Java spring XSD

A problem occurs when spring2 application is not connected to the Internet recently:

After debugging, I found that I had to go down the XSD from the Internet, so I modified the problem. First download the XSD and other files used, and then specify the files in the local directory, such:

<Beans xmlns = "http://www.springframework.org/schema/beans" xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance"
Xmlns: AOP = "The http://www.springframework.org/schema/aop" xmlns: Tx = "The http://www.springframework.org/schema/tx"
Xsi: schemalocation = "http://www.springframework.org/schema/beans _ XSD/spring-beans-2.0.xsd
Http://www.springframework.org/schema/aop _ XSD/spring-aop-2.0.xsd
Http://www.springframework.org/schema/tx _ XSD/spring-tx-2.0.xsd"
Default-Lazy-init = "true">
......

In struts. XML, if it is set to type = "Redirect-action", the value in form will be lost, including the value of the button.

Another problem is that if JDBC of mssqlserver2005 is used, it cannot be executed in. jar after packaging. The following error occurs:

Unpack the package and execute it again.
