Hi All,

Can I print document without view the "Printing Options" window on Windows and Linux. What exactly I want is to print to virtual printer (to image instead of paper) without viewing that window, so that when I press "Print" the image is saved directly to a specified folder.

Can anybody give some hint?

Thank you.

Thank you.

Hello,

I have a problem. For every day of a month (lets say February) I want to show records from a PhoneCall table stored in a MySQL database.
The PhoneCall table looks like this:

Record No. Date PhoneNumber
------------- --------------------- -----------------
1 2010-02-01 10:04 491111111
2 2010-02-03 08:35 492222222
3 2010-02-03 08:40 491234567

You see for the 2nd February NO phone calls are in the table.
Now I want to create a query that shows the phone calls for EVERY day of February 2005:

Date No Of Calls
--------- ----------------
2005-02-01 1
2005-02-02 0
2005-02-03 2

But if I do a query like:

select Date, count(Date) As No Of Calls
from PhoneCalls
where Date >= '2005-02-01' and Date <= '2005-02-28'
group by Date

I don't get a record/result for the 2nd February.

So I wanted to use a LEFT JOIN, but how to create the Date-table that holds all days of current month?


So how can I solve this problem?

Any ideas are appreciated?

Hi,

I have a checkboxlist in a jsp page, the checkboxlist read list of project names from the action so that the user can check any group of them.
What I want is when the user enter again he will see the items he choose before "checked".

The action class{

public class GetProjects extends AbstractAction { private List projects; public String execute() { projects = ... return SUCCESS; } public List getProjects() { return projects; } public void setProjects(List projects) { this.projects = projects; } }



This the piece of jsp:

<s:checkboxlist label="Projects" name="projectIds" list="allProjects" listKey="id" listValue="name" required="false" value="[b]??????[/b]" />


Thank you.

Hi All,

I work on an application that connect to database by hibernate (I use annotations). I have 2 entities (Department and Employee). Of course the Employee has one Department but the Department has many employees.

What I want is to be able to delete some Department without delete its Employees. (When deleting Department the hibernate should delete constraints that link some Employees to it without deleting the Employees).

Here are the classes:

*** This is the Department class:

@Entity public class Department { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "ID",updatable=true) private long id; @Column(name = "TITLE", length = 100, nullable = false) private String name; @OneToMany(mappedBy = "department") private List<Employee> employees; public long getId() { return id; } public void setId(long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public List<Employee> getEmployees() { return employees; } public void setEmployees(List<Employee> employees) { this.employees = employees; } }



*** This is the Employee class:

@Entity public class Employee { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "ID") private long id; @Column(name= "NAME", length = 100, nullable = false) private String name; @ManyToOne() private Department department; public long getId() { return id; } public void setId(long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Department getDepartment() { return department; } public void setDepartment(Department department) { this.department = department; } public void setProjects(List<Project> projects) { this.projects = projects; } }


Any help please.

Thank you.
