这是我的ivy.xml:

我的资源文件夹中有不同的strings.xml文件(values,values_fr,values_de ...),我想在运行时加载其他翻译.是否可以将新字符串添加到这些文件中,即使它已经被编译了？或者有解决方法吗？

我正在运行带有Tomcat的Eclipse 3.5(从WTP集成),我希望在txt中看到输出日志而不仅仅是控制台

无法在我的eclipse /工作区或本地Tomcat 6安装目录中找到它

任何线索如何启用这些？

我也启用org.apache.catalina.valves.RequestDumperValve了输出并在控制台上滚动,我希望在txt中看到

我开始3个mongod在不同的每个过程port不同dbpath.

./bin/mongod --replSet foo/tauquir:27018,tauquir:27019 --rest
./bin/mongod --port 27018 --dbpath /data/db1 --replSet foo/tauquir:27017 --rest
./bin/mongod --port 27019 --dbpath /data/db2 --replSet foo/tauquir:27017 --rest

开始连接为:

CONN = Connection("tauquir:27017", slave_okay=True)
CONN.admin.command("replSetInitiate")
CONN = Connection(["tauquir:27018", "tauquir:27019"])

追溯我得到:

     CONN.admin.command("replSetInitiate")
              File "/usr/local/lib/python2.6/dist-packages/pymongo-1.9-py2.6-linux-
        i686.egg/pymongo/database.py", line 293, in command msg, allowable_errors)
              File "/usr/local/lib/python2.6/dist-packages/pymongo-1.9-py2.6-linux-

OperationFailure(msg % response["errmsg"])
            pymongo.errors.OperationFailure: command SON([('replSetInitiate', 1)]) failed:

我有以下实体:

@Entity
public class AnalysisPolicy extends PersistentEntity{
    private Set nodeIds;


@ElementCollection(fetch = FetchType.EAGER)
@CollectionTable(
        name="analysis_policy_nodes",
        joinColumns=@JoinColumn(name="analysis_policy_id")
)
@Column(name="node_id")
public Set<Long> getNodeIds() {
    return nodeIds;
}
Run Code Online (Sandbox Code Playgroud)

}

select p from AnalysisPolicy p where p.nodeIds is not empty

并尝试以下JPQL查询:

10:11:16,665 DEBUG [org.hibernate.hql.ast.AST] --- SQL AST ---
 -[SELECT] QueryNode: 'SELECT'  querySpaces (AnalysisPolicy,analysis_policy_nodes)

任何人都可以告诉我为什么以下代码

function s3()

   function ret = fun(x)
       disp(x);
       ret = 0;
   end

  fun(1);

end

产生"尝试引用非结构数组的字段".我在一个名为s3.m的文件中有这段代码.如果我使用播放按钮在编辑器中运行它,它运行正常.如果我在命令行输入s3.m,则会产生上述错误.在此先感谢您的帮助!

我可以轻松使用索引值吗？我认为使用自然索引值比使用类更好.我想以这种方式使用.index.

HTML

<div id="test">
<ul>
<li>Im index 0</li>
<li>Im index 1</li>
<li>Im index 2</li>
<li>Im index 3</li>
</ul>
</div>

伪(Jquery)Javascript

$('#test ul > li').index(2).hide();

$('#test ul > li').index(1).click(function() {
 alert('lulz you clicked the li with the index value of 1 bro');
});

我没有找到如何使用.index值以这种方式工作的线索..是否可以使用此方法轻松工作？

给定二叉搜索树和目标值,找到总计达目标值的所有路径(如果存在多个路径).它可以是树中的任何路径.它不必来自根.

例如,在以下二叉搜索树中:

  2
 / \ 
1   3 

当总和应为6时,1 -> 2 -> 3应打印路径.

是否有可能在Facebook中嵌入我自己的视频播放器,因此我可以直接在时间轴中看到视频,就像所有YouTube视频一样？

我需要在网站的<head>部分中包含任何元标记吗？

我有一个层次结构,链接嵌套在list元素中,如下所示:

<ul>
    <li><a href="#">Page 1</a>
        <ul>
            <li><a href="#">Page 1.1</a></li>
            <li><a href="#">Page 1.2</a>
                <ul>
                    <li><a href="#">Page 1.2.1</a></li>
                    <li><a href="#">Page 1.2.2</a></li>
                </ul>
            </li>
            <li><a href="#">Page 1.3</a></li>
        </ul>
    </li>
    <li><a href="#">Page 2</a>
        <ul>
            <li><a href="#">Page 2.1</a></li>
            <li><a href="#">Page 2.2</a></li>
        </ul>
    </li>
    <li><a href="#">Page 3</a>
        <ul>
            <li><a href="#">Page 3.1</a>
                <ul>
                    <li><a href="#">Page 3.1.1</a></li>
                    <li><a href="#">Page 3.1.2</a></li>
                </ul>
            <li><a href="#">Page 3.2</a></li>
            <li><a href="#">Page 3.3</a></li>
                <ul>
                    <li><a href="#">Page 3.1.1</a></li>
                    <li><a href="#">Page 3.1.2</a></li>

基本上只是一个站点地图.但是我想用jQuery创建下一个和上一个链接,jQuery找到你正在访问的活动页面(可能通过检查一个类),并找到上一个和下一个锚元素(不考虑层次结构).我已经试过next(),previous()并且find()但似乎无法得到它的工作.

获取当前锚元素之前和之后的最简单方法是什么？
