How to read http header from Forms

Hi,
I have a forms application deployed on 10g AS. We are planning to integrate Oracle Identity management with our forms application. Currently, I access my forms application with an url, say http://hostname/forms/frmservlet?config=test. And, I get a Signon form, where I capture the logon and pwd, and specific to the user credential, I show another form. By integrating my appln with Identity management, I would be protecting my resource in the oracle access system, the WebGate component will do the backend authentication process along with the access server and the directoy service. Upon successful authentication, the DN form the LDAP repository (lets say the userid of my forms application) for the user is returned to the WebGate as http header information/cookie by the Access System. Now without altering the code in frmservlet Servlet, I need to capture the http header info (which contains the userid for the forms application of the user) in my default Signon form. How can I capture this?
Can someone please help
Regards,
Suresh

How to access HTTP Header from within Web service?

Hello,
Is there a way to access HTTP header variables like CONTENT_TYPE, CONTENT_LENGTH from within Web Logic web service.
I was able to get the HTTP header variable from within Apache AXIS services by calling context.getProperty(HTTPConstants.MC_HTTP_SERVLETREQUEST
How can i do this from weblogic web service.
I need this to verify the client SSL_CLIENT_DN
In access I can get the header as follows.
HttpServletRequest req = (HttpServletRequest) context
.getProperty(HTTPConstants.MC_HTTP_SERVLETREQUEST);
clientID = req.getHeader("SSL_CLIENT_S_DN_Email");
Thanks

Help read excel path from forms 4.5

i have trigger on when-button-pressed which opens excel file whit HOST like
host('"C:\Program Files\Microsoft Office\OFFICE11\excel.exe" '||cFileName);
My question is: How to read excel path from forms 4.5 whitout any utility or extra pll, because excel.exe is not always on path C:\Program Files\Microsoft Office\OFFICE11
thanks

Storing the path of excel in some kind of file or db-table is not a good solution, for this may change with any version of excel.
Let the operating system decide on its on, just call
HOST('rundll32.exe url.dll, FileProtocolHandler "' || vcFile || '"');
where vcFile is the file you want to open

How to add HTTP Header Response X-Frame-Options:SAMEORIGIN from OWA published via Forefront TMG 2010 to stop Clickjacking

How to add HTTP Header Response X-Frame-Options:SAMEORIGIN from OWA published via Forefront TMG 2010 to stop Clickjacking. I have put the IIS setting X-Frame-Options:SAMEORIGIN on my Internal CAS Server. However as the OWA page is published through
Forefront TMG 2010, the iFrame tag is not blocked when the page is first opened. Only when you login with your credentials to the OWA page inside the frame and the page reaches IIS on the Internal CAS it gets blocked. I want to block it in the first
instance when it is opened from TMG.

Hi,
Thank you for the post.

How to call Java class from Forms 6i?

Hi friends,
I need to call a Java class from my Forms 6i application.
(It runs under WIndows XP. It's a client/server application and I have only the client and the Form builder installed on my PC)
I don't know almost anything about Java's world so your help would be very useful for me.
Could you tell me exactly what i have to do?
I've read in metalink several Notes, but they supposed that the Java architecture is already installed in the computer.... I only have the default installation of Developer 6i... so I would need to know:
- How to install/configure the neccesary to execute Java classes without problem
- How to invoke the .class from Forms 6i.
Thanks a lot
Jose.

And also this one:
Problem Description
Installed Forms 6i Rel 2 on a MS Windows machine. When trying to Import the Java
Classes getting the errors
PDE-UJI0001 Failed to create the JVM
Solution Description
You need to to install JDK 1.2.2 to run the Java Importer. And set the PATH's
and classpath's correctly.
Explanation
1. Download and install the JDK 1.2.2.
Possibly available at: http://java.sun.com/products/archive/
2. Assuming the JDK 1.2.2 is installed in c:\jdk1.2.2 directory and the JRE in
C:\PROGRA~1\JAVASOFT\JRE\1.2 directory; ORACLE_HOME=C:\Dev6iR2.
Set the PATH to
set PATH=c:\jdk1.2.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin\classic;%PATH%
( If you are using ias9i then the JDK 1.2.2 comes with the ias installtion ,
in this case please set the PATH to
D:\ias9i\Apache\jdk\bin;D:\ias9i\Apache\jdk\jre\bin;D:\ias9i\Apache\jdk\jre\bin\classic;%PATH% )
3. Set the CLASSPATH to set CLASSPATH=%CLASSPATH%;C:\Dev6iR2\TOOLS\COMMON60\JAVA\IMPORTER.JAR;.
(If you do not set the CLASSPATH correctly you will get the error
PDE-UJI002 Unable to find the required java importer classes)
4. Now run the Forms Builder by using the command.
C:\Dev6iR2\bin\ifbld60.exe
Now the Java Importer Should Run fine.

How to read appended objects from file with ObjectInputStream?

Hi to everyone. I'm new to Java so my question may look really stupid to most of you but I couldn't fined a solution by myself... I wanted to make an application, something like address book that is storing information about different people. So I decided to make a class that will hold the information for each person (for example: nickname, name, e-mail, web address and so on), then using the ObjectOutputStream the information will be save to a file. If I want to add a new record for a new person I'll simply append it to the already existing file. So far so good but soon I discovered that I can not read the appended objects using ObjectInputStream.
What I mean is that if I create new file and then in one session save several objects to it using ObjectOutputStream they all will be read with no problem by ObjectInputStream. But after that if in a new session I append new objects they won't be read. The ObjectInputStream will read the objects from the first session after that IOException will be generated and the reading will stop just before the appended objects from the second session.
The following is just a simple test it's not actual code from the program I was talking about. Instead of objects containing different kind of information I'm using only strings here. To use the program use as arguments in the console "w" to create new file followed by the file name and the strings you want save to the file (as objects). Example: "+w TestFile.obj Thats Just A Test+". Then to read it use "r" (for reading), followed by the file name. Example "+r TestFile.obj+". As a result you'll see that all the strings that are saved in the file can be successfully read back. Then do the same: "+w TestFile.obj Thats Second Test+" and then read again "+r TestFile.obj+". What will happen is that the strings only from the first sessions will be read and the ones from the second session will not.
I am sorry for making this that long but I couldn't explain it more simple. If someone can give me a solution I'll be happy to hear it! ^.^ I'll also be glad if someone propose different approach of the problem! Here is the code:
import java.io.*;
class Fio
     public static void main(String[] args)
          try
               if (args[0].equals("w"))
                    FileOutputStream fos = new FileOutputStream(args[1], true);
                    ObjectOutputStream oos = new ObjectOutputStream(fos);
                    for (int i = 2; i < args.length ; i++)
                         oos.writeObject(args);
                    fos.close();
               else if (args[0].equals("r"))
                    FileInputStream fis = new FileInputStream(args[1]);
                    ObjectInputStream ois = new ObjectInputStream(fis);
                    for (int i = 0; i < fis.available(); i++)
                         System.out.println((String)ois.readObject());
                    fis.close();
               else
                    System.out.println("Wrong args!");
          catch (IndexOutOfBoundsException exc)
               System.out.println("You must use \"w\" or \"r\" followed by the file name as args!");
          catch (IOException exc)
               System.out.println("I/O exception appeard!");
          catch (ClassNotFoundException exc)
               System.out.println("Can not find the needed class");

How to read appended objects from file with ObjectInputStream? The short answer is you can't.
The long answer is you can if you put some work into it. The general outline would be to create a file with a format that will allow the storage of multiple streams within it. If you use a RandomAccessFile, you can create a header containing the length. If you use streams, you'll have to use a block protocol. The reason for this is that I don't think ObjectInputStream is guaranteed to read the same number of bytes ObjectOutputStream writes to it (e.g., it could skip ending padding or such).
Next, you'll need to create an object that can return more InputStream objects, one per stream written to the file.
Not trivial, but that's how you'd do it.

How to read some images from file system with webdynpro for abap?

How to read some images from file system with webdynpro for abap?
Thanks a lot!

Hello Tao,
The parameter
icm/HTTP/file_access_<xx>
may help you to access the pictures without any db-access.
The following two links may help you to understand the other possibilities as well.
The threads are covering BSP, but it should be useful for WebDynpro as well.
