Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.databind.JavaType not found
ant, jackson, java, json
Solution
I was getting this error because someone else in some other class was using `org.codehaus.jackson` package and I am using `com.fasterxml.jackson` package. And because of this conflict of jars, it was throwing this `ClassNotFoundException`. Once I removed and replaced those fasterxml jars with codehaus jars, it started working fine.
Problem
I am using jackson libs in my application and when I build the code (using ant), the build is successful. And I have tried mock testing by using those methods in unit testing and its working fine. But when starting karaf, it gives me this error: ``` Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.databind.JavaType not found by com.project.test.application [224] at org.apache.felix.framework.BundleWiringImpl.findClassOrResourceByDelegation(BundleWiringImpl.java:1532) at org.apache.felix.framework.BundleWiringImpl.access$400(BundleWiringImpl.java:75) at org.apache.felix.framework.BundleWiringImpl$BundleClassLoader.loadClass(BundleWiringImpl.java:1955) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ``` And these are the jars I am downloading in my ivy.xml: ``` <dependency org="com.fasterxml.jackson.core" name="jackson-core" rev="2.4.4" transitive="false" /> <dependency org="com.fasterxml.jackson.core" name="jackson-annotations" rev="2.4.4" transitive="false" /> <dependency org="com.fasterxml.jackson.core" name="jackson-databind" rev="2.4.4" transitive="false" /> ``` I have tried changing the versions, but still the same error. Do I have to load these jars after downloading? I have kept the default place as ivy-lib and that process is working for all the other jars I am downloading. What is going wrong? Does this require a specific version or any other dependency? Or is there other way to load these jar files? My classpath in build.xml ``` <path id="compile.classpath"> <fileset dir="${ivy.lib}"> <include name="*.jar"/> </fileset> </path> ```
