"Invalid Server URL" 安装 GraphDB 时替换 .jar 文件后出错

Question

我试图安装 GraphDB 来补充默认的 Sesame。按照 http://owlim.ontotext.com/display/OWLIMv54/OWLIM-SE+Installation 中 'Easy Install' 的说明，我将 .war 文件从 GraphDB 分发复制到我的 Tomcat 目录并替换了预先存在的 .war 文件芝麻带来的。但是，在重新启动服务器后，我在 Sesame 下拉列表中没有看到 'OWLIM-SE' 个存储库。

在排除故障时，我将 C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\openrdf-sesame\WEB-INF\lib 中的 .jar 文件替换为最新的 Sesame 中的文件版本看看它是否有任何区别（我有 2.8.3）。

确实有所不同。我现在只得到 'Change Server' 页面。在将服务器的 URL 输入为 http://my.ip.address:8080/openrdf-sesame 后，我收到 "Invalid Server url" 错误。我已将服务器 url 从 localhost 更改为 ip 地址，以便我可以从外部访问它。我该如何解决两个问题：

让 Sesame 再次运行
安装 GraphDB

日志如下：

已解决！这是有效的方法：

I first installed GraphDB. Then, I replaced the jar files of GraphDB with those of Sesame 2.7.16. I copied the same set of files to the 'libs' folder of both Sesame-openrdf and Sesame-workbench. Though some jar files are duplicate, I did not remove one version for the other.
