Just started with Camel yesterday and am trying out various examples given in
the camel download. It has been frustrating so far that I can't get to first
step of being able to deploy basic examples. Any help would be greatly
appreciated.
I started with camel-example-cxf-tomcat.
Here are my versions:
camel-2.11.0
jdk1.7.0_21
maven-3.0.5
mycode
tomcat-6.0.37
I copied the camel-example-cxf-tomcat into mycode directory and built it
with 2 ways (different times)
-mvn clean install
-mvn package
and, copied over the war file to the tomcat directory. No build problems so
far.
when I try to startup tomcat, I see errors in the log that says:
Jun 24, 2013 7:56:48 AM org.apache.catalina.loader.WebappClassLoader
clearReferencesStaticFinal
FINE: Could not set field LOG to null in class
org.apache.camel.component.file.GenericFileConverter
java.lang.ExceptionInInitializerError
at sun.misc.Unsafe.ensureClassInitialized(Native Method)
Caused by: java.lang.NullPointerException
at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:270)
I can post the build log, but there were no errors during the build.
