Question

运行tomcat服务器时出现此异常。我尝试更改-Xms和-Xmx，但没有运气。

我的项目是maven项目

我的系统RAM是8gb，我在bin文件夹中添加了“setenv.sh”文件并给出了像-Xms1024m -Xmx1024m这样的值BTW我的运行命令是

catalina.bat run -config conf / mySchema.xml

我注意到您正在调用catalina.bat而不是catalina.sh，因此您必须将Java选项放入bin / setenv.bat而不是setenv.sh。如果它不存在，请尝试创建一个，然后输入：

SET JAVA_OPTIONS=-Xms1024m -Xmx1024m

Answer 2

我已经解决了我的问题。问题是我有64位操作系统和64位tomcat 7.但是java 7是32位。

安装64位java 7后，问题就消失了。

谢谢大家！

在清单中添加以下行。

android:largeHeap="true"

请查看以下代码以便更好地理解。

 <application
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppThemeq"
    android:largeHeap="true">

exception：java.lang.OutOfMemoryError：Java堆空间
