声明：ant,weblogic 都用的是weblogic自带的jdk1.4
1， 运行-cmd-ant，javac 就报内存溢出

elcipse中ant打包时内存溢出的解决方法:
设置其参数设置见我上一篇日志。

解决方法：

一：WebLogic配置问题：
由于WebLogic的配置问题，我们的测试出现了失败情况。原因是为WebLogic分配的内存太少了。通过修改commom/bin/commEnv.cmd文件来增加内存分配。
修改的部分如下：
:bea
if "%PRODUCTION_MODE%" == "true" goto bea_prod_mode
set JAVA_VM=-jrockit
set MEM_ARGS=-Xms768m -Xmx1024m
set JAVA_OPTIONS=%JAVA_OPTIONS% -Xverify:none
goto continue
:bea_prod_mode
set JAVA_VM=-jrockit
set MEM_ARGS=-Xms768m -Xmx1024m//原来是128M~256M，太小了，数据太大
goto continue
结果修改后，没有效果。还是有失败的情况。
发现，原来，在：bea下面还有一段配置信息如下：
:sun
if "%PRODUCTION_MODE%" == "true" goto sun_prod_mode
set JAVA_VM=-client
set MEM_ARGS=-Xms768m -Xmx1024m -XX:MaxPermSize=256m
set JAVA_OPTIONS=%JAVA_OPTIONS% -Xverify:none
goto continue
:sun_prod_mode
set JAVA_VM=-server
set MEM_ARGS=-Xms768m -Xmx1024m -XX:MaxPermSize=256m
goto continue
将这里的内存分配修改后见效。
原因是，上面对第一段代码是为bea自己的JVM设置的，下面的是为Sun的设置的。而WebLogic默认的是Sun的，所以出了毛病。
-------------------------另注：------------------------------
startWeblogic.cmd
文件中调用的是 commEnv.cmd，
在此文件中设定内存大小，可以生效。
call "%WL_HOME%/common/bin/commEnv.cmd"
问题解决了。
[javac] The system is out of resources.
[javac] Consult the following stack trace for details.
[javac] java.lang.OutOfMemoryError
BUILD FAILED
file:F:/eclipse/workspace/biz/src/build.xml:150: Compile failed; see the compile
r error output for details.

在javac的选项里增加 fork="true" memoryMaximumSize="512m"来加在编译时的内存
用eclipse 开发，在用ant编译web工程时，碰到java.lang.OutOfMemoryError: Java heap space异常
解决办法：
方法1、window->preferences->java->installed jres->edit jre 把default vm arguments 的参数设为-Xms64m -Xmx512
方法2、在window的环境变量中添加JAVA_OPTS=-Xms64m -Xmx512 问题解决
2，然后我再eclipse中ant打包，
