Google Static Map

A new component in JSOS - proxy for Google Static Map. The Google Static Maps API lets you embed a Google Maps image on your webpage without requiring JavaScript or any dynamic page loading. Bit it requires a key (free registration on Google). And this API key is connected with some domain. So if you are distributing your map it could be a problem – map will be actually requested from some other domain. This proxy lets you always perform request from your domain (domain associated with key):

Just describe servlet and mapping:



and now you can request static map by this way:

http://your_host/servlet/staticmap?key=your_key&maptype = mobile&markers = 40.8403347,-82.2393255 &size=240x320&zoom=16

P.S. original component used for this custom proxy is generic HTTP proxy.

MySQL GIS Extension

MySQL GIS Extension tutorial.

Lets you add a special column for your latitude/longitude data tables - geometry. Then you create an index on that column called a spatial index. This is really an R-Tree index that is very fast when you’re doing range queries.
You want to use MySQL's GIS because spatial indexes are faster for latitude/longitude range queries than regular indexes.

Resources in web applications

A couple of components let you unpack resources in your web applications on the fly. The main idea is to pack various resources (images, css and js files) together with your code and extract data on the fly. Could be useful for example when you distribute application on the USB and your application should be up and running without installation – everything will be packed in one file.

Resource servlet lets you pickup resources (getResourceAsStream) from CLASSPATH and Unzip servlet lets you directly extract data from zip (jar) file. For example:

1. Pack your images (directory /pic) in file myfile.jar
2. Describe servlet and mapping:

Alternatively, you can define path via mapping. Set zip (jar) file as an initial parameter and define mapping for files you need to unzip:



And now in your JSP files you can write so for example:

<img src="http://your_host/pic/a.gif"/>

file a.gif will be extracted on the fly

Twitter for teachers published an interesting compilation of Twitter tools for teachers. It is always good when the conservative source (and education is so, in general) adopts hot technology. And twice good of course, they've mentioned one of our mashups – Annotated links. Lets you share links with own remarks (post-it notes).

We can suggest for the teachers check out also another mashup – Secure notes. Lets you share one time readable text notes. So for students for example there is no way to share teacher's answers with friends etc. :-)

Links in the list are really interesting. Check out for example GroupTweet – group communications via Twitter

Coldtags suite ver. 3.80

Coldbeans Software announced the major new release of Coldtags suite. This suite provides over 380 JSP custom tags for common programming tasks faced by JSP developers.

Coldtags suite comes with a wide range out of the box ready-to-use the most common control components that are repeatedly required for the development of JEE applications. They include standard user interface components like buttons, lists, edits, grids, menus, tables, tree views, calendars, ajax etc. With this suite developers and web designers no need to worry about writing browser-specific HTML or JavaScript.

All controls are carefully written and tested to operate equally well on major Internet browsers as well JEE servers.

Actually at this moment this collection is the biggest repository of the reusable web components for JSP (and/or Coldfusion) developers.

See it here:

Mashup has been integrated with two previous applications for data discovery: Twitter links and Twitter info.

Base 36 shortner

How does the typical URL shortening service work? One of the most often used solutions deploys Base 36 encoding.

Base 36 is a positional numeral system using 36 as the radix. So for example decimal 10 is A in Base 36, decimal 100 is 2S, decimal 1000 is RS etc.

The choice of 36 is convenient in that the digits can be represented using the Arabic numerals 0-9 and the Latin letters A-Z. Base 36 is therefore the most compact case-insensitive alphanumeric numeral system using ASCII characters.

So shortening service at the first step replaces an original URL:


with a new one:


where ID could an unique value from some sequence. E.g. it could be an auto-incremented key from database. And on the second step we can encode this ID with Base 36 and make it much shorter.

And here is a custom JSP taglib, lets you perform shortening: Base 36 taglib.
