I wrote a pojo class say it Employee.java

package org.emp;
public class Employee {

private String empid;

private String empName;

private String address;

public String getAddress() {
return address;
}

public void setAddress(String address) {
this.address = address;
}

public String getEmpid() {
return empid;
}

public void setEmpid(String empid) {
this.empid = empid;
}

public String getEmpName() {
return empName;
}

public void setEmpName(String empName) {
this.empName = empName;
}
}

Now i want to generate hbm file for this pojo file.

how??? using Xdoclet?

Thanks in advance.....




Hi All
I have a hql query , when ever i iam getting 400 -500 records it is taking 3-4 sec. but when iam getting around 5000 record it is taking more time around 3 min in local system.

the method is
public List getAllSourcedCandiadtes(String startingDate, String endingDate) {

return (List) getHibernateTemplate().find(

"select distinct prospectiveCandidates from ProspectiveCandidates prospectiveCandidates where prospectiveCandidates.appliedDate between '" + startingDate + "' and '" + endingDate + "' and (prospectiveCandidates.sourceName != 'candidate' ) and (prospectiveCandidates.sourceResume !=null )");
}

the query is working fine but I want to improve the performance, even i tried using criteria API
Criteria crit = session.createCriteria(ProspectiveCandidates.class)
.add(Expression.between("appliedDate", new Date(startDate.getTime()),new Date(endDate.getTime())));

crit.add(Restrictions.and(Restrictions.ne("sourceName","candidate"), Restrictions.isNotNull("sourceResume")));

List abcd= crit.list();

return abcd;

I am able to get records with criteria API but iam not able to improve the performance.
please suggest me ................

I got ajsp with two button which calls struts action class methods(ShowEntries).

In struts action class i got a method called
ShowEntries(ActionMapping................){

return mapping.findForward("xxxxx");
}


In Jsp, when First button is clicked it needs to displays information in display tags and second button needs to display data in Html page. but Both are pointed to ShowEntries method of Action classes. we have only one forward for one action. without repetition of code how can i access. or is there any way to keep to two return find.forwards.

In struts we place key and value information in properties file for displaying message.

in java page

ActionMessage msg = new ActionMessage("errorupload.empty");
exMsg.add("message1", msg);
saveErrors(request, exMsg);
return mapping.findForward("entersheet");

in application.properties
errorupload.empty=please enter valid sheet.

whenever any thing goes wrong i get the message please enter valid sheet.
I want to add dynamic information to these messages. like it should take some value from java page and display dynamically that information along with message.
