Hi,

I need to read the database properties from a configurable properties file and set to the persistance.xml how can I do this for example if I need to change the database I need to go to persistance.xml and need to change the values, but I need like there should be a properties file in that I need to configure all the database properties and need to access those values to persistance.xml how can I do this?

Hi,

If I will copy the application url in the browser and paste it in a new browser, the request goes to --------- which servlet? How I can track the request? In web.xml <servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class> can I change this action servlet to any user defined servlet?

Thanks

Hi,

I need to create a datasource and need to use that every time.

Right now I am giving these properties in persistance.xml.

<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle9Dialect" />
<property name="hibernate.connection.driver_class" value="oracle.jdbc.driver.OracleDriver" />
<property name="hibernate.connection.username" value="pramod" />
<property name="hibernate.connection.password" value="pramod" />
<property name="hibernate.connection.url" value="jdbc racle:thin:@localhost:1521:localdb" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.format_sql" value="true" />
</properties>


and when ever I need to persist or remove I am doing this each and every time
EntityManagerFactory emf =Persistence.createEntityManagerFactory("usermgt");

Give me some sugessions so that I can use this commonly. I am using weblogic9.2.

Thanks,

Now I am having one more problem, if the Set is empty in the jsp I am getting empty select box. If the Set is empty I need to show as "No values".

How can I do this.

Thanks.
