Java Forum / General / January 2007Connect to db2/400 through jsp
Hello, I am new to jsp. Could someone please help me out. I have successfully connected to db2/400 through java in WDSC. I am connecting db2/400 through jsp in WDSC. I am using com.ibm.as400.access.AS400JDBCDriver. The following exception is thrown:- java.lang.ClassNotFoundException: com.ibm.as400.access.AS400JDBCDriver I have included the jt400.jar in java classpath. It's in Java Source folder. The jsp file is in WebContent->WEB-INF->jsp file Thanks Regards Savita > Hello, > I am new to jsp. Could someone please help me out.

Hello, The jt400.jar is installed in :- Dynamic Web Projects/Projectname(test)/Java Resources/JavaSource/jt400.jar If jt400.jar has to be pkaced in WEB-INF ,ho winstall .jar file here?

I do not know - with tomcat, I'd simply put the file there myself.

It is a basic fact of (JEE) Web applications that JARs used by the app go into the application's WEB-INF/lib/ directory, just like it is a basic fact that individual packages/classes go into the WEB-INF/classes directory and the deployment descriptor is WEB-INF/web.xml. <http://tomcat.apache.org/tomcat-5.5-doc/appdev/deployment.html> and you can google around for more from Sun, IBM and so on. How you get the JARs into the right directory can be by "copy" (Win), "cp" (Linux), Ant (all platforms), graphical interfaces to the file system, your favorite IDE and so forth. Eclipse and Netbeans, for example, will build the JARs where they belong if you call them "libraries" in the project properties. - Lew > How you get the JARs into the right directory can be by "copy" (Win), > "cp" (Linux), Ant (all platforms), graphical interfaces to the file > system, your favorite IDE and so forth.

Not only that, as a workaday programmer one must conform to the deployment procedures of one's employer, which can sometimes seem quite rococo. - Lew Hello, " I am connecting to db2/400 through jsp in WDSC" I have put jt400.jar in the folllowing directory:- C:\Documents and Settings\Administrator\IBM\rationalsdp6.0\workspace\test1\WebContent\WEB-INF\lib Then to I am getting the error : java.lang.ClassNotFoundException: com.ibm.as400.access.AS400JDBCDriver In the follwing directory (JavaSource) I have set classpath =C:\Program Files\IBM\Client Access\jt400\lib\jt400.jar C:\Documents and Settings\Administrator\IBM\rationalsdp6.0\workspace\test1\JavaSource The java jdbc code connects to db2/400 fine. The jsp file is not getting the jt400.jar file. The server used here is AS400 server.

AS400* server? > Then to I am getting the error : > java.lang.ClassNotFoundException: com.ibm.as400.access.AS400JDBCDriver .. > The server used here is AS400 server. Is it a test or production server? One good way to 'refresh' a server is to restart it, but that might not be a good option for a production server. ( * Ultimately, you may actually need to RTFM of your AS400 server ) Andrew T. > " I am connecting to db2/400 through jsp in WDSC" > [quoted text clipped - 5 lines] > Then to I am getting the error : > java.lang.ClassNotFoundException: com.ibm.as400.access.AS400JDBCDriver If you are using WebSphere Application Server then try put the jar in WEB-INF\lib in the war and redeploy the war.
