以前用的eclipse-jee因为在部署项目过程中总是出现bug被我删除。今天去eclipse官网又下了一个Eclipse IDE For Java EE Developers。
版本是:eclipse-jee-helios-SR1-win32.zip
我的jdk版本是:1.6.0_20
解压后启动,发现弹出提示框“ Failed to create the Java Virtual Machine”
针对这个问题在网上寻找解决方案。找到几个,全是Ctrl c/v,不带半句解释。
后来,靠着差强人意的有限英语水平,在eclipse官网的论坛搜索,发现此问题是一bug。
“The Java bug was closed for voting and comments at 6969236 on the Java BugParade because the change has been reverted; the related Eclipse bug report is open for oting and comments at bug 319514. ”-引用eclipse官网
在修复版本推出之前它提供了一个解决方法:
打开eclipse目录下的eclipse.ini文件,修改–launcher.XXMaxPermSize属性,其中此属性有两处
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.1.R36x_v20100810
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m
将其值改为128m即可,如下。(事实上,只改后面一个就可以,启动eclipse时以后者为准)
-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.1.R36x_v20100810
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
128M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
128m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m
然后就可以成功启动。
Eclipse调试Java程序出现Socket closed.(cannot connect to VM)错误,
如果在用eclipse调试(或运行)java程序时,出现了cannot connect to VM 错误,实在找不出什么原因,可以检查以下几个方面。
1、如果在linux系统下,要把127.0.0.1 localhost 加到配置文件中(更改hosts文件)。
2、如果在XP系统下,请检查杀毒软件的防火墙。
3、经过我测试,在安装卡巴斯7.0后eclipse调试java项目时就有可能出现上述错误,就算你退出卡巴也不行,只能御载。
4、但卡巴6.0和8.0没有问题!!
