Subject: Primitive type bean property
Hi All,
A quick question.
Has anyone tried to write the form with property of a 'char' primitive
type?
That is:
public char getC(){...}
public void setC(char c){...}
Is it supposed to work normally? I was doing it and the value was never
set.
I just need to know that if anyone had done it this way and get it to
work.
The reason I'm not using Wrapper class Character... Is because the code
is generated by ejbgen.
Rgds,
Patrick.

RE: need some sample Tiles definitions usage
Hi jim Javaworld gives a good example of using tiles in struts http://www.javaworld.com/javaworld/jw-01-2002/jw-0104-tilestrut.html I guess it will solve the purpose. Regards. A Subject: need some sample Tiles definitions usage I've taken the Login example from Struts in Action and converted it, step by step, to use Tiles. I'm at the point where I've created a definition entry in tiles-defs.xml but haven't been able to figure out how to invoke it. Although the book is generally pretty good with examples, it unfortunately doesn't give one here. Any examples appreciated!

RE: Problem with action chaining
Hi , As pointed out by Mohan, Action chainning is not a good design practice... You can forward from one action to another but they should eb performing completely independent units of work.If two actions are used to complete only bits of work to complete one logical response, then it is a bad design. There is a discussion thread about action chainning in mail archive. Now about your question. What do u mean by forwarding from action 1 tomaction 2?Because if AgencyAction says mapping.findFOrward(create) then this should work as the forward will agin cause the form instance to be created or retrieved from session... But if you are callign execute of the AgencyCreateAction from first action, then it will not work.

Custom Link Tag
Hi,
I am writing a custom tag: MyLinkTag that extends the
org.apache.struts.taglib.html.LinkTag.
MyLinkTag has two fields. They are
showAlways : Boolean alternateLink : String.
The functionality of the MyLinkTag is captured in the following code
snippet:
***
HttpServletRequest request = pageContext.getRequest();
ActionMappings actionMappings =
(ActionMappings)request.getAttribute(Action.MAPPINGS_KEY);
String path = getHref();
ActionMapping actionMapping = actionMappings.findMapping(path);
String[] roleNames = actionMapping.getRoleNames();
boolean userInRole = false;
for(int i=0; iroleNames.length(); i++)
{
userInRole = request.isUserInRole(roleNames);
if(!userInRole){
if((alternateLink != null) !(.equals(alternateLink))){
setHref(alternateLink);
}
else{
if(showAlways){
setDisabled(true);
}
else{
//don't show the link
return SKIP_BODY;
}
}
}//end if !userInRole
}//end for loop
***
The problem is I don't know where to place this code i.e. in which method:
doStartTag() or doEndTag() or doAfterBody() or any other??
What method should I override??
And what should be the return [integer] values??
Thanks in advance.

Re: Custom Link Tag
Place your code in doStartTag as it can return SKIP_BODY to exclude body from
resulting HTML.
return EVAL_BODY_INCLUDE if you want the body to be included

ConcurrentModificationException on ActionErrors
I have a Struts action that is trying to show all of the errors that might occur from
either or both of two subordinate methods. The
code looks like:
...
ActionErrors errors = new ActionErrors();
ActionErrors errors1 = null;
ActionErrors errors2 = null;
Obj1 obj1 = new Obj1();
Obj2 obj2 = new Obj2();
obj1.method1();
errors1 = obj1.getErrors();
if (!errors1.isEmpty()) {
errors.add(errors1);
}
obj2.method2();
errors2 = obj2.getErrors();
if (!errors2.isEmpty()) {
errors.add(errors1);
}
...
Problem is I get the ConcurrentModificationException when I try and do either of the
errors.add methods above. Methods
method1/method2 are pretty vanilla, just doing some database work and accumulating any
errors in an associated ActionErrors.
I've searched the archives but only found one or two references to
ConcurrentModificationException and they did not involve
ActionErrors. Any ideas or help is appreciated.

RE: ConcurrentModificationException on ActionErrors
Paul,
Thanks I had seen the exception javadoc. An in one of my subordinate methods I do have
a logging snippet that uses an Iterator to
display ALL of the contents of the ActionErrors. And I imagine that my subsequent use
of the ActionErrors.add(ActionErrors) method
also uses an Iterator to enumerate the ActionError objects. Is there anyway to close
the first Iterator so that it does not cause
this conflict?
Thanks again - Richard

Re: ConcurrentModificationException on ActionErrors
It almost sounds like your code isn't handling errors1 and/or errors2 in a
thread-safe manner. ConcurrentModificationException will be thrown if one thread
is in the proces of iterating over a collection and another thread modifies that
collection. ActionMessages.add(ActionMessages) will iterate over both the arg's
properties and the messages for each property, so there's certainly the
potential for the error you're seeing. Can you provide some more detail on how
your code is organized?
BTW, not sure if it's a c/p error, but you've got:
if (!errors2.isEmpty()) {
errors.add(errors1); // shouldn't that be errors2?
}

Re: ConcurrentModificationException on ActionErrors
Could you show the implementation(s) of your ObjX.getErrors() methods. I'm
guessing there's probably a better way to do what you're trying to do.
It probably has something to do with the implementation of:
http://jakarta.apache.org/struts/api/org/apache/struts/action/ActionMessages.html#add(org.apache.struts.action.ActionMessages)
which calls:
http://jakarta.apache.org/struts/api/org/apache/struts/action/ActionMessages.html#properties()
which returns an Iterator, which, as described below probably throws your
exception.
It sounds like the ActionErrors instance you're adding may be the same one
you're trying to add it to.

So is it a bad design if you have Action1 - add CollectionOfObject1 to request Action2 - add Object2 request And then chain them together to produce two request attributes?

So I define action path 1 to be action 1 and forward to the display for the Collection of Object1, and define action path 2 to be action 1 forward to action 2 forward to editor page which has a select of collection of object 1, while editing Object2.

RE: ConcurrentModificationException on ActionErrors
Ben,
The implementation is a pretty simple getter. The ActionErrors object is built by
the call to obj1.method1().
/**
* Get ActionErrors object
*/
public ActionErrors getErrors() {
return errors;
}
The actual code for obj1 is very large (1900 lines) and of course 99% is not relevant
to the issue (but which 1% is :) ) so I
hesitate to attach it.
The obj1 and obj2 objects (not their actual names) are actually DAO objects that take
as input a Struts form bean and update and
add/chg/delete the corresponding database object. All of the edit, error and mapping
code is included (generated by XDoclet) so its
huge (actually compiles small, but being generated its quite verbose).
If I cannot figure this out, I will go back to a simpler strategy. I had weanted to
let the user see all errors at once, rather than
showing them some, having them correct them and then showing them more.
Thanks again - Richard

Struts Workflow Extension - backwards workflow
I am using the Struts Workflow Extension in a sequence of pages, with one workflow per page, to prevent users from navigating with the browser buttons, and this works very well. I would however like to have my own back button on some pages so that the user can go back to a page with attributes etc reset first. I've tried quite a number of configurations of workflows but have failed to get it working. Adding my own back button to the workflow either: 1. re-enables the browser back button on that page, or else 2. causes problems on the page that has been returned to - the submit/next-page button for that page now generates a previous state violation. I am not sure whether I am missing something obvious or whether what I am trying to do is infact logically impossible. If anyone has implemeted this type of workflow successfully, any advice would be much appreciated. Regards, Richard Newton.

RE: ConcurrentModificationException on ActionErrors
Although it's possible to generate that exception from within the same thread,
it's usually triggered by multiple threads accessing the same collection. In
general, if you grab an iterator, then modify the underlying collection, and
then call iter.next(), you'll see that exception. Having multiple iterators
shouldn't be an issue - you don't explicitly close an iterator like a database
connection. It will be GC-ed just like any other object. The problem really
boils down to modifying the backing collection while iteration is in progress.
By in progress, I mean doing something like calling iter.next(), not that
there's just an iterator instance lying around.

if (!errors2.isEmpty()) {
errors.add(errors1);
}
...
Problem is I get the ConcurrentModificationException when I try and do
either
of the errors.add methods above. Methods
method1/method2 are pretty vanilla, just doing some database work and
accumulating any errors in an associated ActionErrors.
I've searched the archives but only found one or two references to
ConcurrentModificationException and they did not involve
ActionErrors. Any ideas or help is appreciated.

Re: Key words in struts-config.xml
Could you provide your struts-config.xml file as well as any output from your servlet container indicating what errors happen when you try to load the application?

RE: Problem with action chaining
On Wed, 31 Dec 2003 12:36:33 -0500, Tim Lucia wrote: So is it a bad design if you have Action1 - add CollectionOfObject1 to request Action2 - add Object2 request And then chain them together to produce two request attributes? I have some pages which display a list of Object1, and other pages which require the Collection to populate a select. So I define action path 1 to be action 1 and forward to the display for the Collection of Object1, and define action path 2 to be action 1 forward to action 2 forward to editor page which has a select of collection of object 1, while editing Object2. One common strategy is to use one action as a page controller and another as the business transaction controller. The business action works as a go between with the business API and DAO objects. The Action class extracts any needed input from the ActionForm and packages for the API/DAO objects. If appropriate, it also bundles any output and places it in a servlet context, sometimes by populating an ActionForm, other times by creating some other bean. The page action ensures that whatever assets the page needs are available. These may be lists for drop-down boxes and so forth. This may also mean interacting with the API/DAO objects, but the interaction is static and driven by the page display requirements, rather than what the user input.. As mentioned, each of these actions should represent a single unit of work. The business Action is an adapter for the user input. The page Action is an adapter for the page output. The core idea is that Actions are Adapters -- not the actual working classes. When people start chaining several actions together, it is usually a signal that the Actions classes are doing actual work, rather than just acting as a go-between with the business classes. The problem with Actions doing the work is that these classes are bound to Struts and to the HttpServlet platform. Struts Actions are not easy to reuse outside of Struts and are more difficult to test than POJO business classes. Creating your own set of business API or DAO classes isn't difficult. You can use a PlugIn to create a instance of your classes in application scope under a known name and then have the Actions call them there. Just be sure they are thread-safe, like Actions. Or, depending on your circumstances, Actions can create new instances of business classes so you don't have to worry about thread-safety. Object creates are a lot cheaper than they used to be. If several of the page or business Action classes need to do the same thing that isn't business-related (create some presentation collection or what-not), you can put that code in a base Action that any subclass can call. In that way, you get code-reuse the old-fashioned way, instead of by making multiple trips through the HTTP layer.

Re: JAAS and roles attribute of logic:present
I am using form based authentication. If I was to secure the entire application how can I assign a role to user's who have not logged in? Karr, David wrote: Are you using basic auth, or form auth?

Serving up Tiles based on Role
I'd love to serve up a specific tile based on a role, but it doesn't seem like it's currently possible in the Tiles Framework. Basically, I want to do the following: !-- User Profile definition -- definition name=.userProfile extends=.mainMenu put name=title.key value=userProfile.title/ put name=heading.key value=userProfile.heading/ put name=content value=/WEB-INF/pages/userProfile.jsp role=admin/ put name=content value=/WEB-INF/pages/userDetail.jsp role=tomcat/ /definition In this example, users with role admin get the userProfile.jsp, while users with a tomcat role get the userDetail.jsp. Unfortunately, role is not an allowed attribute on put. It seems it's only possible to do this on a definition level - but then they cannot be the same name, and it seems rather clunky. For the definition stuff, it'd be nice to do: definition name=.userProfile extends=.mainMenu put name=title.key value=userProfile.title/ put name=heading.key value=userProfile.heading/ put name=content value=.meatOfPage/ /definition definition name=.meatOfPage path=/WEB-INF/pages/userProfile.jsp role=admin/ definition name=.meatOfPage path=/WEB-INF/pages/userDetail.jsp role=tomcat/ Any tips are appreciated.

Re: Serving up Tiles based on Role
Role based tiles is possible in the Tiles framework by putting your own controller before the tile definition. The pdf document, http://www.lifl.fr/~dumoulin/tiles/tilesAdvancedFeatures.pdf gives an example of how to do this at Cedric Dumoulin's site, http://www.lifl.fr/~dumoulin/tiles/ Happy New Year, Tin Matt Raible [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I'd love to serve up a specific tile based on a role, but it doesn't seem like it's currently possible in the Tiles Framework.

This will start out as an alpha, and then may proceed to beta, and even General Availability (stable), depending on the votes of the committers. Other than these issues, it shouldn't be any different than the nightly build though.

Bean As A Parameter In A Method - Compilation Error
I followed the MVC design. I give the data access
activity (insertThread) to the ThreadHandler class.
And a bean is passed as a parameter of the
insertThread method. However, I got compilation error
saying that
insertThread(java.lang.String, java.lang.String, ... ,
java.sql.Timastamp, int, ... ) cannto be applied to
the ThreadBean.
and the error complains the statement in my action
class:
threadID = thandler.insertThread( threadBean );
This is what I did in the action class:
ThreadHandler thandler = new ThreadHandler();
ThreadBean threadBean = new ThreadBean();
BeanUtils.copyProperties( threadBean, postForm );
if (parentPostID == 0 ) // new topic
{
threadBean.setLastPostMemberName( memberName );
threadBean.setThreadCreationDate( now );
threadBean.setThreadViewCount( 0 );
threadBean.setThreadReplyCount( 0 );
threadID = thandler.insertThread( threadBean );
}
and this is what I did in the ThreadHandler class:
class ThreadHandler extends ThreadBean
{
String receiver = getReceiver();
String sender = getSender();
String title = getTitle();
String lastPostMemberName =
getLastPostMemberName();
String threadTopic = getThreadTopic();
String threadBody = getThreadBody();
Timestamp threadCreationDate =
getThreadCreationDate();
int threadViewCount = getThreadViewCount();
int threadReplyCount = getThreadReplyCount();
public ThreadHandler() {}
public int insertThread( String receiver, String
sender, String title, String lastPostMemberName,
String threadTopic, String threadBody, Timestamp
threadCreationDate, int threadViewCount, int
threadReplyCount ) throws MessageDAOSysException
{ }
}
