    1. 某個service的參數(shù)有復雜對象時，如果要用默認的beanmapping，記得這個對象要有的默認構(gòu)造器(空參數(shù)構(gòu)造器)，不然Axis在處理的時候會所有的字段都是同一個值..至于原因我沒搞清楚-,-~~
    2. 不要用List，盡量用數(shù)組!
    ValueBean[]?getValues()?
    ????    {?
    ????????ArrayList?result?    =?new?ArrayList();?
    ????????    return?(ValueBean[])?result.toArray();?
    ????}
    上面的代碼還是會出問題，要用iterator一個一個map過去
    public?class?ValueHelper?
    ????    {?
    ????????    public?static?ValueBean[]?toArray(List?values)?
    ????????    {
    ????????????ValueBean[]?result?    =?new?ValueBean[values.size()];?
    ????????????Iterator?i?    =?values.iterator();?
    ????????????    int?i?=?0;?
    ????????????    while?(i.hasNext())?
    ????????????    {?
    ????????????????ValueBean?value?    =?(ValueBean)?i.next();?
    ????????????????result[i    ++]?=?value;?
    ????????????}    ?
    ????????????    return?result;?
    ????????}    ?
    ????}    ?
    ????ValueBean[]?getValues()?    {?
    ????????ArrayList?result?    =?new?ArrayList();??
    ????????    return?ValueHelper.toArray(result);?
    ????}
    3. 要生成符合ws-i的web service最好用document/literal
    <service name="MyWebRes" provider="java:RPC" style="document "use="literal">

    用起來還是很簡單，唯一要注意的是用Axis生成Web Service的時候記得在global configuration里面改一下
    <parameter name="sendMultiRefs" value="false"/>

    ie下的話也有一個webservice.htc，沒仔細研究過..

    1. private constructor
    2. static getInstance
    3. syncronized..waste a lot of time
    4. double check..modified syncronize, so time-waste might occurs only when first time the instance construct
