I'm trying to send an email using JavaMail API. I have jdk 1.5 installed in my home directory from self-extracting binary. I'm on Ubintu 9.10

I compile the program using the next command:

~/jdk1.5.0_22/bin/javac -classpath ~/jdk1.5.0_22/jre/lib/javamail-1.4.3/mail.jar:~/jdk1.5.0_22/jre/lib/jaf-1.1.1/activation.jar hw.java

It compiles OK. As you can see I have specified the path to mail.jar and activation.jar Now I try to run the app using the next command:

~/jdk1.5.0_22/bin/java -classpath ~/jdk1.5.0_22/jre/lib/jaf-1.1.1/activation.jar:~/jdk1.5.0_22/jre/lib/javamail-1.4.3/mail.jar:. HelloWorldApp

I get an exception java.lang.NoClassDefFoundError: javax/mail/Add开发者_如何转开发ress

Why can it find classes when compiling and cannot do it when running? How to correctly run my app?

Thanks in advance


That class should come from your mail.jar. I'm not sure your classpath is being parsed properly. The tilde (~) is a shell function and needs expanding before being sent to the Java process. Have you tried removing the ~ and replacing with /home/{whatever} ? I suspect that's the issue.
