Java Development with Ant
All - I'm proud (and worried about the support e-mails! :) to announce the near-final release of a project demonstrating Ant, XDoclet, Struts, JUnit, Cactus, and Lucene. Its called JavaDevWithAnt as it was written for the book Steve and I co-authored and has been refined during several presentations I've been giving on Ant, XDoclet and Struts. The documentation is in draft stage, and my primary goal is to collect feedback on polishing the documentation (and the application if there are any bugs that surface). The site where I'm hosting the distribution and documentation is: http://www.ehatchersolutions.com/JavaDevWithAnt/ Please let me know if you try it out and have suggestions for improvement, or just to let me know you tried it and hate it or love it, etc. Feedback more than welcome! Direct feedback to me at [EMAIL PROTECTED] Erik p.s. Since this is directed to the Struts lists, here are some hilights: - XDoclet generation of struts-config.xml and validation.xml - Custom XDoclet generation of starter JSP and application properties based on form bean source code - My proudest taglib, LabelTag - shows fields in error and marks required fields with an asterisk. - Use of StrutsTestCase in Cactus mode to test a Struts Action. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Re: Programs become deprecated using nightly build 20011231 and onwards?!
Do just what the message says... compile with deprecation warnings enabled.
If you are building with Ant (and who wouldn't?! :), then your javac task
should have deprecation=true.
Perhaps your build is using a property instead of true though
(deprecation=${build.deprecation}, perhaps), in which case run the build
with -Dpropertyname=true

Re: Form initialization and frames
I have just tackled this very issue. I did try to make my solution extremely generalized, but I haven't decided if/when it will be ready to contribute back. But I will describe its architecture: In our application we have many two-frame pages, top containing criteria, bottom containing results. I have a single action that I call /subsystem/searchSetup.do that forwards to the two-frame JSP page. I have a FramesetData object that is session-scoped. It encapsulates action errors, criteria (a value object representing the form bean from the top frame, typically), and the results (yes, results are stuffed into session, and I'll explain why below). The searchSetup.do action pulls action errors from request scope and puts them into the FramesetData object, and the criteria and results, if present in the request, are put into the FramesetData object also. The FramesetData object is keyed in session-scope by its action mapping path (up to the last forward-slash) - which makes it unique for all such pages in our system. The top-frame's form targets _top and its action performs the search based on the criteria, so that all form validation errors and errors generated from the action get put into request scope as well as the criteria and results (these get keyed with a prefix matching the session key - but only get stored in request scope here). Both the top and bottom frames are .do links, and the top frame's action fetches any drop-down boxes needing populated, fetches the criteria from the FramesetData object and re-populates the form. The bottom frame's action is generalized to simply make a request scoped attribute called results with the results from the FramesetData object. Results are stored in session because I wanted to make sure any errors generated during the creation of those results gets sent to the top frame. The form submit button forwards back to the searchSetup.do action so both frames get recreated when the submit button is pressed. Our application is not designed for heavy use, and when/if the memory eaten by the results in session become an issue it will be addressed, but for now its working nicely. I'm not sure I've covered all the pieces of the framework I've created, but hopefully that is enough food for thought. I'd be interested in hearing how others have tackled this tricky issue. I'm not at all a fan of frames, but this solution made it at least workable to achieve the UI features desired. If there are any questions on this I'd be more than happy to answer them.

I also want the form stored on the request not the session. The problem is that my forward from the Action has to go search.jsp after it populates the form so the form tag on criteria.jsp cannot find the form on the request. It just creates a new instance of the form. I don't want to put it on the session because I don't want to have to worry about cleaning it up off the session. This is a small section of a large app ( a few hundred jsp's ) so I have simplified things a bit. We think we are kind of stuck with frames because as you can probably guess we want the results to show up below the criteria and we want to be able to scroll the results without scrolling the criteria off the screen.

Re: multiple buttons on a form
Yes. The nightly builds contain a patch I submitted, called LookupDispatchAction. It keys off of the use of ApplicationResource messages for button labels and allows reflection to call a different method for each button pressed. The Javadocs explain it in great detail. Even without that base class action, you'll get the button label as a request.getParameter(action) if all your buttons have the name action. But using the button label in an Action greatly munges the View with the Controller and makes things fragile (Java shouldn't break if a button label is changed in the JSP).

In Struts 1.0.1, init() is called if the ActionForm is instantiated by
the JavaServer Page. In Struts 1.0, this only happens when the
ActionForm is instantiated by the ActionServlet. Of course, any default
values assigned to the fields in the ActionForm class itself will be
available in either case. The recommended control flow is to go through
an Action first, and populate the ActionForm there. Populating the
ActionForm from the JSP is a Model 1 strategy.

The reason I'd do it that way is that I imagine the message is a
business
class, and you don't really want you model polluted by extending an
ActionForm. Maybe I've been living in OOAD land too long though ;)
This can trip you up though - at least once I have added the form
element,
added it to the bean, added it to the form bean, and forgetten to do
the
setter in the action :) The way around that is probably a function in
the
form bean that says fill my business class and fill from a business

Re: dynamic images
I'd recommend a custom tag for URL's that get pulled from the DB for a couple of reasons - it probably won't be long before you'll want to offload them from serving directly from the DB, so the URL could switch, scriptlets are *bad* (in a Struts environment). You'll want to direct the URL to a servlet that reads it from the DB and serves up the proper MIME type. We did this in my last extensive Struts endeavor and made the URL's part of a properties file so that for development purposes they could serve straight from a DB accessing servlet, and in a production environment the URL's generated were being served directly from Apache and the images got automatically pulled to static files from the DB when they did not exist in the cache.

Careful with this you're tying your View with your Controller by way of
the button text. If your button text changes, so will your Action code. A
better solution in the case where the button name is the same for all

By the end of the day I'll have a LookupDispatchAction.

[SUBMIT] LookupDispatchAction - how to handle multiple html:submit buttons
As promised earlier today, here is my contribution to the multiple
html:submit button saga (Ted, time to update your FAQ! :)
Here is a breakdown of how to use it:
struts-config.xml segment, note the parameter=action
action path=/test
type=edu.darden.TestAction
name=TestForm
scope=request
input=/test.jsp
validate=true
parameter=action
forward name=success path=/results.jsp/
/action
ApplicationResources.properties segment:
button.add=Add Record
button.delete=Delete Record
TestAction.java (extends LookupDispatchAction) segment, the map is keyed by
ApplicationResources.properties
keys, and the value is the method name you want called (with the same
signature as Action.perform):
protected Map getKeyMethodMap(ActionMapping mapping,
ActionForm form,
HttpServletRequest
request) {
Map map = new HashMap();
map.put(button.add, add);
map.put(button.delete, delete);
return map;
}
public ActionForward add(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
System.out.println( ADD!);
return null;
}
public ActionForward delete(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
System.out.println( DELETE!);
return null;
}
And finally the JSP code segment:
html:form action=/test
html:submit property=action
bean:message key=button.add/
/html:submit
html:submit property=action
bean:message key=button.delete/
/html:submit
/html:form
I recommend the above usage in most cases to cut down on the 'if' statements
and making each unique action clearly defined in separate methods.
But, if there is ever a need to be more general with it, I have provided in
my base class the flexibility to handle dispatching to a single method for
all keys, providing the key to the method. I can only see this being useful
if you have a whole bunch of buttons and there is little difference in the
actions they perform and you only need to do minor logic based on the key.
Here is an example of this, note that if you implement getKeys (and do not
return null) that getKeyMethodMap is not used, so in all but the most crazy
cases would you ever implement both getKeys and getKeyMethodMap. I provided
the mapping, form, and request to these methods just in case someone wanted
to do some dynamic crazy stuff with the array or Map returned from these
methods, but I don't see those parameters being used in most cases.
protected String[] getKeys(ActionMapping mapping,
ActionForm form,
HttpServletRequest request) {
return new String[] {button.add, button.delete };
}
protected ActionForward perform(String key,
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
System.out.println( key = + key);
return null;
}
I am out of town for a long weekend tomorrow, so I wanted to get this done
today and get it out to struts-dev for feedback. I plan on providing Cactus
or Deryl's mock test cases for this (but if anyone wants to beat me to
generating those, feel free!) - for this I really just want to verify that
the correct methods get dispatched with the proper key and that error
handling is dealt with appropriately so Cactus isn't necessary. I based it
loosely off of DispatchAction. It would be nice if my invokeMethod was
actually pushed up to DispatchAction to avoid duplicate code and
DispatchAction refactored to use this helper method.
I believe I might have made this class a little too feature-rich and perhaps
it should be broken into two base classes - one to dispatch via reflection
to a Map specified mapping between key and method, and another to do the
dispatching to an enhanced perform method taking the key. With two separate
base classes the getKeys, getKeyMethodMap and perform could all be made
abstract and remove some likely usage confusion.
My Javadoc comments need some work to encompass both ways of using my base
class, but both methods are documented in this message for now.
I welcome feedback and suggestions on this.

Re: Duplication of Template Files Solution
This was intended to work this way and, like you, did not see it as a possibility in the documentation. Not satisfied with putting things into separate files I searched the e-mail list for template:put and saw an example someone had posted using it in-line and have used that method ever since. Erik - Original Message - From: Darryl Pentz [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, November 01, 2001 4:53 AM Subject: Duplication of Template Files Solution I've discovered quite by accident that the Struts templating framework allows me to eliminate duplication of my JSP pages by simply including the body page inline to the template definition page. By this I mean I combine both pages into one as follows: template:insert ... template:put name=header ... / template:put name=nav ... / template:put name=body ... / ... BODY HTML GOES HERE ... /template:put /template:insert I'd previously enquired on this list how I could eliminate the duplication of the pages where the main body HTML exists in a separate JSP page that is simply referred to from the definition file i.e. template:put name=body content=/blah/blah/body.jsp/. Strangely nobody responded with the above solution so I'm wondering is this simply a side-effect of the PutTag class or Craig, did you intend for it to work this way? I'm quite surprised I haven't seen this technique used in any of the examples. Rather, the duplication is suggested. The new Tiles extension allows the above which prompted me to try it with the Struts template tag library just for grins, and it worked! Is there a problem with doing it inline like I illustrate above? I looked at the source code and I see the PutTag class does extend BodyTagSupport so everything should work fine. So far, the stuff I've played around with seems to work fine with no problems.

Also, the remote scripting API that I created has the capability of short-circuiting responses in a similar manner.

Sure... Remote Scripting.

Re: multibox and reset() ERIK
Jeff,
No, my patch did not fix this particular case. Here is what is happening
in your scenario: checkboxes do not submit a value if they are unchecked,
therefore Struts has no way of knowing of their existence on the original
HTML form and thus does not call any setters. The reset method is where you
implement setting all your checkboxes (and likely other HTML field types) to
their default (false, in your case) value.
My patch was for the case where the ActionForm bean was created by a JSP
page rather than ActionServlet, and reset was not called at that point. In
your case, the ActionForm bean is being created (in the last request you
speak of) by ActionServlet, so reset should be called - this is all assuming
you are going through a Struts action for that request.
My patch has been committed to Struts CVS, so its available in the nightly
builds (I presume, unless those builds are running on a different branch or
something).

Re: multibox and reset() ERIK
The better way is just what was mentioned set your values to null
(false?) in the reset method. But if you are using Struts 1.0 and not a
more recent build, also setting them in the constructor or initial values
when defined is a good idea to default them in the case you are navigating
directly to the JSP page rather than going through a Struts action to get to
the JSP page.
So more succintly, initialize values in reset and that should fix the issue
you described. Did you try that?

I am having trouble resetting a StringArray that is connected to a
html:multibox-tag.
HTML-Example:
html:form action=/map method=GET
html:multibox value=parking property=layer/
html:multibox value=petrol property=layer/
html:image property=layers page=/img/update.gif/
/html:form
Corresponding ActionForm:
public class MapForm extends ActionForm {
private String[] _on = new String[0];
public void reset() {
_on = new String[0];
}
public void setLayer(String in) {
_on = in;
}
public String[] getLayer() {
return _on;
}
}
The Manual told me to use the reset()-method to set The Array to the
length 0, but reset() is never called.

Re: re-Logon after session timeout
I'm accomplishing this very thing using Resin's Servlet 2.3 Filter support. The filter determines the user is not logged in, saves the requesting URI in a session attribute, and forwards to the login page. The login action checks for the existence of the session attribute with the saved URI and forwards to that upon a successful login. I'm sure it could be done in a Servlet 2.2 environment also, but would require more effort.

Re: newbie question - confused
Look at the generated HTML of logon.jsp you'll see that it submits to logon.do. html:form looks up the action mapping to determine which form bean to use and generates the form tag with the appropriate action .do extension automatically. Erik - Original Message - From: Jose Correia [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, September 06, 2001 7:22 AM Subject: newbie question - confused Hi all I'm a bit confused with the Struts example (the one that comes with struts1.0.jar). I'm trying to determine at which point does the .do come in to being. Facts first: 1. index.jsp shows: html:link page=/logon.jspbean:message key=index.logon//html:link/li i.e calls the file logon.jsp 2. logon.jsp defines an action form: html:form action=/logon focus=username 3. struts-config.xml defines an action mapping: actionpath=/logon type=org.apache.struts.webapp.example.LogonAction name=logonForm scope=request input=/logon.jsp /action Now the tour guide under the heading LogonAction.java says: The initial JSP submits its form to logon.do. If you check the servlet mappings in the example's web.xml you will see that requests for *.do files are directed to the Struts action servlet (an instance of ActionServlet). In the example, the ActionServlet refers to struts-config.xml for its own mappings (among other things), which is where we find the reference to logon.do: To my knowledge the initial jsp (logon.jsp right?) is submitting a form to the action servlet which matches the action value in html:form action=/logon ... to the action mapping path actionpath=/logon ... correct? i.e. /logon matches /logon. I am aware that web.xml defines a servlet-mapping for *.do but thats only if the user or the system makes a request for a .do file right? Now in the above case a request is being sent first to logon.jsp from index.jsp. Then the action form in logon.jsp if there are errors it calls: return (new ActionForward(mapping.getInput())); where the input is /logon.jsp as defined above in the action mapping. Otherwise it forwards it to mainmenu.jsp. Now where does the .do come in? Is it internal to struts?

Re: bean:define, bean:write
Matt,
My implementation is pretty domain specific though (our image tag requires a
parent tag to set up some context), so my actual code is not generalizable,
but here's the essence of it (cutting and pasting, and trimming down to the
essentials):
import org.apache.struts.taglib.html.ImgTag;
public class ImageImgTag extends ImgTag {
protected String src() throws JspException {
String path = lookupPath(pageContext.getRequest(), src);
return path;
}
}
The implementation of lookupPath is, of course, left as an exercise to the
reader, but in our case it looks up a URI (or URL fragment) from a
properties file, and using java.text.MessageFormat replaces the appropriate
pieces in that string and returns it. The reason the request is passed in
is so that the URL can be relatively specified to the app. context(i.e.
prefixed with request.getContextPath()) or absolutely specified (depending
on whether it starts with a forward-slash or not. In our case we aren't
using the ImgTag provided src variable, I just faked that for the above
example, but that would be one way to pass in the image filename (with no
path, I presume) and have that appended to a looked-up URL prefix. We use
this feature to serve images from our application server (which gets them
from the DB as BLOB's) or from statically generated files using Apache
directly, and at configuration time we can specify where images get served
from.

Re: Concurrency and Custom JSP tags
Quoting from Geary's Advanced JavaServer Pages book, p. 14: Because servlet containers can reuse tag handlers, you must be diligent about implementing the release method and careful about instantiating resources in doStartTag [rather in the tags constructor] So the 'release' method is the key. You'll notice that the Struts tags use the release method to clear their resources. Tag instances are not used simultaneously, but released for re-use after they are done, so member variables are ok, but care must be taken not to allow them to carry over to future uses. I highly recommend Geary's book for all Struts power users and developers, especially in regards to custom tag development. Erik - Original Message - From: Bill Clinton [EMAIL PROTECTED] To: struts [EMAIL PROTECTED] Sent: Wednesday, September 05, 2001 3:42 PM Subject: Concurrency and Custom JSP tags Hello, I have been writing my own custom jsp tags, and have recently noticed that member properties of tags seem to be retained after the tag is complete. For example, lets say you have a tag that has an optional attribute called message, and the tag is designed to print this attribute if it is passed. If you call this tag and pass hello as the attribute message on one page, then call this tag on another page without passing the attribute, it will still be set to hello. This functions much like a servlet, which is multi-threaded but retains the values for member variables across different requests. I think most servlet programmers realize this and stay away from using non-static member variables. But it seems to me that custom JSP tag design encourages the use of attributes, which seems to be potentially very dangerous in an environment with a high volume of requests. I would like to know if anyone knows of any good links where concurrency issues in custom jsp tags are discussed more in depth. Also, I am curious to know if anyone has encountered any problems like this with the Struts tags. For example, if I set an onmouseover for a html:checkbox tag, do I have to worry about this attribute showing up in a html:checkbox tag called from a different page if both pages are loaded by different users at the same time?

ImgTag, encodeURL, and jsessionid
I hadn't gotten any response on struts-dev yet, so I thought I'd try struts-user out after seeing a related message about URL rewriting.. I have a custom subclass of ImgTag that overrides the src() method to provide a custom URL depending on some flags in our system (in order to offload image serving from the application server by hosting them off Apache directly).In development environments the URL's returned are within the application context. In production environments, the URL's returned are absolute http://; and not within the application context. All URL's end up getting rewritten with the ;jsessionid initially, but it doesn't make sense to have URL's outside the app. context rewritten that way. Has anyone encountered this problem and resolved it?In ImgTag the HttpServletRequest.encodeURL method is called which where that is happening, but why?Does it blindly rewrite all URL's?Or should it only rewrite URL's within its own application context as seems logical to me? Is it my app. server (Resin 2.0) that is doing the wrong thing? And if encodeURL is supposed to blindly rewrite all URL's, shouldn't we make some kind of switch to either turn on/off the URL rewriting in ImgTag? For now we are handling it by having Apache strip off the ;jsessionid before those requests for images in our image cache. Thanks, Erik

Subject: Access to HttpServletRequest within ActionForm
Hi,
is there a way of getting access within an ActionForm to the request that
caused the ActionServlet using this ActionForm?
Something like:
public class MyActionForm extends ActionForm
{
public MyActionForm
{
super();
HttpServletRequest request = getItSomeHow();
...
}
...
}
When the ActionForm is getting created, I need access to some objects that
are placed within the current session.
Depending on those values, the ActionForm shall be set up differently.
Thanks in advance,
Holger
Re: How to turn off validation momentarily
In struts-config you can specify that validation won't occur on a per-action basis like this: action path=/someaction type=com.whatever.SomeAction scope=request name=SomeForm input=some.jsp validate=false forward name=receiptpath=another.jsp / /action Does that help?

I've tried placing a mapping.setValidation(false) in various places in my edit and save actions (a la struts-example). Basically, I do not want to validate a record that I'm presenting to the user in order to confirm a delete, but the form is set up for validation, so that gets executed too. But we're deleting, so why bother? Thanks in advance for any tips. -- Tom Miller Miller Associates, Inc. [EMAIL PROTECTED] 641.469.3535 Phone 413.581.6326 FAX
