Eclipse Development Tips

1, you can create a new Quick Launch bat file in the Eclipse directory and set the appropriate startup parameters, such as minimum, maximum memory footprint [your Java_home directory]
Create bat file: Start ECLIPSE-VM c:/opensource/j2se.1.4/bin/javaw.exe-vmargs–xms256m-xmx768m
(Startup parameter setting: The Eclipse.ini file in the%eclipse_home% directory has the same effect)
Adjusts the size of the JVM, [12. 23 Supplements]
(1) The main purpose of using command-line parameters is to select the JVM type used by the Java program and the allocation policy of the JVM runtime heap memory
(2) We can set the size of the heap and the proportion of "new" and "old" through the command line parameters.
(3) Set-Xms and-xmx are equal in size to avoid resizing heap memory after each GC.


2, in order to support internationalization, the character set is generally set to UTF-8
Set Window/preferences/workbench/editors/text file Encoding:utf-8

3, in order to develop Java EE project must introduce the necessary library
Set Window/preferences/workbench/java/build path to select User libraries, click Add JARs ...
Add Extend Jar J2ee.jar
