如何assert在Eclipse中启用关键字？

public class A
{
    public static void main(String ... args)
    {
        System.out.println(1);
        assert false;
        System.out.println(2);
    }
}

我的tomcat服务器在Eclipse中工作正常,但是当我尝试启动服务器时它没有启动.

以下是错误:

这个问题与oracle 10g数据库有关.相同的代码与MySQL数据库一起工作正常.

我的模型类

package com.killerlinks.model;

    import java.io.Serializable;
    import java.sql.Blob;

    import javax.persistence.Column;
    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.GenerationType;
    import javax.persistence.Id;
    import javax.persistence.Lob;
    import javax.persistence.Table;

    @Entity
    @Table(name="links")
    public class Linkform implements Serializable
    {
        /**

        private static final long serialVersionUID = 1L;

这是我用来通过FTP使用Jakarta Commons Net将文件上传到远程位置的代码

public boolean ftpTransfer(String localfile, String destinationfile)
        {
            String server = "xxxx";
            String username = "xxxxxx";
            String password = "xxxxxxx";
            try
            {
                FTPClient ftp = new FTPClient();
                ftp.connect(server);
                if(!ftp.login(username, password))
                {
                    System.out.println("login");
                    ftp.logout();
                    return false;
                }
                int reply = ftp.getReplyCode();
                if (!FTPReply.isPositiveCompletion(reply))
                {
                    System.out.println("disconnect");
                    ftp.disconnect();
                    return false;
                }
                InputStream in = new FileInputStream(localfile);
                ftp.storeFile(destinationfile, in);
                in.close();
                ftp.logout();
                ftp.disconnect();
            }
            catch (Exception ex)
            {
                ex.printStackTrace();
                return false;
            }
            return true;
        }
