Re: Tapestry5 and SEO

Good points. There are two conflicting demands from the community:
First, that everything should work, and work well (and fast) out of

When resolving such conflicts, I will tend to favor the first (work
and work well with no configuration) over the second.
That being said, it would be nice if we could handle a few of these
cases better or easier: for example, something more automatic in terms
of detecting a 404 inside the Index page's activation context, or some
other mechanism to easily distinguish proper page render requests
(with context) from link garbage.
Please don't get me wrong. I totally agree with your point that First,
that everything should work.

Just a few finding while doing SEO for a t5 app:
1. activation context and Index pages
The root Index page of the t5 webapp catches a lot of requests that
otherwise would have been a 404. (already discussed on the list).
For our website that means: there are many pages in the google index that
have gone a long time ago. But because T5 simply activates the root Index
page for those google spider requests, google now finds the start page and
reindexes the gone page with the homepage contents. Not quite lucky.
Quick workaround: check the root Index page's activation context:
Object onActivate(EventContext ctx){
if(ctx.getCount() == 0)
return null;
// handle bad requests,
return Document404.class; // does the not found details
}
2. Pages with .php extensions
Our public website was a PHP application before we replaced it with our new
shiny t5 app. So google had a lot of URLs like .../index.php?id=222 in it's
index.
When we switched to t5 and google respidered our website, those requests
failed instead of a proper 404 was thrown. Why? Because our Index page did
not contain a component named php
Quick workaround:
Object onActionFromPhp() {
return Fehler404.class;
}
3. Lowercasing of Page Names
When T5 redirects, page names, component names (, ...?) all become
lowercase. I wish that T5 in it's default settings would preserve the case
used in originating URLs
Does this actually affect SEO?
No, I don't think so. Just a matter of personal preference.
4. I wish, T5 would allow underscores, so that my page named DailyEvents
could have a URL like daily_events
As we add more and more and more of these special cases, it gets
harder and harder to talk authoritatively about what Tapestry will do,
and it becomes increasingly impossible for 3rd party tools (such as
IDE plugins) to operate. Name your class Daily_Events.
Sounds reasonable. I didn't even think about third party tools at first.
5. I wish that T5 in it's default setting would allow daily_events.html in
it's default settings as page name for the same page as in the example
above.
This is frequently requested ... is there a JIRA issue for it (hint)?
https://issues.apache.org/jira/browse/TAP5-771
I know that T5 URL handling is highly customizable. I wish I had the time to
look into that.
Well, if SEO is that important to your bottom line, you probably should.
Sooner or later I'll will. Unfortunatly my workload doesn't allow it
right now.
What do you think? Or do you have other findings with regards to SEO?
Andy
So far, my contacts who do SEO are quite happy with Tapestry, though
they created an override to hack .html into the URLs.
As I said: There are quite easy workaround for most of these points. And
in your answer you suggested even more...

Re: Is tapestry the right for me?
That sounds fine. :) After some further reading i will try something around with the grid component. Is it (again) possible without JSF-like terror to combine grid and form? What i need to have is the possibility to setup a grid with e.g. select components in the cells. (first column labels, 2..n columns form components). This form should be generated on server-side, i prefer the non-ajax way.

Re: Re: ActionLink in bundle message
Hi Kai,
instead of ActionLink use EventLink, if you can.
The tml would look like:
a href=# t:type=EventLink event=detailLink t:context=literal:1more/a
a href=# t:type=EventLink event=detailLink
t:context=literal:2more/a
I´d use a more eventish name for the event. How about detailClicked?

You don't need a component id to handle its event: just handle the

If you create more than one event link this way, generate their links

Testify + Testng
I have been playing with Testng and the Testify library but i am
having a small issue. It seems that the injection of services occurs
after the @BeforeSuite.
For example in the following code, defaultDataCommandManager is null
when the test enters the BeforeSuite method. However the property is
injected once the test started to be executed.
@Inject
private DefaultDataCommandManager _defaultDataCommandManager;
@BeforeSuite
public void initData(){
_defaultDataCommandManager.populateDefaultData(); //property is null
}
@Test
public void initData(){
_defaultDataCommandManager.populateDefaultData(); //property is not null
}

Re: [T5.0.18] Bug? : Null property problem with the custom component inside a grid
Hi Howard, In fact, if you look at the rendered URL you'll see that every time the Image component rendered, it rendered the same URL. Yes, it's always the same image (the last one) in grid component. The solution is to use event context to identify the book, or in some other way, identify where the data stream is supposed to come from. Sorry, but i can't figured this out. Perhaps you can elaborate the solution? Here is the relevant code: [ http://www.nabble.com/-T5.1--Using-a-custom-image-component-inside-a-Grid-td24421215s302.html]http://www.nabble.com/-T5.1--Using-a-custom-image-component-inside-a-Grid-td24421215s302.html Regards, Marcus Veloso
Injecting Tapestry services into Spring beans
Hi everybody,
I'm trying to inject two services from Tapestry-Spring-Security into a
Spring bean, using Tapestry 5.1.0.5 and Spring 2.5.6-SEC01.
The way I think this should work is this:
public class PasswordChangeServiceImpl implements PasswordChangeService {
@Inject
private SaltSourceService saltSource;
@Inject
private PasswordEncoder passwordEncoder;
...
private String createPasswordHash(String plainTextPass) {
UserDetails userDetails = ...
Object salt = this.saltSource.getSalt(userDetails);
return this.passwordEncoder.encodePassword(plainTextPass,
salt);
}
}
and
bean id=passwordChangeService class=PasswordChangeServiceImpl
...(other dependencies)...
/bean
I inject the service instance into my page using the @Inject annotation:
public class UserProfile {
@Inject private PasswordChangeService passwordChangeService;
...
}
The service is properly configured as far as the dependencies handled by
Spring are concerned, but the two services that I'd like to be injected from
Tapestry's IoC newer make it into the instance, and I get a
NullPointerException when they are accessed.
Both SaltSourceService and PasswordEncoder are defined and visible on the
service status page, and they work like a charm when injected into
components directly. I'm not using 5.0 compatibility mode.
Does anyone have an idea what I am missing?
Thanks

Stale sessions and recovering from same in T4.1.6
Hi,I'm looking for a little guidance on how to solve the following problem. *First the description:* The first thing to note, is that our apps all live behind SiteMinder, so that when a users arrives at our application they have already been through the credential validation process and the remote_users request header has their valid userId. I have two related Applications. AppI and AppM. Each App allows a group of users to CRUD a set of Documents. The users enter the app, and are presented with a Queue of Documents presented as a table. The first column of that table for the AppM workers is an identifier for the document wrapped in a DirectLink. When they click on that identifier (anchor), they go to a second page, where they can view or edit the selected document. The second App, AppI does a similar presentation for a different set of Documents, AppI type documents. Click on the direct link and the AppI document is presented to be edited or viewed. Each of these Applications resides in a separate JBOSS container. The latest requirement is that AppI users need a way to view certain AppM documents. There is a read only view of the document in AppM, so the feeling was that the quickest way to give the AppI users a view into AppM documents was to link from AppI to AppM's read only view. AppM links look like: https://appm.ourDomain.com/appM/Home,mNumberLink.sdirect?sp=S1737 In the AppI Queue I coded up a Generic Link that looks just like the links created in AppM. https://appm.ourDomain.com/appM/Home,mNumberLink.sdirect?sp=S1737 *The problem*: The first time the users clicks the link they are sent to a StaleSessionException page. At that point, they are given the choice to click the refresh session page, and then all is good. Subsequent clicks on other links, or the same link always work. I tried to solve the problem with the initial link by creating my own StaleSession page, and in the pagevalidate method find the userId, create a valid user and then throw a page redirect to the same page they were originally going to, but that, has not work. What I need is some idea of how to catch that stale session and restart a fresh new session. I want the first click through to work like all the other click throughs. Tony Giaccone

[T5.1] Coercion/Class mismatch error (a real headbanger)
Hello all,
I'm seeing a very odd behavior I could really use some assistance with.
The base error I'm getting is:
Could not find a coercion from type
com.java.dse.cwp.eos.components.webdesign.objects.Tab to type
com.java.dse.cwp.eos.components.webdesign.objects.Tab.
Which is pretty odd, especially considering that my classpath only contains
one Tab class, and com.java.dse.cwp.eos.components.webdesign.objects.Tab
is it.
Tab is just a container class which essentially has two String members, and
accessors, not that I think this matters.
The issue is reported from Tapestry in a loop component, when I try to loop
over a ListTab returned from this function:
Code:
public ListTab getTabs()
{
if (tabs == null isValidProduct())
{
tabs = new ArrayListTab();
tabs.addAll(product.getTabs());
tabs.add(new Tab(true, Get It /* TODO: put this in
the template! */,
null));
}
return tabs;
}
where 'tab' is a 'ListTab' and 'product.getTabs()' returns a 'ListTab'
I can comment out the line 'tabs.addAll(product.getTabs());' and everything
works (?!?!?) so I think something very odd is going on and the Tab class is
being munged behind the scenes.
The full (well, I truncated it a bit) error/stack is below:

However, how do I get a ClassNameLocator in bind(ServiceBinder)?

Levi, did u try to do what Thiago suggested? The class Tab is not a component therefore it shouldn't be inside the component packet.

Re: [T5.1] Coercion/Class mismatch error (a real headbanger)
Any top-level class under components is considered to be a component and will be loaded in a special class loader. This causes a problem when an instance is created by the normal class loader and passed into a comopnent, which has a distinct Class instance. Create a different package for objects of this type; i.e. com.java.dse.cwp.eos.data.Tab. This is all documented http://tapestry.apache.org/tapestry5.1/guide/reload.html On Fri, Jul 10, 2009 at 3:16 PM, xfile80303l...@grokers.net wrote: The more I look at this the more it looks like a classloader issue.

How to set a meta header tag in template?
I am using tapestry version 5.1.0.3. I have a basic SiteLayout defined html xmlns=http://www.w3.org/1999/xhtml; xmlns:t=http://tapestry.apache.org/schema/tapestry_5_0_0.xsd; head...some css styles.../head body ...some html goes here... t:body/ /body /html Now as someone navigates my site, there is a particular page on which I want to turn off caching (because it always has to get the latest data from the servers on that page). So, lets say I have a page NoCachePage.java and NoCachePage.tml already coded. But the head tag is defined in the Site.tml template. How can I get my http meta tag META HTTP-EQUIV=CACHE-CONTROL CONTENT=NO-CACHE/ into the Site.tml's head element? I tried setting up @CleanUpRender inside NoCachePage.java and tried to manipulate the DOM through the MarkupWriter. But it appears as if MarkupWriter doesn't provide any method of adding an element under the head html tag. How am I supposed to add the no-cache meta http tag into the head element from my NoCachePage component? Please help. -- View this message in context: http://www.nabble.com/How-to-set-a-meta-header-tag-in-template--tp24436287p24436287.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
