[JBoss-user] [O'Reilly JBoss 3.0/4.0 Workbook] - rmh - enterprise javabeans, 4th ed. exercise 15.1 doesn't wo
recently, i bought enterprise javabeans, 4th ed by richard
monson-haefel, bill burke and sacha labourey.
i have installations of jboss 3.2.3 (java 1.4.1) on my gentoo
linux server and jboss 4.0.0 rc2 (java 1.5.0-rc-b63) on windows
xp sp2 on my tabletpc/localhost. i strongly prefer to use the
jboss4 server as this is a) the future and b) i do prototyping
only (stability isn't an issue for me right now).
on jboss4/localhost i checked out most of the examples in the
jboss workbook included with rmh-ejb. however, the one i needed
most, exercise 15.1: web services and ejb 2.1 doesn't seem to
work on my local jboss4 server. first it failed to build,
probably due to deprecated/missing jboss.net support in jboss4.
so i tried to replace
fileset dir=${jboss.home}/server/default/deploy/jboss-net.sar
|
with
fileset dir=${jboss.home}/server/default/deploy/jboss-ws4ee.sar
on line 15 in ex15_1\build.xml
using this, ant didn't complain when building the server-side of
the example ('ant wsdl', 'ant ejbjar'). however, when restarting
jboss4, the server log reads:
12:00:09,420 INFO [EJBDeployer] Deployed:
| file:/C:/jboss-4.0.0RC2/server/defaul
| t/deploy/titan.jar
| 12:00:09,621 ERROR [ServiceDeployer] Cannot startup webservice
| for: titan.jar
| java.lang.IllegalArgumentException: The wsdl file should be
| located in: META-INF
| /wsdl/
etc.
my questions:
*
q1:
***
how can i make this example work (nicely) with jboss4? if the
example, as downloaded from
http://examples.oreilly.com/entjbeans4/workbook.zip, doesn't work
with jboss4 indeed, i'd kindly ask to release an update of it as
quickly as possible. jboss4 is suggested in the workbook and i
believe most people prefer a web service example using
jboss-ws4ee (j2ee 1.4 compliant) instead of jboss-net (the axis
way, deprecated).
q2:
***
apart from the problem described above, running the client of
exercise 15.1 threw some exceptions. do you have any idea what's
wrong here and how i can make it work in my environment (jboss4,
java 1.5.0-rc-b63, windows xp sp2)?
the following steps worked fine:
'ant clean.db'
| 'ant createdb'
|
the following threw exceptions:
C:\unison_sync\thesis\working\current\code\examples\oreilly\workbook\ex15_1MakeReservation

any help appreciated, regards

p.s. it can be safely assumed that line wrappings are correct,
despite of wrong appearance above.

[JBoss-user] [Beginners Corner] - presentation level integration using jboss: how? (web servic
(view using mono-space font for proper ascii-art display ;)
i'd like to write a presentation level integration prototype using jboss (4.0, if
possible). therefore, the presentation layer (to be implemented) needs to provide the
following different services to a client (browser and/or rich client):
* a soap interface (i.e. the client must be able to access a web service using soap.
the web service should be provided):
client soap presentation layer (server-side)
* apart from providing a soap interface, the presentation layer (pl) should also be
able to transform xml-data into various other xml formats (xhtml, xul, wml, ..) using
a server-side xslt transformation:
client http presentation layer (server-side)
|
| {xhtml, xul {xml} transformation using xslt
| wml, ..}
constraints:
* the whole thing should be *as simple as possible* as it only serves as a
*demonstration prototype*.
* the other layers (business logic tier, data tier) of this n-tier architecture don't
matter for the prototype (of course they matter for presenation level integration, but
this prototype is supposed to show only few aspects of presentation level
integration). whatever is the simplest to understand and implement.
* the presentation layer should preferably use session beans mainly (eventually an
entity bean to hold the xml data)
* as a design pattern for the presentation layer i'm thinking about using a
model-view-controller (mvc) pattern or a business delegate pattern (see: matjaz b.
juric professional j2ee eai)
questions:
**
* how can i implement an xml to xyz transformation using xslt in jboss? (i.e. how can
i apply a xslt sheet on xml using jboss? is this done using a servlet? how?)
* how should i combine/couple the soap interface component(s) and the xml/xslt
transformation component(s)?
* is there any example code showing this or aspects/parts of it?
* am i totally wrong in choosing jboss for this purpose? would another
technology/product (e.g. axis, tomcat or a java mvc framework like
http://www.springframework.org/) be better suitable to implement a presentation level
integration prototype?
* any suggestions or recommendations on the topic (presentation level integration)
or my intentions as explained? i.e. do you have any better ideas to showcase
presentation level integration using jboss (or an alternative product/technology)?
any hint/tip/recommendation is welcome!
regards
dani
