For work relations, you can use DB2 and jdbcto connect to the db2java.zip package imported to the db2client.DB2 supports type2 and type4 in JDBC connection 4. The difference between them is that you need to configure the DB2 client in type2 mode.Your program will find the server correctly, and type4 will not be needed.
The method of type2 is very simple, as long

From: Richard Choi (Richard in JLUBBS)E-mail: richardchoi@126.comThere are many articles on JDBC connection to DB2 databases, such as "JDBC database connection Daquan" and "JSP DB2 Connection database". Although they are all very detailed information, it is also said that it solves the problems not solved by our predec
This article mainly introduces the description of the correct DB2 JDBC connection operation method and the actual application code. We all know that there are many articles about the JDBC connection of the DB2 database, well-known include "JDBC database connection Daquan" an
