java.lang.NoClassDefFoundError: com/enterprisedt/net/ftp/FTPException

Anonymous — Thu, 23 Jul 2015 14:39:54 GMT

Hi all
I am trying to set up a tFTPConnection, with FTPS Support, using the below setup

However I am left with the following error when I try and run it:

Any ideas what is wrong?
I am running this:
"Talend Open Studio for Data Integration"
Version: 5.6.1
Build id: V5.6.1_20141207_1530
On a windows 8 64bit machine.

Do you have a file called edtftpj.jar (or similar) in your \Studio\configuration\lib\java folder?

Are you running it in the Studio when you get this error or as a standalone job?

For some reason it is not displaying my screenshots.....
This is the error I receive:
"com.enterprisedt cannot be resolved to a type"

To publish a screenshot in this Forum, you can use either of these boxes below: one is to drop a file from your file system, the other one is to paste the image from your clipboard. Let me know if this is what you've done and still had an issue getting your screenshots displayed or if you used another way, such as the upload button from the toolbar?
Can you try to paste your FTP component configuration please?
Can you check whether the Module view suggests you to download a jar?
Can you access your FTP outside Talend (just in case the exception would be totally misleading).

I am trying to attach a screenshot, it shows that it is displaying in the text box, but then when I hit "Submit" the image does not appear.
(Am attempting to upload with the "Upload" button now.

This is the error I now receive:

When you look at your Job design, you will notice in the bottom left there are at least 2 tabs (depending on the environment). These tabs say "Designer" and "Code". Can you click on the "Code" one and let us know if there are any red markers that appear on the right hand side of the code window once the code has generated. If there are, can you find the code that they relate to. This sounds like a classpath issue that may actually be a Talend bug.

I get an error here now:

} catch (com.enterprisedt.net.ftp.FTPException e) {
							globalMap.put("tFTPRename_1_CURRENT_STATUS",
									"File rename fail.");
							throw e;
						}

Telling me that com.enterprisedt cannot be resolved to a type.
There is not a file to be renamed currently (I am setting up the job to work), but I have email alerts set up if there is no file etc, but this is killing the job.

I think your install might be corrupted possibly. Do you have a folder called \plugins\org.talend.libraries.ftp_5.6.1.20141207_1530\lib
with the following files inside...
commons-net-3.3.jar
edtftpj.jar
ftp4j-1.7.2.jar
jsch-0.1.51.jar
If the answer is no, that is your problem. You should be able to get these Jars from teh first folder I asked you to check earlier. If the folder does not exist, simply create it and add the files. You will then need to restart your Talend Studio.

Hang on, you are using 5.6.1, correct? I ask as you have just told me that the folder in which you have those files is a 5.5.1 folder. Have you upgraded from 5.5.1? Do you have both version running side by side? If so, that is fine, but you will need this folder ....
org.talend.libraries.ftp_5.6.1.20141207_1530

I do not have that in this folder:
C:\Talend\TOS_DI-20141207_1530-V5.6.1\workspace\.metadata\.plugins\

Do I literally just take the four files from my previous folder, and put them in a folder named:
org.talend.libraries.ftp_5.6.1.20141207_1530

Many thanks for all your help

It's not a folder inside your workspace, it is a folder inside your main installation. Mine is here...
\Talend-Studio-20141207_1530-V5.6.1\plugins\org.talend.libraries.ftp_5.6.1.20141207_1530\lib
If you don't have that folder, I would take a back up of your jobs and reinstall.

Thank you for your help.
I will export all my jobs, uninstall/reinstall Talend and start over again
Will let you know, cheers!

Yes, please post here again for your FTP jar issue. On my end, I have passed on the image upload issue to the web dev team to investigate it. Cheers

Esabot,
I believe the issue with posting images is due to not having posted more than 10 posts. I recently set up a new user on here (this one) as my old one was linked to my old Talend work account. When I set that up I had to post 10 times before I could post images.
