Bug or incompatibility?
hi commons-users
i just started an eclipse-project in which i use commons-dbcp, and pool
to establish a db-connection-pool. by the way i use jTDS as driver for
mssqlserver.
if i run my code i get a java.lang.NoClassDefFoundError:
org/apache/commons/collections/CursorableLinkedList
when i add the actual commons-collections-3.1 to my lib-dir i get the
same error. if i take the collections-jar from tomcat 5, the error is gone.
1. question: is collections needed to work with dbcp and pool?
2. question: is the above a bug or an incompatibility?
greetings
stefan

org/apache/commons/collections/CursorableLinkedList was deprecated in
collections 3.0/3.1 but still exists, so you shouldn't get a
NoClassDefFoundError. Hopefully the dbcp/pool developers can comment more
about the dependency.

hi dirk
i get all the jars (dbcp, collections, pool) from the binary release
page of apache commons. i took the older collections from the tomcat-5-jars
according to stephens answer, the class
"org/apache/commons/collections/CursorableLinkedList" will be deprecated
in future collections-releases.
perhaps there is an eclipse-setting that ignores deprecated classes in jars?
but well, if this happens, how can we then use dbcp and pool which need
this class???
greetings

A binary incompatibility maybe.
I just checked and commons-collections-3.1 and it still has the
required classes. (commons-pools compiles)
Where did you get all your jars? (zip/tar.gz download, from
maven/ibiblio, build by yourself?)
