    Hypersonic DB - Jboss AS 6.0.M1- Datasource/Tables unaccessible from JSP pages

    venkatesan pillai Newbie

      Hello,

       

      I want to acces Hypersonic database localDB (table name "Customer") from my JSP page.

       

      I am missing some configuration information while seting up a database in Hypersonic/JBoss AS 6.0.

       

      Due to this I am unable to access the tables from my JSP page.

       

      Can someone help me to fix this and tell me where should I set things right?

       

      Thanks for your kind attention.....

       

      Regards,

      Venkatesan  D. Pillai

       

      PS: I paste herewith the JBOSS console error, hsqldb-ds.xml for your info. pls.

      3) Some issues in hsqldb-ds.xml configuration

      ########################################

         <mbean code="org.jboss.jdbc.HypersonicDatabase"

           name="jboss:service=Hypersonic">

         <attribute name="Port">       
                <value-factory bean="ServiceBindingManager" method="getIntBinding"
                  parameter="jboss:service=Hypersonic"/>
            </attribute>
            <attribute name="BindAddress">       
               <value-factory bean="ServiceBindingManager" method="getStringBinding"
                  parameter="jboss:service=Hypersonic"/>
            </attribute>

       

      "Port, BindAddress" attributes create error in JBossAS console if I leave it as is with VALUE-FACTORY tag. So I replace them with 1701, localhost.

       

      Is this shortccut acceptable?
