How to read files from cq5..

Hi,
Here i want to get a pdf file from the "/content/myproj-data/docs/demo.pdf" path and then want to convert this into images...(I am using cq5.6.1)
Whenever i started this process using the File I/O stream, i am not able to get the pdf file from the above path .....whenver i took from the static localpath (d://files/demo.pdf) i am able to fulfill my requirement ..
Here whats happening is, when pass /content/myproj-data/docs/demo.pdf to the InputStream , it is changing as "\content\myproj-data\docs\demo.pdf" (Instead of "/" itz taking "\").
Is there a better way to read pdf file from cq5 and convert into image??
Please share!!!
Thanks in advance

what kind is the different machine?
if it is UNIX,you can use following code:
URL url = new URL("ftp",server,port,file);
InputStream reader = url.openStream();
reader.read()
if it is windows,you may be need to install a FTP agent.

[Urgent] How to read files from different directories?

I am new to Java Programming, I would like to know how to read files from directories other than the current one? (example as follows)
ProjectDirectory

What should I write in the MainProgram.java so that I can use the supplementProgram.java from MainProgram and read the Image.gif file from the MainProgram.java?

How to read file from server

Hi,
When i try to read file from server,the following message is displayed .
ORA-29532: Java call terminated by uncaught Java exception: java.security.AccessControlException: the Permission (java.io.FilePermission /tmp read) has not been granted to EWMTRACKTEST. The PL/SQL to grant this is dbms_java.grant_permission( 'EWMTRACKTEST', 'SYS:java.io.FilePermission', ' /tmp', 'read' )
ORA-06512: at "EWMTRACKTEST.GET_DIRLIST_EWM", line 1
ORA-06512: at line 1
thanks and regards
P Prakash

it seems obvious, user EWMTRACKTEST doesn`t have access to directory /tmp and the file under that.
try to give read permission and try again.
you could use command line like 'chmod' to grant permissions.

How to read file from remote machine

Hello,
Hi, i would like to know how to read text file from remote machine using java source code, any code ?
Thanks very much;
Best regards
Kim

On the server, perform the following steps:
Parse the request and determine the file to serve
Open a FileInputStream to the appropriate file
Obtain a reference to the Servlet OutputStream
Pipe the bytes from the file to the output stream
Flush and close the streamYou might want to call HttpServletResponse.setContentType("application/octet") to indicate to the browser that a file download will be occurring. Do so before getting the reference to the Servlet's OutputStream.

How to read file from prsntn server in Inbound idoc FM.

Hi Experts,
I am new to idoc.
I have requirment that i need to read a file from presentation and application server and put in inbound idoc FM.Idoc will be processed in batch.
How can i put selection screen in FM and read the file?or how can i proceed with the solution?
Please help..
Umesh

Hi Umesh,
My understanding on your requirement is to read a file from pres. server and pass the data to an IDoc function module. Am I correct?
If this is the case then you can create a report which picks up the file from pres. server and then read data from the file and pass it to the parameters of the required function module.
Hope this helps.

How to read file from server if I have a logical file path?

Hi guys,
I'm having a pretty "on the run" question,
My program is currently reading a file from server using "open dataset" with file path like this (just example)
/usr/interface/abc/bcd/testfile.dat
Now I got a requirement to make it more consistent to read files, instead of reading that physical file name, I should read the files from a specific folder using logical path.
So I go to T code "FILE" and created a logical path called ZABC_FILE_PATH, unix compatible, with physical path is (for example),
/usr/interface/<sysid>/<client>/<filename>
My question is, can I still use open dataset statement to read this? if yes, how do I do that? If no, there should be alternative way, please let me know what you think. Thanks,

Thanks all, I figured it out.
ONe thing is that typo double quote
The other thing is the importing part, I need the full file path.
CALL FUNCTION 'FILE_GET_NAME_USING_PATH'
EXPORTING
    CLIENT                           = SY-MANDT
    logical_path                     = 'ZABC_MY_LOGICAL_FILE_PATH'
*   OPERATING_SYSTEM                 = SY-OPSYS
*   PARAMETER_1                      = ' '
*   PARAMETER_2                      = ' '
*   PARAMETER_3                      = ' '
*   USE_BUFFER                       = ' '
    file_name                        = v_1
*   USE_PRESENTATION_SERVER          = ' '
*   ELEMINATE_BLANKS                 = 'X'
IMPORTING
    FILE_NAME_WITH_PATH              = v_what_I_need
* EXCEPTIONS
*   PATH_NOT_FOUND                   = 1
*   MISSING_PARAMETER                = 2
*   OPERATING_SYSTEM_NOT_FOUND       = 3
*   FILE_SYSTEM_NOT_FOUND            = 4
*   OTHERS                           = 5
I really appreciate your contributions, thanks again!

Dynamic Routing? how to read files from 2 different directories?

i need to do that..pick files but from 2 different locations..
any simple idea?
yes, the best simple is to have 2 bpels listenening to each directory...
can i create only 1 BPEL?
i heard about Dynamic Routing...too complex?
Thanks!
Pablo.

Hi,
I guess you can try it with Pick as the initial activity( With Create Instance Checked) and you map your two File Adapter to two On Message branches..
I guess this should work but i am not sure how far this is reliable.. with Pick..
Worth giving a try..
Thanks,

How to read files from current directory for applet

I have an applet that needs to read some audio files located in its current directory on the server and I just can't seem to figure it out...maybe I am being dumb...any help?

You can use the ListSorter File Adapter Configuration property to sort based on timestamp. Basically add the following property to the inbound JCA file:
<property name="ListSorter"
value="oracle.tip.adapter.file.inbound.listing.TimestampSorterAscending"/>
<property name="SingleThreadModel" value="true"/>
More info see section 4.2.6 in http://docs.oracle.com/cd/E23943_01/integration.1111/e10231/adptr_file.htm

How to read data from a file in OSB

hi guys,
Recently, I've got a problem with reading file from specific location. I've actually followed this post OSB 11g - Read or Poll File in OSB - Oracle Fusion Middleware Blog, and then
I know how to read a file. However, it does not as expected. Because, I've found no way to read data from the file. Therefore, no chance to manipulate the data like assigning to a variable, or extracting ....
Hence, is there any way to read data from file by using proxy service in OSB ??? No Java code ???
by the way, supposed that there is no way to read data from a file in OSB. So, What purposes will the way in the post above be used for?
Many thanks in advance
