需要帮助将目录中的所有 jar 文件包含到现有项目中
我已将一段共享点代码添加到现有的 java 文件中，该文件正在编译且工作正常。编写的共享点代码使用了一些外部库。现在我需要通过ANT将外部库添加到现有项目中。
我在 build.xml 文件中做了一些修改，因此解决了所有编译错误。但是，当代码执行时，我收到一条错误消息“java.lang.NoClassDefFoundError：net/entropysoft/eci/spi/IContentProviderFactory”。请帮我解决这个错误。
另请让我知道需要在 build.xml 文件中添加哪些内容来解决该错误。 所有 jar 文件都存在于目录“externallibs”中，
谢谢， 拉贾特
I have added a piece of sharepoint code to the existing java file which was compiling and working fine. The sharepoint code that is written uses some of the external libraries. Now I need to add the external library to the existing project through ANT.
I have done a few modifications in the build.xml file and hence resolved all the compilation errors. However when the code is getting executed, I get an Error message saying "java.lang.NoClassDefFoundError: net/entropysoft/eci/spi/IContentProviderFactory". Please help me resolving this error.
Also please let me know what needs to be added in the build.xml file to resolve the error.
All the jar files is present in the directory "externallibs"
Thanks,
Rajath

运行应用程序时，您需要在类路径中包含所有 jar 文件：
如果它是 Java EE Web 应用程序，则构建过程应将所有这些 jar 文件复制到生成的 Web 的
WEB-INF/lib文件夹中应用程序结构。You need to have all the jars in the classpath when running the application:
If it's a Java EE web application, the build process should copy all these jars to the
WEB-INF/libfolder of the generated web app structure.java.lang.NoClassDefFoundError: net/entropysoft/eci/spi/IContentProviderFactory并不意味着未找到net.entropysoft.eci.spi.IContentProviderFactory类。这意味着在类路径中的任何位置都找不到该类中使用的类。当类加载器尝试加载类但无法正确初始化类定义时，会引发此错误。要解决此问题，您需要查看类
net.entropysoft.eci.spi.IContentProviderFactory的源代码（通常在导入部分），并确定缺少什么 Java 类以及哪个类缺少的类所在的库。一旦您知道，您可以使用 JB Nizet 的答案将该库添加到您的类路径中。如果从 IDE 运行它，则需要将该库添加到 build.xml 中。java.lang.NoClassDefFoundError: net/entropysoft/eci/spi/IContentProviderFactorydoes not mean the classnet.entropysoft.eci.spi.IContentProviderFactoryis not found. It means the class that is used within this class are not found anywhere in the classpath. This error is thrown when the class loader is trying to load the class but it cannot properly initialize the class definition.To solve this problem, you will need to look at the source code of the class
net.entropysoft.eci.spi.IContentProviderFactory, usually at the import section, and determine what is the missing Java class and which library the missing class is in. Once you know you can add that library to your classpath using the answer by JB Nizet. If you run it from IDE, then you will need to add that library to you build.xml.
