Dear all,
I am moving my web application fro XP to Linux platform. Now I have a few questions for that;
First, the system in Linux. I have tomcat, jdk as the follows:
/usr/jdk/j2sdk1.4.2_06
/export/home/dfflab/jakarta-tomcat-4.1.31
When I first tried to recompile my java classes, it said:
javac *.java
SeahorseAction.java:3: package javax.servlet.http does not exist
import javax.servlet.http.*;
^
SeahorseAction.java:4: package org.apache.struts.action does not exist
import org.apache.struts.action.*;
^
SeahorseAction.java:5: package org.apache.struts.action does not exist
import org.apache.struts.action.ActionForward;
^
SeahorseAction.java:14: cannot find symbol
symbol: class Action
public class SeahorseAction extends Action {
^
SeahorseAction.java:15: cannot find symbol
symbol : class ActionMapping
location: class coreservlets.SeahorseAction
public ActionForward execute(ActionMapping mapping,
^
SeahorseAction.java:16: cannot find symbol
symbol : class ActionForm
location: class coreservlets.SeahorseAction
ActionForm form,
^
SeahorseAction.java:17: cannot find symbol
symbol : class HttpServletRequest
location: class coreservlets.SeahorseAction
HttpServletRequest request,
^
SeahorseAction.java:18: cannot find symbol
symbol : class HttpServletResponse
location: class coreservlets.SeahorseAction
HttpServletResponse response)
^
SeahorseAction.java:15: cannot find symbol
symbol : class ActionForward
location: class coreservlets.SeahorseAction
public ActionForward execute(ActionMapping mapping,
^
SeahorseFormBean.java:3: package org.apache.struts.action does not exist
import org.apache.struts.action.*;
^
SeahorseFormBean.java:5: cannot find symbol
symbol: class ActionForm
public class SeahorseFormBean extends ActionForm {
^
SeahorseAction.java:27: cannot find symbol
symbol : class HttpSession
location: class coreservlets.SeahorseAction
HttpSession session = request.getSession();
Do I need install something else? Do I need to install apache in Linux? ( I just installed Tomcat in XP box and my application works.) The PATH from 'export' coomand is like this:
declare -x PATH="/dfflab/jakarta-tomcat-4.1.31/bin:/export/home/dfflab/jakarta-tomcat-4.1.31/common/lib/servlet.jar:/export/home/dfflab/jakarta-tomcat-4.1.31/common/lib/struts.jar:/export/home/dfflab/jakarta-tomcat-4.1.31/common/lib/mysql-connector-java-3.0.14-production-bin.jar"
2) To get around these compile errors, I first change my java code in XP sso the URL for the database points to the new location and compiled, then I just copy those classes into the Linux box. But when I run it, it said:
ClassNotFoundException: com.mysql.jdbc.Driver
So I guess I need to put the "mysql-connector-java-3.0.14-production-bin.jar" in another place. As you see, previously in XP box I put it in the "WEB-INF/lib/" directory of the web application. That works in XP box.
I got no clue what to do. Please help!
P.S. I do some search and one post said if I put the "mysql-connector-java-3.0.14-production-bin.jar" in the 'jre/lib/ext' of the jdk directory, it would solve this issue. But I don't have the permission to copy to that directory.
I also put the mysql-connector-java-3.0.14-production-bin.jar in the "WEB-INF/lib" directory of the web application and I think that should be the standard way to put any reources (jar, zip files) for your application.
Thanks.

Hi,
set the CLASSPATH of all '.jar' files (which files to need to compile/run the program) at the command line. ex: servlet.jar,struts.jar,etc.,
and copy the Struts.jar file to the WEB-INF/lib directory of the web application for runtime.

Hi, Vidya
Thanks for your reply. I already got it after 'exporting' those jar files in the 'CLASSPATH'.
