity directly.
From the documentation at
http://struts.apache.org/2.1.6/docs/velocity-tags.html, I see the format
is:
#s**tag **(...) ... #end
However, I'm having difficult using the tags. The following is ok and
works as expected
#stextfield ("label=Employee Name" "name=empname" "size=15"
"maxlength=10")
However, I would like to display fieldErrors as I need by name. I'm
trying the following which doesn't seem to work.
#sfielderror #sparam ("value=username")
#end
The 'end' tag is not expected on this one
Can anybody point me in the right direction?
Thanks
Robin

Does #sfielderror ("fieldname=username") not work, or do you need
multiple fields?

Re: Struts 2 and Velocity
Thanks for your response.
Unfortunately, #sfielderror ("fieldname=username") does not work.
All the current field errors are rendered in an unordered list.
Using struts2 tags, it would be:
field1
field2
OR
These are two tags nested which I'm having trouble translating into
Velocity. Any other ideas?

Re: Struts 2 and Velocity
It might be fieldName; case-sensitive.
I'm not very familiar with the Velocity tag support, but it may be
similar to Freemarker in that some tags are in-line tags, some are block
tags, and decisions were made at some point to try and cover the most
common use-case.
If that's the case then you'll probably have to loop over the field
names of interest.

Hi Dave,
It worked ! It seems to be case sensitive. Thanks for your help.
Can you please tell me how you knew to specify 'fieldName' ? I cannot
find it documented anywhere

Well I thought as much but, so far, a scriptlet is the only way I know
of to make the setting above. I know that scriptlets are the old way of
doing things. I'm hoping that there is a new way to do this. JSTL
perhaps? How would one set a response header in JSTL, assuming that it
is possible?

AFAIK you can't use EL inside a scriptlet.
Well I thought as much but, so far, a scriptlet is the only way I know

You've missed my point: the code inside scriptlets is written verbatim
to the generated Java source: EL is meaningless in Java source. You'd
need to get the properties you're using in EL from a scoped attribute,
just like servlets/JSP, or from the value stack.

prepare{MethodName} not working
Hi,
While referring the below link I came to know that we can have
prepare{MethodName}() that will run before the invocation of the particular
method.
http://struts.apache.org/2.1.6/docs/prepare-interceptor.html
I was trying the same. In my action class, I have a save() method and the
action class is implemented with Preparable Interface. But when I add
prepareSave() I get a error
"The method prepareSave() of type ManageGeneralSetupAction must override or
implement a supertype method".
Do I need to override any other method or do I need to implement any other
Interface?
Please advice me on this.
Thanks
Praveen

john feng wrote: > Putthese code in servlet or action class. don't put in the jsp file. ... >> is possible? This idea seems promising. So I have an action that results in the jsp in question and I'm using the Convention plug-in. Presumably, I would have to apply one of the *Aware interfaces to the action to get access to the response header. Am I on the right track here?

You probably have the @Override annotation on prepareSave(), and you don't
need it.

Interceptor Use
Hello, Struts 2.1.6 I wish to ensure a user is logged into an application before allowing him/her to execute certain tasks. Would using an Interceptor be a good way to go? My idea is to retrieve session data in the intercept() method of the interceptor and verify a certain attribute is held in the session. If it is not, I would then like to redirect the user to a login page with an appropriate error message. Is this an approriate use of interceptors? Previously, I simply had a verifyLoginStatus() method in a base action class which I extended in actions I wanted to protect. I'd appreciate any thoughts...

This is a very appropriate use for interceptors.

Re: Performance issues in showcase sample struts 2.1.6 application
In particular, look for the section on creating a production profile. The tag library searches various locations for the freemarker templates, the last place it looks is inside the core jar file. Copying the template you use out of the jar will help quite a bit. Also, if performance is a huge concern, check out the javatemplates plugin.
