做个记号！等下再来仔细看

[myyucat]

你是在运行mastering EJB吧！
你的bean中的getproductID的方法名写成了getproductid。

做个记号！等下再来仔细看

我强烈建议用工具生成，这样写，又麻烦又容易错！

我的ProductBean.java如下
感觉没问题啊



package examples;


import javax.ejb.*;


public abstract class ProductBean implements EntityBean {
protected EntityContext ctx;

public ProductBean() {}

public abstract String getName();

public abstract void setName(String name);

public abstract String getDescription();

public abstract void setDescription(String description);

public abstract String getProductID();

public abstract void setProductID(String productID);

public abstract double getBasePrice();

public abstract void setBasePrice(double basePrice);


public void ejbActivate() {
System.out.println("ejbActivate() called.");
}

public void ejbRemove() {
System.out.println("ejbRemove() called.");
}

public void ejbPassivate() {
System.out.println("ejbPassivate() called.");
}

public void ejbLoad() {
System.out.println("ejbLoad() called.");
}

public void ejbStore() {
System.out.println("ejbStore() called.");
}

public void setEntityContext(EntityContext ctx) {
System.out.println("setEntityContext called");
this.ctx = ctx;
}

public void unsetEntityContext() {
System.out.println("unsetEntityContext called");
this.ctx = null;
}

public void ejbPostCreate(String productID, String name, String description, double basePrice) {
System.out.println("ejbPostCreate() called");
}

public ProductPK ejbCreate(String productID, String name, String description, double basePrice)
throws CreateException {
System.out.println("ejbCreate() called");

setProductID(productID);
setName(name);
setDescription(description);
setBasePrice(basePrice);

return new ProductPK(productID);
}
}
