WCS学习笔记(第九天) - MyNewControllerCmd整合Bonus entity bean

1. 修改BonusDataBean.java实现：

a. 参数userId、totalBonusPoints的get、set方法

/// Section 1 ///////////////////////////////////////////////

// create fields and accessors (setter/getter methods)

private java.lang.String userId;
private java.lang.Integer totalBonusPoints;

public java.lang.String getUserId() {
return userId;
}

public void setUserId(java.lang.String newUserId) {
userId = newUserId;

///////////////////////////////////////
/// Section A : instantiate BonusAccessbean

if (userId != null)
this.setInitKey_memberId(new Long(newUserId));

///////////////////////////////////////
}

public java.lang.Integer getTotalBonusPoints() {
return totalBonusPoints;
}
public void setTotalBonusPoints(java.lang.Integer newTotalBonusPoints) {
totalBonusPoints= newTotalBonusPoints;
}

//// End of section 1 ////////////////////////////////////////////

b. 创建BonusDataBean(BonusAccessBean bb)方法：

/// Section 2///////////////////////////////////////////////

// create a new constructor for passing access bean into databean
// so that JSP can work with the access bean

public BonusDataBean(BonusAccessBean bb)
throws com.ibm.commerce.exception.ECException {
try {
super.setEJBRef(bb.getEJBRef());
}  catch (javax.ejb.FinderException e) {
throw new ECSystemException(ECMessage._ERR_CREATE_EXCEPTION,
"BonusDataBean", "BonusDataBean(bb)");
} catch (javax.naming.NamingException e) {
throw new ECSystemException(ECMessage._ERR_NAMING_EXCEPTION,
"BonusDataBean", "BonusDataBean(bb)");
} catch (java.rmi.RemoteException e) {
throw new ECSystemException(ECMessage._ERR_REMOTE_EXCEPTION,
"BonusDataBean", "BonusDataBean(bb)");
} catch (javax.ejb.CreateException e) {
throw new ECSystemException(ECMessage._ERR_CREATE_EXCEPTION,
"BonusDataBean", "BonusDataBean(bb)");
}
}

//// End of section 2 ////////////////////////////////////////////

c. 具体实现populate()方法体

//// Section 3 /////////////////////////////////////////////////

// set additional data field that is used for instantiating BonusAccessbean

try
{

setUserId(getRequestProperties().getString("taskOutputUserId"));

try {
super.refreshCopyHelper();
} catch (javax.ejb.FinderException e) {
throw new ECSystemException(ECMessage._ERR_CREATE_EXCEPTION,
"BonusDataBean", "populate");
} catch (javax.naming.NamingException e) {
throw new ECSystemException(ECMessage._ERR_NAMING_EXCEPTION,
"BonusDataBean", "populate");
} catch (java.rmi.RemoteException e) {
throw new ECSystemException(ECMessage._ERR_REMOTE_EXCEPTION,
"BonusDataBean", "populate");
} catch (javax.ejb.CreateException e) {
throw new ECSystemException(ECMessage._ERR_CREATE_EXCEPTION,
"BonusDataBean", "populate");
}

}
catch (ParameterNotFoundException e){}

///// End of Section 3 /////////////////////////////////////////
}

d. 具体实现setRequestProperties(com.ibm.commerce.datatype.TypedProperty aParam)
方法体

/// Section 4 ///////////////////////////////////////////

// copy input TypedProperties to local

requestProperties = aParam;

/// End of section 4 ////////////////////////////////////

5. 确认商店(如：Madisons)的对应会员ID：

a. 启动wcs服务器；

b. IE打开：URL: http://localhost/webapp/wcs/admin/servlet/db.jsp;

c. 查询sql:

select member_id from storeent where storeent_id=10051;

6. 注册页面：

a. 停止server

b. 编写SampleACPolicy.xml 和 SampleACPolicy_en_US.xml 放在
WCDE_installdir\xml\policies\xml (ConsumerDirectMemberId替换为sql查询的-2003)

SampleACPolicy.xml

<?xml version="1.0" encoding="ISO-8859-1" standalone="no" ?>
<!DOCTYPE Policies SYSTEM "../dtd/accesscontrolpolicies.dtd">

<PolicyGroupPolicy 	Name="AllUsersExecuteMyNewControllerCmdOnUserResource" PolicyOwnerID="-2003" />

</PolicyGroup>

</Policies>

SampleACPolicy_en_US.xml

<?xml version="1.0" encoding="ISO-8859-1" standalone="no" ?>
<!DOCTYPE PoliciesNLS SYSTEM "../dtd/accesscontrolpoliciesnls.dtd">

</PoliciesNLS>

c. 命令定位到WCDE_installdir\bin
(如：cd C:\IBM\WCDE_PRO70\bin)，执行下面命令





7. 修改JSP页面：

a. 在MyNewJSPTemplate.jsp的SECTION 9中增加下面代码，用于显示bean传递和更新的信息：

<!-- SECTION 9 -->

<h2><fmt:message key="BonusAdmin" bundle="${tutorial}" /> </h2>

<c:if test="${!empty taskOutputUserId}">
<ul>
<li>
<b>
<fmt:message key="PointBeforeUpdate" bundle="${tutorial}" />
<c:out value="${oldBonusPoints}"/>
</b>
</li>
<li>
<b>
<fmt:message key="PointAfterUpdate" bundle="${tutorial}" />
<c:out value="${bdbInstance.bonusPoint}" />
</b>
</li>
</ul>
</c:if>

<br />
<b><fmt:message key="EnterPoint" bundle="${tutorial}" /></b><p />

<form name="Bonus" action="MyNewControllerCmd">
<table>
<tr>
<td>
<b>Logon ID </b>
</td>
<td>
<input type="text" name="input1" value="<c:out
value="${userName}"/>" />
</td>
</tr>
<tr>
<td>
<b>Bonus Point</b>
</td>
<td>
<input type="text" name="input2" />
</td>
</tr>
<tr>
<td colspan="2">
<input type="submit" />
</td>
</tr>
</table>
</form>

<!-- END OF SECTION 9 -->

8. 测试：

a. 启动server

b. 登陆前台用户

c. 访问: http://localhost/webapp/wcs/stores/servlet/MyNewControllerCmd?input1=logon_id&input2=2000 (注：由于缓存可在url后加如:
?StoreId=10051 )
