I need to use a custom protocol handler. I set JAVA_OPTS to:
-Djava.protocol.handler.pkgs=com.ibm.crypto.provider
My JAVA_OPTS setting,however, is ignored. This is due to catalina.sh
containing
JAVA_OPTS="$JAVA_OPTS
-Djava.protocol.handler.pkgs=org.apache.catalina.webresources"
The result of catalina.sh is that the jvm has
2 -Djava.protocol.handler.pkgs settings - first the custom protocol
then org.apache.catalina.webresources. The net result being that Tomcat is
started with -Djava.protocol.handler.pkgs=org.apache.catalina.webresources.
1. What is the best way of setting java.protocol.handler.pkgs other than
modifying catalina.sh
Call
org.apache.catalina.webresources.TomcatURLStreamHandlerFactory#addUserFactory(URLStreamHandlerFactory)
to add your custom handler.
2. do i need to set java.protocol.handler.pkgs to just my custom handler
or should it be set to a concatenation of
custom + org.apache.catalina.webresources
If you do it that way, it needs to be both.
3. if a concatenation of handlers is required what is the syntax
