I've looked through a number of the UnsatisfiedLinkError threads on here and nothing seems to quite fit my problem.

I am trying to get this api working: 7ZipBind

However I am having an issue, and cant get the thing to work. I am running some of its example code from the commandline like so:

C:>java -classpath "/sevenzipTest.jar;/sevenzipjbinding-AllWindows.jar;\sevenzipjbinding.jar" com.poc.sevenzip.SevenZipSimple c:\archive\test.zip

However when I try to run it I get the error: 

Exception in thread "main" java.lang.UnsatisfiedLinkError: D:\Users\XXXX\AppData\Local\Temp\SevenZipJBinding-9640553\lib7-Zip-JBinding.dll: Can't

        at com.poc.sevenzip.SevenZipSimple.main(SevenZipSimple.java:64

What I am confused about, is why it says it cant locate the libraries (dll files), when the libraries are stored within the <file_path>/sevenzipjbinding-AllWindows.jar file... I am obviously not doing something correct here, and was hoping some1 can give me some pointers.

Cheers

  • As far as I know, it is not possible to load the dll directly from the jar-archive...you need to extract them first. http://stackoverflow.com/questions/1611357/how-to-make-a-jar-file-that-include-dll-files – HectorLector May 10 '12 at 13:49

The following instructions are for Windows x86 and 7 Zip JBinding version 4.65-1.05 RC. Download the following DLLs.

Add the DLLs into the Windows-x86 directory in sevenzipjbinding-AllPlatforms.jar. Then append the following lines to sevenzipjbinding-lib.properties in the Windows-x86 directory in the jar.

sevenzipjbinding.libname.3=gpsvc.dll
sevenzipjbinding.libname.4=libgcc_s_dw2-1.dll
sevenzipjbinding.libname.5=libstdc++-6.dll
sevenzipjbinding.libname.6=sysntfy.dll

Instead of modifying the jar file, one could put the DLLs in the PATH (not classpath).

In order to figure this out, I extracted lib7-Zip-JBinding.dll from sevenzipjbinding-AllPlatforms.jar. I then opened the file in Dependency Walker.
