无法从w3c加载java类 [英] Unable to load java class from w3c

问题描述

我正在尝试使用ELKI进行OPTICS聚类（ http：//elki.dbs.ifi。 lmu.de/ ）。

I am trying to do OPTICS-clustering with ELKI (http://elki.dbs.ifi.lmu.de/).

我尝试用提供的gui运行聚类，但后来我得到了这个例外：

I try do run the clustering with the provided gui, but then I get this exception:

Error in starting visualizer window.
java.lang.NoClassDefFoundError: org/w3c/dom/svg/SVGSVGElement

我是unzi将w3c.jar导入 / usr / share / java 并进入程序的路径。但它仍然给我同样的错误。

I unzipped w3c.jar into /usr/share/java and into the path of the program. But it still gives me the same error.

我有一个很旧的Ubuntu（10.04），OpenJDK版本IcedTea6 1.13.3。但我猜这不是造成麻烦的，对吗？

I have quite an old Ubuntu (10.04) with OpenJDK version IcedTea6 1.13.3. But I guess that is not was is causing the trouble, right?

怎么办？

推荐答案

我认为你仍然需要将这个jar添加到classPath然后它会被识别。我不确定你在netbeans中使用什么ide，例如右键单击项目>库>添加jar / library。然后你的classLoader应该抱怨。

I think you still have to add that jar into classPath and then it will be recognized.Im not sure what ide you use bud in netbeans for instance rightclick project>libraries>add jar/library.Then your classLoader shoudnt be complaining.
