Hi!
I'm currently using Struts, but am considering wether
to use WebWork2 for a new project - having read
positive things about it.
To vent this first:
I actually spent several -hours- searching through
different homepages, documentation fragments and
mailing lists and cvs repositories before finally
getting my hands on working example application. If
I'd been just a little less stubborn I would have
decided to ditch WebWork2 once and for all, and settle
with "good old Struts". At least with Struts there is
an acceptable level of new-user friendliness, with one
defined homepage, coherent documentation and downloads
that actually work. The only webwork2 examplewar
publicly available does not work. I eventually had to
register with java.net and wait until the next day for
approval, then check out the whole project source from
cvs, and then build the webwork-example.war myself. If
you guys try to build your own Ivory Tower, you're
succeeding very well - it surely is not a very good
way to encurage newbies.
Phew - now that I've got that out of my system... :-)
Now for the example web application:
This (I suppose) will be the first contact a new user
has with the framework. Therefore it should work. And
it should demonstrate some essential features of the
framework. And I should not be forced to read the
comments in the source code to understand what is
going on. The example should be simple and self
explanatory.
I think I read somewhere in the documentation or
mailing list that the only thing remaining before
removing the "beta" is that you're waiting for a new
release of OGNL. Right? Unless you're planning on a
few rounds with RC before releasing, I would suggest
fixing up the example application a bit more first. If
you really want to challenge Struts as the prefered
framework you need too convert former Struts users,
and to effectively doing that you need a more
newbie-friendly entrypoint (examples+documentation).
These are my comments after going through
webwork-example.war. As mentioned I had to build it
myself from cvs, using "ant example-war". These
comments are only ment to help you polish the
examples, so dumb-ass newbies like myself don't decide
to run home to Struts... :-)
Starting example webapp, Tomcat log shows :
SEVERE: Could not find test.properties. Skipping
02.nov.2003 13:45:33
com.opensymphony.webwork.config.DefaultConfiguration
<init>
SEVERE: Could not find
com/opensymphony/webwork/othertest.properties.
Skipping
02.nov.2003 13:45:33
com.opensymphony.webwork.views.velocity.VelocityManager
loadConfiguration
Example webapp :
Click here for a stupid little counter
Getting this exception:
org.apache.jasper.JasperException: Unable to find
value for name VelocityCounter
Click here for an example of the Form Tag and the
Token Tag for hidden transaction tokens
Result looks exactly the same wether I use the form
with token or no token.
Is the HTML source supposed to be like this (with $)?
:
<input type="hidden" name="webwork.token.name"
value="$parameters.name"/>
<input type="hidden" name="$parameters.name"
value="HLA8C0Q8RK3HYQQGQO4I4PC5CRZMI0SL"/><br>
Click here for a basic validation example
I was expecting some kind of validation messages when
I entered illegal data.
But no matter what I type (legal/illegal), the form
just seems to be reset when I submit..?
Click here for a visitor validation example
Same as basic validation. In addition Tomcat log shows
exception on first run (not on subsequent) :
INFO: Starting execution stack for action
visitorValidation
java.text.ParseException: Unparseable date:
"01/01/1970"
at
java.text.DateFormat.parse(DateFormat.java:334)
Click here for a visitor validation example with
expression validation
Same as basic validation.
Click here to view the FormTag example using a
location resolved via ognl
Result looks exactly the same wether I use the form
with token or no token.
Is it supposed to be this way?
Any comments appreciated.
I believe the WebWork2 developers are doing a great
job. But I think you need someone to boost up the
documentation side of the product, in order to gain
more users.
Regards. :-)
