Access SSL pages from servlet

Hi,
I request your assistance with the following please:
I have a web application running on tomcat4.1 with mySql, for enrolment.
It consists of pages :
1- Welcome page
2- Personal details part 1
3 - Personal details part 2
4 - Authorize to save to database
Page 1 goes to a servlet that sets beans etc..
I need to then proceed to page 2->3->4 with an SSL protocol. I have purchased a certificate and the hosting company has confirmed that it is installed.
I would welcome some direction on how to modify the code from the following :
theURL="page2.jsp";
RequestDispatcher dispatcher=request.getRequestDispatcher(theURL);
dispatcher.forward(request, response);
to get to page 2 within an SSL layer.
Your advice will be greatly appreciated.
Thank you.

Found the solution.
In the doGet method add:
SessionBean1 sessionBean1 = (SessionBean1) req.getSession().getAttribute("SessionBean1");

Stop user accessing portal pages from book marks(favourites)

Hi,
Scenario... a user can log into portal and set pages as book marks in their browser (favourites), then close the ssession(and browser); then reopen the browser and access the page from the book mark, portal forces the user to log in (which is good) but I don't want them to have access to the page book marked, I want them to be always sent to the main page instead.
Is it possible to stop this happening.
Thanks in anticipation
DG

Hi,
I am afraid this cant be done. The only thing is that the user will be forced to login.
Thanks,

Cannot access APEX pages from other IP in the same network

Hi,
I installed APEX 3.0 on Oracle XE (Windows OS). The PC I installed has a static IP (no DHCP and DHCP servie is stopped).
I started the HTTP server and I am able to access the XE database home page and the APEX developer page and admin page. This PC has a static IP too.
When I tried to access the APEX page from another PC. It is not loading the page.
When tried using Internet Explorer it says "Internet Explorer Cannot display the page"
Please let me know whether I missed any configurations to the access the page from another IP.
Thanks.
Niko

Hi,
Most likly the cause is windows firewall. Try the following:
1 - from Control panel select windows firewall
2 - click on the exception tab
3 - Click Add port
4 - for name enter yhe name you want (APEX)
5 - For port number enter APEX prot number
Hope that will solve your problem

Can display Web pages from servlet but not applet?

I have been able to display real-world Web pages from a simple servlet using JDeveloper 3.0, but can't figure out how to do the same from an applet. Any hints?

My previous post had the detail...Probably a simple question from a relative novice. I'm having a problem just viewing web pages by calling them from a "list" of URLs in an applet. I built an applet with a split pane that has a JTree on one side and an "HTML viewing pane" on the other. I can click JTree nodes to display local html files, but I don't understand how to display web pages from the Internet. Do I need something like HyperlinkListener to make the jump to "hyper-world"???

How to access a page from another website in to the portlet

Hai,
I need this specific requirement. In a portlet that is written in jsp, i need to access another page which is running in another server.I will explain what is my requirement clearly.. In a portlet, i have to acess a page from another site, and i have to pass a parameter directly. If i use URL-Based Portlet with passing parameters, It ask the user to enter the parameter and submit the page.. But what my need is, i have to pass the parameter directly. what i am planning is in a new tab, i will add a portlet, where i need to access the another website page..when the user opens that tab, it directly shows that website..... How do i proceed...
Can anybody help me.. Its URGENT....
If possible send me the code..
my mail id: [email protected]
Thanks in advance
damodar

Damodar,
To include an existing JSP page as a portlet have a look in the PDK section http://portalcenter.oracle.com there is lots useful information. The two things you might find most relevant is a paper on creating java portlets. This paper has a section on turning an existing JSP page into a portlet
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/ARTICLES/HOW.TO.BUILD.A.JAVA.PORTLET.USING.PDK.JAVA.V2.HTML
and to pass parameters and events
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/ARTICLES/OVERVIEW.PARAMETERS.EVENTS.HTML
Hope this helps,

Well, have you tried the obvious to add the following permission to your web server's policy file?
grant "file:<wherever my servlet resides>\myservlet.jar" {
permission java.io.FilePermission "c:\j2sdk1.4.1\jre\lib\javax.comm.properties", "write,delete";

Can't access ssl pages

My friend got a PowerBook G4 from a family member. It runs 10.4.11. First thing off the bat: It wont connect using WPA2-Enterprise. Browsing works, but not for any SSL pages. (Safari and Firefox)
I am told it worked just fine. So I suspect someone deleted vital keychain information prior to giving it to him. Could someone direct me how to recover from this.

Hello,
If it's the original 802.11b Airport card, it's limited to WEP or WPA, no WPA2.
TenFourFox is the most up to date browser for our PPCs, they even have G4 & G5 optimized versions...
http://www.floodgap.com/software/tenfourfox/
SeaMonkey seems pretty fast also, with many options...
http://www.seamonkey-project.org/
http://www.seamonkey-project.org/releases/
Might try reapplying the big 10.4.11 combo update...

i have a jspx and inside it there is dynamic bounded task flow , how can i refresh parent page from this dynamic region.
tnanks

Hello,
The "RefreshCondition" attribute into Property Inspector of af:region, you could set the condition (EL expression) to refresh only
the region (returns true) or the parent page (returns false).

Accessing a page from login page without login

hi gurus,
i have a link on my login page, for example-- about company. if i try to access it, it will always ask for login first and then go to that about company page. can i access this page without logging in?
i saw some solutions like hidden region displayed on same login page, but what if i need to navigate to a different page?
nadeem

Hi Nadeem,
As long as the page has no functionality on it - typical for things like "Terms and Conditions" etc, then you can just make that page public. Edit the page attributes and set Authorization Scheme to "-No Page Authorization Required-" and set Authentication to "Page is Public".
That way, the page can be seen by anyone whether they are logged in or not.

Output byte[] (image) to JSP page from Servlet - not working - why??

I'm testing some new code in my servlet. I'm changing the method I use for pulling an image from the db (which is stored in a Blob column) and then displaying it in a Jsp page via <img src="go.callServlet">
The new way works up until the code that outputs the image (bytes).
Here's a snippet of the code -
               rs = stmt.executeQuery("Select image from images");
               rs.next();
               Blob blobimage = rs.getBlob(1);
               int index = 0;
            in = blobimage.getBinaryStream();
            BufferedImage orig = ImageIO.read(in);
            //resize image
            GraphicsConfiguration gc = getDefaultConfiguration(); //calls method in servlet
             BufferedImage image = toCompatibleImage(orig, gc); //calls method in servlet
             final double SCALE = (double)max_Width_Large/(double)image.getWidth(null);
             int w = (int) (SCALE * image.getWidth(null));
             int h = (int) (SCALE * image.getHeight(null));
             final BufferedImage resize = getScaledInstance(image, w, h, gc);
               //convert bufferedimage to byte array
               ByteArrayOutputStream bytestream = new ByteArrayOutputStream();
              // W R I T E
              ImageIO.write(resize,"jpeg",bytestream);
              byte[] bytearray = bytestream.toByteArray();
              bytestream.flush();
              res.reset();
               res.setContentType("image/jpeg");
             while((index=in.read(bytearray))!= -1 ) {
                       res.getOutputStream().write(bytearray,0,index);
             res.flushBuffer();
             in.close();
             //....               I know for a fact that the process of getting the image as a blob, making a BufferedImage from it, having the BufferedImage resized, and then converted into a byte[] array, works! I tested by putting the result into a db table.
I just don't understand why it is that as soon as it gets to the code where it should output the image, it doesn't work. Its frustrating:(
Here's the code I use regularly to output the image to the jsp, works all the time. The reason I've changed the method, is because I wanted to resize the image before displaying it, and keep it to scale without losing too much quality.
rs = stmt.executeQuery("Select image from testimages");
               rs.next();
               Blob blobimage = rs.getBlob(1);
               int index = 0;
            in = blobimage.getBinaryStream();
              int blob_length = (int)blobimage.length();
              byte[] bytearray = new byte[blob_length];
              res.reset();
              res.setContentType("image/jpeg");
             while((index=in.read(bytearray))!= -1 ) {
                       res.getOutputStream().write(bytearray,0,index);
             res.flushBuffer();
             in.close();
//...Can someone shed some light on this trouble I'm having?
Much appreciated.

I hate to bother you again BalusC, but I have another question, and value your expertise.
With regards to using the BufferedInput and Output Streams - I made the change to my code that is used for uploading an image to the db, and I hope I coded it right.
Can you please take a look at the snippet below and see if I used the BufferedOutputStream efficiently?
The changes I made are where I commented /*Line 55*/ and /*Line 58*/.
Much appreciated.

          // Create a new file upload handler
          ServletFileUpload upload = new ServletFileUpload(factory);
          java.util.List items = upload.parseRequest(req); // Create a list of all uploaded files.
          Iterator it = items.iterator(); // Create an iterator to iterate through the list.
          int image_count = 1;

Error while accessing bean created from servlet

Hi there
I have a jsp page form home.jsp where i am collecting user name and password and then directing to a LoginServlet.Here if the user is validated then i create a accMasterBean and store it in Session object which i create here and then redirect to profile.jsp
In the profile.jsp page i am using bean as follows:--
<jsp:useBean id="accMasterBean" scope="session" class="AccountMaster">
<jsp:setProperty name="accMasterBean" property="*"/>
</jsp:useBean>
i am fetching the properties of this bean in profile.jsp itself and try to display as shown below:---
<%=accMasterBean.getAccountNumber() %>
where accountNumber is a property defined inside AccountMaster class
but it gives an error as follows :---
<input type="text" name="emailAddress" value="Exception generated ---javax.servlet.ServletException: Exception thrown on line '205' from page 'D:\\Program Files\\Allaire\\JRun\\servers\\default\\emtech2\\jsp\\members\\profile.jsp'.
