Solution 1
Find Sunjce, copy it to lib, and run the solution.

echo $JAVA_HOME  
> find $JAVA_HOME -iname "*sunjce*jar"   # find sunjce

Just copy this into lib.
Solution 2
You just have to load the JAR package under Ext, otherwise it’s a problem.
for example: java-java.ext.dirs =lib:$JAVA_HOME/jre/lib/ ext-jar build/ myappjar.jar

    cp makes use of the current jar package and the lib/ext directory jar package in the jre, -d does not. Copy the past jar
