RE: Struts-EL and JSP 2.0

[Karr, David]

Just so it's clear, you not only don't need it, but it's presence would
probably cause subtle (well, maybe not so subtle) problems.  Don't use
it in a JSP 2.x+ container.

You don't need it since EL evaluation is made by the container with JSP 2.x.

Thanks.  That solution didn't quite work (I didn't need to reference the
"map") but led me to try something similar which worked.

I have not been able to get the same behavior to work using JSTL and EL.
For example the following fails (and I've tried a bunch of other guesses to no 
avail):
 gives "unable to find value for someProp in 
object String"

Is there a way to get the same functionality without using the Struts tags?


The first issue I see is that you need to find the form itself, using
'param.formName' as the key into the session or request map.  I think
you're going to have to know where the form is stored for this to
work.

Then you need to get the property out of the form.  You said it's a
dynamic form, so you'll need to go through the form's 'map' property
to do that.

Try something like this:

 

You may want to split it up with a , to make it more readable.

Now someone will probably point out that I'm making it far more
complicated than it needs to be. :)

Re: Struts-el and Weblogic 9.1

[Mujahid Ali]

Weblogic has an option where you can force it load classes from the 
WEB-INF directory. I did that to eliminate any potential class loading 
conflicts...
Still the same issue. I found a known issue 
http://edocs.bea.com/wls/docs91/issues/known_resolved.html#1056681 
[CR210907] :


   Netui databinding expression language fails when BeanInfo overrides
   JavaBean property names.

   Evaluation of expressions in the Netui databinding expression
   language throws errors when BeanInfo netui databinding EL does not
   to work when java.beans.BeanInfo is used to override JavaBean
   property names.

   *Workaround or Solution*:

   Do not override JavaBean property names using BeanInfo if you use a
   JavaBean in Netui databinding. If you must databind to such a bean,
   wrap the bean in a UI version of the bean that follows the JavaBean
   property naming convention.

Struts-el is essentially doing the same thing with mapping the property 
names using BeanInfo for each tag class.


This is just a guess, at this point I am running out of idea...

Servlet 2.4 is an option, just have a very large application that we 
will have to figure out how to port over...


Thanks for all the comments/suggestions.

9.1 used 2.4 and it is supposed to be backwards compatible. Just to make

comes with the struts 1.2.8 release.


The tags don't work without any modifications to the war. If I modify

Here is the web.xml as modified to reflect 2.4 changes:

Since you're using Tomcat 5, as Michael pointed out, you have the
option of moving to Servlet 2.4 and JSTL 1.1.  In that case the
container will evaluate expressions before passing them to the Struts
taglib, so you don't need Struts-EL.

You can also continue using Servlet 2.3/JSTL 1.0 on Tomcat 5.5 -- it
will work fine.

You don't need Struts-EL on Tomcat 5 because it supports SRV2.4/JSP2.0/JSTL1.1.

Also it seems that you confuse Struts-EL with JSTL. These are different things.

RE: [Struts EL & JSTL]

[Karr, David]

To answer this a little differently than Laurie did, the Struts-EL tag
library is a collection of tags that all inherit the behavior of the
Struts tags they replace, except the tag attribute values are passed
through the JSTL expression evaluation engine implemented by the Jakarta
standard taglib implementation.

The Struts-EL tag library is only useful in a JSP 1.2 container (or in a
JSP 2.0 container if not specifying the Servlet 2.4 spec).  If you have
a JSP 2.0 container, and you specify the Servlet 2.4 spec, then EL
evaluation is done "natively" in the container, so you don't need a
special tag library to implement it (and it would probably cause
unexpected problems if you used it).

If you just used the Struts tag library, then attribute values in the
Struts tags like "${stuff}" would just produce the value "${stuff}".  If
you were instead to use Struts-EL, then it would produce a value based
on the value of the "stuff" scoped attribute.

In fact, the Java classes in the Struts-EL library all inherit from the
corresponding Java classes from the Struts tag library, it's just their
setters/getters that cause the values to be passed through the EL
engine.

I've used JSTL 1.0 tags and see how there is overlap between some of the
Struts logic/bean tags but I fail to see what exactly Struts EL is.

I've read http://struts.apache.org/struts-el/index.html
  but I still fail to see
what it is.


The EL tags are variants of the standard tags that know how to evaluate 
JSTL expressions. They're useful when you're running on a pre-JSP 2.0 
container which doesn't do this automatically.

The struts-el-1.3.0-dev.jar file is there. By "libraries" do you mean
the tld files?

If so, they are inside the jar, but normally you don't need to extract
them (except possibly to find the URIs).  Try this:
 <%@ taglib prefix="html"
uri="http://struts.apache.org/tags-html-el"; %>

For 1.2.8, you'll want the full binary distribution
(struts-1.2.8-bin.zip) instead.  Then look in the "contrib/struts-el"
directory for Struts EL.

Please let us know if you still can't find what you need.

What you want is:


This will check for a bean stored under the name 'results' in session scope.

${sessionScope.results} evaluates to the bean itself.  The logic tag
receives *that bean* where before it received a String.  I believe
that the logic tag would then convert that bean to a String and look
for an object stored under that name, instead.

Instead of dealing with all of this, just try the following JSTL:

I use EL to replace   
where Constants.RESULT  has value 'results'

Where does the above declaration differ from the EL?

What does  ${sessionScope.result} represent in this case?



can you show me a quick sample on a simple  use of EL ?
if I store objects in session/request/applicationScope, why can't I use

struts-el with EL to retrieve them?

No, because el actually depends on taglib -- you have to have taglib to
use el.

If you're also using JSTL, I would always advise using  
whereever it works -- not that this shouldn't be fixed if it turns 
out to be a bug.

Hello all,
 I have an app which is using struts 1.3.. I wanted to 'replace'
existing struts tag with struts-el tag.
So I downloaded struts-el-1.3.0-dev and put it into my jar, (along with
struts-taglib-1.3.0-dev)

I have declared taglibs in web.xml, and I wrote a simple page which uses
Struts-el inside a logic:tag

And, to my surprise, it did't work 
Basically I have an attribute of type collection in my HttpSession, and

I was trying to access it from the page using




for doublechecking, I wrote a scriptlet code that was trying to get the
'results' attribute from the session, to see that if it was actually
there..
and it was there

Even the c:forEAch loop that uses JSTL to get that attribute works
fine..

RE: STruts-EL

[Karr, David]

Another good suggestion would be to NOT use a different taglib prefix
for the struts-el tag libraries.  In the initial examples, you might
have seen examples like "html" and "html-el".  I don't recommend that
(anymore).  If you use the same prefix, then that will be less to change
when you port your code to JSP 2.0.

These aren't mutually exclusive, typically you'll use the original Struts
taglib alone, or Struts-EL and JSTL 1.0 together [in a Servlet 2.3/JSP 1.2
container].

(Then when you move to Servlet 2.4/JSP 2.0, you go back to the original
Struts tags, plus JSTL 1.1.)

> After reading documentation, i really don't understand why, when and

What typically happens is that you discover JSTL, and then get frustrated by
the fact that you _can't_ use expressions in the Struts taglibs [with JSP
1.2].  Enter Struts-EL, which gives you that ability.

In your example, that runtime expression will not be able to "see" variables
set with JSTL, such as the status of a loop inside  or anything
set with .  Try this:
   <%@ taglib uri="http://java.sun.com/jstl/core"; prefix="c" %>
   
   <%= myval %>
(It won't even compile...)

The flip side of that is:  JSTL cannot "see" scripting variables.  This is
intentional. :)

If you're going to use JSTL 1.0, then you should use Struts-EL along with
it.

It's a lot more clear to compare the difference between:



and

"/>

Especially considering the following scenarios that "just work" in EL:

  -- What if "someObj" may be in more than one scope?
  -- What if there *is* no 'someObj'?
  -- What if someProp is null?

[Niall Pemberton]

The "EL" flavour tags allow you to use "expression language" (EL) in the
attributes of the struts tags in a Servlet 2.3 container (which Tomcat
4.1.31 is). Once you upgrade to a Servlet 2.4 container (e.g. Tomcat 5.x),
which comes with EL support provided then you will need to switch back to
the "regular" flavour struts tags.

If you need/want to use expression language then yes its a good choice - as
is using version 1.0.x of the standard tag library (JSTL). Both allow you to
use Servlet 2.4 features before you actually upgrade to a Servlet 2.4
container.

You can do one thing so that upgrading to a Servlet 2.4 container in the
future is a painless exercise. That is to put all your taglib declarations
into a separate jsp file (say "TaglibDirectives.jsp") as follows:

-- START TaglibDirectives.jsp -
<%@ taglib uri=http://struts.apache.org/tags-html-el  prefix="html"
%><%@ taglib uri=http://struts.apache.org/tags-bean-el  prefix="bean"
%><%@ taglib uri=http://struts.apache.org/tags-logic-el  prefix="logic"
%><%@ taglib uri=http://struts.apache.org/tags-tiles-el  prefix="tiles"
%>
-- END   TaglibDirectives.jsp -

Then in your jsps where you use these tags, you simply include this
directives jsp:

<%@ include file="/TaglibDirectives.jsp" %>

The advantage of doing this is when you upgrade to a Servlet 2.4 container,
all you need to do is change this one file to switch back to the "regular"
struts tags:

-- START TaglibDirectives.jsp -
<%@ taglib uri=http://struts.apache.org/tags-html  prefix="html"
%><%@ taglib uri=http://struts.apache.org/tags-bean  prefix="bean"
%><%@ taglib uri=http://struts.apache.org/tags-logic  prefix="logic"
%><%@ taglib uri=http://struts.apache.org/tags-tiles  prefix="tiles"
%>
-- END   TaglibDirectives.jsp -

This also works well for the "JSTL" tags - because their URI changed from
JSTL 1.0.x (for use with Servlet 2.3) to JSTL 1.1.x (for use with Servlet
2.4)

Hmmm!  I must have missed that in the docs.  Thanks!
So for the same functionality, I should include the JSTL _and_ Struts 
taglibs in my JSPs and write expressions with abandon?  And perhaps that 
explains why the struts-el webapp doesn't work with Tomcat 5 ...

hihi Morris,

sorry but i have to ask, why do you need the struts-el library when you

Tomcat 5 already has EL capability built-in.

RE: Struts-EL with Hibernate and LazyInitializationException (no session)

[Marius Botha]

Thanks David,

I thought "loading the object directly before putting it in the scope" would
be the best option for now, but will check out the hibernate docs.

Our controllers and hibernate mapping file is generated from a UML model.
The mapping file specifies that the collection should be loaded "lazily".
What I am doing is I am calling a method on an object called Resource that
will attempt to go through all the user's properties (a collection) and find
the object in the collection that matches and then return it. However, the
collection has not been initialized at that time and that is when I get the
exception.

Thanks again.

Marius

Marius,

In Hibernate when you use Lazy initialization it means no attempt is made to
read your data from the database UNTIL you ask for a component of the
object.  So, if you save your object to a scope (request, session, tile,
application) and close your "session" object.  You might get around this
problem if you put your Session object into the client's session scope but
that would eat up connections.  I recommend you check out hibernate.org's
suggestions on this in their documentation.  Offhand, I would suggest
loading the object directly before putting it in the scope.  How are you
"lazily" loading it?

Hi there,

I'm hoping someone out there have some experience with struts and Hibernate
and can point me in the right direction. I'm fairly new to struts and have
actually been using JSF, Hibernate and JBoss for the last couple of months
so this was my only reference point. In JSF using the EL is quite powerful
and I believed I would have the same functionality in struts but must be
missing something somewhere

My Hibernate and JBoss experience is also very limited so please excuse me
if I'm not technically correct. I use Hibernate, which Lazily initializes
the objects and collections as required all running in JBoss. I created my
own JSTL calendar tag to use with struts, the parameters of which is
populated using the standard expression language. For example:



The "user" object is of type Resource.class (my own class) which contains a
collection (lazily initialized by Hibernate) called "userProperties". The
getDateFormat() method reads from this collection and is supposed to return
the user's date format preference.

This works perfectly if I use any other normal String property for example
like ${user.name}, which is initialized when the object is added to the
session (I think...?). Using JSF this also works perfectly as faces seems to
manage the EL and Lazily initialization of objects differently (i.e. without
any problems). However when I use struts, this fails and I get the exception
below. I think it indicates that the tag cannot find the Hibernate session
associated with the current user at runtime. I had a similar problem with
ActionForms, however I created a servlet filter which wraps the request in a
user transaction, but it doesn't seem to work...

Any help or hints will be much appreciated.

Thanks,

Marius Botha

If you download struts and unzip the file it will have 3 directories:  
contrib, lib and webapp
look in contrib/struts-el

Though, if you are using tomcat 5 (which has JSP2/JSTL1.1) then you 
don't need struts el, just use the normal struts tags as Tomcat takes 
care of the EL expressions.

Thanks Claudia

It's in the standard Struts source distribution (or CVS), under
"contrib/struts-el".
