RE: [OT] SQL Date to Util Date
A much simpler way of converting from a java.sql.Date to a java.util.Date is:
java.sql.Date sqlDate =
java.util.Date utilDate = sqlDate;
This will work, since java.util.Date is the parent class... However, I the original
question wasn't so much how to convert an SQL to a UTIL (I think the subject line is
incorrect), but rather how to simple display a date formatted on a JSP page.
As others have pointed out, this can be easily accomplished using the bean:format or
JSTL tags. (preferrably JSTL). There is no need to convert the sql.Date to a
util.Date, since - as previously stated - util.Date is the parent.
Hope this helps.

This is what I have now.

java.util.Date retDate = null;

java.sql.Date incomingDate = date;
String inDate = incomingDate.toString();

Both the SimpleDateFormat and DateFormat gives me back 2003-12-11.

RE: how to invoke the action servlet?
I think you'll want to go to http://localhost:8080/ginsu/ginsu.do The first ginsu is the name of your webapp, the second ginsu.do part will invoke the ActionServlet. This is because your web.xml indicates that anything with *.do should go to the ActionServlet. The ActionServlet will check the struts-config.xml file and see that since you are looking for ginsu.do, it should find the action named ginsu, which is your first defined action-mapping.

RE: how to invoke the action servlet?
You are correct about the file location... I'm assuming you meant struts-config.xml
and not slide-config.xml .. I'm not sure if it matters, but be sure the directory is
WEB-INF, not web-inf.
My suggestion to you would be to try and get the struts-example.war running ...
Just put the war file in your webapps directory (or unjar it there), then try to run
the example. If that works, you can slowly integrate your code into that webapp.
Surely you will find the point at which it starts failing.
Good luck!

Subject: Re: how to invoke the action servlet?
Ah, I am sorry. I forgot to mention that I had tried
different combinations of URLs. I did try
http://localhost:8080/ginsu/ginsu.do and I get the
same tomcat error as when I enter
http://localhost:8080/ginsu .
I also realize how vague I was. I'll try to be more
specific: I am using Tomcat 4.1.18, and I get a 404
with a description of The requested resource is not
available when I try these different URLs.
I went back to my %CATALINA_HOME%/webapp/ginsu
directory and discovered that my struts-config.xml
file was there. I think this is incorrect.
The web.xml file and the struts-config.xml file both
need to reside in my
%CATALINA_HOME%/webapps/ginsu/WEB-INF directory,
correct?
So I moved the slide-config.xml to the web-inf
directory and restarted tomcat and received the same
results.
Any further thought?
Thanks again, and I appreciate the fast responses.

Is this not possible in struts?
The URL of an action is composed like this:
http://${hostname}:${portnumber}${contextpath}${actionpath}
So, if you install your webapp at context path
/ginsu, and you want to
invoke the action with a path of /ginsu (which
appears to be the only
one you've defined), the URL would be:
http://localhost:8080/ginsu/ginsu.do
since you are using extension mapping. The first
part (/ginsu) selects
which web application, while the rest (/ginsu.do)
selects the action.

Struts officially supported at Ford
FYI … I thought people might be interested to know that Ford Motor Company has chosen Struts to use as their officially supported Servlet framework. Interestingly, support is being provided through IBM although I'm not sure what they can offer above the user list =) Here is the statement from the Java Center of Excellent website: quote The Ford Servlet Framework is a packaged version of Struts 1.1 provided by and supported by IBM. This download includes Struts provided by IBM with some custom integration of the other Frameworks and services provided by the Java COE. The Java COE will only be supporting the versions of Struts downloaded from here. Application teams should NOT be downloading Struts from the Jakarta website but are encouraged to use the website for learning and documentation. /quote I'd be interested to hear what people think about the last part of the quote… Currently, Ford is distributing 1.1b2.

You're right, the quote does not say anything about 1.1b2, but I can assure you, that is what is being used. It's probably written that way on the site so they don't have to change it so often =) . They do plan to go to newer releases, but there is going to be a delay between the actual Struts release, the time it takes for IBM to OK it, and then the time it takes for Ford to OK IBM's OK.

RE: Struts officially supported at Ford
Actually, the case is more impressive than you describe. Struts won out over several custom frameworks that currently exist within ford and have quite a bit of political clout behind them. What won out in the end was that there was no good cost-effective support model for the internal frameworks. Too many resources would have to be spent supporting/updating the alternatives. --- - Nayan Hajratwala - Chikli Consulting LLC - http://www.chikli.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 23, 2003 2:59 PM To: Struts Users Mailing List Cc: Struts Users Mailing List Subject: RE: Struts officially supported at Ford I agree here - The typical big company response would've been to build their own custom framework from the ground up. The fact that they chose to start with Struts shows they put a good deal of thought into it and trusted the quality of the work. It's very likely that they had internal projects be successful using Struts and then ramped it up as a standard. I'm sure they did a great deal of testing on it and had some camps pulling to build something custom. There were likely other competing frameworks as well. This is one of the greatest strengths of Open Source - as a large company you can take the app and customize to your internal environment. For example: - You could create abstract 'model' components that standardize they way people throughout the company perform database access (or web sevice access). - You could customize it to provide a standard method of acquiring and storing user credentials so that all applications manage user information the same way. - You could implement plug-ins to perform custom and standardized logging (assuming there is a standard logging process already in place). The possibilities are endless - I'll bet anything this is not the last time we here of a Fortune 500 company adopting Struts for intrnal development. Craig R.

It's absolutely appropriate for organizations responsible for mission critical software to be conservative in their version choices -- and every such organization I'm familiar with puts any potential new version through very extensive testing (for example, against existing apps or against any in house customizations they did to the previous version) before putting their stamp of approval on it.

I'm writing a CRUD-type app to manage news articles which will support users in various time zones. Individual articles have date/time stamps which are normalized to the server reference timezone as they are stored in the model layer. However, each user should see and modify the dates in his/her own timezone on the presentation layer, optionally specifying alternate timezones if desired. My current approach is the following (bear with me): - business layer object ArticleBO contains a Date field populated from db with ResultSet.getDate() - view layer ActionForm ArticleForm contains a Date object (internalDate) as well as String fields for date and time; internalDate is prepopulated from ArticleBO for view/edit actions - Article JSP contains two text fields for date and time strings, which are not themselves prepopulated from the ArticleForm, but rather filled in as the page loads via JavaScripts which use internalDate.getTime() to create a localized JavaScript Date object and corresponding date/time strings for the form - ArticleForm also contains a hidden field clientTimezoneOffset that is populated by JavaScript as (new Date()).getTimezoneOffset(), which is the client's GMT offset in minutes - ArticleForm returns to my add/edit/whatever Action after validation, at which point the date/time strings are converted back to a Date object using a SimpleDateFormat. The SimpleDateFormat is set to the client's timezone using the offset information in the clientTimezoneOffset field. This is tricky because 1. JavaScript-supplied values are the negative of what Java expects -- for example, California comes out as +8 (+7 DST) instead of -0800 (-0700 DST) 2. Since the offset value is adjusted for DST according to the local time on the client, the retrieval method must un-adjust it accordingly when setting the raw offset of the resulting TimeZone (which is DST-neutral) - ArticleBO populated from ArticleForm now holds a Date object in the server's timezone It took me awhile to figure that all out, and it seems to work well based on the testing I've done by setting the test lab machines' clocks/timezones every which way. It's an awfully convoluted process, though, and I don't like to rely on JavaScript. Has anyone else come up with a better solution?

RE: Need Help Fast
Essentially, he is saying you can rewrite your doStartTag method to be something like:
private List _states = null;
public int doStartTag() throws JspException {
if (_states == null) {
_states = new java.util.ArrayList();
_states.add(new com.ubspw.cdd.common.LabelValueBean(-Select One-, ));
_states.add(new com.ubspw.cdd.common.LabelValueBean(AK,AK));
_states.add(new com.ubspw.cdd.common.LabelValueBean(AL,AL));
_states.add(new com.ubspw.cdd.common.LabelValueBean(AR,AR));
...
...
}
pageContext.setAttribute(selectStates, _states);
return (EVAL_BODY_INCLUDE);
}
this way, states will only be set up the first time doStartTag is called.

Hello,
One possible solution:
Put the ArrayList in application context and put a check in doStartTag()'s
beginning to determine whether the list of states can be found in
application context.
Instead of:
pageContext.setAttribute(selectStates, states);
Put it like this:
pageContext.setAttribute(selectStates, states,
PageContext.APPLICATION_SCOPE);
And in the beginning of doStartTag():
Object o = pageContext.getAttribute(selectStates,
PageContext.APPLICATION_SCOPE);
if (o == null) { ...do what your current code does...
}
else { ...do nothing... }
But why do this in a tag at all? If your list of states never changes, you
might as well initialize it in an init() method somewhere.

RE: content management ideas?
Unfortunately, I don't believe this is a very practical approach. A content editor may inadvertantly make a change to a tag without even noticing it (search replace, fat-finger, etc). Then after they upload their change to the server and spend a few hours trying to figure out why it is displaying an error, they call you, the developer to debug the problem. You then compare the previous version (you are using source control, right?) with the modified version to see what the problem is... yada-yada. We use an approach of having a template which contains all of our base html .. header, footer, etc. The content editors can create whatever they want (we encourage valid XHTML, but usually don't get anything for our efforts), and upload it to the test servers. Our framework then pulls the content into the template via a custom tag (using java.io.*). Hope this helps...

But the site is very dynamic, with almost all page fetches resulting in a database query and dynamic content being built.

Yup, we looked at overall size of the JSP as well, and the association with performance was definitely number of bm/bw tags within a single JSP rather than overall JSP size. We even tried editing the generated servlet code and adding big unused methods to see if the problem had to do with generated servlet file size. That would kind've made sense, but was a negative. I believe we also tried a tag that just did a sysout rather than any kind of memory lookup (hashtable or properties file) and found that this performance quirk in the sun vm did not appear in that case. When you wrote your own tags (the message/write equivalents, I mean), did you happen to play with body versus non-body tags? When I was wrestling with the too many tags problem a while ago, I ended up writing my own versions of some of the Struts tags so that they were non-body tags, because they caused noticeably less code to be generated. I didn't measure performance differences, but I wouldn't be surprised to see a noticeable improvement there too. -- Martin Cooper We could never pin down a why, it seemed that the sun 1.3 vm just ran like a snail with a lot of bm or bw tags in a single page, so we stopped doing that ;-). Same number of tags split up into multiple JSPs, or a few tags called the same number of times via a loop - OK performance. It is very true also that splitting them up into smaller bites makes them more readable and maintainable, so it was a good solution all around. It's just that you are always nervous when you fix a problem and don't know the why of it ;-).

RE: ConcurrentModificationException when using nested:iterate tag
A ConcurrentModificationException occurs when you have an Iterator, and then modify
the underlying collection, then try to use the iterator again...
example (with bounds checking removed):
List list = new ArrayList();
// populate list...
Iterator i = list.iterator();
Object o = i.next();
list.remove(o);
// CME thrown here...
Object o2 = i.next();
The usual way to resolve these problems is to add and remove through the Iterator or
ListIterator rather than directly to the underlying collection. To fix the above, you
would replace list.remove(o) with i.remove(o)
So, in your example, on the line:
miaForm.addParm(new fw_MenuItemParmVO(null, null, false));
you are modifying the FastArrayList in the middle of the iteration.
Hope this helps!

RE: Hesitation leads to NullPointerException
are you sure that you haven't set the session timeout to 30 *seconds*?
Be careful to notice what the units being used by the timeout parameter
are... (minutes, seconds, milliseconds, etc)

Subject: Hesitation leads to NullPointerException
Using Struts 1.0.2 on Tomcat 4.0.2
bizarre.alert
I have a problem that only occurs if the user lingers on a page for a while
(say a few minutes). If after this duration, the user triggers any action,
the application crashes with a NullPointerException.
I have debugged the exception as being caused by a null property of the form
bean. The question is this: how did the list get to be null. Why does it
become null only if the user lingers?
The form bean (ProductsListBean) contains :
private ArrayList products;
public List getProducts() { return products; }
This list is used to display a collection of products for the user to select
(so, I know that the list is non-null non-empty). In the processing of
the user action, the following logic can be found
...
List products = productsListBean.getProducts();
Iterator iterator = products.iterator();
...
Obviously, (since the list is null) the application throws the exception at
the second line above.
/bizarre.alert
Since the stack trace on the browser didn't indicate the Root Cause I went
looking for the Tomcat log -- it said the same thing that was on the
browser. No more information.
BTW my session timeout is set to 30 minutes and the this problem presents
itself if the user pauses for 2-3 minutes.
