我正在尝试将JSONStore用于其中一个要求。
由于它是混合应用程序，我通过以下配置 程序
使用应用程序描述符编辑器打开文件 application-descriptor.xml单击“设计”选项卡。在概述下， 展开应用程序[您的应用程序名称]。单击可选 特征。单击添加。选择JSONStore。单击确定。在项目中 在资源管理器视图中，右键单击标有您的文件夹 应用名称。单击运行方式。单击“在MobileFirst Development上运行” 服务器
以下是我用于在JSONStore中创建文档的示例代码。我按照documentation中的说明进行了操作。
WL.Logger.debug ("Successfully connected to MobileFirst Server.");
var collectionName = 'SomeFlag';
if(WL.JSONStore.get(collectionName) == null && WL.JSONStore.get(collectionName) == undefined){
// Object that defines all the collections.
var collections = {
// Object that defines the 'people' collection.
userAgreement : {
// Object that defines the Search Fields for the 'people' collection.
searchFields : {someFlag: 'boolean'}
}
};
// Optional options object.
var options = {
localKeyGen : false
};
WL.JSONStore.init(collections, options)
.then(function () {
var data = [{someFlag: false}];
// Optional options for add.
var addOptions = {
// Mark data as dirty (true = yes, false = no), default true.
markDirty: true
};
// Get an accessor to the people collection and add data.
return WL.JSONStore.get(collectionName).add(data, addOptions);
})
.then(function (numberOfDocumentsAdded) {
WL.Logger.debug ("Number Of Documents Added " +numberOfDocumentsAdded);
alert ("Number Of Documents Added " +numberOfDocumentsAdded);
// Add was successful.
})
.fail(function (errorObject) {
// Handle failure for any of the previous JSONStore operations (init, add).
WL.Logger.debug ("JSONStore Failed to add any document errorObject " +errorObject);
});
}
在Android中运行时，JSONStore创建失败。

我正在使用与评论中提到的相同的构建，并且能够成功运行JSONStore，而不会遇到此错误。
共同添加以下代码/ js / main.js＆gt; wlCommonInit()：
function wlCommonInit(){
var collectionName = 'people';
// Object that defines all the collections.
var collections = {
// Object that defines the 'people' collection.
people : {
// Object that defines the Search Fields for the 'people' collection.
searchFields : {name: 'string', age: 'integer'}
}
};
// Optional options object.
var options = {
// Optional username, default 'jsonstore'.
username : 'carlos',
// Optional password, default no password.
password : '123',
// Optional local key generation flag, default false.
localKeyGen : false
};
WL.JSONStore.init(collections, options)
.then(function () {
alert ("success");
});
}
我在Android模拟器中启动了应用程序并显示了警告。

终于搞定了。我发现jsonstore.jar没有包含在我的Android项目库中，这导致了这个错误。
