I'm trying to use IBM Rational Application Developer version 9.0 with WebSphere Application Server v7.0 running Java 1.6 and use JAX-RS with org.glassfish.jersey version 2.6. This is not a maven project, so I created another maven project, added the root dependencies there and built it so it pulled down all of the jars. I moved them over into my non-maven project.
When I run the project, I start the server (or try to hit a resource) I get the following error message: java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=org/glassfish/jersey/jackson/internal/JacksonAutoDiscoverable, offset=6
I have a different application that successfully uses jersey deployed WAS7 on this same machine. I've compared the project and server configurations and see no major difference, particularly no difference in the Installed JRE", Execution Environments or Java Compiler Compliance Level (all using 1.6).
Even though the maven project is using jersey 2.6, I have also tried other lower jersey versions in the non-maven project to see if it's an issue with the dependencies being built for 1.7 but that doesn't seem to be the case at all.
Here is the list of dependencies I have in my library:
aopalliance-repackaged-2.2.0.jar
hk2-api-2.2.0.jar
hk2-locator-2.2.0.jar
hk2-utils-2.2.0.jar
jackson-core-asl-1.9.13.jar

jackson-mapper-asl-1.9.13.jar

I am trying deploy my Spring Boot application to Elastic Beanstalk.
The problem that I am facing right now is, my application is developed with Tomcat 9, Java 13 and Project Facet 4.0.
So when I deployed to a AWS environment, I kept getting error. After researching, I found out AWS only support Tomcat 8, Java 8 and Project Facet 3.0.
I managed to change Project Facet 4.0 to 3.0.
But I can't add Java 8 to the project.
I downloaded the JDK 8 from Oracle, and tried open jdk-8u251-macosx-x64.dmg and run JDK 8 Update 251.pkg.
The system keeps giving me error that: "JDK 8 Update 251.pkg" can't be opened because Apple cannot check it for malicious software. This software needs to be updated.
Anyone know how to fix this problem so that I can run JRE 8 on eclipse?
Here is picture the problem that I have when I deploy the app to AWS.
An internal error occurred during: Updating AWS Elastic Beanstalk environment
Here is the thread that I tried to follow but without success:
https://github.com/aws/aws-toolkit-eclipse/issues/149.
Can you elaborate where exactly are you seeing the error? While running the JDK package or while configuration the JDK within Eclipse?
Nevertheless, I suppose your main requirement is to get your Eclipse to use Java 8.
It can be done in multiple ways.
Usually you can change Java compiler level to 1.8 from Project Settings even if you're using Java 13.
If you're using Maven, you can specify compiler source and target to Java 1.8
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
Alternatively, you can download the JDK 8 zip instead of installer, unzip to any location and use that in Window > Preferences > Java > Installed JREs. Be sure to mark that one as default JRE.
I have created a Spring Starter data jpa project and its connecting with mysql. through STS its running fine.
i wanted to deploy it individually so i clean install the application using maven and used java jar <jarfile.jar> in command prompt.
I followed the video of java brains.
Below is the error which get
JAXB is not found.
It seems that you set the scope of the JAXB dependency to provided or built the project for an old Java Version (like Java 8) that comes with JAXB and run it with a newer Java version (like Java 10) that does not come with JAXB.
You can fix this by adding the JAXB dependency to the classpath when running the JAR or by adding the dependency to your project manually(or set the scope to compile)
I am developing an application for MULE ESB CommunityEdition (3.8.1 version).
I have included (provided by MULE) SPRING 4.1.6.RELEASE in project.
For persistence layer I set up Hibernate 4.3.11.FINAL.
My code is based on this idea (https://www.ricston.com/blog/jpa-mule/).
So basically i have included in the project (besides MULE dependencies):
hibernate-entitymanager (4.3.11.Final)
hibernate-core (4.3.11.Final)
hibernate-jpa-2.1-api (1.0.0.Final)
spring-orm (4.1.6.RELEASE)
And everything was working perfectly fine until i started to use Java 8 API...
Whatever I do: any lambda, stream or anything I am still getting error:
org.hibernate.jpa.boot.archive.spi.ArchiveException: Could not build ClassFile
What I did until now:
tried to add org.javassist dependency (in version from 3.18.0-GA to 3-22.0-GA) - nothing happened,
tried to exclude org.reflections.0.9.9 dependency (mule is including that in some its core dependencies): also nothing happened
I spent on this about 5 hours I am really close to give it up... I really need hibernate cause this project will include many db operations
What else Can i Try to do?
Problem solved!!
I was using mvn dependency:tree to check if there are any org.javassist dependencies in project.
And there weren't...
Then I checked the folder: {mule_home}/lib/opt and there was an old version of org.javassist library!
So: I downloaded latest org.javassist jar and I put it in the {mule_home}/lib/user folder.
Now it works like a charm :)
Please check if your Anypoint Studio is pointing correct JDK.
Check below
Preference> Installed JRE >> It should have JDK 1.8 checked.
I am not good at all this web stuff, but I have managed to port a small Spark-tinyweb application to serve REST services from jetty to Tomcat, following the project from Leonan Luppi in
https://github.com/leonanluppi/SparkTomcat
But in the folder WebContent/WEB-INF/lib, if I replace the file
spark-core-2.1.jar
to a newer version:
spark-core-2.5.jar
The application does not work.
Any suggestions?
Your build.gradle file specifies the dependency on com.sparkjava:spark-core:2.1. You have to upgrade the version in the file too so that Gradle can resolve the dependencies and compile your app.
I have a Jersey (1.4) app deployed on Tomcat 5.5, when Tomcat starts up I can see its loading all the resources and providers. But as soon as I access any of the web services I get this strange error
java.lang.NoClassDefFoundError: com/sun/jersey/spi/inject/Errors$Closure
I spent good long time finding out what's going on but had no luck.
I converted maven project into eclipse project using mvn eclipse:eclipse -Dwtpversion=1.5.
Any ideas?
I got this error when I also had a nuxeo related dependancy in my maven pom.xml, which itself has a dependency on jersey libraries, but at an earlier version (1.1.5 to be specific).
I changed the pom to depend on the latest version of jersey-core, jersey-server and jersey-client dependencies and ran mvn eclipse:eclipse and the problem went away!
There must have been a class clash involved.
