Problem with PostgresRDBMSAdapter

Hi all,
I am using Slide 2.1 and  trying to create store in PostgreSQL server 8.1.

Domain.xml:
<definition>
    <store name="PostgresStore">
          <nodestore 
classname="org.apache.slide.store.impl.rdbms.JDBCStore">
            <parameter 
name="adapter">org.apache.slide.store.impl.rdbms.PostgresRDBMSAdapter</parameter>
            <parameter name="driver">org.postgresql.Driver</parameter>
            <parameter 
name="url">jdbc:postgresql://127.0.0.1:5432/slide</parameter>
            <parameter name="user">slide</parameter>
            <parameter name="dbcpPooling">true</parameter>
            <parameter name="maxPooledConnections">10</parameter>
            <parameter name="isolation">SERIALIZABLE</parameter>
            <parameter name="compress">false</parameter>
      </nodestore>
        <contentstore>
        <reference store="nodestore" />
        </contentstore>
        <securitystore>
           <reference store="nodestore" />
        </securitystore>
      <lockstore>
            <reference store="nodestore" />
      </lockstore>
      <revisiondescriptorsstore>
            <reference store="nodestore" />
      </revisiondescriptorsstore>
      <revisiondescriptorstore>
            <reference store="nodestore" />
      </revisiondescriptorstore>
     </store>
     <scope match="/" store="PostgresStore"/>
    </definition>

web.xml:
<web-app>
  <filter>
    ...
    <resource-ref>
          <description>DB Connection</description>
          <res-ref-name>jdbc/slide</res-ref-name>
          <res-type>javax.sql.DataSource</res-type>
          <res-auth>Container</res-auth>
    </resource-ref>  
    ...


When starting Tomcat 5.5.12 I always get this exception:

org.apache.slide.common.ServiceAccessException: Service

There might be a problem in PostreSQL version because 
PostgresRDBMSAdapter is for Postgres 7.3/7.4. (as documentation says)
Could anyone help?

Thanks.
