Tomcat 5.5 Cannot create PoolableConnectionFactory

[jcbf <j....@schmitt-elevadores.com>]

After successfuly connecting to the databases through JDBC drivers over a
proxool pool, 
I tried to configure JNDI datasources so that my dbforms webapp could
cleanly call
and implement connections through the JNDI space.

In tomcat 5.5 the web context file looks like :

…
<Resource
    name="jdbc/DB1"
    type="javax.sql.DataSource"
    driverClassName="com.informix.jdbc.IfxDriver"
    password="pwd"
    maxIdle="2"
    maxWait="5000"
    username="usr"
    url="jdbc:informix-sqli://host:1234/db1:INFORMIXSERVER=svr"
    maxActive="16"
    removeAbandoned="true"
    removeAbandonedTimeout="60"
    />
…

I have two more DBs configured the same way in the same file.

The web.xml looks like :

<resource-ref>
        <description>DB1 Connector</description>
        <res-ref-name>jdbc/DB1</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
  </resource-ref>
  <resource-ref>
        <description>DB2 Connector</description>
        <res-ref-name>jdbc/DB2l</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
  </resource-ref>
  <resource-ref>
        <description>DB3 Connector</description>
        <res-ref-name>jdbc/DB3</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
  </resource-ref>
…

The dbforms config file looks like this :

…
          <dbconnection
                                id = "db1"
                                name = "java:comp/env/jdbc/DB1"
                                isJndi = "true"
                                default = "true"
                 />

                 <dbconnection
                                id = "db2"
                                name = "java:comp/env/jdbc/DB2"
                                isJndi = "true"
                 />

                 <dbconnection
                                id = "db3"
                                name = "java:comp/env/jdbc/DB3"
                                isJndi = "true"
                 />
…

The web starts up ok ,except when I get into a JSP with data from those
connections where it crashes stating :

java.lang.IllegalArgumentException: JDBC-Troubles:  
was not able to create connection from DbConnection = id=db1

and tomcat sigs :

ERROR-[10.08.2006
14:25:14]-[http-9080-Processor25]-[org.dbforms.config.DbConnection.getConnec
tionFromJNDI
(DbConnection.java:625)]-::getConnectionFromJNDI - exception:

 Cannot create PoolableConnectionFactory (Database not found or no system
permission.)
        at
org.apache.tomcat.dbcp.dbcp.BasicDataSource.createDataSource(BasicDataSource
.java:855)
…

Any insight ?

Thanks in advance.
