tomcat or weblogic

本文探讨了Tomcat作为纯粹的动态页面服务器的特点及其代码的高标准。同时对比了JBoss提供的全套开源J2EE解决方案,并提及JBoss实际上集成了多个项目,其动态页面服务部分与Tomcat相似。此外,还讨论了Weblogic作为高性能和高稳定性的商业软件的优势。
Tomcat:只是一个单纯的动态页面服务器项目。它的最大意义在于它的代码最符合标准,它只是实现一个优雅的动态页面服务器,并没有其它目的。
JBoss:开源,软件免费,收费的是服务。JBoss 提供全套的开源 J2EE 解决方案,整合了若干项目。动态页面服务部分其实就是一个 Tomcat。
Weblogic:本身强调的是性能和稳定性等,是一套完整的商业软件。

如Dr_juio 所说,WebLogic和Tomcat根本就不是一个等级的。就像用一台服务器和一个 CPU 比较。
### Tomcat Server Default Index.html Configuration and Behavior In the context of a web application deployed on Apache Tomcat, when accessing an application's root URL or any directory within it without specifying a file name, Tomcat looks for specific files to serve as the welcome page. The `index.html` is one such file that can be served automatically. The behavior regarding which files are considered welcome pages comes from the deployment descriptor (`web.xml`) located either globally in `$CATALINA_BASE/conf/web.xml` or specifically per-web-application inside each app’s own `WEB-INF/web.xml`. This configuration contains a `<welcome-file-list>` element defining what files should act as index files[^1]. For instance: ```xml <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> </welcome-file-list> ``` When deploying applications using embedded Tomcat instances through frameworks like Spring Boot, similar configurations apply but might also involve programmatic setup rather than just XML-based definitions[^2]. For example, adding servlet mappings programmatically does not directly affect how `index.html` gets loaded unless explicitly configured otherwise via equivalent mechanisms provided by these higher-level abstractions over raw Tomcat APIs. Regarding performance issues mentioned elsewhere concerning both Tomcat and other Java EE servers like WebLogic, while relevant to overall server operation efficiency, they do not pertain directly to loading static resources such as HTML documents at startup time under normal circumstances[^3]. Finally, understanding lifecycle methods involved during connector initialization provides insight into various stages where custom logic could potentially influence resource serving behaviors including those related to default document handling; however, this aspect primarily concerns dynamic aspects more so than simple static content delivery processes associated with `index.html`. --related questions-- 1. How does configuring multiple welcome files impact request processing order? 2. What role does the global versus local placement of `web.xml` play in determining welcome-page precedence? 3. Can Spring Boot properties override standard Tomcat settings for setting up welcome files? 4. In what scenarios would someone need to customize the list beyond typical entries like `index.html`, `index.jsp` etc.? 5. Are there security implications tied to exposing certain types of files as defaults?
