Cloud DB Java Server SDK Demo does not compile about agc-demos

[Mayism]

@alterEgo123 The dependency related to the error exists in the demo and has been imported to the app.java file (for example, the BookInfo class exists in the directory of .\src\main\java\com\huawei\agc\clouddb\quickstart\model).Check whether the compiled demo project is consistent with that in the repo file and try again.for more guides,please refer to documents.

@Mayism Even the JavaScript demo doesn't work. It returns this error

I have changed my credentials file and created the Cloud DB Zone as mentioned in the tutorial.

@alterEgo123 the property of 'executeQuery' depends on the javascript server sdk of clouddb. maybe you should integrate it firstly to solve the error.

[alterEgo123]

'undefined' refers to cloudDBZoneClient in CloudDBZoneWrapper which is not being initialized, even though I've set credentialPath and zoneName

Hello, @alterEgo123 can you please provide the full stack trace of the java error. I shall take a look at this for you, lets focus on the java error first. If you do want to look into the javascript as well let's keep it on a separate ticket to avoid confusion.

Thank you!
