I'm trying to integrate SQL Server 2016 and H2 in-memory database for one of my Spring Boot project. All the configuration is set and I'm able to load persistence-unit for both database without any problem. Also, I can query for SQL Server Database and I'm getting my data too. Sql Server JPA configuration is my primary configuration. But, somehow JPA is not able to create entity in H2 database. And after seeing log, I came into the conclusion that the entity that I'm trying to create in H2 is actually trying to find that in SqlServer Datbase. Some part of log for this complain is below:
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Invalid object name 'person'.

I don’t know why it is trying to look for Person object in SQL Server. Do anyone have some idea on this. I'm looking after this issue for last 24 hrs. But, didn't find anything. Person table should be created in H2 database. Everything is fine SQL Server side.
I don't know if this will solve your problem but :
This is not the way JPA is supposed to work. Instead create a new Person() object, which should be an #Entity, and set its attributes, then entityManager.persist(person).
I am getting the NullPointerException after executing the below testng test script. After launching the URL when it comes inside the test script method then, it is throwing the exception. Can you please help me out in this.

This instantiation is illegal.
LakesAndMountainsHomePage lm = new LakesAndMountainsHomePage(this.driver);
It is the root cause of Null pointer exception.
Move this statement to BaseTest class, create a class field and instantiate inside #BeforeClass method . Also, remove this operator.
Well i'am unable to see the implementation of a driver class specifying the type of driver(firefox,chrome,IE) being initialized.
I am trying to automate and have integrated Selenium with Appium and I am using Eclipse with TestNG for execution.
Now within a project I have a package with two classes; the first class is for login into the App and the second class is for logout
First class code -

try {

<class name = "com.gma.test.Logout"/>
</classes>
</test>
</suite>
I receive Null Pointer exception after execution of first class. Appium server stops saying no more commands received. Please help.
You are getting NPE b'coz you have declared one more driver reference public AppiumDriver driver; in your Logout class.
And you are using this driver reference without instantiation.
In logout class you forget to instantiate your AppiumDriver driver.
try this:
public AppiumDriver driver;
driver = new AndroidDriver();
I want to display content of an Oracle Database in my TableView "FilmTable".
The structure of the Oracle Databade is: a table column named "FILMTITEL" in the table "LUKA1". The are 4 Film names like Fast and Furious, ...

Make sure you use -libjars in commands. like the following :
bin/hadoop jar wordcount.jar org.myorg.DBCountPageView -libjars mysql-connector-java-5.1.26-bin.jar
Please reference http://hadoop.apache.org/docs/r1.2.1/mapred_tutorial.html's usage part
Not sure what the scope of your app is (learning, dev, etc.) but I would suggest to use Sqoop to interact with a relational database such as MySQL.
