Need to convert a long into a string, please

hi there
i need to convert a long into a string. can i just cast it like this:
(String)longNumber = some function that returns a long;

Why not just use Long.toString()? If you start with a long value, you can create a Long object and get it's value as a String.

Converting a long to a string (PLEASE HELP)

I am trying to convert a long to a string so that I can put it into a vector. I have this:
long fileSize = 0;
String fileModDate = null;
Vector fileList = new Vector();
~~~~~~~
File [] files = myDir.listFiles();
for (int i = 0; i<files.length; i++){
fileSize = files.length();
String s = fileSize.toString();
//do the same for the mod date
fileModDate = files[i].lastModified();
When i try this, i get an error that long can not be dereferenced. Can anyone please help?

There are two ways to solve this problem. You are trying to convert a primative type to a string without using its wrapper function (Long). So if you created a long variable as a (Long) object you could call its toString() method and this would work...
The other way is to simply use the static method in the String class valueOf(long) as follows:
String longString = String.valueOf(i);Hope this helps.

I need to insert an eof into a string

I am using RandomAccessFile and I need to insert an EOF into a String manually. Any tips on how to do this? Here is a snippet of the code.
origF.seek(0);
replacement = "The stuff I want in the file.";
replacement = replacement + ??????; //(to indicate an EOF for the file)
origF.writeBytes(replacement);
origF.close();

I found my way. Take a look in this piece of code.
    vlWrite.seek( vlPresentEntryPoint ); // position the file
    vlWrite.writeBytes( vpNewString );    // writes the new string
    vlWrite.writeBytes( vlSavedData );    // writes remaing file content
    vlWrite.setLength( vlFileLength );    // redifines file length
    vlWrite.close();I'm planning to share my code(s) in the forum. But me first make a concerning question. I'm new in Java and came to this forum to find and give help when I can. But, it is a forum where people wants to help and share or what ?????

Convert an Object into a String

Good day to everyone. I am trying to do a little coding in which a user will input his desired username. I want to check the database if the desired username of the current user is existing, so there'll be no duplication. I'm using JPA for the model and JSF for the controller and view.
Here's my Model.
@Entity
public class WebUser implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    private String lastName;
    private String firstName;
    private String middleName;
    private String username;
    private String password;
    public Long getId() {
        return id;
    public void setId(Long id) {
        this.id = id;
    @Override
    public int hashCode() {
        int hash = 0;
        hash += (id != null ? id.hashCode() : 0);
        return hash;
    @Override
    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields are not set
        if (!(object instanceof WebUser)) {
            return false;
        WebUser other = (WebUser) object;
        if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
            return false;
        return true;
    @Override
    public String toString() {
        return "web.model.WebUser[id=" + id + "]";
    public String getLastName() {
        return lastName;
    public void setLastName(String lastName) {
        this.lastName = lastName;
    public String getFirstName() {
        return firstName;
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    public String getMiddleName() {
        return middleName;
    public void setMiddleName(String middleName) {
        this.middleName = middleName;
    public String getUsername() {
        return username;
    public void setUsername(String username) {
        this.username = username;
    public String getPassword() {
        return password;
    public void setPassword(String password) {
        this.password = password;
}The controller and jsp are auto-generated from Netbeans. My question is, how will I convert the 'WebUser' object into a String so I can compare the value from input text to the value in the database?
Here is my validation method inside WebUserController.java
public void validateUsername(FacesContext facesContext, UIComponent component, Object value) throws ValidatorException {
        String newUsername = (String) value;
        System.out.println("new user name: " +newUsername);
        System.out.println("component: " +component);
        int webUserSize;
        StringBuffer sb = new StringBuffer();
        //webUsers.toString();
        if ((webUsers == null) || (webUsers != null)) {
            System.out.println("web users null");
            List<WebUser> allWebUsers = getWebUsers();
            webUserSize = allWebUsers.size();
            System.out.println("all web users: " +allWebUsers);
            System.out.println("size " +webUserSize);
            for(int i=1; i<=webUserSize; ++i) {
                sb.append(allWebUsers);
                System.out.println("username: " +sb.append(allWebUsers));
        }Honestly I'm new to java and having a hard time with this one. Hope someone can help me. Thanks a lot.
I know my code is a mess. :(

Thanks for the help guys! I used the "unique constraint" annotation of JPA and my problem is solved.
Here's the code:
@Entity
@Table(
    name="WebUser",
    uniqueConstraints={@UniqueConstraint(columnNames={"username"})}
public class WebUser implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    private String lastName;
    private String firstName;
    private String middleName;
    private String username;
    private String password;
    public Long getId() {
        return id;
    public void setId(Long id) {
        this.id = id;
    @Override
    public int hashCode() {
        int hash = 0;
        hash += (id != null ? id.hashCode() : 0);
        return hash;
    @Override
    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields are not set
        if (!(object instanceof WebUser)) {
            return false;
        WebUser other = (WebUser) object;
        if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
            return false;
        return true;
    @Override
    public String toString() {
        //return "web.model.WebUser[id=" + id + "]";
        return "web.model.User[username=" + username +"]";
    public String getLastName() {
        return lastName;
    public void setLastName(String lastName) {
        this.lastName = lastName;
    public String getFirstName() {
        return firstName;
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    public String getMiddleName() {
        return middleName;
    public void setMiddleName(String middleName) {
        this.middleName = middleName;
    public String getUsername() {
        return username;
    public void setUsername(String username) {
        this.username = username;
    public String getPassword() {
        return password;
    public void setPassword(String password) {
        this.password = password;
}Thanks again guys!

Need help converting quicktime movies into Flash files

I need to convert a QT, PhotoJPEG compressed, movie file into a .flv format. I have AE 6.5 Standard and it keeps quitting on exporting a SWV file which would could probably get me by with my client. But, again, it errors out saying something like a JPG is busy, or a file is busy.
I have FlipforMac,a purchased version. But I'm not sure if converting it into a .wmv and then a Flash file is the best route or is even possible.
Any suggestions or ideas of software that I could purchase??
~reicko

i don't think you have read up on the use of flash video
(FLV). there's nothing you need that you do
not already have (except maybe quicktime pro or some other
video editing program). the FLV exporter
comes FREE with flash 8. You should be able to open your
quicktime movie in QT PRO and export to FLV
format - then use any of the flash playback components for
FLV files - best bet is to read the help
docs on this subject and go to the devnet section of
adobe.com where there are several in-depth
articles about implementing flash video into your site.

Dummy Guide needed for converting AS2 code into AS3

I have to convert my existing AS2 code into AS3, but I might as well be reading chinese. I never even began to learn AS3, it was still fairly new at the time and the class ended before we had an opportunity to even touch on it. My major was not web design, it was the print side of design. I took an additional class, after I graduated, to learn web design and our teacher told us, basically, that we were designers, not coders so we won't be getting much into actionscripting, beyond the basics. At the time I was relieved, but looking back, I really wish we would have gotten more into it. Bottom line, I need to learn now.
Is there ANYONE that can help me out? I will list my code below, buy I am way beyond lost any help that can be provided, I would be so grateful!!!!
On the main timeline I have the basic..
stop(); -- I found the AS3 version, but I don't know what I'm looking at. I get "not_yet_set.stop()" and there are are 8 options I can choose from. I just want the timeline to stop until I tell it where to go next. And what is "not_yet_set"
Then I have my buttons, which are, basically...
on (release) {
gotoAndStop("Home");
Or "gotoAndPlay("Whatever");"
I also have buttons for scrolling...
on (press) {
play();
on (release) {
stop();
AND
on (press) {
_root.AboutMe_Controller.gotoAndPlay(…
on (release) {
_root.AboutMe_Controller.gotoAndStop(…
For the on(release) command, this is what I found as the AS3 version: not_set_yet.dispatchEvent()

because that's really as1 code, you have steeper learning curve than going from as2 to as3.
first, remove all code from objects, assign instance names to your buttons and you can then start on as3:
// so, if you name your home button, home_btn:
home_btn.addEventListener(MouseEvent.CLICK,homeF);
function homeF(e:MouseEvent):void{
gotoAndStop("Home");
p.s. the not_yet_set stuff is there because you tried to use script assist or some other actionscript shortcut.

Need to convert long data type to varchar2

I need to convert a long datatype in an existing table to a
varchar2, in either another table or view. I have a 3rd party
application which needs to query the data in the long data type,
but it can "handle" the long.
What is the best way to do this? I tried to make a trigger, but
I must be missing something. Here is the trigger.
CREATE OR REPLACE TRIGGER "PROD".SV_GET_RTG_COMNT
BEFORE INSERT OR UPDATE ON PROD.RELS_RTG_SEQ_COMNT
FOR EACH ROW
WHEN (OLD.rels_rtg_no = NEW.rels_rtg_no)
DECLARE
-- DECLARE VARIABLES
RTG_COMNT_VAR VARCHAR2(32);
RTG_COMNT_LONG LONG;
BEGIN
Select COMNT_TXT into RTG_COMNT_LONG
from rels_rtg_seq_comnt;
RTG_COMNT_VAR := 'TEXT' || substr(RTG_COMNT_LONG,1,32);
-- If INSERTING
Insert into SV_RTG_SEQ_COMNT (print_cd, comnt_no,
seq_no, rtg_no, comnt_txt) values
(:new.print_cd, :new.comnt_no, :new.seq_no, :new.rels_rtg_no,
rtg_comnt_var);
END;
I tried to use the substr command on the comnt_txt in view but
received an invalid datatype error.
Any help would be greatly appreciated.

Converting sql timestamp into a usable java format??

hi there.
does anyone know how to convert an sql timestamp into a usable java format? i have retrieved a timestamp from a mysql table in a jsp script and would like to convert it into the following format:
12:42pm | 08.07.02
as i understand it, i'll need to convert the timestamp into seconds since 1970 and then manipulate it as a calendar object? my first line is working, but i don't know what to do after...
java.sql.Timestamp sqlTimestamp = resultSet.getTimestamp("date_and_time");
next...?
any help would be much appreciated!!
thanks.

please excuse my java sytnax ignorance, but i've tried a bunch of different syntax arrangements and can't figure out how to use the getTime() method. what comes after my first line there?
java.sql.Timestamp sqlTimestamp = resultSet.getTimestamp("date_and_time");
then something like:
long msec=date.getTime(sqlTimestamp);
but that doesn't seem to work...
thanks for any help!
