Pallavi Welcome to Java ranch!

Please read this http://www.differencebetween.net/technology/difference-between-jsp-and-html/

I have the tables as in the screenshot above

Class are written as below

@Entity public class Object { @Id private int id; private String name; @OneToMany(mappedBy="object",fetch=FetchType.LAZY) private List<ObjectAttribute> attrubuteList; } @Entity public class ObjectAttribute { @Id private int id; @Id @ManyToOne @JoinColumn(name="objectId") private Object object; private String name; } @Entity public class Filter { @Id private int filterId; @ManyToOne @JoinColumn(name="ObjectId") private Object object; private String filterName; @OneToMany(mappedBy="filter") private Set<FilterAttribute> filterValues; } @Entity public class FilterAttribute implements Serializable { @Id private int filterAttrId; @Id @ManyToOne @JoinColumn(name="objectId") private Object object; @Id @ManyToOne @JoinColumn(name="filterId") private Filter filter; @Id @ManyToOne @JoinColumn(name="attributeId") private ObjectAttribute attribute; private String value; }
Note not added getter and setters

and test code as below

List<Object> list = sess.createCriteria(Object.class).list(); for(Object ob: list) { System.out.println("Object name : "+ ob.getName()); List<ObjectAttribute> attList = ob.getAttrubuteList(); for (Iterator iterator = attList.iterator(); iterator.hasNext();) { ObjectAttribute objectAttribute = (ObjectAttribute) iterator .next(); System.out.println(objectAttribute.getName()); } }

I am getting the below exception
Caused by: org.hibernate.AnnotationException: A Foreign key refering test.rest.ObjectAttribute from test.rest.FilterAttribute has the wrong number of column. should be 2 at org.hibernate.cfg.annotations.TableBinder.bindFk(TableBinder.java:450)

i came to know i should have the 2 attributes in FilterAttribute class to hold the composite key.. But how can we do that?

Hi all

i am learning hibernate and spring
i have made a one-to-one mapping for Employee and Address tables,

where Employee and Address are different entity as below

import java.io.Serializable; import javax.persistence.CascadeType; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.OneToOne; import javax.persistence.Table; import javax.persistence.UniqueConstraint; @Table(name="EMPLOYEE", uniqueConstraints = { @UniqueConstraint(columnNames = "ID"), @UniqueConstraint(columnNames = "EMAIL") }) @Entity public class EmployeeEntity implements Serializable { private static final long serialVersionUID = -1798070786993154676L; @Id @Column(name="ID") @GeneratedValue private Integer id; @Column(name="FIRSTNAME") private String firstname; @Column(name="LASTNAME") private String lastname; @Column(name="EMAIL") private String email; @Column(name="TELEPHONE") private String telephone; @OneToOne(mappedBy="employee", cascade=CascadeType.ALL) private AddressEntity adress; //Add setters and getters

and the Address as below
@Table(name = "ADDRESS", uniqueConstraints = { @UniqueConstraint(columnNames = "ID")}) @Entity public class AddressEntity implements Serializable { private static final long serialVersionUID = -6790693372846798580L; @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "ID", unique = true, nullable = false) private Integer addressID; @Column(name = "STREETADDRESS") private String streetaddress; @Column(name = "CITY") private String city; @Column(name = "STATE") private String state; @Column(name = "ZIPCODE") private String zipcode; @OneToOne @PrimaryKeyJoinColumn private EmployeeEntity employee;

And the JSP as below

Sorry i dont know how to format the JSP
<form:form method="post" action="add" commandName="employee"> <table> <tr> <td><form:label path="firstname"><spring:message code="label.firstname"/></form:label></td> <td><form:input path="firstname" /></td> </tr> <tr> <td><form:label path="lastname"><spring:message code="label.lastname"/></form:label></td> <td><form:input path="lastname" /></td> </tr> <tr> <td><form:label path="streetaddress"><spring:message code="label.streetaddress"/></form:label></td> <td><form:input path="streetaddress" /></td> </tr> <tr> <td><form:label path="city"><spring:message code="label.city"/></form:label></td> <td><form:input path="city" /></td> </tr> <tr> <td><form:label path="state"><spring:message code="label.state"/></form:label></td> <td><form:input path="state" /></td> </tr> <tr> <td><form:label path="zipcode"><spring:message code="label.zipcode"/></form:label></td> <td><form:input path="zipcode" /></td> </tr> <tr> <td><form:label path="email"><spring:message code="label.email"/></form:label></td> <td><form:input path="email" /></td> </tr> <tr> <td><form:label path="telephone"><spring:message code="label.telephone"/></form:label></td> <td><form:input path="telephone" /></td> </tr> <tr> <td > <input type="submit" value="<spring:message code="label.add"/>"/> </td> </tr> </table> </form:form>


Problem is if submit only the employee related data works fine
if i add the address details in the JSP and submit it throws exception

org.springframework.beans.NotReadablePropertyException: Invalid property 'streetaddress' of bean class [com.employee.entity.EmployeeEntity]: Bean property 'streetaddress' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?
at org.springframework.beans.BeanWrapperImpl.getPropertyValue(BeanWrapperImpl.java:707)
at org.springframework.beans.BeanWrapperImpl.getPropertyValue(BeanWrapperImpl.java:699)


How to fix this.. which setter need to add in JSP

Hi all

I need a idea for getting map data from other browser window.

my use case as below:
1: User click on the link which open the map in new tab or new window.
2: user will mark the point on the map.
3: I need to get that point and other details in the first tab or window.

API for getting data from the map is provided by the google MAP
But how to get the map object which is in the different window.


Please suggest how i can achive this

Thanks

if you are using eclipse, then just Ctrl+Click on the Class from your Code, which will show the jar

@Winston

Sorry for that.

i was checking Static code check for Security Problems

I have found that i am useing the method

loginDetails.getPassword();

Which is changed to diffrent name.

For the 2nd error
InetAddress.getByName(strIPAddress).getAddress();

This API is from JDK so we need not to fix.

So problem solved

Hi all

I have to fix some 2 fortify errors
1. Password management

i am reading username and passowrd from the Object and keeping in Property file.
it is giving error

Like
Properties prop = new Properties(); Object loginDetails = Object.getLoginDetails(); prop.setProperty("Username",loginDetails.getUsername()); prop.setProperty("Password",loginDetails.getPassword());
2. Missued Authentication

InetAddress.getByName(strIPAddress).getAddress();
Where strIPAddress is argument to this method.
