hi, i am new to J2ME. I was wondering to know if there is a microbrowser for J2ME or J2ME itself is a microbroswer. I am thinking to do a project related with J2ME. I need details of what things to be used and where to start.Sorry, If I am asking for more but I dont have any other option.

I want to build this project based on the following paper:


and the abstract of this paper is as follows:

The wireless web provides users with anytime, anywhere access to the information. A new service like location based shopping is also facilitated by ubiquitous web access because of mobile use. To realize wireless web services, web content must be practical and adapt to a mobile user�s dynamic context. Mobile users have limited capacity devices when compared to desktop users and sometimes requires different information, formats or media. XML based technologies let context aware wireless services adapt their content to a user�s situation. Based on visitor�s context- for example, location, information interests and device capabilities � the system retrieves data from a content server. The system uses the W3C�s Document Object Model (DOM) API to generate an XML tree-like structure, and Extensible Style Sheet Language Transformations (XSLT) to generate wireless Markup Language (WML) or HTML content for display on mobile devices.

This approach follows a context-aware computing system which allows users to specify their context, or mobile devices and infrastructures must be able to automatically sense context (which requires beacons or Infra red sensors or GPS to sense the user location).
The web content for wireless web services can be generated from the HTML pages the user accesses on the wired internet or directly from the content databases that store source data. This approach of generating the web content relies on database content as it is more reliable to present on the mobile terminals device screen. So, the first step is to retrieve the requested content from the database, extract the context data for the user and environment, and then convert the content to an XML tree. The XML representation, referred to as the DOM, depends on the values of the retrieved context parameters. Using as XSLT processor which specifies the style sheet document�s format, XML documents are converted into other data formats such as HTML, XHTML, or WML.

I could not figure out a way where to start and I would appreciate if some one could help me with where to start and what tools to be used.

Thank You in advance
