Unarchive the .gzip files

[javvaji]

Hi Team,

I am having the .gzip files in FTP, we need to unarchive the files. I tried using tFileUnarchive component but i was getting the following error. Could any one help me on this.

Below is the error code

Exception in component tFileUnarchive_2

Hi,

Depending on your TOS version, GZIP format maybe not supported by tFileArchive/tFileUnarchive components.

Here is a workaround you may check for archinving https://www.linkedin.com/pulse/how-compressarchive-files-gzip-format-using-talend-open-vikram-takkar....

You'll probably be inspired for the reverse operation.

Thanks for the reply.

But in that link we don't have code to unarchive the .gzip files. we have only how to compress the file to .gzip format.

Thanks,

Bharath.

I didn't said this is the solution, I just said you'll probably be inspired by it.

See if you can use this java code to achieve your purpose in talend
