writing spring RESTful end point using java 1.4 - spring

Is there any way to develop spring based restful end point using jdk1.4(non annotation base approach because java 1.4 won't support) ?
I have oc4j server(oracle application server) version 10.1.3 which supports j2sdk 1.4 and servlet 2.4. I believe I won't be able to deploy a springboot restful web service in my oc4j server because of jdk1.4(minimum java version required for springboot is 1.6)

Yes I agree Spring Boot is not possible for my scenario. I am asking if it is possible to develop spring web-mvc using jdk 1.4 and servlet 2.4 version ?

You may need to use the XML based configurations for initializing spring context. A RESTful application can be built even without using Spring using Jersey or some other JAX-RS implementations, if you are not going to use any Spring capabilities.

Is spring-data-rest-webmvc:3.4.x compatible with Spring Boot 2.3.x?

There is a vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2021-22047) discovered in spring-data-rest-webmvc which is only fixed in versions 3.4.14 and 3.5.6. Spring Boot 2.3.12 uses the version 3.3.9. Migrating to spring boot 2.4.x or above is not an option for us.
We would like to use spring-data-rest-webmvc:3.4.14, but we are not sure if it's compatible with spring boot 2.3.x.
Can we use them together?
Spring Data Rest version 3.4 and up use Spring Framework version 5.3.x.
Spring Boot 2.3 is build with Spring Framework 5.2.x.
Will it work, probably, but there are no garanties that it will keep working or work at all. Most like it will fail with some NoSuchMethodError or ClassNotFOundExceptions or other exotic expetions one gets when mixing modules/jars from different versions of a framework.

Use of Spring 5.3 with Servlet 3.0

I'm working on application which uses Spring Core in version 4.3.14 and Spring Web in version 4.2.13. We don't use Spring MVC. Also, from Spring Web we use just very limited set of classes:
XmlWebApplicationContext (so classes from org.springframework.web.context)
RestTemplate (so classes from org.springframework.web.client, here i expect some problems)
some util classes which probably can be refactored to use something else
My question is:
We want to migrate to Spring 5.x. Is such a migration really possible? Or should i expect some severe problems with application startup (class incompatibilites etc). This source for example: https://github.com/spring-projects/spring-framework/wiki/What%27s-New-in-Spring-Framework-5.x#whats-new-in-version-50 says that Servlet 3.1 is required
From the other side, here https://spring.io/blog/2015/06/10/feedback-welcome-spring-5-system-requirements JUERGEN HOELLER wrote that migration to Spring 5 will be a soft one. So i assume that if Application uses only features from JEE6 + Servlet 3.0, then it can be that it will also work on Spring 5.x with JEE6-compatible appserver
Does anyone have an experience in that?
As always, Spring Framework upgrades its baseline with new major versions. In this case, we're requiring JDK8+ and Java EE7+.
In practice, this means that the compiled code depends on those APIs and doesn't use reflection anymore to adapt to them. In your case, this is not only about Servlet, but also JPA, JMS, bean validation and other specs.
Your application might work fine with the arrangement you're mentioning, but the Spring team will not guarantee support for this setup.

Spring-Boot 1.5.10.release compatibility with apache-kafka-2.3.0 client

My project is built with Spring boot 1.5.10.release. We want to migrate to Apache Kafka® 2.3.0 from Apache Kafka 1.0.x.
We are currently using Spring-kafka 1.3.9.release and want to migrate to spring-kafka-2.3.0. Can we do this without changing the Spring boot version of 1.5.10.release?
I went through the Compatibility matrix but I don't see any relevant answer to my question
https://spring.io/projects/spring-kafka
No, you can't do that. Spring Kafka 2.x, as well Spring Boot 2.x, is based on Spring Framework 5.x and Java 8. You can't mix so critical versions in Spring Boot 1.5.x.
It is really better to rely on the Spring Boot dependencies management. That way you can be sure that all the artifacts brought by Spring Boot are tested together.

Can I use "Spring Data JDBC" with Spring Boot 1.5.x?

I have tried to figure out which version of spring-data-jdbc to use with Spring Boot 1.5.20.RELEASE (= Spring Framework 4.3.23.RELEASE) - but I can't find that info anywhere.
Is it because spring-data-jdbc only work with Spring Boot 2.x / Spring Framework 5.x?
Specifically I want to use #Query, #EnableJdbcRepositories, etc.
When I look at the release notes for Spring Data Ingalls SR20 (the release train that matches Boot 1.5.20.RELEASE / Framework 4.3.23.RELEASE) it looks like spring-data-jdbc is only supported in Lovelace (Boot 2.x and Framework 5.x): https://spring.io/blog/2019/04/10/spring-data-lovelace-sr6-kay-sr14-ingalls-sr20-released
EDIT & ANSWER: As per comment from #JensSchauder: spring-data-jdbc is a (fairly) new project created from scratch. There is no way to use it with Spring Framework 4.
If you look at the spring-data-jdbc pom.xml it uses spring-data-parent to manage Spring Framework version by defining and applying spring.version property. You must ensure that this Spring Framework version is compatible with whatever version you are using.
The first available spring-data-jdbc:1.0.0.RELEASE version uses spring-data-parent:2.1.0.RELEASE parent which requires Spring Framework 5.1:
<spring>5.1.0.RELEASE</spring>
It's not be recommended to use spring-data-jdbc with lower Spring Framework version. Since Spring Boot 1.5.X uses Spring Framework 4.X the answer would be no.

Spring mvc compatibile with Servlet 2.5

I have developed some rest services with Spring mvc 3.0.9. In some case I have an exception. It depends that my spring version use Servlet 3.0 api (my application server is jboss eap 5.1). What is latest spring mvc version compatible with Servlet 2.5? Thanks.
Spring 3.2 should work with Servlet 2.5 API.
Only Spring 4.0 requires Serlvet 3.0:
refer this official documentation for more info.
3 New Features and Enhancements in Spring Framework 4.0)
3.4 Java EE 6 and 7
Java EE version 6 or above is now considered the baseline for Spring
Framework 4, with the JPA 2.0 and Servlet 3.0 specifications being of
particular relevance.
Spring 4.0 work with Servlet 2.5.
See document: (https://docs.spring.io/spring/docs/4.3.14.RELEASE/spring-framework-reference/htmlsingle/)
3.4 Java EE 6 and 7
Java EE version 6 or above is now considered the baseline for Spring
Framework 4, with the JPA 2.0 and Servlet 3.0 specifications being of
particular relevance. In order to remain compatible with Google App
Engine and older application servers, it is possible to deploy a
Spring 4 application into a Servlet 2.5 environment. However, Servlet
3.0+ is strongly recommended and a prerequisite in Spring’s test and mock packages for test setups in development environments.
3.7 General Web Improvements
Deployment to Servlet 2.5 servers remains an option, but Spring
Framework 4.0 is now focused primarily on Servlet 3.0+ environments.
If you are using the Spring MVC Test Framework you will need to ensure
that a Servlet 3.0 compatible JAR is in your test classpath.
