[Actionframework-users] ANNOUNCE: ActionPack 05-Jul-2002

[Petr T. <Pet...@pi...>]

* ActionPack *
(http://dione.zcu.cz/~toman40/ActionPack)

- upgraded modules:
   - ActionServlet 0.93.1 -> 0.93.1a
   - ASWizards 1.23 -> 1.23a
   - AS_miniRMI_Connector 0.92 -> 0.92a
   - JASSModule 0.51 -> 0.51.1
   - miniRMI 0.94.1 -> 0.94.2
   - Webrunner 0.5 -> 0.5a
- lib\webmacro.jar upgraded 1.0 -> 1.0.1
- licenses of ASWizards and WebRunner changed from GNU GPL to GNU LGPL
   (because of "plug-in issue")
- setup now skips modules rebuilding -> much faster installation


* ActionServlet *
- session based initialization code is now run before
   ActionServlet.handle() is called - this allows calling getComponent()
   method from handle()
- bugfix: templates names caching removed (caused 'template was not
   loaded by getTemplate() method' error when template name cache expired
- bugfix: JavaBeansInstantiator didn't initialize props of re-created
   component
- bugfix: URLParameterRetriever didn't retrieve last single-character
   parameter

* JAASModule *
- bugfix: StaticPermissionsDefs.getPermissionTargetActions() method
           caused NullPointerException for undefined permission 'target'

* miniRMI *
- fixed miniRMIC support for JBuilder 7 (JBuilder OpenTools API has
   changed)

You can override beforeConversion() method in servlet, put actionName to 
Context and in the type handler convert according to the action.

I've been thinking of an enhancement of ActionConfig, that would allow 
more granularity for selecting type handlers - like:

<action name="/actionA" method="methodA(java.util.ArrayList listA)">
    <input-variable name="listA" value="roleUids[]">
       <type-handler class="org.visres.ivr.security.HandlerA"/>
    </input-variable>
    <on-return value="void" show-template="xxxx"/>
</action>

I hope to find some time for AS this week.

[Actionframework-users] Type Handlers...

[Mandip S. S. <ma...@su...>]

Hi Petr

Thanks for the quick response on the regex problem (the trailing slash 
solution worked a treat :-) ).

I am currently using type handlers and have an issue which I need 
suggestions on.  I have two type handlers which have the same 
source-type and target-type i.e.

<type-handlers>
    <type-handler target-type="java.util.ArrayList" 
class="org.visres.ivr.security.HandlerA"/>
    <type-handler target-type="java.util.ArrayList" 
class="org.visres.ivr.security.HandlerB"/>
</type-handlers>

The problem is how do I make different methods in different actions 
specifiy which type-handler to use when the method parameter type is the 
same (in this case the paramter type being a java.util.ArrayList) i.e.

<action name="/actionA" method="methodA(java.util.ArrayList listA)">
    <input-variable name="listA" value="roleUids[]"/>
    <on-return value="void" show-template="xxxx"/>
 </action>

Needs to use HandlerA and

<action name="/actionB" method="methodB(java.util.ArrayList listB)">
    <input-variable name="listB" value="roleUids[]"/>
    <on-return value="void" show-template="xxxx"/>
 </action>

needs to use HandlerB.

At the moment I can have however many type handlers with the same 
source-type and target-type but all methods that have a 
java.util.ArrayList as a parameter will all use the same type handler.

Any suggestions would be much appreciated.

Mandip

You have discovered a bug in URLParameterRetriever [line 60], which shoul=
d
be:

    if (start =3D=3D -1) return null;

You can also add trailing slash to your URL:

http://localhost:8081/ActionServlet/editUser/a/

Both should work,

[Actionframework-users] Regex Action problem...

[Mandip S. S. <ma...@su...>]

Hi All

I'm trying to use a regex action i.e.

<action name="/editUser/$userUid" method="getUser(String userUid)">
    <on-return value="*" assign-to="user" 
show-template="org/visres/ivr/security/EditUser.html.vm"/>
</action>

However when I have a url that only has one character after the action 
the resulting userUid always gets passed as null i.e.

http://localhost:8081/ActionServlet/editUser/0
OR
http://localhost:8081/ActionServlet/editUser/a

All pass user userUid as null.


However anything with more than one character gets passed okay i.e.

http://localhost:8081/ActionServlet/editUser/00
OR
http://localhost:8081/ActionServlet/editUser/aa

Any suggestions would be much appreciated.

Regards
Mandip

You need to escape '&' ('<','>','"' etc.) in XML - like you should in 
HTML, i.e.: if="cond1 &amp;&amp; cond2"

'<' is escaped as &lt;
'>' as &gt;
'"' as &quot;
'&' as &amp;

Petr,

Great, I will checkout and look at it.

Just a few comments on some items

> [ ] add ActionServlet.destroyComponent(String componentName) method

Good idea, we have a funny situation. When we shut down jetty it is not 
shutting down all of the application. Some threads continue to run. Is 
this the velocity servlet or something else?

Just checking, will I be able to use pre-condition to handle GET and 
POST separately. My preferred option is a separate action but if 
pre-condition will allow me to choose the action depending on GET/POST 
and HTTP/HTTP then that is OK.

Ooh good.

Fine

Thanks for all this.

[Actionframework-users] Proposals for 0.94

[Petr T. <Pet...@pi...>]

Hello,
I have made the cvs working finally. I hope SF guys make the domain WWW
(vhost) respond correctly soon.

Here's a todo for AS 0.94:

[ ] enable passing of all HTTP parameters (= put everything to Context)
[ ] add ActionServlet.destroyComponent(String componentName) method
[ ] add ActionServlet.getTypeHandler(...) method
[ ] add BaseCompositeHandler + javadoc org.actionframework.th package
[ ] allow <on-exception>s common to all components
[ ] add new <on-new-session> element - allowing 'show-url' redirect
     (ensure $SERVLET, $URL and $REQUEST are set before processing it!)
[ ] should newSession() return Object instead of Template?
[ ] implement <pre-condition>s - example:

     <pre-condition if="$var" show-template="loggedIn.wm">
        <input-variable name="var" component="auth"
                        value="isLoggedIn()"/>
     </pre-condition>
     <pre-condition if="!$REQUEST.isSecure()" show-url="https://...">

     <pre-condition>s may be defined for:
     - all components (inside <components>)
     - all action of one component (inside <component>)
     - single action (inside <action>)

[ ] allow evaluation of 'show-url' directly, not only via
     <output-variable>
[ ] put $REQUEST (of type HttpServletRequest) to Context - like $SERVLET
[ ] enable <property> values like:

     <property name="SomeProperty" value="$xyz">
        <input-variable name="xyz" component="Comp" value="getValue()"/>
     </property>

[ ] enable <template> names containing regexps
[ ] allow invocation of static method of components in <in/out-var>s
[ ] examples configuration + out-of-box ant task for Jetty

I'm saving few other idas for later versions (postprocessing - XSL/VSL, 
ActionClient/ActionController architecture, enhancements to THs, better 
logging, writing more sophisticated tutorial etc.)

I don't think I will have much time in the following two weeks, but I'm 
going to commit two small bugfixes soon (JavaBeansInstantiator and 
expiration of templates relict).

Comments are welcome (as always :))

How about $context :)

Personally, I would like to wait with this until ActionClient version
(AS technology used on client side planned for 0.95/0.96), because this
can be done in beforeInvoke() as you have noted.

Of course, we can discuss what else may be put there.

There is no API for getting info from ActionConfig (I plan this for 
future releases, when ActionConfig is "stable" enough). Currently you 
need to parse the XML by yourself - getting components and their actions 
is quite easy - you can take the code from ActionRuntime.init().

PS: I have problems with ssh, so I'm sorry that cvs is not set up yet.

[Actionframework-users] Automatic Menu

[David W. <da...@su...>]

Hi,

I wrote the other day about automatically populating the context with 
some values, eg the Action.

Now I want to be able to access more things about ActionServlet from the 
context.

I want to build a menu of available actions automatically. If we 
organize the components and actions within them then I think I can use a 
list of components/actions as my menu (a combobox in the header of items 
to jump to). Obviously not all actions should be listed (I guess firstly 
only gets and not posts, maybe I will use a standard interface for all 
components that will allow me to check for valid actions for the menu or 
something).

Anyway the starting point is to make available to the context all 
components and actions. Does anyone know how to do that?

Thanks

Dave

[Actionframework-users] Default items into the Context

[David W. <da...@su...>]

At present $SERVLET and $URL are placed in the context

I need some others (Action is the first I need and yes I know I can add 
in my servlet beforeInvoke or handle methods) but it has made me think 
the following

We may want to add extra standard items to the context in future 
releases, but this risks namespace problems. So instead why don't we put 
an ActionFrameworkStandardContext object into the context. At the moment 
this would give us to use in our templates

$ActionFramework.Servlet
$ActionFramework.Url
$ActionFramework.Action
$ActionFramework.Version

But I can see lots of other good stuff that could go in here, some of it 
depending on the debug level of ActionFramework so that if debugging it 
makes extra diagnostics available, giving us a similar feature to 
phpinfo() which is great when installing/diagnosing php.

I don't mind if we use ActionServlet, ActionFramework, AS or AF as the 
name in the context.

What do you think?

Dave
