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?
==================
thanks for your help.
