see the "User Comments" feature available. We register a user, send a comment:
So we put the ASP code:
Copy Code code as follows:

Microsoft VBScript run-time error ' 800a000d '
Type mismatch: ' Execute '
/test/dlog/log_mdb/%29dlog_mdb%29.asp, line 1266
Note: When we submit code to the database, the code content cannot be too large. So we use

EJB: the business logic component. in J2EE, the business logic is basically implemented by the EJB component and the WebService interface is released externally (of course, using open-source frameworks that comply with JAX-WS specifications can be done without EJB ).
Therefore, although EJB was born for a long time, it is not out of date, but many people are discouraged from it, which has a lot to do with its own reasons.
The difference in JNDI between EJB and different containers leads to vario
