J2EE Tester 测试器是一款用于测试发布于服务器端（如Weblogic, Websphere）的 EJB组件、Servlet以及 Beans的黑盒/白盒智能化测试工具。它的功能主要有以下三点： 1. 自动生成被测试类的覆盖度测试报告，生成相应的dmp文件。 2. 自动生成被测试类的出错报告，记录抛错的行数，出错类型,方法名称，时间以及该行的代码。 3. 按照需要在发生错误的行产生断点，让测试者查看此时各个变量的状态。 -J2EE Tester Tester is a test release for the server-side (such as Weblogic, Websphere) of EJB components, Servlet and Beans the black box/white box of intelligent test tools. Its main function has the following three points: 1. Automatically generated by test category test coverage reports, generate dmp file. 2. Automatically generated by the wrong type of test reports, record the number of rows behind mistake, error type, method name, time and the lines of code. 3. In accordance with the required line in the event of an error arising from a breakpoint, so that those who view the test at this time of the status variables.

连接池基本原理:连接池最基本的思想就是预先建立一些连接放置于内存对象中以备使用。对于多于链接池中链接数的并发请求，应在请求队列中排队等待。并且应用程序可以根据链接的使用率，动态增加或减少池中的链接数。达到链接的优化。 -The basic principles of connection pooling: connection pooling basic ideology is the pre-established links with objects placed in memory for use. For more than a few links to the pool of concurrent link request, the request should be in the queue waiting. And applications can be linked to utilization, dynamic increase or decrease in the number of links to the pool. To achieve the optimal link.
