工作学习 / IT技术讨论 / java程序中装载DB2 通用JDBC 驱动程序的问题，很急很急1。想在java程序中访问db2数据库（windows平台），是不是可以选择type 4：db2 Universal JDBC driver?或者应该选别的type？
2。编译通过后，为什么运行时语句Class.forName("com.ibm.db2.jcc.DB2Driver");总是报错说找不到class：com.ibm.db2.jcc.DB2Driver？（已经import java.sql.*;)
拜托有java＋db2经验的朋友指点一下，多谢！

1.只有UDB8有type 4 driver. UDB 7 only has type 2 and type 3 driver. 2. Check your classpath, DB2install/sqllib/java/db2jave.zip should be in your classpath

多谢！那是不是说我可以用type 2，如果只做application的话？是com.ibm.db2.jdbc.app.DB2Driver吗？还有，db2java.zip在那里，没问题。

哎呀，换成com.ibm.db2.jdbc.app.DB2Driver还是报找不到class！这个class应该在哪个目录下呢？我的db2java.zip文件是在你说的目录下面。

app driver is included in db2java.zip. Did you check your classpath? db2java.zip should be included in your classpath.

Windows Start menu "Run"->cmd-> set clssspath=db2installfolder/sqllib/java/db2java.zip;%CLASSPATH%-> set classpath-> check the output->java YOURAPPLICATION

after i set it and run set classpath to check output, i found that there's two settings about db2java.zip. so i guess this classpath has already been there beore. but why java still couldn't find class?

How do you run your java program?If you are using IDE, another story.

i compiled java source code with tool TextPad. then run java program in cmd. btw, i checked the classpath in environment setting(win2000), db2java.zip has been there.

是不是说要查autoexec.bat里面的classpath呀

把这个path写到你的classpath 里。
