I have a servlet that functions as a frontend to a digital object repository. Requests to the servlet are in the form of encoded URLs that pass the necessary repository query arguments as parameters. Once the query has been resolved by the servlet, the URL obtained from the repository is then redirected back to the browser using sendRedirect(). This all works ... |
|
I don't think you are trying to forward - that would imply that the user is leaving your website. What you are actually trying to do is invoke someone else's webapp as a subroutine of your own web logic. As Junilu said, the servlet can use HttpURLConnection for that, just like applets do (except that you don't have the "sandbox" restriction ... |
Hi all. For input/output streams : * on the client-side I have a TunnelLiteClient extending BaseTunnelClient. * on the server-side I have a TunnelLiteServer extending BaseTunnelServlet. Then I created the client proxy to take the place of the object, in this case "Math". The proxy has the following lines of code : public class RemoteMathLiteClent extends TunnelLiteClient implements MathInterface { // ... |

Without some sort of intervention, you will never know when a user clicks a link. In order to track the click throughs, you will have to use JavaScript to send the new location to a servlet on your system, you can count it and then do a redirect to the correct URL. The cool thing to do would be to use ... |

Hi, First, I'm sorry if this question may not be directly related to this forum, any suggestions for more appropriate web sites will be appreciated. Is there a way to have a web application find and open a file on the clients machine? I would like to be able to create a link that will open a file, html or image, ... |
Hi, I have to work on web application where i need for the user to logon with userid and password for some functions. So it will be some thing like the user clicks submit after entering the data on a screen, but then i want to show a page for the user to login, and if the login is successfull then ... |
I suggest using an Entry *Filter* to achieve this since 1. The logging can be directed to wherever you want it to be (file/ db) 2. You can selectively log certain JSPs only 3. You can stop the logging at any time you want it by turning it off in web.xml In you web.xml, define the filter like EntryFilter ... |
Changing the client ID for example. Basic security means that the servlet cannot trust anything being requested from a page. You validate the session id (a filter can check if the user has logged in and is authenticated), but I want to prevent an already authenticated client to see products of another client by changing the URL. Or am I reading ... |

Hi, I have a tree of items in a web page which the user can click on to expand, which when they do, will submit a form and go to the servlet to process the results. It will then populate the expanded branch with the items and show the page again. Now, if the user had to scroll down the page ... |

19. Hide URL coderanch.comWe use Sun One Portal server that allows for single sign-on for the users to multiple applications. In one of the applications, the user will request for an Actuate e.Report after providing input parameters in a JSP page. An URL will be formed with a given input which calls the Actuate report's execute command. The requirement is to hide this URL ... |
Hi there, I have the following configuration: Tomcat, JSTL, Struts. 1. The Tomcat's server.xml contains the following context section: the docBase elements points to the location where previously I have unpacked the application's war file. 2. Used is JSTL's tag to ensure URL encoding (for disabled cookies scenario). ... |
With regards to your question: what are you trying to do? Is it enough that the url in the address bar remains the same, but the actual page address changes but can be discovered by the user? If so you can use frames to hide the inner frame changes. You may want to look at a pattern called the Front Controller, ... |
Hello All, I am working on a java web application and have the need to preserve a URL that throws a 404 error.

Hi I have a requirement where in the URL displayed on the browser address bar should not change whatever link you click from page and however you navigate.

|
As Jeroen said, i dont think this can be done directly. However i think this can be done programmatically... here is how i think i would do it: 1. Let one servlet handle all requests. 2. In the servlet, use HttpServletRequest.getServletPath() to get the name of the servlet actually required. 3. once you get the name os the servlet, get it ... |
I am putting together an application that will be used by different companies. I would like to be able to figure out which company is accessing my application based on url.

Lets review what happens when a servlet gets a request. 1. Before your service method gets called, the servlet container constructs a request object and a response object. The request object is populated with the HTTP headers parsed out of the request. We are talking lots of String operations here, with all header lines parsed and placed in a Map.This is ... |
Hi, I guess you mean that the result should be shown in a new browser (window). In that case it is not controlled by the server but has to be configured in the calling html page. e.g. in case you are submitting a page you can change the target attribute of the form or anachor element. |

You can not use request dispatcher for dispatching requests to outside a container , even you cannot dispatch to some other application in the same container. If you want to use the same request for this and having attributes attached to it , it might be difficult.But in case you do not have any request attribute then you might request the ... |
my issue is not with the post actually the module has already been done and i cannot now go place dopost() method at each and every action class.so i just need one more alternate way such that any user types at the url it must not navigate to the next jsp page . |
Hi there, If you find the hex value of the characters you need to pass in, you can use those. the hexadecimal value for a space is 20, and in a URL you can encode this as %20 the caret is %5E the pound character is %23 I'm sure some good references should come up if you google "url encoding" or ... |
I need to send a url to my servlet to another server that will use the url to place a 'callback' link to my servlet on their page.

I have an applet that does some Java3D stuff. No problems there, but I want that applet to pull files (3D images) over the Internet for use in a CompressedGeometryFile. That class only has the following constructors: CompressedGeometryFile(java.io.RandomAccessFile file) CompressedGeometryFile(java.lang.String file) Unless an applet is signed, you can't do the RandomAccessFile thing across the Internet I believe. If the constructor would ... |
Explicitly get the URLConnection object associated with the URL using getConnection(), get the input stream from that object instead of directly from the URL, and be sure to call close() on the URLConnection itself after the request. It may be counterintuitive, but this is what is necessary to tell Java it's OK to reuse the connection. |

I use URLs for some pretty pedestrian stuff ... downloading files from web servers, checking to see if web servers are running and giving correct results. You could make a servlet read the content off Yahoo and write it out in the middle of your own HTML, but that would be unsanitary and antisocial. I think some portal technologies do that ... |

I think you misunderstood what Joe was saying. The RFC document he pointed you to describes in detail what a valid URL looks like. With that knowledge you can write code (possibly using regular expressions and other string operations) that checks whether a piece of text is (or contains) a valid URL. |
Here is easy solution for mention issue. You can achieve this by submitting request to server using POST type of request. If you are using links (
In general POST type of request wont be displayed in Browser URL (address bar)

Hey, I think there might be a few ways you could get around this, you could use javascript to make an AJAX request to get the data so that the page doesn't change. You could also send a redirect back to the plain url and stored something in the session that the servlet picks up. I wouldn't use either of these ... |

It is possible. You just need to create a front Controller servlet ,redirect every request to your front Controller and you are done. Now the servlet you want to call will be passed as a parameter for any form submitted. Then you can just include that servlet using the include method and you are done. |
