[resolved] Does tFileUnarchive support 7z files ? [Negative seek offset] Error

[ffwrude]

Hi,
Dunno if it's worth oppening a "bugtracker" but i have an issue with using the tFileUnarchive component with 7z file.
When trying to unzip in TIS here is what i got :

 connecting to socket on port 3438
 connected
Processing archive d:/file.7z, please wait...
Exception in component tFileUnarchive_1
java.io.IOException: Negative seek offset
	at java.io.RandomAccessFile.seek(Native Method)
	at org.apache.tools.zip.ZipFile.positionAtCentralDirectory(ZipFile.java:365)

	at informix_exapaq.ftp_0_1.ftp.main(ftp.java:615)

I can unzip the file in windows with winrar without problem. I had no trouble with ZIP files with this procedure.
Any idea ?

Hi
Which version of TIS/TOS are you using? You are using tFileUnarchive to unzip a archive file zipped by 7z, right?

I do.
TIS 4.2.2

Hi
It does not support the extension ".7z", you need to zip the file with ".zip" and it should be ok.

Oh ok.
Because the french tooltip is saying : "Extract data from a file of any type" So i thought 7z was supported.
Thank you.

hi,
for a project, we have to get an archive file by ftp.
this archive was zipped by 7z and had the extension ".7z".
do you have any idea for how to unzip it thanks to talend EE 4.2.2?
we cannot zip it with ".zip". we can just exploite the file.

Hi
Yes, it is possible, you have to install 7-zip on the machine and use tSystem component to call the command to unzip the archive file. for example:
"cmd /c 7z e d:/file/in.7z oc:/file/"
d:file/in.7z the path of archive file
c:/file/ the path of target directory.
