Recently, we have migrated the JBoss server to the WebSphere server. At the beginning, we were too optimistic. We thought it was an application server in the J2EE architecture, which should be 1 ~ It took us nearly two weeks to complete the work within two days. There are many typical problems encountered during the migration process, so I think it is necessary to
First, the application pointTomcat is a servlet container provided by the Apache Foundation that supports Java EE key technologies such as JSP, servlet and JDBC, so users can use Tomcat to develop Web applications based on database, servlet, and JSP pages, which is no problem.However, Tomcat is not an EJB container; in other words, Tomcat does not support one of the important techniques of the Java EE, EJB. Then, Web applications developed using EJB components cannot run under Tomcat. As we all
Jboss as 7 cannot initialize a spring bean when deploying a Web application (this problem does not occur under Tomcat)The reason is that the Web application does not have a jar package that imports JBoss support for springWorkaround:Download Snowdrop-vfs.jar(the file is in the Jboss-spring-subsystem-as7-nodeps-2.0.0.final.zip package module-deployer\org\
JBoss has a default data source Defaultds, and he uses the JBoss built-in HSQLDB database. In practical applications you may use different databases, such as MySQL, MSSQLServer, Oracle, and so on. Data source configuration templates for various databases you can find in the Jboss installation directory]/DOCS/EXAMPLES/JCA directory, the default name is: Database n

When multiple JBoss services are started on one service, the ports may conflict. If you modify the default ports one by one, it will be complicated; for this reason, JBoss provides a unified method for managing multiple instances (servicebindingmanager), the basic idea is that JBoss provides a server port binding file-xxx-bindings.xml, it defines multiple ports m
The ejb3.0 application must run in JDK or later versions.The ejb3.0 application needs to run in the EJB container. The javaee Application Server contains the Web Container and EJB container.
The ejb3.0 application requires the following Java EE application servers:JBoss (4.2.x or later)WebLogic (version 10 or later)
Note: currently, Tomcat is only a Web Container and cannot run EJB applications.
