试图安装在泊坞机内,无论是vim还是nano,但我只能得到这个:

0% [Connecting to archive.ubuntu.com (91.189.88.152)]

退出码头并做ping archive.ubuntu.com,我得到回复,同时在docker内做它没有响应.

可能是什么问题呢？

如何计算存储过程以最快的方式返回的行数.存储过程返回大约100K到1M记录的行.

Google Maven依赖项可以解决此错误:

java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;J)V

码:

Blob blob = storage.get(blobId);
if(blob.exists()) {
    return true;
}

我如何重启整个JVM在我们的Windows Server,无需重新启动操作系统具有JRE,？

是否有类似的东西:

java -restart

或者这是不可能的.这个想法是,我加tool.jar在/lib/extJRE的文件夹,我需要重新启动JVM.

我刚刚发现这个项目提供了一种在自己的服务器集群上运行Google App Engine项目的方法.

http://code.google.com/p/appscale/

它看起来很有趣,有没有人有使用它的经验？

我正在尝试通过在浏览器URL /地址栏上执行此操作在我的Web应用程序上执行Javascript:

javascript:window.alert('test');void(0);

但是,没有任何反应,警报框没有出现？原因可能是应用程序在DevMode中运行？

是否有任何库允许通过添加注释来记录变量,例如:

@Log
String someValueToLog = someMethod(); 
@Log(level="debug",prefix="Here's the value=")
String someValueToLogAgain = someMethod(); 

该功能类似于在代码中添加此行:

log.info(someValueToLog);
log.debug("Here's the value="+someValueToLogAgain);

我@ExceptionHandler用来处理我的网络应用程序抛出的异常,在我的情况下,我的应用程序返回JSON响应,HTTP status以便对客户端进行错误响应.

但是,我试图弄清楚如何处理error 404以返回类似的JSON响应,就像处理的那样@ExceptionHandler

更新:

我的意思是,当访问不存在的URL时

我一直试图运行这个Arquillian的例子

https://github.com/arquillian/arquillian-examples/tree/master/arquillian-tutorial

在Eclipse中导入时没有错误

基于此JIRA问题:

https://issues.jboss.org/browse/ERRAI-68

GAE对Errai的支持是不可行的.

它是不是真的可行或有办法解决方法:

• Errai UI肯定会起作用,因为这是针对GWT的
• 然而,Errai巴士,有一个解决方法,使其工作.包装好的东西？
