I'd a custom log4j custom appender, it works in my testing environment like:
C:\Log4jTest>java -cp . Log4jTest

But when configuring it into Karaf, when starting it always throws error: org.apache.felix.configadmin-1.2.8|[org.osgi.service.log.LogService, org.knopflerfish.service.log.LogService, org.ops4j.pax.logging.PaxLoggingService, org.osgi.service.cm.ManagedService, id=8, bundle=4]: Unexpected problem updating Configuration PID=org.ops4j.pax.logging, factoryPID=null, bundleLocation=mvn:org.ops4j.pax.logging/pax-logging-service/1.6.9 java.lang.NoClassDefFoundError: javax/crypto/SecretKey at com.microsoft.azure.storage.Credentials.(Credentials.java:63) at com.microsoft.azure.storage.StorageCredentialsAccountAndKey.(StorageCredentialsAccountAndKey.java:42) ......
My mvn POM.XML is very simple:

[<?xml version="1.0" encoding="UTF-8"?>

And snippet of my org.ops4j.pax.logging.cfg:
....
log4j.appender.hafauditCloudLoggerAppender=com.hcit.logger.CloudLoggerAppender
log4j.appender.hafauditCloudLoggerAppender.Threshold=DEBUG
log4j.appender.hafauditCloudLoggerAppender.TableName=LoggerTable
log4j.category.com.gehcit.haf.audit.consumer = DEBUG,hafauditCloudLoggerAppender ......

I checked that my jre.properties did have the javax.crypto:
......
javax.crypto, \
javax.crypto.interfaces, \
javax.crypto.spec, \
......

I'm new to Karaf, and wonder how to resolve it? my JDK is jdk1.7.0_72 and thanks.

Finally I found the tricks, if changing the config.properties by adding those components like this:
org.osgi.framework.bootdelegation=org.apache.karaf.jaas.boot,sun.,com.sun.,javax.transaction,javax.transaction.,javax.sql.,oracle.,com.microsoft.sqlserver., javax.crypto, javax.crypto., javax.xml., com.fasterxml.*

It works. of course in POM.xml should add the dependency of fasterxml:

   [<dependency>
       <groupId>de.matrixweb.smaller</groupId>
       <artifactId>ant</artifactId>
       <version>0.8.4</version>
    </dependency>]
