java - Derby 错误 : Could not find or load main class org. apache.derby.drda.NetworkServerControl

Question

我刚刚在 Windows 10.12.1.1 上安装了 Apache Derby 的最新官方版本(2015 年 10 月 11 日/SVN 1704137)

并尝试将其安装在Derby网络服务器中，本地主机一切正常，但是当我执行此命令(java org.apache.derby.drda.NetworkServerControl start -h myhost -p 1368)以使其接受IP其他时比本地主机我得到这个错误(正如你在下面看到的，在这个命令之前一切都很好)

C:\>set DERBY_INSTALL=C:\Apache\db-derby-10.12.1.1-bin


C:\>set CLASSPATH=%DERBY_INSTALL%\lib\derbyclient.jar;%DERBY_INSTALL%\lib\derbytools.jar;.


C:\>cd %derby_install%\bin

org.apache.derby.drda.NetworkServerControl


C:\Apache\db-derby-10.12.1.1-bin\bin>cd..


C:\Apache\db-derby-10.12.1.1-bin>cd lib


C:\Apache\db-derby-10.12.1.1-bin\lib>java org.apache.derby.drda.NetworkServerControl start -p 1368

错误:无法找到或加载主类 org.apache.derby.drda.NetworkServerControl

我仔细检查并确保在 lib 文件夹中找到 jar 文件 derbynet.jar 并且还包含 NetworkServerControl 类

Answer 1

我找到了答案，我只是想发布它以防有人遇到同样的问题，所以而不是使用

 C:\Apache\db-derby-10.12.1.1-bin\lib>java org.apache.derby.drda.NetworkServerControl start -h hostname -p 1368

只要这样使用它，它对我有用

C:\Apache\db-derby-10.12.1.1-bin\lib>java -jar derbynet.jar start -p hostname -p 1368
