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

dvenkatesan Apr 10, 2010 12:16 AM

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">

"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.
