Caching of Seam Remoting Interface Components
by Ashish Tonse
All,
I am currently working on implementing Seam on part of a relatively high
traffic site (8k+ concurrent users) and optimizing our backend and frontend
to handle that traffic. When focusing on front-end, I'm trying to make sure
that the right HTTP caching headers are sent out -- but our Seam Remoting
javascript files can't be browser-cached for a couple of reasons:
/interface.js?componentName won't get cached due to it containing a query
string and the way browsers handle those
/remote.js always returns an HTTP 200 with the actual file contents,
whereas this file would only change with new Seam releases (is that
correct?)
Also, neither of these JS files are combined, packed or minified.
The Seam Remoting InterfaceGenerator does have an interface cache for each
component, so at least that time is saved. But it still sends back
unnecessary unchanged content to the browser. Since javascript downloads
block all other downloads in the browser, this is especially noticeable with
load times, making the page seem slower.
A good potential solution (suggested by Dan Allen on twitter) to the first
issue... use the ReWrite filter. My guess would be something like this:
/interface/componentName.js --> interface.js?componentName
And if we sent the right HTTP caching headers, that would fix that issue
and browsers could cache it. But what about using multiple components? This
is what I propose...
/interface/componentName1,componentName2,componentName3.js ----->
/interface.js?componentName1,componentName2,componentName3
these still are valid and "RESTful" URLs... and can be cached.
Is this something reasonable enough that I can take on as my first
Seam contribution? (Seems
small enough)...
Furthermore, in non-debug mode, Seam should send back minified Javascript
(using the Java based YUI-compressor)
Please let me know your thoughts before I get started,
Thanks,

Things to do after committing a change in an xml file of the reference manual?
by denis.forveille＠gmail.com
I've corrected a minor bug in the seam reference guide (JBSEAM-4256).
For this I updated and committed the file named
"doc/Seam_Reference_Guide/en-US/I18n.xml"
Q:
- do I have to do something extra (update/generate/commit/?) to cope
with the corresponding "I18n.po" files for the other locales?
- or is it the build (or someone/something else) that will
update/generate/commit those files?
Thx

Seam 2.2.0.CR1 testing results
by Ondřej Skutka
Hi!
I'm sending you results of the Seam 2.2.0.CR1 testing. We focused on JDK
1.6 / JBoss 5.1.0 GA as this is the platform that EAP 5 is based on.
We have found four critical/blocker issues (seam-gen, JBDS: JBSEAM-4265,
JBSEAM-4258, JBSEAM-4257, JBSEAM-4266) and thus I think that we should
go with a CR2 release and run all the tests again to ensure that the
resolved bugs don't break anything. Jozef will be back at work by
tomorrow, so the CR2 testing should be faster that the CR1.
Although I have closed JBSeam-4269 as a duplicate of JBSEAM-4266, I'm
not all that sure it's the same bug.
We haven't tested Portlet Bridge and Tomcat 6. We are going to test
tomcat 6 tomorrow.
Thanks Jozef for testing the seam-gen even though he was on PTO!

by Pete Muir
http://in.relation.to/Bloggers/Seam220CR1Released
Many thanks to Norman for managing the work on this release, Tiho and
Stuart for their major contributions, and Ondrej and Jozef for finding
lots of issues during testing.
We'll try to move quite quickly to GA, so let's get any issues that
people reported tracked and fixed quickly :-)

Re: Hibernate search 3.1.1.GA w/ seam
by Sanne Grinovero
I've been stepping through the blog example with a debugger to look
into JBSEAM-4257;
the transaction is fine but it appears that it doesn't get to commit
after the method invocation.
If I convert the component to a @Stateful bean *and* change the "@In
FullTextEntityManager" into
a "@PersistenceContext EntityManager" it does work: the transaction is
committed and the test
succeeds.
If I only convert the pojo into a Stateful bean and keep using "@In"
to inject entitymanager, it doesn't
inject and the method is called having null EntityManager -> NPE.
The dvdstore example is not affected by this, as the indexer
implementation of dvdstore
is using a @Stateful bean and @PersistenceContext already.
The problem is the @Create annotated method combined with @Startup and
@Scope(ScopeType.APPLICATION):
if I remove @Startup and have the method called before the first
search (I experimented having it injected with create=true in the
search
service) the behaviour is correct: the transaction is committed, the
index is updated and the search results are fine.
I've opened JBSEAM-4278 for this; should I open a second one for the
missing injections in EJB3 stateful beans?
I'm not sure if it the same issue, I mentioned it in the description.

Getting more out of annotation processors
by Gavin King
Folks, as we start work on Seam3, and the tooling for Seam3, we need
to look out for opportunities to get more out of annotation
processors. They can help us solve certain problems that we weren't
able to easily solve in the past.
One thing I would definitely like us to do is DAO generation. What I'm
thinking of is like a next generation version of the "framework"
package in Seam. For example, for each entity like Customer we could
generate a class CustomerHome extending EntityHome and adding typesafe
finder methods (findByName() and friends). Of course, the user could
extend and specialize this generated class to override or add extra
functionality.
It would even be possible to generate JSF composite components for
each entity, i.e. <e:displayCustomer/>, <e:editCustomer/>,
<e:displayCustomerAsRow/>.
Of course, all this would need to work nicely in Eclipse.

Deployment issues in JBoss-Embedded
by Marek Novotny
Hi,
first I know that JBoss Embedded is not supported, but anyway if
somebody can help me, I'd appreciate it very much.
I get the attached exception in seam integration testsuite. Sometimes it
is thrown without java.util.ConcurrentModificationException stacktrace.
What was changed in JBoss Embedded? I upgraded hibernate libs:
hibernate-core to 3.3.1.GA
hibernate-annotations to 3.4.0.GA
hibernate-commons-annotations to 3.1.0.GA
hibernate entitymanager to 3.4.0.GA
hibernate-validator to 3.1.0.GA
in test-build dir which is in classpath is the following
destinations-service configuration:
<server>
<mbean code="org.jboss.mq.server.jmx.Topic"
name="jboss.mq.destination:service=Topic,name=testTopic">
<depends optional-attribute-name="ServerPeer">
jboss.messaging:service=ServerPeer
</depends>
<depends>jboss.messaging:service=PostOffice</depends>
</mbean>
<mbean code="org.jboss.mq.server.jmx.Queue"
name="jboss.mq.destination:service=Queue,name=testQueue">
<depends optional-attribute-name="ServerPeer">
jboss.messaging:service=ServerPeer
</depends>
<depends>jboss.messaging:service=PostOffice</depends>
</mbean>
</server>
Thanks in advance,
