问题 I am facing issue with Hibernate. Using Hibernate 3.2.6 and JDK 1.7.0_21 Is this issue coming due to JDK compatibility with Hibernate version? This issue is random. I still unable to find steps to reproduce. 2014-07-14 06:09:10,661 [DEBUG] EventExpenseAreaService.getEventSummary:654 - Revenue Value (Hari) --> 1166.15 2014-07-14 06:09:18,665 [ERROR] EventSetupService.getEventById:1451 - java.lang.Boolean cannot be cast to java.lang.String java.lang.ClassCastException: java.lang.Boolean cannot

问题 I have created a class that dynamically compiles, loads in a CustomClassLoader, and executes an in-memory java source (i.e.: without class files) java source by invoking it's main method. I need to capture the StdOut , StdIn , and StdErr , although it's not possible doing so in my current code. ( Compiler API + Classloader + Reflection ) My requirements might be the same as asked in this question - and as suggested by the accepted answer - use java.lang.Process. This is easier if I had

问题 Trying to install Java EE 7/Glassfish 4 on OS 10.9 Mavericks and it crashes every time. I have tried installing the Apple JDK and the Oracle JDK and neither work. Has anyone ran into this? I remember installing on 10.8 and it worked just fine. Thanks!

问题 We're developing in java 7 and YouTube Data API v3. When we are calling the upload service with "processingDetails" part, we are getting a 503 Service Unavailable Error. What are we doing wrong? If we remove it, we can upload the video just fine. But we want/need to know about processingDetails. Here is the code: YouTube.Videos.Insert videoInsert = this.youtube.videos().insert("snippet,statistics,status,processingDetails", videoObjectDefiningMetadata, mediaContent); everything else it's the

问题 When reading the answer to this question, I was wondering how Java7 bootstrap knows about the presence of public static void main(String[] args) method, without running the static initializers ? I have some assumptions on this topic, but some of them is obviously wrong: Java Bootstrap is running in JVM, so it can only use standard JVM features (no native features) - the called class must be on CLASSPATH, for example The standard JVM classloading is done via the normal classloading mechanism

问题 As i understand it, Java 7's suppressing exceptions feature is an automatic one. In other words, exceptions happening in what used to be a finally block in 6 are automatically suppressed in favor of exception that took place upon resource allocation. So, in this example things may go wrong with a) opening a resource and b) closing a resource or c) possibly both. As i understand it, Java 7 will throw exception that took place upon opening, whom we can ask to give us suppressed exceptions,

问题 We recently configured our Oracle database to be in so-called native encryption (Oracle Advanced Security Option). As development goes on, some SQL queries are sometimes badly-written and so an error should be returned by the JDBC driver ( ojdbc7 v12.1.0.2 ). Instead of that, a Checksum Fail IOException is raised. So the problem is that we do not have anymore any syntax or database integrity error at all. The problem is the same in SQL GUI editors, like DBeaver , SQLDeveloper or SQuirrel .

问题 I got this error when creating a final double using underscores to make the double more readable. It was declared in a run() method. public void run() { final double nanoSeconds = 1_000_000_000.0 / 60.0; } I'm using IntelliJ IDEA 12. 回答1: In IntelliJ IDEA you have to change Project language level in project settings to 7.0 level: 回答2: Yes..you need to change the default language level settings if you are using and IDE. For IntelliJ users it is under File --> Project Structure --> Projects.

问题 Is there any way where I can increase the Java Compiler Compliance level of Eclipse 3.5 to 1.7. (i.e.) By adding a plugin/add-on. Since by default this will not support the JDK 1.7 compliance. We have a constraint in Eclipse upgrade, since it's an RCP application. Any thoughts on this will be greatly appreciated. Thank You. 回答1: Old eclipse version doesn't support java 7. You will have to download at least eclipse-3.8M1 version. 回答2: To conclude, there is no way to enable Java 7 Compliance in
