Re: Re: How to digest a customized struts configuration
Hi Joe, thank you for your usefull hint. Now it flies :) Of course I was quite close. I even tried out different "addSetNext" methods. Following your hint I knew I had to change something else. But I missed to add a corresponding "add"-method to my "ActionMapping" sub-class. Once again: thank you for your advise. If anybody is interessted to the solution I would post it under this thread. Otherwise I won't looking at the traffic of this thread.

How to digest a customized struts configuration
Hello,
I posted this message a few days ago. Unfortunately I
didn't get a helpful reply. I think I choosed the
wrong subject and that's why I re-posted the message
once again:
I want to ask you for help concerning an extension of
the struts config
dtd
and how to make these extension available in the
javabeans,
respectively. In
my case the "roles" tag isn't enough why I added a
"security-constraint"
tag.
Within a sub-class of RequestProcessor I would like to
check if the
user in
role satifies the security-constraint to call the
corresponding action.
A
security-constraint is composed of a module name and a
function access
permission. To do checking I need to be able access
the
securityConstraint-property of
my SessionActionMapping sub-class if I'm right. But I
don't now how to
tell
the Digester with the right rules how to add the
SecurityConstraint
bean to
my SessionActionMapping sub-class. There's where I
need help.
So first this is how my DTD looks like:
...
I wrote an ActionServlet sub-class to define the
public id of my dtd
for the
digester and activated my ActionServer sub-class threw
the web
deployment
descriptor. Starting my sample application the action
servlet gets
correctly
initialized.
Then I added JavaBeans SecurityConstraint and
AuthConstraint.
SecurityConstraint contains a property authConstraints
type Collection,
getter- and
setter-methods and a addAuthConstraint-method.
AuthConstraint is a
simple
JavaBean
with properties moduleName and functionName and
getter/setter-methods.
SampleActionMapping extends SessionActionMapping and
contains a
property of
type SecurityConstraint. Within the struts-config I
defined my sample
action
mapping globaly for all action mappings.
All this describes works fine. But now the problem
raises. Following an
excerpt from my SampleRuleSet:
public class SampleRuleSet extends RuleSetBase {
public void addRuleInstances(Digester digester) {
digester.addObjectCreate(
"struts-config/action-mappings/action/security-constraint",
"sample.struts.config.SecurityConstraint");
digester.addObjectCreate(
"struts-config/action-mappings/action/security-constraint/auth-constraint",
"sample.struts.config.AuthConstraint");
digester.addSetProperties(
"struts-config/action-mappings/action/security-constraint/auth-constraint",
"function-name",
"functionName");
digester.addSetProperties(
"struts-config/action-mappings/action/security-constraint/auth-constraint",
"module-name",
"moduleName");
digester.addSetNext(
"struts-config/action-mappings/action/security-constraint/auth-constraint",
"addAuthConstraint");
I added my sample rule set using the init parameter
within the web
deployment descriptor. But I didn't find the way how
to tell the
digester to
add the
SecurityConstraint bean to my sample action mapping.
Impatiently waiting for your answers
regards
Sebastian
PS: please excuse my english.

Re: Struts User Roles
Hello Tiago, I can't tell you where you can find documentation concerning "roles". But I have taken a look on struts roles on my own. So I'll write down what I know and maybe you get a hint. The struts config dtd defines an attribute "roles" for the "action" element. The "roles" attribute is optional and may contain a comma-delimited list of security role names. These role names are loaded to the ActionMapping of the related action class during initialization of the ActionServlet and Actions (if you want to know exactly what is done when take a look at the init method of the ActionServlet's source). When an Action's execute method is called an ActionMapping object is passed. ActionMapping inherits the property roles from ActionConfig which is populated with the role names from the struts-config.xml during initialization. Within your action you may access your security role names from the mapping. For convenience there is a method getRoleNames so you get the role names within an array. Hope that helps. I posted a thread last week regarding this issue. But I didn't get a helpful answer. I wanted to define a custom struts config dtd to extend the struts config with an element "security constraint". My problem is still that I don't know how to configure the digester using custom rule sets so my sub-class of action mapping gets populated with my custom tag. Maybe you have an idea or anyone who reads this thread.
