QUESTION
I am trying to create a Spring MVC web application that checks the current weather by calling an external API from "https://api.weather.gov/points/{latitude},{longitude}". The latitude and longitude needs to be an user input which you take from an html form, pass it onto your controller and then use that latitude and longitude while you make the external call. The json from the api call contains grid points which again is necessary to make another external API call "https://api.weather.gov/gridpoints/{gridX},{gridY}/forecast" and then extract results and show it on the front end.
My html form looks something like this.(homepage.html)
...ANSWER
Answered 2022-Feb-20 at 17:41The weather API return an json object as the result. You are telling spring to convert it into an array of Objects. The error points out that you cannot do so as it is expecting the json response to be an array of json objects .

QUESTION
I have been trying to understand and clone the spring mvc login and registration process. As far as I know I am following the same code and process. Only thing I have changed is database details.0 Which works fine I am able to insert the data into the MySQL (8.0.27) database using test file. I am getting the same error even when I am trying his code I am getting error.
here is my code: https://drive.google.com/drive/folders/1JNkZp_O1Lh0y_1NdZ-A85KI1gfgy0_Em?usp=sharing
here is GitHub code: https://github.com/javabyranjith/spring-framework-mvc/tree/master/springmvc-userlogin
Errors I am getting:
- action keyword in form was giving error "element loginProcess is not found"-> so I changed it to the form action then it worked
- The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
my questions are
- can a different version of Apache Tomcat(10.0.13) server can cause the issue?
- since I am using new Eclipse so I have updated the new libraries can this cause the issues?
Please suggest the changes so that I can run this project. Suggest the changes here or directly change it in the google drive folder.
...ANSWER
Answered 2022-Jan-09 at 11:31Tomcat 10 does not work with Spring 5. Downgrade to Tomcat 9. 10th has jakarta packages renamed from javax, which spring 5 does not support.
Friendly advice, if you are using code from git, they left versions of stuff like java and tomcat for a reason, and the newest versions like Tomcat 10 and JDK17 went through a lot of changes, so always try with suggested versions and try to migrate them to higher ones. Except for Tomcat 10, you will have to wait for Spring 6 for that.
As for the new eclipse, it does not make any difference, the maven project is still the maven project, src, and pom.xml, the structure remained the same.
First try with suggested versions then you can ramp them up once you are sure that it is working.

QUESTION
My application is using the following:
JDK version: Open JDK
jdk-11.0.11+9
Payara : 5.2021.5
Spring version: 5.2.7.RELEASE
jackson version: 2.9.4.
Payara 5.2021.5 uses Jackson version 2.10.2, whereas the application uses Jackson version: 2.9.4. It looks like the method signature for some Jackson methods used by SpringMVC has changed in Jackson 2.10.2.
On Server startup, the following Exception is thrown:
ANSWER
Answered 2021-Jul-28 at 21:12tried disabling class loading hierarchy locally by setting element in the glassfish-web.xml. It looks like Payara ignores this flag and continues to load the libraries in \payara-5.2021.5\payara5\glassfish\modules, instead of loading from the application. I even tried by replacing glassfish-web.xml with payara-web.xml
The issue resolved by setting system property fish.payara.classloading.delegate to false in domain.xml.

Install springmvc
You can use springmvc like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the springmvc component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
