Struts 1 log out issue
Hi,
I our project we need to put a dynamic log out link,which will come from a
properties file.
While logging out we want to invalidate the session also.
I have written a logout action class where i m invalidating and removing the
attribute from the session.
Then after success in struts-config.xml file I am redirecting to the log out
url,which is hard coded.
Does any one know how to access properties file constants into
struts-config.xml.
And should be the best way to do.
Thanks

Anyone can tell me..how to get property files attributes in
struts-config.xml file.
I want to use dynamic "path",which I will get from properties file for
logging out.
Thanks

Thanks for the response.
Is there any way struts-cofig.xml read any properties file?

There are multiple ways to do it.
one is to write a piece of code where we can use redirect dispatcher for
redirecting to the required url.
second on click of logout link take the user to a jsp where session is
invalidated , after this forward the user to the desired location.

I'm not 100% sure, but ${property-name} might work.

Posted by Ulf Liedén <ul...@gmail.com>.
Hi Celinio,
personally, I would build a method that gives back the URL of the page you
are currently visiting, including all parameters. You put this method in a
superclass of all your actions, so that its available everywhere. In the
code you decide which locale parameter to set, according to your current
locale.
The method in the action class could look something like this:
public String getLocaleSwitchURL() { String url = getContextPath() +
ServletActionContext.getActionMapping().getName() + ".action?" +
"request_locale="; if (getLocale().toString().equals("en_EN")) { url +=
"fr_FR"; flagURL = "fra.jpg"; } else { url += "en_EN"; flagURL = "eng.jpg";
} url += "&"; url += ServletActionContext.getRequest().getQueryString();
return url; } public String getFlagURL() { return getContextPath() +
"images/" + this.flagURL; }
All Strings should of course be configurable, and not hard coded like this.
But just to give you an idea how it could work. You output the link like
this:
<a href="<s:property value="localeSwitchURL" escape="false"/>">
<img src="<s:property value="flagURL" escape="false"/>" />
</a>
So if the user clicks the link, he will actually call the same page again,
with the same parameters.
Regards,
Ulf

Great remarks Denis, thanks!
Didn't know about includeParams="get"... already changed things to use
that, works great! Simple and elegant solution, I too think urls like
url/delete?id=# should be best avoided.
Using your approach (that is, closer to http specs, no deletes using GET
method), how do you do it in the case of wanting to show the user a list
of entities and direct links for deleting each one? I have my urls
exposed because I use simple url to a deleting action with an ID as a
GET param, how do you "generate" a link (or several in the same page) to
a deleting action through POST? Do you always have to use forms?
Sorry if this has gone a little bit too off-topic.

Re: [Struts 2.1.8.1] Internationalization: how to remain in the current
page ?
Posted by Denis Cabasson <de...@gmail.com>.
Hi,
We use a simple and empty <s:url includeParam="get"/> tag to loop back
to the current action/url.
The only thing you have to look for are those "unsafe" urls: we don't
have any "unsafe" urls in our application, thanks to an extensive POST
then GET approach. Whenever some action is done in the application
(through a POST), we process this action, update the relevant stuff in
the database, and issue a redirect answer to a GET url, that will
display the result of the action. That way, we can reload the current
page (be it for switching language or just a browser reload) without any
issue. This approach takes care of the bookmarking issue as well. I
think this approach way more robust that tinkering with URLs to define
safe and "unsafe" URLs.
We had to do a bit a workaround code so that on the redirect to a GET,
we don't lose all of our context. We actually save the current action in
the session, and when the get comes back, pop it out of the session to
place it in the stack. If somebody is interested, I can share that code....
Denis.

RE: Pagination with Struts 2.1.8 ?
Posted by adam pinder <ap...@hotmail.co.uk>.
i prefer pagination to be db based so there is a minimum amount of data retrieved and held in memory. i.e. only retrieve what you will display. don't retrieve 200 records in memory and page through them.

Yes, I'm using it with S2. Include it in JSPs like this
<%@ taglib uri="http://displaytag.sf.net" prefix="display" %>
then, for example for a listing of users:
<display:table pagesize="10" sort="list" defaultsort="1"
uid="user"
name="users"
requestURI="user_list.action">
<display:column sortable="true"
titleKey="label.name" property="name"
href="user_input.action" paramId="id"
paramProperty="userID"/>
<%-- other columns of users --%>
</display:table>
This assumes you have a list of beans called "users" in your action,
with a propertry named "name", with getters/setters.
Of course, if performance is a problem pagination would be best done at
DB level as Adam suggested.

Posted by Zoran Avtarovski <zo...@sparecreative.com>.
We use display tag extensively and it ties into S2 really well.
We¹ve set it up to use DB based pagination so you only load the items you
need and it ties into S2 i18n properties.
We also use jqGrid which is based on jQuery and works really well where you
want ajax based tables.

Pagination with Struts 2.1.8 ?
Posted by Celinio Fernandes <ce...@yahoo.com>.
Hi,
This is a classic requirement.
I have this table, in a JSP, that I have created with the <table> html tag and that i have filled using the <s:iterator>.
This <s:iterator> tag iterates over an ArrayList defined in my action.
There are too many lines and I need to add some pagination functionality to it.
What solutions are out there and which one do you recommend ?
Thanks for your feedback.

Posted by Alex Rodriguez Lopez <al...@flordeutopia.pt>.
Thanks Zoran for sharing your approach, greatly appreciated, I'm
thinking about implementing a similar interceptor, and maybe replace the
i18n one so work is done implicitly with only a change in struts.xml and
the new interceptor.

Re: [Struts 2.1.8.1] Internationalization: how to remain in the
current page ?
Posted by Zoran Avtarovski <zo...@sparecreative.com>.
Hi Guys,
We simplified it for struts to use a simple interceptor. Can¹t show the
exact code due to legal crap, but here¹s the overview.
In our base action we have a String called requestString, with appropriate
getters and setters. We also have a Map<String, String> of unsafe URL¹s and
their safe counterparts. For example if the unsafe url was
deleteObject.action it¹s safe option would be listObject.action
The interceptor uses the following code:
if(unsafeUrls.get(request.getRequestURI()) != null)
responseUrl = unsafeUrls.get(request.getRequestURI());
else
responseUrl = request.getRequestURI();
StringBuffer rStr = new StringBuffer(responseUrl);
rStr.append(³?²);
for (Iterator iter = request.getParameterMap().keySet().iterator();
iter.hasNext();) {
> String key = (String) iter.next();
> if (!"request_locale".equalsIgnoreCase(key)) {
> if (request.getParameter(key) != null) { // you can also include
> your own parameter specific exceptions. With the tag we used to have a comma
> delimited list of excluded parameters.
> rStr.append(key);
> rStr.append("=");
> rStr.append((String) request.getParameter(key));
> rStr.append("&");
> }
}
}
action.setRequestString(sStr.toString());
And then on the page we have:
<div class=²localeFlag²><a
href="${requestString}&request_locale=${localeOpt.lang}" ><img
src="${pageContext.request.contextPath}/image/icons/${localeOpt.lang}_flag.g
if" alt="<s:text name="%{³select.²+ attr.localeOpt.lang}" />"
title="<s:text name="%{³select.²+ attr.localeOpt.lang}" />"
/></a></div>
I had to modify the code to satisfy our people but let me know if you have
any questions. We use a complex parameter filtering process to unsure that
security isn¹t compromised.
We¹ve had to do quite a bit of i18n which has involved implementing DB based
properties and tighter integration with S2 and spring.

[Struts 2.1.8.1] Internationalization: how to remain in the current page ?
Posted by Celinio Fernandes <ce...@yahoo.com>.
hi,
I have a quick and basic question.
Regarding internationalization, whenever a user clicks on a link with a flag, i want to change the locale (language)
of the web application.
That works well with the i18n interceptor.
However i always redirect the user to the home page (home.jsp) when i do that because that is how i have setup the input result :
<action name="changeLanguage" class="ServicesAction"
method="changeLocale">
<result name="input">/home/home.jsp</result>
</action>
My JSP looks like this :
<s:url id="url" action="changeLanguage.action">
<s:param name="request_locale">fr</s:param>
</s:url>
<s:a href="%{url}" theme="xhtml"><img src="<%=request.getContextPath()%>/images/flag_fr.png" /></s:a>
So my question is :
how do you specify the current page in the input result name ?
so that the user stays on the current page when he changes languages.
Thanks for helping.
