Re: Design Advice - Relational Databases Java Objects
(1) Is it best for the data access layer to throw exceptions on error to be picked up by the business objects then struts actions, or would it be good to use a struts-type message object and use strings in the application resources file (I'm just worried my exceptions' text would not be multi-lingual) In the event of a real emergency, the data access layer should throw exceptions, which your business layer can catch. I find chaining exceptions to be very effective. http://www.javaworld.com/javaworld/jw-08-2001/jw-0803-exceptions.html You can add your own business explanationa at the top of the chain and show both the business explantion and the actual cause. The business explanation calms the mere mortals and the actual cause helps tech support with problem determination. The Struts message system builds on the standard Java ResourceBundle framework. So I would say that it is perfectly valid for your business objects to return tokens from the ApplicationResource file. This file can be used in any application and is not Struts-specific. (Especially if you are using the message tags from Struts 1.1b or 1.0 version of the Validator.) If you really want to hedge your bets, write your own business layer first. This layer takes the input each business operation requires and hands back a Collection, Object, or maybe just a status code. Internally, the business layer takes the input and connects to the data access layer (JDBC, Castor, Turbine, whatever). This can also let you chain the exceptions or do whatever other handling you need to make. Your business layer becomes bound to the data access layer but can be changed without touching the web tier. This also makes it easy to use multiple data access devices. You might need to use Castor for some things and Lucene for others. The business layer can provide a consistent interface to the application platform (Struts, Swing, whatever), and then choose whatever source it wants to use for data. This would also include manufacturing data for testing or debugging. Chapter 12 and 13 of Professional JSP Site Design from Wrox show using this approach for JDBC and then integrating Lucene for some of the searches. Struts is used by the example application here, as it is throughout most of the book. http://jakarta.apache.org/struts/resources.html#books (4th from the top) The Action's role is to bundle the input from the ActionForm bean into whatever input the business layer expects. The Action then either forward the result along or cope with any error condition. (2) How would I get the database connection info to the data access layer? Presuming I want to set it up in struts-config.xml or as in commons-dbcp, would I then pass it in from struts actions into the business object and then into the data access layer as a parameter on each call? As mentioned elsewhere, getting a database connection from the web tier is not a good practice. The Struts framework does try to encourage best practice but sometimes takes a dip in the pool of pragmatism. The Generic Connection pool is one example of this. The data access objects should take care of all the connection stuff and just pass back standard Java objects like JavaBeans and Collections. The web tier, and even business tier, does not need to know where the data comes from. -- Ted Husted, Husted dot Com, Fairport NY US -- Developing Java Web Applications with Struts -- Tel: +1 585 737-3463 -- Web: http://husted.com/about/services Adam Hardy wrote: Hi All, I saw this thread in the archives and I thought I'd pinch the title. I've spent this afternoon surfing the web looking at stuff on Sun, Jakarta and lots of smaller sites looking for a ready-made data access layer package but I take it there isn't an open-source one out there. Obviously I don't want to tie my data access layer to struts, so there are a few questions I've got.

I've seen quite a few patterns like www.martinfowler.com and code like in Sun's Pet Store, so I think I've got a fairly good idea of what I need. The data access layer I want has got to: - take as input and return as output Data Transport Objects - allow the business objects to control transactions - use a connection pool - possibly keep the SQL statements in an external XML file - have comprehensive error handling reporting -- To unsubscribe,
Problem with GenericDataSource
I am using Struts 1.0.2 and I have a problem with the GenericDataSource object:
when I try to close the source, everything hangs.
What am I doing wrong?
try{
GenericDataSource dataSource = new GenericDataSource();
dataSource.setAutoCommit(false);
dataSource.setDriverClass(oracle.jdbc.driver.OracleDriver);
dataSource.setPassword(password);
dataSource.setUrl(url);
dataSource.setUser(user);
.
dataSource.open();
Connection conn = dataSource.getConnection();
.
.
conn.commit();
if (conn != null) {
try {
conn.close();
} catch (SQLException f) {}
conn = null;
}
if (dataSource!= null){
dataSource.close(); // here everything hangs...
dataSource = null;
}
}catch (Exception e){
e.printStackTrace();
}
Any good ideas?
After a while (not beeing able to close the source) I get the following exception:
java.sql.SQLException: ORA-00604: error occurred at recursive SQL level 1
ORA-04031: unable to allocate 4128 bytes of shared memory (shared
pool,DATABASE,sga heap,multiblock rea)
is this due to the fact that the source did no get closed properly?
And why is GenericDataSource deprecated in later versions?

RE: a newbie question on iterate
The answer, unfortunately, is all of the above. The iterate tag iterates
through both maps and collections in any form and in any scope, and you
display the contents of map and collection values with the bean:write tag.
A typical map would be key-value pairs placed in memory as
session.setAttribute() objects, whereas typical lists are placed in memory
by the ActionServlet instantiating a JavaBean (as a Struts form bean) and
making it's getters (accessors) and setters (mutators) available to JSPs and
Action classes.
For example, let's say you want to display a list of cities for a particular
state when a user selects a state from a drop-down list in a JSP. First,
how would you populate the states list? It would be pretty tedious to
hard-code 50 states + D.C. + any territories (like Puerto Rico or Guam) into
the JSP as HTML select options, not to mention bloating the source code.
With Struts, however, this is a piece of cake:
1. User is forwarded to the states/cities page from some JSP through some
Action Mapping that uses an Action class that in turn requests a List of
states from a DAO (data access object - a helper class concerned only with
querying the database).
2. The Action class takes the List and puts it into application scope (in
this case, since the List can be reused by any other clients):
ServletConfig.getServletContext().setAttribute( statesList, states);
3. The states/list JSP can then display this List of states as an HTML
drop-down:
html:select name=states
logic:terate name=statesList
property=states
scope=application
type=com.company.dao.state
id=state
html:option value=%= state.getName() %
%= state.getName() %
/html:option
/logic:iterate
/html:select
4. A JavaScript onchange() event handler can then call the Action class
to request a list of cities from, say the city DAO (City.java), based on the
selected state and populate a City drop-down select box in the same
manner.
This is about as simple as it gets, but note that using JSP scripting
variables is generally frowned upon by the purists. But I hope you get the
idea and then can move on to using the html:options tag. Note that the
List could also have been stored as a TreeMap and you could set the option
values with something like state.getAbbreviation(). The various attributes
are explained in the Struts tag documentation.
To use a JavaBean (Struts form bean - a special use of JavaBeans that use
only booleans and Strings) with a JSP, you simply create a bean with
mutators and accessors matching the names of the input objects in your HTML
form contained in your JSP. For example, if you have a form taking user
info:
html:form action=/do/userInfo method=post
html:text property=fname size=20 maxlength=20 /
html:text property=lname size=20 maxlength=20 /
html:text property=street size=20 maxlength=20 /
html:text property=city size=20 maxlength=20 /
html:text property=state size=20 maxlength=20 /
/html:form
html:submit value=Submit /
You would create a form bean like:
***
package and import statements
***
public class UserInfo extends ActionForm implements Serializable {
private String fname = ;
private String lname = ;
private String street = ;
private String city = ;
private String state = ;
public void setFname( String fname) {
this.fname = fname;
}
public String getFname() {
return fname;
}
/*
same pattern for other fields
*/
public void reset( ActionMapping map, HttpServletRequest req) {
super.reset( map, req);
fname = ;
lname = ;
password = ;
//etc.
}
}
Now, when the user hits Submit, the Action class associated with the path
/do/userInfo will be called by ActionServlet but before the action's
execute() method is called, UserInfo's setters will be called and its
properties set, making them available for writing to the database and/or the
JSP the action forwards to in struts-config (Note that if you want the
bean's info available across a user's session, do not reset the properties
in reset() and declare the bean in session scope in struts-config).
Another JSP can now access UserInfo's properties with bean:write like:
bean:write name=UserInfo property=fname /
bean:write name=UserInfo property=lanem /
etc.
It's easy to get lost in these tags when you first start out, because they
are very powerful and can do a lot of things - much of which is indocumented
and if discovered by trial-and-error and reading this user list. The best
thing you can do at this point, however, is thoroughly read the taglib
documentation.
Good luck!

No, we cannot suggest a better way of doing what you are trying to do because you have not given us the slightest hint of how you are trying to accomplish your pre-visit form population. I suspect that you are relying on Struts to magically populate a JavaBean which in turn would populate the field(s) of an HTML form prior to a client accessing the form. Doesn't work that way. The Struts plugin (I assume you mean the action class) must be activated by a client request. If you want a form to be dynamically populated with data prior to a client reaching it, the client must first request something else (HTML, JSP or action class) that triggers the action class to populate the bean (by calling a DAO, VO, or other helper class that actually makes the database calls). You could redirect to the action if you wanted to hide your implementation by the use of HTML meta refresh to trigger the action (meta http-equiv='refresh' content='0; url=/do/myActionClass') or the % jsp:forward % tag, and the results would be displayed based on your forward path in struts-config.

Using formbean effectively.
Hi, I have an frist.java (action class) and that would keep so much info in several attributes and bound them to request object, and then in first.jsp page i would retrieve all of them and display in FristForm.java controls. I have got an idea to keep all the information in FirstForm bean itself in First.java rather than binding to request in action class and showing it in FirstForm in First.jsp. If any one of you feel this idea is good enough, then how could i put them in form bean ( which has got select,radio buttons) and pass this formbean to First.jsp page to display. Can any one suggest me how to do it and how an action mapping should be coded. TIA rayaku -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: [Struts Tips] #2 - Template Method Dispatch Action?
Why are the Framework and Dispatch approaches mutually exclusive? It seems like you could do both -- have a base action with extension points (hot spots), and the main hotspot method (i.e. 'executeLogic') could optionally be a dispatch method. This would help with create/update/delete operations, where all the logic is the same except for which db operation to perform. Of course it's not the only way to do it -- the 'business bean' approach you mention, where the mapping specifies the business class, would also work nicely. But the framework + dispatch approach could cut down on the number of classes (business bean or action). The business bean and framework + approaches actually seem pretty similar to me. The only difference is whether the main extension point is a separate class, or a method of the action class. In either case the extension point is specified in the configuration file. Steve Molitor I believe the Dispatch and Template (or Framework) class approaches may be mutally exclusive. The idea of the Dispatch class is that you can vector to an arbitrary method. The idea of a Framework class, like SuperAction uses, is that a known entry method calls a number of hotspots (or extension points) that you can override. -Original Message- From: Ted Husted [mailto:[EMAIL PROTECTED]] Sent: Saturday, June 01, 2002 7:31 AM To: Struts Users Mailing List Subject: Re: [Struts Tips] #2 - Template Method Dispatch Action?

However, related tasks often have some common logic that needs to be performed for all the tasks, and other logic that is specific to each task. It would be cool if there was a DispatchAction that provided hooks for the common logic.

The idea of the Dispatch class is that you can vector to an arbitrary method. The idea of a Framework class, like SuperAction uses, is that a known entry method calls a number of hotspots (or extension points) that you can override. You could share common utility methods among various Dispatch methods by passing all needed parameters through the signature, but how to merge this idea with a framework class approach isn't jumping out at me. The closest thing may to be use a relay action to forward the request to another Action based on a framework class. You then just override a business extension method on the framework Action (like SuperAction.ExecuteLogic). This doesn't reduce the number of Actions, but it does let you share as much code as possible Personally, I use very few Struts Actions in an application. Instead I tend to specify a business class as part of the action mapping, and then have the Action call that, using a base Action like the above. The business beans have a hotspot method with a known signature. The Action just instantiates the business bean (like the ActionServlet instantiates a form bean), calls the signature, and copes with the result. (Just like the ActionServlet calls an Action.) This trades Actions for business beans, but minimizes coupling to Struts and maximizes code reuse between platforms. The Advanced Struts skeleton for Adalon, uses the same approach. (No surprise, I wrote it =:) http://synthis.com/products/architectures/struts/ Synthis has released the skeleton code under the Apache License, and I'm integrating it back into the Scaffold package and updating the Artimus application to use the new clases. So, there will major updates to these next week. All the same ideas, but with some improvements to the implementation.

Global-Forwards Question
Hi All, Is it possible to use the mapping.findForward method to forward to another ActionServlet? I have two ActionServlets that both need to forward to a third, common ActionServlet. In my struts-config, I have the following line: global-forwards forward name=thirdAction path=/thirdAction / /global-forwards where 'thirdAction' is the common ActionServlet. In both of the other two ActionServlet, I have actionForward = mapping.findForward(thirdAction); return actionForward; It doesn't seem as though the forward is happening as I never get into the 'thirdAction'. Can this be done this way? Thanks! This transmission (and any information attached to it) may be confidential and is intended solely for the use of the individual or entity to which it is addressed.

servlet context/Action class - performance question.
The requirement is to display a page with some categories just like the yahoo homepage. The link of each main category will have to show the subcategories of that category in a similar page. The level of this tree goes one more level inside. All this information is built ofcourse by retrieving from the database. First thought was to build the relevant section of the category/subcategory tree based on the request parameters. Since these pages are going to be the most viewed (and does not change based on the user), I thought it would be better for performance if the whole tree is created in a startup servlet and put in servlet context instead of creating a part of it in the Action class and setting it into the HttpServletRequest. This would mean that I wont have to hit the database for every user request. I will just have to get the relevant part of the category tree from the (big) object in servlet context based on a key lookup on the TreeMap. The pages load surely very fast, ~but~ I am wary of such a big object in memory and its effect on the performance once it goes into production. To give a rough idea about the size of this tree: 1 main category (TreeMap) has about 12 subcategories (TreeMaps again). Each of the subcategories has about 10 child categories. Each child category is a ArrayList of strings. So its a TreeMap of TreeMaps of ArrayLists. Did anybody face similar design choice and had to choose against a setting so much information in the servlet context? Any input is greatly appreciated!

Re: servlet context/Action class - performance question.
We store much more information that in our application context and dont have any performance issues. We store all our master data (static) on startup. The performance is enhanced.

Re: Configurable UI Design
I'm pulling this over to the Struts list from servlet interest.
Have you signed up for the struts-users list at apache yet?
It's a pretty high-volume list, so make your choice wisely ;-)
Either way, we should be able to finish this thread and anyone at
struts-users please give comments/insults accordingly (since I'm not
always 'the sharpest knife in the drawer' ;-)
A lot of people familiar with Struts and MVC as a whole would ask you 'why'
you would want to do this.
It sounds a little crazy to me, but I think it can be done.
I'm assuming that you are using some other means of 'remembering' your
users (db, ldap, whatever). (if not then @see below)
** Inherent Problems:
(if you are depending on cookies to 'remember' your users)
- users prefs are not remembered if they
1. delete and/or disable cookie(s) (I mean this across sessions
and not specifically within a session)
2. use a different computer (e.g. home pc vs. work pc)
3. use a different browser (IE, NS, Mozilla)
** Validation:
I have no idea how you would handle your input validation,
perhaps some kind of PageManager tag that wraps the jsp and knows how
to handle the validation (or clue-in your action as to what to do)
The Validator framework is.welljust AWESOME if you've ever used it.
I highly recommend *not* deviating from it if possible.
I have posted a few 'how-to's on wizards, so if I were given your
requirements, I would probably follow a similar approach.
My best guess is that this would need to be a highly customized solution,
**DISCLAIMER - I may be biting off more than I can chew.but
here goes...
** Reusing your jsp
If you structure your jsp properly, you can break up a really long
form into several pages (keep in mind the impact on validation)
I think Ted Husted might have given some info on this already
(can't remember, I know, I'm an idiot)
For your questionI'm envisioning/dreaming of something like
this.
(perhaps this could/should be packaged as a component/add-on specific
for jsp views of course)
* A jsp page manager (wizard) that:
- can manage the state of the pages/wizard, (e.g. remember
the 'page ? of ?')
[the verbage could even come from the bundle/config file]
wizards.version1.page1of.= You are viewing page {1} of {2}
wizards.version2.page1of.= Page {0} of {1}.
wizards.version3.page1of.= {0} of {1}
- let's you specify that the user be able to configure the page layout
and fields/views at runtime.
- can figure out that if the user pushes the last input(s) to a page
beyond the last one, it adjusts the page ? of ? accordingly.
Also handles the inverse of that situation.
- enforce the required fields/process flow for the fullfillment of
the form (now that's a tongue twister, or as they say
in AU...'teng twistah';) ...sorry, I have kids and we have
the wiggles over here (US) too...LOL
- auto-magically handles the previous-next-finish for you.
- let's you i18n everything in the bundle(s) similar to what the
validator header/footer requ'd
pseudo-code reality=Don't shoot me if this seems stupid!!
html:form ..
optls:jspManager config=true
optls:page1of/
!-- beginning of dreaming-state--
if your form was 'flat', then it would be nice if you
could use the DynaActionForm and be able to add a field to
your application/wizard simply by adding it to the struts-config.xml
and (optionally) the persistence layer (I have seen and worked with
'dynamic db fields', done through the magic of a well designed RDBMS)
[for those of you who know me, i'm talking about the concept of catalog
attributes]
!-- end of dreaming-state --
!-- if you can't do the above, oh well... do this --
!-- specify your fields here --
optls:userConfigedFields
html:text property=field1/
/optls:userConfigedFields
optls:userConfigedFields
html:text property=field2/
/optls:userConfigedFields
optls:userConfigedFields

/optls:userConfigedFields
optls:page1of/
optls:previous/optls:next/optls:finish/

Thanks. I am familiarizing with the 'tiles' part of Struts, meanwhile a
quick question.
It seems like tiles can help me change personalize the layout of a
single page. I have one more specific requirement. Let us say that my
HTML form is distributed across 2 or 3 separate HTML pages, which are
navigated using back, next buttons. I would like the end user to be able
to personalise by specifying which components of the form are available
on which page. For example, the user may want to move a not-so-important
field for him from page 1 to page 3.

Re: [MVC-Programmers] CachedRowSet - updates limited to single table
Subject: Re: [MVC-Programmers] CachedRowSet - updates limited to single table From: Vic Cekvenich [EMAIL PROTECTED] === A good use for Cached Row Set is as a disconnected collection of rows. I use it to store the data after I do a Select (instead of a collection) A nice feature of RowSet is getMetaData method, that explains the information about the data. I create an update, or an insert or a delete I do so manualy and not use the RowSet. I enumerate the meta data about each row, then I enumerate each column, and create for example a an Update SQL String / Prepared Statment. Look at WebPIM for my Design. It is a generic update. It can be easily extended to do multi table, or you can overide the DAO and hardcode the join update(). Above is a good design. An alternative design is this Create a Company update Form Create a User update Form. When selecting you can do a SQL join and use the JSTL or Display Tag. When updating on a single screen Well you can have multiple users on a page per company. So you would display company and users that iterate. Hence a company form bean that contains a user form beans (and each bean implements iterator). So alternative is a formBean iterator that contains other formBean iterators (thata each have a DAO that uses a disconnected row set for a collection). Very clean, IMO.

I have searched for answers on the 'net and in this newsgroup, and checked up on most of the advices. Apparently I'm not alone (and that's a comfort, after all :). Question 1: How come the struts-config.xml file is so vulnerable and what is done to make it more robust? To me it seems that there is a lot of suggestions on why the problem arises, but they are very different, with no general applicability. Is there perhaps a solution that verifies the file and setup properties (A Do this and it can't go wrong)? Back to my current problem: My Linux (7.2) crashed with two projects that worked - I managed to save the files and have been rebuilding the setup with Tomcat 4.0.2, Struts 1.0.2 and various XML parsers. Now one project works fine, the other project simply gives me the problem no matter what I try.. I tried removing these XML jar's from the $CLASSPATH but it didn't matter. My project needs a JDOM xml-parser so that and the struts.jar file is added to the project WEB-INF/lib. I tried building the app' up from scratch based on struts-blank, with no luck at all (!). Question 2: The struts-config.xml file I use (attached) generates a parsing error in the log and the dreaded JSP exception error page, when I start my application from a JSP page containing: ... html:form action=login.do focus=login ... /html:form ... Can anyone find the blind spot I've been missing? I'm pretty sure that the files and the system setup (including web.xml) is as before the crash, and the jsp-files etc are all in the right places.

Re: multiple frames
Hi Matthias, the frames issue is totally meaningless to struts - each frame acts as an individual page, therefore struts thinks of the requests as normal browser windows. If your index.html has a frameset tag in it, it can't have any other html - it supports the pages in the frames. Your submit button must be in one of the frames - unless you're doing iframes or something. If you want the other frame to be refreshed at the same time, you have to do it with javascript via the submit event of the first frame.

I believe it may be worthwhile to separate transactional considerations
from data access object design. If you need to manage transactions across
multiple database updates, then consolidating all your data access code
into a single DAO is only one way to handle it.
Once you get to the point of needing to manage transactions across multiple
data access objects, it may be worthwile to use an EJB Server (JBoss is
free after all if cost is the issue). Then you can just grab a
UserTransaction to wrap whatever code you want in the web tier and use the
ejb server for managing the transaction details. Then your DAO design
doesn't have to be impacted (as much) by your to manage the transaction.
The other issue is the granularity of the Data Access Object. These can be
fairly coarse-grained and handle updates/transactions across multiple jdbc
connections even in the web tier.
For example, in your example you could have something like:
/*
* handle the debit/credit transaction
*/
UserAccountDAO ua = new UserAccountDAO(userID);
try {
ua.beginDAOManagedTx();
ua.processDebit();
ua.prcessCredit();
ua.commitDAOManagedTx();
} catch (DAOApplicationException e) {
ua.rollbackDAOManagedTx();
}
In this situation the DAO could somehow manually handle the transaction
internally and just throw a DAOApplicationException if problems arise.
I guess what I'm saying is there ain't no holy grail. All you have is
trade-offs between cost, quality and schedule and you do your best.
Different solutions may be better depending on the project and where you're
at...
As they say in Perl, TIMTOWTDI - there's more that one way to do it...

Re: Button pressed
I think (based on at least 3 similar threads) that the best approach is to have a field on your bean named 'action' and figure out later in the action class which was pushed (e.g. form.getAction()) If you have concerns about i18n, there is a work-around for that using the same technique.

referring to the four taglibs - bean, html, logic and template we make use of all. All work very nice. thats the pro.

validation behavior
Hi All:
I just wanted to confirm some behavior I'm seeing with validation and
hopefully get a recommendation or two.
I'd like to have action perform pass either the form values from a post
or the request parameters from a get to a facade. It seems like there's
no way to validate the post but not validate the get. Is this true ?
The body of the perform method would look like:
if(form != null){
// some other code goes here
collection = facade.locateSearchResults(form.getName());
}else{
//other code here
collection = facade.locateSearchResults(request.getParameter(name));
}
There's no reason to validate the request parameters from the get and
there's no association with an html form. Even if I set validate to
false, once I reference the form the validate method executes on the
else condition.
Any way to do this and avoid the unnecessary call to the form bean
validate method ?
Thanks,
Richard

Options Tag, Property Attribute and Accessor Consumption.
Comrades, Here is a Scenario. Let us say we have 2 kinds of value objects extending a base ValueObject. AVo and BVo extend BaseVo and BaseVo has a method getKey() Now I have a collection of AVo's and another collection of BVo's. I want to provide the descriptions of these VO's in a dropdown and capture the key during the process. Both the dropdowns exist in the same form. so the code would be something like. html:select property=key name = ldmGroup indexed=yes html:options collection=ldmGroups property=key labelProperty=formattedDescription/ /html:select So, that takes care of AVo collection in a dropdown. html:select property=key name = twGroup indexed=yes html:options collection=twGroups property=key labelProperty=formattedDescription/ /html:select This is what I have to do to capture BVo's keys. Now I also want to have a drop down of BVo collection but the key[] in formbean is already filled by AVo collection parameters. How can I use the dropdown and capture the BVo's keys? Thanks for your time. hemant

Re: related to: Re: #2 - Use DispatchAction to organize related operations
Rick, Let me mention something. One potential problem with this approach is that by the time the action is called, may be too late. You really need to catch this earlier. I had implemented something along these lines awhile back and soon remembered that the ActionForm is populated and the validate() method is called, all of this before the Action's execute() method is invoked. The question is, do you want to check whether or not the user is logged in after this, or before it. Maybe this is app specific, I'm not sure. It's my opinion, and only an opinion, that you really should be catching this before the action is invoked, if nothing else, for security reasons. What I suggest is to look at the processPreprocess() method in the RequestProcessor and possibly override this to do your checks. It's called for every request and long before ActionForm's are populated and Action's are invoked. The default value is to return true, which allows request processing to continue. What I've done in the past is to override this, check the login, and possibly redirect the user to the login page. If the user's logged in, just return true to continue processing the request.

Ted, I was discussing with James Mitchell about ways to manage a user being logged in and he suggested a way that I really liked where you have a base class perform method handle checking the login status and then call something like a doWork() method that will invoke the work in your subclass Actions (avoiding have to have all your actions handle the loggin check). The question I have is I'm now using a dispatch action class that handles most of the action work. Do I need to go in and modify the base DispatchAction class' perform method in order to get something similar to the above functionality? Or maybe there is an easier way to handle checking login status using a subclass of DispatchAction?

Does struts have a taglib that will provide the functionality for a user to download from an output stream? Thanks for you assistance. You don't really want a tag library for this purpose -- especially if your output is a binary format (which you can't render directly from a JSP). The usual approach is to set up an Action that calls response.setContentType() appropriately, then calls response.getOutputStream() and writes the binary output directly. Finally, you can return null from the Action to indicate (to the controller servlet) that the response has already been created, and that no forwarding is necessary. Alternatively, if your dynamic content is created by some other servlet, you can just set up a forward to that servlet and let it do the work. Or, if it's a static file, just make the context-relative path of that file your forward path, and the container should send the output for you.
