Java Web项目无法从Eclipse内部执行DLL文件

我有一个web项目，当我将该项目部署到单个tomcat时，该项目运行良好，但当我试图从Eclipse内部运行同一个项目，并且在同一个tomcat实例中，该项目不工作时，会引发以下异常：

 java.lang.UnsatisfiedLinkError: C:\ms4w\Apache\cgi-bin\mapscript.dll:

有人能帮我解决上述异常吗？

您是否仔细检查了文件是否确实存在于

C:\ms4w\Apache\cgi bin\mapscript.dll

？@maba是的，它在那里，这就是为什么从单个tomcat实例来看，我指的是eclipse外部的工作，但从内部的eclipse不工作：（我想不出答案issue@j.singh您能在两种环境中发布

System.getProperty（“java.library.path”）；

的结果吗？谢谢大家，通过在环境变量中添加包含DLL的文件夹，问题得以解决

String  library = System.getProperty("mapserver.library.name", "mapscript");
System.loadLibrary(library);
