Thanks for your inputs in advance.

In .NET below configuration is used to specifies that the default credentials for a host are used to access the web proxy.

On executing the below code adding null (reference) to the String content. Appreciate your comments on the below.

public class Test{     public static void main(String []args){              String s=null;                s=s+"a";                System.out.println(s);                s=s+null;                System.out.println(s);     } }

Output
nulla
nullanull

As mentioned in the Spring Framework documentation:Spring 2.5 Documentation

Specifying the target bean by using the 'parent' attribute allows a reference to be created to a bean which is in a parent container of the current container. The value of the 'parent' attribute may be the same as either the 'id' attribute of the target bean, or one of the values in the 'name' attribute of the target bean, and the target bean must be in a parent container to the current one. The main use of this bean reference variant is when you have a hierarchy of containers and you want to wrap an existing bean in a parent container with some sort of proxy which will have the same name as the parent bean.
<!-- in the parent context --> <bean id="accountService" class="com.foo.SimpleAccountService"> <!-- insert dependencies as required as here --> </bean>
<!-- in the child (descendant) context --> <bean id="accountService" <-- notice that the name of this bean is the same as the name of the 'parent' bean class="org.springframework.aop.framework.ProxyFactoryBean"> <property name="target"> <ref parent="accountService"/> <-- notice how we refer to the parent bean </property> <!-- insert other configuration and dependencies as required as here --> </bean>
Appreciate, your help to understand the parent container and current container on the above context.

Resolved the issue with the following modification in the source code.

Form Bean (UserForm)

private String dob; private Date dobdt; public String getDob() { return dob; } public void setDob(String dob) { this.dob = dob; setDobdt(dob); } public Date getDobdt() { return dobdt; } public void setDobdt(String dob) { java.text.DateFormat df = java.text.DateFormat.getDateInstance(java.text.DateFormat.SHORT); java.text.ParsePosition pos = new java.text.ParsePosition (0); java.sql.Date dobdt = new java.sql.Date(df.parse(dob,pos).getTime()); this.dobdt = dobdt; }

hbm file
<property column="DOB" name="dobdt" type="date"/>

Updated post with Exception.

JSP (User Reistration)
<td align="left"><label><strong class="userid-label">Date of Birth</strong></label></td> <td width="20%"><html:text property="dob" "/><html:errors property="dob" /></td>
Form Bean (UserForm)
private Date dob; public Date getDob() { return dob; } public void setDob(Date dob) { this.dob = dob; }

Service Layer (UserDTO)
A copy of Form Bean

Action Class (UserAction)
boolean resultSave=false; UserForm userForm = (UserForm) form; UserDTO userDTO = new UserDTO(); UserDAO userDAO = new UserDAO(); BeanUtils.copyProperties(userDTO, userForm); resultSave=userDAO.saveUserDetails(userDTO);
Service Class (UserDAO)
public boolean saveUserDetails(UserDTO userDTO) { boolean result=false; try{ session = HibernateSessionFactory.getSession(); session.beginTransaction(); session.save(userDTO); session.getTransaction().commit(); result=true; }catch (Exception e) { System.out.println("Exception Occured in UserDAO :: "+e); e.printStackTrace(); } return result; }
In backend (DB Table) the datatype of the dob is date.

hbm file
<property column="DOB" name="dob" type="date"/>

Such type of issues occur due to malformed source or request not reaching to the server.
Check the login page for any syntactical error.
Also check the web.xml for the url (the action you have specified in your login page) mapping.

Thanks Jeanne for making me know about another interesting feature of JDBC. If I am not wrong, I have to use Tomcat DBCP feature (by using the jars - commons-pool-x.x.x.jar and commons-dbcp-x.x.jar and getting an instance of the class BasicDataSource) for this purpose.

But still I am hunting for the answer with the JNDI setup.

In web application, we can connect to the database by supplying the configuration details in server.xml or context.xml. Is it possible to achive the same thing in a stand-alone application? I am getting the below exception while running an stand-alone application:
Cannot get connection: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

From the description it is clear that the configutarion detail need to be provided in the form of environment or system property or through the application resource file java.naming.factory.initial. Tried to get the solution in the web, but didn't got the result.
Kindly sugest.

Waiting for suggestions.........

By mistake, posted the topic in ORM instead of Struts. Gentle request to the Sheriffs and Bartenders to be kind move it to the Struts Forum.

My requirement is :
1. To display a default text in a textarea.
2. The default data has to be read from the ResourceBundle.
3. The data in the textarea cannot be edited.

It is possible to achieve the task by using <html:textarea>?

If yes, then how?

The code I am trying with is as follow:
UserRegistration.jsp
<tr> <td><bean:message key="lbl.Terms" /></td> <td><html:textarea altKey="msg.TermNCond" property="terms" /></td> </tr>

MessageResources.properties
lbl.Terms=Terms of Service msg.TermNCond=I accept the terms and conditions............

struts-config.xml
<struts-config> <form-beans> <form-bean name="UserRegistrationAF" type="com.myorg.form.UserRegistrationForm"> </form-bean> </form-beans> <action-mappings> <action path="/postRegistration" type="com.myorg.action.UserRegisterAction" name="UserRegistrationAF"> <forward name="success" path="/Success.jsp" /> </action> </action-mappings> <message-resources parameter="MessageResources" null="false" />

The JSP is successfully getting generated, but the default data is not getting displayed.

Suggestions will be appreciable.
