Java-RDF-Gravity 1.0-无法启动应用程序

我试图在Windows 7 x64位计算机上安装RDF-Gravity 1.0.安装失败,并显示消息无法启动应用程序.下面提供了“详细信息/例外”中的例外.如果有人知道如何克服它,我将感激您.

编辑：我遵循了约书亚的有用评论,它们看起来很有希望.由于我对JNLP的了解不多,因此我无法弄清楚“如何使Java Web Start应用程序使用禁用的缓存？”.另外,在浏览了rdf visualization tools的博客后,我发现了与RDF-Gravity类似的东西,称为welkin,它也可以可视化RDF.

解决方法:

RDF Gravity的Webstart版本不再在某些系统上运行的原因是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,this thread解释了为什么会这样.

受此影响的人可以下载可用的RDF Gravity版本here.zip存档中包含的“ rdf-gravity.jar”是可运行的jar.

最好
