java.lang.NoClassDefFoundError: org/apache/jsp/admin/Login_jsp (wrong name: org/apache/jsp/Admin/Login_jsp)
时间: 2023-10-26 13:45:34 浏览: 46
This error occurs when the file path and name of the JSP file do not match the path and name specified in the web.xml file. In this case, the JSP file is named "Login_jsp" with a lowercase "l" in the "admin" folder, but the error message shows "Login_jsp" with an uppercase "L" in the "Admin" folder.
To resolve this error, check the web.xml file and make sure the path and name of the JSP file are spelled correctly and match the actual file path and name. Additionally, check the case of the folder and file names to ensure they match exactly.

java.lang.NoClassDefFoundError: org/apache/xml/serializer/TreeWalker
java.lang.NoClassDefFoundError: org/apache/xml/serializer/TreeWalkerJava中的一个错误,它表示在运行时找不到指定的类。具体来说,这个错误表示在程序运行时,JVM无法找到org.apache.xml.serializer.TreeWalker类。
这个错误通常发生在以下情况下:
1. 缺少相关的依赖库:如果程序依赖于某个库或JAR文件,并且该文件不存在或无法访问,就会导致NoClassDefFoundError错误。
2. 类路径问题:如果类路径配置不正确,JVM将无法找到所需的类文件。
3. 版本不匹配:如果程序依赖的类库版本与当前环境不匹配,也可能导致NoClassDefFoundError错误。
解决这个错误的方法包括:
1. 检查依赖库:确保所需的依赖库存在,并且可以被程序正确访问。
2. 检查类路径配置:确保类路径配置正确,包括检查环境变量和项目构建工具(如Maven或Gradle)的配置。
3. 检查版本匹配:确保程序依赖的类库版本与当前环境兼容。
