Storing objects?
Hi again.
I am probably showing my ignorance of Java here, but is there a simple
way to store Java objects in an Axis webservice? I have a JDBC object
for connecting to the DB, but the overhead is high. I would like to be
able to store it between calls to speed up operation.
Thanks,
Justin

We're getting pretty far of topic here, but...
1) Use LDAP to perist java objects that are read more then written. LDAP
natively has 'java.schema' that can store any object that implements
'serializable' - such as a hashmap filled with strings.
However, you did say 'simple' ;-) .
2) Use a singleton. Just place a map or whatever as class variable. This can
be done in 5 minutes by any mid-level java developer. It has the
disadvantage, however, of losing your cached values on JVM restart. It also
has classloader side affects which can complicate things.
3) Use ehcache or whatever and let it handle the caching. It also has simple
file peristance that survives JVM restarts. Requires a day or two to get the
handle of it.
HTH,
Robert

Excellent thanks! I should have guessed someone would have already
thought of it ;-) .

then use a connection pool if you want to have a common db object
(http://jakarta.apache.org/commons/dbcp/)

Not session - global to the web service - every query should be able to
retrieve a common db object (under a lock).

do you mean a session object ?
