Hi everyone, I am trying to connect Oracle database from my web application using Eclipse. But I got the error:org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; I used below code:

public static void initDB(){
try {
BasicDataSource ds = new BasicDataSource();
ds.setDriverClassName("oracle.jdbc.driver.OracleDriver");
ds.setUrl("jdbc:oracle:thin:@localhost:1521:xe");
ds.setUsername("mybank");
ds.setPassword("123456");

		jdbcTemplate  = new JdbcTemplate(ds); // throw exceptiong after this line
		isConnected = true;
		initSystemPros();
	} catch (Exception e) {
		System.err.println("Cannot connect to DataBase");
		isConnected = false;
	}
}

I tried to use SQL Developer to create a connection using above settings and successful. Do you know what is wrong ? Thanks and regards, Tai

Hi, I checked the log error file. For the select query, I got the below error: Error: 7886, Severity: 20, State: 1. 2014-07-14 11:27:01.50 spid52 A read operation on a large object failed while sending data to the client. A common cause for this is if the application is running in READ UNCOMMITTED isolation level. This connection will be terminated. For the delete statement, I got the message: Error: 824, Severity: 24, State: 2. 2014-07-14 13:34:10.12 spid51 SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x4da7af2c; actual: 0xda5e9af7). It occurred during a read of page (1:40403) in database ID 6 at offset 0x00000013ba6000 in file 'D:\CLCData\23_01_2013\CLC_LIS_Data.mdf'. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online But, I don't know how to fix it.

Hi everyone, I am creating a query to my database using SQL Server Management Studio There is a data error in my image field of my row. I still can select another fields, but when I select content of the image field I get below error: My query:

When I tried to delete this row. I got another error (Error 2): SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x4da7af2c; actual: 0xda5e9af7). It occurred during a read of page (1:40403) in database ID 6 at offset 0x00000013ba6000 in file 'D:\CLCData\23_01_2013\CLC_LIS_Data.mdf'.
