RE: [OT] Dealer Locator / Zip Code Lookup
Basically, yes (I think). What I've seen are site like homedepot.com where you can pull up a store locator, enter a zip code, and it will return all of the stores within a set radius around the zip code. I've foud a commercial product called "Bullseye ZipCode Locator" that is java based (about $1000 for the lite version), but like I said, I'm cheap Jerry Jalenak Development Manager, Web Publishing LabOne, Inc. 10101 Renner Blvd. Lenexa, KS 66219 (913) 577-1496 [EMAIL PROTECTED] > -Original Message- > From: Martin Gainty [mailto:[EMAIL PROTECTED] > Sent: Thursday, March 18, 2004 12:33 PM > To: Struts Users Mailing List > Subject: Re: [OT] Dealer Locator / Zip Code Lookup > > > The problem is that ZipCode roughly corresponds to GPS Coordinates > The algorithm you will need to deploy would be to locate a > dealer by either > Zip Code > GPS Coordinates > After you have extracted selected record items from the DB > you can then > populate a Tag such as selectmany_listbox > Is this what you are looking for? > Martin Gainty > - Original Message - > From: "Jerry Jalenak" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Thursday, March 18, 2004 11:51 AM > Subject: [OT] Dealer Locator / Zip Code Lookup > > > > All, > > > > i'm looking for (hopefully) an open-source product that > will allow me to > do > > a 'dealer locator' type of function - one where I enter a > zip code and a > > radius, and I get back a list of 'dealer' within that > radius.

[OT] Dealer Locator / Zip Code Lookup
All, i'm looking for (hopefully) an open-source product that will allow me to do a 'dealer locator' type of function - one where I enter a zip code and a radius, and I get back a list of 'dealer' within that radius. If there isn't an open-source product (yes, I'm cheap), can anyone recommend a commercial product? Thanks.

RE: Best way to handle big search results..
Hasn't been a problem so far 8-) When i first designed this system, I went with an approach to do my lookup directly from the db. Turned out that, with these large account clients, the SQL call was coming back fairly quickly, but it was taking significant time to run through the records and apply various filters that are available to the user (date range, previously viewed, sub-set, etc.) So I went back to the drawing board, wrote this second servlet to maintain some in-memory data structures (basically maps-in-maps), and dramatically sped up the whole app. The only remaining issue is this one - where I am returning a couple of thousand accounts and several thousand detail records I may have to end up re-negogitaing this one business requirement.

RE: Best way to handle big search results..
Unfortunately, the business gets to dictate this one, and they maintain that these large clients need to ability to view up to 90 days worth of data. I agree with you that this is logistically impossible, but since the business requirements state that it must be so, my QC group is testing it and saying that it fails. If it fails, it's got to be fixed.....

RE: Best way to handle big search results..
But. I'm already doing paging. Each independant account table only returns the first 10 detail records; everything is available by paging through the next 'n' pages. For example, one of my clients has access to almost 8900 accounts. Of these accounts, there are about 3500 with reported data in the past 90 days. In the past month alone, these 3500 accounts have almost 48000 detail records. So I'm returning (probably not all 3500 accounts, but a good majority of 'em) say 2000 tables, with potentially 10 detail records per table. Each table has seven columns, so just for the tables I'm returning about 320,000 lines of html. I'm really starting to think this is a client side rendering issue - the browser simply can't process the number of lines of html that I'm pushing it.

RE: Best way to handle big search results..
Mark, Let me give you some background first. On any given day I will be reporting on about 80,000 accounts with over 300,000 detail records available for the past 90 days. My clients are using this data to determine employment elgibility, etc. The majority of these clients are individual employers that might have between 1 and 100 accounts. These are no problem. The 'problem' clients are organizations that handle this type of work for multiple employers on a contract basis. These clients can and do have several thousand accounts that could *potentially* have data that needs to be reported. The approach I took was to write a separate servlet that wakes up every hours, re-sweeps the account code table, re-sweeps the data table, reconciles these into a set of nested maps, and places it into application scope. Part of this process throws out any account that doesn't have data to be reported, otherwise I'd be trying to handle 200,000 accounts. Based on the account and type of data the user can 'see', they are presented a list of accounts where they can pick one, many, or all. The application then accesses the map structure in application scope, extracts the appropriate data based on account, date range, etc., and returns a set of tables to the user. These table are required to be independantly sortable, pagable, etc. Again, for up to 100 or so accounts, this is extremely fast. It just goes down the toilet once I start getting over about 500 accounts.

Jacob / Geeta - Thanks for the responses. The business requires that each account / detail record set be placed in an independantly pagable/sortable table, so I'm using the taglib to handle this. For relatively small numbers (say up to a 100 accounts or so) the performance is really pretty good. I'd like to be able to restrict the date range that a user can specify, but again, business requirement states that 'the user must be able to browse upto 90 days worth of data'. I've tried to explain that, for some of these large clients this simply isn't going to work. I was hoping (8-) ) that there was a setting in Tomcat that I may have missed (I've already set up Tomcat as a 'production' environment). I don't know if it makes a difference, but I have yet to move to the EL tags - I'm still using the old Struts taglibs for things like , etc. Has anyone benchmarked the performance between these two approaches?

RE: Best way to handle big search results..
In my application I often return large amounts of data - for instance, a single user may have access to as many as 8500 accounts; each account may have several hundred detail records associated with it. I've solved my initial problem of being able to return thousands of records (for instance, I can return almost 48,000 detail records in a little under 5 seconds), but the problem I have now is that it takes FOREVER for the jsp to render. I mean, I've waited over an hour for this thing to complete. Does anyone have any tips on improving / optimizing the performance of a compiled JSP? I'm using Tomcat 5.0.18 Stable with J2SDK 1.4.1_02 Thanks!

RE: Extra Lines in Compiled JSP
Thanks to everyone and for their comments. What I was seeing were several blank lines at the top of my rendered page - lines that I could not account for in the html code. After scratching my head for a few days, it occurred to me that the number of blank lines being rendered were the same number of lines as my <% taglib %>'s - in this case seven lines. Opening up the compiled JSP I found where it was putting seven out.write() statements. I know the browser should ignore successive white space like this, but in my case it wasn't (this is an IE 6 browser). We're running Tomcat 5.0.18 and J2SDK 1.4.2.

[OT] Animated .GIF's
I've been trying to find an answer to this via google for awhile now, but can't seem to find any info on my problem. I'm hoping someone might be able to shed some light on this for me. I've got a simple animated .gif (Loading Data... kind of thing) that I need to display whenever my submit button is clicked. Until the submit button is clicked though, I hide the image When the user clicks the submit button, I use javascript to change the style to "display:inline". The image appears, but the animation doesn't seem to work. If I load the image without the "display:none" or even with "display:inline", the animation works fine. It only seems to fail when the initial display setting is 'none'. What gives? Am I just missing an additional setting? Thanks.

RE: Extra Lines in Compiled JSP
Thanks for the reply. I strung out the taglib defn's and reduced the number
of out.writes from seven to one. It's better, but still not perfect. Seems
like the jsp compiler should be smart enough to recognize that it doesn't
need to generate anything for these kinds of lines.

Extra Lines in Compiled JSP
Hi All,
I should know how to fix this, but am at a loss. At the top of my JSP I
have the following lines:
<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean"; prefix="bean" %>
<%@ taglib uri="/display" prefix="display" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html"; prefix="html" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-nested";
prefix="nested" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-tiles"; prefix="tiles"
%>
<%@ page language="java" %>
<%@ page contentType="text/html; charset=UTF-8" %>
When I look at the compiled JSP, there are seven blank lines (i.e.
out.write("\r\n"); ). Is there anyway to have the JSP compiler (were
running Tomcat 5.0.18 Stable) NOT generate these lines? I guess they come
from the <% %> sources lines, but it really screws up my generated HTML
code
Thanks!

[Validator] Custom Validator Fails to Return to JSP
I've used the 'comparing two fields' example from Validator for a while now without any problem. When I brought down the 20040106 nightly build, I noticed that several methods had been deprecated, so I dutifully changed things over: From: public static boolean comparePasswords(Object _object, ValidatorAction _va, Field _field, ActionErrors _errors, HttpServletRequest _request) _errors.add(_field.getKey(), Resources.getActionError(_request, _va, _field)); To: public static boolean comparePasswords(Object _object, ValidatorAction _va, Field _field, ActionMessages _messages, HttpServletRequest _request) _messages.add(_field.getKey(), Resources.getActionMessage(_request, _va, _field)); If I continue to use the 'From' form (with ActionErrors), I get NPE's on the _errors.add; if I use the 'To' form, everything seems to work but I don't go back to my JSP; rather, it appears to be returning null as I end up with a blank page. Also, before anyone asks, I do change the validator.xml to the appropriate methodParms: From: To: I can't seem to find a bug report on this, and there doesn't seem to be much more information on the changes on the website. Can someone shed some light on this? Thanks! PS - I would go grab a more current nightly build, but it appears that the nightlies are failing. Has anyone looked at this?

[DisplayTag] Use of ID= Parameter
All, I'm in the process of implementing the new taglib, and am really excited about the ability to have multiple, independent, tables on the same page. In order to make this work, though, the ID= parameter for each table has to be different. This is where I'm running into problems. I've got my inside of a so I can generate 1-n tables - this works fine. However, when I try to vary the ID= parameter, I get ClassCastExceptions in org.displaytag.tags.TableTagExtraInfo on the following line: Object tagId = data.getAttributeString(TagAttributeInfo.ID); I've tried to define a page-scope variable and include it in a small chunk of scriptlet code, but I just can't seem to get around this.

Using tag with nested beans
I'm trying to get the tag library to work with my nested bean structure without much luck, and after screwing around with this for the past three days, I'm ready to throw in the towel. If anyone can see what it is I'm doing wrong, I'd appreciate it. Basically I've got the following (currently): This works fine, as I get the values for item1, item2, etc. I now need to replace the last with a tag with appropriate 's. I've tried several things, including: I've also tried to set a page-scope object on the 'list2' iterate: Whatever I try I am consistently getting a JSP exception thrown of ERROR 01/19/2004:12:07:51 - Error looking up property "specimenId" in object type "java.lang.String" Exception: [.LookupUtil] Error looking up property "specimenId" in object type "java.lang.String" Cause: Unknown property 'specimenId' from org.displaytag.util.LookupUtil.getBeanProperty(LookupUtil.java:210) at org.displaytag.model.Column.getValue(Column.java:93) at org.displaytag.model.Column.createChoppedAndLinkedValue(Column.java:144) at org.displaytag.model.Column.getOpenTag(Column.java:120) at org.displaytag.tags.TableTag.getHTMLData(TableTag.java:1136) at org.displaytag.tags.TableTag.doEndTag(TableTag.java:847) Help!

Craig - Thanks for the response. One last question - during the time period where the getServletContext().setAttribute() is executing in Servlet_1, is there any concern about collision with an access from Servlet_2 (Struts)? I guess I'm unsure whether the setAttribute() method is synchronized or not (the javadoc doesn't say.) Thanks!

[OT] Synchronized access to application-scoped object
Holiday Greetings to All! Quick design question - Is it possible to synchronize an application-scoped object between two servlets within the same web application? I have a servlet that I have written that maintains a List object that is stored in application scope. This servlet basically creates a new List, then replaces the existing one (uses the same name for the object). My second servlet (Struts) simply accesses this List in a read-only fashion - no updates. I can write a basic spin-lock type of mechanism to ensure that my Actions do not try to access this List while my first servlet is replacing the object, but I'm wondering if there is an easier approach, possibly using a synchronized block using the application object Comments?

RE: [OT] HTML Select box
<[EMAIL PROTECTED] /> Thanks to everyone who responded. Let me clarify on this: If I set my to use a size=?? and set multiple="true", I can indeed select multiple options. The problem is, when I set the size parameter to something like 10, I end up with a 10 items displayed in a rather large box (I know, this is how it works!). What I would rather have (and maybe I simply can't do it) is to have a single line displayed with a 'down arrow' (like what you would get without using the multiple="true" and with size="1"). When you clicked on the down arrow, the box would expand downward, and the user would then be able to select multiple options by holding down the CTRL key. Submitting the selection would send all of the selected options to my Action. Does this make any more sense?

[OT] HTML Select box
Hi All, Can't seem to find a way to do this, even though I've seen it done (I think). What I need is a HTML select box where the size parameter=1 (so I get a true drop-down, not a scrolling box) AND the ability to select multiple options within the select box. Right now if I set the multiple parameter I get a scrolling box.

RE: [OT] RE: File Download?
Jacob,
Thanks for the help. I need to review the business requirements (again!)
and make sure that we are going down the right path. I'm not sure a .zip
file will meet the clients needs; I'm also not sure that requiring them to
download each file individually will work for them either.
Thanks again.

RE: [OT] RE: File Download?
Jacob -
Knew it had to be something easy 8-)
Second question - One of my requirements is that my users need to ability to
select multiple files from a list of available files. I need to be able to
store each selected file individually on their hard drive. Using your
approach, can I flush the response buffer between each file in order to do
this? Something along these lines:
get the requested filename(s)
while (more filenames)
{
retrieve the file
set the content type
set the header
flush the response buffer (leaving the connection open)
}
Thanks!

RE: [OT] Stress Test
David, Nothing. Nada. Zip. ZIlch. The logs show basically no response; from the client perspective the web app simply stops responding. I suspect I've either got a memory leak, or a database connectivity issue. Hopefully I can stress test this thing enough today to identify where in the code it fails. Once I know where it fails I should be able to fix it.

Hi All, I've got a problem with my current web app where it stops responding after about 6 hours. I need to set up a test environment and simulate multiple logon's so I can trap my way through the code and figure out where it is failing. I think there is a tool available that can be used to do this - HTTPerf (I think), but I'm not sure if this will do what I want. Does anyone have any experience with this? Thanks.

RE: [OT - Design] Needing Fast Access to 300,000 Records
Vic - This is still in the design stage, so I don't have a SQL statement to provide. I'm looking for the best approach to handling what is essentially a table lookup where I need two keys (BILLING_ACCOUNT and ACCOUNT_CODE) The scenario is this: When one of my clients logs on to the webapp, the app determines the BILLING_ACCOUNTs the client has assigned, then explodes the BILLING_ACCOUNTs into the composite ACCOUNT_CODES. As an example, I've got one client with 54 BILLING_ACCOUNTs; these explode to over 30,000 ACCOUNT_CODES. I am trying to eliminate 30,000 db calls to get the account information - that's why I'm looking to pre-load the table(s) in a plug-in and access everything in memory. Make sense?

[OT - Design] Needing Fast Access to 300,000 Records
Hi All - I've been trying to figure out a good way of handling something, and just can't quite seem to get a grip on the best approach. Here's what I've got: Two database tables - Table 1 has a BILLING_CODE and an ACCOUNT_CODE. Table 2 has the ACCOUNT_CODE and other account information (name, address, etc.) The tables are linked by ACCOUNT_CODE. Table 1: Table 2: BILLING_CODEACCOUNT_CODE ACCOUNT_CODENAMEADDRESS ... 1234ABC1 ABC1blahblah 1234ABC2 ABC2blahblah 1234ABC3 ABC3blahblah 5678DEF1 DEF1blahblah 5678DEF2 DEF2blahblah I need to be able to rapidly access the information in table 2 either through the BILLING_CODE, or directly through the ACCOUNT_CODE. I can create a POJO containing the BILLING_CODE and a List object to hold a second POJO for the table 2 info. Or I can use a Map. Either way doesn't give me a good method of accessing the table 2 information based on ACCOUNT_CODE. Two other bits of info - the combined number of records exceeds 300,000, so I have a scaling issue. Second, I'd like to load everything in a plug-in using iBatis dbLayer and store it in application scope (to eliminate db calls as the webapp is used.) Does anyone have any experience in handling something like this? How did you do it? Thanks...

RE: [OT - JavaScript] Setting value on a
Melissa / James - Thanks for the replies. It does have something to do with setting the 'disabled' attribute to 'true'. Unfortunately, per W3C spec, the tag doesn't support a 'readonly' attribute, only a 'disabled' attribute. Do I need to disable the options? or is there a better way to not allow a user to select a different option?

[OT - JavaScript] Setting value on a
Been screwing around with this all morning, and can't seem to find an answer. I've got two radio buttons on a form. If the user clicks the second radio button, I need to force the value of a following to a specific value, and disable the select. So, using JavaScript, on my radio button I fire an onclick event that run a real simple javascript function. In this function I've tried using document.formName.selectVar.value = // is accepted, but the isn't passed to my form bean document.formName.selectVar.option[0].selected = true // ditto document.formName.selectVar.option[0].value = // ditto document.formName.selectVar.option[0].isSelected = true // ditto JavaScript seems to accept all of these formats, but the setter method in my form bean for 'selectVar' is never getting called. This is going to be a 'Doh!' moment, but how do I do this? TIA!

[OT] JSTL Taglib Definition in WEB.XML
All, After reading the JSTL docs on the Jakarta web site, and googling for about an hour, I can't seem to find a answer. So, for all of you JSTL guru's out there, here's the question: In WEB.XML, do I need to specify the '-rt' taglibs? In other words, do I need both of these, or only one or 'em? /c-rt /WEB-INF/tld/c-rt.tld /c /WEB-INF/tld/c.tld ... etc etc etc ... Thanks!

RE: YASJR, Part Duex
Let only the sheer number of struts user who downloaded the release candidates prior to the final. If there was malicious code in Struts, it wouldn't have taken long for several users to have identified it, and screamed loudly on this list and on the developers list. I would rather use a product that has had a world-wide community of people looking at, than a closed product (i.e. ANYTHING from M$). Look at the constant stream of security flaws in Windoze - don't you think that if a several thousand users could dig through Windoze, we might find more than a few of these BEFORE they are exploited by those with less than honorable intentions? my $.02 Jerry Jalenak Team Lead, Web Publishing LabOne, Inc. 10101 Renner Blvd. Lenexa, KS 66219 (913) 577-1496 [EMAIL PROTECTED] > -Original Message- > From: Steve Raeburn [mailto:[EMAIL PROTECTED] > Sent: Thursday, September 11, 2003 11:58 AM > To: Struts Users Mailing List > Subject: RE: YASJR, Part Duex > > > Well I would say that software the passed QA containing > malicious code was > faulty! > > My point was that your company should trust you to judge the > quality of the > code you're working with - wherever it comes from - and that > you should have > a reasonably high degree of confidence in Struts code because: > > 1) You can review the code yourself. > 2) Thousands of other developers also review the changes. > 3) The committers review changes. > 4) Only a small number of people actually have commit access. > > Good luck with your project! > > Steve > > > > -Original Message- > > From: Gregory F.

RE: Converting a ResultSet to a List of POJOs
Matt -
After reading your post here and on the iBatis forum on SF, I thought I'd
run some tests on my authentication process as well. I'm using a static
block to initially read in the sql-map.xml file, and am using the
sqlMap.executeQueryForObject method w/o a 'true' DAO (calling the method
directly from my business model). Here's what I found:
first call to initialize (read) the sql-map.xml file: .688
first call to executeQueryForObject:6.485
(ouch!)
subsequent calls to executeQueryForObject: .031 - .032
(tested multiple times)
I think this agrees with what you saw, and with what Clinton indicated - the
first call is *really* slow due to the additional initialization that
occurs. Once that is complete, iBatis seems to be a fast as native JDBC...

[Validator] E-Mail Verification
Is there a published specification on e-mail addresses? The reason I ask is that we are using the 'email' validator, and it's accepting as valid e-mail addresses such as 'u-+-+%^_/[EMAIL PROTECTED]'. I didn't think Validator would accept these, but apparently is it. If there's not an established spec for e-mail addresses, then I would assume that anything goes Comments?

RE: J2EE IDE
I agree with David. Originally we were using Netbeans, but quickly dropped it due to stability issues (java.lang.Exceptions right in the middle of editing a file, for example.) We switched over to Eclipse 1.0; this version had some odd behaviour at times, but didn't crash like Netbeans. Version 2 and now 2.1 of Eclipse is super stable; I'm often on it for 8 or 10 hours a day, and have never had a crash. Boot time is much faster than version 1. I'm not sure about the refresh time - do you mean you are running your Ant build script every time? We don't use the built-in Ant support (actually don't use Ant at all), but the compile time when we modify a resource is blindly fast. I've never had to wait on a project re-build - never. +1 for Eclipse.

RE: throwing null servlet exception
David, That's basically what I thought. However, when I change this errors.add(ActionErrors.GLOBAL_ERROR, new ActionError((String) ee.getErrorKey())); to this errors.add(ActionErrors.GLOBAL_ERROR, new ActionMessage((String) ee.getErrorKey())); my JSP blows up on the statement (gives me a 'null' servlet exception.) Since you've been working on making all this play nice, do I just need to pull down a more recent nightly (I'm using 8/14 currently...) Thanks!

RE: throwing null servlet exception
Partially answering my own question - Changing back to use ActionError (and ignoring the deprecation messages that Eclipse spits out), I can get my messages to work. Obviously the problem is that I am mixing ActionErrors and ActionMessage. What is the preferred method? It looks like ActionError has already been deprecated; does this mean we should be using ActionMessages/ActionMessage for returning errors? TIA!

throwing null servlet exception
Using the nightly build from 8/14, I'm now getting a null servlet exception on an statement. I've also had to change from using ActionError to ActionMessage since it appears that ActionError has been deprecated in 1.2.1. I've tried changing everything over to use ActionMessages, ActionMessage, and , but still am getting the null servlet exception. Has anyone else come across this?

Just curious - how do most of you return errors from your business model? Do you simply return an integer value (-1, 0. 99?) and then interpret it in the action? Or do you return a error string that maps to something in ApplicationResources? Any other techniques?

Erik, David, and Mike - Thanks for the replies - interesting to note that all three of you suggested basically the same answer, that of using the exception mechanism. When implementing this, do you code individual, specific exception handlers (i.e. InvalidUserException, etc), or do you have a generic handler that you can pass a 'cause' back through? Thanks.

I've started looking at the Type-Safe Enum pattern; except for providing a 'type-safe' construct in which to code return status, it doesn't look like it does much more for me than returning a simple integer. I still end up in the action with a whole series of if-else-else-else statements (and maybe I just need to get over my 'ugh' factor and move on :-) I do like the idea of being able to code a method as a status and actually do something, though.

I'm trying to find a 'best > practice' on how to do this I (and probably the others who responded) thought you were asking for ways for the business/domain model to indicate to the controller/Struts layer what kind of error it [the domain layer] has encountered. This is when I suggested using exceptions, instead of returning any kind of error code whatsoever. The reason why Java has exceptions is because the problem with returning error codes is that, usually this results in a big chunk of code that tests this return code, such as a sequence of if/else statements, or a big switch statement. This is fine in C, which doesn't have Java's try/catch/finally exceptions, because you *need* to make sure that the data returned from an operation is sane. However, with try/catch/finally, you can just put your code into a try block and catch any exceptions that get thrown in the process of trying to execute that code. So instead of testing the return code from an operation for sanity, the language lets you interrupt the operation altogether when there is a problem, and your exception handler can step in to clean up, log the error into a logfile, and set things straight. My last post, which was intended to clarify my position, basically reiterates the fact that this is for exceptional circumstances only -- not a good way to control the flow of logic in your application. In answer to your more recent question above, "when a business model needs to return a status (not an exceptional condition (i.e. SQLException)), what is the 'best practice' for doing this?" I don't really find myself needing to test the status of an operation. Usually an operation either returns the result I'm looking for, or it fails altogether (and goes to a catch block). I just use the value that the operation gave me, such as echoing it out to the user or performing a calculation with the result. However, I can understand that there are plenty of times when an operation can return a variety of different results, and you want to do something different with each one. That sounds like what you've described in this most recent email. What you're asking about is an "enumeration". There's a number of different ways to implement an enumeration -- some people say just return a different String, and then you can analyze the String in your code to decide what to do with it. Others suggest using integer status codes, which is the sort of thing you'd expect in a C program (where the concept of an enumeration is supported by a language keyword). I guess Java 1.5 is supposed to feature some sort of enum support as well, though I don't know much about it. My favorite implementation of an enumeration is Josh Bloch's "Type-Safe Enum" design pattern. You can lo
RE: [OT] Determining Class Type of Action
No, it's not. Poor typing on my part 8-)
I've worked around my problem by getting the name (.getName()) and doing a
String comparison. Not real pretty, but it works. I'd rather check to see
if it is an instance of DispatchAction rather than checking to see if it is
'org.apache.struts.actions.DispatchAction'.

[OT] Determining Class Type of Action
I am extracting the class type from an Action:
Class c = Class.forName(mapping.getType());
I can then 'chase' the class chain backwards:
boolean isDispatchAction = false;
while(!isDispatchAction)
{
c = c.getSuperClass();
if (c.isInstance(org.apache.struts.actions.DispatchAction)
{
isDispatchAction = true;
}
}
The 'if' statement comparison is never true. I've printed out the value of
'c' on each iteration through the loop, and can see when it is
'org.apache.struts.actions.DispatchAction', but my isDispatchAction boolean
never gets set to true.
What's the right way to do this?

+1 - Validator works. I started using it wy back in the pre-RC1 days. Everytime that Validator hasn't worked for me, I've found that it was due to a screw up on my part (usually something in the validation.xml file).

While I haven't found any major bugs (at least ones that haven't already been reported), Validator does have its quirks - you have got to get the validation.xml file right or else it just flat won't work.

RE: [OT - Slightly] Returning Error Status from Business Layer
Erik,
I'm starting to see it now (I think). Let me describe what I am trying to
solve...
I have an order screen where a client can, well, order one or more items.
The struts action picks up the item number and hands it off to a business
class. The business class goes to the database (DAO), and based on what
comes back, either returns a JavaBean containing the item information, or a
status indicating out of stock, no longer carried, etc. Since I can only
return one object from a method, I either end up adding a 'status' field to
the JavaBean, or I end up returning a type of 'Object' and checking in the
action to see if it is a type of JavaBean or not - if not, I cast it to an
Integer (or String) object, and figure out what happened. If it is a type
of JavaBean, then I go merrily on my way. The other option is to code
unique exceptions and throw OutOfStockException (for example) and have the
action 'catch' it and handle it. Frankly, I don't like any of these
options, but can't seem to find any other options.
I have a 'Constant' class where I put values that are used for storing
objects in an HttpSession. Should these be re-coded to use the TypeSafe
Enum pattern?
Thanks for your input on this - I do appreciate it.

Right, this doesn't work in every case of the type-safe enum, but
sometimes you can get rid of a series of if/then/else statements with a
method invocation. Here's a very very simplified example:
public class Status {
// instance members
private String code;
private Status(String code) {
this.code = code;
}
public boolean equals(Object o) {
return this.code.equals(Object o);
}
public int hashCode() {
return this.code.hashCode();
}
// static members
// this stub method is intended to be overridden
// in anonymous subclasses of Status, so it just
// throws an exception unless it's overridden.
public void printStatus() {
throw new UnsupportedOperationException();
}
public static Status GOOD = new Status("good") {
public void printStatus() {
System.out.println("You done good! Live long and prosper.");
}
};
public static Status BAD = new Status("bad") {
public void printStatus() {
System.out.println("You done bad! No soup for you.");
}
};
}
Now, if you simply used an integer for the return code of an operation
(say, GOOD = 1, and BAD = 0), it's a lot less typing than the above.
But there's no type safety, that is to say, it's possible that by some
accident, your application could return a status code of 2. This is can
be a very difficult bug to spot in some contexts. Even more so when
you're releasing your code as a library for others to make use of. So
the type-safe enum pattern makes sure that only GOOD and BAD can be used
(there's no way to sneak in an extra static member into the class [that
I know of]). Of course, if you find that you need to add additional
status codes, you can just code them into the class and recompile.
The second benefit is the encapsulation of enumeration-specific behavior
I've mentioned before, where you can simply dispatch a message to the
enumeration rather than test its value, because each instance of the
Status has its own "printStatus" behavior. This doesn't *always* work
in every circumstance (not every enumeration is this simple), but it's
generally worked for me.
In an integer-based enumeration, you need if/else tests to decide what
to do, or switch statements:
int myStatus = performSomeOperation();
if (myStatus == 0) {
System.out.println("You been bad!...");
... do some other stuff here
}
else if (myStatus == 1) {
System.out.println("You been good!...");
... do some other stuff her

RE: [OT - Slightly] Returning Error Status from Business Layer

I think it's just that one of the cool things about Java over PHP or C is that we have exceptions, and we don't have to test return values -- we can just write code that assumes that an exception was not thrown, but if one -is- thrown, we can catch it and deal with it. (Within limits -- obviously it's not just as simple as assuming that no exceptions are thrown) > When > implementing this, do you code individual, specific exception handlers (i.e. > InvalidUserException, etc), or do you have a generic handler that you can > pass a 'cause' back through? It really all depends on the context, but what I have done is I have a set of exceptions that I use exclusively within the domain layer of the application. These are thrown or caught as appropriate, for instance, a SQLException is caught by my JDBC-using code, but when I rethrow this from my JDBC data access object business delegate I wrap it inside of a home-brewed PersistenceException. This way, if I switch to use a EJB data access object business delegate, I can catch the RemoteExceptions (or whatever EJB-specific exceptions are thrown) and wrap -them- into a PersistenceException. The advantage of this is that the facade-side of my data access objects don't have to know whether it's a SQLException or a RemoteException that caused the problem, it just catches PersistenceException and does what it needs to do. Sometimes I can end the exception-handling right here by performing whatever steps are needed to fix the problems. Other times, the facade (which is the outermost level of my domain logic right now) needs to report back to my Struts Action that there has been an exception. I don't have my code return a special return value if there has been a problem, rather I rethrow the PersistenceException wrapped inside of a DomainException. My Struts code can then handle only DomainExceptions without needing to know the details. But if I did need to know the details of the DomainException (such as to provide a more useful error message to the user as to what went wrong, or to email myself some info), I can unwrap the DomainException and get at the PersistenceException, or something. This is a simplification and not actually exactly how I've implemented it, but it shows two things -- 1, you can avoid messy situations with a long string of conditionals (or switch statements, which I don't care for) that test for return values by throwing a meaningful exception and putting the appropriate exception-handling code in the catch statement. 2, you don't need to expose all of your exceptions to every layer of your application -- some of your custom exceptions are exclusively used in your domain/model layer, others can be seen by the controller and can affect how it renders the view. Doing this helps keep your controller and model from being tightly coupled.

RE: [OT - Slightly] Returning Error Status from Business Layer
Erik - How then do you return a simple status from your business model to your action? There is not an 'exceptional condition' - simply a return value that the action can use to select the appropriate forward (for instance). As I've been looking into using exceptions to handle this, it appears that I've swapped a series of if-then-else constructs for a series of try-catch-catch blocks. So let me re-phrase my question - when a business model needs to return a status (not an exceptional condition (i.e. SQLException)), what is the 'best practice' for doing this?

While exceptions are awesome, I don't want to give the impression that they should be used for everything -- while in other languages such as Python, it is traditional to use exceptions for basic execution control flow (i.e., an infinite loop that is only broken by a thrown exception), in Java the idiomatic use of exceptions is that they are only used in "exceptional circumstances", generally when there is a problem of some sort. Also, AFAIK throwing an exception uses more resources than simply making a conditional decision. There is a great chapter in Joshua Bloch's book "Effective Java" on best-practices for using exceptions. If you find that a lot of your code looks like a long string of "if... else" statements or switch statements then you may wish to research Martin Fowler's "Replace Conditional with Polymorphism" refactoring.

mapping.getInputForward returning null
For some reason when I am calling mapping.getInputForward() I'm getting a
null value.
My BaseActionMapping extends ActionMapping so I can include a couple of
extra statements (see above). Everything seems to work OK -
my action is being called, the form bean is being instantiated, etc. The
first thing I do in my action is to set my default forward -
public ActionForward executeAction(BaseActionMapping mapping,
ActionForm form, HttpServletRequest request, HttpServletResponse response,
ActionErrors errors)
{
System.out.println(">>> mapping.getInputForward is " +
mapping.getInputForward());
ActionForward forward = (ActionForward)
mapping.getInputForward();
The value I'm getting in forward is NULL. Is there something I missed when
I extended ActionMapping?

Jerry,
Your methods are thread-safe. The MessageDigest.getInstance() and
SecureRandom() calls are thread-safe too. One thing I read while reading the
JavaDocs for SecureRandom() was:
This constructor is provided for backwards compatibility. The caller is
encouraged to use one of the alternative getInstance methods to obtain a
SecureRandom object.
You might consider changing your code to comply with this.

password)'. I don't think I have thread issues since I'm not using instance
variables, but I'm concerned about the use of the
MessageDigest.getInstance() and SecureRandom calls

RE: [OT] Use of Static Methods
To everyone: WOW! Talk about opening a can of worms! It's been quite
interesting reading the different viewpoints regarding the use of statics vs
singletons, whether Perl is OO or not, etc. etc. etc. It's this kind of
discussion that makes this list one (if not THE) best list on the web.
Ted: Thanks for answering the specific question. As much as I've enjoyed
the thread, all I really wanted to know is if my approach for these 'helper'
methods was appropriate or not. I'm not sure what you mean by 'whether
instantiating Password is an issue' - I can't think of a case where
instantiating any class would be an issue, so I guess I could change the
Password class to be a 'normal' class. The 'getEncryptedPassword()' method
is used by several different classes, so I don't really want to make it part
of a specific class - that's one of the reasons I moved it to a 'helper'
class and made it static. I guess the only question I have remaining is
whether there is a problem with maintaining 'thread safety' with the use of
a static method Is there a chance that two or more users can get to
the method at the same time and clobber each other?

It's mainly a question of whether instantiating Password is an issue. If
not, then make it a normal method.
Ideally, getEncryptedPassword should be a method of whatever class needs
to call it.
The benefit of static methods is that they can be called without
instantiating the class that contains them. So long as instantiation is
not an issue, then make it a normal method on whichever class needs to
use it. (Or make Password a member class of whichever classes need to
call it, and instantiate it when the parent class is instantiated.)

RE: [OT] Use of Static Methods
Thanks to everyone for weighing in on this. I certainly didn't expect this
type of discussion.
Let me give an example of what we are trying to do, and see if this is
appropriate or not. For various reasons we have a 'roll your own' logon
authentication process. Part of the process takes the users password, and
using a stored digest key, we encrypt it and then compare it to the stored
(encrypted) password. If they match, great. If not, then we return an
error. The code that we use to do the encryption looks like the following:
public static byte[] getEncryptedPassword(byte[] digestKey, String
password)
{
try
{
MessageDigest md =
MessageDigest.getInstance("SHA1");
md.update(digestKey);
md.update(password.getBytes());
return (md.digest());
}
catch(Exception e)
{
return (null);
}
}
The class name is 'Password', so to call this method we use something like
'Password.getEncryptedPassword(storedDigestKey, enteredPassword)'. Is this
type of method appropriate for a 'static' method? Or should this be a
singleton? Or a normal class?

Static methods are evil for many reasons including philosophical (they're
not OO) and practical (you can't override their behavior). You should use a
Singleton class with non-static methods.
Struts' RequestUtils class is a good example of why you should never use
static methods. Developers want to override their behavior but can't
because everything is static.

RE: ActionForm 'reset' method being called when JSP is rendered
Actually I am starting to think this is appropriate behaviour. After I sent
the original e-mail I realized that the ActionForm was NOT being
instantiated by Action1; in struts-config Action1 simply pre-populated some
beans and then forwarded to JSP2. It was when JSP2 was being rendered that
I was seeing the 'reset' method for the ActionForm being called. Diving
into the FormTag code, I found the following:
public int doStartTag() throws JspException {
// Look up the form bean name, scope, and type if necessary
this.lookup();
// Create an appropriate "form" element based on our parameters
StringBuffer results = new StringBuffer();
results.append(this.renderFormStartElement());
results.append(this.renderToken());
ResponseUtils.write(pageContext, results.toString());
// Store this tag itself as a page attribute
pageContext.setAttribute(Constants.FORM_KEY, this,
PageContext.REQUEST_SCOPE);
this.initFormBean();
return (EVAL_BODY_INCLUDE);
}
/**
* Locate or create the bean associated with our form.
* @throws JspException
* @since Struts 1.1
*/
protected void initFormBean() throws JspException {
int scope = PageContext.SESSION_SCOPE;
if ("request".equalsIgnoreCase(beanScope)) {
scope = PageContext.REQUEST_SCOPE;
}
Object bean = pageContext.getAttribute(beanName, scope);
if (bean == null) {
if (type != null) {
// Backwards compatibility - use explicitly specified values
try {
bean = RequestUtils.applicationInstance(beanType);
if (bean != null) {
((ActionForm) bean).setServlet(servlet);
}
} catch (Exception e) {
throw new JspException(
messages.getMessage("formTag.create", type,
e.toString()));
}
} else {
// New and improved - use the values from the action mapping
bean =
RequestUtils.createActionForm(
(HttpServletRequest) pageContext.getRequest(),
mapping,
moduleConfig,
servlet);
}
if (bean instanceof ActionForm) {
((ActionForm) bean).reset(mapping, (HttpServletRequest)
pageContext.getRequest());
}
if (bean == null) {
throw new JspException(messages.getMessage("formTag.create",
beanType));
}
pageContext.setAttribute(beanName, bean, scope);
}
pageContext.setAttribute(Constants.BEAN_KEY, bean,
PageContext.REQUEST_SCOPE);
}
The doStartTag has a call to initFormBean; in initFormBean there is a call
to RequestUtils.createActionForm, followed by a call to the ActionForms
'reset' method. In a wizard type of application, this could indeed cause
problems where the reset method may be clearing values from the ActionForm;
I've had to add code to a couple of my projects to check the mapping to see
if I wanted to reset or not. Maybe one of the guru's could shed some light
on why the tag would instantiate the ActionForm and call reset
when the JSP is rendered, opposed to doing this when the form is actually
submitted

RE: ActionForm 'reset' method being called when JSP is rendered
Ted, After I sent the original e-mail I found out that one of my developers had changed where the ActionForm was initially instantiated. The first JSP is calling an Action (via a that does NOT have an ActionForm associated with it. This Action preloads a series of JavaBeans and then forwards to the second JSP. The Action associated with this JSP does have the ActionForm associated with it, and since the ActionForm has never been instantiated, the tag was doing it at that time. I guess I never realized that the tag would do this (instantiate an ActionForm and call reset) - I've always been under the impression that the ActionForm, reset, and validate methods were not called until AFTER the form was submitted. Learning something new everyday . 8-) Thanks.

I'm seeing some odd behaviour with one of my actions. If anyone can explain this I'd sure appreciate it Here's what I've got - in struts-config I have an ActionForm that is shared by two Actions. The ActionForm is created in session scope by the first action, and referenced by the second Action (also in session). Tracing the calls to 'reset' and 'validate' I see the following: JSP is displayed -> html form is submitted -> 'reset' is called -> 'validate' is called -> Action 1 is performed -> forward to next JSP -> 'reset' is called -> JSP is displayed /\/\/\/\/\/\/\ ! My understanding is that 'reset' should not be called again until the form on the second JSP is submitted. Have I completely mis-understood how this works? Or is it something due to the ActionForm being created in session scope? TIA!

RE: Cloning Form Beans
Erik,
Thanks for the lesson - and I'll get out and get a copy of Josh's book. In
the meantime I've also discovered that 'clone' basically does a shallow copy
- i.e. if there is a nested construct of javabeans, clone will only copy the
hightest level, and then place reference pointers to the nested beans. I
think this is what is getting me. Does anyone have a 'deep copy' class that
will clone a complex javabean construct?

Whoops class, sorry, I forgot to finish the lesson. Bloch teaches us
that we should also make an internal copy of each argument to the
constructor:
public Period(Date start, Date end) {
this.start = new Date(start);
this.end = new Date(end);
}
This way if someone does still have a reference to the argument, they
can't modify that as a way into our immutable Period class.
Okay class is dimissed.

RE: Cloning Form Beans
So, something like this?
private String myString;
public String getMyString()
{
String returnedString = this.myString;
return (returnedString);
}
I'm not sure how this applies to my cloning issue....

Defensive copies... described in Josh Bloch's "Effective Java". Getter
methods return a copy of the property that they would return in a normal
class, so that client code can't affect that property and have the
change trickle back into your object. Required for immutable classes
that compose other objects which are mutable.

Not sure what you mean by 'defensive copies' Is there something special I need to do in my bean so I end up with a 'true' duplicate, and not just a second reference?

So if the getter on your bean isn't making defensive copies (and neither is the setter) then i'd imagine your newly cloned bean will have properties that reference the same object as the original bean.

Cloning Form Beans
Hi All, I have a form-bean defined in struts-config that is created in session scope in a setup action, then used in another three actions (kinda of a wizard thing). In the second action I have to make an exact copy of the form bean so I can do some comparisons between old and new values. I initially thought the the BeanUtils.cloneBean method would do the trick, but I'm discovering that when my struts form-bean is updated, the cloned bean is also being updated. Leads me to believe that a copy is not really being made, but a second reference is being created. This form-bean is a fairly complex set of nested beans; does anyone have a suggestion on the best way to handle this?
