compile command javac -classpath /home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpcore-4.4.11.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-osgi-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-cache-4.5.9.jar ClientCustomSSL.java somshekar@celsys041:~$ file ClientCustomSSL.class ClientCustomSSL.class: compiled Java class data, version 52.0 (Java 1.8) when I try to run it, it gives below error, do I have to specify the classpath at runtime also somshekar@celsys041:~$ sudo java -classpath /home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpcore-4.4.11.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-osgi-4.5.9.jar:/home/somshekar/akshay/java-jvms/httpcomponents-client-4.5.9/lib/httpclient-cache-4.5.9.jar ClientCustomSSL Error: Could not find or load main class ClientCustomSSL thanks in advance Regards Somshekar C Kadam 9036660538 On Thu, Sep 5, 2019 at 6:33 PM <yo...@yossi.at> wrote: > It seems that you are only putting httpclient-4.5.9.jar in your classpath, > but it has dependencies on other JARs itself.
