こんにちは、私はストラットでプログラムを実行しているときにストラットを初めて使用しました。このようなエラーが発生しました。

mycodeは次のようになります......InsertModel.java

package com.cac.struts;
import java.sql.*;
public class InsertModel
{
    public boolean insert(String name,String branch,int regd)
    {
        boolean b=false;
        try
        {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            Connection con=DriverManager.getConnection("jdbc:odbc:mohit","system","rock");
            PreparedStatement ps=con.prepareStatement("insert into emp values(?,?,?)");
            ps.setString(1,name);
            ps.setString(2,branch);
            ps.setInt(3,regd);
            int k=ps.executeUpdate();
            if(k>0)
                b=true;
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
        return b;
    }
}

InsertForm.java

package com.cac.struts;
import org.apache.struts.action.ActionForm;
public class InsertForm extends ActionForm
{
    private int regd;
    private String name;
    private String branch;
    public void setRegd(int r)
    {
        regd=r;
    }
    public int getRegd()
    {
        return regd;
    }
    public void setName(String name)
    {
        this.name=name;
    }
    public String getName()
    {
        return name;
    }
    public void setBranch(String branch)
    {
        this.branch=branch;
    }
    public String getBranch()
    {
        return branch;
    }
}

InsertAction.java

package com.cac.struts;
import org.apache.struts.action.*;
import javax.servlet.http.*;
public class InsertAction extends Action
{
    public ActionForward execute(ActionMapping am,ActionForm af,HttpServletRequest hreq,HttpServletResponse hres) throws Exception
    {
        String key="failure";
        InsertForm iif=(InsertForm)af;
        int regd=iif.getRegd();
        String name=iif.getName();
        String branch=iif.getBranch();
        InsertModel im=new InsertModel();
        boolean b=im.insert(name,branch,regd);
        if(b)
        {
            key="success";
        }
        ActionForward af1=am.findForward(key);
        return af1;
    }
}

insert.jsp

<％@ taglib uri = "/ WEB-INF / struts-html.tld" prefix = "html"％>

<html:html>
    <body bgcolor="yellow">

あなたはおそらくこれらの瓶の1つを逃しています：

commons
-digester.jar commons-beanutils.jar
struts.jar

それらをプロジェクトに追加すると、問題が解決するはずです
