我试图用apache tomcat代理安装openam 12 war,如配置sso.But尝试了五十多次,但我只得到错误.

如果我将以下属性值更改为来自webagent的amAdmin,则在tomcat第二个实例中调用受保护的应用程序时,它会一次又一次地重定向到同一页面,但没有得到任何异常.amAdmin是我的openam控制台的管理员用户.

如果它有另一个数组的元素,有没有其他更好的方法从一个数组中删除重复项？

<script>
var array1 = new Array("a","b","c","d","e","f");
var array2 = new Array("c","e");

for (var i = 0; i<array2.length; i++) {
    var arrlen = array1.length;
    for (var j = 0; j<arrlen; j++) {
        if (array2[i] == array1[j]) {
            array1 = array1.slice(0, j).concat(array1.slice(j+1, arrlen));
        }
    }
}
alert(array1);

</script>

我想要一个函数来转换Bigdecimal 10.12 for 10.12345和10.13 for 10.12556.但是没有功能同时满足两种转换.请帮助实现这一目标.

以下是我的尝试.
值10.12345:

BigDecimal a = new BigDecimal("10.12345");

a.setScale(2, BigDecimal.ROUND_UP)
a.setScale(2, BigDecimal.ROUND_CEILING)
a.setScale(2, BigDecimal.ROUND_DOWN)
a.setScale(2, BigDecimal.ROUND_FLOOR)
a.setScale(2, BigDecimal.ROUND_HALF_DOWN)
a.setScale(2, BigDecimal.ROUND_HALF_EVEN)
a.setScale(2, BigDecimal.ROUND_HALF_UP)

输出:

10.12345::10.13
10.12345::10.13
10.12345::10.12
10.12345::10.12
10.12345::10.12
10.12345::10.12
10.12345::10.12

值10.12556:

BigDecimal b = new BigDecimal("10.12556");

b.setScale(2, BigDecimal.ROUND_UP)
b.setScale(2, BigDecimal.ROUND_CEILING)
b.setScale(2, BigDecimal.ROUND_DOWN)
b.setScale(2, BigDecimal.ROUND_FLOOR)
b.setScale(2, BigDecimal.ROUND_HALF_DOWN)
b.setScale(2, BigDecimal.ROUND_HALF_EVEN)
b.setScale(2, BigDecimal.ROUND_HALF_UP)

输出:

10.12556::10.13
10.12556::10.13
10.12556::10.12
10.12556::10.12
10.12556::10.12
10.12556::10.12
10.12556::10.12

虽然我的所有源代码都在正确的包中.但是在构建项目时找不到它.通常它显示链接的一切.但是在Build Project或Autobuild时直接运行项目.

The import ecnet.rd.config cannot be resolved 

就像它显示所有内部imports.But外部导入,如从JAR文件导入正在工作.

PS:

我的Eclipse最近崩溃了,但之后运作良好,再一次发生了这种事情.

请帮忙找到解决这个问题的方法.

任何人都可以帮我找到JAVA中方法的返回类型.我试过这个.但不幸的是它不起作用.请指导我.

 Method testMethod = master.getClass().getMethod("getCnt");

  if(!"int".equals(testMethod.getReturnType()))
   {
      System.out.println("not int ::" + testMethod.getReturnType());
   }

输出:

不是int :: int

请帮助我理解为什么第二个块抛出错误但是第一个块正在运行.两个地方的限制小于声明的大小(41).

Declare
  Type typ_int_array IS VARRAY(41) OF NUMBER;
  v_typ_int_array typ_int_array := typ_int_array(10,20,30,40);
BEGIN
  SYS.DBMS_OUTPUT.PUT_LINE(v_typ_int_array(1));
  v_typ_int_array.extend(6);
  v_typ_int_array(6) := 60;
END;

Declare
  Type typ_int_array IS VARRAY(41) OF NUMBER;
  v_typ_int_array typ_int_array := typ_int_array(10,20,30,40);
BEGIN
  SYS.DBMS_OUTPUT.PUT_LINE(v_typ_int_array(1));
  v_typ_int_array.extend(38);
  v_typ_int_array(38) := 60;    
END;

例外:

我正在努力在Java中生成JSON String.

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;

JSONArray ja = new JSONArray();
JSONObject js = new JSONObject();
JSONObject j = new JSONObject();

String s = "[{\"shakil\",\"29\",\"7676\"}]";

js.put("id", "1");
js.put("data", s);
ja.add(js);

j.put("rows", ja);

System.out.println(j.toString());

实际产量:

{"rows":[{"id":"2","data":"[{\"shakil\",\"29\",\"7676\"}]"}]}

预期产量:

{"rows":[{"id":"2","data":["shakil", "29","7676"]}]};

在NAME表中,FIRST列具有null但未选择任何行.请帮我理解.

SELECT * FROM NAME WHERE FIRST != '1'

我知道过滤器用于处理请求,可以使用http header和httpmethods做事,但我很困惑

clientrequestfilter和containerrequestfilter有什么区别？在哪种情况下我们必须使用clientrequestfilter和containerrequestfilter？

我试过这个网站,但没有任何关于此的细节.

请帮我理解这个.

我正在尝试使用Apache Camel Bindy创建一个固定文件阅读器,但我得到了异常.请帮助我找到解决方案.没有页眉和页脚,这是运行良好.
