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.

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 using Spring Boot to build an application. I downloaded initialized zip project file from start.spring.io/. When I import the project I am getting the following error. By googling I could hardly understand it is proxy or connection issue. But I am able to open the url in browser.
Some people mentioned to change in settings.xml in maven. My eclipse implicitly comes with maven so I did not install maven separately. I tried adding proxy in eclipse as well. But no luck.
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-jaxrs-1.9.13.jar
jackson-mapper-asl-1.9.13.jar
jackson-xc-1.9.13.jar
javassist-3.18.1-GA.jar
javax.annotation-api-1.2.jar
javax.inject-2.2.0.jar
javax.ws.rs-api-2.0.jar
jersey-client-2.6.jar
jersey-common-2.6.jar
jersey-container-servlet-core-2.6.jar
jersey-guava-2.6.jar
jersey-media-json-jackson-2.6.jar
jersey-server-2.6.jar
osgi-resource-locator-1.0.1.jar
validation-api-1.1.0.Final.jar
I am using the following camel packages in my Maven project:
camel-core
camel-jms
camel-jaxb
camel-quartz
camel-bindy
camel-ftp
And when all these are using version 2.8.0 my server starts up fine and the app works ok. But if I update the camel version to anything higher like 2.10.0 then I get the following exception on startup and not sure which of these is causing this issue:
Caused by: org.apache.camel.TypeConverterLoaderException: Failed to load type converters because of: Cannot find any type converter classes from the following packages: [org.apache.camel.component.file.remote]
Any help would be much appreciated?
Maybe another library of your project is using a different version of camel.
You can check the camel dependency tree of your project with this maven command:
mvn dependency:tree -Dverbose -Dincludes=camel-core
In verbose mode, the dependency tree shows dependencies that were omitted for being a duplicate of another, conflicting with another's version and/or scope, and introducing a cycle into the dependency tree.
Here are some reference links:

I am using STS 3.6.1, Java 7, Grails 2.4.3.
When create a normal Grails project, it works good. However, my Grails project need to depends on other java projects, so I convert it to maven project. After that STS prompt error
Could not find the grails dependency file. This probably means that there is a bad dependency in the pom file.
java.lang.Exception
The maven grails project can be build in grails command.
How to resolve is issue? Or if there is walk around to let grails project depends on other Java project.
