当在程序中使用jasperreport加载模板时报class: groovy/runtime/metaclass/java/util/HashMapMetaCl

ps. I don't know what issue type I have to tag, please forgive if this is not a bug.

找了好久没找到答案，老外网站有不能完全看明白，哎只能自己结合网上的提示摸索，最后中终于找到了，是因为json包的版本低了，原来是struts-lib-2.1-jdk15,后来换成struts-lib-2.2.2-jdk15,见附件中

好吧。我试了下，解决办法是：把你的文件的语言改成java。
点击你的那个文件，在属性那，有个language，改成java就行。
