Editor does not contain a main type

If you get an error "editor doesn't contain a main type" in eclipse,
solution is :
1) Make sure eclipse created the project as Java project.
2) Just create a new Java project and copy your class into the src folder by import the eventual dependencies and adding all the jar files to it.

This should fix the problem.

    It works fine with SRC because all the java files are placed in it, means all the source files are contained in it and as you know "main" is entry point for every program. So, it looks for main at first glance. "SRC" is the by default directory of the project folder to store all the raw files.

Waiting for the last reply... ERR unknown command ' *2' ERR unknown command '$4' ERR wrong number of arguments for 'echo' command ERR unknown command '$20' ERR unknown command ' A�j d�Q;yT��าก �h>' NOTE: command line will show error but in actual the data is transferred and you can check it by entering in redis. Here's the snapshot of the whole procedure: To check how the command is responding: use hexdump -C Command: echo -n $'$3\r\nset\r\n$3\r\nkey\r\n$5\r\nvalue\r\n ' | hexdump -C whose output will be something like 00000000 24 33 0d 0a 73 65 74 0d 0a 24 33 0d 0a 6b 65 79 |$3..set.....
