B4J Question Error when unzipping Zip Files

[potman100]

Hi

Wonder if anyone can help with a problem I am having with extracting Zip files, the zip file contains 1 file and when I run the following command

Dim zip As ABZipUnzip

zip.ABUnzip(File.DirApp & "\tmp\" & "temp.zip",  File.DirApp & "\tmp\")

using ABZipUnzip library I get the following errors :

The zip file extracts fine in Winzip inder windows 7.

My java version is Version 7 Update 45 / jdk1.7.0_45

I have also attached the zip file I am trying to extract.

Thanks

Is this the actual content of this zip file:

?

Hi Erel

Yes that is correct, I believe that the file in the zip is created by an automated process.

You may try archiver lib, which works for b4j zip and unzip.

Hi Billzhan

Thanks for the suggestion, but I had already tried the Archiver library before posting, it produces a similar error.

I think its more of a Java issue ?

Yes I can see the same thing here.

I think it's caused by the unusual file name.
When I the file name is same as before, exception thrown.
When I re name file to c.nzb and zip it, the archiver lib works

 

[potman100]

Yes, I had also noticed that, but the file name is legal as in terms of windows allowed file names.

The problem is as these files appear to be auto generated, they all are very similar to the one I have posted.

Looking on line this seems to be an issue with the Java 7 sdk / runtime.
