In order to use APR connector or NIO+JSSE+OpenSSL connector in an embedded application, one has to:

• download standalone Tomcat distribution zip
• extract lib directory from that zip
• set LD_LIBRARY_PATH
• run one's embedded web application

e.g.

unzip jws-application-server-4.0.0-CR1-RHEL7-x86_64.zip jws-4.0/tomcat/lib* -d /tmp/tomcat-libs
export LD_LIBRARY_PATH=/tmp/tomcat-libs/jws-4.0/tomcat/lib/
java -jar target/embedded-tomcat-app.jar

It is exceedingly cumbersome. Could we device a better way? Is it feasible to package .so files inside some jar and put that jar in the Maven repository and let the web app to depend on it? For example, see wildfly-openssl-1.0.3.Final-SNAPSHOT.jar and its:

    win-x86_64/
    win-x86_64/wfssl.dll
    win-x86_64/wfssl.exp
    win-x86_64/wfssl.lib

Simplified example

While the size of the Wildfly-OpenSSL project is quite intimidating, one can take a look at a dead-simple Linux+Windows demo hobby project streamlining the procedure to the bare minimum: https://github.com/Karm/CRC64Java
