64 bits mysql 5 doesn't work on 64 bit windows vista(or 7)

When install the mysql, it came out below 
 1. Prepare configuration (pass)
 2. Write configuratin file (pass)
 3. Start service (pass)
 4. Apply security setting failed with follwoing error

  Error Nr.  1045
  Access denied for user root@localhost (using password:NO)


Here are the steps that worked for me:

NOTE: I did not have to open TCP port 3306 at firewall.

1. When service startup fails at MySQL Instance Config Wizard, cancel the wizard, go to
Services windows and make sure the MySQL Server is stopped.

2. Execute again MySQL Instance Config Wizard (The service should start now)

3. If step 4 fails (Apply Security Settings), cancel the wizard

4. Create a TXT file (i.e. C:\mysqlpassword.txt) with the following lines

UPDATE mysql.user SET Password=PASSWORD('mypassword') WHERE User='root';

5. Open a Command prompt (former DOS console) and execute:
(run as administrator ** very important)
mysqld --defaults-file="C:\ProgramData\MySQL\MySQL Server 5.5\my.ini" --init-file="C:\Users\sxu\Documents\mysqlpassword.txt" --standalone --console

6. Open a different console and execute: "C:\Program Files\MySQL\MySQL Server
5.1\bin\mysqladmin" -u root -p shutdown (enter the password specified in file
mysqlpassword.txt, of course)

3. Execute again MySQL Instance Config Wizard (The security setting should be applied)
In addition, I also met the fetching issue when I tried to use the db in 5.09.
Run : mysql_upgrade -u root -p , and fix this issue.

Stretch a row if data overflows in jasper reports

It is very common that some columns of the report need to stretch to show all the content in that column. But  if you just specify the property " stretch with overflow' to that column(we called text field in jasper report world) , it will just stretch that column and won't change other columns, so the row could be ridiculous. Haven't find the solution from internet yet. So I just review the properties in iReport one by one and find two useful properties(the bold highlighted in example below) which resolve the problems.   example:
<band height="20" splitType="Stretch"> <textField isStretchWithOverflow="true" pattern="" isBlankWhenNull="true"> <reportElement stretchType="RelativeToTallestObject" mode="Opaque" x="192" y="0" width="183" height="20"/> <box leftPadding="2"> <pen lineWidth="0.25"/> …

Spring - Operations with jdbcTemplate

This class manages all the database communication and exception handling using a java.sql.Connection that is obtained from the provided DataSource. JdbcTemplate is a stateless and threadsafe class and you can safely instantiate a single instance to be used for each DAO.

Use of Callback Methods
JdbcTemplate is based on a template style of programming common to many other parts of Spring. Some method calls are handled entirely by the JdbcTemplate, while others require the calling class to provide callback methods that contain the implementation for parts of the JDBC workflow. This is another form of Inversion of Control. Your application code hands over the responsibility of managing the database access to the template class. The template class in turn calls back to your application code when it needs some detail processing filled in. These callback methods are allowed to throw a java.sql.SQLException, since the framework will be able to catch this exception and use its built-in excepti…
