kandi X-RAY | javaee-spec Summary
This is the project for the Java EE Platform specification. The Java EE Platform specification is the umbrella specification that defines the Java EE platform. The platform specification doesn't define the Java EE APIs directly, but rather includes them by reference to other Java specifications and defines how they all fit together in the overall Java EE platform. The platform specification also defines other attributes of the platform such as security, deployment, transactions, and interoperability.

I am trying to figure out syntax for
Column annotation when i want to add
So far what i have tried:...

Javax Validation APIs might help. Based on annotations and a validator, you can apply and check column-level constraints.
I'm using javax.validation.constraints and have already checked the package usage but still can't find what I'd like to do. https://javaee.github.io/javaee-spec/javadocs/javax/validation/constraints/package-summary.html
Here are the two of the variables being sent from the request body...

what you are looking for is using Cross-Parameter Constraints. some basic guide can be found here chapter 2.x https://www.baeldung.com/javax-validation-method-constraints
Today, I discovered that it is possible to autowire
HttpServletRequest into arbitrary singleton Spring beans.
ANSWERAnswered 2020-Dec-02 at 08:56
That possibility of autowiring the proxy for
HttpServletRequest's is a part of Spring MVC, and sadly it's not documented properly.
The best you can find about it is in some release notes of
spring-web:3.0.0. For example, take a look at the release notes of 3.0.0.M4 and especially at this issue where Juergen Hoeller (one of the main developers of String) talks about how it works since this version.
I have the following very simple design:
A club has multiple teams, and each team having a team type code (a gender - age group code) plus an ordinal (team) number, e.g. MALE OVER 20 would be "MO20", with the ordinal number representing the 1st, 2nd etc. team for that age group. This is the PK for the
Teams. You get the point.

@MapsId("clubId") on the association, you're saying '
clubId does not provide its own mapping. Instead, the mapping on this property here should be used to map the
This means that when persisting the entity, Eclipselink will use
Team.club's id to populate the
club_id join column, and then, it will use the value of that join column, to populate the Java property
Team.embeddedId.clubId, whenever the entity is fetched/refreshed. Whatever mapping you put on
Team.embeddedId.clubId will be ignored.
The error comes from the fact that Eclipselink does not consider
club_id to be mapped twice. Instead, only the mapping on
Team.club is taken into account. Being the only mapping for a primary key property, it may not be
insertable = false, updatable = false.
The solution is simple:
- If you want
Team.clubto control the value of the
club_idcolumn, drop the
insertable = false, updatable = false
- Conversely, if you want

Sometime required parameter is not there so it gives an error. In your question not whole code or error snep is given so i describe on my way.
Check following two points first,
- All required configuration data are provided.
- Your email id must have permission to send mail using your application (Allow "less secure app" in your gmail account - if you're using).
I am on the java tomcat stack and creating a new filter. https://javaee.github.io/javaee-spec/javadocs/javax/servlet/http/HttpFilter.html I am interested in unit testing it because I want to have 100% branch coverage.
This filter wraps the response object. We override the default behavior of the response such that whenever we call response.addCookie(cookie), we append the string "happy" to the cookie name:...

"What would be the benefit of testing
Quoting answer to the question "Should unit tests be written for getter and setters?":
Unit tests are there to test the behaviour of your code, ...
There is really no behavior to be tested in that
Filter code. The behavior to be tested is in the
HappyCookieResponseWrapper class, and you're already testing that. Repeating that test would just be a waste of time.
"I want to have 100% branch coverage"
Quoting a different part of the same answer above:
@Will said you should aim for 100% code coverage, but in my opinion that's a dangerous distraction. You can write unit tests that have 100% coverage, and yet test absolutely nothing.
