实际上

I  want to write data in property file that data comes from jsp file(user entered data). but above code is not working.

我需要 - -1。在属性文件中写入用户输入数据而不影响属性文件的先前数据。

但它提出了一些问题 -

1 - 。 EXCEPTION：javax.servlet.ServletException：实例化servlet类com.igate.controller.TestController时出错 2。 java.lang.NoClassDefFoundError：org / apache / commons / configuration / ConfigurationException 3。 java.lang.ClassNotFoundException：org.apache.commons.configuration.ConfigurationException

这是完整的堆栈跟踪。

这是完整的堆栈跟踪.. HTTP状态500 -
