WebLogic:

Http://www.bea.com.cn/products/beawebLogic/index.jsp
BEA Weblogic Platform includes BEA WebLogic Server, BEA WebLogic Portal, BEA WebLogic Integration, BEA WebLogic Workshop, Bea jrockit, is a first-class application platform suite for developers to use services to support their applications.
BEA WebLogic Server
BEA WebLogic Server is a scalable enterprise-level JAVA Platform Enterprise Edition (Java ee) application server. The Weblogic server infrastructure supports the deployment of various types of distributed applications and is also an ideal foundation for generating service oriented-based ubuntures (SOA) applications. SOA is a design methodology designed to maximize reuse of application services.
WebLogic Server fully implements the Sun Microsystems Java EE 5.0 specification and provides a set of standard APIs for creating Distributed Java applications that can access multiple services, such as databases, message transmission services, and connections to external enterprise systems. The end user client can use a web browser client or a Java client to access these applications. See programming model.
In addition to Java EE, WebLogic Server allows enterprises to deploy key task applications in a reliable, secure, highly available, and scalable environment. When a hardware fault or other fault occurs, enterprises can use these features to configure a Weblogic server instance cluster to allocate load and provide additional capacity. The new diagnostic tool allows the system administrator to monitor and adjust the performance of deployed applications and the WebLogic Server Environment itself. You can also configure WebLogic Server to automatically monitor and adjust application throughput without manual intervention. Extensive security functions protect access to services, protect enterprise data security, and prevent malicious attacks.
BEA WebLogic Portal
BEA WebLogic Portal 8.1 simplifies the production and management of Custom portals, so that users can use the shared service environment to promote changes with minimal complexity and effort.
BEA WebLogic Integration
BEA WebLogic Integration 8.1 integrates two completely different activities (Application assembly and application development) in other situations into a unified business integration solution.
Bea jrockit 5.0 JDK
With Bea jrockit 5.0 Java Development Kit (JDK), Java developers can deploy applications in production faster and more efficiently, and get the best performance with the least configuration. BEA WebLogic Express 10.0
BEA WebLogic Express 10.0 is a powerful and cost-effective servlet engine that can be started in the shortest time and run on the Weblogic product series. WebLogic Express allows you to quickly develop and start dynamic websites and basic web applications to provide you with the most reliable production ready deployment on the market.

First of all, they all support JSP server software. Differences: Tomcat: a free server software developed by the Apache Group Jakarta team. It is suitable for embedded in Apache and its source code can be obtained free of charge. The disadvantage is that its configuration is very troublesome, even if Apche is disconnected, and some security issues are not solved, beginners can use it to debug JSP files, but it is not appropriate to use it as a server for commercial applications. BEA WebLogic sever: it is a very powerful server software with simple configuration and powerful JSP extension. It comes with the JDBC driver of the database and supports JHTML, is currently the highest market share of the server, the latest version is 6.1, the price is very expensive, but hey ..... cracked version :) IBM WebSphere Application Server: it is a product of IBM and has powerful functions. It is also compatible with IBM development tools. It is very convenient to develop web programs, but the price is tens of thousands.

Tomcat usually exists in the development process. It is more convenient and smaller than other middleware for simple functions.
WebSphere is generally a production environment and is expensive. It is not practical for small projects, but is used by large systems of many large enterprises!

Tomcat is an open-source Web container that only supports some J2EE specification features, such as JSP/Servlet and JNDI. It must be used with other components to implement specific J2EE specification technologies, such as implementing JMS by integrating activemq, implement JTA through jotm JBoss is the complete implementation of J2EE specifications (the Web part is implemented by integrating Tomcat), open-source, and paid products. WebSphere and WebLogic commercial middleware fully support J2EE specifications and have their own unique core technologies.
