Oracle Java JVM中的主配置文件在哪里？

Question

Where is main config file in the Oracle Java JVM?

I need to hardcode some config to the JVM, like config:

javax.xml.accessExternalSchema=all
http.proxyHos=proxy
http.proxyPort=8080
javax.net.ssl.trustStore=c:/qqq

I tried to write it to the management.properties, but it doesn't helped...

Answer 1

The JAVA_TOOL_OPTIONS environment variable allows you to set options like system properties globally in your environment. This means they will be picked up by every java command invokation.

Answer 2

System.setProperties(properties object);

This will set the system properties.

If you want to set a specified property, then use

System.setProperty(key, value);//Both key and value should be string.

NOTE: This will first check the permission and then set it. If permission denied, then SecurityException may occur.

I am not sure you are looking for the same or not, but you can modify deployment.properties which is under below location in Windows:

C:\\Users\\user-name\\AppData\\LocalLow\\Sun\\Java\\Deployment

Note: Change the user-name with your userName.

Have a look on the below link:
