FTP Adapter to read multiple files from a directory. Not through polling.

Dear Friends,
I would like to know is it possible to configure the FTP adapter in Oracle BPEL 10.1.3.4 to read multiple files (different names, same structure) from a given directory. I do not want the BPEL to do a polling. Instead when I submit the BPEL process it should read all files from the directory.
I was looking at the option of Synchronous read but I am not able to specify wild card in the file name field. I do not know the file names at the time of reading.
Thanks for your help!

Hi,
While you read the file, you can configure an adapter property in 'Receive'. This will store the filename, this filename can be used for sync read as the input parameter.
1. Create a message type variable called 'fileheader'. This should be of type Inboundheader_msg (whatever relevant Receive activity).
2. This variable will contain three parts - filename, FTPhost, FTPPort
3. Copy this fileheader to 'Syncheader'.
4. syncheader can be passed as an adapter proerty during sync read of the file.
During Receive and Invoke, you need to navigate to 'Adapter' tab to choose the created message type variable.
Let me know if you have further questions.
regards,
Rev

Reading a file in the same directory as the JSP files

Hi,
Okay so I have my JSP files in the directory $Catalina/webapps/webservices, I also have a text fire in the same directory called users.txt
All I want to do is open the users.txt from the JSP program and read from it. But JSP can't seem to find the users.txt.
Code I have tried include,
File users = new File("users.txt");
File users = new File("http://localhost:8080/webservcies/users.txt"); Also File users = new File(new URI ("http://localhost:8080/webservcies/users.txt"));
File users = new File("webservices/users.txt");
I guess part of the problem is that I don't know what the JSP working directory is. I assumed it was $Cataline/work/standalone/localhost/webservices
but even if I use,
File users = new File("../../../../webapps/webservices/users.txt");
It doesn't work. Does anyone know how I can read the file? Any help in this matter would be appreciated.

From within a JSP you have a reference to a PageContext called pageContext. This has a method getServletContext(). From the ServletContext you can find the real path the servlet lives in. So...
File basePath = new File(pageContext.getServletContext().getRealPath("/"));Now basePath contains your path $Catalina/webapps/webservices. Then it's just a matter of working relative to that, e.g.:
File usersFile = new File(basePath, "users.txt");

How to open and read many files from a directory and store contents in 2D array?

I want to make a VI that opens and reads the data from various files contained in a directory (200 files each with 2 columns) and store these in a single 2D array. For file number 1 I want to store the data from both columns in the 2D array, but for files 2 to 200 I only want to store the second column of each file. Can someone please help?

Hi Nadav,
Thanks for your help. I have followed your instructions but i cannot get it to work. I used the LIST DIRECTORY to list the files in the directory - that works. However, how do I read each of the 200 files using READ FROM SPREADSHEET FILE without me having to manually select each of the 200 files? So, if I use LIST DIRECTORY to list all 200 files in an array, how do I get each of these to open and store the data in a 2D array? Here is what I have done (File called read_files.VI) Could you please help me? Thank you very much in advance.

I have read 118 files (from a directory) each with 2088 data and put them into a 2 D array with 2cols and 246384row, I want to have aeach file on a separate columns with 2088 rows

I have read 118 files from a directory using the list.vi. Each file has 2 cols with 2088rows. Now I have the data in a 2 D array with 2cols and 246384rows (118files * 2088rows). However I want to put each file in the same array but each file in separate columns. then I would have 236 columns (2cols for each of the 118 files) by 2088 rows. thank you very much in advance.

Hiya,
here's a couple of .vi's that might help out. I've taken a minimum manipulation approach by using replace array subset, and I'm not bothering to strip out the 1D array before inserting it. Instead I flip the array of filenames, and from this fill in the end 2-D array from the right, overwriting the column that will eventually become the "X" data values (same for each file) and appear on the right.
The second .vi is a sub.vi I posted elsewhere on the discussion group to get the number of lines in a file. If you're sure that you know the number of data points is always going to be 2088, then replace this sub vi with a constant to speed up the program. (by about 2 seconds!)
I've also updated the .vi to work as a sub.vi if you wa
nt it to, complete with error handling.
Hope this helps.

Read all files in a directory

I need to compare the date of creation of multiple files that are being created throughout the execution of the application, so that if the date and time of the file is equal to the current date and time, a led will light up, and if not, the file will be deleted.
I've made a VI, but I'm getting an error and I don't know how to fix it.
What I need is for the vi to read all the files in the directory and continue reading all the files as they are created in the directory. The weird thing about this error is that it only shows up when I run it without highlight execution.
Attachments:
Date & Time comparison.vi ‏10 KB

Several things come to mind.
0. What error do you get? The error code or description can be very useful in identifying a problem.
1. When a VI runs OK with execution highlighting and fails without, that usually indicates a timing problem.
2. The inner loop runs as fast as possible because there is nothing in there to slow it down. Put a Wait (ms) in there to slow things down a bit.
3. The loops will never stop. Do not create infinite loops by wiring False constants to the Stop if True terminal. The inner loop should probably be a for loop which will automatically stop after checking all files. The outer loop should have something to stop it - a front panel button, error, something.
4. The timestamp has approximately 19 digits of precision in the fraction of a second portion. The resolution is limited by the clock in the computer. The implication is that you will almost never get exact equality. You need to define "how close" is close enough. Perhaps within 1 second? Then modify the comparison function to determine whether the timestamps are within that limit.

How to read resource file under the WEB-INF through ClassPathResource

I have an xml file under the directory WEB-INF but WEB-INF/classes, I want to read it through ClassPathResource class from Spring, and where I read this xml file is not in a Servlet class, how can I do? Thank you.

Webmethods should be able to handle it. if not you should convert the tline content into one xstring and pass it to webmethods.
othe option
if you are on WAS6.20 and above you can use BSP to achieve what you are looking for.

I can't read a file with the ext PDF the sender informed me that the file was reset to PDF.

I can't read a file with the .ext PDF the sender informed me that the file was reset to PDF. But when I tried to open it the caption box informed me"the file is not in PDF format. I suspect the sender simply changed the file .ext which is why I can't open it! What can I do about it! I am working on an iPad.
Thanks
Mr Jim Lapthorn

If the document is not, in fact, a PDF, then you will need to get your sender to provide a PDF.
Can you open this document in any other application?

I removed chrome 10 and newly installed FF4 final, and I can't read PDF files within the browser. There was no problem in Chrome. I can't even see the acrobat reader plugin in the plugins page. Acrobat 10 is already installed in my PC. Every time I try to read a PDF file on the web, FF tries to download it instead.

As recommended above by Bernd Alheit, I posted this on the Adobe Reader forum. There, I received the advice to repair the installation under the help menu, which I did and it fixed the problem.
Similar to your solution but found it's a fix found under "HELP" menu and not Add/Remove.

How to read, write file inside the JAR file?

Hi all,
I want to read the file inside the jar file, use following method:
File file = new File("filename");
It works if not in JAR file, but it doesn't work if it's in a JAR file.
I found someone had the same problem, but no reply.

Can you help me ? I have tried this for all night !
Thanks in advance
Leo

If you want to read a file from the JAR file that the
application is packaged in (rather than a separate
external JAR file) you do it like this ...
InputStream is =
ClassLoader.getSystemResourceAsStream("filename");Better to use
this.getClass().getClassLoader().getResourceAsStream();
From a class near to where the data is. This deals with multiple classloaders properly.
