我正在开发基于jQuery的移动应用程序并尝试使用我的自定义登录页面进行单步验证。登录页面从用户收集贷款＃和pin并使用它们查询MS SQL Server数据库，如下所示。
我创建了SQL适配器来访问MS SQL Server数据库，当我选择适配器时，它可以从工作区成功运行 - ＆gt;运行方式 - ＆gt;调用适配器过程。但它不能从我的challaengerHandler.js起作用并抛出异常。我已经将sqljdbc4.jar文件存储到项目的server / lib文件夹中。
以下是adapter.xml
的内容<displayName>LoanInfoMSSQLAdapter</displayName>
<description>LoanInfoMSSQLAdapter</description>
<connectivity>
<connectionPolicy xsi:type="sql:SQLConnectionPolicy">
<!-- Example for using a JNDI data source, replace with actual data source name -->
<!-- <dataSourceJNDIName>java:/data-source-jndi-name</dataSourceJNDIName> -->
<!-- Example for using MySQL connector, do not forget to put the MySQL connector library in the project's lib folder -->
<dataSourceDefinition>

<password>lbps</password>
</dataSourceDefinition>
</connectionPolicy>
<loadConstraints maxConcurrentConnectionsPerNode="5" />
</connectivity>
<!-- Replace this with appropriate procedures -->
<procedure name="getLoanInfoFromDB"/>
以下是来自adapter-impl.js
的内容var getLoanInfoStatement = WL.Server.createSQLStatement(
"SELECT account_id, pin, borr_ssn " +
"FROM vw_wcc_cust " +
"WHERE vw_wcc_cust.account_id = ? AND pin = ?;"
);
function getLoanInfoFromDB(loan, pin) {
return WL.Server.invokeSQLStatement({
preparedStatement : getLoanInfoStatement,
parameters : [loan, pin]
});
}
以下是Challangerhandler.js的内容
$("#AuthSubmitButton").bind('click', function () {
WL.Logger.debug("SUBMIT button clicked...");
var loan = $("#AuthLoan").val();
var pin = $("#AuthPin").val();
WL.Logger.debug("AuthLoan = " + loan);
WL.Logger.debug("AuthPin = " + pin);
WL.Logger.debug("Invoking WL.Client.connect() function to check for connectivity...");
var connectOptions = {
onSuccess : function() {
WL.Logger.debug("Device is connected to WL server");
var invocationData = {
adapter : "SetSnapshotAuthAdapter",
procedure : "submitAuthentication",
parameters : [ loan, pin ]
};
SetSnapshotAuthRealmChallengeHandler.submitAdapterAuthentication(invocationData, {});
},
onFailure: function() {
WL.Logger.debug("Device is NOT connected to WL server");
alert("Worklight Server Unavailable. Try your request later-001");
}
};
WL.Client.connect(connectOptions);
});
以下是SIngle Step Authentication Adapeter的js文件的submitAuthentication（）函数的内容
function submitAuthentication(loan, pin){
WL.Logger.info("Inside submitAuthentication");
WL.Logger.info("Loan = " + loan);
WL.Logger.info("Pin = " + pin);
var loanInfos = WL.Server.invokeSQLStatement({
preparedStatement : getLoanInfoStatement,
parameters : [loan, pin]
});
var username = "seterus";
// if（username ===“seterus”＆amp;＆amp; password ===“seterus”）{
if (loanInfos) {
var userIdentity = {
userId: username,
displayName: username,
attributes: {
foo: "bar",
loan: loan,
pin: pin,
isSuccessful: loanInfos.isSuccessful
}
};
WL.Logger.info("Loan from userIdentity = " + userIdentity.attributes.loan);
WL.Logger.info("Pin from userIdentity = " + userIdentity.attributes.pin);
WL.Server.setActiveUser("SetSnapshotAuthRealm", userIdentity);
WL.Logger.info("Returning authRequired as FALSE to display loan info...");
return {
authRequired: false
};
}
return onAuthRequired(null, "Invalid login credentials");
}
输入贷款＃和pin然后点击提交按钮后，我在eclipse控制台视图中收到以下异常：

我尝试按照SQL Adapter示例以及单步身份验证适配器示例进行操作。该代码适用于单步授权适配器和硬编码数据，但只要我尝试将SQL适配器包含在硬编码数据中，它就会给我这个问题。
有一些帖子有同样的问题，我试图按照那里的代码实现这一点，但我仍然没有得到理想的结果。
如果您还需要更多信息，请与我们联系。如果代码片段在发布时效果不好，请原谅我，因为我是Stack Overflow网站的新手。
谢谢， SHAILESH
答案 0 :(得分：0)
我成功连接到数据库并在测试应用程序中执行查询。我使用了Worklight InfoCenter的“高级适配器使用和mashup”部分的示例练习。我在我的实际应用程序中使用了相同的样式，并且我成功地从Microsft SQL Server检索记录。谢谢你的建议。 - Shailesh
