将多个jar文件添加到类路径

Question

I am trying to add all the jar files in the directory below but I get

Exception in thread "main" java.lang.NoClassDefFoundError: twitter4j/TwitterException error.

I am sure there is TwitterException class inside the .jar file. Is there any error in my classpath syntax ?

mahmut@ubuntu:~/Desktop/Java/TwitterDeneme/bin$ java -classpath "~/twitter4j-2.2.6/lib/*.jar:." GetHashtag

I am using ubuntu and jdk 1.7. I tried the same command in windows and it works flawlessly. Is there anything special to do related to Ubuntu OS?

The * syntax for classpaths is rather limited. Try:

java -classpath "~/twitter4j-2.2.6/lib/*:." GetHashtag
