JAI vendorname == null

Question

So I finished coding my application to rotate TIFF images which required JAI to manipulate the TIFFs.

It works fine when working under Eclipse, but whenever I build

DISCLAIMER

The issue that I was having was slightly different, I was getting the "ClassNotFound" error while trying to run a compiled jar file. I happened upon this SO question while researching, so for others who followed the same trail that I did, here you go.

Possible Solution to ClassNotFound Error

To those who may find this question later on, if nothing else seems to work, You could try using the Apache Shader plugin for Maven. Here is some more information on it.

I'm not experienced enough to be able to tell you how it does it, but Apache Shader packages all the used dependencies in your project into the final jar file, so that all the dependencies are included in the META-INF folder when it's built. This increases the size of the jar file (depending on how many libraries you used in your project), but also seems to fix the jar not being able to find classes from outside libraries that are used.

To use the Shader plugin, add the following to your POM. I included it after the dependencies tag and before the properties tag.

    
        
            org.apache.maven.plugins
            maven-shade-plugin
            2.4.3
            
                
                    package
                    
                        shade
                    
                    
                        
                            
                                *:*
                                
                                    META-INF/*.SF
                                    META-INF/*.DSA
                                    META-INF/*.RSA
                                
                            
                        
                        
                            
                                
                                    com.package.name.className
                                    1
                                
                            
                        
                    
                
            
        
    

NOTE: Make sure you change the package and class name to reflect your project's package and class names.
