Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
Keep the subject line brief, but descriptive. eg "File Serialization problem"
Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.
Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.
Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.

We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
When answering a question please:
Read the question carefully
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar
If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome

Good afternoon! I'm trying to create a custom generic Bean Validator for the email of an author and the name of a category to verify that they are unique and I wish I could use a custom JPQL, the name of the persistence unit in persistence.xml and other variables. However, I don't know how to pass variables inside isValid, I only know how to hardcode them.
Hi I am developing a library management system in net-beans. When I run it on my system it works fine however, iftry to run it on another system it gives me an error of javax.persistence.Persistence.createEntityManagerFactory("path_to_database_on_my_system"). But this path to database must be changed inthis function. How would I dothis? Need Help.
Been messing around for hours and eventually decided to seek the assistance of the internet.
I am trying to make a program where I/the user can add elements into an array (Name, age gender). Once elements have been added to the array, I want to then be able to search a String (name) to find the desired name I am after in the array. The context of the program is adding Climbers to a Climber Database (just an array) of who has climbed what mountain (haven't attempted adding the mountain stuff yet).
In what I've written so far, I keep getting the return null, saying that the searched String cannot be found. I have a feeling that I am failing to pass the parameters of the added element in the array.
For example, I add a 'climber' with the name John, 19, Male in the Climber Class. I then go to the ClubStats class to getClimber and search "John", the only one in the array and I receive a null..
FYI I am using BlueJ here so at a serious basic level.
* Write a description of class Climber here.
* @author (your name)
* @version (a version number or a date)
// Instance variables.// The climber name.privateString name;
// The climber age.privateint age;
// The climber gender.privateString gender;
* Constructor for objects of class Climber
*/public Climber(String newName, int newAge, String newGender)
// Initialise instance variables.
name = newName;
age = newAge;
gender = newGender;
