RE: Help needing regarding implementing JAAS for a Web application
Sudhir, Are you deploying your webapp outside of WebLogic? The answer to your question really depends on the web container you are using. For example, I don't *think* there is any 'production' ready support for a JAAS Realm in Tomcat. If you are deploying to the WebLogic web container, then RTFM the WebLogic security docs. They are pretty good. JAAS is an integral part of J2EE and is provided by the container ( I don't think WL 6.x provides *authorization* with their JAAS implementation, however - only authentication ). If you are using/can use container security, there should be no need to write your own LoginContext and callback handler, AFAIK. Also, if you are using container (declarative) security, if your security requirements are simple enough, you won't have to write ANY code. That's the idea behind JAAS being in the J2EE spec. BTW - your JAAS config file is located by using: -Djava.security.auth.login.config=file://path/to/a/config/file on the command line. HTH, Mike -Original Message- From: Sudhir S.

RE: Struts 1.0.2 checkbox - Error Message: No collection found
Yanhui,
I too am still having this problem. When there is data in the Collection,
_it works_. When no data/empty, I get the JspException: No collection found
error - even when wrapped with present tag. Hard to believe we're the only
ones having this issue. Makes me think it's us, but what could it be?
Frag from JSP:
logic:present name=OrderForm property=svcEquips/
logic:iterate name=OrderForm property=svcEquips id=svcEquip
bean:write name=svcEquip property=some key/
/logic:iterate
logic:present/
The parent form (OrderForm):
.
public void
setSvcEquips(com.frontiercorp.bss.cap.proto.bpo.web.OrderSvcEquipForm[]
svcEquips)
{ this.svcEquips = svcEquips; }
public com.frontiercorp.bss.cap.proto.bpo.web.OrderSvcEquipForm[]
getSvcEquips()
{ return svcEquips; }
}
(Most of) the stack trace:

Subject: RE: Struts 1.0.2 checkbox - Error Message: No collection found
Thanks for quite a few very kind people who spent a lot of time trying to
help, but I've not found the solution yet. Here is our problem again,
please help us if you find a way to solve this problem:
1. There is a class called ConflictBean which has a few String attributes
and a boolean attribute called isChecked to record if the jsp user checked
this bean.
2. The Action constructs a few of these ConflictBean objects, stores them in
an ArrayList, then sets this ArrayList in the ActionForm bean.
3. The JSP page iterates through the ArrayList to build a table so that each
row of this table represents an element on the ArrayList (a ConflictBean
object). All the attributes of the ArrayList element, the ConflictBean
object are displayed in different column (cells) of this row. A checkbox is
provided somewhere in each row (say in the most left column) so that the
user can view all the rows, then he can select all/some/none of the rows
(the ConflictBean objects). After the form was submitted, the Action needs
to get the list back out and see which ConflictBean were checked.
Please tell us if we have to use an indexed property such as the checkbox in
the newer version to accomplish this or there is a way to do it with version
1.0.2? Answering this question will point us to the right direction.
THANKS!
Yanhui

RE: Struts Config Problem - Ryan Norman
Ryan,
Please include more detail than it is not working, like what the error or
exception thrown is. Otherwise we can't help troubleshoot.
Also, if it's an option, you may want to take a look at declarative
security. The container manages the authentication and authorization
procedures. You have an option of FORM (HTML login form, in which you
basically post j_username and j_password to j_security_check), or BASIC, in
which case the user is prompted by the browser (popup window) for user and
passwd.

Hi All,
I am Ryan Norman
I am trying to put together a simple sample application.
Right now I have a login page upon submitting the user name and password I

For some reason, it is not working.
Can somebody help me with this?
I am pasting my code and struts-config.xml file contents.

This is a blank Struts configuration file based on the example
application,
with commented examples of some items.
NOTE: If you have a generator tool to create the corresponding Java
classes
for you, you could include the details in the form-bean declarations.
Otherwise, you would only define the form-bean element itself, with
the
corresponding name and type attributes, as shown here.

Hi
All,
I have a
form with an array of subforms on it, like so:
class
BigForm extends ActionForm
{
SubForm subFormX[];
public SubForm[] getSubFormX() { return
subFormX; }
public void setSubFormX(SubForm[]
newSubFormX) { this.subFormX = newSubFormX; }
//
other attributes...
}
When this
has no data in it, and I use iterator on it, like so:
(assume
"TheBigForm" is declared w/ type BigForm in
struts-config.xml)
logic:iterate name="TheBigForm" property="subFormX"
id="subForm"
bean:write
property="subFormPropOne" name="subForm"/
/logic:iterate
I get "No
Collection found" ServletException. The BigForm is in request scope, and
in fact if I force-feed it with data, everything works OK. I also wrapped the
iterate block with logic:present to no avail:
logic:present name="TheBigForm"
property="subFormX"
...
/logic:present
Also, I
initialized the array to new SubFormX[0] - again, no luck.
What is
the correct way to handle this situation - where you have a sub or child form
with an empty array?
TIA,
Mike

RE: Why Struts - Ryan Norman
Ryan, 1) There may be MVC frameworks available as value-adds to WebSphere, WebLogic, etc. They may not port from one app server to another. Struts should run in any JSP/Servlet spec-compliant web container. With proprietary frameworks, you risk getting precisely what many hope to avoid by implementing J2EE solutions: vendor lock-in. Plus, with Struts, you have the (IMHO) benefits of Open Source. 2) We are using Struts with JBoss 3.0b/Tomcat 4.02 integrated.

RE: Struts 1.0.2 checkbox - Error Message: No collection found
Yu,
This looks like the same problem I posted this AM (subject = logic:iterate
and no collection found). I found that if the array actually has data in
it, everything works OK. It's only when it's empty or null that it blows up.
Post if you find a solution and I will do the same. I am going to try to
step through the source this afternoon.
