[S2] Issue with NamedVariablePatternMatcher and ActionConfigMatcher?

[cilquirm]

Hi all,

I've been spending time with Struts 2.1.6, and the
NamedVariablePatternMatcher, and I've come across a potential issue. 

The issue comes into play when defining a class such as this :

@Namespace("/content/{year}/{month}")
public class ContentAction extends ActionSupport {

  private Integer year = null, month = null;
  private String article =  null;

  public void setYear(Integer y) { this.year = y; }
  public Integer getYear() { return this.year; }

  public void setMonth(Integer m) { this.month = m; }
  public Integer getMonth() { return this.month; }

  public void setArticle(String a) { this.article = a: }
  public String getArticle() { return this.article; }

  @Action(value = "{article}", results = { @Result(name="success", location
= "/WEB-INF/content/content.jsp" ) } , params = { "article", "{article}" } )
  public String execute() {
 // do some db stuff
 return SUCCESS;
  }

}

In this case, I'm trying to "wildcard" map all my content into a single
action, and be able to get the name of the content being matched.. 

Hence, 
http://webserver.com/myapp/content/2009/01/some-piece-of-content.action
should result in :

year - 2009
month - 1
article = some-piece-of-content
 
The problem it seems, is that while the NamespaceMatcher defers to the
NamedVariablePatternMatcher to parse out and map to parameters in the
Namespace configuration, the ActionConfigMatcher still believes it's using a
simple wildcard matcher, as it calls AbstractMatcher's convertParam, which
only checks for variable names of length ( i assume this is because it's
only looking for parameter names 1 through 9 )

I have a temporary hack where I replace AbstractMatcher with my own slightly
modified version which does it's replacement much like how
NamedVariablePatternMatcher does it ( like a simplistic state-machine )

I would open up a ticket on this but I wanted to understand if i was
possibly doing something wrong, or if I had missed another angle at it, or
better still, if there was already thinking and work done behind this.

Thanks in advance for any help you might be able to provide,

I'm confused by this also.  I thought an example implied either a real-world
or contrived scenario where the problem in question manifests itself.

RE: Struts2 Cookbook Question

[cilquirm]

There's nothing preventing you from adding back commons-beanutils or OSCore (
http://www.opensymphony.com/oscore/ ) to get back to that level of
functionality.

I'm not 100% sure why this mechanism is necessary.  If you name your getter
on your TestBean appropriately, S2 should take care of it.

RE: ModelDriven CRUD validation failure still causes JPA update - RESOLVED

[cilquirm]

You can throw an exception , which you can specify in your 

@Transactional( rollbackFor = )

to have it rollback.

Re: [Struts 2] : Zero Configuraiton : some feedback

[cilquirm]

I use Zero Conf and codebehind a lot, and I think they're both incredibly
useful.  especially in this newer world of convention over configuration,
etc...  When I have a package hierarchy all set up, i don't feel the need to
muck with struts.xml, because I can get directly down to coding. 

There are cases where you have to go back to struts.xml ( like wildcarding,
and being able to customize and manage interceptor refs ) , and that needs
some looking into.  

In my opinion, ZeroConf and Codebehind need to be together, and available as
a plugin, because they work so well together. This is sort of where the
smart-urls plugin  ( a great piece of work, too ) comes in.  Maybe effort
should be placed into that to plump that up and 'robusticate it' ( as my
co-worker likes to say )

In my perception of the near-future world, some additions to zc/cb or
smart-urls . some flex-json style ability for the json plugin, a bit of
guice and warp, and you've got a very easy development cycle.

Re: How to improve dojo performance in Struts 2.0.9

[cilquirm]

Sorry to hijack this thread, because I fully agree with Wes that this is
good stuff to put into a wiki.
It's a little trickier with the apache wiki because you need to sign and
send over the CLA ( not terribly hard, but sometimes may not be possible. )

Any thought given to using a secondary wiki ( like Wetpaint or one of the
other myriad of services that come up when you type in wiki into the
mashable search box ) to ease the burden?

Re: How to improve dojo performance in Struts 2.0.9

[cilquirm]

I hadn't really started fragmenting anything  yet.  I was engaging in
conversation.

I'm not sure if you checked recently but the apache wiki is slow to get
updated.  I don't disagree that having a centralized place for it is
definitely the best route, but there's tons of information out there that
isn't in the wiki for one reason or another.  You're bound to end up
googling or going to your know spots , so the fragmentation issue is less
valid than you would presume.   I find it less about decentralization than
"re-centralization"

My whole point was to get around the barrier of entry of engaging people to
add and modify stuff.  Getting someone else to maybe do it doesn't seem like
a form of engagement.

Re: [S2] Manually obtain previous action parameters after action "chaining"?

[cilquirm]

You can, if you grab the ValueStck and traverse up it till you get to your
previous action.

Re: [S2] Change struts-default.xml content

[cilquirm]

you can redefine it in your struts.xml, much like how you would specify the
object factory to override the default object factory .

Re: [S2] Change struts-default.xml content

[cilquirm]

I think the problem might be that there may not be a way to configure a
different TextProvider.

Consider the object factory example, in this case guice :



  

  
  




What this does is create a bean provider with a given name of that type.  

The constant portion is actually the configuration piece.

I tried looking in the source, but I couldn't find how to configure the
textProvider.  
The two pre-configured ones both use the same class so one wouldn't note any
difference.

Maybe someone on the list can help you out more.

Apologies,

A failed type conversion will incur a field error as well.

Re: S2: EL in tags 2.0.11

[cilquirm]

I believe this was a security fix, as there was an issue where ognl
expressions could be used to do something drastic to the application server
( like System.exit ).

I believe the expectation is that you can get around it by creating your own
customized tld or something like :

RE: S2: EL in tags 2.0.11

[cilquirm]

you could do this








Basically, stuff the object into the pageContext somehow and then reference
it again via ognl.

It's a pain, but a very slight one.

Re: [struts] S2: EL in tags 2.0.11

[cilquirm]

I could be wrong ( and I hope I am ), but I thought the request object in
that case was just a map facade to the underlying request attributes map.

Which is why I supposed you say #request['foo'] vs.
#request.getAttribute('foo').

Same goes for session.  ( #session['foo'] vs  #session.getAttribute('foo') ) 

I just checked Dispatcher and it seems that #request and #session are
instances of RequestMap and SessionMap respectively, in which a Map wraps
the access to getAttribute.

If these were extended to have a getRequest/getSession method, then we might
be able to say 

#request.request.contextPath.

RE: [struts] S2: EL in tags 2.0.11

[cilquirm]

My apologies if it was misinterpreted.  I did not say it WOULD work, I said
it would take some effort to get it to work, but that it does not work.

At this point, I believe you have a number of options :

1) You can use the method i showed you :

 



2) You can build your own custom copy of struts2 that has the tld with the
rtexpr value enabled, but be advised that you are reenabling a security
risk.


3) you can not use s2 tags, if you're that reliant on the jstl/el expression
language.

Re: javax.el.ExpressionFactory

[cilquirm]

This is most probably not related to Struts.

I can't claim to know the intrinsics of your setup but it looks like you're
missing some jars need for JSF.
It might be that you're running an older version of the J2EE stack.

javax.el.ExpressionFactory comes with J2EE 5, and is part of JSF 1.2

Re: javax.el.ExpressionFactory

[cilquirm]

Did you see what happens when you take out the interceptor?

As I see it, you should still be getting this error ( since I postulate they
are unrelated :) )

If not, then this indeed is a mystery.

Re: Validation dies because of request param array?

[cilquirm]

Do you have struts.devMode = true?

I had the same problem and I was forced to change struts.devMode = false

I believe this is a change from 2.0.6  ( and in some regards, a worse one at
that ).

I'm still investigating it, but please try turning devMode off and seeing if
it helps.

Re: Validation dies because of request param array?

[cilquirm]

I should correct myself. My problem may not be related, since it was due to
the CookieInterceptor's handling of setValue.

Can you post your pojo and your query string?

Re: [S2] how to configure Spring's OpenViewInSessionInterceptor for struts2

[cilquirm]

I think you may be confusing Struts2 (S2) interceptors with Spring
Interceptors.
The two are not the same.

S2 interceptors provide some "aop-like" functionality by allowing code to
modify request processing in some fashion; however it's not truly based
around an aop standard ( i.e. aopallliance ) ( s2 devs, please feel free to
correct and chide me. )

The OpenSessionInViewInterceptor ( OSVI ) is an analog to the
OpenSessionInViewFilter (OSVF), but I belive it's primarily used for
SpringMVC ( and possibly related, like Grails ).

OSVF is more generic and designed to be used in a larger number of
frameworks.
I believe, in this case, what you probably want is the filter.

the easiest solution would be to s:set the property name you want to
reference with a different name



and then access it in your loop under the new name.

Re: [S2] how to configure Spring's OpenViewInSessionInterceptor for struts2

[cilquirm]

Assuming your S2 actions are 'pathed' differently ( i.e. s2 actions are
mapped to .action , while s1 actions are mapped to .do ), then specifying
the url pattern only for s2 actions ( /*.action ) will have the intended
effect.

As far as side effects go, it's really dependent on your application.  The
ones they mention on the docs relate to  moving an application that hasn't
been using open session in view to that pattern.  You may have objects that
you keep around for a long time ( i.e.  in a  http session ), which you then
reattach to the session when you want to do do work against it.  When you
have ad-hoc session management, you might have gotten away with
reattaching/detaching/flushing/updating whenever you feel like it because
you're creating a new hib session whenever you need to..  

With OSFV, since the session is already created upon request, you may end up
with a couple exceptions because the session is always there and those
operations ( depending on when you do it, and in what order ) may throw
exceptions.  

At best I can tell you, as the docs do, is to minimize the objects you keep
around for a while.  For those that you do, reattach them early on, and
watch your transaction boundaries.  

Ask away if you have particular questions :-)

Re: RE : Orthognal OGNL!

[cilquirm]

technically, if you knew the index of where the action was in your value
stack, you could use the index notation.
so you might want to try :



assuming the action is the second root down.

but i do agree that'd it be nice to stuff the action into #action.

You wouldn't need to if you loaded and discarded your objects in a single
request, but let's say you have objects that lived around longer than a
single request ( i.e., a User object in your http session ).   You might
have  reattached this object to the session every time you wanted to make a
modification to it, because you were creating hibernate sessions on the fly. 
With OSFV,  you might end up with errors because after the first time, the
object is already attached to the session.  

That's probably the most common use case.

What i meant by watch transaction boundaries is simply take note where and
how you decide to mark off a transaction.  For example, if you weren't using
Spring's declarative ( or aop-based ) transaction management, you might have
a session.beginTransaction() in one method, and a session.endTransation() in
another method.  If you were creating hib sessions on the fly, if you rolled
back, you can simply wipe out your session and create a new one and go on
your (relatively) merry way.  With OSFV, that session that you rolled back
against is still there, so maybe your objects that you haven't persisted are
not in the db, but still associated with a session.The same thing can
obviously occur with Spring's transaction management as well, but at the
heart of it, I meant that's something to keep in mind.

RE: [S2] Servlet-Config Interceptor Bug?

[cilquirm]

The session object is wrapped by a SessionMap, so every time you do a put or
remove, the appropriate underlying method on the session is called.

So, in a nutshell, no, nothing to worry about.
Like most of struts2, it just works :-)

Re: Struts 2 performance

[cilquirm]

I've found that static html pages are blazing fast, especially those that
don't involve stylesheets, images, or javascript includes.  :-)

Seriously, though, I don't think there's any disagreement that ognl ( or any
runtime expression language ) adds a certain amount of overhead, but I've
never seen any of my servers pinned that high, and I've been working with
WW2/S2 for probably around 3 years now. 

At the end of the day, I can argue to my company that we'll get faster
performance by switching to servlets and straight jsp, but I don't want to
be the one debugging that when it all goes to pot. I'm all for the minor
tradeoff on performance for the incredibly superior gains in productivity
and general developer happiness that S2 affords me.

my2c, 
-a

P.S.  One thing you can do, if you're so inclined once you've tried out the
other performance tips, is to give ognl 2.7 a go.  You can get it via the
Tapestry libs download.  It's a straightforward replacement, just drop in 
ognl.jar and javassist.jar and start up.  

I've done it here and it hasn't really changed my perception of my webapp
but YMMV

Re: Struts 2 performance

[cilquirm]

Frank, would you care to give the same tests a shot with  ognl 2.7 and
javassist in the mix.

Although none of this is purely scientific, at least evaluations on that
regard give us some level of subjective information.
 
The ognl 2.7 and javassist jar are available via the tapestry-4.2-libs
download :

Re: Configuring Struts with eclipse

[cilquirm]

It's relatively easy.

You want the WTP  ( unless you're using some customized version like
MyEclipse, at which point, I can't help ).

a) Create a Dynamic Web Project.
b) Set up your Server Runtime (1) (2)
c) Drop your jars into WebResources/WEB-INF/lib  (3)(4)
4) write up your struts.xml :



http://struts.apache.org/dtds/struts-2.0.dtd";>











5) set up your web.xml :


http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";>


struts

org.apache.struts2.dispatcher.FilterDispatcher


actionPackages
com.thestreet.web.actions




struts
/*





6) happy coding.

hth,
-a

(1) if you're using Eclipse Europa 3.3, you can use the J2EE preview to run
an embedded version of jetty so you don't even need an external runtime.
(2) certain servers, like glassfish and geronimo, can actually be installed
directly from this setup screen.
(3) at the very least you'll need the struts2-core, ognl, commons-logging,
xwork, 
(4) fwiw, I like to use the codebehind plugin ( or at your leisure, use the
smarturls plugin )

Re: Open Source Struts Dating Application

[cilquirm]

I think you have to 'know' somebody to get it incubated.  i.e.  Just because
you're offering, doesn't mean they'll bite.  (And I don't mean that in a bad
way, either.  )

Check out the incubation docs for more info :

http://incubator.apache.org/incubation/Incubation_Policy.html

Barring that, you're free to open it up to the world on sourceforge,
dev.java.net, or googlecode.

I do think that having an advanced application is a good real-world testbed
for a whole slew of things.

I'm assuming it's an S1 app?

Re: FieldExpressionValidator: How do I reference field names?

[cilquirm]

That's a mouthful.

OGNL does have an 'in' operator

customer.creditCards[0].type in [ 'AMERICAN_EXPRESS', 'VISA', 'DISCOVER' ,
'MASTERCARD']

note that you don't have to do toString() if type is already a string ;
ognl's equality operator ( == ) already uses equals.

If it's not of type String, you might try projection :

[ 'AMERICAN_EXPRESS', 'VISA', 'DISCOVER' , 'MASTERCARD'].{? #this.equals(
customer.creditCards[0].type ) }.size() > 0

Re: Configuring OpenSessionInViewInterceptor as S2's interceptor

[cilquirm]

In my experience, just having OSIV doesn't automatically imply that you
expect all your data to be retrieved ad-hoc. (maybe the users do :) 

  OSIV doesn't prevent the user from using eager fetching when necessary or
useful ( and my experience delays it until your application is working and
you're onto improving performance ).  There's no reason I still can't
Hibernate.initialize() or  fetch join when I want to bring down the number
of round-trips to the database.   OSIV does provide a big boost ( to me, at
least ) in being able to do rapid turn-around development.

You can have a single action with multiple execution methods that return the
same result name to different result values.  i.e.

public class MyAction extends ActionSupport {

  public String prep() {
...
   return SUCCESS;

  public String submit() {
... 
return SUCCESS;
  }
}

could be defined as 


  
/my/dir/myjsp1.jsp
  
  
/my/dir/myjsp1.jsp

I think what Richard is suggesting is something akin to this  :

public class AwesomeAction extends ActionSupport implements Preparable {
  
  List awesomeList;
  AwesomeService awesomeService;
 

  public void prepare() {
 
 awesomeList = awesomeService.getList();
  }
  
  public string prep() {
 return SUCCESS;
  }

  public String submit() {
 [ do checks ]
 if ( !everythignChecksOut )  return INPUT; 
 return SUCCESS;
  }
}

In such a scenario, yes, prepare would be called on the submission.   You
can work around it in this manner.

public class AwesomeAction extends ActionSupport implements Preparable {
  
  List awesomeList;
  AwesomeService awesomeService;
 

  public void preparePrep  /* how droll! */ () {  
 
 awesomeList = awesomeService.getList();
  }
  
  public string prep() {
 return SUCCESS;
  }

  public String submit() {
 [ do checks ]
 if ( !everythignChecksOut )  {
 preparePrep();
 return INPUT; 
 }
 return SUCCESS;
  }
}

you could work around that in this way, a little wonky, but still
sustainable:

public class AwesomeAction extends ActionSupport implements Preparable,
Validateable {
 
  List awesomeList;
  AwesomeService awesomeService;
 

  public void preparePrep  /* how droll! */ () {  
 
 awesomeList = awesomeService.getList();
  }

  public void validateSubmit() {
 if ( hasErrors() ) { 
  preparePrep();
 }
  }
 
  public string prep() {
 return SUCCESS;
  }

  public String submit() {
 [do eet];
  }
}

Re: Joining list with OGNL

[cilquirm]

I don't believe OGNL supports concatenation of lists, but such functionality
could be achieved using chained subexpressions :

( ticketStates.add(0,new MyObject(-1,"All")), ticketStates )

which would insert the new object into the head of the list, and then return
the ticketStates object as the return value.

Re: [S2] Conditional Validation (test if field is present in JSP)

[cilquirm]

somewhat hackish, but you can accomplish this by using expressions :

#params['attrib'] != null ? attrib in ('a','list','of','values')

(this is just an example stating that you can check for the existence of the
variable in the parameter and then execute an expression like you normally
would )

Re: Whats the harm in creating a Servlet Dispatcher?

[cilquirm]

I'm pretty sure that making FilterDispatcher a Filter was a design decision
so converting it to a servletdispatcher may not be as easy or as
straightforward as one might think.

If memory serves ( and these days, that's not guaranteed ), it actually used
to be a filter/servlet combination before it got rolled up in to a filter.

For example, it wraps the servletrequest so that the EL can have access to
the value stack.  Also, it allows for the static dispatch of the templating
themes.

Coder emptor, is all.

Re: [S2] Conditional Validation (test if field is present in JSP)

[cilquirm]

You can manage conditionals by using expressions and fieldexpressions , so
your validation below would become :



 (#params['myInputFieldName'] neq null)  && ( myInputFieldName
neq null & myInputFieldName.trim().length()  gt 0 )

RE: S2 : Validation per Action method - ideas?

[cilquirm]

I'm not sure I follow how validation is more flexible when using annotations
vs. xml files.

Aliases are how you tell xwork that this method is the one to be executed,
so there's a 1-to-1 mapping between aliases and methods.

File based validation is, in a sense, more flexible, because you can define
multiple aliases against a single method and specify different rules for
each of those.

If you could provide more information regarding your situation, that would
be of great insight.

Thanks,

Re: ParameterInterceptor

[cilquirm]

I'm not sure I follow this 100%.

Are you saying that a single null propery being passed into the setter of
your model caused a whole new model object to be created?


So you have : firstName, lastName, and address1 
address1 was read-only ( disabled or whatever you want to call it ).

your action is ( for example ) : 

public class MyAction extends ActionSupport implements ModelDriven {
 
  private User user = new User();
  public User getModel() {  return user ; }

}

then because address1 was null, a new user was created?

I'm partly confused because disabled properties shouldn't even be
transmitted by the browser ( though some ajax libraries are faulty when
'serializing' a form for use via XMLHttpRequest ).

You can also map each method to a name in your struts.xml by using the method

Re: Mapping multiple enums to a nested object

Are enums type-converted automatically now?

I recall early on I  had to specify
http://struts.apache.org/2.0.9/struts2-core/apidocs/com/opensymphony/xwork2/util/EnumTypeConverter.html

Have you tried specifying that?

with

Re: Mapping multiple enums to a nested object

[cilquirm]

Indeed, the problem is that EnumTypeConverter, as provided by Struts2  only
works for single values.

Can you make selectedNutrients a List?

If so, you might be able to use the EnumTypeConverter from the showcase app,
or roll your own based off it, which isn't that hard at all.

org.apache.struts2.showcase.conversion.EnumTypeConverter

Re: Mapping multiple enums to a nested object

[cilquirm]

Doesn't seem that way.
One converts a single string value to an enum, and the other converts a
String[] to a List

I just checked it over and it's not directly useable because it's a type
converter for a specific enum ( OperationsEnum ), but the principles apply.

The long and the short of is that you'll have to write your own type
converter, but checking out the example from showcase is a fairly good
starting point that should get you at least halfway.

One other thing that's nice about Struts2/WW is that you can utilize the
ModelDriven interface on your action.

So your action is 

public class MyAction implements ModelDriven {

  private MyBean myBean = new MyBean();

  public Object getModel() { return myBean; }

}

that way your form fields can still be referenced by 



Also very useful when moving your properties from the action into a
model/domain object/value object/etc... because your front-end code does not
hae to change.

[S2] possible NPE in Restful2?

[cilquirm]

Hi, I think I noticed an NPE in Restful2, which is set as my default action
mapper. I'd like to resolve it but I'm not sure my logic on the matter is
correct and hopefully someone on the list can set  me straight :

The error : 

java.lang.NullPointerException
org.apache.struts2.dispatcher.mapper.Restful2ActionMapper.getMapping(Restful2ActionMapper.java:97)
org.apache.struts2.dispatcher.FilterDispatcher.doFilter(FilterDispatcher.java:393)
org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202)
org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173)
com.opensymphony.module.sitemesh.filter.PageFilter.parsePage(PageFilter.java:119)
com.opensymphony.module.sitemesh.filter.PageFilter.doFilter(PageFilter.java:55)


The offending code :

public ActionMapping getMapping(HttpServletRequest request,
ConfigurationManager configManager) {

ActionMapping mapping = super.getMapping(request, configManager);

String actionName = mapping.getName();


The logic :

Since restful2 is subclassed from DefaultActionMapper, the super call does
the work that the defaultactionmapper would do and then runs its own checks.

The problem happens when you use codebehind and restful2 ( as I am ), and a
mapping is not returned.  Then, the mapping is null, and getName() fails.

So the solution would be to check mapping for null before proceeding.


Again, I'm not sure of the intrinsic details of it, but I applied such a fix
locally and it seems to work smoothly ( though I don't have the plethora of
tests that maybe others have, but the surefire stuff runs ).


Please let me know if I am of the right mind, and I'll submit an issue and
patch.


Thanks,
-a

(oh and sorry for not posting in struts-dev. I don't belong to that list yet
and this was slightly faster.)

Re: [s2] how to make s:iterator work

[cilquirm]

I don't know particularly about the s:iterator, but since you said you're
using JSP, you can access the model via the jstl tags just as easily :


  ${book.author}



though, looking at your code again,  I suspect it's because your getter is
class private.

It would have to be public.

[cilquirm]

scratch my original comment ( though the part regarding using the jstl is
still valid. )

the problem for you is that since listOfBooks is not in the valuestack
directly, you would have to reference it via the request object, like so

Re: [S2] Prepable and Validate

[cilquirm]

I don't think this will work as you expect it to for 2 reasons :

1) prepare comes before validate ( at least in all the interceptor stacks
that i saw, obviously you're free to change the order )

2) validation, at least in my perusal of the source, doesn't short circuit
the interceptor stack

RE: [s2] String comparison with OGNL -- Learning OGNL by stabbing in the dark.

[cilquirm]

Just FYI,
I think this lesson was less about OGNL per se, and more about
Java,Servlets, and the Parameter map.

#parameters.addrType is of type String[], because that's how it's collated 
( since you can have multiple values to a single name.. )

Re: how to use struts2 + spring + JPA

[cilquirm]

your persistence.xml must be in META-INF directory in the classpath ( so
basically, it needs to end up either in your jars in WEB-INF/lib or in your
WEB-INF/classes directory )

As far as I've seen and worked with, other than keeping the "org.apache"

Re: how to specify ActionMapper

[cilquirm]

The error seems self-explanatory.

By specifying the "queryReportBeanName" inside the  tag, you're
actually setting the value on the redirect-action object ( known also by
it's java name org.apache.struts2.dispatcher.ServletActionRedirectResult ).

if you want to set a static param on your own action ( also known as
com.xyz.customersolutions.ess.webapp.action.common.BaseAction ), then take
it out from under the  tag and put it in inside the  tag.

Re: how to specify ActionMapper

[cilquirm]

My apologies. I read the message wrong.

Is the problem that the the value is not being set on the action being
redirected to?

Looking at the error message, and the source, it's just a warning. 
Processing continues as normal after that, so it should be setting the
values correctly.

I've not used 'redirect-action' with extra parameters like below, but I have
done so using 'redirect' ( and the former is extended from the latter ) with
success.

Re: [S2] struts2 validation for only one method in action

[cilquirm]

I believe you can use validation annotation to specify validation routines at
the method level.

s2: numbers being formatted during display in s:select tag

[cilquirm]

This is so odd, yet I'm surprised no one's come across this.

This is S2 built off the 2_0_X branch ( no modifications, straight clean
build ), running under Java 1.5  in both resin and tomcat.

Given a snippet like so :




the output of the id is a formatted string :


Please, Helpme 
Being, Earnest
...


(names have been changed to protect the innocent )

Anyone else come across this.

Is this a bug? Known workaround?

Thanks for any input,

aadi

Re: [S2] JNLP with struts ?

[cilquirm]

in your resulting page
you can set

@page contentType = 'application/x-java-jnlp-file'

and return the body of your jnlp file ( possibly even read via c:import or
some such mechanism )

RE: Struts 2 Action Classes (HELP!)

[cilquirm]

That example is using the null property handling feature of the XW
type-conversion system :

http://struts.apache.org/2.x/docs/type-conversion.html

Basically, when xw/ognl  sees ( evaluates )  person.firstName, it calls
getPerson() , which returns null.
XW goes to work and creates an empty Person object and places it on that
action.
and then sets firstname on that newly created person object.

(n.b. the exact ordering may be slightly off, it might set first name first
before setting person object, but the end result is the same, in this case )

I'm not sure how your spring configuration is set up, but that would be
helpful  to see.
Myself, I don't use the constructor injection mechanism, i use
autowire-by-type, so my Action doesn't have a specifically declared
constructor, just a 

setUserService(UserService us) { this.userService = us }

RE: Problems using spring plugin and struts 2.0.6

[cilquirm]

Technically, this isn't necessary when you have the struts-spring-plugin.jar
in your WEB-INF/lib
since it's already specified by the struts-plugin.xml file

I think, however, seeing a more complete stack trace for the CNFE would be
helpful since I have 2.0.6 with the spring plugin just fine.

Re: [S2] Problem with 2.0.6

I see errors like that on occasion ( mine is with the JSONResult type and the
location property ), but they've always been warnings.

Is yours logged at the ERROR level?

Re: [S2] Problems using spring plugin and struts 2.0.6

[cilquirm]

I'm not sure type converters are instantiated via the ObjectFactory
mechanism, but you can just as easily say :

domain.security.PermissionType = presentation.converter.EnumTypeConverter

You will probably need to refactor some code if your EnumTypeConverter
expects to be in a Spring context.

You could wipe it out of your logs by setting the class that throws it to

Re: [S2] TypeConverter

[cilquirm]

I do it like so :

Map contextMap = ActionContext.getContext().getContextMap();

ApplicationContext applicationContext = (ApplicationContext) ((Map)
contextMap

.get("application")).get(org.springframework.web.context.WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE
);


This I discovered using a bit of trail and error.
I'm not sure if there's a better way to retrieve the servlet context from a
TypeConverter, but if there was,
you'd be able to use WebApplicationContextUtils, from the spring api.

Re: [S2] forward to another action

[cilquirm]

why can't you add parameters in chain?

In your action, can't you :

 1)  implement ParameterAware
 2) set a parameter value in the map that's passed in
 3) chain to your action
 4) have the value be set in your chained action, via the params interceptor

Re: [s2] How to pass param to actions from Struts.xml

[cilquirm]

Create a setter with the same name as your param.

ex :

for :
This value


in MyAction :

public class MyAction implements Action {

  private String myValue;

  public void setMyValue( String value) { this.myValue = value; }

}


Type conversion's done on this param value just like any other parameter.

Re: {S2] Newbie: Sharing a POJO between two or more actions

[cilquirm]

If your actions occur in sequence, ( 

 i.e. submit to an action -> display action

), 
 it's possible to use action chaining to  share objects.

Re: Validation on java.util.List

[cilquirm]

I don't know if this helps, but when I validate a list or array , i use
OGNL's selection/projection facility :

i.e. :

customers.{ ? #this.age gt 0  and #this.username neq null }.size()  eq
customers.size

creates a list of all customers whose age is greater than zero and who have
a username and checks that it is the same as the incoming array ( i.e.
everyone has a username and an age ) 

For the second part,

in your Object's  -conversion.xml  file
declare the type information of the element, like so :

Element_customers = my.Customer

Re: OSS tool to diagram struts-config.xml ?

[cilquirm]

There are a number of tools in the Eclipse space that can do this ( i.e.
they run as Eclipse plugins/features and using the underlying GEF framework
).

One that I can think of off the top of my head is StrutsIDE :
http://amateras.sourceforge.jp/cgi-bin/fswiki_en/wiki.cgi?page=StrutsIDE 

Exadel Studio also has one. They're not OSS yet, but having been bought by
Red Hat, they will be in short order.

Re: Handling login for struts 2.0

[cilquirm]

I think the answer is a 2 part solution, but you're on the right track.

1) Create the interceptor that returns Action.LOGIN ( or whatever it is when
the user isn't authenticated ).

2) set up your login page in your global results type. See this page for
more information :
http://struts.apache.org/2.x/docs/result-configuration.html

That should really be all that needs be done.

Having been down this road,  I would venture with the "Don't bother." side
of the argument


In my opinion, while the price is fantastic, you're generally stuck with
versions that lag behind their completely free implementations ( i.e. the
hibernate console from the jboss ide and their wsdl support ), or don't work
as well as alternative plugins/features ( say, for example, the data access
tools ).

My advice is to get Eclipse from one of the Callisto distribution sites, and
configure it yourself using the Update Site.  

The Eclipse WTP is, for the most part, really well done and supports
everything you need for S2 development out of the box. 

However, this is one of those things where your knowledge, expertise, and
familiarity with Eclipse play a big role.  

I think, however, this is a great opportunity for someone to become much
more familiar with the Eclipse ecosystem, and learn to pick and choose the
tools that work closer to the way you want.

So true.   WW never had any good tools ( to my recollection ) either.

But, because S2 relies a lot less on the "heavy-OO" conventions that make up
S1, pretty much any IDE is suitable for S2 development.

Here, because we're using ClasspathConfiguration, Codebehind, and
Annotations, there's only been a tiny amount of locations where we have had
to go to the configuration files to make the magic happen.

Re: Struts 2 URL mapping

[cilquirm]

You actually can do that with the default mapper, using wildcarding.

Here's an example of what we do :


{1}


The only trick is that you have to remember to suffix your url appropriately
when calling so that S2's dispatchfilter is able to run and pick up on the
url mapping.

i.e. ( our struts.action.extension is 'page' ) :

http://mysite.com/view/23.page

calls the execute method of the ViewAction and sets 23 to the ID.

Multiple mappings are allowed as well :


{1}
{2}


to execute :

http://mysite.com/view/movies/16.page

Of course, this implies that for every distinct format of urls that you may
have, you need a mapping set up.  If you have a lot of variety, this could
be problematic.

Otherwise, like Dave mentioned, you can look into using RestfulActionMapper.

I haven't really used Restful (more experience with Restful2) much, but it
seems that it imposes a constraint on you of having your urls of the fashion
:

http://mysite.com/myaction/paramName/paramValue 
 or
http://mysite.com/myaction/myid  ( shortcut ).

If you only have one parameter, or if you don't mind your urls in that
format, it could work for you.

One final comment.  I'm not sure how the default setup is anymore, but my
configuration has 'struts.enable.SlashesInActionNames' to be 'true'.  If you
have trouble with the above ( assuming you try it ), you might want to check
to see if that config param is the same.

hth,

Re: Struts 2 URL mapping

[cilquirm]

You actually can do that with the default mapper, using wildcarding.

Here's an example of what we do :


{1}


The only trick is that you have to remember to suffix your url appropriately
when calling so that S2's dispatchfilter is able to run and pick up on the
url mapping.

i.e. ( our struts.action.extension is 'page' ) :

http://mysite.com/view/23.page

calls the execute method of the ViewAction and sets 23 to the ID.

Multiple mappings are allowed as well :


{1}
{2}


to execute :

http://mysite.com/view/movies/16.page

Of course, this implies that for every distinct format of urls that you may
have, you need a mapping set up.  If you have a lot of variety, this could
be problematic.

Otherwise, like Dave mentioned, you can look into using RestfulActionMapper.

I haven't really used Restful (more experience with Restful2) much, but it
seems that it imposes a constraint on you of having your urls of the fashion
:

http://mysite.com/myaction/paramName/paramValue 
 or
http://mysite.com/myaction/myid  ( shortcut ).

If you only have one parameter, or if you don't mind your urls in that
format, it could work for you.

One final comment.  I'm not sure how the default setup is anymore, but my
configuration has 'struts.enable.SlashesInActionNames' to be 'true'.  If you
have trouble with the above ( assuming you try it ), you might want to check
to see if that config param is the same.

Re: How to get a attribute value of map value?

[cilquirm]

The second way, %{test['AnyString'].att} or even, explicitly,
%{test['AnyString'].getAtt()} should both work.

I know it might sound dumb, but is there a value to att? ( using that class
as an example, there's no way to set it :-)

Re: [S2] Adding Calendar function to a form.

[cilquirm]

Struts 2 tags support pretty much all the attributes that their html
counterparts do.
I haven't used NewCal ( seen it, but not used it )

but you can try something like this :


javascript:NewCal('myfield','ddmmm',true,24)  images/cal.gif

Re: struts.action.extension question

[cilquirm]

I don't believe this can be cleanly handled with just the web 2.4 spec and
struts2.

Some container, like Resin, allow for url-patterns to be regexes, which
would help in this scenario.

Re: returns an String[] when is checked!

[cilquirm]

Try declaring a boolean setter in your Action with the checkbox name.

i.e.  

setCheckboxName( boolean val ) { this.checkboxName = val ; } 

and using that instead.

I'm not sure why you're trying to get the value from the
ActionContext.getParameters().  That will return the raw, globbed values of
the parameters, and they by nature are multi-valued, so a String[] is
expected. 
( it's possible for a query string to be someParam=a&someParam=b ).

Re: [S2] Adding Calendar function to a form.

[cilquirm]

it is possible, if you extend and modify whatever theme you're using.

Then you can put that code wherever you want it to show up right inside the
freemarker template that renders it.

Re: struts.action.extension question

[cilquirm]

I believe I didn't follow the original issue, then.

I thought that struts2 was swallowing the requests for the css files because
they fit the pattern specified by the filter.
I can't see how making them absolute urls would be any different for the
filter, because when the request is made by the browser, it all looks the
same to the filter.
