Product Audience
This product is designed for developers who wish to create Web applications that incorporate live
maps and the tools needed to interact with those maps.
For experienced Java programmers, use the MapJ API to programmatically design custom maps
and functionality.
For novice Java programmers, we provide mapping functionality in the form of JavaBeans for easy drag and drop development in a visual IDE.
Even non-programmers can create prototypes of Web applications quickly with no programming by using the Web Application Builder. This tool walks you through the process of creating a mapping application that uses JavaServer Pages tags.
产品受众
这个产品专为那些希望去创建将实况地图和工具结合起来的Web应用程序的开发者而设计。
有经验的Java程序员使用MapJ API来编程设计自定义地图和其功能。
对于初学Java的程序员，我们在可视化的集成开发环境（IDE）下，以JavaBeans的简单的拖放来提供地图的绘制功能。
即使非编程人员也可以通过使用Web应用程序生成器，不编程而快速的建立Web应用程序原型。这个工具引导你通过创建使用JSP标签的地图应用程序的流程。
Features
MapXtreme Java is an enterprise-level application development tool based on the servlet architecture specified in the Java 2 Enterprise Edition. The key element of this product is MapXtremeServlet, a server-side component that manages the requests and responses for mapping services, including image requests (GIF, JPEG), vector data requests (query methods), and metadata requests (table information).
By using a servlet architecture, MapXtreme Java can focus on satisfying mapping requests, while the web server/servlet container handles other server-side issues such as load balancing, security, and fault tolerance. Additionally, the servlet model uses HTTP, the standard for communicating across the Internet. Other features of MapXtreme Java include:
? Sophisticated mapping capabilities such as selection behavior, theme mapping and analysis, and advanced labeling and rendering.
? Data source access through JDBC that allows you to maintain your spatial data on a secure RDBMS, yet still use it to its full potential to build maps.
? Conveniences for easier installation and configuration, development and deployment, such as JavaBeans, Web Application Builder, JSP custom tag library, sample applications, and Apache Web Server/Tomcat servlet container.
特色
MapXtreme Java是一个基于J2EE中的servlet架构的企业级应用程序开发工具。它的关键元素是MapXtremeServlet，MapXtremeServlet是管理地图服务的请求和响应的服务器端的组件。这些请求包括图片请求（GIF, JPEG），矢量数据请求（查询方法）和元数据请求（表格信息）。
通过使用servlet架构，当web服务器/ servlet 容器处理其他的服务器端的问题（比如负载平衡，安全，容错）时，MapXtreme Java能够集中于满足地图映射的请求。此外，servlet模型使用通过Internet通信的HTTP标准。MapXtreme Java的其它特点有：
? 先进的绘图功能，比如选择行为，主题映射和分析，以及先进的标签技术和渲染技术。
? 通过JDBC获得的数据源可以充分发挥其潜力来建立地图。JDBC可让你的空间数据保持在一个安全的数据库管理系统上。
?方便容易的安装、配置、开发、调用一些组件，比如JavaBeans，Web应用程序生成器，JSP自定义的标签库，示例应用程序，Apache的Web服务器/Tomcat servlet容器。
