Security :: Running A Java Applet In Authenticated Folder
Jul 1, 2010
In one website I am working on we're using a java applet in 2 places: the 1st one in a public area where it works just fine and one in a protected folder where it just doesn't work. The protection is performed with forms authentication. The error is shown below. Any clue ?

I am trying to write an asp.net webpage which contains an applet. Everything works fine when I run this in a development folder, but when I move it to the IIS web server public folder it doesn't work anymore. I don't get any error message. The browser doesn't repaint the applet area Here is the source code:
//web page
<script src="http://www.java.com/js/deployJava.js"></script>
<script>
var attributes = { code:'ImageApplet.class', archive:'ImageApplet.jar', width:864, height:1000} ;
var parameters = {jnlp_href: 'image-applet.jnlp'} ;
deployJava.runApplet(attributes, parameters, '1.4');
</script>
//applet
public void init() {
buildUI();
}
public void buildUI() {
JButton jumbleButton = new JButton("Jumble");
jumbleButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
};
});
add("South", jumbleButton); }

I have a need to integrate a third-party Java applet into a custom web part I wrote for SharePoint 2007. The web part simply loads a user control I created that contains the bulk of the functionality, and that's where the applet will go. I added it to my user control project and it works fine outside of my SharePoint environment.
I installed the updated web part onto my MOSS 2007 development site and the part's page loads fine. The applet is triggered by clicking a link button on the page, which runs some client-side JavaScript to start it. The problem is nothing seems to happen when I click the link. No error messages appear, and the stuff the applet is supposed to do never occurs (it's for doing file transfers via FTP). I have the .jar file as an embedded resource in my user control DLL, which is deployed to the bin folder, and SharePoint fully trusts this DLL.
I used Firebug to step through the initialization code and I saw an HTTP GET that failed with a message about not being authorized, but it didn't give any details and I'm not positive it was related to the applet. Is there anything special I need to do to make the applet work? Or am I going about this the wrong way?
EDIT: The problem turned out to be the .jar file for the applet couldn't be found. SharePoint is clearly doing something different here, and I need to find out what. Can Java applets be used within a SharePoint site? This question suggests they can, but in that case a Page Viewer web part was used, which isn't going to really work for me.

I had came acroos an open source a java applet. I wanted to know is there somehow I could create a script that could be distributed and the applet could be embedded in any website? I have been able to inject jquery and JS scripts into websites by placing a tag pointing to a Javascript file and placing it in the header of the page but I don't know how a java applet can be injected?

I have created a Java Applet that will be used in IE to print images from a remote server. I load the applet in a new popup window from my main web page and it prints fine, but it locks up the new popup browser window while it is printing. When the print job is complete the popup window becomes responsive again. The main browser window remains functional during the printing. Is there something I can do during the printing process to cause it to yield so the popup does not lock up?

I have an aspx page with a java applet. At the end of the execution, the applet navigates to another aspx page, in which there is a button that gives the possibility to execute the applet again. I would like this second page to reload every time the applet calls it, but unfortunatelly this doesn't happen. If I start from the applet's page, all works fine; but if I call the applet's page from the other one, when the applet redirects to this second page the load event does not fire. Probably the code could be clearer, so this is it:
Dummy.aspx
[Code]....
Dummy.aspx.vb

I am using the membership provider and am reasonably comfortable that all of my web pages are safe.Some of the pages contain hyperlinks to documents (pdf, xls, etc.) stored in a folder under the root of the web site. I have disabled the ability of users to anonymously list folder contents, but I don't see a way to keep anonymous users from accessing the documents if they know the specific URL for that document. Example; if the document contains a spreadsheet of current sales, I don't want an ex-employee (who captured the URL while working here) to be able to bring up the current document.asswording the documents isn't a good choice because there are hundreds and we'd like to avoid changing them all every time someone leaves, or weekly, or whenever...Is there a way to restrict access to all contents of a web folder to people who have been authenticated?

I've a default.aspx page in my application's root folder. I added a a page in the root of inetpub that redirects requests to the default page. The idea is that the user need only enter the server name to get to the default page. How can I set things up so that all users have access to the default.aspx and that they only have access to the other pages once they've been authenticated?
I am using Windows Integrated Security and the users are being challenged and authenticated properly. I want them to be able to access Default.aspx without any challenges.
(On a side note which may answer this question, when using WIS does the user *allows* have to be challenged? Isn't it possible to pass through their Windows User and ID without the prompt?)

edirect.aspx (set as default document in IIS and simple executes Response.redirect("sites/mercury/default.aspx")

I have a very simple and stupid problem but I'm unable to find a solution. I'm trying to create folders and files locally through my code, however I get a permission exception when I try to write in a folder in my application. Normally I'd run this on a remote server, and ask the system administrator for writing permission on this specific folder, but I need to run this locally for the moment.
If I navigate to the file in windows explorer, and right click the folder and click on Properties, I can see that it's set as Read Only. However when I try to disable this tickbox and click on Accept, nothing happens. It ignores me, and next time I open the Properties of this same folder, it's still marked as Read Only.
I've googled this and found a solution which implies using MS-DOS and a command named "attrib". This is not working for me either. I also read about adding an ASP.NET account on my PC and granting the right permissions to this, but I'm not sure how to do is.

I have a login page. Once a user is authenticated they are redirected to another page, (called pg2). I don't want just anyone typing in the url and getting to pg2. If they are not authenticated I want them to redirect to login.aspx. To achieve this, I'm using this code below. But it's not working. I am using a nested master page and I don't know if this is causing the problem.

I'm setting up a new web forms app and want to use ASP.NET membership. All my users must be authenticated. What is the best way to implement this?I'd love to deny all unauthenticated users in the root folder of the app by setting this in web.config but then where would I put the login folder? I'd like the login folder to be a subfolder of my root folder so that the URL can be www.myapp.com/login/Another idea is not to put the restriction in the web.config but put the logic in Session_Start in global.asax but I really like the idea of controlling who can see what using web.config files.

I got only one ideas to control with the session. When user log into the master page, I insert the current login user and session ID and active status to the SQL table. if user logout manually or close the browser or session expired, I want to change the inactive status. So I can check how many active user are there and the system can prompt the required info to the user. But now, I can't find the soultion to change the inactive
status in above condition.
That doesn't seem right to me. I m sure I 'm making incorrect assumption about this matter.

we want to have a fronend to a custom databasince, since I do have experiance with HTML/CSS and have used VB.NET before, I'm the one that gets to make it.
problem is, the one thing I have not used before is the autentication system in ASP.NET, I want to use single-signon for the system.
and I do have this right now, the only problem I have is how do I check if a user is logged in, and change the page content for autenticated users.
the template does have this:
[Code]....
which does indeed change the login view, problem is, how do I change this to change the pages and menu.this:
[Code]....
has to be a longer menu that also gives options to insert data into the database and/or remove/update the data.

Show Authenticated user on Intranet:
Response.Write("UserName is: " + User.Identity.Name);
In Web.config:
<authentication
mode="Windows"/>
<authorization>
<allow
users="?"/>
</authorization>
This works fine on local server. But not on Intranet.
On Intranet, it was working fine on IIS 6.0.
But on IIS 7.5, the user doesn't get authenticated.

Ok so I've created a login page that accesses my Active Directory and challenges against it. What I would like, is if a user is logged onto the computer within the intranet with Active Directory Credentials for them to bypass the login to the web page.
However if they are outside of the building on a random computer, they should be presented with a login box just like they are now.
