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，我什至更改了 netbeans.conf 中的堆大小，但它仍然显示相同的错误.我怎样才能避免这种情况发生?

解决方案

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

正确的方法是在项目上右击，选择属性"，然后运行"；在那里您可以适当地设置 VM 选项(例如，-Xmx256m).它应该看起来像这样:

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?

exception 

javax.servlet.ServletException: Servlet execution threw an exception

root cause 

java.lang.OutOfMemoryError: Java heap space

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.9 logs.

解决方案

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

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:
