I'm new in JSF, so maybe this is a very simple problem: My small application actually uses 'primefaces ' and I'd like to display the course of some laboratory values this way:
I have a need to refresh my database for every 15 seconds. I have to work with jsp ajax and jquery. For small amount of db entries it is ok but My application is going to handle huge records more than 20000. In my present scenario, Im forwarding request to another jsp page which communicate db and returns a table as result. Instead of this what are things I need to do?? This is just a sample application only. On success I am gonna implement using Spring, hibernate. So instead of table returning json or arraylist like that will work??
question: A stored procedure to insert records into deliveries table HINT create stored procedure with parameters for each field in the deliveries table for ex customer address, phone, email and receivers’s address etc this is my answer, this store procedure right or wrong. if wrong, can you share with me
create or replace PROCEDURE ADD_ORIENT ( EXCUSTOMER_NAME IN VARCHAR2 , EXCUSTOMER_PHONE IN VARCHAR2 , EXCUSTOMER_EMAIL IN VARCHAR2 , EXCUSTOMERRECEIVERADDRESS IN VARCHAR2 ) AS BEGIN NULL; END ADD_ORIENT;
Introduction: There is a glossary table of English and French words. The glossary table has duplicate rows and is out of order. I would like to remove the duplicates and sort them by the English column.
1. Open the glossary.html file in your browser, you will see a table on the left with an English column and a French column. On the right hand side of the screen you will see the unit test results. As you complete each TODO the unit tests will pass.
2. There are five areas marked TODO in the glossary.html file,
complete all of the TODOs. Check that all of the unit tests pass. This test project uses the following frameworks:
I am making rows and columns in the form of a multiplication table, listed below is my code:
package assignments; public class MultTable { public static void main (String [] args) { int row, column, x, y; for(row = 0; row < 8; row++)
[Code] .....
If you see my sample run you can see that I have the multiplication table down but, I haven't completed it. I have to make the bottom left half of the whole table blank somehow. For example, I have to make it halfway through the middle of the table the bottom left half full of white space...
5 6 7 8 9 12 14 16 18 21 24 27 32 36 90
hm, it's supposed to be the other way around horizontally.
I have a database table containing two columns A and B. They both contain integers. I'd like to know if it's possible, when displaying them in a JTable, to be combined in one column X. I still need, however, to be able to distinguish them from each other when selecting a row from the JTable. E.g. to store each of the values in a a separate variable. Maybe I can combine them when reading from the ResultSet and use some sort of delimiter ? But how?
I've written two programs. My first program compares the difference of two text files and prints the differences in an output. My second program creates a simple Html table. I would like to write my output to this table. How would I go about doing this in java?
I have an application that displays a GUI and this GUI displays a table with several columns and rows. I have a class that extends DefaultTableModel. I wrote the code that displays the GUI. When the database table changes, how would I updated the GUI dynamically? Do you have any sample code that does that?
I am trying to put together a small application in my spare time. Nothing major, but one thing I want it to do is accept a few inputs, and take those and add them to a table with columns for use later (printing, calculations, etc). I was originally looking at something like Jtable, but that looks just like an excel spreadsheet done Java, so not what I'm looking for.
I'm looking for something that's read-only, where I can insert data from input fields, and then perform calculations with the column data later.
I had to make a table showing different values for converting kg to lbs and I'm confused because when it compiles, some of the decimals show correctly and some of them show with several 0's added on with another number on the end. I've tried to do math.random, but I'm not sure how to tie it in with my program.
//1 kg = 2.2 lbs public class kg_to_lbs { public static void main(String[] args) { //not sure if values are needed.. int kg = 1; double lbs = 2.20; //Table title
Budget program. Here is my situation, I have 2 tabs in a GUI, one tab adds a transactions when the add button is clicked, and in the other tab displays a table showing all the transactions. In my code, I want it so that when the user chooses a deposit(combo box variable name = cbType, indexnumber for deposit is 0) it will add to the total and when the user chooses withdraw(index number is 1) then it will subtract it from the total. Here is the code.... (note as well, the code also adds a new row to the table)
So when I tested the program with 2 transactions, the first transaction was a deposit and the 2nd transaction was a withdraw. The end product was that both amounts were subtracted from the total. When I did a withdraw first and a deposit second, the amounts were both added together.
This is my codes in a button that if I click it . that information will send to Jtable but the problem is the jtable is in another frame so how can i connect this ?
DefaultTableModel model = (DefaultTableModel) new admin().tableBagtags.getModel(); if (txtName.getText().equals("")) { JOptionPane.showMessageDialog(null, "Please fill out all fields.", "Error!", JOptionPane.ERROR_MESSAGE);
How to sort data from a .csv file. The file has a column that contains duplicate groups, and a column that has duplicate employee id's. I need to take the data and sort it into rows. The employee's id will be in the first column, then the groups the employees belong in will occupy the following columns. The groups and employees are dynamic.
groups| empId ----------------- Group A| a1234 | Group A| e3456 | Group A| w3452 | Group A| d3456 | Group A| j7689 | [Code] ....
I want to format the .csv as follows:
-------------------------- empId | group 1 | group 2 | -------------------------- a1234 | group A | group B | --------------------------- w3452 | group A | group B | ---------------------------
Is there a way to inform the Entity Manager or force the JPA provider to reload data from the database? The scenario could be data being updated by a store procedure or direct SQLPlus maintenance, without restarting the Application Server, the JPA need to load the newly updated data from the database.
I think the current JPA API is not enough. The void refresh(java.lang.Object entity) from EntityManager need to pass in the Entity object, I will like to know how to refresh the entire JPA Entity data after the physical table data being update from backend.
I have a program which consist of several classes. The program reads a pom file and parses the data and then writes the data to a static table. The issue I'm having is with writing my LIB file data to my table. In the HtmlDataTable Class Im trying to write the files that are read in the lib directory to the table. My table currently consist of 3 columns (missing jar files,Lib Directory files, and POM file data) currently Im only able to write the missing jar files data to my table. In the HtmlDataTable class there is a for statement where I write the missing jar file data to my table. Im also trying to write the contents of the Lib directory within this statement as well. This is where I'm having my issue. My other classes consist of a SAX parser which parses the xml file, a class that creates my static table and a class that compares the jar files in my lib directory to the jar files in my pom file. . Theres a lot of code so I included the parts I felt were useful. If needed I can include the other classes as well.
public class ReadPomFile extends DefaultHandler { public static void main(String[] args) { try { // obtain a SAX based parser to parse XML document
I am very new to Java Swing. I have to create a TreeTable in Java Swing with a Parent Row having say 6 columns and its all child row having just 4 columns. like shown below
I'm trying to show mysql data in JSF using this example [URL] .... . I figured out what <h:dataTable value="#{userBean.getUserList()}" var="u" border="1"> must be <h:dataTable value="#{userBean.userList}" var="u" border="1"> but getting error:

public void createSearchArea(){ filterText = new JTextField("Search Here"); filterText.setForeground(Color.gray); filterText.setBounds(130,5,950,25); filterText.getDocument().addDocumentListener( new DocumentListener() {
[Code] .....
I want to add a text to JTextField whenever the text field is clicked it should be removed and if user types nothing then it should come back.
I've used focus listener but on focus lost my JTable also stops showing data in it.
The assignment is to create a program that accepts entries from a user for 3 variables then saves the data to a file. There are other programs that use the file created. One program displays the non-default records. The next program allows the user to enter the id for the employee and displays the first and last name for that id number. The last program allows the user to enter a first name. It then displays all id numbers and last names for records with that first name.
Given the above situation, I am stuck on creating the first program. I can make the text file and write the information to it. However, when the file is created, a space is placed in between each entry for some reason. I cannot figure out how to get rid of this space so that I can display the appropriate records for the remaining programs. Below is the code and a view of my problem.
import java.nio.ByteBuffer; import java.nio.channels.FileChannel; import java.nio.file.*; import java.io.*; import static java.nio.file.StandardOpenOption.*; import java.util.*; public class WriteEmployeeList {
[Code] .....
The values for nameFormat and lnameFormat are 10 spaces. This is how the book told me to make sure everything is uniform and searchable. The file contents look like this when viewed in notepad.
I am using netbeans swing to do my little project . I have one table which is populated by data from a database. I also have another table which should be populated when a user selects a certain row in the first table.Both table have only one column. The logic is when a user selects on row 1,the data in that row should be obtained and should be used to search for certain entities in the database which are returned and used to populate table 2.So after a user selects row1 and decides to select row2 the second table should be updated accordingly. I have attached the java file
