Hi , you guys
I am in a trouble with a NoClassDefFoundError when executing Poolman sample file.
(Poolman is a connection pool manager that is said to be a good one, isn't it)
My system is Compaq DL320,
OS : Redhat Linux 7.1
JDK : sun jdk1.3.1(j2se) + JDBC2 optional package ( jdbc2_0-stdext.jar -- CLASSPATH includes this)
POOL MANAGER : Poolman-2.0.4 ( I did installation as in README )
DB : Postgresql-7.1.2
and I use jdbc driver when I compiled postgresql. - postgresql.jar(CLASSPATH also includes this)
poolman sample file compiled fine but didn't execute
$ javac PoolManSample.java - OK
$ java PoolManSample "select * from test_table" "mydb"
Executing sample of SQLUtil executing SQL from the specified database:

In addition , my java VM doesn't find methods of JDBC2 classes. ( CLASSPATH includes all jar files)
but it find them well in Redhat Linux 7.0.
It makes me crazy. help !!!
ps. Is there anyone who use poolman with postgresql ?
