我在启动tomcat zip文件时遇到了问题。我对jsp和servlet完全陌生。我已经安装了tomcat7.0.52并设置了path和java_home。在我的一个系统中,它工作得很好,但在另一个具有相同配置的系统中,它制造了麻烦,我不知道为什么。我之前已经安装了tomcat的安装程序,但现在我必须卸载它并下载tomcat的压缩文件。所以现在我面临以下异常,我猜问题是tomcat不能部署它现有的项目。我已经在网上搜索过了,但我还是找不到。

我正在使用带有MockSchemaRegistryClient的为我们的kafka系统构建一个集成测试。我正在为我们的一个Stream拓扑构建一个测试,该拓扑是使用Streams API (KStreamBuilder)构建的。此特定拓扑将KStream (stream1)送入KTable (table1)。
我在将来自表1的KTableProcessor的输入馈送到stream1时遇到错误:

我想知道我是否可以在下面的问题上得到一些帮助。

如果我没有将MySql数据库连接到Sonar,那么web UI在localhost:9000上加载就不会出现问题。如果我更新MySQL的配置文件,web将不会启动,但我从日志中看不到任何提示。

我用Java语言创建了一个脚本库,而不是Java代理。

我对JDBC的理解是,它根据JVM的默认区域设置Oracle NLS_LANGUAGE/NLS_ based会话参数。对于一个独立的swing应用程序来说,这很方便,但是对于一个java webapp来说,这似乎是无用的。我能想出的唯一解决方案是在实际执行数据库查询之前专门设置会话参数,类似于:

Statement s = c.createStatement();
s.execute("alter session set NLS_LANGUAGE = 'SPANISH'");
// Do
