java.lang.OutOfMemoryError：使用NetBeans的Java堆空间 [英] java.lang.OutOfMemoryError: Java heap space with NetBeans

问题描述

这是我在NetBeans启动的Tomcat servlet容器实例中运行Web应用程序时遇到的错误。为了解决这个问题，我甚至改变了netbeans.conf中的堆大小，但它仍然显示相同的错误。如何防止这种情况发生？

This is the error I get when I run my web application in an instance of the Tomcat servlet container started by NetBeans. To fix this I even changed the heap size in netbeans.conf, but still it shows the same error. How can I keep this from happening?

java.lang.OutOfMemoryError: Java heap space

推荐答案

在netbeans.conf中更改堆大小只会更改NetBeans本身的堆，而不是应用程序通过NetBeans运行。

Changing the heap size in netbeans.conf only changes the heap for NetBeans itself, not for applications run through NetBeans.

正确的方法是右键单击项目并选择属性，然后选择运行;在那里你可以适当地设置VM选项（例如， -Xmx256m ）。它看起来应该是这样的：

The correct way is to right-click on the project and select "Properties" and then "Run"; there you can set the VM options appropriately (-Xmx256m, for instance). It should look something like this:
