Hello,
I've tried to use DBTags in combination with Resin 2.0.x
One problem I had was that when more then one result was in the resultset I
would get a null pointer exception:
null
java.lang.NullPointerException

org.apache.taglibs.dbtags.resultset.BaseGetterTag.getColumnNumber(BaseGetter

After downloading the source I saw that in BaseGetterTag you have the
variable _name.
The first time this _name is the column name I'm requesting results from.
(in the sql query)
For the second element in the results of the sql query ... _name has become
null.
Removing _name = null in the release() method fixes this error. (but maybe
will introduce other errors)
I've not yet found why and where this _name variable is set and why it is
set the first time and not set the second time.
Anybody has a clue ? (I'm not familiar with the DBTags source code, but
probably some are :))
