[resolved] Component to test if FTP folder exist?

Anonymous — Sat, 16 Nov 2024 12:57:57 GMT

Hello,
I am looking for a simple way to test if a ftp folder exists.
I have tested with tFTPFileExists and tFTPFileList, but no chance. When folder does not exists a java exception is thrown.
How can I do a such test with Talend?
I am working in TOS 4.1.0M3
Thanks for helping,
Eduard

Take off die on error.
Then it will be:
tFTPGet --on Subjob Failure--> Desired Component
Look at the images below to help you.

If you want it to loop the job again until the Directory exists ask me and I will show you another example.

Hi Brandon,
In my very first approach I wanted to do it "more soft" : without raising any exception.
If there isn't any other way I will do it like this, and try to workaround the exception with logging set up.
Many thanks for your help,
Eduard

Try this way

tJava Code:

context.test = 
((String)globalMap.get("tFTPGet_1_ERROR_MESSAGE")).equals("test: No such file or directory") ? "yes" : "no";

if statements code:

context.test == "yes"
context.test == "no"

As I don't think there is a more soft way, that I know of atleast i may be mistaken

Hi Brandon,

I saw your post and looking for a solution to check if the file exists on ftp server using tftpfileexist. If not it should check again every 1 minute and kick the job once the file is found and send a notification once the process is done and loop back to check for the next file. If the file is not found after certain period it should send a notification and loop again to check if the file is present. How to achieve this? A detail job would be helpful.

Thanks
