Wow ,you are great ,David! I've got it! It must be a bug causing this problem that many guys did encounter. And when I changed the JDBC Connection after I reinstalled under the folder c:\j2,and clicked the save button,I find IT WORKS! A table displays in the portal Database Browser. Enclosed(to your inbox only) is the PrintScreen-picture for you to have a look at my time-consuming job under your help.
Thank you for your work.I think nobody would remedy this bug unless you. And any suggestion for me how to operate the database?Namelly,what should I do if I would like to creat a new table of my own application and make it display just as the demo? Thanks.
