Re: Communication (in-vm) between webapps
My first thought would be ehcache all the stuff in front end with a reasonable expiration period (hours maybe), and then expose a very simple JMX interface to manually reset the cache without bouncing the entire app. No need to send much data over JMX other than just a simple 'refresh all caches' command. Pretty simple, but gives you a lot of options.

We recently implemented a StringResourceLoader which fetches translations from a database. So far so good. Now we face the following problem: the frontend uses this StringResourceLoader, but the actual translations are managed through the admin. Currently both apps are deployed on the same vm (and in the same tomcat instance), but this might change in the future. We need a mechanism to tell the frontend to flush the localizer (and StringResourceLoader) cache when the user clicks a button in the admin. After some investigation we've found a number of solutions, ranging from easy to complex: - cross context = true, share a boolean through the ServletContext and poll for it to change - have the frontend expose an MBean (JMX) which the admin can control - use a message bus for communication (e.g. rabbitmq) - cluster communication, such as jgroups or hazelcast Can anyone comment on this? I'd prefer to keep things simple at this stage (e.g. setting up an external message bus for this seems overkill), but having something which works as we scale out would be preferable. Sebastian
Re: wicket + jasper reports
Got it - found another hint about DownloadLink that led me to this solution:
@Override
public void onSubmit() {
ReportResource resource = new PdfReportResource(getReportName(),
getParamsModel());
getRequestCycle().scheduleRequestHandlerAfterCurrent(
new ResourceRequestHandler(resource, null));
}
So simple, but it took some digging to find so hope this helps someone else.

Re: CouldNotLockPageException using localized RequestMapper URLs
Thanks - I did that, and found the culprit was a file upload (that part was
okay) which fed into an piece of image resizing code:
Graphics2D graphics2D = rescaledImage.createGraphics();
which the stack trace showed was waiting forever on some other AWT init
thread.
So I just kicked it to the curb and used another image scaling library from
http://code.google.com/p/java-image-scaling/ and the problem has gone
away! So not wicket related at all.
In retrospect, I can't think of a more informative way the framework could
have helped me discover this - my breakthru came from the old
tried-and-true method of finding a way to reproduce the issue (of course
that is the hard part - seems like it took forever, trying to explore all
the functions in my system) and then when it finally happened, doing a
thread dump.
Anyway, situation resolved! Back to happy wicket coding...

Re: ResourceReference.getResource() returns NULL ?
Search for Dynamically loading image for good examples of how to do this.
Basically, you do not put the image data directly into HTML. Instead, you
make your page.html with some table perhaps, and a series of links to your
images. So you would need one method to list the ids of your images to put
as a parameters into your links. Then, you will 'mount' the resource in
your application class at app init time, which will allow your app to serve
up the image data for each img src=mountpoint?id=123 tag.
Good luck

Internal Error shows up in Google Cache
I mentioned a few weeks ago I had some page locking issues.
I turned on logging and overrode the PageAccessSynchronizer to log and
swallow the page lock exception (it still has the timeout wait, so
it's not totally disabled), but of course it hasn't happened since, so
I still haven't found the root cause other than some heavier usage
(1500 page loads/day is busy for me - go ahead, laugh ;)
... but now I just noticed my search results in Google are showing
these Internal Error page in search results!
Yikes - Bad news!
So, my band-aid fix is this:
protected final class MyInternalErrorPage extends InternalErrorPage {
private static final long serialVersionUID = 1L;
@Override
public void renderHead(IHeaderResponse response) {
response.renderString(META NAME=\ROBOTS\ CONTENT=\NONE\ /);
}
}
and in my application init():
getApplicationSettings().setInternalErrorPage(MyInternalErrorPage.class);
I'm thinking this might be a good default for this page?
Of course we don't want internal errors in the first place, but if
they do happen (to a robot), no reason to literally advertise the
fact, right? Seems like a drag on the brand name to some degree..
On a side note, does anyone know how to tell google to get rid of a
cached search result like this, or am I stuck waiting for the next
robot to come along?
To see what I mean, google for Together Auction (2nd result, crawled
May 21, still here June 3):
Catalog - Internal Error
Internal error. Return to home page.
togetherauction.com/firstuu/catalog - Cached
OK, back to the page locking issues - the only unusual thing I'm doing
is that I have my app deployed at my domain root with suffixes for
each of my clients so they each appear to have their own version of
the web app served from a common ROOT.war. So my URLs are like this:
mydonamin.com/clientname/restOfURL. This is done via a
ClientFirstRootRequestMapper extends AbstractComponentMapper
(source if anyone is interested: http://pastebin.com/Zxp561JK )
For some reason, this was working great in 1.5 M3 but since I've
upgraded to RC3, I'm seeing ;jsessionid= on all my URLs now - not sure
if that is related.
I mention the RequestMapper because I wonder if this might result in
two different clients using same page class with instance keys that
might not be unique and thus have locking conflict from that ?
Thanks for any insights any of you wiser wicket ones might have to share.

Re: Copying PageMaps from one session to another
To expand on Josh's suggestion, In your Login link (probably on an abstract page you inherit for other app pages) you would have an onClick that doesn't just setResponsePage(YourLoginPage.class), but instead throws the Restart...exception. That way, when the login completes, it should come back to the page the login link was pressed on. -- Jim.

Help I need to understand page locking
I'm using wicket 1.5 RC3 and just started getting some total system lockups recently in prod that I can't understand. Once it gets into this state, the only remedy is to restart tomcat. Unfortunately, I haven't yet figured out how to reproduce this, so meanwhile I thought I'd ask if someone could please help me understand how page locking works in general and what I should be looking for.

I could try refactoring that, but without a reproducable test case, it's just a guess at this point. My other plan would be to revert to some older wicket version, but again, just a guess.

Re: Help I need to understand page locking
Thanks, good tip. I'll do that, and I'm also going to send in a replacement copy for PageAccessSynchronizer that still has the one minute delay, but then if it fails, it forces the lock anyway and swallows the exception - hopefully that will solve my lock ups until I can find the cause: locks.put(pageId, lock); // force it - temporary fix only logger.error(failed to acquire lock would have thrown: , /*throw*/ new CouldNotLockPageException(pageId, thread.getName(), timeout)); Thanks, -- Jim.

Re: Last Page visited
Well, most browsers already have back button, so I'm not sure why you would
want to re-implement that, but assuming you do, here's one way to do what I
think Martin is suggesting by pass a page reference:
abstract class AbstractBase extends WebPage {
PageReference priorPage;
public AbstractBase(PageReference priorPage) {
this.priorPage = priorPage;
}
public PageReference getPriorPage() { return priorPage; }
}
class PageThatNeedsABackButton extends AbstractBase {
public AnyOtherPage() {
super(getPage());// you need to tell it where 'back' is as
you make each page
add(new Link(id) {
public void onClick() {
setResponsePage(getPriorPage());// then later you can
go there
}
});
}
Hope that makes sense. Not a great idea, but hope it helps to experiment
and learn.

It not works.
I did: setResponsePage(getPage().getPageReference().getPage());
My structure is:
Page (a separated class)

|- Button (a separated class BackButton)
Each component is a separated class in our application.
The Button code is:
public class BackButton extends Button {
public BackButton(String id) {
super(id);
setDefaultFormProcessing(false); // because it is inside a
form and cannot make submit forward
}
@Override
public void onSubmit() {
setResponsePage(getPage().getPageReference().getPage());
}
}
On debug, the inspect of the first getPage() is the same Page as
getPage().getPageReference().getPage().
In the class BackButton I do not have direct access at
getPageReference().
I Just need know the preview Page, and don't care witch Page is, because
the business rules can create different
paths to the user.

The

do not gave me preview Page. It gave me the same Page.
Is there a way to get the Page.class reference of the preview Page?
The code I've tested getPageReference() is:

[Vote] New Wicket Version Numbering
I've had a hard time lately trying to get corporate acceptance of the Wicket framework. In fact, our company looked at this comparison of java frameworks: http://en.wikipedia.org/wiki/Comparison_of_web_application_frameworks *Project* *Current Stable Version* Apache Click 2.2.0 Apache Cocoon 2.2.0 Apache Struts 2.2.1.1 Apache Tapestry 5.2.4 Apache Wicket 1.4.15 AppFuse 2.0.2 Aranea 1.0.10 Eclipse RAP 1.2.0 FormEngine 1.7.1 Google Web Toolkit 2.2.0 Hamlets 1.6 IceFaces 2 ItsNat 1 JavaServer Faces 2 JBoss Seam 2.2.0 GA Jspx-bay 1.1.0 JVx WebUI 0.8 ManyDesigns Portofino 3.1.10 OpenLaszlo 4.1 OpenXava 4.0.1 Oracle ADF 11.1.1.4 Play 1.1.1 RIFE 1.6.2 Shale 1.0.4 Sling 5 SmartClient 8 Spring 3.0.5 Stripes 1.5.4 Telosys 1.1.1 ThinWire 1.2 Vaadin(IT Mill Toolkit) 6.5.1 Wavemaker 6.1.10 WebObjects 5.4.3 WebWork 2.2.6 ZK 5.0.5 ztemplates 0.9.9.6 The powers that be decided to pick Smart Client over Apache Wicket because they have the highest version number.

Suppose the user is on the Home page, and the Home Page

Then the link itself sets an intercept to the sign-in page
(that is how the link arranges to take you there, as far as I can

But then, when the user enters name/password and submits, and
the submit method calls continueToOriginalDestination(), it will
always succceed, and find the original destination to be the
signIn
page, regardless of where it really originated (the Home Page, in
this case).
You're a bit confused by original and destination. Since the
user
clicked the signin page link, the *destination* was the signin
page
-
which is unrestricted, so the continueToOriginalDestination()
method
can
not
redirect them anywhere, and thus returns false. You now need to
redirect
them somewhere manually
Re: [1.5] Two formcomponents editing the same model?
Hmm... If I were designing a component like this (and for some reason didn't
like the ones out there like datepicker that already do this) I'd make a
new component that extends panel with 2 separate child controls, each with
their own date models. Then use a top level model getter / setter that
just pushes/pulls the 2 child dates independently using the
java.util.Calendar's fields independently.

continueToOriginalDestination() lets the user continue on to the place they
were going before being interrupted by the security mechanism if they
aren't
logged in. i.e:
user on home page
user clicks restricted page link
security strategy says can't go there without being logged in as X,
redirects user to login page
user logs in, and continueToOriginalDestination() redirects to restricted
page (original dest) and returns true.
another example:
user clicks bookmarked link in a new tab in their browser to login page (or
goes to unrestricted home page and clicks link for login page)
user logs in, and continueToOriginalDestination() can't redirect them
anywhere, because there is no original destination that was interrupted
Page 272 Listing 11.4 , new Link(...){ ... method onClick():
throws new RestartResponseAtInterceptPageException(signInPage)
This is a way to stop processing at ANY point in your application and
redirect the user to a certain page.
How is this supposed to work?
Suppose the user is on the Home page, and the Home Page
has a UserPanel, and the user clicks on the Sign In link.
Then the link itself sets an intercept to the sign-in page
(that is how the link arranges to take you there, as far as I can
understand).
But then, when the user enters name/password and submits, and
the submit method calls continueToOriginalDestination(), it will
always succceed, and find the original destination to be the signIn
page, regardless of where it really originated (the Home Page, in
this case).
You're a bit confused by original and destination. Since the user
clicked the signin page link, the *destination* was the signin page -
which is unrestricted, so the continueToOriginalDestination() method can
not
redirect them anywhere, and thus returns false. You now need to redirect
them somewhere manually or the signin page will re-render.
The *origin* was the home page - but that doesn't matter. Don't be thrown
off by original (destination) and origin - which are two different
things. :)
For a while my code was working like that: Signing in worked,
i.e. it did sign you in, but you were returned to a blank sign-in page.
(My code doesn't work like that just this minute, but that is only
because I've been enhancing it with other bugs.)
Can anyone explain how the book-example is supposed to work?
Thanks
Jim

Re: [VOTE] WICKET-3218 - Component#onInitialize is broken for Pages
Interesting problem.
It helped me visualize the issue when I tried to suggest:
myPage() {
add(new Thing(this,...)); // 'this' doesn't exist yet
}
I think building component hierarchy from constructors feels natural and
it's going to be a hard sell to change to support this use case where some
components might need to know their parents.
I thought I was keeping pretty much up-to-speed on 1.5 changes, but I'm kind
of surprised this is the first I'm noticing this fairly substantial API
change.
Sorry if something like this has already been shot down - I didn't look -
but just off the top of my head, seems like there could be a way to have the
framework (as it is about to add a page to it's map or at some other
convenient early point) go back down thru the hierarchy and visit all the
components to offer them a parent reference? Maybe guarantee it would
happen before the first onBeforeRender or something like that?
Then, we could let these visitors 'vote' on when the hierarchy is finished
changing - (i.e. components could use this information to make additional
changes to the hierarchy) by returning a value. Perhaps call this new
component visitor something like int onParentChanged(Component parent) -
return flags that would let the framework interrupt and restart, repeat
after finish, or just continue visiting (or maybe just return boolean repeat
flag).

How to make DateTimeField default to PM
I wanted to have my DateTimeField (That's the wicket-extensions component
with a date text field, button to open calendar, and hours/minutes fields
with optional AM_PM choice) default to PM instead of AM for new dates
because I noticed most dates in this part of my app are evening dates.
I came up with this; maybe it helps someone, or let me know if you have a
better way:
FormComponentDate dateField = new DateTimeField(eventOn) {
private static final long serialVersionUID = 1L;
// amOrPmChoice is final, so we have a little kludge to
default new item's eventOn date to PM
// TODO: find a less clever way
@Override
protected void onBeforeRender() {
Date d = (Date)getDefaultModelObject();
if (d == null) { // user hasn't entered a date (yet)
Calendar c = Calendar.getInstance();
c.set(Calendar.HOUR_OF_DAY, 18); // anything after
noon would work
IModelDate dm = (IModelDate) getDefaultModel();
dm.setObject(c.getTime());
super.onBeforeRender(); // initializes
amOrPmChoice as side-effect
dm.setObject(null);
}
super.onBeforeRender();
}
@Override
protected DateTextField newDateTextField(final String id,
final PropertyModelDate dateFieldModel) {
return DateTextField.forDatePattern(id, dateFieldModel,
MM/dd/);
}
};

Re: Free wicket from component hierarchy hell
I'm not a committer, just a normal 1.5 user concerned about bloat. For what it's worth, I took a few minutes to actually look at the change (MarkupContainer as you'd expect) and I can see that if you don't use the new queue methods, the only a memory overhead is the *static* QUEUE (nothing extra per component!) so I appreciate that performance-wise anyway, it's a low impact feature you can ignore without penalty. I'm not thrilled about the conceptual impact of adding a new concern to an already large class, but the implementation looks quite nice actually, so my first concern that it might break existing behavior is satisfied. I still don't think it's necessary, and wonder if it might actually be counter-productive to have more than one way to learn for new adopters. If it goes forward, I don't suppose there's much precedent for taking something back out, is there? What a difficult discussion to have over email - I'm in the -1 camp on this overall, but I think I do appreciate the admirable motive to innovate, so I hope the committers will give this serious consideration and then chuck it in the bin where it ... no, just kidding, ;) and then make a fair decision.

(Although even then, mvn eclipse:eclipse didn't add it - I had to add it
myself to the classpath! - perhaps because it's declared as optional in

So now I can click on my link and download an XLS, but then I get this
lovely message:
Excel found unreadable content in 'report1xls'. Do you want to recover the
contents... OK sure... then:
'Damage to the file was so extensive that repairs were not possible.
...etc'.
The resulting workbook that finally opens looks like it's ok at first, then
all messed up starting a few pages down where a string value contains an
ampersand (It's possible the data has some HTML like amp;).
To say that I'm out of my element here is an understatement.
If I don't get any better ideas, I'll go with this hack (notice I switch to
using the HTML exporter):
private static IJRResourceHandler fixXls(IJRResourceHandler handler) {
// kludge for xls
if (handler instanceof XlsResourceHandler) {
return new XlsResourceHandler() {
private static final long serialVersionUID = 1L;
@Override

exporterXLS.setParameter(JRXlsAbstractExporterParameter.IS_DETECT_CELL_TYPE,

exporterXLS.setParameter(JRXlsAbstractExporterParameter.IS_WHITE_PAGE_BACKGROUND,
Boolean.TRUE);
exporterXLS.setParameter(JRXlsAbstractExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS,
Boolean.TRUE);
return exporterXLS;
}
};
}
return handler;
}
But it makes all kinds of ugly dead image links every other row and column
around the data. Yuck.
Any other jasper users want to share any tips here?

RenderBodyOnly and email links
Many may already have realized this, but for anyone who hasn't, I just came
across this elegant way to handle optional emails.
The user/admin stuff is just an example use-case, simplified to fit here.
// User's Statement page lists some items and who bought them...
AbstractLink myLink;
if (isAdminUser()) {
// admins can view the buyer's full info
myLink = new BookmarkablePageLinkMemberPage(buyer.link,
MemberPage.class, params)
} else {
// normal users get email links to each other instead
myLink = new ExternalLink(buyer.link, email);
// or if they don't have email, just show their name
myLink.setRenderBodyOnly(email.isBlank());// if they don't have
an email
}
myLink.add(new Label(buyer.name));
Before I found this, I had two separate elements - the a link with it's span
name inside, and then another span name with only one or the other visible -
that was ugly.
Maybe this helps someone else

maybe this authorization strategy helps someone
I needed to authorize some pages not just by annotation but also based on
PageParameters.
I came up with this:
App.init()
((CompoundAuthorizationStrategy)getSecuritySettings().getAuthorizationStrategy())
.add(new RequiresRolesUnlessAdminAuthorizationStrategy(new
Roles(ADMIN)));
public interface IRequiresRole
{
Roles requiresRoles();
}
public class ProfilePage extends MyWebPage implements IRequiresRole
{
private String id;
public ProfilePage(PageParameters p) {
id = p.get(id).toString();
}
public Roles requiresRoles() {
return new Roles(id); // I'm just using the id as a role for
testing but you can lookup your object and see what roles it needs here
}
}
And the fun one:
public class RequiresRolesUnlessAdminAuthorizationStrategy implements
IAuthorizationStrategy {
private Roles alwaysAllow;
public RequiresRolesUnlessAdminAuthorizationStrategy(Roles alwaysAllow)
{
this.alwaysAllow = alwaysAllow;
}
public boolean isActionAuthorized(Component component, Action action) {
if (component instanceof IRequiresRole)
{
Roles r = ((IRequiresRole) component).requiresRoles();
return AuthenticatedWebSession.get().isSignedIn()
(
AuthenticatedWebSession.get().getRoles().hasAllRoles(r)
||
(alwaysAllow != null
AuthenticatedWebSession.get().getRoles().hasAnyRole(alwaysAllow))
);
}
return true;
}
public T extends IRequestableComponent boolean
isInstantiationAuthorized(
ClassT componentClass) {
return true;
}
}
So if you are ADMIN you can do anything, otherwise you need whatever role
corresponds to object identified by the PageParameter id.
Am I re-inventing someone's wheel here, or does this sound good?

how to have one app at multiple root contexts
I've got a wicket 1.3 app I'm refactoring to add security and more scalable 'root contexts'. I think may involve going to wicket 1.5 but I haven't found any actual examples of this to study - seems like it would be a common need. Right now, I have a dozen different maven profiles that crank out nearly identical war files named for each profile (aka root-context aka clients). I'll run out of memory soon with this approach so I'd really like to get back to just a single war file to deploy at root context and somehow pull the client names dynamically. It would be OK to redeploy to add client mappings at app.init since there is some db config for each new one anyway, although it would be best to have no outage for other clients when new one is added For the security, I found a great help herehttp://out-println.blogspot.com/2009/02/wicket-swarm-spring-security-how-to.html. Unfortunately, it doesn't work with Wicket 1.5. Anyone working on that? I gave it a quick effort, but got stuck on the WaspWebApplication's newRequestCycle method which I just don't understand. The best I could do was get it all working with: wicket.version1.4.13/wicket.version swarm.version1.4.1/swarm.version (and for this I had to declare and download manually: swarm,wasp,hive,wicomsec) jetty.version6.1.25/jetty.version spring-security.version2.0.4/spring-security.version I had thought to try spring-security's OpenID authentication so my users could use their existing gmail or flickr or whatever ids and not have to create a new one just for my sites... but now I'm thinking to keep it simpler and just use wicket-auth-roles in order to use wicket 1.5. Can anyone offer advice to help me make progress on either of these issues? Thanks, -- Jim. http://togetherauction.com

learn from my security mistake with getString
I was just looking around for my dunce cap after noticing this little gotcha
- and I thought of this forum instead to share my moment of
not-so-brilliance:
public LoginForm(final String id) {
... other stuff ...
add(new FormComponentFeedbackBorder(user.feedback).add(new
TextField(user).setRequired(true)));
passwordField = new PasswordTextField(password);
passwordField.setRequired(true);
add(new
FormComponentFeedbackBorder(password.feedback).add(passwordField));
}
protected void onSubmit() {
String password=getString(password).trim();
if (password.equalsIgnoreCase(getPassword())) {
((AuctionSession)getSession()).setAdmin(true);
((AuctionSession)getSession()).setUserName(getUser());
if (!continueToOriginalDestination())
setResponsePage(getApplication().getHomePage());
} else
passwordField.error(invalid user/password);
}
}
Pretty basic, I know. Maybe you have a page like this in your Wicket app?
The mistake I wanted to share is that I'm using the same name for the
password wicket:id, and the string property in MyLoginPage.properties,
which just has a line that says password=super_secret_whatever. (Actually,
it's ${profile.password} and I have different maven profiles for different
versions of the app, but that's another story).
Anyway, imagine my suprise when I accidentally left the password blank by
mistake - the required error message uses the same property and shows the
password to the wide world in the feedback message: 'super_secret_whatever'
is required. Hah!(Yup, it's been in production for quite a while like
this...)
Just wanted to share that one with y'all - may all your mistakes be
entertaining and/or educational...

Configuration Q re Maven Profiles and Start
There must be something simple I'm missing - I'm fairly new to maven, but I
love the profile feature for different client versions of a hosted turnkey
app I'm working on.
So, I build multiple war files specifying each -PprofileName and rename the
WARs to the context root I want (usually same as the profile name) and
deploy them - everything works OK. This lets me put references to
${profile.thisOrThat}
in various places - html files, Somepage.properties, even
applicationContext.xml and web.xml.
But I realized, I've now lost the handy ability to debug Start.java - of
course, it sees the plain version of these config setting, so it doesn't get
very far. This is slowing me down on minor HTML tweaks, for example, that
used to be super-fast and easy cause now I'm back to the old fix, compile,
deploy dev cycle.
I've got the Eclipse maven plug in, and I've made a Debug Configuration of
type Maven Build but I'm not sure what to put for the goal.
Something like run org.mypackage.Start ?
Thanks for any clues,

Re: Multiple Copies of One Wicket App
I have a follow-up question related to this. My current setup is simply myclient.war with my web.xml having one filter-name and one filter-mapping with url-pattern /* so my home page is myhost/myclient. Life is good, but now I'm growing! What I'd like to do is have separate versions of the app for several clients. So I'd rename myclient.war to generic.war, then have several filter-mappings with url-pattern /myclient and /mynewclient. I think this way I can have specific init-param entries for each one and get the right database and so forth for each one - that's pretty much how I read this answer, so that's great as far as it goes. So my followup question is, I have some ThisPage.properties files with text specific to my current client, and I'd like to have some way to load properties in a consistent way, perhaps ThisPage.properites, with overrides taken from myclient.properties - kind of like locales, but not exactly. For that matter, I might even do the same thing with ThisPage.html and ThisPage.mynewclient.html files. I also have a few MyApplication.properties. Perhaps I could refactor these (there aren't too many) into some other organization? Anyone have any tips for me in this regard? I don't anticipate any other future locales other than default US, but I'd hate to break from convention allowing for that if there's a better way. I'm still on 1.3.7 btw, if that matters.

Re: Handling Ajax session expired
I think this suggestion is worth condsidering more carefully: Can you just achieve what you wan't making siloA, siloB, siloC been different Wicket applications? No, that is not the proper solution. They are the same application. OK, but could you deploy multiple copies of the same app to different root contexts - that would give you the info you want in each URL and thus be able to do different home/error pages with some config along with each copy of the app. Seems worth exploring whether your Silos might divide well in this manner, maybe with a bit of work, but probably more likely to happen than what it seems like you are looking for, which doesn't sound (just one casual observer's option) broadly applicable enough to warrant framework inclusion.

Re: Highlight some words in the markup content
I'd be interested to know if anyone else is using this technique for search
highlighting with a DataTable.
http://pastebin.com/m5446797d
The data in my grid may contain HTML, so that makes it considerably more
complicated (my first attempt didn't address this problem). I'd love to
know if someone else has a better/simpler way, although this does appear to
work fine, it took a day to come up with.
In general, I kind of like the idea of separating this concern from the
model, whose purpose is just to get the data, and think of this search
highlighting as more of a decorator that applies to the entire grid rather
than any particular column, since I've got several PropertyColumn subclasses
(LinkPropertyColumn, ImagePropertyColumn, NonEscapedHTMLPropertyColumn,
...etc).
Hope this helps someone else.

img tags from external src slow down my page
Hi, I have an AjaxFallbackDefaultDataTable on the main page of my Wicket app with an image column like this: columns.add(new ImagePropertyColumn(new ResourceModel(imageURL), imageURL)); My item model has an imageURL string property backed by a database column, and it pretty much works OK. I don't need to store any images, bandwidth is low, and it's simple, but I have seen some users enter URLs to huge TIFF images that are not properly sized, and it makes my page display take forever. I'd like to try to fix or prevent this. I had a few ideas: 1. a note on the item entry page asking users to 'please don't do that'. :) 2. add an ImageURLValidator to check the image size somehow... hmmm... 3. find some utility to help read the image, properly size it, and store a local copy with my own id (filesystem should work fine) and let my model's imageURL property point to it. I'm trying to write this so it could scale up a bit without getting crazy - This app lists items for a charity fundraising auction event, so access is light for several weeks, then peaks at about 300 hits per day (I know, not much) for a few days. But on those peak days, I'd like it to be fast (despite the decrepit old server it's running on). I've got about 300 items to show on a single page (users prefer a simple scrollbar without pagination). Also, I should mention that I have a search form that 'decorates' the matching text as it filters rows, and I'd like to make it fast enough to take away the search button and just ajax refresh on keypresses.

Re: Google App Engine and Wicket
I've followed with interest all the wicket on GAE threads I can, and these all seem to address necessary minor tweaks to get it set up, but the one big thing I haven't seen much discussion on is the BigTable storage system, since we wouldn't be able to use MySQL. Maybe that's the whole point for some folks looking for high scalability, but from my perspective, I'm more interested in the idea of a free turnkey(ish) Java hosting environment. I'd like to be able to resell my wicket app (it's a fundraising auction system designed for nonprofits) to lots of tiny churches or other nonprofit organizations - they typically have no IT experience, so bypassing the hosting concerns could be a big win. Plus, the system would be ultra low traffic by google standards especially (maybe 8 concurrent users tops per org during peak demand!). Right now it's 'incubated' as an old underpowered Windows 2000 server running Jetty sitting in a closet at my church, where the business class ISP licence agreement legally permits it. Seems like quite a leap to be considering GAE, but if it's free and folks trust the availability and I can easily configure it for each additional client, that could work out pretty well for me. But of course my system is all heavily SQL oriented - seems like this would be a pretty fundamental rewrite for me to go to BigTable, and I was wondering if any other wicket developers were also attracted to this type of system, for these or other reasons, or whether I should just shell out for some shared hosting blades and go for it?

Kaspar Fischer almost posted the following: My app takes quite some time to start up, so I don't want changes to my Wicket HTML or Wicket Java files to cause Tomcat to completely reload the web app. Is it (at all) possible that only the changed Wicket HTML/Java/.properties file get reloaded and the rest (Spring beans, etc.) stays? Yes. It is working for HTML, Java, and .properties files under Eclipse with WTP and Tomcat. I am a little confused about the terms used in this context. Here's how I see; please correct me if I am wrong. - Hotswapping means replacing a given class implementation with another one. - Publishing (as seen in the server configuration panel in Eclipse when clicking on a Tomcat server in the Servers view) means shutting a webapp down and restarting it, hithout actually shutting Tomcat down. I can't answer myself on this. But I guess it's more or less fine ;-) There is also an option Update context paths in the Tomcat Server configuration panel (under Publishing). Is it related? It is checked in my set up but I don't know whether it is related. Finally, *how* can I get Tomcat/Eclipse/Wicket to only reload Wicket HTML/Java/.properties files that changed? In particular, I am unsure whether I have to: - Debug instead of Run the server (i.e., click Debug in the Eclipse Servers view)? With Debug it works. - Should the server have Automatically publish when resources change selected (in the server's configuration panel in Eclipse)? I have this checkbox checked. - What Tomcat Context configuration must I use? I currently have something like: Context docBase=myproject path=/myproject reloadable=true source=org.eclipse.jst.j2ee.server:myproject/ This works for me. - In the server's configuration panel, in tab Modules, should I check Auto reloading enabled? No. Otherwise Tomcat reloads the *whole* webapp. I know that Wicket must be running in development mode. I think so, too ;-) Many thanks for any pointers and sharing your settings!

Re: serialVersionUID
I'm suprised no one has mentioned the runtime cost of computing a default serialversionid which is avoided if a constant is supplied. I used to make it a habit for this reason. This thread made me curious if that was really true, so I googled a bit and found this articlehttp://www.javaworld.com/javaworld/javaqa/2003-06/02-qa-0627-mythser.htmlwhich found no such benefit, and suggests we needn't bother. I think I'll turn off the Eclipse warning instead. -- Jim.

It only prevents trivial changes (e.g. adding a public method) from breaking your serialization compatibility. You can still break the compatibility even with a serialVersionUID, e.g. by renaming a field. Besides, Wicket page maps are neither long-term storage nor remotely communicated, so I don't really see the point of putting in the effort. I'd say that its easier to just add it in case you ever need it, its only 1 line of code. Given Wicket's reliance on component inheritance, adding serialVersionUID in every place Eclipse complains about it would amount to hundreds of lines of code on my projects. Java code has enough noise already. jk - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Can client cache pages effectively?
A quick follow up in case anyone else was curious about how this is going: I ended up using ehcache page cache filter for a simple page that just displays 'current' items (calendar view of events) based on a db query. No forms (state) on this page so it works pretty well. In my DAO that does updates, I clear the cache. Very simple, works great. (Only catch I ran into is that my menus change when I have a session and I'm logged in as super-user, so I have to make sure I don't let that version of the page be cached - I do that by adding 'super' page parameter so URL is different and filter is set to only cache the 'normal' version. So, that still leaves me with my main catalog page, which is primarily a similar list of items, but it also has some active content (in particular, a search form). So my bright idea (tm) (i.e. I'd love to hear critiques before I get too far along with it) is the following: Make a new page for just the data grid, with page parameters including the search string and last-modified date (and super-user login because I get some edit links and such with that). Mount it and ehcache it, and override setHeader so it becomes client cache-able. Then, my outer catalog page with the search form on it just uses an IFrame to display the grid data (easy to keep track of last-modified globally). Same clear method in DAO dumps the cache whenever a change is made. Also, I'd want to make a robot no-follow thing to avoid google trap on that page. Could this actually be a legitimate use of otherwise dodgy IFRAME ? Sound like a good plan? Thanks, -- Jim.

Re: How To Download Excel File?
Another way I'm using is like this (it works best if your clients have excel
installed of course)
Markup: http://pastebin.com/m41ee5cbe
Java: http://pastebin.com/m488291d4
With the most important bits being:
@Override
protected void configureResponse() {
super.configureResponse();
getRequestCycle().getResponse().setContentType(application/x-msexcel);
}
and then a simple DataView with something like this:
...
head
titleExcel Download/title
meta http-equiv=Content-Type content=application/x-msexcel
meta http-equiv=Content-disposition: attachment;
filename=whatever_default_filename.xls
/head
body
table
tr
thName/th
... more ...
/tr
tr wicket:id=rows
td wicket:id=namenbsp;/td
That makes most browsers open a dialog box where the user can open (usually
in excel) or save the html - no binary conversion to excel's file format is
really needed - excel can read HTML just fine. So if you are just doing a
simple tabular report like I'm doing here, this could be a good option for
you.

I have a SQL database table with about 1,000,000 rows. The user can enter a search string, and my application returns a list of all the rows that match the search string. This list might be over 10,000 rows. At first I thought this would be a perfect situation for a DataView, since it involves large numbers of rows, and I don't necessarily want to get all 10,000 rows if the user only needs to look at the first 20. However, I'm finding that, since DataView re-queries the database with each page view of the results list, any time advantage I might have gotten initially is quickly lost. It seems that using a PageableListView, I just query the database once and I'm good. So my question is, am I misunderstanding the purpose of the DataView? All of the online examples I find for DataView use Java databases rather than SQL relational databases. Is the DataView only useful if you already have some kind of a Java database to back it up? Or is there some way that I can take advantage of DataView in this situation without having to re-query the database whenever the user clicks to a different page of the result list? _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ EMAIL CONFIDENTIALITY NOTICE This Email message, and any attachments, may contain confidential patient health information that is legally protected.

head

body
table
tr wicket:id=rows
td wicket:id=idnbsp;/td
td wicket:id=member.idnbsp;/td
td wicket:id=namenbsp;/td
That meta content in the head is more for documentation - it doesn't seem to
work without the final step below:
The Java code looks something like this to populate the table:
add(new DataView(rows, new MyDataProvider()) {
public void populateItem(final Item item) {
item.setModel(new CompoundPropertyModel(new
DetachableXYZModel(item.getModelObject(;
item.add(new Label(name));
And the final magic makes it ask if you want to open it with excel:
@Override
protected void configureResponse() {
super.configureResponse();
getRequestCycle().getResponse().setContentType(application/x-msexcel);
}
That worked for me - hope it helps. (Also note you can output a mix of
literal data and formulas)

So, I'll take away from this the lesson to always have a feedback panel
someplace on any form.
Thanks again,

Jim,
Temporarily add a FeedbackPanel to make sure you are successfully getting
through validation.
There's much too much irrelevant code there (to demonstrate such a
problem),
but I did notice, for instance, that you're using a RequiredTextField which
means that the form must have a value for that field, otherwise the form
processing lifecyle will be cut short - one of the consequences of failing
validation is that onSubmit() will not get called, onError() will.

Can anyone see what I've done wrong?
Here's the HTML: http://pastebin.com/m5b1440a0
Here's Java code: http://pastebin.com/m4a217d31
At line#114, onSubmit is not being called. I've tried lots of different
things - I've tried adding a wicket:id to make it a Link, it gets
execution
flow, but without the model having been updated yet, which isn't really
what
I want. Similarly, I can make it a Button, but that also doesn't get
the
onSubmit.
Any tips for me? I feel like I'm missing something really simple...
Thanks,

Re: Why don't I get onSubmit() for my form?
Thanks to all who helped find this - yes, it was failing to validate my
input numeric 123.45.
I came up with this fix in my application class:
protected IConverterLocator newConverterLocator() {
converterLocator.set(Double.class, new AbstractDecimalConverter() {
private static final long serialVersionUID = 1L;
IConverter delegate = DoubleConverter.INSTANCE;
@Override
public String convertToString(final Object value, Locale locale)
{
return Currency.getInstance(locale).getSymbol() +
super.convertToString(value, locale);
}
@Override
protected Class getTargetType() {
return Double.class;
}
public Object convertToObject(String value, Locale locale) {
if (value != null
value.startsWith(Currency.getInstance(locale).getSymbol()))
value = value.substring(1);
return delegate.convertToObject(value, locale);
}
});
Thanks,
-- Jim.

Basic print.css question
Sorry this isn't so wicket specific, but I think I'm doing this media type
thing correctly - what am I missing? Here's the view-source of my wicket
page:
head
titleFirst Unitarian Universalist Church of Columbus Auction 2009/title
link href=app.css rel=stylesheet type=text/css media=all/
link href=print.css rel=stylesheet type=text/css media=print/
/head

href=?wicket:bookmarkablePage=:org.firstuucolumbus.auction.page.StatementPageMy
Statement/a/li
/wicket:link
/ul
span class=noprint wicket:id=helloWelcome Jim Pinkham/span
yadda yadda yadda.
For some reason, when I do print-preview, I'm still seeing the ul
id=navlist element and the last line span class=noprint ... Welcome
...
app.css and print.css are in the same folder, and print.css starts with:
div#footer ul#navlist, #noprint
{
display: none;
}
All the app.css styles are applied properly, but the display:none doesn't
seem to be taking effect on the class=noprint or the ul#navlist.
Thanks,

Inmethod grid with more edit controls
I'm just getting started with inmethod grid and loving what it does so far. Now I'd like some to use other input controls such as checkbox, radiobutton, datepicker, or ChoiceList. I see EditablePropertyColumn has newCellPanel I could override to return Panels with various input component types in edit mode. Before I embark on this, does anyone have other ideas about how to approach this? Panels could benefit from the way TextFieldPanel puts feedback into title, which suggests to me a new class such as AbstractEditablePropertyColumn where this could be moved. I also notice that CheckBoxColumn has the concern of being a row-selector that could be separated into RowSelectingCheckBoxColumn, for example (leaving the name CheckBoxColumn available as the obvious choice for editing any boolean column). I also like the idea of the light-weight propertycolumn (currently newCell just puts value into response) to use these same corresponding panels in disabled mode - maybe for radio and checkbox render the corresponding control markup as disabled (display-only) to retain the light-weightness but also have a richer display. I know that's a lot to ask, but it seems a reasonable target to aim for... Thoughts? Thanks, -- Jim.
Re: Inmethod Grid with wicket 1.3
Nice.
OK, now I'm getting more ideas - I added more columns, but now I'd like some
to use other input controls such as checkbox, radiobutton, datepicker, or
ChoiceList.
I see EditablePropertyColumn has newCellPanel I could override to return
Panels with various input component types in edit mode.
Before I embark on this, perhaps you have some ideas to share about this?
If there is some minor refactoring involved, I'm not afraid to jump in and
help if it also benefits others.
For example, these Panels could benefit from the way TextFieldPanel puts
feedback into title, which suggests to me a new class such as
AbstractEditablePropertyColumn where this could be moved. I also notice
that CheckBoxColumn has the concern of being a row-selector that could be
separated into RowSelectingCheckBoxColumn, for example (leaving the name
CheckBoxColumn available as the obvious choice for editing any boolean
column).
That could be step one, then once that works, the next step could be for the
light-weight propertycolumn (currently newCell just puts value into
response) to use these same corresponding panels in disabled mode.
I know that's a lot to ask, but it seems a reasonable next level to aim
for... Thoughts?
Thanks,
-- Jim.

If you don't use multiple select than you can override

Got that working. Now, since I'm using row selection to indicate

one-at-a-time), I'd like to give the checkbox column a header: new

override getHeaderModel, but isVisible is false in the HeadPanel.
Can I visit the component by attribute name somehow to do it?
Really appreciate the help - it's starting to look good. Since I'm
using a pageSize of 500, avoiding the page refresh allows me to have
super-simple yet snappy interface for non web-savvy proofreaders.

If you want to save the entity, SubmitCancelColumn is indeed the right
place. but you should be overriding the onSubmitted method. As for
custom delete link in SubmitCancelColumn, that might be a bit
problematic as the panel is package private.
Anyway, I usually don't put the delete link in that column, it doesn't
make much sense IMHO. WhatI do is to add CheckBoxColumn and a separate
delete link that removes all checked items.

I think the IDataSource is very clear, but it is for loading. For
updating, is this appropriate, or am I overlooking a simpler/better
way?
Then, I would like to add a delete link inside the SubmitCancelColumn
- has anyone already done that? I'm thinking it would only be visible
if editMode is false to share the same screen space with the ok/cancel
icons.
I suppose a blank line to add a new row at the end would be nice too,
but I think I can figure that out myself...
