[enterprise-4.7] Issue in file cli_reference/developer_cli_odo/creating_and_deploying_applications_with_odo/creating-a-java-application-with-a-database.adoc

[Keyvan-rh]

Which section(s) is the issue in?

CLI tools / Creating a Java application with a database
Creating a Java MicroServices JPA application
Clone the sample application:

What needs fixing?

First issue:
The following git clone will not work as the application is not at the master level
git clone https://github.com/redhat-developer/application-stack-samples
you need to clone the correct branch
git clone -b jpa-sample https://github.com/redhat-developer/application-stack-samples.git

Second issue:
the following command did not show the same output as documentation
odo exec -- bash -c 'export | grep DATABASE'
but using the "env" would show the result:
odo exec -- bash -c 'env | grep DATABASE'
