Hello All,

             I am developing an application which consists of several different modules pointing to the same database. I have configured the datasource in a JNDI file. I have done connection pooling in it like below:

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
  <local-tx-datasource>
    <jndi-name>jdbc/public_PostgreSQL</jndi-name>
        <connection-url>jdbc:postgresql://localhost/autohaul2</connection-url>
        <driver-class>org.postgresql.Driver</driver-class>
        <user-name>postgres</user-name>
        <password>stafona</password>
        <min-pool-size>5</min-pool-size>
        <max-pool-size>20</max-pool-size>
    <idle-timeout-minutes>5</idle-timeout-minutes>
  </local-tx-datasource>
</datasources>

Now my question is that whether this pool size will be for the whole container or each war file will have its own 20 pool size. For example, if I have the following modules:

Module A

Module B

Module C

Module D

and each module pointing to the same datasource in JNDI. So the whole system will have a max-pool-size=20 or 80?
