I'm back!

[Kalle Korhonen]

Hi all,

just wanted to say hello as I'm back working on Tapestry & Tynamo, at least
for a fleeting moment! It all started when I was brought to steward an
unruly, JSP-based(!) codebase that used Spring ACL as its security
framework. With a few tens of thousand of data rows and a complex security
rules, the ACL join tables were starting to push several millions of rows,
all handled post data query and it was starting to show. So, I figured I'll
dig up some old code (http://www.tynamo.org/tapestry-security-jpa+guide/)
to show how this could be rewritten properly, and the next thing I know,
I've been writing a whole next generation proof-of-concept application in
Tapestry :)

While we are still in Java land, there's a lot to like about Tapestry,
obviously with it's code auto reloading and the sane approach to dependency
injection, but also pseudo nested transactions (the whole transaction
handling is so much more sensible than in Spring) and simple JAX-RS
integration. On that note, one of the new modules I published was a swagger
integration for tapestry-resteasy. Overall, this weekend saw releases of no
less than seven Tynamo modules, all updated to work with Tapestry 5.5:
tapestry-conversations 0.3.0
tapestry-jpa-seedentity 0.2.0
tapestry-security 0.8.0
tapestry-security-jpa 0.2.0
tapestry-resteasy 0.6.0
tapestry-resteasy-swagger 0.0.2
tynamo-test 0.2.1

You may check out the updated documentation at http://www.tynamo.org/ as
always. I'll post a few announcements as time allows.

Re: Single Page Application

[Kalle Korhonen]

I've done SPAs with Tapestry but more recently, I've gone over the "dark
side" to develop SPAs with Clojure. I re-implemented one Tapestry+Ember
project as a functionally equivalent Clojure app, and I just posted
lines-of-code comparison plus other notes about it (
http://www.tynamo.org/2018/07/02/arbitrarily-complex-uis/). In short, while
you can implement SPAs with Tapestry, there are more productive options
just for that purpose.

tapestry-security 0.7.1 and tapestry-resteasy 0.5.0 released!

[Kalle Korhonen]

It's that time of the year again. Actually, the community has been asking
these to be released for a while. Thanks to @homburgs, you can now
contribute chains with RegExPatternMatcher to tapestry-security (
https://github.com/tynamo/tapestry-security/pull/50). Also, 0.7.1 is now
using the latest version of Tapestry and I cleaned up a few annoying
default configuration errors that used to pop up in the logs(
https://github.com/tynamo/tapestry-security/issues/49). See docs for
tapestry-security for more (http://www.tynamo.org/tapestry-security+guide/).

Tapestry-resteasy 0.5.0 now comes with the latest version of Tapestry and
resteasy (3.1.4.Final) as well. Thanks to @jochenberger for tirelessly
keeping the versions in sync. See docs for tapestry-resteasy for more (
http://www.tynamo.org/tapestry-resteasy+guide/).

As a side-note, while our Maven & OSS (
https://www.sonatype.com/nexus-repository-oss) based release process has
worked well for the community for years, it does feel clunky and almost
pointless for those of us who've ever used Bintray's Github-based release
"process"(
https://blog.bintray.com/2013/06/05/bintray-github-synergistic-love-story/).
Using Bintray also nicely solves the problem of building snapshots since
you can use git(hub) hash as a version in case you need access to some
unreleased features. I don't know if I have appetite to make changes to
move over though, given that most of our libraries are pretty mature and
slow moving at this point. Anyhow, something to keep in mind in case we
come up with a brand new module.

Enjoy!

Re: Access request from tml / standard servlet api role support

Tapestry-security (http://www.tynamo.org/tapestry-security+guide/) supports
request.isuserInRole and provides components similar to the one suggested,
i.e.

Re: Override BeanEditForm Submit Button

[Kalle Korhonen]

You want to use the underlying BeanEditor component that does most of the
work and build your own form around it, could start by copying the
BeanEditForm source:
https://github.com/apache/tapestry-5/blob/master/tapestry-core/src/main/resources/org/apache/tapestry5/corelib/components/BeanEditForm.tml

Re: "Detached entity passed to persist"

[Kalle Korhonen]

Surprisingly, this (re-attaching a detached entity) is not a simple
problem. First of all, you need to be very careful about holding onto
entities in your session. It's too easy with JPA/Hibernate to accidentally
keep the whole query resultset in memory when you think you are holding
onto a single object (check with your jvisualvm). Second, since you are
using Hibernate, you can re-attach an entity with (the now deprecated
operation) session.lock(entity, LockMode.NONE), not absolutely sure how the
latest versions behave. I've written about it at
http://www.tynamo.org/tapestry-conversations+guide/, referencing this
stackoverflow issue about it:
https://stackoverflow.com/questions/912659/what-is-the-proper-way-to-re-attach-detached-objects-in-hibernate,
make sure you read all of it. Your best bet is to only store the company id
in the session and do a find() before setting the company (I know, it
defeats some of the perceived user benefits of using Hibernate/JPA).

Re: Authorisation in Tapestry Applications

[Kalle Korhonen]

Attachments don't come through to the mailing list but so you have a table
that describes permissions for all of the entities? Obviously, visually
showing or hiding buttons on the client doesn't really enforce security but
you are right, Tynamo doesn't really offer anything for this case out of
the box. It'd relatively easy to write custom security annotations for your
case though, for example following the source code in tapesty-security-jpa
(see http://www.tynamo.org/tapestry-security-jpa+guide/). On the other
hand, if you used the same CRUD pages for all your entities (similar to
http://www.tynamo.org/tapestry-model+guide/), you'd only need to implement
the security checks in one place, making annotations quite useless. It all
depends on how complex your data is and how customizable you need your
pages to be. If you have a lot of entities but it editing the data is
mainly form-based, I'd almost encourage you to take a look at
tapestry-model and how well that would work for you. There's a fair bit to
learn there if you need to customize the pages heavily but it could give
you a lot for free, including having the security checks all in on page
(both visually and at the data level).

tapestry-security 0.7.0 released!

[Kalle Korhonen]

After an extended hiatus, I figured it’s time to do some releases. First up
is the old workhorse, tapestry-security. The 0.7.0 release represents a
true community effort, my job was mainly to merge pull requests from
multiple authors. Thank you @jochenberger, @fkretzer, @pedrocborges2,
@ascandroli, @bobharner! We are all updated to use the latest Shiro and
Tapestry 5.4, with a host of important fixes and even a few new features.
To highlight one of them, see #40 add facility to remove/add/update
security chains at runtime
, from
@jochenberger. Note that there was one breaking change made as part of this
issue - The contribution to SecurityConfiguration was changed to
OrderedConfiguration, so you need to name all your contributions. See
examples in the  documentation (
http://www.tynamo.org/tapestry-security+guide/). Thanks to all and enjoy!

Re: Tapestry-security CacheManager

[Kalle Korhonen]

Typically, you'd set the desired cachemanager in the realm itself, e.g.:

public class UserRealm extends AuthorizingRealm {
public UserRealm(...) {
super(new MemoryConstrainedCacheManager());

(You could override but) don't try to customize it, instead just create

Re: Tynamo Security Login Page

Need to specify the library since it's not your own component - loginPage
is just a local attribute name. Use  or
just replace the whole block with <:tsecurity.loginlink>.

Re: Tynamo Security w/ custom Realm

Looks fine at a quick glance. As I recall, an AuthenticatingRealm uses
SimpleCredentialsMatcher by so it should match plain text passwords. Are
you sure it's not authenticating, or is doGetAuthenticationInfo invoked at
all? Do you have any other realms configured? Get the simple, single realm
use case working first and work from there.

Re: WebSocket enpoint as a tapestry service

[Kalle Korhonen]

It's relatively simple like Cezary says. The only potential issue is with
authenticating JSR 356 websockets, which may require a bit of gymnastics
depending on your needs. If you are using sessions, you can fetch
underlying (servlet) session from the handshake request (see
http://stackoverflow.com/questions/21888425/accessing-servletcontext-and-httpsession-in-onmessage-of-a-jsr-356-serverendpo/27057359).
If you are using sessionless authentication (w/ JWT), you can pass the
bearer token around in the sub-protocol header,
namely Sec-WebSocket-Protocol (see
http://stackoverflow.com/questions/22383089/is-it-possible-to-use-bearer-authentication-for-websocket-upgrade-requests/35108078
).

Re: tapestry-hibernate + tapestry-cdi

[Kalle Korhonen]

AFAIK, tapestry-hibernate simply doesn't support it. However, is switching
to JPA an option? You could still be using Hibernate as the provider.
tapestry-jpa merrily supports multi tenancy (and more). If JPA is not an
option, I'd look into implementing your own custom @Session - may not be
too bad - there isn't that much code in tapestry-hibernate. That would
resolve the version mismatch - since Hibernate is pretty finicky about it,
you could just build against the version of your choice.

Re: tapestry5.4 + hibernate + postgres + postgis

[Kalle Korhonen]

Might be enough to downgrade your JRE to 1.7, or, need to use the exact
version of Hibernate that is compatible with tapestry-hibernate. If you
need to use a newer Hibernate with Java 8, compile and deploy the
tapestry-hibernate version from T5.5 master yourself.

Re: Tapestry launch a JEE 7 webservice?

[Kalle Korhonen]

Yes, use tapestry-resteasy (http://www.tynamo.org/tapestry-resteasy+guide/).
You wouldn't need an explicit subclass of Application, but you'd configure
your resources with:

@Contribute(javax.ws.rs.core.Application.class)
public static void configureRestResources(Configuration
singletons,
YourRestResource yourRestResource, ... ) {
singletons.add(yourRestResource);
// optionally... CorsFeature implements javax.ws.rs.core.Feature
etc.
singletons.add(new corsFeature());
singletons.add(new JacksonConfig());
singletons.add(new JsonExceptionMapper());
}

As a workaround, perhaps the simplest thing to do is to set your JVM

Re: Null pointer on sort with 5.3.8 that didn't occur with 5.3.7

[Kalle Korhonen]

I suspect the culprit is the Java upgrade rather than Tapestry. There are
some internal changes in the sorting algorithm (for example, see
https://bugs.openjdk.java.net/browse/JDK-8062797 although it doesn't
directly match your case). But basically, you have to make sure your grid
data source doesn't contain null values, or you feed a comparator to it
that can handle nulls.

Re: http redirection to https port 443

[Kalle Korhonen]

No need to override BaseURLSource. You can just configure
SymbolConstants.HOSTPORT_SECURE to 443. The default is 0, which means use
request.serverPort. I'd say you are missing something from Jetty
configuration, since you are getting that port from the request, but add a
breakpoint to BaseURLSourceImpl.portExtension(..) and see how it behaves.

tapestry-security 0.6.4 release addresses a serious vulnerability

[Kalle Korhonen]

While the Apache Shiro team (me included) are still mulling over how to
best fix a serious security vulnerability with Shiro's default rememberMe
cookies and object deserialization [SHIRO-550](
https://issues.apache.org/jira/browse/SHIRO-550), I went ahead and
implemented a fix for the vulnerability in [tapestry-security](
http://www.tynamo.org/tapestry-security+guide/), following a similar
approach I had proposed for Shiro as well. In essence, an attacker can
potentially gain access to the server using a deserialization vulnerability
(see more at
https://www.contrastsecurity.com/security-influencers/java-serialization-vulnerability-threatens-millions-of-applications
). It's a bit more convoluted for Shiro in general, but once again, service
contributions make this a simple matter to handle in Tapestry. In 0.6.4 of
tapestry-security, only known principal types can be deserialized. *Long*,
*Integer* and *String* (which likely cover 99% of the use cases) are
sanctioned by default and users can easily contribute additional principal
types to the org.apache.shiro.io.Serializer service, for example:

```
@Contribute(Serializer.class)
public static void addSafePrincipalTypes(Configuration
configuration) {
configuration.add(UID.class);
}
```

You are advised to update immediately. Currently the fix is only available
for Tapestry 5.4 but I'll make other releases available as requested. You
can also easily copy the relevant classes from the [source tree](
https://github.com/tynamo/tapestry-security/blob/master/src/main/java/org/tynamo/security/shiro/SimplePrincipalSerializer.java)
and override services as needed in your application.

**Release notes**

- Upgrade Shiro to 1.2.5 [#26](
https://github.com/tynamo/tapestry-security/issues/26)
- Safely deserialize principals from rememberMe cookie  [#27](
https://github.com/tynamo/tapestry-security/issues/27)
- Update to Tapestry 5.4.1 [#28](
https://github.com/tynamo/tapestry-security/issues/28)

Re: Overriding and translating JSR-303 validation messages

[Kalle Korhonen]

You should be able to override them by adding a
ValidationMessages.properties file at the root of your classpath. See
https://github.com/apache/tapestry-5/blob/master/tapestry-beanvalidator/src/test/resources/ValidationMessages_en.properties
for examples.

Re: how to define a new asset domain

[Kalle Korhonen]

In Tomcat, you'd just drop in a new context.xml and specify a docBase
attribute in it (see
http://stackoverflow.com/questions/1812244/simplest-way-to-serve-static-data-from-outside-the-application-server-in-a-java).
Jetty had something similar, see their docs.

Re: how to define a new asset domain

[Kalle Korhonen]

If you are serving static files but want to keep the deployment simple,
it's very straight forwarded to set up a new context, such as /images/ to
purely serve static resources. I've done it in a few occasions and the nice
thing about it is that you don't really need more than one liner in an xml
file and you can configure the resource "webapplication" with very
aggressive caching settings (at least Tomcat allows caching and serving
everything from memory).

Most likely, you have a permgen memory leak. Are you using streams and/or
threads on your pages and are they properly closed, even in case of
exceptions? I can't tell you how many memory leaks I've plugged over the
years in thread and stream handling. Invariably, the errors are in your own
code. See https://plumbr.eu/blog/memory-leaks/what-is-a-permgen-leak for
possible causes for a permgen memory leak. Also, you are in luck because
Tomcat 6 added some useful tools for detecting memory leaks (see
http://wiki.apache.org/tomcat/MemoryLeakProtection, and Tomcat 7 and up is
even able to recover from some of them). Take a heap dump of the stressed
out system and load it in your VisualVM.

Re: tapestry 4.1.6 and pergmen question

[Kalle Korhonen]

If you run out of permgen space very quickly, then it's indicative that the
allocated permgen space is simply too small. Perhaps the new version of
Tomcat requires more of it for itself, leaving less for your application.
Is the webapp restarted at times? If so, that can easily cause permgen
space to fill up because of the way OGNL works. And even if you are not
restarting the app, you need to exercise all parts of your web application
to find out the true permgen space consumption of it.

SecurityAssert is your own code right? What are you injecting into it and

Re: Tapestry 5.3.7 with Tanuki service wrapper

[Kalle Korhonen]

I've used Tanuki to wrap various versions of Tapestry webapps and I've also
done plenty of embedded Jetty/Tomcat installations. Never had any major
issues with Tanuki. Any problems are almost always related to classloader
issues, not directly caused by Tanuki.

Re: Hibernate call returns wrong day

[Kalle Korhonen]

The same thread really reads the same value from the database every few
seconds and it may come out different? I don't buy it, there must be
something else going on at the same time. Are you sure it's the same value?
Is there something else writing to it at the same time? Can the system
default timezone change (perhaps also print out TimeZone.getDefault(), Date
initialized to the default timezone). I'd still suspect some type of
timezone issue.

Re: OAuth2 Server tapestry implementation

I don't see a reason to do a plain servlet implementation if it's not for
educational reasons only. JAX-RS or even a Tapestry API would serve you
much better as an Oauth endpoint.

Re: OAuth2 Server tapestry implementation

[Kalle Korhonen]

Adapting the code from Oltu's integration tests (e.g. see
https://github.com/apache/oltu/blob/trunk/oauth-2.0/integration-tests/src/test/java/org/apache/oltu/oauth2/integration/endpoints/AuthzEndpoint.java),
it should be relatively simple to implement Oauth authorization & resource
servers as JAX-RS endpoints with Tynamo's tapestry-resteasy (
http://www.tynamo.org/tapestry-resteasy+guide/). Tynamo-federatedaccounts
can certainly be used as a a client to your own server with some
customization. It's not too difficult, but previous knowledge on basic
Oauth workflow and JAX-RS is required. I'd love to make this much simpler
really but there are lots and lots of options how you want things to behave
so one size doesn't fit all.

One of the more interesting things in authorization space I've been working
on lately is invoking an Oauth request with a third-party authorization
server from an Ember client, then validating the access token through my
own service, federating it with a local account and finally returning JWTs
for sessionless *and* using the same tokens for authorizing websocket
connections. Phew. I may try to spin some parts of it off to an open source
library but not quite sure yet what exactly would make a good reusable
module.

Re: TAPESTRY-1908

[Kalle Korhonen]

I suspect you are talking about
https://issues.apache.org/jira/browse/TAPESTRY-1908 instead of
https://issues.apache.org/jira/browse/TAP5-1908? The actively worked T5
issues are in the TAP5 namespace. The former is a *nine years* old issue
with a sample code to get it to do what you want. Furthermore, the beanType
can by all means determined at runtime, that's exactly how Tynamo's
tapestry-model (http://www.tynamo.org/tapestry-model+guide/) works.
Object.getClass() works only for the simplest cases. Quite often you want
to specify an interface as the beanType for your model.

The obvious choice is to manually commit the transaction, then notify the
observers. @CommitAfter is fine for simple cases but if the transaction is
rolled back, it doesn't allow you to react to it. If you still prefer
annotation, you could try out
https://github.com/satago/tapestry-jpa-transactions that support pre/after
commit hooks.

Re: Save File Dialog after response building

[Kalle Korhonen]

Yes, so if you respond to an ajax request with a page response, T5 will
send you a json snippet {"redirectURL" : "your.redirect.url"} and handles
redirecting to it from the client. In this case you are responding with a
StreamResponse so T5 gets confused. If you wanted to do an ajax update,
it's totally possible. You just need to move your StreamResponse to a new
page and return (a link to) this page from your event handler. The possible
advantage is that you can have testable download urls for your files, like
/downloadfile/somefile.tmp.

The DownloadFile page would simply contain something like this:

public class DownloadFile {
StreamResponse onActivate(String fileId) throws IOException {
return new StreamResponse() {...}
}
}

Your event handler should return a page object or an URL, check
http://tapestry.apache.org/page-navigation.html for more info.

For Eclipse, you want to install Dmitry Gusev's excellent Tapestry plugin
https://github.com/anjlab/eclipse-tapestry5-plugin.

By the way, I agree with your comments about javascript documentation. It's
great if you've been working with Javascript and AMD modules before, but
totally lost if you haven't.

Yes Chris is right (see
https://github.com/apache/tapestry-5/blob/master/tapestry-hibernate/src/main/java/org/apache/tapestry5/internal/hibernate/CommitAfterWorker.java),
you need to depend on tapestry-hibernate. tapestry-hibernate-core is for
non-web projects (where you need the advisor to tell to ioc when to commit).

Tapestry-conversations 0.2.0 released!

[Kalle Korhonen]

We aim to serve. A user asked for a T5.4 compatible version of
conversations module and we delivered. Upgrading the module was pure joy
and it is a testament to the outstanding backwards compatibility record T5
has had throughout its existence. Note that I had written the original
version for Tapestry 5.0 while we were still called the Trails framework!
Checkout the http://www.tynamo.org/tapestry-conversations+guide/ for more
info.

**Release notes**

- Update to tapestry 5.4 [#1](
https://github.com/tynamo/tapestry-conversations/issues/1)

Re: registry startup issue

[Kalle Korhonen]

You are using a version of plastic that's incompatible with the version of
tapestry-core and/or JVM you are using. Check your classpath for multiple
version of these libs. It's always a good idea to state upfront the
versions you are using to save others from the guesswork.

Re: maven build dependency problems

[Kalle Korhonen]

kaptcha 2.3 is still available from Sonatype's forge repo at
https://repository.sonatype.org/content/groups/forge/com/google/code/kaptcha/kaptcha/2.3/.


T5.3 needs to depend on that version because it is the last version still
built with jdk1.5.

However, T5.4 switched to https://github.com/axet/kaptcha and as I recall,
it was a drop-in replacement so it should work for T5.3 as well (that is if
you are not limited to Java 1.5 yourself).

Re: maven build dependency problems

[Kalle Korhonen]

No, I think you should remove extra repository references. Codehaus went
bust more than 8 months ago. Track down where codehaus repo is being
referenced and remove it. If you need the org.got5.tapestr5-jquery library,
use the versions available at Maven central:
http://repo1.maven.org/maven2/org/got5/tapestry5-jquery/

Re: T5.3.8 ClassNotFound error ONLY when running on a virtualized server?!

[Kalle Korhonen]

In my experience, the "weird errors" you see in virtualized production
environments where JVM is unrestricted (unlike Google App Engine or RedHat
OpenShift) are almost never caused by the environment itself but some
small, fairly simple differences between your dev/test and production
environments. "Unable to locate class" is almost certainly caused by
Plastic not being able to instantiate your custom exception report page.
Could be a small missing dependency or anything else but errors that happen
in the exception handling chain are not always clearly reported, and this
case "not able to locate" is probably a bit misleading when that class
likely threw an exception while being instantiated.

For the actual error at JobHistoryManager.java:429, why would you even post
this without sharing the code with us? I guarantee it's not just because
its "somehow not liking the virtualized server" but without seeing the
code, all we can do is guess.

Re: T5.4 and OLD Hibernate 3x

[Kalle Korhonen]

You could try backing out the tapestry-hibernate and
tapestry-hibernate-core libs to a T5.4 version before beta-17 (see
http://markmail.org/message/yeqlybz6hivwwcxk#query:+page:1+mid:ahfcfibfff2t6ueu+state:results).
They were not available via Maven central and the staging repos are not
available anymore so you'd have to build from the tag yourself. No
guarantee that it'd work but there were fairly few changes (I know because
I did the update originally).

The 4.x Hibernate update was committed to the main branch over three
years(!) ago, so if I were you, I'd just bite the bullet and update to
Hibernate 4.x. I know, it always sucks upgrade several libs at once.

Re: Zone Update with POST

[Kalle Korhonen]

For handling POST, I'd utilize Tynamo's tapestry-resteasy (
http://www.tynamo.org/tapestry-resteasy+guide/). JS could be something like
this:

$.ajax({
   url: 'http://my.server.com/editor/save',
   data: data,
   error: function() {
   },
   dataType: 'json',
   success: function(data) {
   },
   type: 'POST'});

JAX-WS EditorResourceImpl.java:

@Path("/editor")
public class EditorResourceImpl implements EditorResource {
@Path("/save")
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
@CommitAfter
public Map saveContents(EditorContents contents) {
...
}
}

Is it Tapestry or Java that doesn't quite fit well? Having been using
JAX-RS (via tapestry-resteasy of course) paired with an Ember frontend now
for some months, JAX-RS always feels a bit cumbersome and never quite
fitting. Some of the fault is with Ember and it's modules though (but after
Ember's clear and predictable roadmap, ember-cli and friends, I'm not going
back to Angular). But even still, I can see why node.js is a popular choice
as the back-end for the single page apps.

For me personally, I'd love to use a different framework for building web
apps if it was better. The problem with most other contenders I've tried is
that they are nowhere near as comprehensive as Tapestry. They may shine in
some areas but often horribly lack in others.

Sometimes it's the language itself. I've always hated Java's syntax (coming
from Delphi, Smalltalk background) but I just don't get how people get by
without actual threads. Certainly there are many infoapps that merely
input/output data but as soon as you start doing some real number
crunching, it better run on the background and in parallel. I've seen so
many RoR and Python implementation that started out clean and small, then
somewhere along the way required one other service for this and another
service for that, deploying some C libraries, perhaps a few front-end
servers for scalability etc. etc. and before you know it, the time of all
of your engineers is spent on debugging some weird issues that nobody
really fully understands.

Even if it's not the complexity that causes dislike in me, it's the
performance. Nowadays, you can always "just spin up another instance" but
nobody ever thinks about the cost. In a fairly recent case (based on T5.3),
we were serving 17,000 requests/minute at peak times from a single node for
pennies on the dollar. I've seen a VC-backed startup serving 10,000
requests per day on a Heroku deployed RoR implementation and paying
$400/month for it. Compared to personnel and other costs, of course it's
peanuts but I just hate to imagine what something like that costs if it
ever became truly popular.

Anyhow, I guess you mainly wanted comments about the single page apps, not
about infrastructure. I return to the issue with deployment complexity.
Often the single page app still need supporting "static" pages, except
these pages are never quite static. They need common templates, perhaps a
little dynamic section here, up-to-date information there and so it goes...
Of course, you are always free to a totally different tool for these pages
but what I like in Tapestry is that you can do it all with it.

I'd love to know if there's another web framework that has built-in support
for common design patterns and makes it possible to easily implement
aspects like tapestry-security-jpa (
http://www.tynamo.org/tapestry-security-jpa+guide/). A lot in Tapestry is
just for dealing with Java's rigidity and certainly in languages like Ruby
or Javascript, you can always hack stuff together but too often, it quickly
becomes a huge, messy hairball when there's less structure.

Re: [ANNOUNCE] Apache Tapestry 5.4

No, T5.4 was still firmly headed by Howard. He created the first T5.4
branch over three years (see for example
http://tapestryjava.blogspot.com/2012/10/zeroing-in-on-tapestry-54.html)
and you can see the results of his mastermind everywhere in the T5.4 code.
I guess you could say it was the first release not finished by Howard.

Tapestry-security 0.6.3 and tapestry-model 0.6.0 for T5.4 released!

[Kalle Korhonen]

Hey all,

at this time we have two T5.4 compatible release announcements to make.
First tapestry-security 0.6.3:

While working on securing an Ember frontend with Tapestry backend, I
noticed that tynamo-resteasy didn't want to play well with security. I'm
fairly surprised this issue surfaced only now because tapestry-security is
fairly well battle tested. Anyhow, if you've ever had a problem with T5.4
and tapestry-security not being able obtain assigned roles or user identity
from the request, it's time to upgrade.

**Release notes**

- Update to T5.4-rc-1 [#25](
https://github.com/tynamo/tapestry-security/issues/25)
- Store ShiroHttpServletRequest to RequestGlobals before processing [#24](
https://github.com/tynamo/tapestry-security/issues/24)

---
tapestry-model 0.6.0:

Finally, we have an officially compatible release tapestry-model for T5.4
available. We had one long running issue with the changes in tapestry core
and it wasn't until T5.4-rc1 before it was all sorted out. The official
release note is short but there's been lots of great functional changes to
the core.

**Release notes**

- Fix the test suite to use changed form element names [#4](
https://github.com/tynamo/tapestry-model/issues/4)
- 0.5.2 has a dependency on eclipselink [#2](
https://github.com/tynamo/tapestry-model/issues/2)

Happy holidays,
from your friendly Tynamo team

I've mentioned something about it earlier in this message thread and there
was a different thread on it as well where Andreas Andreou shared his
experiences. Because of the ember-cli, and all the pretty cool transpiling,
minifying etc. tools, I really wouldn't try to embed the Ember scripts into
a T5 app but make it a separate app and run them together. It's easy to
package an ember app into .war if you need to - basically just zip up the
contents of /dist. Then just deploy those two wars together. The only other
thing you need to take care of is that the two applications can talk to
each other by adding the right CORS+CSP headers (see
https://en.wikipedia.org/wiki/Cross-origin_resource_sharing for more). If
you really wanted embed the scripts into a T5 application, I'd just
contribute the two different js files, the .js and vendor.js that
Ember spits out at the end as Javascript modules but I'd say developing
them together is too clunky that way.

Re: Frontend Frameworks / Libraries

[Kalle Korhonen]

React and Ember Fastboot solve the SEO problem by rendering the first load
on server, but Angular doesn't offer the same functionality natively.
There's https://prerender.io/ though, but it's another component you need
to deploy.

If you are on T5.4, you can simply contribute an exception type -> error
page map to the DefaultRequestExceptionHandler. It handles XHR requests as
well. See

No, that should be it. Are you sure the module is loaded ? You could use
@SubModule to make sure.

I haven't found anything quite as comprehensive for Ember. One issue with
Ember is that many of these tutorials are outdated because its changed so
fast. The official documentation is often too simplistic when you are new
to it but trying to build something real. However, this one is fairly
up-to-date and helped me quite a bit when I started out:
http://www.fnaweso.me/ember-js-nested-routing-with-multiple-outlets/

At least for me, working with AngularJS feels more like working with T5
services and its IoC whereas working with Ember feels more like writing T5
components and I felt right at home with all the Ember conventions. And
while it's relatively easy to bootstrap AngularJS to run as part of T5 app,
it really doesn't make sense with all the bits and pieces of Ember tooling,
the CLI etc (there was an earlier thread about that and I followed Andreas
Andreou's advice). Ember is more comprehensive than AngularJS and its
router is incredibly useful for mapping out a structure for larger spas.

 perhaps this has to be in app module rather than in my shared jar?


I suspect the HappyModule configuration isn't read at all. That's because
you don't have a manifest when you are reading the classes directly from
the the target path rather than from a jar. Often, you need to explicitly
specify @SubModule(HappyModule.class) (or @ImportModule in T5.4) in your
AppModule when you are developing multiple libraries at the same time (or,
doing integration testing of your modules).

 I've put the hibernate entities that are shared between the projects in
 there and so ideally the code should be in the shared library rather than
 duplicated in both webapps (although it works as it is... any ideas what
 may cause that?)

Re: Advanced transaction support for tapestry JPA applications

Thanks Dmitry, looks excellent. Even so that I don't see any reason we
shouldn't merge this to tapestry's core JPA integration at some point. I
didn't read the code that carefully, but do the injectable JPA
entitylisteners also support (totally non-spec) constructor injection? Do
you know if the corresponding
org.hibernate.jpa.AvailableSettings.CDI_BEAN_MANAGER
is available in EclipseLink configuration and if so, what's the name of the

 1) It overrides @CommitAfter annotation with support for nested calls (only
 top-most method will actually commit transaction)
 2) Simple service for wrapping Runnable/Invokable objects with transactions
 when you need precise control over transactions
 3) Before/after commit callbacks
 4) Support @Injects in entity listeners when used with JPA 2.1

 Please see GitHub readme for details.

 It's built against tapestry 5.3.7, but should also work with latest 5.4

[OT] Hosting

Re: T5.3.7 + Tynamo Security - User ASO creation after authc/authz

[Kalle Korhonen]

On Wed, Apr 29, 2015 at 12:41 PM, Daniel Jue teamp...@gmail.com wrote:

 Hi, I'm getting hung up on something that's probably really simple to fix.
 I have a Tomcat+LDAP configuration that is doing Authc and Authz for
 me--All I have to do is look in the request header to see the user
 principal and log the dude/dudette in.

 So I'm using the built in factory.authc filter on some of my paths that
 need protecting.

 Here's where I'm at:  In the legacy code I have now, the user would have a
 G_User.class ASO created on the Layout component (my own class to hold user
 stuff).  I'd like to move that ASO creation closer to the code where the
 user is deemed authenticated (i.e. outside of a particular component or
 page).   I feel like this is possible, I'm just missing something.

 There's some user class creation stuff going on inside of the
 FederatedAccounts test application UserRealm, but it's not setting an ASO.

 Should I be setting the ASO in a custom Realm or ??


The ASO and authentication are orthogonal concepts. Especially given that
you only have authenticated users in your T5 app, you want to create the
ASO after the user is authenticated.

For the login flow, your hunch is right about looking into
federatedaccounts. However, what you want is to invoke Subject.login by the
time the subject is created by overriding SubjectFactory. Take a look at
https://github.com/tynamo/tynamo-federatedaccounts/blob/master/tynamo-federatedaccounts-rollingtokens/src/main/java/org/tynamo/security/rollingtokens/RollingTokensModule.java
and the accompanying RollingTokenAutoLoginAdvice. That code is more
complicated than you need - you don't have to create an advice but you can
simply override the service (this particular module adds an advice so that
user code can still override the SubjectFactory if needed). Your realm then
handles normal authentication/authorization based on the LdapToken that
your SubjectFactory created (using the request header).

For the ASO, you quite possibly want something like this:

public RequestFilter buildCurrentUserFilter(final UserService
userService,
final ApplicationStateManager applicationStateManager, final
HttpServletRequest servletRequest) {
return new RequestFilter() {
public boolean service(Request request, Response response,
RequestHandler handler) throws IOException {
if (servletRequest.getRemoteUser() != null 
!applicationStateManager.exists(CurrentUser.class)) {
applicationStateManager.get(CurrentUser.class);
}
return handler.service(request, response);
}
};
}

@Contribute(RequestHandler.class)
public void addRequestFilters(OrderedConfigurationRequestFilter
configuration,
@InjectService(currentUserFilter) RequestFilter
currentUserFilter) {
configuration.add(currentUser, currentUserFilter,
after:StoreIntoGlobals);
}

@SuppressWarnings(rawtypes)
@Contribute(ApplicationStateManager.class)
public void addApplicationStateCreators(MappedConfigurationClass,
ApplicationStateContribution configuration,
final HttpServletRequest request, final UserService userService,
final CookieSource cookieSource) {

ApplicationStateCreatorCurrentUser currentUserCreator = new
ApplicationStateCreatorCurrentUser() {
public CurrentUser create() {
return new CurrentUserImpl(userService, cookieSource);
}
};

configuration.add(CurrentUser.class, new
ApplicationStateContribution(session, currentUserCreator));

Re: SSL/TSL for the tapestry tynamo rest

[Kalle Korhonen]

I'm not sure what you mean by mapping the web.xml to the rest pattern but
the easiest scenario is if you want to make your application only TLS
accessible. If your TLS endpoint is application container (Tomcat, Jetty,
etc..) then you just need edit the server configuration files and point it
to your certificate (not the web.xml), for Tomcat see
http://tomcat.apache.org/tomcat-7.0-doc/ssl-howto.html#Configuration. If
you have a http proxy in front (such as Apache Httpd, Nginx) then you need
to do the same configuration there and also let your application container
know that you want to return https urls even if your container sees only
incoming http requests (for Tomcat, you edit the context configuration
files). Tapestry, tynamo-resteasy or tynamo-federatedaccounts barely enter
the picture here. @Secure is only needed if you have a mixed http/https
application (see https://tapestry.apache.org/https.html).

enough to disable SoftReferences and re-run your test. The results may

  The main issue is, that you are able to bring a Tapestry based system

 Fundamentally,
  the

  The

Re: SoftReferences to PageImpl can cause performance problems

[Kalle Korhonen]

A configurable cache might be ok but what Robert is showing is a highly
typical performance degradation pattern for any sufficiently large Java
application. Tapestry's page cache is hardly the only place where soft
references are used. When your memory budget is too small, most system
engineers would argue that it's far better to slow down the application
than OoM, but obviously that depends on the type of application and the
traffic patterns you are facing. For the consumer facing application, it's
not uncommon to see peak traffic 30-100 times over the averages at least
with the applications I've been involved with and I would hate to to budget
all resources based on peak consumption only. On the other hand, if the
number of pages on the site is small and the site is evenly in use, then
sure, it'd make sense to never purge.

  Hi,

  I summarized my results in following pdf file:
  http://www.schmelzer.cc/Downloads/Files/Tapestry-Memory-Performance.pdf
 
  The main issue is, that you are able to bring a Tapestry based system
 into
  a situation where it gets slower and slower and finally event not
  responding any more, just be decreasing memory on the JVM and you DO NOT
  get any error message or OutOfMemory warning or GC overhead warning.  And
  that only because the PageImpl instances are held in SoftReferences. My
  opinion is still, that this does not work as it is supposed to do and I
  keep with my example about other infrastructure. You would not expect
 e.g.
  Spring beans or a hibernate configuration to get thrown away under memory
  preasure - you would expect them to fail with OutOfMemory if they are not
  able to hold their necassary static information in memory.

It's generally not a good idea but it's possible. You need to watch for
memory consumption. Adding an already attached object to the session can
have adverse effects on memory consumption. Typically, you want to detach
the object from the first session and reattach the object to the second
session. I've written about the subject at

Yes, that's certainly an option and that's how I've approached the

you typically already have an http server to deploy the Ember bits to. And
if you have to figure out packaging into a .war anyway, then might make

@Ivano - if popularity was a measure, we'd all be still using Struts
instead of Tapestry, wouldn't we? Convention over configuration is one
thing, but the article you linked to is a fairly well balanced in my

 Hi, I am quite new to Tapestry, but last month I am upgrading our app from
 Tapestry 5.0.14 to 5.3.8. It's working now with one problem.
 We use Tomcat 7, servlet 3.0 (in the future Tomcat 8 and servlet 3.1) and
 Java 7. Tomcat listens on http (8080) and https(8443). If I use https,
 everything is OK.
 If I use http, I enter login page off app and SessionState object is
 created. I can see Session ID (equals X). It's done
 by contributeApplicationStateManager function in Module. Another contribute
 is for URL (contributeServiceOverride) where we use only https connection.
 That's because we want all ajax requests to go over https even if user is
 on http.
 So if user log in, session and cookie is created with atribute httpOnly and
 if I send ajax request to https, another session is created by Tapestry.
 Is it possible to access the http session in https request?


In general, no, it's not possible. This is a security issue and it's not
related to Tapestry. Container-specific configuration may allow
joining/sharing sessions on the servers (I recall having done something
similar in the past with Tomcat). I'd advise simply using https everywhere,
it'll make your life easier.

Re: SoftReferences to PageImpl can cause performance problems

 I do not agree with you on that  point. Tapestry is designed to cache the
 page. When you do not have enough memory to hold your pages cached
 basically the system does not work as designed so you should fail early.
 Otherwise you possible defer the problem to production use. Fail early
 means you should try to see the problem in the early stages on dev, where
 you try out all your pages. As I mentioned in my other post - you would
 also not expect the EntityManager to work soft-refereences or spring
 application context to work soft referenced.


That's the definition of a memory cache - it trades memory for better
performance. The primary use case for soft refences is for caching so seems
to me it works exactly as designed. Your comparison to the EntityManager is
flawed since it's created per request. An EntityManager is designed to be
inexpensive to create. There are many areas that need improvements in
Tapestry but this is not one in my opinion. However, you seem to strongly
think otherwise, so you probably have some data to back this up. Do you
have a memory dump and trending cpu/memory charts of a sufficiently large
system you can share with us to demonstrate the problem? Jvisualvm
snapshots should work fine. And furthermore - how would you like this
changed? If it's just adding a Page as a threadlocal, perhaps you can just
write a patch for it.

You are right George. Ever since the loopback reset listeners was put it in
(for T5.3), the LinkSource.createPageRenderLink(...) doesn't anymore work
outside request context (e.g. in a scheduled job). You should instead use
the linkEncoder directly (as in the implementation for
createPageRenderLink):

PageRenderRequestParameters parameters = new
PageRenderRequestParameters(canonical, new ArrayEventContext(
typeCoercer, context), loopback);
Link link = linkEncoder.createPageRenderLink(parameters);

Set loopback to false, you don't need it.

Somebody's gotta be the first one. I guess many of the existing

  PageRenderRequestParameters parameters = new

 One last thing before we move on from this issue, what is the

 context is just my url context values?


Take another look at the source you pointed to yourself, but: String
canonical = resolver.canonicalizePageName(pageName);

Re: HibernateEntityValueEncoder NullPointerException - Composite/Compund Primary Key Issue

[Kalle Korhonen]

I see Lance already answered to your question on Stackoverflow. Follow his
advice and make sure you contribute the encoder. After that, you may hit
another issues with tynamo not recognizing @IdClass (see an old issue
https://jira.codehaus.org/browse/TYNAMO-168), whether it matters to you,
I'm not sure. I've used IdClasses before but not extensively, and don't
recall whether I've had them on tynamo-model or if I've simply ignored them
from it. As both Thiago and Lance mentioned, it's best to avoid composite
keys with Hibernate but I'm pretty sure you can get it to work if you need
to. I'm always happy to apply patches and please open an issue on github (
https://github.com/tynamo/tapestry-model) if you hit a specific issue with
tynamo-model (you may but you are not there yet :P ).

 Hi Tapestry Users,

 I'm using a CRUD framework called Tynamo, which in turn relies on Apache
 Tapestry and Hibernate. This all works fine, except for when I try to use
 it for CRUD on a table with a composite/compound primary key.
 I've decided not to go the @EmbeddedId route, since it seems to not work
 at all with the framework. That being said, I have been using the @IdClass
 method, which is mostly working; I think I'm a line or two of code away
 from success.
 The issue is that when it starts using reflection to build the objects, it
 blows up and says,
 org.apache.tapestry5.ioc.internal.util.TapestryException, caused by
 java.lang.NullPointerException at
 org.apache.tapestry5.internal.hibernate.HibernateEntityValueEncoder.init(HibernateEntityValueEncoder.java:51).
 I honestly have no idea what's the deal here, but since I have normal
 table CRUD operation working for numerous other tables, I would assume this
 is somehow related to this table using a composite/compound primary key.
 One thing I did try was to move the static inner class to its own package
 and remove the staticclass modifier, but the exact same error occurred.
 You can see my class below:

Re: Two fundamental questions.

Always worth mentioning tapestry-model (

you generalize your T5 CRUD implementation, the more it will start looking
like tapestry-model.

Naturally, you don't have a request to work with when you are executing
from a cron job. But if you just want to generate links, you don't need to
and you shouldn't use the request values. Contribute HOSTNAME, HOSTPORT and
HOSTPORT_SECURE and you can generate absolute urls without resorting to
reading the values from the request.

  Not really a problem. See http://www.sitemaps.org/protocol.html, section
 Using Sitemap index files (to group multiple sitemap files).

 Is there a way to get around the permission issue and write the file
 to webapp or will I be required to have to figure out an alternate
 approach as you suggested?

  Just write to the right folder. You were trying to write to the
 filesystem root, which wouldn't even work to get the sitemap web-accessible
 even if there was no permission problem. Make your code write the file to
 your expanded WAR root folder in Tomcat or other servlet container. This
 link, http://www.avajava.com/tutorials/lessons/how-do-i-
 get-the-location-of-my-web-application-context-in-the-file-system.html,
 should help you find the right folder.


In general, that's a bad advice. Containers are not required to expand the
WAR file at all and your files would be destroyed every time you deploy
them. I think the general accepted best practice is to pass a writable
directory root as an argument to your web application and write the files
there, for example /var/myapp/data. With T5, I usually supply the path
using symbol, in development environments pointing to build root and
explicitly set to an absolute path in production mode.

Tapestry-routing (http://tynamo.org/tapestry-routing+guide) explicitly

Re: view http response

You could easily write a Tapestry or even a standard servlet filter to

Re: Tynamo Tapestry-Security - Multiple Realms - How to Change Authentication Strategy

[Kalle Korhonen]

On Sun, Dec 21, 2014 at 8:55 AM, Charles Karow char...@karow.com wrote:

 I'm using Tynamo Tapestry-Security 0.6.0 with Tapestry 5.4, and finding it
 a very useful tool!!
 I am implementing two realms for two different classes of users that are
 stored in different tables in the database; both will use username/password
 authentication, and thus the same authentication token type. They are
 mutually exclusive - any given user will be found in one realm and not
 found in the other, so I will always have one realm that fails to
 authenticate.
 I see that in Tynamo the default authentication strategy has been replaced
 with a custom FirstExceptionStrategy, which improves the exception
 handling, but will only work if there is only one Realm per Token type.
 (See http://jira.codehaus.org/browse/TYNAMO-154) While I appreciate and
 value the ability to get the original exceptions, right now it seems more
 important to me to be able to have the two realms.
 So it seems to me that I should change the authentication strategy to one
 of Shiro's (e.g. First Successful or At Least One Successful), or
 eventually create my own custom strategy that would give me the best of
 both worlds, by passing on the correct exceptions, while allowing multiple
 realms using the same token type.


If you know the type of the user at login time (for example, your users
have different entry points or they pick a specific domain), it'd be far
easier to create separate tokens for each realm. The type of the token
tells the realm whether it should participate in the authentication of that
token, so if you use the same token for both realms, it'll always try and
fail one.


 I have tried to change the authentication strategy in my AppModule with
 the following code in addRealms():

 SecurityManager sm = SecurityUtils.getSecurityManager();
 DefaultWebSecurityManager wsm = (DefaultWebSecurityManager)sm;  //
  Class cast fails
 ModularRealmAuthenticator mra = (ModularRealmAuthenticator)
 wsm.getAuthenticator();
 mra.setAuthenticationStrategy(new FirstSuccessfulStrategy());

 It fails because the returned SecurityManager is actually the IOC
 ServiceProxy and not the SecurityManager object. I tried similar code in
 the Realm's constructor, with a similar failure.


Yeah, I've never liked that part of Shiro's native api myself (that in
multiple places you are required to downcast to specific types to reveal
more functionality). However, I've tried to publish enough of the security
api as services, so you don't have to navigate through Shiro's object tree
(native Shiro doesn't have such luxuries as an IoC container). In this case
as well, ModularRealmAuthenticator is a service, so you can just obtain it
directly and set a different authentication strategy. See the source for
SecurityModule to find out what exactly is published as a service (
https://github.com/tynamo/tapestry-security/blob/master/src/main/java/org/tynamo/security/services/SecurityModule.java
).

   If
additional servers cost you, but you can do dynamic horizontal

cpu/memory thresholds to spawn new instances, then sticky sessions
 are
actually desirable.

works if the components don't require an explicit persistence

Re: URL Rewriting to base

[Kalle Korhonen]

Hi George,

is there a convincing reason to use the same page for these two URLs? To
get the same end result with tapestry-routing (
http://tynamo.org/tapestry-routing+guide), I'd create two pages and
annotate them like so:

@At(/{0})
public class Profile {...}

@At(/{0}/{1})
public class AboutProfile {...}

 I ended up getting it working over the weekend, but boy does it seem like a
 hack. I used some of your work to help me get going such as SimpleLink,
 however I needed the parameters so I needed to complete the class.

 I'll look into a second level cache as that seems to be a better solution
 than what I came up with, for the time being if a page contained a package
 or existed in the root, I just ignored it and skipped the query.

 Where I found things to get very tricky was with the request parameters and
 additional pages. Example

 Original
 domain.com/profile/profiledomain?make=ford
 domain.com/profile/about-us/profiledomain

 profiledomain being the dynamic context

 Rewrite to
 domain/profiledomain?make=ford
 domain/profiledomain/about-us

 I ended up having to create some strange pagelinks where everything points
 back to profile.

 t:pagelink page=profile
 context=dealerProfile.profileDomainProfile/t:pagelink
 t:pagelink page=profile context=[dealerProfile.profileDomain,
 'about-us']About-Us/t:pagelink

 in the end it looks like this
 https://www.cardaddy.com/blue-marlin-motors
 https://www.cardaddy.com/blue-marlin-motors/about-us

 I'll post the rewrite rule later tonight, if you have a moment I'd like
 you take a look to be sure I don't end up shooting myself in the foot long
 term.

 Thiago as always, thank you very much.

  It's not a bad way actually, specially if you use some kind of cache on
  the query results. You can configure Hibernate to use a second-level
 cache.
  In addition, Tapestry 5.4's tapestry-ioc-jcache + some JCache
  implementation can help you with that in T-IoC level.
 
   So other than ignoring every package and page, how else could I
  dynamically do this?
 
 
  I'm not sure how else you can do that.

Update the version of the offending library, but perhaps not that easy.
Googling the exception gives you these potential matches:

 This is a Guava dependency version mismatch, not directly related to
 Tapestry. If you're using Maven, use dependency:tree or the Eclipse pom.xml
 editor to know what's happening.

Re: GAE 5.4-beta22 - access denied for modifyThreadGroup

[Kalle Korhonen]

GAE doesn't like user code calling ThreadGroup.getParent() (line 597 of
TapestryInternalUtils, in your stack trace) which seems an unnecessary
restriction given that access to Thread.currentThread().getThreadGroup() is
allowed. I wouldn't be surprised if there was a bug open against GAE on
that.

Anyway, you can certainly get it to work on GAE as well. The simple answer
is that you probably don't want to show the development exception page on
production anyway. Beyond that, you might need to override
ExceptionReport.getThreads() to return perhaps just the current thread. I
don't think the default behavior of Tapestry should change just for GAE.

 Bummer, I just confirmed that the same error happens when deployed in
 AppEngine. At first glance this looked similar to an issue that was fixed a
 couple of years ago (https://issues.apache.org/jira/browse/TAP5-1616), but
 this is definitely different. I do recall that in general in production one
 might want to have a different exception page (than this default), yet I
 wonder if there is anything that can still be done about this before 5.4
 goes out (if it's considered important enough for a 5.4 release).

  In the local environment, I can certainly start the local dev server
 with a jvmFlag-Denable_all_permissions=true/jvmFlag option that avoids
 the issue in my local setup, so it's not a massive deal. Yet, this was
 certainly not happening in 5.3.7 so I wonder what changed.
 
 
  Other than that, 5.4 just looks fantastic - I had been holding off on
 trying it out , but now I can't wait this release to go out !

  Check the Minimizing Assets section at the bottom of

 Hi all,

 I'm pleased to announce the release of arras-components and arras-cms.

 https://github.com/fscheffer/arras/

 *Arras-components* is set of components for Tapestry 5.4 (based on beta
 22).
 Currently the following components are part of the project:
 TabGroup, Dropdown, Lightbox, DataTable, Icon (fontawesome), RemoteSubmit,
 MediumEditor and Player (video and audio).

 Hopefully this list will grow further in the future.

 *Arras-cms* provides simple functionality to change the content of your
 site without actually having to redeploy it. It's using a WYSIWYG approach
 to change the content and is using tapestry-jpa to read and write content
 from and to a database.

 The jar files for both, arras-components and arras-cms, are available on
 Maven Central.

 If there are any questions or suggestions or feedback, feel free to contact
 me.
