Adding jar files in each jvm run dont seem to work

vonhact Published in 2017-12-07 10:01:46Z

I hava a java program which requires me to add an additional jar file when I run it.

What I first do is:

$ javac -classpath postgresql-42.1.4.jar myFile.java

It executes with no errors. But when I then try to do:

$ java -classpath postgresql-42.1.4.jar myFile

It says:

Error: Could not find or load main class myFile

The current folder im in looks like this:

postgresql-42.1.4.jar myFile.class myFile.java

There are no errors in myFile.java file (it is setup correctly).

You've overridden the classpath, so it only contains the driver. You need to include your current directory there as well.

java -cp postgresql-42.1.4.jar:. myFile

Also please adhere to Java naming conventions. It should be MyFile, not myFile.
