How to convert bytes[] into multipage File object

Hi,
How to convert bytes[] into multipage File object??
I used the java.io.SequenceInputStream to concatenate two input streams (basically .pdf files) into a single input stream. I need to create a single multipage pdf file using this input stream.
Thanks for you help in advance..

Only text format allows you to concatenate two files together to get a longer files.
Most formats have a header and a footer and so you cannot simply add one to the other.
You need to use a PDF API which will allow you to build the new document (if one exists)

I used the java.io.SequenceInputStream to concatenate two input streams (basically .pdf files) into a single input stream. I need to create a single multipage pdf file using this input stream. Then you need a pdf API, like iText or fop. You can't just concatenate pdf files, word docs, excel sheets, etc., like you can text files. Google for java pdf api.

If i write an integer value instead of "count" then Unhandled exception type Unsupported Encoding Exception error is left.This is elementary. You need to go back to [http://java.sun.com/docs/books/tutorial/|http://java.sun.com/docs/books/tutorial/] .

Hi,
How to convert .class into .jar fileFrom a command prompt, cd to the location of your .class file(s).
If you want to create a simple jar, use: jar -cf Whatever.jar Whatever.class
If you want to compile all .class files in a directory into a jar, use *.class instead.
Now, I'm going to assume you want to create an executable jar... here's how to do that:
1) Create a blank text file; for this example, lets call it main.txt.
2) In the first line of main.txt, type: Main-class: Whatever ('Whatever' should be the name of the class in your program where the main() method is located)
3) Press enter to go to the next line (someone please correct me if I'm wrong, but if you don't insert the line break/CR after the Main-class: statement, this will not work... in my experience, this is true)
4) Make sure you save this file in the same directory as your .class file(s).
5) Type: jar -cmf Whatever.jar main.txt Whatever.class
...and that's about it. For more information on the usage of the jar command and to understand the switches (such as -cmf), try jar --help.
Hope that helps.

Converted WSDL into .java-files - and now?

I should implement a client for an existing web service. All I have is a .wsdl-file of the web service to call.
Therefore I used the eclipse's functionality to convert .wsdl into .java files, which generated some files for me, for example:
- interface XXX extending java.rmi.Remote
- interface XXXService extends javax.xml.rpc.Service
- class XXXProxy implements XXX
- class XXXServiceLocator extends org.apache.axis.client.Service
- class XXXSoapBindingStub extends org.apache.axis.client.Stub implements XXX
- class XXXRfcException extends org.apache.axis.AxisFault implements java.io.Serializable
- class XXXRfcExceptions implements java.io.Serializable
My question... what to do now? How can I get the service and call its functionality?
Your help is really, REALLY appreciated...

Hi,
Write client application like below.
public class Client{
public static void main(String [] args) throws Exception {
// Make a service
XXXService service = new XXXServiceLocator();
// Now use the service to get a stub which implements the SDI.
AddressBook port = service.getAddressBook();
// Make the actual call
Address address = new Address(...);
port.addEntry("Russell Butek", address);

Converting pictures into PDF files

How do I convert pictures into PDF files, is this possible?

If you want to use acrobat reader, you have to pay for it.
So, I use other free or cheap apps to do so =>
* powerpdf
* dragonprinter (draakprinter in dutch)
* writepdf
* scanapp (to convert parts of a picture)
I even think that almost every scan-app can convert pictures into pdf's.

What is the efficient way of insert some bytes into a file?

Hello, everyone:
If I want to insert some bytes into a file (for example, insert the bytes before all the original content of the file, or append the bytes to a file), and the size of the original file is very big. I am wondering what is the efficient way? Where can I get some sample codes?
regards,
George

Thanks, DrClap.
I have tried your method and you are correct. I have written a simple program which can be used to insert "Hello World " to the start of a file ("c:\\temp\\input.txt"), and I have verified that it can work. Please help to see whether it is correct and whether it has a more efficient way.
public class TestDriver {
     public static void main(String[] args) {
          byte[] back_buffer = new byte [1024];
          byte[] write_buffer = new byte [1024];
          System.arraycopy("Hello World".getBytes(), 0, write_buffer, 0, "Hello World".getBytes().length);
          int write_buffer_length = "Hello World ".getBytes().length;
          int count = 0;
          FileInputStream fis = null;
          FileOutputStream fos = null;
          try {
               fis = new FileInputStream (new File("c:\\temp\\input.txt"));
               fos = new FileOutputStream (new File("c:\\temp\\output.txt"));
               while ((count = fis.read (back_buffer)) >= 0)
                    fos.write(write_buffer, 0, write_buffer_length);
                    System.arraycopy (back_buffer, 0, write_buffer, 0, count);
                    write_buffer_length = count;
               //write the last block
               fos.write(write_buffer, 0, write_buffer_length);
               fis.close();

There is no automatic way to do this in JDeveloper. I know there are some Oracle Partners offering forms to java conversion, I don't know how much of their tools are automated and done with JDeveloper. With JDeveloper+ADF you basically rewriting the Forms application from scratch (and using ADF is helpful during this process).

How to convert IDOC to flat file in XI

Hello SDNers
I have a scenario IDOC --> XI --> Flat file. My question is how to conver IDOC to flat file. At least there are two ways to do that:
1) Define a flat structure in PI that reflects the IDOC structure, then using content conversion to convert the flat structure to flat file in hte receiver communication channel.
2) There is a [document |https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/46759682-0401-0010-1791-bd1972bc0b8a] talking about using a generic ABAP mapping to map any IDOC to flat file.
For the option 1, I don't want that way, because I would need to define a flat structure in PI for each IDOC which is too much effort. (I would have dozens of IDOC scenarios)
The second one is very attractive. However the document is not complete to follow. Basically it does not explain how the inbound flat structure looks like. I guess the generic ABAP mapping is used to map any IDOC_XML structure to a flat structure, then in the file receiver communication channel to convert the flat structure to flat file format. But the document does not mention how the flat structure looks like. Has somebody tried this scenario? If yes, can you please let me know the steps to do in ESR (IR) and ID? Basically what structure the IDOC_XML should be mapped to using the generic ABAP mapping class?
Or somebody has other ideas on how to convert IDOC to flat file?
Thank you so much
Eric

> 1) You are saying that for Java mapping and abap mapping, the target data type (messag type) is just a dummy one, the real (XML) message the receiver will recieve is the one (stream) produced by the java or abap mapping. Is that correct?
Definitely yes!
>
> 2) For the abap mapping option, I would define a dummy target data type. Do I need to do any content conversion in the receiver adapter (communication channel)?
None wat so ever.The output of your Java Mapping will be the Native Idoc Format.
>
> 3) I tried with a dummy target data type as mentioned in my second post, can you see any clue in the error message what is wrong?
Dats one thing I cant help much. Just make sure that the ABAP report is valid and take the help of a ABAP'er to debug what is going wrong. Not much of a ABAP guy, can read ABAP code, but cant write one myself
Try to test the program standalone to see how it works. Maybe take some Idoc XML file as input and then dump the output to a .txt file and so on.
Regards
Bhavesh
PS : All this is from what I have read of this guide. I have not convert Idoc XML to Native Idoc but have used this guide to convert Native Idoc to Idoc XML .
