hi.
I'm trying to catch various exceptions that can be launched from any =
component so I have that in the xml controller file:
....
<on-exception class=3D'org.actionframework.ActionException' =
show-url=3D'url'>
<output-variable name=3D'url' value=3D'$SERVLET/' />
</on-exception>
<on-exception =
class=3D'com.hola.postales.exceptions.InvalidPostcardException' =
show-url=3D'url'>
<output-variable name=3D'url' value=3D'$SERVLET/' />
</on-exception> =20
=20
</components>
</application>
but I become the following error:
Wrong order of <on-exception> classes: =
'org.actionframework.ActionException' cannot follow =
'org.actionframework.ActionException'
If I have only one <on-exception> it's catched whenever it's neccesary, =
but when there are more than one, it doesn't work.
thx in advance.

Hello! I am wondering if there is some progress in AS development. What are the plans? I haven't seen an update/list traffic for a long time. I am using current version in my project. It would be nice to have some more things from the roadmap document implemented. Best regards Jakub Cerny |

There seems to be a bug in ActionRuntime.parseUrlParams(). Replace
line 1307 (AS 0.94.2):
newAction.append("/.+");
with
newAction.append("/[^/]+");
and rebuild lib/ActionServlet.jar by running "ant" from AS directory.

Example: 1. <action name="/entrada/" method="getRandomQuiz()"> 2. <action name="/entrada/$section" method="getRandomQuiz(String section)"> 3. <action name="/entrada/$section/$name" method="getQuiz(String section, String name)"> When you have "123 order" written all is right. But with "312 order" if you ask for '/entrada/section/name', ActionServlet invoke the second method as "/entrada/$section" action. Hope it'll be useful. Regards, Raul Perez |

Hello AS users! I have a question/feature request. If there is a Exception generated in my business logic, it is usually caught by AS and the <on-exception> directive is used. Sometimes there is an exception generated in view layer (Velocity) and I see the stack trace being flushed somewhere in the middle of output, which looks bad. Is there some possibility to also catch these view-related exceptions? Of course it is somehow possible to force Velocity to be silent, but some kind of support from the framework would be nice. I noticed similar issue was once mentioned on this list, but I am not sure if some solution has been proposed. Thanks in advance for all comments/hints. Best regards Jakub Cerny, Prague BTW I noticed some progress in roadmap document, is there some new release planned? |

ActionServlet 0.94.2 (http://www.actionframework.org) Changes from 0.94.1 to 0.94.2 ----------------------------- - Velocity 1.3+ is required to rebuild ActionServlet sources - application attribute named "javax.servlet.ServletContex" is set on servlet startup for Velocity 1.3+ - relative and absolute paths can be now used together with Velocity for 'file.resource.loader.path' and 'runtime.log' Velocity properties - absolute paths must start with slash ('/') or have Windows format ('C:\...'); this is a small incompatibility with previous releases! - retrieval of type handlers is now faster thanks to caching - bugfix: ActionConfig could not be loaded from unexpanded .war file - changes in examples: - removed leading slash from relative template paths in Velocity.properties Thanks everyone for comments and patches! -Petr PS: AS 0.95beta still in (slow, but certain) progress... -- [ http://dione.zcu.cz/~toman40 - Pet...@pi... - ICQ=22957959 ] |

Good idea. Maybe adding some attribute to <post-invoke> would be
a "softer" solution instead of introducing a new element.

Yes, JNDI will be a standard way to achieve this. At present, you=20
can create a class with static accessors. A simple example:
public class MyServlet extends ActionServlet {
private static MyServlet _self;
public MyServlet() {
if (_self !=3D null)
throw new IllegalStateException("There seems to be " +
"a problem with the servlet container's class loader");
_self =3D this;
}
public static Object getASComponent(...)=20
throws InstantiatorException {
if (_self =3D=3D null)
throw new IllegalStateException("ActionServlet was " +
"not yet initialized");
return _self.getComponent(...);
}
}

Jetty supports running webapps from wars without expanding them and I wou=
ld like to do this with ActionServlet. The problem is that as the war is =
not expanded
there is no filesystem for the webapp so all templates and property files=
have to be loaded as resources or via the classpath.
I have had to patch two files in ActionServlet to support running from un=
expanded wars. These are used to load the velocity properties and action =
config files.
Details below:
1) org.actionframework.engines.velocity.VelocityServlet
If loading the velocity properties file by the real path fails then we tr=
y loading as a resource. (The diff below also contains the change for abs=
olute log file paths

This is also good idea, but I have my actions bound to methods of 'session'
scoped component so I would have to create that special component from
inside other component via as.getComponent() - which seem little dirty to
me.
I would really suggest to have something like <post-render-invoke> in some
future release.
----------------------------------------------------------------------------
---------------------------------
<dreaming>
One more question/suggestion: It would be really nice to have some way of
accessing AS components from any class. I know that JNDI is planned, that
would be great! I was thinking about some class with static AS component
accessors, but I didn't succeed.
Imagine this:
You have AS component "PersistenceManager" with session scope. This
component has all the DB specific stuff in it.
Then you create your datamodel classes according to ActiveRecord pattern, so
you have methods like
person.persist()
person.delete() etc.
And you can implement these methods (in common BaseClass!) like:
void persist() {
pm = somehowGetASComponent("PersistenceManager");
pm.save(this);
}
It seems to me that now the only way is to pass AS to all classes in
constructor which looks quite ugly...
</dreaming>
Many greetings to you all!

Petr, all, For deployment purposes, we need to access Velocity templates from outside the servlet context. We have patched method 'relativizeLoaderPath' in org.actionframework.engines.velocity.VelocityServlet as follows: 74c74,76 < String realPath = getServletContext().getRealPath(token); --- > String realPath = (token.charAt(0)=='/') > ? token > : getServletContext().getRealPath(token); It will leave unchanged the absolute paths in velocity.properties. I hope you find it acceptable for next revision. Best regards, Armando -- Armando Ramos http://www.hola.com |

Hello AS users! In my project I am using O/R mapping tool (Hibernate). I am trying to use "long sessions" which means I keep the Hibernate session stored inside AS component with 'session' persistence. This is working fine but I want to disconnect from DB after each request and reconnect before the next one (for better scalability). So I created: <pre-invoke>connect to DB</pre-invoke> and <post-invoke>disconnect from DB</post-invoke> This is OK but the problem is, that connection is closed BEFORE the view is rendered. Hibernate uses so-called LAZY INIT, which means, that id doesn't load whole object hierarchy at once, but lazily when children objects are needed. And this exactly happens here. I call loadFamily() in action method and the template then uses $family.getKids() etc.... But these calls need the DB connection to be alive. So I am asking. Is there an elegant solution to call method after the view is rendered? I know that <template> can include <invoke> but this is called before rendering. Thanks in advance for your ideas. Greetings Jakub Cerny |
