Start contact J2EE, the following records the daily learning. On November 22nd, I came into contact with J2EE, of course, a lot of knowledge of theory, boring but essential! Installing the WebLogic server, the main thing is to configure environment variables, some of them are updated, PATH, CLASSPATH, JAVA_HOME, and then change the two variables of Windows to the T directory under WIN, mainly The three JAR included in the OK. Test passed! On November 23, it was a bunch of messy theory, and there were two self-written components, JSP. Test passed! On November 24th, it was a bunch of theory. In the afternoon, write code, set the buffer pool in WebLogic, configure a data source, modify the method in Server in the JSP, so you can do not disclose the code, give the user two interfaces, IP, port, users can call methods, note: a data source called OracleBean, not necessarily an Oracle database, a name! Then self-write one program, the BEAN method in the C-terminal, implements the registration, login function, of course, the code in S is unknown. The program is wrong, because the time is too late, the test is not completed, and you must get it before tomorrow.
