Not that I know of. Google is a pretty good alternative as it has
indexed all the archive - just add +"biojava-l" to the beginning of your

Yes, there is, but it's not very good and will soon be deprecated.
Programs really should know what they are expecting to read and complain
if they don't find it.

Depends on the format. In the case of GenBank and EMBL, they are very
stringent about indent sizes because the parsers rely on indents to
identify sections of the files. Different size indents mean different
things. However elsewhere extra spaces should not be a problem. I
haven't really tried that hard yet to break them so don't know exactly.
Incidentally the org.biojavax packages provide a whole new set of
parsers and an updated object model for storing the information that has
been loaded. See the DocBook-format documentation under
"docs/docbook/BioJavaX.xml" in the biojava-live CVS repository. The
comments above refer to these new parsers. The old (1.4) ones really
should not be relied upon for detailed work.

It can only read alignments. As yet it cannot generate any itself.

Not that I know of. Blast works very well as an external process fired
off by Java and with standard output piped directly back into Java. I
can't see the reason why you'd want to re-implement it unless some
significant change to the algorithm made it necessary. ClustalW

For now, send it to this list.
Thanks for the interest anyhow - sorry I couldn't answer all your
questions at once! I can definitely recommend investigating the newer
bits of BioJava though (BioJavaX), although they won't officially be
part of it until the 1.5 release, and no date has been set for that yet.
