Unresolvable NoSuchMethodError

[Michel Jung <mi...@gmail.com>]

Hi!

I'm trying to read an XLSX file. I added all the libraries to the projekt
and to it's build-/classpath. The program is running on a tomcat.
I run into an exception which I couldn't solve for hours now. This is the
Code:

68    InputStream inputStream = new FileInputStream( file );
69
70    Workbook workBook = WorkbookFactory.create( inputStream );

This is the stacktrace:

java.lang.NoSuchMethodError:

My lib contains:

Any help would be appreciated.
