File Adapter - how to get the file count from a folder

Hi All,
I have a requirement that have to poll a directory when the file count is reached to number N (ex:number of files avilable in folder is 5) otherwise it should wait and not pick any of the files. Is it possible to get the file count from a folder using file adapter ?? otherwise please suggest me an approach to achieve this requirement.
Thanks,
JJ

Hi Sarath,
Thank you for your reply.
Go with the list files operation of file adapter it will gives you the number of files in the specified folder as you given. . - this step is already done.
When the number of files reaches your count startup your webservice that which can polls the files. . . - how can i acheive this?? Have to poll the directory and process the number files - please let me know, what could be added to the webservice which is being invoked after cheking file count from parent process.
The reason for the above question is - we cannot use ReadFile operation in second webservice because it will be automatically triggered when the file is avilable. Also SyncRead operation supports reading one file in b/w bpel process. Kindly explain me the implementation steps.
Thanks,
JJ

File adapter polling and getting the file name 11g Jdeveloper

I am using JDeveloper 11g. My process is something like;
A file adapter reads a XML file
This triggers the BPM process, file content is sent to start activity as message
I have to get the file name that is read by file adapter.
How to do that? Any help is appreciated.
I have seen couple of answers like bellow in forum but did not help me much
This is a very simple task in JDeveloper 11g, file adapters are linked to the receive activity, here there is a tab called Properties which you can use to extract the file name. Please follow the steps below:
1. Create a Simple Type variable of string type, call it fileName_var or any name you wish.
2. Open the Receive activity in your bpel project.
3. Scroll down to jca.file.FileName and double click on the value column, click on the browse button (...), select Variable, then click the search icon
4. Locate your recently created variable
5. Now when your project runs it will assign the file name to this variable, you can use this same approach also to pull the directory, file size, etc.
*************************/

hi,
Like you said.. steps are simple and clearly mentioned in guide.
1. create a variable of type string
2. after configuring the file adapter , go to corresponding receive activity , go to properties tab
3. search for a property with name as jca.file.FileName . This basically keeps track of file name
4. for this property, give the value as name of variable created in step 1 above
5. Use this variable anywhere in assign / transform

File adapter polling and getting the file name

I have a requirement where I have to poll a file and dump the data into the DB. But while polling a file for a particular file name, I also need to get the name of the file to do some operations on the file. The file name should be passed from the adapter in order to do some operations based on the file name. Is it possible to get the file name by any chance?

Hi,
its easy to get the file name..by creating the variable for the fileAdapterInboundHeader.wsdl
just follow the below link.

Get the record count from a query

Hi,
does anyone know how to get the record count from a sql query?
e.g: I've got a ResultSet from the Statement.excuteQuery(), and I want to know how many records this ResultSet contains, how to get this?
I'd read thoughout the documents of Statement and ResultSet, but couldn't find a solution, do I have to use another seperate query such as "select count(*)" to do this?
thanks.
Yang Liu

If you are not using a scrollable result set then the following is the best way to do it.
there are several key words in SQL that can be used, the one you are interested in is count();
so if your query at the moment is
"select col1, col2, col3 from my_table where col2=? and col3=?"you can work out how many rows will be returned by executing this command first
"select count(col1) from my_table where col2=? and col3=?"this will return a result set with one row and one column, you can get the row count as follows:
ResultSet rs = ps.executeQuery();
int rowCount = rs.getInt(1);I hope this helps :)

[CS3][JS] How to get the file type of current document

Hi,
How to get the file type of current opening document (e.g., tif, jpeg, png) using JavaScript with Photoshop CS3.
I am using file object the open the files one by one in the folder (the files sometimes don't have the extensions).
If the current document is in tiff format then I need to convert to 8-bit, if its an Jpg image then needs to ignore the file.
Regards,
Karthik

Do you really need to know the file type? What about just checking the bit depth?
var doc = activeDocument;
if (doc.bitsPerChannel != BitsPerChannelType.EIGHT) {//Not 8 bit
doc.bitsPerChannel = BitsPerChannelType.EIGHT;
//do your save etc
}else{
//Ignore

How to get the file size (in bytes) for all files in a directory?

How to get the file size (in bytes) for all files in a directory?
The following code does not work. isFile() does NOT recognize files as files but only as directories. Why?
Furthermore the size is not retrieved correctly.
How do I have to code it otherwise? Is there a way of not converting f-to-string-to-File again but iterate over all file objects instead?
Thank you
Peter
java.io.File f = new java.io.File("D:/todo/");

Sender file adapter is not polling the file.

Dear all,
Sender file adapter is not polling the file.(But Receiver file adapter is getting the file)

It was worked fine for previous SP14.
I have cheked in Adapter monioring also.
Can you help me out of this problem

Dhanabal

Hi Dhanabal,
Is the XI system running on a unix machine ?
If yes, from the OS level for the folder you are using in the file comm. channel, execute the command
<b>chmod 777 <folder_name></b>
The reason for the file to show up in receiver side and not get deleted might be that the xi user mighht be having only read access to the folder...
Thanks,
Renjith.

Sener file adapter has read/pick the files first in first out method.

HI
In my Interface I am Using Sender as File adapter. As per my requirement Sender file adapter has to read the file from file directory. This directory having 1000u2019s of files with some files are same name (time stamp is different) and some files are different name here file adapter has to pick the file with mentioned name in File sender adapter like ZMPSMSGSTATUSMST-.xml .
But source file name is like <TABLENAME>-<TIME_STAMP>.XML (ZMPSWRKFLOWHIST-20090527-150522-628) in file directory.
The file adapter in XI will poll to this directory and picks the file in first- in first-out by sorting according to timestamp.
To do this configuration what I have to do in sender file adapter please give me your valuable inputs.

How to get the column count at the bottom of the column

Hi Friends,
How to get the column count at the bottom of the column
Thanks
Raj

You mean row count? Add another column, click on the fx button and type RCOUNT(1).
If you want just the total you can make it MAX(RCOUNT(1)), hide this column and then add a Narrative View after your report and enter "Total Number of Records: @n" where "n" represents what order your column is from the left side.

Hi,
Thanks for the suggestion. I've been playing around with some of the classes of the java.net package and java.io
Using the URL class i can get the content of the data from a STATIC page and output that response to file so that is does not display to the client broswer.
But this only works if the URL i give points to a static html page.
So the problem i'm getting is if i'm righting in arguments in the URL, this means that server needs to process the arguments i give and its sends back a dynamic result. Because its dynamic the URL class can not handle this and throws me an exception everytime :(

Hi,
What kind of web page do you have? Do you have possibility to for example make RFCs? Then you could trigger events (with parameters that could "return" the values) and the workflow could react to those events. For example your task can have terminating events.
