Re: [Geotools-gt2-users] Reading a GeoTiff from an InputStream?

[Jon B. <jbr...@gl...>]

Hi,

I was trying this:

reader = new GeoTiffReader(this.getInputStream());
GridCoverage2D image = (GridCoverage2D)reader.read(null);

However, I get a number of exceptions:

Error while parsing JAI registry file
"/D:/geotools/2.5.x/modules/library/coverage/target/classes/META-INF/registryFile.jai"
:
