Hi -
 
The missing JAR file is the jakarta regular expression library (required in biojava1.3 
not required in biojava-live). You can get it from the biojava download page.

        Hi, Good day!
           I got a "NoClassDefFound" exception when I call:
        
                db = SeqIOTools.readFasta(is,alpha);

                //get a sequenceDB of all sequences in the file
                db = SeqIOTools.readFasta(is,alpha);
                .....

           My observation is the missing class is from xerces.jar.  I appreciate your
