and this is my JSP.The problem is easy, when I click on the grid for deleting the record two things happen, or the record is deleted only on JSP but not in my Database or Nothing happens even on my JSP, it is because I don't know how to get values from my jsp and send them to replace the ? in my delete query I tried even to give a name to the <tr> which contains Name and Last name but obviously i guess it works only for input type ex. Textbox.
I currently have all the code working to fill my database and to display it, although I would like to have it displaying in a JPanel but I cannot figure it out so a JFrame will do. Add, Edit and Delete button for the JTable so I can add rows to the table and database, edit existing rows and delete rows also.
@Transactional public long getSequenceSedeB(Long id) { BigDecimal seqValue = nu String sql = "SELECT MAX(ID) FROM SEDE_B_ALLEGATI_A WHERE ID_SEDE=:id"; SQLQuery query = getSession().createSQLQuery(sql);

But it do not works; this is the log.
type.NullableType (NullableType.java:182) - could not read column value from result set: ID; Invalid column name
I created a database in mysql, but I have problems communicating with the DB in java.
Here is the error :
java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/books at java.sql.DriverManager.getConnection(DriverManager.java:604) at java.sql.DriverManager.getConnection(DriverManager.java:221) at displayauthors.DisplayAuthors.main(DisplayAuthors.java:30) java.lang.NullPointerException

HERE IS THE CODE
public class DisplayAuthors { // database URL static final String DATABASE_URL = "jdbc:mysql://localhost:3306/books"; // launch the application public static void main( String args[] )
This question is not about syntax but a best way to handle something. What is the best way to store a image into a database? For example converting it into binary etc. I just wanted to get some opinions.
This the output of java from my PC under linux platform (rhel 6.5).

I have completed an assignment for my university in which I had to make a Java NetBeans project. My project is now completed but now I have to make a setup of my NetBeans project and give the university the setup file, only.
My question is, the software I made has a database attached to it, meaning the purpose of the software is to be used with the database. Values must be saved in the database, deleted from the database etc.. I have used MySQL database connections with the JDBC driver
I have used exe4j to make the .exe file and Setup Factory to make the exe file and setup file respectively. Once I make the setup and run the setup, the application works, ON MY COMPUTER. The computer which made the software. But once I take it to a computer in which MySQL was not installed, the setup installed, but the software did not work.
I have small Java code, which execute every day and checks for data in database using Cronj Schedular and everything works fine, but recently I have observed that, it is failing due to
java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@160.110.xx.xxx:1521/test
At the same time, when I run my test code to check Database connectivity that works fine without above exception. I'm unable to figure it out. Although, there was just slight code change, but that was nowhere related to Database or Database connection.
dbconf.java public class dbconf { private Connection connect; private String connstr; public Connection getConnection() throws SQLException { connstr = "jdbc:oracle:thin:@160.110.xx.xxx:1521/test";

So, you can see, It failed on 3rd of July and 5th July as well. But, in between it ran fine.
I have a template file which I'm tring to upload into a database using setBlob or setBinaryStream but I'm getting the following error:
java.lang.AbstractMethodError: setBlob at weblogic.jdbc.wrapper.PreparedStatement.setBlob(PreparedStatement.java:1005) at com.capitalone.citrix.ssp.dao.KatetDaoImpl.uploadReport(KatetDaoImpl.java:1697) at com.capitalone.citrix.ssp.services.FileOpsImpl.generateDownload(FileOpsImpl.java:648) at com.capitalone.citrix.ssp.controller.JSONController.display(JSONController.java:61) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
[Code] .....
I'm using :
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production Weblogic Server Versions: 10.3.0.0 with Java 1.6.0_05
The driver class name for the weblogic datasource: weblogic.jdbcx.oracle.OracleDataSource
Initially, I tried:
sqlQuery = new StringBuffer(); ps = null; sqlQuery.append("insert into KATET_REPORTS (FILE_DATA)");
[Code] ....
This failed, so I changed ps.setBlob(1,is) to ps.setBinaryStream(1,is). This failed as well with teh same error, just for setBinaryStream instead of setBlob.
Is there a known inconsistency between that driver and this Weblogic version? Is there something else going on? If I haven't given enough data to debug the issue here, what other data should I gather?
I am trying to run a simple program that connects to a mysql database and prints out some fields. I am using Eclipse.
THe problem I am having is on the following line of code.
Class.forName("com.mysql.jdbc.Driver");
I get an error:

I have done some research and from what I have found is that I need to alter the class path to pick up the driver. When I downloaded the .msi I ran it and then the program closed. Where the files are ??? How to locate and import the file so I need to get my program to run?
I have included all the of the source code below.
package mySQLConnect; import java.sql.*; public class Connect { // JDBC Driver name and database URL static final String JDBC_DRIVER = "com.mysql.jdbc.Driver"; static final String BD_URL = "jdbc:mysql://localhost/sstbde";
We currently have an application which uses JDBC to connect to the backend database (DB version - 11.2.0.3 ). The application uses a properties file in which the password for the db schema is hardcoded in plain text format. Due to security restrictions we have been asked to make sure the password is encrypted in the file and no direct access is made to the schema using the plain text password. Best options we can use to make this password encrypted both at Oracle DB side and Java side.
I finally made the app to draw 10x10 map out of 50x50 pixel blocks.Now I can't imagine how to make a camera and lock it on character. I know how to make a character, but I just want to understand how locking the camera on character would look.
package tiled; import org.newdawn.slick.*; import org.newdawn.slick.state.*; public class play extends BasicGameState { int xSize = 10; int ySize = 10;
I want to implement new locking mechanism similar to like how threads locking or synchronized does the operation. Any inputs to implement out own locking mechanism ?
calling a parameterized stored procedure in java jdbc from sql server.The stored procedure goes like this in sql
create proc patientreg @id int as begin select [patient_id],[Psurname], [pFirstname], [pMiddlename], [reg_date], [DOB], [Sex], [Phone_num], [Addr],[Email],[dbo].[fncomputeage](DOB) from [dbo].[Patient_registration] where [patient_id] = @id end please note dbo.fncompute(DOB) is a function
I know that below code would put a lock on current instance of DemoClass, What I am not sure of is the role of lock on Object Class in second example. How does below works - Is it putting a lock on Object Class? If yes how will putting a lock on Object? I mean, locking DemoClass ensure no two threads access it concurrently, how does this apply to Object class?
private final Object lock = new Object(); synchronized (lock) public class DemoClass { public void demoMethod(){ synchronized (this)
I am trying to execute a program from the command prompt. I type java -jar zuul.jar (zuul is the name of my project) and I get a message that java is not recognized as an internal or external command. What do I do wrong?
I've this "program" that shall manage to register a dog, show a list of all registerd dogs and delete dogs from the list.. And I'm stuck at the latter one. So I've to classes, one for the dog and one for register/program. This is my main program
package hundRegister; import java.util.Scanner; import java.util.ArrayList; public class HundProgram { private static Scanner tangentbord = new Scanner (System.in); private static ArrayList<Hund> hundlista = new ArrayList<>();
[Code] ......
So, when I enter a name on a dog that exist on my list, it just jumps down to } else { and write that dog can't be found even if I write the exact name on the dog.
I can't see what I'm doing wrong, been trying out different methods now.
