Problem with tFileList and tFileUnarchive

Anonymous — Sat, 16 Nov 2024 14:33:00 GMT

Within a java project,
I'm trying to unzip all files in a given directory. I can't make it work: (same problem as https://community.talend.com/t5/Archive/problem-with-tFileUnarchive/td-p/63201, but with java), I still have a java exception:
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 org.apache.tools.zip.ZipFile.populateFromCentralDirectory(ZipFile.java:243)
at org.apache.tools.zip.ZipFile.<init>(ZipFile.java:142)

at proto.perfweb.PERFWEB.runJob(PERFWEB.java:413)
at proto.perfweb.PERFWEB.main(PERFWEB.java:360)
Is it a bug ? Here there any other way to do it ?
Please find the détails in the images below

Which version of TOS did you use? I have tested this problem on my computer and it runs fine.
My project: windowXP, TOS2.2.0M2, Java
I unzip the .zip files in my project. please see the screenshots:

Thank you for your answer.
Indeed, if I replace the .gz file (created with linux) by .zip file (created with windows), then it works
However, its is strange:

file.zip-> tFileUnarchive -> OK
file.gz -> tFileUnarchive -> OK
dir/*gz -> tFileList -> tFileUnarchive -> KO
dir/*zip -> tFileList -> tFileUnarchive -> OK
why do the unarchive works with just one gz file but not with the filelist ?
I've tried every latest version of TOS
Thank you for your help

Hi Bobby
It is a bug from the component. You can see it here: http://talendforge.org/bugs/view.php?id=2103
it will unzip the file in zip by default
file.gz -> tFileUnarchive -> OK,

code:
java.util.zip.GZIPInputStream zip_tFileUnarchive_1 = new java.util.zip.GZIPInputStream(
new java.io.FileInputStream(new java.io.File(
zipFileURL_tFileUnarchive_1)));

file.gz -> tFileList -> tFileUnarchive -> KO

code:
String zipFileURL_tFileUnarchive_1 = ((String) globalMap
.get("tFileList_1_CURRENT_FILEPATH"));
