File upload using DynaActionForm/SynaValidatorForm
Struts 1.2 I need to try to get file upload to work for an existing struts app. I was reading through the following: http://wiki.apache.org/struts/StrutsFileUpload where it mentions the following for Dyna action forms: form-bean name=myForm type=org.apache.struts.action.DynaActionForm form-property name=myFile type=org.apache.struts.upload.FormFile/ /form-bean So - based on this - I ended up with the following for a DynaValidatorForm: form-bean name=uploadFile type=org.apache.struts.validator.DynaValidatorForm form-property name=title type=java.lang.String/ form-property name=revdate type=java.lang.String/ form-property name=revinfo type=java.lang.String/ form-property name=documentfile type=org.apache.struts.upload.FormFile/ /form-bean However - when the form POSTs to this action - I get the following in the log: 2006-11-28 09:35:52,986 ERROR [org.apache.struts.util.RequestUtils] Error creating form bean of class org.apache.struts.validator.DynaValidatorForm java.lang.NullPointerException: The type for property documentfile is invalid at org.apache.struts.action.DynaActionForm.set(DynaActionForm.java:415) at org.apache.struts.action.DynaActionFormClass.newInstance(DynaActionFormClass.java:184) at org.apache.struts.config.FormBeanConfig.createActionForm(FormBeanConfig.java:212) at org.apache.struts.util.RequestUtils.createActionForm(RequestUtils.java:294) at org.apache.struts.util.RequestUtils.createActionForm(RequestUtils.java:193) at org.apache.struts.action.RequestProcessor.processActionForm(RequestProcessor.java:321) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:204) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1164) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:415) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) Does the DynaValidatorForm support FormFile?

Tiles standalone (without struts)
Hello, I want to integrate Tiles to my project without Struts. I have my own front controller implementation. Actually, the tiles packaged with struts 1.3.5 cannot be used in standalone mode, the TilesServlet doesn't exist. But, i read on this mailing list, that a new subproject is on the way : Tiles 2.0.

Now, since it's quite remote that such a drastic bug exists in WW 2.2.4, I'm starting to think that maybe the behavior I expect is not the correct one. Now, could someone please clarify whether the following is true? 1- When parameters are available in the query string, those parameters are made available to the action through ActionContext.getContext().getParameters(). Is this true? 2- If a property on the action has the same name as one of those parameters then the framework will attempt to set the property with the parameter's name. This is not what is currently happening. Since WW 2.2.4 is supposed to be production quality then I'm guessing that there must be something wrong with the configuration. It can not be that some configuration I've provided is wrong, simply because I have not provided any. It could be, though, that some configuration is missing.

The documentation for this form suggests that the only difference is that DynaValidatorActionForm uses a separate XML file to define field validation rules. I'm not sure how that's different than using commons-validator, though... I think the problem is more likely that org.apache.struts.upload.FormFile is not a class -- it's an interface. Struts can't create a new object because Java can't create a new instance of an interface. The HOWTO Chris mentions instructs you to add this to your controller configuration: multipartClass - The fully qualified Java class name of the multipart request handler class to be used with this module. Defaults is org.apache.struts.upload.CommonsMultipartRequestHandler. Have you configured your controller element in this way? It appears that there is a default, but that could be part of the problem.

An Example or a sample code will be great. Do you just want to call Perl on the command line, or do you have some kind of perl-cgi thing that you need to interact with? Also is it possible to send input parameters to the script? That depends on how you want to invoke Perl. If you are using a URL to call-back to your web server in order to invoke Perl on your behalf (using CGI), then no, you can't send command-line parameters to Perl... you'll have to use CGI for that. On the other hand, if you're going to be calling Perl directly, then you can certainly use command-line parameters. I'm sure there are HOWTOs out there for how to do this kind of thing, but you want to start by looking at the java.lang.Runtime class's exec() methods. There are a bunch, depending on what information you want to pass. Choose carefully. The following considerations are extremely important: 1. Using Runtime.exec() allows users of your webapp to start new processes on your server. Are you really sure you want this to happen? Imagine if all of your users hit your Perl-invoking action at once. Would it kill your server? 2. You can't trust any information passed-in through request parameters. If you want to use command-line parameters, make sure that you taint check them so that someone doesn't add ; rm -rf / to the end of your command and end up destroying your filesystem. 3. Always remember to handle the resulting Process object (returned from Runtime.exec) properly. For instance, if you don't get the input and error streams from your spawned-process and read from them, they may never complete and never fail. Always read error and input until they are closed. If you are not providing input (via stdin, using an OutputStream from Java) to your process, then consider closing the OutputStream so that your process won't (accidentally) wait around for data on stdin. 4. Unless you really know what you are doing, always call Process.waitFor() to make sure that the process has terminated. You don't want a ton of processes starting and never finishing, without you knowing about it. At least if your Perl processes are never finishing, you'll know it because you'll get problems in your webapp, too. Lastly, what are you doing with Perl? Can the same thing be done within Java? That would be ideal, since spawning processes from a webapp is a dangerous business. Alternatively, could you put information in a database describing what needs to be done, and run Perl in a batch-oriented way -- like using a cron job to periodically do these operations? I think you'll end up with a more stable webapp that way.

Re: [S2] configuring Tiles with Struts 2
Very odd, the 2.0.1 tag (http://svn.apache.org/repos/asf/struts/struts2/tags/STRUTS_2_0_1/plugins/tiles/) has no reference to the TilesContainer, and I thought it was released/tagged before it was introduced.

radio buttons within a nested form based on a db table.
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 OK... I've outsmarted myself and I'm looking for a way out of the corner I painted myself into.. Here's the deal: I have a radio button (group?) that I want to build dynamically based on the contents of a database table. This radio button set will then set a parameter within a nested form. The solution I came up with at first was to create a Hibernate service that builds the requisite HTML from a query putting in values and labels as appropriate. Fine... this was OK as long as I didn't have to make a second trip through the form. But I do... When the second trip happens the radio button forgets what the user set it to and they have to set it again. Nobody has to explain it to me.. I fully understand what booby trap I stepped on. Moving on... what methodology would folks suggest for dynamically building the radio button group in this instance? - -- Peter L.

Themes and templates
Hi to all, im building an struts2 based application and i dont understan the concept of themes an templates. In the past i used struts 1, and in the view i used jsp tags and struts tags like iterate and others. Now in the application that im buildin i use tags provided by struts like s:action s:include s:iterator, s:form etc. the problem started when i was using the radio button tag that renders radio buttons based on a list. The buttons are put side by side... and i want to put one below the other label radio1 label radio2 (now) label radio1 label radio2 (mi needs) I want to know if render of buttons tables forms and other tags are based on this templates..and how i could change it Regards Juan
Re: Themes and templates
If you set struts.ui.theme=simple in the struts.properties file you won't fight with the templates and it will be sort of like good old struts 1. However, there are other gotchas in store. You have to get validation errors on the screen yourself using s:fielderror/ since the theme cleverly puts the validation errors next to the invalid fields but not with simple. This is how I have done it but there is probably a better way: s:if test=hasErrors() h3span style=color:red; font-weight:boldValidation Error/span/h3 s:actionerror/ s:fielderror/ /s:if The hasErrors() comes from the value stack from you action that extended ActionSupport. But this didn't really answer your question of how to make themes and templates work for you :(.

RE: radio buttons within a nested form based on a db table.
If you're already building the HTML yourself why can't you just build it using the current values and set the appropriate radiobutton(s)? From: Peter L.

Struts, AJAX, JSP, and JavaScript question
I have a JSP and there's a link in the rendered page that makes an AJAX call (to a Struts action) when clicked. The results of that action, and the contents of the response are set as the innerHTML on a hidden div defined inside the afore mentioned rendered page. The div is then un-hid. Everything is working correctly except for one part: When the div is displayed, the JavaScript code in the contents returned by the AJAX call isn't being executed and thus, the contents of the div aren't set up correctly. Does anyone know a way to have the JavaScript be executed? Or force the browser to execute it? I used to have an iframe and everything worked great, but there was a bad side effect with session timeouts and so we've decided to not use them. Any help would be appreciated. Thanks. -Adam
Re: Struts, AJAX, JSP, and JavaScript question
In struts 2 we already do that for you(link tag and button tag in the
ajax theme), this is the code to extract the javascript sections(from Dojo):
parse : function(s) {
this.log(Parsing: + s);
var match = [];
var tmp = [];
var scripts = [];
while(match){
match = s.match(/script([^]*)([\s\S]*?)\/script/i);
if(!match){ break; }
if(match[1]){
attr = match[1].match(/src=([']?)([^']*)\1/i);
if(attr){
// remove a dojo.js or dojo.js.uncompressed.js from remoteScripts
// we declare all files with dojo.js as bad, regardless of folder
var tmp2 = attr[2].search(/.*(\bdojo\b(?:\.uncompressed)?\.js)$/);
if(tmp2 -1){
this.log(Security note! inhibit:+attr[2]+ from beeing
loaded again.);
}
}
}
if(match[2]){
// strip out all djConfig variables from script tags nodeValue
// this is ABSOLUTLY needed as reinitialize djConfig after dojo
is initialised
// makes a dissaster greater than Titanic, update remove
writeIncludes() to
var sc = match[2].replace(/(?:var
)?\bdjConfig\b(?:[\s]*=[\s]*\{[^}]+\}|\.[\w]*[\s]*=[\s]*[^;\n]*)?;?|dojo\.hostenv\.writeIncludes\(\s*\);?/g,
);
if(!sc){ continue; }
// cut out all dojo.require (...) calls, if we have execute
// scripts false widgets dont get there require calls
// does suck out possible widgetpackage registration as well
tmp = [];
while(tmp){
tmp =
sc.match(/dojo\.(?:(?:require(?:After)?(?:If)?)|(?:widget\.(?:manager\.)?registerWidgetPackage)|(?:(?:hostenv\.)?setModulePrefix))\(([']).*?\1\)\s*;?/);
if(!tmp){ break;}
sc = sc.replace(tmp[0], );
}
scripts.push(sc);
}
s = s.replace(/script[^]*[\s\S]*?\/script/i, );
}
return {
text: s,
scripts: scripts
};
}
and to execute it:
var parsed = this.parse(data);
//eval scripts
if(parsed.scripts parsed.scripts.length 0) {
var scripts = ;
for(var i = 0; i parsed.scripts.length; i++){
scripts += parsed.scripts[i];
}
(new Function('_container_', scripts+'; return this;'))(this);
}
where 'data' is the html returned from the action.
have fun :)

I want to know if render of buttons tables forms and other tags are based on

Hi Juan,
The rendering of the buttons is based on the theme template. The templates
can be found in the Struts source in:
/core/src/main/resources/template
There are a few directories there. I believe S2 defaults to the xhtml theme.
I have extended the xhtml theme extensively to do variable multi-column
layouts. It took some work, and at the time I thought it was hard, but in
retrospect it wasn't that bad.
Take a look at the template that backs s:textfield first. It's text.ftl in
the xhtml directory. It's real short:
#include /${parameters.templateDir}/${parameters.theme}/controlheader.ftl
/
#include /${parameters.templateDir}/simple/text.ftl /
#include /${parameters.templateDir}/xhtml/controlfooter.ftl /
It includes a controlheader, the simple text.ftl template, then a
controlfooter.
The control header and footer is where the table wrapping happens and the
simple/text.ftl is where the actual input element is generated from.
Just go through it a piece at a time.
I have yet to use a radio button group, but I think the template to start
with is radiomap.ftl.
When going through this just remember to follow the includes.
Good luck,
Mark

In WEB-INF/classes/ make a template directory. 2. Copy the xhtml, and simple directories from the Struts distribution to that directory. 3. in WEB-INF/classes/template make a directory for your own theme, such as WEB-INF/class/template/mytheme/. You'll put any template you want to override in this directory. 4. Optionally, although I'd highly recommend it, copy the contents of the xhtml theme to your theme directory so you have something to hack on. 5. Hack away and see how it works.

Re: Struts, AJAX, JSP, and JavaScript question
Hi Adam, If your doing straight AJAX yourself, i.e., directly interacting with the XMLHttpRequest object, this won't execute script for you automatically. In fact, it won't do much of anything for you automatially, aside from parsing XML if that's your return type. Otherwise, it's just text to the object and you'll have to execute scripts yourself. Another poster gave you some info if your using S2, but I'm guessing by your description your using S1. In that case, continue reading! :) The AjaxParts Taglib (APT) in Java Web Parts (JWP) takes care of this for you... you can certainly switch over to using APT, but if you just want some code to execute scripts, take a look here: http://javawebparts.cvs.sourceforge.net/javawebparts/javawebparts/WEB-INF/src/javawebparts/ajaxparts/taglib/resources/AjaxPartsTaglib.js?view=markup Down around line 313 you'll find the execScripts() function... simply yank that out and use it on the responseText from XMLHttpRequest and you'll be good to go.

Does Struts 2 solve the action chaining problem?
Hi, One of the problems with Struts was that if you had a page that requires some setup and this page submits to an Action, then you would not be able to set validate to true on that action because if validation problems occur then Struts will take you directly to the input JSP without performing the setup and your JSP wouldn't work. A solution to that would be to specify the input of the action as the setup action, which means you're doing action chaining and Struts is not good at that (it will reset your form among other things). The solution of choice for us so far was to call validate() ourselves in the action and if a validation problem occurs then we call the setup method (eventually you start using your action methods as an API which still was not good). Another problematic scenario is the case when you're editing some database record for example. When you go to your setup action for the first time, you will populate drop down lists for example, and then load the existing values from the database to your JSP fields. If the user attempts to save and some problem occurs then in the setup action, you will need to again populate the drop down lists, but you will NOT want to overwrite the user's inputs with the existing data. This is very similar to the first problem, but you would also need to pass some flag to the setup method to tell it whether to copy the data from the database to your ActionForm. Does Struts 2 or even WW 2.2.4 solve that problem in an elegant way? I remember coming across something about using Interceptors for that, but that would mean creating an Interceptor for almost every action of that type. I also noticed that there are some warnings in the documentation against using action chaining in Struts 2 as well.

Re: Struts, AJAX, JSP, and JavaScript question
That will only work if the response is nothing but JavaScript, in which
case your 100% correct (although many people say that eval() should be
renamed evil() and should be avoided like the plague... I'm not *quite*
that extreme in my avoidance of it).
As a quick proof:
html
head
script
var s = ;
//s += + html + ;
//s += + head + ;
//s += + script + ;
s += alert('test');;
//s += + /script + ;
//s += + /head + ;
//s += + body + ;
//s += Hello;
//s += + /body + ;
//s += + /html + ;
function testit() {
eval(s);
}
/script
/head
body
The Body
input type=button value=testit onclick=testit();
/body
/html
Load this file in your browser and you'll find that you get an alert, as
expected... now, uncomment the commented lines and reload and you'll see
that it no longer pops the alert (interestingly, in IE I get a syntax
error, because it's trying to interpret the markup as script, but in FF
it just quietly doesn't work, not even a notice in Firebug).
So, if the idea is to execute script blocks that are part of an HTML
response, a simple eval() won't work... but if all your returning is
script, then I definitely echo Chris' suggestion and would go with
eval() (regardless of who wants to slap your hand with a ruler).

Hi Adam,
If your doing straight AJAX yourself, i.e., directly interacting with the
XMLHttpRequest object, this won't execute script for you automatically.
In fact, it won't do much of anything for you automatially, aside from
parsing XML if that's your return type. Otherwise, it's just text to the
object and you'll have to execute scripts yourself.

Internationalized messages for pure JavaScript client side validations
Hi,
I read the following in the documentation
quote
Errors are reported using the default validation message, not the
internationalized version that the server-side might be aware of. This
is a known issue. You may want to try the AJAX Client Side Validation
for messages that are fully internationalized.
/quote
Is this feature impossible to implement using the current framework? I
don't want to go to the server for simple client side validations and
the internationalized messages are a must for me.
I looked at the code and it seems that this expression is the one that
yields the message
${validator.getMessage(action)?js_string}
I'm not into freemarker but it seems to be calling something on the
validator object. Is there a way we can enhance the validation object in
some way so that it exposes the internationalized message or is this
object not aware of the user's current locale at all? Could it be
enhanced so that it is aware of it?
Thanks,
Tarek Nabil

How Where to specify the Request Processor class name?
Hi Guys, I have read in the documentation and on the net also about the Struts framework. There would be only one ActionServlet per web app and one RequestProcessor per module. Is that true? Any body pls help me with your answers and any useful sites. I believe we can over write the ActionServlet, this case we would mention the Servlet class in the web.xml. But I read that even RequestProcessor also can be over written, but not mentioned where to specify the implemented RequestProcessor class name. I really need some useful info on this topic.

Interceptors are an O-O oriented approach to this kind of issue, but there are ligther weight alternatives. For the particular need of a setup action, consider the use of the Preparable interface in Struts 2. It's pretty similar to what the Tiles Controller interface supported in Struts 1.x ... a chance for your business logic to set up the stuff that is needed for rendering a particular view. If you're looking at JSF as a view technology, you'll likely be interested in what Shale http://shale.apache.org/; has to offer, particularly in the View Controller feature. Not only does the View Controller functionality support the setup scenario (via the prerender() callback method on the ViewController interface), it also supports cleaning up *after* the view has been rendered, via the destroy() callback.

s2 image submit button and methods
Hi, yesterday it took me a day to understand and resolve a problem so I think it can be useful to share it; maybe someone can explain a better solution. I have a form with more than one submit button. The submit buttons are images so I used the s:submit type=image method= ... tag on all but the default button. The problem is that since the image button is considered by the browser similar to an imagemap, if the button is called btnA, the browser submits btnA, btnA.x and btnA.y request parameters, where the .x and .y are the coordinates of the click inside the image. I think this cannot be disabled on the browser since it is required by the HTML specifications. Now this cause problems when the parameters are used by the action to call the appropriate method. If I have a button like s:form action=anAction ... s:submit type=image method=aMethod ... in the HTML you get something like input type=image name=method:aMethod ... and when the request is submitted the browser sends method:aMethod, method:aMethod.x and method:aMethod.y parameters. This cause the framework to try to execute the aMethod.x() method on the action class which generate an Exception !!! I've tried to filter the parameters with ParameterNameAware but the parameter that starts with method: are not passed to the acceptableParameter method. So I extended the parameters interceptor and overrided the acceptableParameter function and even if now I see the parameters on the method, even if I reject them, the framework use them to try to execute the method in the action. The solution I used is to have the image submit to set a value (like s:submit type=image name=aName value=aValue and use that value inside the execute method of the action to call the appropriate method. But I'm looking for a better solution. I also think that since this will be a common problem, it should be addressed by the framework automatically rejecting method:xxx and action:xxx parameters that ends with a .x and .y. Thanks -- Ing.
