Both the UML Tools, Green UMLand euml2, that you mentioned, don't show support for Eclipse Juno as of now. May be thats why they're not working. They show versions compatibility up until Eclipse 3.7 (Indigo)
到目前为止，您提到的 UML 工具Green UML和euml2都没有显示对 Eclipse Juno 的支持。可能这就是他们不工作的原因。他们显示版本兼容性直到 Eclipse 3.7 (Indigo)
