java - Send notification to the client from a web server -

-

In my setup, there is a weblogic server that runs various restore services that accepts an HTTP request from the customer (an Android app), reads data from a MySQL database, and this data as a client's response Sends.

My requirement is that as soon as the database is updated, the customer should be informed. I have applied a "voting" mechanism, constantly sending requests and inquiries for any changes made to the customer database. Although this is not a very efficient mechanism, can you please suggest any effective way of getting it?

Thanks in advance!

One way to write a cron job for an overview of database changes.

Also, so this topic has already been discussed. Refer to the link given below,

Selenium IDE Conditional Statements -

I want to ask if there is another way to see the error label, which has been shown whether we There is no need to fill up with the necessary to use the verifyText command. Here's an example: id: [required] PW: [required] Email: [expected] Dropdown box: [required] If you make test cases, then there is an easy way to make a test case first, and then three error labels will show whether the other fields will not be filled with that.

Before saving that field, I'm just using the verified text, but if there are many conditional requirements like this there is no easy and easy way to create this testcase?
