NoSuchMethodException

[volker]

Hi,

I have an Action class called RentalObjectAction that is inherited by a class 
named I18nBaseAction. This I18nBaseAction contains a method called 
switchLanguage (public).
When I try to call switchLanguage, which sets a value and returns SUCCESS,
I get a NoSuchMethodException. 
What is my fault ? Isn't int possible to use Methods in Subclasses ?

Regards

   Volker

sx:tree and sx:tabbedpanel do not integrate

[RajibJana]

Hi All,

I am building a application using struts 2.1.2.

In my application, I want to have tree and by clicking a tree node, an
action will excute and attached JSP with the action will have a tabbedpanel.
( just like a standard java GUI).

I have searched the showcase examples and found out the dynamic tree example
where action is invoked by clicking the tree node. Below is the code:

--

dojo.event.topic.subscribe("treeSelected", function
treeNodeSelected(node) {
dojo.io.bind({
url: "?nodeId="+node.node.widgetId,
load: function(type, data, evt) {
var divDisplay = dojo.byId("displayId");
divDisplay.innerHTML=data;
},
mimeType: "text/html"
});
});




 


Please click on any of the tree nodes.

-

The result jsp of dynamicTreeSelectAction displays the nodeid and nodename
in the div tag.

If I put a sx:tabbedpanel in this result jsp, then tabbedpanel does not
render at all, in stead the content of panels are shown only( not the visual
tabs).

I put the alert to see the innerhtml, it shows the correct content.

Where I went wrong?

Please help.


Regards

Rajib

Re: Extending Struts 2 Tags

[Alberto Flores]

I believe that at some point in your quest you are going to learn that 
Struts2 tags delegate to a component (which you'll have to extend/use). 
So a few questions (if overriding the label setter doesn't work).


- Are you using the "key" attribute on the tag (it's used to generate 
the label).

- Are you using the "label" and "key" combined?

From the Struts2 source code (UIBean)

public void evaluateParams() {
addParameter("templateDir", getTemplateDir());
addParameter("theme", getTheme());
addParameter("dynamicAttributes", dynamicAttributes);

String name = null;
String providedLabel = null;

if (this.key != null) {

if(this.name == null) {
this.name = key;
}

if(this.label == null) {
// lookup the label from a TextProvider (default value is 
the key)

providedLabel = TextProviderHelper.getText(key, key, stack);
}

}

if (this.name != null) {
name = findString(this.name);
addParameter("name", name);
}

if (label != null) {
addParameter("label", findString(label));
} else {
if (providedLabel != null) {
// label found via a TextProvider
addParameter("label", providedLabel);
}
}

}

So as you can see, the label (if not null, is expected to be resolved by 
the findString() method. Please take a look at the source code for 
further info. I have been overriding my messages (using the key) 
successfully (and not using labels).


Hope this helps!

Unit testing Struts 2 systems in multiple projects

[Peter Butler]

We are doing web development using Struts 2, building using Maven. Our
system is made up of two projects: a war project and a core project. The
war project contains all web resources, jsps, etc. The core project
contains all of our struts actions, service layer and data access layer.

 

We split our system up like this because of the Maven restriction on
generating one artifact per project. The problem is that this makes
automated testing difficult. The web project contains the struts.xml
file that defines all of our actions but the action source code is in
the core project.

 

How can we set things up so that the test code can pick up the
struts.xml file from the web project while testing the code in the core
project? I have been thinking about putting the tests in the web
project, but this means that the test code is in a different project
from the code that is being tested, which is not ideal. The other
alternative is to have separate struts.xml files for testing and
deployment, which is also not ideal.

 

How have other people handled this?

 

Cheers

 

Peter

IMO that's broken--the S2 actions should be part of the web project because... 
that's what S2 is--the web layer. That solves your problem and (to me, anyway) 
seems a more logical approach.

Ordinarily I would agree with you, but we have a constraint that I
forgot to mention: our actions have to be usable in more than one web
project. The system we are building is deployed to more than one
customer. We customise the web project by overlaying customer-specific
files in separate projects.

I was thinking that another approach to this might be to keep all
actions in the core project, along with the struts.xml file, then
package these into a jar file. This page:

http://struts.apache.org/2.0.11.2/docs/can-we-break-up-a-large-strutsxml
-file-into-smaller-pieces.html

says that this is possible, but doesn't give any details. Does anyone
have any more details on getting this to work?

Cheers

Peter

Help in resetting multiple form data

[Sulabha Walavalkar]

Hi,

 

I am using 4 forms in one jsp, the reason being few select UI components &
search are common to other use cases. 

The problem I'm facing is with resetting the fields on successful completion
of any transaction.

 

One option is calling reset() method on all the forms in java script
function on onload even of body. But my application is using tiles & master
layout jsp because of which my function on body onload is not getting
called.

 

Can someone help me out giving any options to clear the data for all the
forms displayed in jsp?

 

Thanks & Regards,
Sulabha 

 

html:select in firefox

[Jeffrey Born]

I'm trying to use a JavaScript function getElementById to access the
selectedIndex property of an HTML select tag that is generated via a
struts html:select tag.  The JavaScript function is failing because
the Id attribute is missing.  IE works with the name attribute which
is generated.

I'm using struts 1.1.

I could override the html:select tag to output an Id attribute, but
there has to be a more elegant solution to this?  Or it was solved
some other way?

Any tips would be greatly appriciated.

[S2] not including null-params in URL of GET-submitted form

[Pierre Thibaudeau]

Is there a way to avoid null-valued (or empty-valued) parameters to be
explicitely mentioned in the URL generated by a form submitted through the
GET method?

For instance, here's a form:







If the user types "FOO" in the first textfield and nothing in the second,
the submitted URL will be something like:
http://myhost.com/myAction.action?param1=FOO¶m2=

Can I get rid of the "param2=" part, which serves no purpose?

(The alternative would be to POST the method to an action that would merely
redirect to the desired action, dropping the undesired parameters along the
way.)

Re: html:select in firefox

[Jeffrey Born]

The styleId attribute did the trick.  To quote the great homer simpson:  "doh!"

When it was not there, firefox responded exactly like it should.  The
method is getElementById not getElementByName.  getElementByName works
just fine under IE however since under IE it uses the name attribute.

Thanks again for solving this for me.  It was driving me crazy!

Question about request/sessions

[rageice]

Hello, sorry for my bad english.

I am working on an application that uses a framework, and this framework
uses itself struts.

There is something I can't understand:
In a request, 2 actions are caled the one after the other (nothing other
action between the two actions).

In the first action, the session contains an attribute, and in the second
one, this attribute is null.
Do you see any reason for this?

AjouterUserGroupeAction is the first one

  


InitAction is the second one.

  
  ...


And the code in the "process" methods can't be the cause of this problem...


Thanks in advance for any help.

Struts 2: How can we save the parameters if we do redirect and not redirect-action

[srinivasch]

Hi,

   My issue goes like this, I have a summary page which comes for a search
result, and the user clicks to see summary of any record from the result. So
all the search parameters are existing in the URL. And when we further hit
edit link of the summary record, and again when the user hits cancel or
save, the URL parameters which were forwarded to the summary page wont
exist. I would like to retain the parameters. Appreciate your quick response

Here is the snippet of my struts config how I used the result


/view.action?linID=${linID}

Re: Struts 2: How can we save the parameters if we do redirect and not redirect-action

[daveck]

I ended up solving a similiar problem using an Interceptor and saving the
parameter Map to the session.

session.setAttribute("input_params", request.getParameterMap();

Then in my action I implemented SessionAware and utililized BeanUtils from
Jakarta Commons to re-populate the properties in my action class.

this.setRequestMap((Map)this.getSession().get("input_parms"));
BeanUtils.populate(this, this.getRequestMap();

Hope this helps.

RE: [S2] solution - Action chaining and validation problem

[Becky . L . O'Sullivan]

The culprit wasn't the validation interceptor, but the workflow
interceptor.  Its only job is to stop the chain (and call input on
everything) when validation errors occur.  I removed it entirely and
everything is working as we need it to.  This worked for us because,
regardless of errors, we need our entire chain to go to completion.

I could have used the excludeMethods parameter, but it would have been * .
(so it was better to remove it entirely)

Thanks for the help,

Re: when will struts 2.1 be released?

[roointan]

I wonder why it is version 2.1
virtually everything is different in 2.1.
if you ask me, I say 2.0x is so buggy, or better said, it's beta!
they should have either not released 2.0x and kept it beta for enough time,
or should have changed the new one to 3 :)

RE: [S2] Interceptor question

[Kawczynski, David]

I'm sorry, I should have been more specific with my original question.

I need to secure struts *.action URIs.  Nothing else, be it by port, 
directory mapping, or context name.  Right now.  You see, my app 
supports 
adding users and changing their roles via web UI (hence the DB). It
also supports adding sections and/or pages at run-time, which requires
the capability to dynamically add new URI-role mappings.

For these reasons, container-managed security is out of the question.  
Recompiling, redeploying, and/or restarting are best avoided.  
This is what the current framework affords me.

These are the reasons I was thinking app-managed security.  The current
framework uses a filter to do authentication & authorization validation.
It throws typed exceptions which are handled via web.xml's error-page.
I was having difficulty maintaining sessions during this error page 
redirection, which makes it difficult to maintain the 
originally-requested URL for redirection to upon successful login.  
Aside from that it works well.

But I want to expand my skillset, so I can take this opportunity to work
with Interceptors.  Or Spring.  Or something else, but these two seem to
have more traction than anything else so that's probably where I'll
land.

I'm running two almost completely unchanged applications in production that 
went from 2.0.9 to 2.1, so I guess there are more similarities than you'd

Re: Struts 2: How can we save the parameters if we do redirect and not redirect-action

   OK, I changed my view, i would go ahead and extend ServletRedirectResult
and try to include the request parameters just like how
ServletActionRedirectResult and URL component try to do. That way it would
be consistent. Your solution is also good though, but I dont like to have
extra code in my action since it will complicate my logic.

There's no extra code in the action. The code is in the interceptor. The action 
(I'm assuming) implements a marker interface to inform the interceptor that it 
should put the request parameters into the session.

IMO doing this in a custom result is the wrong way to go about it, for several 
reasons; one is that the interceptor approach works no matter what result type 
you end up using.

Performance and High CPU utilization

[sajanv007]

There is huge performance issue and CPU hogging with Struts2 tag , this was
observed while rendering JSP. These are some performance results obtained

Strut 2 Tag - With all performance tuning applied as per Struts 2
documentation - Freemarker caching etc...
Load Runner Tool
40 users
900 hits per second
10 transaction per second

Results
CPU utilization 90%
Response 3.5 sec

Replaced some of Struts2 Tag , with Custom JSP Tags like (s:label,
s:text,s:textfield,s:hidden,s:param)
40 users
900 hits per second
15 transaction per second

Results
CPU utilization 70%
Response 2.0 sec

Some where down the line Struts 2 tag are very cpu hungry , to people to
adopt to strut2 framework cpu utilization should be optimized .


Did anybody come across on how to over come this problem

S2 - Need advice with Localization

[bob fuller]

I am trying to Localize a dynamic message and would like some advice as to how 
I should go about it. My main goal is to keep the message itself as 'intact' as 
possible in my package.properties, doing this will (hopefully) speed up 
translation by an interpreter. Goals after that are to use the Struts 2 
software correctly and cleanly and also keep the amount of work needed to a 
minimum.

Here's the dynamic message that I want to localize...

Welcome to SEA (Seattle International Airport) - Additional information about 
Hotels, Entertainment, Transportation, and Dining is available.

The "SEA" & "Seattle International Airport" parts of the message are dynamic. 
Also, the following words are dynamic links - "Hotels", "Entertainment", 
"Transportation", "Dining". Here is what the message looks like in my 
package.properties file...

welcomeMessage=Welcome to {0} ({1}) - Additional information about 
{2}Hotels{3}, {4}Entertainment{5}, {6}Transportation{7}, and {8}Dining{9} is 
available.

In my JSP I do this to render the single line of text (I didn't verify that 
it's syntax correct)... 

http://www.somewebsite.com/hotels.do";>
http://www.somewebsite.com/entertainment.do";>
http://www.somewebsite.com/transportation.do";>
http://www.somewebsite.com/dining.do";>  
">  ">  ">  
">


OK. Thanks for getting this far! I am concerned about the amount of JSP that is 
needed for my single dynamic message. Is that just how it is? Or perhaps my 
approach is flawed? Does anyone have any advice or perhaps a tutorial 
suggestion that provides examples 'advanced' localization examples?

Thanks.

Re: Performance and High CPU utilization

[sajanv007]

I have tried all the tuning parameters mentioned in the link somehow CPU
utilization is always 80% ,I observed that it takes tags are rendered from
free marker cache but still the cpu 80-90% .

The first thing I'd try is removing the () in the "method" attribute.

On what plaform and JVM? How many tags are on your page? I've not seen my CPU 
usage anywhere near that high.

What kind of server are you using here, how much memory, what CPU -- when we
are getting to CPU utilization, all of these issues are relevant.

Re: Performance and High CPU utilization

[sajanv007]

 It is a solaris box and has 16 GB memory and 4 CPU it is high end server
class machine . Some how I suspect it is the OGNL or Freemarker rendering
issue .

Re: S2 - Need advice with Localization

[Paweł Wielgus]

Hi Bob,
i would do it like that:

welcomeMessage=Welcome to {0} - Additional information about {1} is available.

then in jsp


and in action
public String getWelcomeMessage() {
 return getText("welcomeMessage", varFromDatabase1, varFromDatabase2);
}

I asume that name and second parameter are constructed somehow
(database or configuration).
I'm not saying that this is most proper, but it will do the job.

Best greetings,
Paweł Wielgus.

Replace your freemarker lib with 2.3.13 or later. Prior releases had a 
concurrency performance issue.

Perhaps, but if so, I'll stick with my old dev box with a P4 and 2G running 
WebSphere, because I don't see anything remotely approaching that kind of 
usage. Or the T2000's used at my last job.

Same question, preferably with more info this time: what JVM, how many tags, 
etc.

You may want to take this up with FreeMarker and/or whoever does your JVM. 
FreeMarker/OGNL is slow, but it's not *that* slow that it'd take up 90% CPU 
like that.

I'd definitely try Al's advice as a first attempt, then.

If that doesn't mitigate the problem I'd bust out a profiler.

Re: struts2-dojo-plugin problem

Any idea how to get the struts2-dojo-plugin-2.1.2 with struts 2.0.11?  I've
tried to put the  before the  in the

idiot.  Thanks for any help you can give.

ERROR:

*, *, *, *)


I doubt this will work. Struts 2.0.11 includes a bundled version of 
Dojo, as well as the Ajax theme/tags. The Dojo plugin is intended for 
use with Struts 2.1.x, which *doesn't* bundle those items. By adding the 
plugin to a 2.0.x app, you will likely end up with conflicts.


Why are you trying to do this?

Re: [S2] not including null-params in URL of GET-submitted form

[Laurie Harper]

Pierre Thibaudeau wrote:

Is there a way to avoid null-valued (or empty-valued) parameters to be
explicitely mentioned in the URL generated by a form submitted through the
GET method?

For instance, here's a form:







If the user types "FOO" in the first textfield and nothing in the second,
the submitted URL will be something like:
http://myhost.com/myAction.action?param1=FOO¶m2=

Can I get rid of the "param2=" part, which serves no purpose?

(The alternative would be to POST the method to an action that would merely
redirect to the desired action, dropping the undesired parameters along the
way.)


This is expected behabiour; short of doing some JavaScript-fu on form 
submit, I don't think you can avoid the empty params. That said, if the 
form submit is going to cause any data updates on the server, it really 
should be a POST anyway -- and if not, I'm not sure why the 'noise' in 
the URL matters.

Re: S2 - Need advice with Localization

[Laurie Harper]

bob fuller wrote:


I am trying to Localize a dynamic message and would like some advice as to how 
I should go about it. My main goal is to keep the message itself as 'intact' as 
possible in my package.properties, doing this will (hopefully) speed up 
translation by an interpreter. Goals after that are to use the Struts 2 
software correctly and cleanly and also keep the amount of work needed to a 
minimum.

Here's the dynamic message that I want to localize...

Welcome to SEA (Seattle International Airport) - Additional information about 
Hotels, Entertainment, Transportation, and Dining is available.

The "SEA" & "Seattle International Airport" parts of the message are dynamic. Also, the following words are dynamic 
links - "Hotels", "Entertainment", "Transportation", "Dining". Here is what the message looks like in 
my package.properties file...

welcomeMessage=Welcome to {0} ({1}) - Additional information about 
{2}Hotels{3}, {4}Entertainment{5}, {6}Transportation{7}, and {8}Dining{9} is 
available.

In my JSP I do this to render the single line of text (I didn't verify that it's syntax correct)... 


http://www.somewebsite.com/hotels.do";>http://www.somewebsite.com/entertainment.do";>http://www.somewebsite.com/transportation.do";>http://www.somewebsite.com/dining.do";>  ">  ">  
value="%{urlTransportation}"/>">  ">


OK. Thanks for getting this far! I am concerned about the amount of JSP that is 
needed for my single dynamic message. Is that just how it is? Or perhaps my 
approach is flawed? Does anyone have any advice or perhaps a tutorial 
suggestion that provides examples 'advanced' localization examples?


There are some obvious clean-ups you could do, such as: not requiring a 
separate s:param for the 'a' start-tag and end-tag (which seems error 
prone); factoring out the URL construction logic so you don't have to 
repeat the airportCode bit for each one; etc. That said, I would suggest 
considering a different approach.


1) create a custom tag / .tag file / custom struts tag to fully 
encapsulate all that presentation logic, perhaps using a single 
key/identifier to resolve all the dynamic bits;


2) creating a POJO helper class that knows how to do the dynamic data 
lookup and complex message construction, exposing an instance of it via 
a getter in your action and keeping the JSP code as simple as 



You didn't say *how* the various parts of the message are dynamic 
(loaded from a resource bundle? loaded from a database? hard-coded with 
different values in different JSPs?), so it's hard to be any more 
specific than that. And I'm sure there are other possible approaches I 
haven't thought of ;-)

Hello Struts-Freaks,

I have a quite easy question, I think:

how can I configure an action in struts.xml, that does nothing than go 
to the page I came from ?

Something like  or so ?

Thanks in advance.

Re: Configure result to go back to page I came from....

[Volker Karlmeier]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hi,

I think I have to explain my problem more clearly:

I have a page that show some text-fields. These Text-Fields can be 
filled in different languages.
To choose the according language, you can click on a button (e.g. 
english/french etc.) and a method "switchlanguage" is called,

which sets a parameter to the language I want to enter.
As I need this function on various pages, I want to implement it in a 
superclass of my action class.
After clicking on a language-button, I need to set the language and go 
back to the form to enter the text.
Therefore, I need a way to react on a result called "languageSwitched" 
which leads to the page I just came from.
As I do not want to write it in every action but only once in 
struts.xml, I need a result that goes back to that page

without having to specify each time, which page that was.
Is that possible ?

~  Volker

[S2] s:form and title internationalization

[Paweł Wielgus]

Hi all,
i would like to add internationalized title element to my form,
but  is not working - title is not evaluated.
Does anyone have some kind of an elegant solution for it?
Or maybe i'm mising something here?

Best greetings,
Paweł Wielgus.

The form element doesn't render a title. It's an attribute of the form element 
because it inherits an underlying class covering the HTML tags, but doesn't use 
it itself.

There are a number of possible solutions, but the easiest would be to just add 
a table row/cell and use

Good morning.

I want to make the following order:

" />

With this order pretend that the value of attribute value of the first tag
 is dynamic but gives an error.
Does anyone know how I get that?

Re: struts2-dojo-plugin problem

[daveck]

I though the examples at
http://struts.apache.org/2.0.11.2/docs/ajax-and-javascript-recipes.html
would be helpful and didn't want to use all of struts 2.1 until the final
release.  I'm pretty sure I read somewhere that it was being done...

Re: Performance and High CPU utilization

[Andrea Vettori]

Don't now if this is current because I'm using an old struts2 release  
but this has helped a lot reducing my cpu & memory usage :



freemarker.template.Configuration fmc =  
(freemarker 
.template 
.Configuration 
)ServletActionContext 
.getServletContext 
().getAttribute(FreemarkerManager.CONFIG_SERVLET_CONTEXT_KEY);

if (fmc != null) {
 
((freemarker 
.ext.beans.BeansWrapper)fmc.getObjectWrapper()).setUseCache(true);

}

There is huge performance issue and CPU hogging with Struts2 tag ,  
this was
observed while rendering JSP. These are some performance results  
obtained


Strut 2 Tag - With all performance tuning applied as per Struts 2
documentation - Freemarker caching etc...
Load Runner Tool
40 users
900 hits per second
10 transaction per second

Results
CPU utilization 90%
Response 3.5 sec

Replaced some of Struts2 Tag , with Custom JSP Tags like (s:label,
s:text,s:textfield,s:hidden,s:param)
40 users
900 hits per second
15 transaction per second

Results
CPU utilization 70%
Response 2.0 sec

Some where down the line Struts 2 tag are very cpu hungry , to  
people to

adopt to strut2 framework cpu utilization should be optimized .

Hi Joe,

thats a good solution but only works partially for me.
The new Language is set correctly, but as no request is submitted, my 
textfields and textarea-fields are not updated

so that I cannot see the content for the language I have chosen.
Do you you a solution for that ?

Regards

~  Volker

| Hi,
|
| I think I have to explain my problem more clearly:
|
| I have a page that show some text-fields. These Text-Fields
| can be filled in different languages.
| To choose the according language, you can click on a button (e.g.
| english/french etc.) and a method "switchlanguage" is called,
| which sets a parameter to the language I want to enter.
| As I need this function on various pages, I want to implement
| it in a superclass of my action class.
| After clicking on a language-button, I need to set the
| language and go back to the form to enter the text.
| Therefore, I need a way to react on a result called
| "languageSwitched"
| which leads to the page I just came from.
| As I do not want to write it in every action but only once in
| struts.xml, I need a result that goes back to that page
| without having to specify each time, which page that was.
| Is that possible ?
|

| | Something like  or so ?
| |
