java -Xbootclasspath的用法.
昨晚使用eclipse的时候突然想到eclipse怎样去区分使用jdk1.4还是jdk1.5,我使用jdk1.4在eclipse运行一个java程序这时的command是 C:\j2sdk1.4.2_05\bin\javaw.exe -Xbootclasspath:C:\j2sdk1.4.2_05\lib\tools.jar;C:\j2sdk1.4.2_05\jre\lib\rt.jar;C:\j2sdk1.4.2_05\jre\lib\sunrsasign.jar;C:\j2sdk1.4.2_05\jre\lib\jsse.jar;C:\j2sdk1.4.2_05\jre\lib\jce.jar;C:\j2sdk1.4.2_05\jre\lib\charsets.jar;C:\j2sdk1.4.2_05\jre\lib\ext\dnsns.jar;C:\j2sdk1.4.2_05\jre\lib\ext\ldapsec.jar;C:\j2sdk1.4.2_05\jre\lib\ext\localedata.jar;C:\j2sdk1.4.2_05\jre\lib\ext\sunjce_provider.jar -classpath E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\classes;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\jtds-1.0.3.jar;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\poi-2.5.1-final-20040804.jar;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\poi-contrib-2.5.1-final-20040804.jar;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\poi-scratchpad-2.5.1-final-20040804.jar;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\commons-logging-1.0.2.jar;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\log4j-1.2.6.jar -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,suspend=y,address=localhost:1160 com.dengyin.data.transform.DoingTxt 红色部分后面的那些包是在eclipse重设置好的.这是使用这些包作为启动类.(
set search path for bootstrap classes and resources )然而当我使用jdk1.5的时候的command是 C:\jdk1.5.0_03\bin\javaw.exe -classpath E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\classes;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\jtds-1.0.3.jar;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\poi-2.5.1-final-20040804.jar;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\poi-contrib-2.5.1-final-20040804.jar;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\poi-scratchpad-2.5.1-final-20040804.jar;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\commons-logging-1.0.2.jar;E:\Eclipse_WorkSpace\Eclipse_Work\DateTransform\lib\log4j-1.2.6.jar -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,suspend=y,address=localhost:1635 com.dengyin.data.transform.DoingTxt 我们看到这时并没有-Xbootclasspath参数,我们知道java程序中的所有依赖的类都会去classpath里面照.这时我想-Xbootclasspath做的工作应该时被javaw.exe做了,把那些系统必须的那些bootClass设置到了bootClasspath里面了.(以上想法时我个人的猜测,我上网找了但是没有找到满意的答案) 当你装好了jdk1.5时,它会拷贝一份java.exe到windows(winNt)目录下面,这样你就可以不用设置JAVA_HOME然后把%JAVA_HOME%\bin放到系统的path目录了, 而且这时java.exe会自己设置好bootClass,这样你就不用在系统的环境变量里面设置ClassPath了.
-Xbootclasspath:<directories by="" separated="" files="" and="">
set search path for bootstrap classes and resources
-Xbootclasspath/a:<directories by="" separated="" files="" and="">
append to end of bootstrap class path

[options] is any combination of the options listed below. The options
are optional and may appear in any order; <idl file=""> is required and
must appear last.

server, all, serverTIE, allTIE. serverTIE and allTIE
cause delegate model skeletons to be emitted. If this
flag is not used, -fclient is assumed.

included files. This option adds another directory.
-keep If a file to be generated already exists, do not
overwrite it. By default it is overwritten.
-noWarn Suppress warnings.
