Depends on what you want to do. The fourth and sixth methods there won&#39;t reload any form data, they essentially make a separate visit to the page. Some versions of Firefox also have issues with the third method. Other than that, I&#39;d go with the fifth as a personal preference. It seems the clearest.

You may also do:

`wd` represents **window** || **document**: 

 - **wd.location.assign(wd.location.href)** : 
*go to the URL*
 - **wd.location.replace(wd.location.href)** :
*go to the URL and replace previous page in history*
 - **wd.location.reload(&amp;lt;true/false/blank&amp;gt;)** : *reload page from server/cache/cache*

I&#39;m trying to write a custom servlet (for AJAX/JSON) in which I would like to reference my `@ManagedBeans` by name. I&#39;m hoping to map:

`http://host/app/myBean/myProperty`

to: 

    @ManagedBean(name=&quot;myBean&quot;)
    public class MyBean {
        public String getMyProperty();
    }

Is it possible to load a bean by name from a regular servlet? Is there a JSF servlet or helper I could use for it?

I seem to be spoilt by Spring in which all this is too obvious.

I am going through a socket program. In it, `printStackTrace` is called on the `IOException` object in the catch block.  
What does `printStackTrace()` actually do?

	catch(IOException ioe)
	{
		ioe.printStackTrace();
	}

I am unaware of its purpose. What is it used for?

which way to reload a current page (using a button) would you prefer?

    1 &lt;input type=&quot;button&quot; value=&quot;Reload&quot; onClick=&quot;history.go(0)&quot;&gt;
    2 &lt;input type=&quot;button&quot; value=&quot;Reload&quot; onClick=&quot;location.reload(true)&quot;&gt;
    3 &lt;input type=&quot;button&quot; value=&quot;Reload&quot; onClick=&quot;window.location.reload(true)&quot;&gt;
    4 &lt;input type=&quot;button&quot; value=&quot;Reload&quot; onClick=&quot;window.location.href=window.location.href&quot;&gt;
    5 &lt;input type=&quot;button&quot; value=&quot;Reload&quot; onClick=&quot;document.location.reload(true)&quot;&gt;
    6 &lt;input type=&quot;button&quot; value=&quot;Reload&quot; onClick=&quot;document.location.href=document.location.href&quot;&gt;

As the URL of the page changes frequently AFAIK a &#39;fallback function&#39; like

    &lt;a href=&quot;urlOfCurrentPage.html&quot; onclick=&quot;window.location.reload(true);return false;&quot;&gt;Reload&lt;/a&gt;

won&#39;t work for me, right?

Is there a set of things that every JavaScript programmer should know to be able to say &quot;I know JavaScript&quot;?

What should every JavaScript programmer know?

The code below displays a Google map and search results when you enter an address and hit the submit button.  I&#39;ve been playing with it to try
and force the page to completely refresh or reload once you hit the submit button.  But I can&#39;t get it to work right.  It loads the results &quot;in page,&quot; but I&#39;d like the page to completely refresh when the results load, like when you hit the back button on your browser.  Hope that makes sense.

I think the answer lies in this line of code but I don&#39;t know jquery very well.  It&#39;s near the bottom of the full code below.

How to force page refreshes or reloads in jQuery?

I&#39;m creating a new engine for a rails 3 application. As you can guess, this engine is in the lib directory of my application.

However, i have some problems developing it. Indeed, I need to restart my server each time I change something in the engine.

Is there a way to avoid this ?

Can I force rails to completely reload the lib directory or a specific file and his requirements for each request ?

Thanks for your help :)

How can I refresh a page with jQuery?

Earlier it was working fine. I have been playing little bit config. So may be i have changed some config unknowingly.   

here is config of environment/development.rb

      config.cache_classes = false

      # Log error messages when you accidentally call methods on nil.
      config.whiny_nils = true

      # Show full error reports and disable caching
      config.consider_all_requests_local       = true
      config.action_view.debug_rjs             = true
      config.action_controller.perform_caching = false

      # Don&#39;t care if the mailer can&#39;t send
      config.action_mailer.raise_delivery_errors = false

      # Print deprecation notices to the Rails logger
      config.active_support.deprecation = :log

      # Only use best-standards-support built into browsers
      config.action_dispatch.best_standards_support = :builtin

      # migration prefix with sequence #s
      config.active_record.timestamped_migrations = false

      #time zone
      config.time_zone = &#39;UTC&#39;

Here is config section of application.rb

     # Configure the default encoding used in templates for Ruby 1.9.
     config.encoding = &quot;utf-8&quot;

     # Configure sensitive parameters which will be filtered from the log file.
     config.filter_parameters += [:password]

     config.active_record.schema_format = :sql


when i run reload! on rails console it return true

Rails Console: reload! not reflecting changes in model files? What could be possible reason?

I would like to implement a JavaScript code which states this:
if the page is loaded completely, refresh the page immediately, but only once.
I&#39;m stuck at the &quot;only once&quot;:

    window.onload = function () {window.location.reload()}

this gives a loop without the &quot;only once&quot;. jQuery is loaded if this helps.
