Re: [S2] Exploding memory usage with JBoss5
Just to give some more information (maybe someone with more in-depth knowledge finds the time to take a look at this issue): I have an EAR file with two EJB3 entity beans and a web client WAR. It can be found here: http://www.informatik.fh-wiesbaden.de/~knauf/KomponentenArchitekturen2008/kuchenzutatstruts/KuchenZutatStruts.ear On copying it to the deploy directory of JBoss, memory usage increases by 20 MB. On calling the first struts page (http://localhost:8080/KuchenZutatStrutsWeb/ - then click the link on the index page), memory usage increases by another 30 MB. This happens with every redeploy, at least during normal developing/testing cycles, which means one redeploy every few minutes. If I wait on longer period until the next redeploy, memory usage might decrease again. But after 5-10 redeploys without longer pauses between (which is normal when trying to find/fix bugs), the machine is constantly swapping, and the app is poorly slow. I suspect a JBoss 5 problem, but as I have only very basic struts knowledge, I don't know enough about the internals to file a struts or jboss JIRA. Thanks Wolfgang Knauf Wolfgang Knauf wrote: Hi all, I have a quite small Struts 2 application running on a JBoss 5.0GA. It contains some EJB3 entity beans, an EJB3 session bean, a handful of struts actions and three JSPs. After about 5 redeploys (I use JSR88), JBoss is consuming more and more memory (500MB) and thus getting poorly slow. The system is Windows XP64, JDK 1.6, deployment from Eclipse 3.4/WTP 3.0.

Re: Upgrading Struts 2
Hi, We've migrated an app from 2.0.11 to 2.1.2 (and then to 2.1.6 when it became GA - this was a trivial upgrade). I found this article on the Apache wiki very useful: http://cwiki.apache.org/S2WIKI/troubleshooting-guide-migrating-from-struts-20x-to-21x.html I had no major issues - and the performance of app 'seemed' a bit quicker (I've done no definitive tests, but the 'feel' was of snappier rendering). The only problem I ran into was where I had some nasty hack for passing dynamic parameters to an action through redirect- action - I was doing it in a non-standard way, which worked in 2.0.11. It was a quick fix to change it to the proper way to do it. Andy.

Re: [S2] Exploding memory usage with JBoss5

On calling the first struts page (http://localhost:8080/KuchenZutatStrutsWeb/ - then click the link on the index page), memory usage increases by another 30 MB. I have the same app in a JSF version (same ejb layer, but different web client), and there I did not have memory problems. So I would remove the ejb layer from the suspects list ;-). With a plain WAR file, memory usage increases by 20MB on deploy, but only by 5 on calling the first page. So the maximum is not reached as quick as with the EAR file. But the same tendency can be seen: memory increases on each redeploy, and sometimes goes down, but mostly it is growing.

The reasoning behind wanting to do this is my users are somewhat curious, and are prone to poking. I'd prefer for them to not see blank pages, stack traces, or otherwise!

how to redirect from prepare() method in struts 2
Hello friends,
I have very little experience in struts 2 I have this typical requirement
where I feel that I have to redirect form the prepare() method when the user
is not logged in (by checking whether some session entries present or not).
Actually I am trying to avoid repetitive session checking redirecting at
the beginning of every action method, for example
public String listUsers() throes Exception
{
//if (session.get(userType) != null
session.get(userType).equals(admin))
//then show the result
//otherwise redirect to the login page
}
public String viewDetails() throes Exception
{
//again code for the same checking
}
so I thought that since the prepare() method is being called every time some
action is being mapped to a method in this class so why not put the code for
checking redirecting inside of prepare
like,
public void prepare() throws Exception
{
//if the user is not logged in
//redirect to the login page
}
But the problem is that I cannot return any string (which I can specify as
result of type redirect-action in the struts.xml file)since this function
has return type void also I could not find any method to redirect forcibly.
So, my question is whether it is possible to redirect form any method which
has not been mapped as an action at all?
if it can be done then how to do it?
Any ideas regarding this problem would really help.
Thanks in advance

It would be much cleaner to put that kind of logic into an interceptor
rather than in a prepare() method. It would cut down significantly on
code duplication.

ActionMapper doesn't add Parameter
the objectiv is to be able to have url like .../public/123.mp3 so this
customized ActionMapper was written.
public class MyActionMapper extends DefaultActionMapper {
static ActionMapper fallback = new DefaultActionMapper();
private static String getSongIdFromUrl(String s, String regex){
Matcher m = Pattern.compile(regex).matcher(s);
return m.find() ? m.group(1) : null;
}
@Override
public ActionMapping getMapping(HttpServletRequest request,
ConfigurationManager configManager) {
String uri = getUri(request);
String regex = /public/(\\d+).mp3;
String id = getSongIdFromUrl(uri, regex);
if(id!=null){
ActionMapping m = new ActionMapping();
m.setExtension();
m.setMethod(download);
m.setNamespace(/public);
m.setName(fileDownload);
Map params = new TreeMap();
params.put(id, id);
m.setParams(params);
return m;
}
return fallback.getMapping(request, configManager);
}
}
the problem is, that the id-Attribute altough correctly extracted from the
url dosn't become part of the parameter-list. The url
.../public/123.mp3?id=123 works by the way but is of course redundant. Why
doesn't
params.put(id, id);
m.setParams(params);
work?

Which version of struts are you using? There was a bug at some point where
getModel() was called more than once, something like the following -
if (getModel() != null) {
model = getModel();
}
This came up a few times and prior to the fix, the workaround was to
instantiate the model in a prepare() method.

Re: Only call actions from certain forms
Actually, having an interceptor makes some sense in this case. How can interceptors short circuit the stack and action to return a result code? The ideal situation here would be that the protector interceptor is above the validation interceptor, checks for the form token, and chucks an error result code, protecting the validators from null parameters and so on. I can't see anything in the documentation about achieving this - the ActionInvocation javadoc suggests that ActionInvocation.setResultCode() will not short-circuit the stack, and that the action's own result code will override the interceptor-set result.

The reasoning behind wanting to do this is my users are somewhat curious, and are prone to poking. I'd prefer for them to not see blank pages, stack traces, or otherwise! Darn users... this is a pretty typical requirement and is one of the reason workflow engines came about; they can handle simple cases like this as well as disallowing jumps into the middle of multi-step processes etc. Dave - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

Re: [S2] Store a request and invoke it later
Thank you, Dave. I think Martin misunderstood me. I was planning to store everything in the session anyway. What I would like to know is _what_ I have to store and _how_ to invoke the right action later in order to make the login stuff transparent. Maybe I am also going to check out Spring Security, as Wes suggested, but ATM I am using my own little AuthenticationInterceptor that supplies every Action (if desired) with the UserLogin-bean and redirects to the login-action if the bean is mandatory (indicated by annotation). It's working nicely, and I would like to keep it :-) Greetings, ~Andreas Dave Newton schrieb: Martin Gainty wrote: 1)store in db 2)if static.. place in properties file 3)you can use OGNL to place values into 'application' scope ... 3) Seems like 'session' would be more appropriate since we're talking about storing an individual user's request, to be re-used after a login.

Hi Andreas, Am 25.01.2009 um 02:53 schrieb Andreas Mähler: Thank you, Dave. I think Martin misunderstood me. I was planning to store everything in the session anyway. What I would like to know is _what_ I have to store and _how_ to invoke the right action later in order to make the login stuff transparent. Hint: storing *everything* into the session might be unwise in some circumstances, as all resources on a server are limited, even cheap memory. So you want a login page displayed when a user accesses a secured are an the application and show the correct page after successful authentication. There are several ways to do this with struts. I would use a simple redirect result as long as you have to deal with HTTP- GETs only, as it's pretty hard to redirect a POST. I have not tried it but should work like this: - Create a global result[1] which leads to the login page. - When your interceptor thinks a login is required, store the requested URL to the session and return the global login result from your interceptor. - When the login action ends successfully, if an URL is in the session, redirect to it using a simple redirect result with a parametrized url [2]. As for POSTs, even if I don't like it, you should be able to store action, namespace, method and the parameters of the ActionInvocation to the session and retrieve them later to invoke the action via chain result. Using chain result at all is discouraged anyway[3]. I think this is not necessary: the usual use-case here is a user has clicked on a deep-link into the application (form a bookmark, newsletter or who-knows-where) and needs to be authorized first. For his convenience we want to get him to the page he wanted directly after the login. Whether this fits for your application, I don't know.

Re: s:radio on multiple lines
What I meant before is that something like this:
s:radio name=selectedId list=myMap/
puts everything on the same line. And there is no place there to add a
br/ tag.
I found a solution in the end, after googling a bit more and with more
relevant keywords:
s:iterator value=myMap.values()
s:radio name=selectedId list=#{id: name}/br/
/s:iterator
Assuming the action exposes a map of id and some object with the [id, name]
properties. The map key id is the object id field and selectedId receives
the id of the selected object.
http://www.daniweb.com/forums/thread159633.html
http://struts.apache.org/2.x/docs/how-do-i-render-a-single-radio-button.html
I also came across a discussion in the XWork world about adding a vertical
parameter to the radio tag. That'd be a great idea. Hope we will have that
in next version of Struts2 too.

Re: Handling Browser Back/Forward Button in Struts2
Hi Hi Paweł,
i tried all the way in secure way
i implimented SSL and now my tomcat is running on port 8443 usinh https
protocol
i have created a custom interceptor for setting the header values
when user click logg off button this custom interceptor is working setting
the header values below is the code i am using
ActionContext context=invocation.getInvocationContext();
HttpServletResponse
response=(HttpServletResponse)context.get(StrutsStatics.HTTP_RESPONSE);
if(response!=null){
System.out.println(**setting
header**);
response.setHeader(Cache-Control, must-revalidate);
response.setHeader(Cache-Control, max-age=0);
response.setHeader(Pragma, no-cache);//HTTP 1.1
response.setDateHeader (Expires, 0); //prevents caching at
the proxy
response.setHeader(Cache-Control,no-store); //HTTP 1.1
}
and on my logot message i have something like this
META content=MSHTML 6.00.2900.2180 name=GENERATOR
META HTTP-EQUIV=CACHE-CONTROL CONTENT=NO-CACHE
META HTTP-EQUIV=EXPIRES CONTENT=-1
META HTTP-EQUIV=PRAGMA CONTENT=NO-CACHE
but still results are same
i can go back to secure page using browser back button
any idea why this is going on??
or do i need to set anything apart from this?
