Is there a version of Solrj built for the JDK 1.4?
I installed the latest release of Solr on a separate Tomcat instance, but I have to send requests via an application developed (and deployed) with JDK 1.4
The archive at http://www.us.apache.org/dist/lucene/solr/
seems to contain only versions compliant with JDK5 or later

Few years back, I develop a web application using Java 1.7, SpringFramework 4.1.1.RELEASE and Hibernate 3.6.10.Final. This webapp is running on Tomcat 7.0.4 at the time.
Now, I planning to upgrade and compile everything using OpenJDK 19, and Tomcat 10.1.
How do I know which version to use in my pom.xml (Maven) so that theres no error after compilation and during runtime.
WHat should I do first?
Using the latest Eclipse and I have downloaded both Tomcat 10.1 and OpenJDK 19.
I've set the Java Compiler to openJDK 19 and added both JRE System Library and Server Runtime in the build path.
I have also added some more jar file to fix issues in Marker tab but I encountered error during starting up application.
Tomcat 10.1 uses Servlet API 6.0 which is now part of Jakarta EE. As part of the move from Java EE to Jakarta EE, the packages in javax.servlet.* are moved to jakarta.servlet.* since the error you are getting.
If your target platform is Tomcat 10.1, you should move to Spring Framework 6.

In the process of using WSO2 API Mananger 1.10.0, I scanned out security vulnerabilities. These vulnerabilities occurred on tomcat. The currently embedded version of tomcat is 7.0.59. I want to know how to upgrade this tomcat to solve these security vulnerabilities, such as upgrading the version to 7.0.93 ... I tried to change the pom.xml of product-apim. The version of carbon.kernel.version was updated from 4.4.3 to 4.4.37, but there were new problems in the packaging process. I don't know whether I should update the variables of carbon.commons.version, carbon.registry.version, etc. at the same time.
You shouldn't be upgrading the tomcat version directly as you are doing.
Your WSO2-APIM is very old version which is 1.10.
At that time that tomcat 7.0.59 version was used by wso2. It's better to upgrade your WSO2-APIM to latest 2.1.0 version. Here is the link for the same.
My Springboot application was build in tomcat 9.0 with java version of 1.8 and our server has tomcat 6 with java version of 1.7. I have already downgrade our java version in facet.
How can i downgrade the embedded tomcat in maven? Do I need to generate a new initialize from springIO?
From the SpringBoot docs:
Spring Boot 2.1.1.RELEASE requires Java 8 and is compatible up to Java
11 (included). Spring Framework 5.1.3.RELEASE or above is also
required.
https://docs.spring.io/spring-boot/docs/2.1.1.RELEASE/reference/htmlsingle/#getting-started-system-requirements
So if you must stay on 1.7 and Tomcat 6, you'll need to move away from SpringBoot and back to your older solutions.
I am developing an application under Websphere Application Server v8.0 and I need to use org.codehaus.jackson:jackson-core-asl and org.codehaus.jackson:jackson-mapper-asl version 1.9.2 (mandatory).
On WAS 8.0 such libraries are already included in his runtime, but his version is older. It's 1.6.2 (you can see it in these images):

and
http://i.stack.imgur.com/Vs3TM.gif
I added 1.9.2 jars on the classpath, but the application uses libraries that are bundled in WAS (1.6.2), ignoring the ones in classpath.
Because of this, I can't use some jackson features in 1.9.2 version, that were not in 1.6.2.
My question is: Is possible to configure WAS to not use jackson from his own bundled jars, and let the application to use jars from classpath?
To override the vrrsion provided by the server when called by your application, add the library to an "isolated shared library" then associate it with your app.
Can someone please explain to me the difference in the EAR versions.
Is it tied to the JDK version 1.4, 5 and 6?
Thanks.
It is not JDK version. It is J2EE/Java EE version.
It is asking you which J2EE/Java EE version the ear format (deployment descriptor etc) should adhere to: J2EE 1.2 or 1.3 or 1.4 or Java EE 5 or Java EE 6.
Application servers publish their compliance levels. And some application servers generally support older ear versions as well. For e.g. WebSphere 6.x is J2EE 1.4 compliant but it can still run 1.3 ear version.
enter link description hereWhat application server and version are you looking to ultimately deploy to? You would want the ear to match the level of compliance the target application server is. For example, Oracle 10.1.3.5 Is J2EE 1.4 while JBoss 7 is Java EE 6.0 compliant.
Wikipedia and others attempt to track what each vendor's compliance level is.
