Question

Hello Good Afternoon Guys，

我对Xstream jar有疑问。我正在编写独立的后台进程，它将XML转换为对象。它使用jdk1.6.0_35在我的eclipse中工作我创建了jar文件并使用jdk1.6.27部署在服务器中它无法正常工作。

错误是

java.lang.NoClassDefFoundError: Could not initialize class net.sf.cglib.proxy.Enhancer

可能是什么问题？提前致谢。

我已将JDK复制到服务器并尝试了相同的结果。

XStream xstream1 = new XStream(new StaxDriver()); 

//I tried both Stax and DOM Drivers same result 

XStream xstream1 = new XStream(new DomDriver()); //Same result. 

xstream1.alias("custom01", ConversionXstreamHelper.class);
//binding between xml elements and class and variables, 
................ 
ConversionXstreamHelper helper = (ConversionXstreamHelper)xstream1.fromXML(line);

我能够解决这个问题。 Xstream有CGLIB的问题，我已经将CGLIB-NODEP jar文件添加到我的maven构建并构建了Jar，它正在工作

我正在使用XStream 1.3 jar和cglib-nodep2.1_3.jar文件。

谢谢，
