我试图在 Windows 7 x64bit 机器上安装 RDF-Gravity 1.0。安装失败并显示一条消息Unable to launch the application。下面提供了例外情况Details/Exception。如果有人知道如何克服它，我将感谢你。

编辑：我遵循了 Joshua 的有用评论，他们看起来很有希望。由于我对 JNLP 了解不多，所以我无法弄清楚“如何使 Java Web Start 应用程序在禁用缓存的情况下工作？”。或者，在浏览了rdf 可视化工具的博客后，我发现了类似于 RDF-Gravity 的东西，称为welkin，它也可以可视化 RDF。

RDF Gravity 的 Webstart 版本在某些系统上不再工作的原因是 colt.jar 的证书不再被某些 JVM 版本接受。对于那些对细节感兴趣的人，这个线程解释了为什么会这样。

受此影响的人可以在此处下载 RDF Gravity 版本。zip 存档中包含的“rdf-gravity.jar”是一个可运行的 jar。

最佳
