Java EE 中 Struts 1.2.9 的分页
我尝试在 Objectweb Lomboz Eclipse 版本 3.3 中的 Struts 中进行分页。但我收到“未找到类”错误。
错误是

我不知道代码有什么问题。我从 Viralpatel.net 复制的。我有一种感觉,这段代码仅适用于 struts 2。因此,如果您有任何适用于 struts 1.2.9 的分页程序,请在答案中提供。
I tried pagination in Struts in Objectweb Lomboz eclipse version 3.3. But I got a "no class found" error.
The errors are

I don't know what is wrong with the code. I copied it from viralpatel.net. I've got a feeling that this code is only applicable for struts 2. So, if you have any pagination program for struts 1.2.9, please provide this in an answer.

请检查错误的根本原因。它明确指出:
这意味着未找到类
UnhandledException
(来自org.apache.commons.lang
包)(在类路径中的任何位置)。从 Apache Commons 下载最新的 Apache Commons 库,并将 jar 放入项目的
WEB-INF/lib 中
目录或在类路径中声明路径。Please, check the root cause of the error. It clearly states:
Which means that the class
UnhandledException
(fromorg.apache.commons.lang
package) is not found (anywhere in your classpath).Download the latest Apache Commons library from Apache Commons and put the jar inside your project's
WEB-INF/lib
directory or declare the path in the classpath.
