企业开发JAVAEE项目用什么集成开发环境？

公司开发JAVAEE项目用哪种集成开发环境比较多？Eclipse、MyEclipse还是NetBeans？

请问一个Eclipse javaee开发工具的问题，不是MyEclipse

我用MyEclipse的时候，只要往lib里面复制jar包，就会自动进入classpath，可是在Eclipse jee里面却不行，不知道有何办法，谢谢

Tomcat启动时报错了，严重: Error filterStart

Tomcat启动的时候报错了，严重:Error filterstart. 但是我去掉web.xml的所有filter的配置后，Tomcat启动正常。 详细信息：[code="java"] 2009-08-18 09:24:43,671 INFO [org.hibernate.hql.ast.ASTQueryTranslatorFactory] - Using ASTQueryTranslatorFactory 2009-08-18 09:24:43,687 INFO [org.hibernate.cfg.SettingsFactory] - Query languag e substitutions: {} 2009-08-18 09:24:43,687 INFO [org.hibernate.cfg.SettingsFactory] - JPA-QL strict compliance: disabled 2009-08-18 09:24:43,703 INFO [org.hibernate.cfg.SettingsFactory] - Second-level cache: enabled 2009-08-18 09:24:43,718 INFO [org.hibernate.cfg.SettingsFactory] - Query cache: disabled 2009-08-18 09:24:43,718 INFO [org.hibernate.cfg.SettingsFactory] - Cache region factory : org.hibernate.cache.impl.NoCachingRegionFactory 2009-08-18 09:24:43,734 INFO [org.hibernate.cfg.SettingsFactory] - Optimize cach e for minimal puts: disabled 2009-08-18 09:24:43,750 INFO [org.hibernate.cfg.SettingsFactory] - Structured se cond-level cache entries: disabled 2009-08-18 09:24:43,765 INFO [org.hibernate.cfg.SettingsFactory] - Echoing all S QL to stdout 2009-08-18 09:24:43,781 INFO [org.hibernate.cfg.SettingsFactory] - Statistics: d isabled 2009-08-18 09:24:43,781 INFO [org.hibernate.cfg.SettingsFactory] - Deleted entit y synthetic identifier rollback: disabled 2009-08-18 09:24:43,796 INFO [org.hibernate.cfg.SettingsFactory] - Default entit y-mode: pojo 2009-08-18 09:24:43,812 INFO [org.hibernate.cfg.SettingsFactory] - Named query c hecking : enabled 2009-08-18 09:24:43,890 INFO [org.hibernate.impl.SessionFactoryImpl] - building session factory 2009-08-18 09:24:44,468 INFO [org.hibernate.impl.SessionFactoryObjectFactory] - Not binding factory to JNDI, no JNDI name configured 2009-08-18 09:24:44,984 INFO [org.springframework.jdbc.datasource.DriverManagerD ataSource] - Loaded JDBC driver: com.microsoft.sqlserver.jdbc.SQLServerDriver 2009-08-18 09:24:45,390 INFO [org.springframework.web.context.ContextLoader] - R oot WebApplicationContext: initialization completed in 4656 ms 2009-8-18 9:24:45 org.apache.catalina.core.StandardContext start 严重: Error filterStart 2009-8-18 9:24:45 org.apache.catalina.core.StandardContext start 严重: Context startup failed due to previous errors 2009-08-18 09:24:45,937 INFO [org.springframework.web.context.support.XmlWebAppl icationContext] - Closing org.springframework.web.context.support.XmlWebApplicat ionContext@354749: display name [Root WebApplicationContext];
