Bundles in karaf not able to resolve java libraries

I have java_home set in linux and in bin/karaf script file one entry is:

JAVA_EXT_DIRS="${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext:${JAVA_HOME}/jre/lib:${KARAF_HOME}/lib/ext"

When my karaf is up and running and a flow is tested below error is throw:

Caused by: java.lang.ClassNotFoundException: javax.xml.transform.TransformerFactoryConfigurationError not found..

But this should be provided by rt.jar and rt.jar is present in "${JAVA_HOME}/jre/lib" hence I added same section in JAVA_EXT_DIRS entry. But same error persists.

I should get java libraries from karaf. Help me understanding the cause.

Your bundle needs to import the package javax.xml.transform in its Import-Package statement.

In general you need to import all packages that you actually use, with the sole exception of packages beginning with java., which includes for example java.lang, java.util etc but not javax.*.
