I've tried to get rid of this issue but unfortunately could not. What I do
not understand is the following:
The Error says:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/slf4j/LoggerFactory
at
org.apache.camel.support.ServiceSupport.<clinit>(ServiceSupport.java:38)
at
org.example.filexml.CamelWithFileAndXML.main(CamelWithFileAndXML.java:23)
Caused by: java.lang.ClassNotFoundException: org.slf4j.LoggerFactory
I have a dependency as:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.6.6</version>
</dependency>
When I checked the slf4j jar file, the package structure is different from
what the error says. There is no org.slf4j.LoggerFactory but rather
org\slf4j\impl\Log4jLoggerFactory. Am I using wrong libraries?
Regards,
Jothi
