java-7

问题 I had been using 2010 Macbook Pro for a while and had updated the Mac OSX to the latest version, and I had been suffering the slow speed for a long time. So last night I googled and do some cleanup , such as fix disk permissions, but the Mac was still slow. And someone suggest to re-install MacOSX. I was thinking it was the new version of Mac OSX's problem, I had the same kind of problems happen on the 1st version IPad either. After I reinstalled, the computer became much more faster. But I

问题 I'm wanting to use a few JavaFX components in a Swing app (notably JFXPanel for its HTML 5 rendering support). My app is currently set up in Eclipse 4.3 (Kepler) and I have the latest Java 7 JDK installed on my machine. This tutorial from Oracle suggests that all you have to do is just refer to a JavaFX class and it'll work in a Swing app. So I type in JFXPanel panel = new JFXPanel() , but Eclipse does not recognize it as a valid Java class. It does recognize other Java 7 classes, like java

问题 We have some tests that had been working fine with JDK 1.6. We're now moving to JDK 1.7. These tests work fine in Eclipse. When we run these tests from our Ant build, we're seeing errors like this: junit.framework.TestListener: addError(<testmethodname>, loader constraint violation: when resolving overridden method "com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallerImpl.unmarshal(Lorg/w3c/dom/Node;)Ljava/lang/Object;" the class loader (instance of org/powermock/core/classloader

问题 How do I get a unique ID from a Path or File instance which must have an Inode or another unique ID in a "non Linux/Unix" filesystem? Can't find anything in the API, do I have to use JNI? Edit: I have two reasons: I want to have a unique mapping from a file in the filesystem to a tree-based representation in a database system. I want to detect renames of a file, which results in a deletion event and a new insertion event when watching a Path via WatchService (at least for Linux/Unix

问题 Is there any plan to leverage java 7 util.concurrent's ForkJoin APIs or, expose similar API in Akka? 回答1: We've been working with Doug Lea to improve ForkJoinPool for Akka, and I'm going to embed the new version for Akka 2.0: http://www.assembla.com/spaces/akka/tickets/1728 Read this for a summary from Doug: http://cs.oswego.edu/pipermail/concurrency-interest/2012-January/008987.html But we won't be exposing the raw API of ForkJoin, that's what the ForkJoin framework is for.

问题 I stuck here, we are using a licensed IBM Rational Application Developer V8.5 which contain WebSphere 8.5.0.0 as default to develop. As an old project which running on WebSphere need to update and including jdk update from 1.6 to 1.7 , the problem is WebSphere 8.5.0.0 only has jdk 1.6 as runtime version (As picture below, JVM 1.6_64 ), as showing in second picture, which means I don't have jdk 7 specific for RAD Websphere on my workspace. And I am not able to find downloading resource now.

问题 Im looking for a way to implement a timer event in Java SE 1.7, I don't want to use Swing timers as I have plans to port this application to Android. Background Im writing a LoginSession class that should generate an event when the session times out - this event should then be handled by a SessionManager class. I presume this a common enough requirement -I would expect there be a simple built in support for this but I can't seem to find it. 回答1: There is simple built-in support. Use Timer
