I'm trying to launch a server on my tomcat 7 on my eclipse indigo EE and I get the following error: "'starting Tomcat v7.0 server at localhost' has encountered a problem. The specified JRE installation does not exist" I checked the build path configuration and on the libraries section I have the JDK7 as JRE System Libraray and when I check "Installed JREs..." the correct path is there - "C:\Program Files\Java\jdk1.7.0_01". What else can be done? Many thanks. p.s. - I'm also using maven 3.0.3 Double click on the server to bring up the Overview. Click on Runtime Environment. Select the JRE from

Framework, and I got the following exception: RuntimeException occured : java.nio.file.FileSystemException: c:\work\foo\bar: A required privilege is not held by the client.

If anyone can answer here faster than I'll find the answer, me (and

How should I use AsynchronousServerSocketChannel for accepting connections?

由 三世轮回 提交于 2019-11-29 21:02:13
I would like to write an asynchronous server using Java 7 and NIO 2. But how should I use AsynchronousServerSocketChannel ? E.g. if I start with: final AsynchronousServerSocketChannel server = AsynchronousServerSocketChannel.open().bind( new InetSocketAddress(port)); Then when I do server.accept() , the program terminates because that call is asynchronous . And if I put that code in an infinite loop, an AcceptPendingException is thrown. Any suggestions on how to write a simple asynchronous server using AsynchronousServerSocketChannel ? Here is my full example (similar to the example in the

How do you configure aspectj maven plugin to use Java 7?

由 柔情痞子 提交于 2019-11-29 19:17:37
问题 What are the appropriate configuration/versions/plugin versions for the aspectj plugin to use Java 7? I am trying to upgrade from Java 6 to Java 7, and the aspectj compiler seems to not be compiling Java 7. I'm specifying the java source and target version as 1.7 in the plugin configuration for aspectj plugin and for the maven compiler plugin. I introduced Java7-specific syntax to my code, adding several language features such as string in switch and the diamond operator. During the build, I

Invoke private method with java.lang.invoke.MethodHandle

由 大憨熊 提交于 2019-11-29 19:09:32
问题 How can I invoke private method using method handles ? As far as I can see there are only two kinds of publicly accessible Lookup instances: MethodHandles.lookup() MethodHandles.publicLookup() and neither allows unrestricted private access. There is the non-public Lookup.IMPL_LOOKUP that does what I want. Is there some public way to obtain it (assuming that SecurityManager allows it) ? 回答1: Turns out it's possible with Lookup#unreflect(Method) and temporarily making method accessible

Java nio FileSystem Watcher locks directories. Deletion becomes impossible [duplicate]

由 梦想的初衷 提交于 2019-11-29 19:07:02
问题 This question already has an answer here: Java7 WatchService - Access Denied error trying to delete recursively watched nested directories (Windows only) 1 answer I'm using the new feature of Java7 for watching directories for changes (as it is described in the following tutorial: http://download.oracle.com/javase/tutorial/essential/io/notification.html ) The watching itself works (nearly) without problems. More or less I have two issues and I hope some of you have an idea how to handle it.
