Hi Oliver
Do you think it would be possible to pull XMLDescriptorsStore.java out of
the CVS, compile it, and then slot the class into the slide-stores.jar file?
I suppose that would just be a case of playing it by ear ;o)
I am really wary about trying to compile the whole thing from source... just
because it sounds like a nightmare!
I don't know if you are familiar with the exception below, thrown when I try
to start up using MySQLDescriptorsStore... To me it looks like a bug...
also (after the line I have drawn!), it throws this exception when I try to
view the store in the browser (which in turns shows a 500 error).
Is it significant that it talks of JDBCDescriptorsStore when I am actually
trying to use MySQLDescriptorsStore? Also, in the second error, it talks
about the com.mysql.blah.blah driver when I am actually using the
org.gjt.mm.blah.blah driver?
Maybe I should also get an updated version of JDBCDescriptorsStore from the
CVS?
Many thanks again
Stu

Subject: Re: weird error on file PUT
Hi Stuart,
sorry for causing confusion. You were right, XMLFileDescriptorsStore is
*not* available in Slide 1.0.16! It is in the CVS for 2.0 though.
Judging from my expericene 2.0 has better support than 1.x now and is
pretty stable. However, I could not find any evidence for an official
approach to make it a release soon. So, if you used it there would be
even less (even though there also is non for 1.0.16 either) guaranty
that everything works well.
In comparison with the JDBC stuff XMLFileDescriptorsStore probably has
some drawbacks. The two most obvious might be speed (altough I am not
quite sure about this, need to look at the implementation) and lack of
transactional control. I.e. in case of error you might get some XML
descriptor files half written or one written and one missing...
As to MemoryDescriptorsStore: I guess it is there for demonstration
purposes only. As XMLFileDescriptorsStore moved in only after 1.x it
seems there was no decent out-of-the-box descriptors store (at least not
with versioning).
Unfortunately, I can not help you with your exception as I have no
experience with 1.0.16. :(
Oliver
