java - 在 Bean 类方法中调用 Generic 类会出现错误

Question

我正在尝试编译 serviceBean.java 文件，该文件导入我的包之一，ledgement.java

在 serviceBean.java 中，我添加了以下一行，但未编译它会抛出 Cannot Find Symbol

ledgement ack = new ledgement(false,
                        e);

Here is the folder structure:

C:\working\src\java\com\test\tools\abc\mgmt\facade\service    

com/test/tools/abc/mgmt/facade/service/serviceBean.java

com/test/tools/abc/mgmt/util/ledgement.java

我的分类包含

 public class ledgement<T> extends Test {

        public enum EntityType implements Serializable {
            ART(1), ART1(2), RDER(3), LNE(4), 
            COUNT(5);
            private int typeId;

            EntityType(int id) {
                this.typeId = id;
            }

            /**
             * @return the entityClass
             */
            public int getTypeId() {
                return typeId;
            }

            /**
             * @param entityClass
             *            the entityClass to set
             */
            public void setTypeId(int id) {
                this.typeId = id;
            }
        } // Enum EntityType.

    public ledgement(boolean successFg) {
            this(successFg , null, null, null, null);
        }
   public ledgement(boolean sucessFg, Exception exp) {
        this(sucessFg, exp, null);
    }

它抛出找不到符号 [javac] 符号:构造函数台词( boolean 值，java.lang.Exception)

Not sure what is the issue by invoke the ledgment java class.
Please help.Thanks in Advance

这行代码中有一个额外的括号:this(successFg) , null, null, null, null);
