Hi Ajs6f

Thanks for including me in the conversation, but I have to confess I've 
never looked at java classes (I only use command line tools).

Hi Adam,

I haven’t seen that error. What I’ve done in the past is to replace the 
jena-text doc file with the new contents in Eclipse in an SVN checkout of the 
jena-doc-site and then committed.

I can definitely do that (and will when we're happy with the patch), but see 
below.


Out of curiosity when is it necessary to use the

 [] ja:loadClass "org.apache.jena.tdb.TDB” .

and

[] ja:loadClass   "org.apache.jena.query.text.TextQuery” .

? I do not use them in the config when running fuseki war in tomcat.

I have no idea whatsoever! :grin: I wouldn't have thought them needed either.

Vincent-- any comment?
