请问我要在servlet中调用javabean怎样做呢？servlet在classes/servlet下login.class
javabean在classes/test下test.class

[sparkwu]

Try it:
login.java must add line -> import test.test;

[sunkay]

上面的方法试过好像不行哦

[print]

跟我遇到的问题一样，，帮你顶了。。

[sparkwu]

Try it package into *.jar
put in D:\Tomcat 4.1\webapps\project_name\WEB-INF\lib
If can't solve this trouble, Please show error mesage.

以下是login.java的部分代码从中调用faq.class它们都放在同一个目录

package test;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import java.sql.*;

public class login extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=GBK";
/**Initialize global variables*/
public void init()throws ServletException {
faq work1=new faq();
}
。。。。。。

faq.java如下：
package test;
import java.sql.*;
public class faq {
//JDBC-ODBC 桥
String sDBDriver = "sun.jdbc.odbc.JdbcOdbcDriver";
String sConnStr = "jdbc:odbc:faq";
Connection conn = null;
ResultSet rs = null;
public faq() {
try {
Class.forName(sDBDriver);
}
catch(java.lang.ClassNotFoundException e) {
System.err.println(e.getMessage());
}
}
//定义public型函数
public ResultSet executeQuery(String sql) {
rs = null;
try {
conn = DriverManager.getConnection(sConnStr);
Statement stmt = conn.createStatement();
rs = stmt.executeQuery(sql);
}
catch(SQLException ex) {
System.err.println("aq.executeQuery: " + ex.getMessage());
}
return rs;
}
}
//----------------------
出现错误提示为：
C:\Program Files\Apache Tomcat 4.0\webapps\test\WEB-INF\classes\test>javac login
.java
login.java:13: cannot resolve symbol
symbol : class faq
location: class test.login
faq work1=new faq();
^
如何解决？？？？？？？？？？？？？？？？？？

编译的时候指定classpath

[sunkay]

请问怎样在编译的时候指定classpath？？

[huangjiuyt]

D:\Tomcat 4.1\webapps\project_name\WEB-INF\test\faq.class
在login.java中import test.*；

[ejb99666]

把login.java 中的 package test ; 去掉，
加入 import test;
试试先。

出错提示跟没改一样呀
