I am having a active page with its url like http://localhost:8085/projectName/namespace1/namespace2/namespace3/sell.action?id=22
Now i want get the action name(4th name after the sign /) i.e setuppageforwared.
How to achieve this ? Please help me to know because i read many books of struts2 i could not find anything which solve this problem.
Before i was using PHP framework codeigniter which easily solve this type of problem using uri segment features(click here) . I am aspecting the same here in Struts2.
Given Url String: http://localhost:8085/projectName/namespace1/namespace2/namespace3/sell.action?id=22
Expected Output: sell
Did you look for ActionContext#getName() ?
Edit :
Since you were not clear about it, I suppose you want to get the name of the action being executed from inside the action. So, in your action execute method, you'll have something like this :
String actionName = ActionContext.getContext().getName();

There are different ways through which I know the current route in angular.
I would like to know the previous route. Say for example im in a tab http://localhost:4200/test/testNav/ABC
Now, i click another tab that takes me to
http://localhost:4200/test/SampleNav/XYZ
In the ngOnInit() method of this html "http://localhost:4200/test/SampleNav/XYZ" i want to get the previous url which is /ABC.
this.router.url, this.activatedRoute.snapshot all gives me the currenturl. Is there a way to get the previous url from the available angular components.
Basically when I come to XYZ page from ABC i should do something and when I come to XYZ from CBA i should do something else. Any inputs highly appreciated.
Here comes getCurrentNavigation() used with optional chaining (question mark) because it can be null. There you can take previousNavigation and finalUrl will return you an UrlTree. Next just execute navigation on finalUrl if it is not null.
const urlTree = this.router.getCurrentNavigation()?.previousNavigation?.finalUrl;
if (urlTree) {
this.router.navigateByUrl(urlTree);
}
I have my webpage opened using RFT. In that page, I have a link I want to click.
For that I am using
objMap.ClickTabLink(objMap.document_eBenefitsHome(), "Upload Documentation", "Upload Documentation");
The current page link name is "Upload Documentation"
I know that objMap.document_eBenefitsHome() takes it back to the initial page, what can I use in that place which uses the "current page opened" ?
Many thanks in advance.
There are some alternatives that could solve your problem:
Open the Test Object Map; select from the map the object that represents the document document_eBenefitsHome; modify the .url property using regular expression, so that the URLs of the two pages you cited in your question match the regex.
Find dinamically the document object using the find method. Once the page containing the link you want to click was fully loaded, try to use this code to find the document: find(atDescendant(".class", "Html.HtmlDocument"), false). The false boolean value allow the find method to search also among object that are not previously recorded.
I have an URL which shows me a coupon form based on id:
GET /coupon/:couponId
All the coupon forms are different and submit different POST params to:
POST /saveCoupon/:id
I want to have a convenient way of debugging my coupons and be able to have a way of viewing actual POST params submitted.
I've made a controller on URL POST /outputPOST/saveCoupon/:id which saves nothing, but prints to browser POST params received.
Now I want to have an URL like GET /changeActionUrl/coupon/:couponId which calls GET /coupon/:couponId and then substitutes form's action URL POST /saveCoupon/:id with POST /outputPOST/saveCoupon/:id .
In other words I want to do something like:
Result.getHtml().replace("/saveCoupon/","/outputPOST/saveCoupon/");
With this I can easily debug my coupons just by adding "/outputPOST" in the browser.
You could just use a bookmarklet and javascript to replace all of the forms' action attributes. That way your developer can do it with one click instead of changing urls.
Something like this will prefix all form actions on the page with "/outputPOST".
javascript:(function(){var forms=document.getElementsByTagName('FORM');for(i=0;i<forms.length;++i){forms[i].setAttribute('action','/outputPOST'+forms[i].getAttribute('action'));}})();
I don't understand, at least not everything ;)
In general you can debug every piece of Play app using debugger (check for your favorite IDE tips how to do that) - this will be always better, faster, etc etc, than modifying code only for checking incoming values.
I.e. Idea 13+ with Play support allows for debbuging like a dream!
I have a simple MVC-based JSP application. Something like:
*.jsp -> ControllerServlet -> *Command.java -> *Service.java -> *DAO.java -> Oracle db
A typical link in the application looks like this:
myapp/controller?cmd=ShowEditUser&userid=55
Which causes ShowEditUserCommand.java execute() method to run and will forward to editUser.jsp
In editUser.jsp, they fill in the fields, then click Save which posts to myapp/controller?cmd=ModifyUser which runs ModifyUserCommand.java execute() method which modifies the user data and forwards to viewUser.jsp.
Everything works fine.
The problem is, in ModifyUserCommand.execute() I'm checking to see if the username is unique. If they try to enter a username that already exists, I set an error value to true and errorMessage value to Already in use.
Then because of the error I forward to the original editUser.jsp (not viewUser.jsp) and the error is displayed above the form.
MY PROBLEM IS (finally! ;) -- when the user is returned to editUser.jsp with the error message displayed, the data they entered in the fields is all blanked out. How can I set it so whatever they entered in the fields is still in place?
Any suggestions or advice are greatly appreciated!
Rob
Simplest way would be to pass the form fields back to your editUser.jsp in your forward action in ModifyUserCommand.execute(). You can do that with individual parameters i.e.
editUser.jsp?field1=1&field2=2
Alternatively, you could pass data with other methods - i.e. encoded JSON.
You can then process your fields in your editUser.jsp via the page's request object and set your form field values accordingly.
There may be other ways to do this depending on what underlying framework (if any) you are using. But this is a basic way of approaching it.
I developed a shopsystem. there is a product page, which lists the available items filtered by some select menus. there is also one item detail page to view some content about each product. the content of that page will be loaded out of an xml property file. if one would click the link in the listview of an item, to view some details, an item specific GET parameter is set. with the parameters value, i can dynamically load the content for that specific item from my properties, by altering the loaded keys name.
so far so good, but not really good. so much to the backgroud. lets get to some details.
most of all, this is some SEO motivated stuff. so far there is also a problem with the pageinstance Id in the url for statefull pages, not only because of the nonstable url, also because wicket is doing 302 redirects to manipulate the url. maybe I will remove the statefull components of the item detailpage to solve that problem.
so now there are some QR-code on the products being sold, that contain a link to my detail page. these links are not designed by myself and as you can imagine, they look a whole lot of different like the actual url. lets say the QR-code url path would be "/shop/item1" where item1 would be the product name. my page class would be ItemDetailPage .
I wrote an IRequestMapper that I am mounting in my WebApplication#init() that is resolving the incoming requests URL and checks wether it needs to be resolved by this IRequestMapper. If so, I build my page with PageProvider and return a requesthandler for it.
public IRequestHandler mapRequest(Request request) {
if(compatibilityScore>0) {
PageProvider provider = new PageProvider(ItemDetailPage.class, new ItemIDUrlParam(request.getUrl().getPath().split("/")[1]));
provider.setPageSource(Application.get().getMapperContext());
return new RenderPageRequestHandler(provider);
}
return null;
}
So as you can see, I build up a parameter that my detailpage can handle. But the resulting URL is not very nice. I'd like to keep the original url by mapping the bookmarkable content to it, without any redirect.
My first thought was to implement an URLCodingStrategy to rebuild the URL with its parameters in the form of a path. I think the HybridUrlCodingStrategy is doing something like that.
After resolving the URL path "/shop/item1/" with the IRequestMapper it would look like "/shop/item?1?id=item1" where the first parameter off course is the wicket pageinstance Id, which will most likely be removed as I will rebuild the detail page to be stateless :(
after applying an HybridURLCodingStrategy it might look like "/shop/item/1/id/item1" or "/shop/item/id/item1" without pageinstance Id. another Idea would be to remove the second path part and the parameter name and only use the parameters value so the url would look like "/shop/item1" which is then the same url as it was in the request.
Do you guys have any experience with that or any smart ideas?
The rewuirements are
Having one fix URL for each product the SE bot can index
no parameters
stateless and bookmarkable
no 302 redirects in any way.
the identity of the requested item must be available for the detailpage

As Bert stated, your use case should be covered with normal page mounting, see also the MountedMapper wiki page, for your case a concrete example:
mountPage("/shop/${id}", ShopDetailPage.class);
Given that "item1" is the ID of the item (which is not very clear to me), you can retrieve it now as the named page parameter id in Wicket. Another example often seen in SEO links, containing both the unique ID and the (non-unique, changing) title:
mountPage("/shop/${id}/${title}", ShopDetailPage.class);
Regarding the page instance ID, there are some ways to get rid of it, perhaps the best way is to make the page stateless as you said, another easy way is to configure IRequestCycleSettings.RenderStrategy.ONE_PASS_RENDER as the render strategy (see API doc for consequences).
