How to read OLE objects from Access ??

Hi,
I have an field of type OLE in my Access Database table. This field has some files stored in it in the form of attachment. The file types of the OLE objects can be different (xls,txt,doc). Now, I want to query the database and find the extension of the files and save it occordingly using java.
I'm using the following now.
JdbcOdbcInputStream jois = (JdbcOdbcInputStream) rs .getBinaryStream("SupportingData");
byte[] supportingData = jois.readData();
String data = new String(supportingData);
I'm getting data in binary format and when I try to look into it, all I can see is the header info of the file.
Is there anyother way to read the OLE object easily ?
Please suggest.
Thanks,
Mary

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 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");

Help! Print OLE object from report builder.

Dear OTN Members,
I would like to know how to print out a OLE object from
report builder, because currently I face problem to print out
the whole contain of the winword document file, because when I
display the OLE on the form it will only display according the
size I declare for it, it seems that it will not automatic
extend the size itself. i.e. if I drag the size to one page in
fact the maximum is one page, then when it display, it will only
display maximum one page eventhough the document file maybe
contain 10 page inside it. So when I print out the report it
will only show me one page, so if you have any solution, pls
share with me, thank you.

As far as I know you have to use OLE Item to work with the information. Unfortunately there is not any standart way to extract a source document from OLE. Some applications such as Word, Excel support OLE Automation, so you could use OLE2 package to save the document as a file, that is the easest way. But others don't, so you may have to use an undocumented way to extract a document.
Take a look at the following thread:
Subj: 6i to 9i Ole to LOB translations, How do you know the App. server?
Re: 6i to 9i Ole to LOB translations, How do you know the App. server?
P.S. If you can't extract some types of your documents, please let me khow.
P.P.S. To extract a document through OLE2 package you could use something like the following. /I'm not sure the code is correct/:
DECLARE
handle ole2.obj_type;
BEGIN
ACTIVATE_SERVER('OLE1');
handle := forms_ole.get_interface_pointer('OLE1');
BEGIN
-- Save a document to disk
Args :=OLE2.CREATE_ARGLIST;
OLE2.ADD_ARG(Args, 'C:\test.doc'); -- file name
OLE2.INVOKE(handle, 'SaveAs', Args);
OLE2.DESTROY_ARGLIST(Args);
EXCEPTION WHEN OTHERS THEN
Message('Error');
END;
-- OLE2.RELEASE_OBJ(handle);
END;

Doubt , how to display ole objects in report builder

Please tell me, how to display ole objects in report builder.
I mean i wanted to print ole object in report, so how to do that.

Just to clarify Lixia's response.
In Reports 9i we have deprecated our OLE functionality. Reports created in prior versions that contain OLE objects should still run, but you will not be able to create new reports containing OLE objects.

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.

How to move database objects from one user to another user

Could someone help how to move database objects from one user to another user
Thanks in advance

Thanks a lot for the reply.
Actually I wanted to know whether there is any command to change the owner ship of the table.
For ex table1 belongs to user1. can the owner of table1 to be changed to owner2.
directly using an oracle command. I knew that it can be done using import and export, since the table was 200 million thought the rename command would be faster instead of import and export.
Thanks Billy for letting me know that it is not possible using oracle query.

How to pass an object from jsp to other jsp using SendRedirect

How to pass an object from one jsp to the other jsp using ssendRedirect with out using the session
I am having 2 jsps
x.jsp and y.jsp
From x.jsp using sendRedirect iam going to y.jsp
From x.jsp i have pass an object to the y.jsp
Is it possible without putting the object in session
Is it possible using EncodeUrl
Please help me Its Urgent

Is it possible without putting the object in sessionAnything is possible. Would you accept that it is very difficult?
When you send a redirect, it tells the browser to send a new request for the target page. That means any request parameters/attributes are lost.
Is it possible using EncodeUrl response.encodeURL() puts the session id into a url if the browser does not support cookies. It is purely for retaining the session.
There are two ways that you can communicate across a sendRedirect.
1 - use the session
2 - pass a parameter in the url.
parameters are string based, so passing objects is almost out of the question.
Potentially you could serialize your object, encode it in base64 (so it is composed completely as characters) and pass it as a parameter to the other page, where you retrieve it, unencode it, and then load the serialized object.
Or you can just use the session.

Reading an object from a binary file

i am writing objects into my binary file using printwriter class. i am able to write objects into the file but i am having problems reading the object from the file. is there any other way of going about it. i tried using the objectoutputstream and object input stream class. but i am getting run time errors coz of something to do with serialization
i am storing records as a object into a binary file so that it is easy to seek my records

Of course you have trouble reading objects after you wrote them with a PrintWriter.
You should rather have fixed the Serialization errors: only objkects that implement Serializable correctly can be serialized.

Hi,how can i transport objects from one server to other like (Dev To Qty)

Hi Sir/madam,
Can u explain how can i transport objects from one server to other like (Development To Quality To Production).
Regards,
Vishali.

Hi Vishali,
Step 1: Collect all Transports(with Packages) in Transports Tab(RSA1)- CTO
Step 2: Release the subrequests first and then the main request by pressing Truck button
Step 3: STMS or Customized transactions
Object Collection In Transports:
The respective Transports should have the following objects:
1. Base Objects -
a. Info Area
b. Info object catalogs
c. Info Objects
2. Info Providers u2013
a. Info Cubes
b. Multi Providers
c. Info Sets
d. Data Store Objects
e. Info Cube Aggregates
3. Transfer Rules u2013
a. Application Components
b. Communication Structure
c. Data Source replica
d. Info Packages
e. Transfer Rules
f. Transformations
g. Info Source Transaction data
h. Transfer Structure
i. Data sources (Active version)
j. Routines & BW Formulas used in the Transfer routines
k. Extract Structures
l. (Note) If the transfer structures and related objects are being transferred without preceding
Base Objects transport (e.g. while fixing an error) it is safer to transport the related Info
Objects as well.
4. Update Rules u2013
a. Update rules
b. Routines and formulas used in Update rules
c. DTPs
5. Process Chains u2013
a. Process Chains
b. Process Chain Starter
c. Process Variants
d. Event u2013 Administration Chains
6. Report Objects u2013
a. Reports
