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
[Code] ....
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.

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.

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.
calling a parameterized stored procedure in java jdbc from sql server.The stored procedure goes like this in sql

I have an java connection pool using glassfish and mysql jdbc connector. All is fine, my datasource is working using JNDI, etc. But i need to know some info about of connection pool status (maxPoolSize, current active, etc..). I need it to monitoring the connection in the web app.
All work fine. But i need get de pool size and MysqlDataSource class don't have a method to get it. In tomcat, i use org.apache.tomcat.jdbc.pool.DataSource with getMaxActive() and getActive(). And it work fine. How i can obtain it on glassfish server?
I'm new to Java. I need to run a SQL server stored procedure(that creates a unique job number) from Oracle SQL Developer (JDBC) in Java. The same Java code will be used in Applescript to run the SP. I found a code snippet online with the similar requirement. How to embed my SP in below code snippet? Below is the Stored Procedure and Code Snippet:
SP
EXEC Int.dbo.GetNewJobNumber '6852', 'Test Job', 'Manual SQL Query' 6852- CustomerCode, Test Job - Job Title, Manual SQL query - Shows how new job number was created.
I've got a very simple java program (J.java, see below) on my application server that successfully connects to an Oracle 11.2 database on a database server (both servers are Linux CentOS) using JDBC thin driver from Oracle.
As you can see from the setURL command in the Java code below, I've configured the application and database servers to sit next to each other, and they're on the same network (cross-cable connected to each other), so there's no network traffic on these (development) boxes except my code.
The problem is the execution time varies a lot. If I run it 5 times, it (seemingly randomly) could take 0.01 seconds, or 10 seconds, or 50 seconds, or over a minute to execute. If it takes over a minute (roughly), the program doesn't complete, but the error shown below is returned instead.
------error returned when execution take more than about 1 minute------- gf@host9 [~/dbwork]# java -cp ./ojdbc6_g.jar:.

I want to make a database and use it in my java program. I am thinking of using MS Access database, although I m not very sure, sine I will have to use this data later in the SQL database as part of C# program.
How to start to create and use MS database in java program.
I have seen in one tutorial that the steps are:
1. Install your database management system (DBMS) if needed
2.Install a JDBC driver from the vendor of your database
but I am not familiar with this. Any example, or is this above compulsory?
In MVC, M is the model, V is the view and C is the controller. But whatever projects I have made till now, I have a separate layer called data layer where I do all the database operations. In MVC, are we saying that the database operations are within the controller layer? That's quite a little mismatch! Separation of layers yet merge of controller & database operations!!
I would like to make a database using HTML and Java. I already made something like this using swing. I am just looking for some pointers here. I just started looking into Java Play 2 and I have a feeling this is what I am looking for. JavaEE is very complicated and I have read that it is being phased out. What is your opinion on this?
I want to make a static HTML page and put it on my home network and treat one of my computers as the sever accessing mySQL.
