Issue/Introduction

Integrating with third party libraries/JARs may result inClassNotFoundExceptionerrors forTransformerFactoryImpl atruntime.

Resolution

You have couple of options to resolve this issue.

Option 1:

Add the following line to Appnode TRA file and restart the Appnode.

java.extended.properties=-Xmx1024m -Xms128m -XX:PermSize=27m -XX:MaxPermSize=128m -XX:-HeapDumpOnOutOfMemoryError -Djavax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl

Option2:

Add the missing packages [org.apache.xalan.xsltc.trax(2.7.200)] in dependencies tab for the application module's Module Descriptor in Business Studio as shown in the attached screenshot (Filename: depenxalan.png). Recreate the EAR and redeploy the application.
