# Define inside web.xml
Open `$CATALINA_BASE/conf/web.xml` and find this:

```xml
&lt;!-- ==================== Default Session Configuration ================= --&gt;
&lt;!-- You can set the default session timeout (in minutes) for all newly   --&gt;
&lt;!-- created sessions by modifying the value below.                       --&gt;

&lt;session-config&gt;
    &lt;session-timeout&gt;30&lt;/session-timeout&gt;
&lt;/session-config&gt;
```

All webapps implicitly inherit from this default web descriptor. You can override these default settings via your webapp&#39;s own `web.xml` file.

This is actually from my Tomcat 7 (Windows) but I think Tomcat 5.5&#39;s configuration is not very different

I have an input defined as

    &lt;input class=&quot;datepicker&quot; type=&quot;text&quot; ng-model=&quot;clientForm.birthDate&quot; /&gt;

Which is rigged up to be displayed elsewhere on the page:

    &lt;tr&gt;
        &lt;th&gt;Birth Date&lt;/th&gt;
        &lt;td&gt;{{client.birthDate|date:&#39;mediumDate&#39;}}&lt;/td&gt;
    &lt;/tr&gt;

When the page loads the birth date is nicely formatted as something like `Dec 22, 2009`. However, when I look inside my `&lt;input&gt;` it&#39;s shown as `Tue Dec 22 2009 00:00:00 GMT-0800 (Pacific Standard Time)` which I guess is how JS renders `Date` objects as strings.

Firstly, how do I tell Angular to show the date in the `&lt;input&gt;` as something like `12/22/2009`? I can&#39;t seem to apply `|filters` inside the `ng-model` attribute.

Secondly, as soon as I edit the date, even keeping it in it&#39;s original format, my other text (inside the `&lt;td&gt;`) doesn&#39;t seem to apply the `|date` filter anymore; it suddenly changes formats to match that of the input textbox. How do I get it to apply the `|date` filter every time the model changes?

How to format a date using ng-model?

So I have the next force layout graph code for setting nodes, links and other elements:


    var setLinks = function ()
    {
        link = visualRoot.selectAll(&quot;line.link&quot;)
            .data(graphData.links)
            .enter().append(&quot;svg:line&quot;)
            .attr(&quot;class&quot;, &quot;link&quot;)
            .style(&quot;stroke-width&quot;, function (d) { return nodeStrokeColorDefault; })
            .style(&quot;stroke&quot;, function (d) { return fill(d); })
            .attr(&quot;x1&quot;, function (d) { return d.source.x; })
            .attr(&quot;y1&quot;, function (d) { return d.source.y; })
            .attr(&quot;x2&quot;, function (d) { return d.target.x; })
            .attr(&quot;y2&quot;, function (d) { return d.target.y; });

        graphData.links.forEach(function (d)
        {
            linkedByIndex[d.source.index + &quot;,&quot; + d.target.index] = 1;
        });
    };


    var setNodes = function ()
    {
        node = visualRoot.selectAll(&quot;.node&quot;)
            .data(graphData.nodes)
            .enter().append(&quot;g&quot;)
            .attr(&quot;id&quot;, function (d) { return d.id; })
            .attr(&quot;title&quot;, function (d) { return d.name; })
            .attr(&quot;class&quot;, &quot;node&quot;)
            .on(&quot;click&quot;, function (d, i) { loadAdditionalData(d.userID, this); })
            .call(force.drag)
            .on(&quot;mouseover&quot;, fadeNode(.1)).on(&quot;mouseout&quot;, fadeNode(1));
    };

    //append the visual element to the node
    var appendVisualElementsToNodes = function ()
    {
        node.append(&quot;circle&quot;)
            .attr(&quot;id&quot;, function (d) { return &quot;circleid_&quot; + d.id; })
            .attr(&quot;class&quot;, &quot;circle&quot;)
            .attr(&quot;cx&quot;, function (d) { return 0; })
            .attr(&quot;cy&quot;, function (d) { return 0; })
            .attr(&quot;r&quot;, function (d) { return getNodeSize(d); })
            .style(&quot;fill&quot;, function (d) { return getNodeColor(d); })
            .style(&quot;stroke&quot;, function (d) { return nodeStrokeColorDefault; })
            .style(&quot;stroke-width&quot;, function (d) { return nodeStrokeWidthDefault; });

        //context menu:
        d3.selectAll(&quot;.circle&quot;).on(&quot;contextmenu&quot;, function (data, index)
        {
            d3.select(&#39;#my_custom_menu&#39;)
              .style(&#39;position&#39;, &#39;absolute&#39;)
              .style(&#39;left&#39;, d3.event.dx + &quot;px&quot;)
              .style(&#39;top&#39;, d3.event.dy + &quot;px&quot;)
              .style(&#39;display&#39;, &#39;block&#39;);

            d3.event.preventDefault();
        });
        //d3.select(&quot;svg&quot;).node().oncontextmenu = function(){return false;};

        node.append(&quot;image&quot;)
            .attr(&quot;class&quot;, &quot;image&quot;)
            .attr(&quot;xlink:href&quot;, function (d) { return d.profile_image_url; })//&quot;Images/twitterimage_2.png&quot;
            .attr(&quot;x&quot;, -12)
            .attr(&quot;y&quot;, -12)
            .attr(&quot;width&quot;, 24)
            .attr(&quot;height&quot;, 24);

        node.append(&quot;svg:title&quot;)
            .text(function (d) { return d.name + &quot;\n&quot; + d.description; });
    };


Now, the colors and size dependencies changed and I need to redraw the graph circles (+all appended elements) with different color and radius. Having problem with it.

I can do this:

    visualRoot.selectAll(&quot;.circle&quot;).remove();

but I have all the images that I attached to `&#39;.circles&#39;` still there.

In any way, any help will be appreciated, let me know if the explanation is not clear enough, I will try to fix it.

P.S. what is the difference between `graphData.nodes`  and `d3.selectAll(&#39;.nodes&#39;)`?

I want to customize the activity back button in action bar, not in hard key back button. I have overriden the `onBackPressed()` method. It works with my emulator back button, but not with action bar back button. 

I want it to happen with action bar. How can I do this?

Here is my code:

	@Override
	public void onBackPressed()	{
        Toast.makeText(getApplicationContext(),&quot;Back button clicked&quot;, Toast.LENGTH_SHORT).show(); 
        return;
	}
I have used this toast whether back pressed is working or not but the actual implementation changes like to move back to previous activity. But this is not working with the button present on top of action bar (besides title of the activity).

Please any one could specify me the problem.

I want to remove square brackets from a string, but I don&#39;t know how.

    String str = &quot;[Chrissman-@1]&quot;;
    str = replaceAll(&quot;\\[\\]&quot;, &quot;&quot;);
    
    String[] temp = str.split(&quot;-@&quot;);
    System.out.println(&quot;Nickname: &quot; + temp[0] + &quot; | Power: &quot; + temp[1]);

But my result is: [Chrissman | 1]
The square brackets doesn&#39;t get removed.

I tried using a different regex: `&quot;\\[.*?\\]&quot;`, `&quot;\\[\\d+\\]&quot;`
but the result is the same, the square brackets still attached on the string.

Edit:

I tried:

    str.replaceAll(&quot;]&quot;, &quot;&quot;);
    str.replaceAll(&quot;[&quot;, &quot;&quot;);

And now I&#39;m getting:

    Exception in thread &quot;Thread-4&quot; java.util.regex.PatternSyntaxException: Unclosed character class near index 0

Is it possible to append a single character to the end of `array` or `string` in java. Example:

        String otherString = &quot;helen&quot;;

I&#39;m completely lost regarding the differences between the `initLoader` and the `restartLoader` functions of the `LoaderManager`:

- They both have the same signature. 
- `restartLoader` also creates a loader, if it does not exist (&quot;Starts a new or restarts an existing Loader in this manager&quot;). 

Is there some relation between the two methods? Does calling `restartLoader` always call `initLoader`? Can I call `restartLoader` without having to call `initLoader`? Is it safe to call `initLoader` twice to refresh the data? When should I use one of the two and **why**?

How do I configure `CATALINA_HOME` as an environment variable and how do I run Tomcat server under Windows 7?

How to set CATALINA_HOME variable in windows 7?

I was trying to add Tomcat 7 in my Eclipse in Ubuntu. When I click &quot;Add new server&quot; in Eclipse and select &quot;Tomcat v7.0 Server&quot;, the field &quot;Server Name&quot; is blank and I cannot type in anything in that textbox as shown below:

![Eclipse Add Tomcat Server][1]

What I did before is I deleted a Tomcat 7 server from Eclipse and I was trying to reinstall Tomcat 7. But it doesn&#39;t allow me to type anything in that textbox and I cannot proceed to the &quot;Next&quot; button. My environment is Ubuntu Linux and Eclipse for JavaEE.

I am using the manager app in tomcat 7,
and i am unable to undeploy an application completely.

It says 
`FAIL - Unable to delete [F:\apache-tomcat-7.0.33\webapps\balaji]. The continued presence of this file may cause problems.`

I read somewhere its because of some phenomenon called memory leak , and if we fix it the issue will be solved.

Can anyone tell me what is this memory leak in tomcat 7, and how can we fix it ??
I am using windows 7 OS.
If i am able to fix it will my un-deploy and re-deploy process run smooth ?


How to prevent file locking when undeploying a Tomcat web app?

I&#39;m trying to get Appfuse + Tomcat + jRebel working.

Appfuse by default uses Cargo to download tomcat (ver. 7.0.33) and deploy the application to it. I wish to use an already installed tomcat (ver. 7.0.27) instead of the downloaded one. I made the change following the [appfuse FAQ][1].

After deploying with `mvn cargo:run`, how can I know that the actual running tomcat is indeed 7.0.27? 

I used to type a wrong URL (ex. *localhost:8080/dfsfsdf*) to see it in the error page, but now it shows nothing.

My `$CATALINA_HOME` points to my own tomcat 7.0.27.
sorry forgot to mention, it&#39;s for Windows.


Update:

Since this question had become somehow popular, I would like to explain why that accepted answer. simple, it was the first one which solved my problem. 

I am looking at the title of the question,  [@Tech Junkie][2] and [@CPU 100][3] really have the best answer, but not for the scenario I was encountered. (I was wanting to know if `mvn cargo:run` runs my installed tomcat or a &quot;project embeded&quot; tomcat)  `:)`
