问题又始于IE与Firefox
试问你用一个最新版的Firefox去与远古级的IE6做比较有意义么,
可是偏偏有许多人喜欢这么去比较,借此来宣传Firefox.
马克思说了很多费话,但还是有一句说的蛮对的,我们要辩证地看待事物.
刘翔他跑了世界冠军破了世界纪录也与我无关,
临场退赛也与我无关,他跑了第一也不代表黄种人就怎么怎么样了
我一直用IE 我也用Firefox 我也用Chrome 我也用Safari
我也不用杀毒软件,我也不中木马病毒.
我就知道,倒卖大蒜,白痴都能挣钱,我也知道,程序员同样龙鱼混杂.我们很少听到龙啸,看到的都是鱼在冒泡.
每天都是IE与Firefox ,Windows与Linux, C与Java

新安装了一个FlexBuilder3
可是在运行 Application的时候 报出
CreateProcess: "%ProgramFiles%\Internet Explorer\iexplore.exe" G:\java\Flex\........html error=2
Error=2好像是Windows系统返回的错误
且不去管他. ~
打开Eclipse的--Preferences---General---Web Browser---将Default system Web browser 修改成Internet Explorer或Firefox
问题得以解决 `~
至此问题原因 也很明了
因为我的系统已经使用了很多年了~ Windows默认的是IE6吧~ 已经早就升级成了IE8 但是参数Default Web Browser应该还是指向IE6 , 所以出了问题~~
与Eclipse无关~~

Unable to load configuration. - bean - jar:file:/F:/Web/homesite/jsp/struts/WEB-INF/lib/struts2-convention-plugin-2.1.8.jar!/struts-plugin.xml

因为在32位操作系统上执行了如下的操作
alter system set sga_max_size=2G scope=spfile;
之后再重启数据库就会失败
报出错误:
ORA-27102
Out of Memory
解决的方法也很简单:
新建一个文本文件 如initaaa.ora
内容：
SPFILE='../product/10.2.0／db_1/dbs/spfileorcl.ora'
sga_max_size=1073741824
保存之后
如是启动数据库：
SQL>startup pfile=$ORACLE_HOME/dbs/initaaa.ora
启动成功之后就可以把之前的错误参数修改过来了
对于Spfile损坏或者丢失的情况
可以删除原来的Spfile,然后利用系统中备份的pfile 来创建一个新的Spfile
SQL>CREATE SPFILE FROM PFILE='.\pfile\init.ora.83200715416'
------------------------------------------------------------------------------------------------------------------------------------------------------
其他命令(转):
//查看Oracle以pfile还以Spfile方式启动
SQL>Select isspecified,count(*) from v$spparameter group by isspecified;
如果isspecified里有true，表明用spfile进行了指定配置
如果全为false，则表明用pfile启动
//查看Spfile的路径
SQL>show parameter spfile
//从spfile获取pfile
SQL>Create pfile='d:pfileSID.ora' from spfile;
SQL>Create pfile='d:pfileSID.ora' from spfile='spfile_location';
//从pfile获取spfile
 SQL>Create spfile from pfile='Your_pfile_location'
SQL>Create spfile='spfile_location' from pfile='Your_pfile_location'
//动态修改参数
SQL>alter system set parameter=Value scope=spfile|both|memory
Startup nomount的时候需要读去spfile或pfile,两者共存，spfile优先
//强制用pfile启动
SQL>startup pfile='Your_Pfile.ora'
SQL>startup spfile='/data/oracle/product/10.2.0/db_1/dbs/dbs/spfile_mqq.ora' force
从Date类型中取形如 20091201 字符串
function getDate(s_date) {
var str_date = new Array();
str_date.push(s_date.getFullYear());
str_date.push(s_date.getMonth() < 9 ? "0" + (s_date.getMonth() + 1)
: (s_date.getMonth() + 1));
str_date.push(s_date.getDate() < 10 ? "0" + s_date.getDate() : s_date
.getDate());
return str_date.join("");
}
//查找字符串中的逗号
var s = "aa,bb,cc,"
//方法一
var count =0;
a.replace(/[,]/g,function(){
count=count+1;
return "a";
}
)
alert(count);
//方法二
var r = a.split(",");
r.pop();
alert (r.length);
//方法三
alert(a.replace(/[^,]/g,'').length);
