Sending PDF as attachment using Business workflow from Java WD

Hi,
It seems it is famous and known may be solved issue. But i am not able to conceptualize the information available. Thats why i am posting this. pls suggest me how to proceed.
My scenario: I have an online intercative form in java webdynpro application where as once user completes data entry on send button click, i am triggereing an workflow of ECC6.0 which sends mail to MS exchange mail ID. Once user gets the form and complete comments section i have another application which allows user to upload the file which is similar to offline case. But when i send the attachment i am getting mail with pdf attachment but when i open PDF i am getting error. And it seems PDF doesn't contain data(as size of pdf is 1 KB). and i tried to use xstring as input type.
Can anyone pls guide me how to proceed.
Regards
Ravindra.

A pdf file is definitely not a text file. Storing it in a Java String is a mistake.
Is the "body" variable in your code a String? How does the data get into
the String?

Want to send PDF as attachement using Java Mail

HI,
I am using Java mail API for sending PDF as attachment. Here is my sample code
messageBodyPart = new MimeBodyPart();
messageBodyPart.setDataHandler(new DataHandler("String data for PDF using iText", "text/plain" ));
I am generating String for PDF file using iTEXT but I am unable to find out mimetype for passing into DataHandler as second paramete.
Any idea?
Thanks
Shailesh

Don't convert the data to String. It isn't text so
you'll damage the binary content by doing that. In
the "demos" directory of your JavaMail download
you'll find a ByteArrayDataSource class you can use
instead of a FileDataSource. Yes, this worked for me. I create the pdf in memory as as StringBuffer and I just changed the code from
messageBodyPart.setDataHandler(new DataHandler(pdf.toString(), "application/pdf"));
to
messageBodyPart.setDataHandler(new DataHandler(new ByteArrayDataSource(pdf.toString(), "application/pdf")));
and it worked.
Thanks a lot for your help,
Dennis

Using word/excel from java (client or weblogic server)

Hi everybody,
i want to use excel / word functionality from java in two different variants:
-> serverside
-> clientside
I tried the weblogic.comc and i got serveral classes but in the remote-package i got only a utitlity-class.
My knowlege about COM is rather bad.
Does anybody did this bevor and
-> can say me, if it is correct, that i only got a utility-class (so how will i use it from the client ?!)
-> has a example for using Excel / Word from Java in bea weblogic
-> has a example for using Excel / Word directly in a client (not via rmi)
Thanks
Ciao

Sven, This is a really bad idea. Why don't you tell me
what your trying to do and I wil surely give you a better alternative

Use a scanner from Java

Hi all!, someone knows about an API that let me use a scanner from Java?
without programing JNI code.
thks in advance!.

The Java Twain package from http://www.gnome.sk does exactly what you need. You do not have to bother about jni, you can get an image from the scanner directly from your java application.

Service command in Preview.app - Send PDF as attachment doesn't work

I have used the following workflow for month on all my three macs.
I open up a PDF file in Preview and select "eMail PDF as attachment" from the Edit menu at the top of the screen. This will attach the current viewed PDF file to a new mail message.
I guess after updating to 10.7.2 somehow it stopped working on MacBook Pro and iMac. My Mac mini is fine.
When I do use this command I get two error messages. Service not available. Can't attach PDF to mail. Import failed. Something like that.
Does anyone know how to fix that? I repaired permissions and did all that kind of stuff.
Thanks in advance!

Would it be possible, please, for someone who has/had this issue to send me the com.apple.ServicesMenu.Services.plist files from ~/Library/Containers/com.apple.Preview/Data/Library/Preferences and from ~/Library/Preferences?
Thank you.

Issue Transporting Business workflow from one System to Another

Hi All,
As there are many limitations in Import/Export of Workflow I'm going for a Transport of Workflow from one sytem to another.
There are some query's reagrding transporting of the Business Workflow through Transport Request.
1)   How can get the Transport Request no. of the Workflow to be transported? (As there are no direct versions displayed from menu).
2)   If there are any dependent objects first how to find the dependent objects lof workflow like if any data element, Domain, Table, Structure (if these objects are used in your WF definition or may be BOR method), Function module, function group BOR, Rule, WF template, task and Task assignment ?
3) How to get Transport Request no. of such dependent objects specifically The Task,Rule , WF template etc.?
4) I have object Type ZBUS2081 related to it how can i get its TR ?
Please describe as I'm new to workflow.
Please identify if there can be some issues after transporting workflow .
Regards,
Ujjwal

Hi Ujjwal,
Please find the below hint's.
1. Regarding the objects included in the Transport request check the Tables - E070*.
2. For dependent objects, you should check the workflow template. You have to check all the Task's and in the task go to
   utilities ---> Object directory entry --> Lock overview . Here you can see the request. It will show you the current request for    the Task.
3. To get the TR for Business object, Go to basic data ---> Transport data --> Here you can see the Request ID for the business object.
Thanks,
Viji.

Sending File as attachment using Mail adapter with naming convention

Dear All,
I am working on a scenario in which my sender file adapter is sending one file named 'ABC.ok' in one of the folders in application server. I have to send the same file with the same name to one of the folders at FTP and also to my customer at his email id.
I have used File Content onversion at the receiver side and has selected adapter specific attributes due to which the required file is getting generated at FTP folder with the same name as that of the source. But how to send the same file using the mail adapter by keeping same name as "ABC.ok". Kindly guide me out in this.
Regards,
NJ

what you need to do:
1) Select ASMA in Sender and receiver File CC...already done
2) Using the Dynamic Config UDF get the sender file name in the field Content-Type...for this you need to have a return statement in your UDF
3) now before pushing this file name to the Content-Type you have to append (concat)the actual type of the file content (xml, txt)
so your entire Content-Type node will have something like text/plain; name="abc.ok"
SAP Note has reference on how to do this:

Q: How can I set the file name of a mail attachment?

Converting Sender File as attachment using PayloadSwapBean module

Hi Expert,
I have a scenario where I have to pick up a file from PI & send it to another PI server as an attachement using XI Adapter.
I went through SDN & found several messages describing configuration for attachement for mail & SOAP adapter.
I attached PayloadSwapBean in my sender File channel & passed keyname as Conent-Disposition & keyValue as attachment however I dont see file being converted as an attachment in SXMB_MONI. It still shows it as main payload.
Please help me on how to convert a sender file payload into attachement. I would like to keep attachment name same as file name. Let me know how we can do that. I also noticed that on receiver XI adapter (which I would be using to send data to next PI system), you can't attach modules. Let me know if there is some other standard way of achieving this requirement.
Thanks
Regards
Sushil

Hi Stefan,
No, I dont see dynamic configuration values in second PI system. I am able to see them in first system.
Hi Amol,
Do you see dynamic configuration in second PI? I am still referring ASMA in second PI system as file parameters? Should it be HTTP header? (How are you referring ASMA in second PI). Below is my code which give me null at run time.
DynamicConfiguration dCon =(DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey dKey = DynamicConfigurationKey.create("http:/"+"/sap.com/xi/XI/System/File","Directory");
String FileDirectory = dCon.get(dKey);
return FileDirectory;

Using Inbound IDOC from Java system creation of Outbound delivery

Dear Experts,
The scenario we are having is really very interesting. Hopefully its a good learning for me and also for others also.
The scenario is,
After sales order creation the details will be sent to one Non SAP system (Java) for performing some tasks related to forwarding agent decision, shipping date and etc. Once the details are finalized in that Java system then, the details needs to be transferred to SAP as "Inbound IDOC" process. For this proposed to use the SAP Jco middle ware.
Once the details transfered from Java system to SAP then, the outbound IDOC needs to get generated automatically. Assuming the stock for that sales order line item is available. Also one more complexity is, our client is using custom transaction (ZVl10C) for delivery creation.
Now Query is,
1. Which IDOC, message type and Functional module needs to be used for creating the delivery automatically..??
2. As per assumption, stock of that sales order line item should be available. Due to some business reason the stock was removed during inbound IDOC transfer then, what will happen to the IDOC..?. How to avoid this situation..??
3. As we told we are re going to use SAP Jco b/w SAP & Java system. In this case, how the data will get transfered from Java system to SAP..?
Thanks in advance for the replies I am going to get

VEL

Use Acrobat Reader from Java

Hi everybody!
Can anyone tell me, how I can call the Acrobat Reader from Java, open a pdf-document and make a snapshot fo the first page?
I have to create an Image file of a page of a pdf-file.
I already tried pdfbox and iText, both do not work.
So using Acrobat seems to be the best solution, from my point of view.
Any suggestions?
Thx in Advance!
Stef

Jeah, I did, but nothing usefull there.
Perhaps it is possible to open a pdf and save a sanpashot of one page as an image using commandline or jscript?
Any hints, ides?

Using ExecutorService class from java.util.concurrent package

Dear java programmers,
I have a question regarding the ExecutorService class from java.util.concurrent package.
I want to parse hundreds of files and for this purpose I'm implementing a thread pool. The way I use the ExecutorService class is summarized below:
ExecutorService executor = Executors.newFixedThreadPool(10);
        for (int i = 0; i < 1000; i++){
            System.out.println("Parsing file No "+i);
            executor.submit(new Dock(i));
        executor.shutdown();
        try {
            executor.awaitTermination(30, TimeUnit.SECONDS);
        } catch (InterruptedException ex) {
            ex.printStackTrace();
        executor.shutdownNow();However, the code snippet above creates all the 1000 threads (Dock objects) at once and loads them to the executor, and thus I'm worrying about memory leak. I haven't tested it on 1000 files yet but just on 50 small ones, and even if the program prints out "Parsing file No "+i 50 times at once, it executes normally the threads in the background.
I guess the write way would be to keep the number of active/idle threads in the executor constant (lets say 20 if the thread pool's size is 10) and submit a new one whenever a thread has been finished or terminated. But for this to happen the program should be notified someway whenever a thread is done. Can anybody help me do that?
thanks in advance,
Tom

Ok I found a feasible solution myself although I'm not sure if this is the optimum.
Here's what I did:
        ExecutorService executor = Executors.newFixedThreadPool(10);
        Future<String> future0, future1, future2, future3, future4, future5, future6, future7, future8, future9;
        Future[] futureArray = {future0 = null, future1 = null, future2 = null, future3 = null, future4 = null, future5 = null,
        future6 = null, future7 = null, future8 = null, future9 = null};
        for (int i = 0; i < 10; i++){
            futureArray[i] = executor.submit(new Dock(i));
        }I created the ExecutorService object which encapsulates the thread pool and then created 10 Future objects (java.util.concurrent.Future) and added them into an Array.
For java.util.concurrent.Future and Callable Interface usage refer to:
[http://www.swingwiki.org/best:use_worker_thread_for_long_operations]
[http://www.particle.kth.se/~lindsey/JavaCourse/Book/Part1/Java/Chapter10/concurrencyTools.html]
I used a Future[] Array to make the code neater. So after that I submitted -and in this way filled up- the first 10 threads to the thread pool.
        int i = 9;
        while (i < 1000){
            for (int j = 0; j < 10; j++){
                if (futureArray[j].isDone() && i < 999){
                    try{
                        i++;
                        futureArray[j] = executor.submit(new Dock(i));
                    } catch (ExecutionException ex) {
                        ex.printStackTrace();
                    } catch (InterruptedException ex) {
                        ex.printStackTrace();
            try {
                Thread.sleep(100); // wait a while
            } catch(InterruptedException iex) { /* ignore */ }
        executor.shutdown();
        try {
            executor.awaitTermination(60, TimeUnit.SECONDS);
        } catch (InterruptedException ex) {
            ex.printStackTrace();
        executor.shutdownNow();
    }Each of the future[0-9] objects represents a thread in the thread pool. So essentially I'm check which of these 10 threads has been finished (using the java.util.concurrent.Future.isDone() method) and if yes I replenish that empty future[0-9] object with a new one.

Call a C++ services using an uuid from java

I need to call a C++ services which is using the UUID for RPC. The interface is having the UUID. The previous client program is also in C++, they have used RpcBindingFromStringBinding(UUID value, .,.,.) to call the interface. Right now I need to call this service from Java using the UUID. Can anyone help me in it.

Passing the UUID should be the easy part, the tricky bit is performing an RPC from Java to C++. How are you doing that? Once you sort that out, passing arguments should be straight forward.
Note: Java's RMI only works between a client server running RMI. To connect to C++ server, you need to use a Java client library which is compatible with your C++ server.
If you still don't know how to perform the RPC call, I suggest you contact the people supporting the C++ program as they should know how RPC calls are made currently. If they don't know, it is highly unlikely we can guess a solution unless you are willing to change the C++ server to use a known RPC mechanism.
