Screenshot of program error

After I updated the algorithm.jar provided by programmers, an error message (java.lang.NoClassDefFoundError) popped up when I use "Find Shortest Path" command. The screenshot of error message is attached.


Procedure to reproduce the error:
1. Open Eclipse, open GraphAnalyzer project
2. Right click the GraphAnalyzer project in "Package Explorer", choose Properties
3. Select "Java Build Path" in the tree, choose "Libraries" tab"
4. Click "Add External JARs..." and browse the "algorithm.jar" file
5. Click "Apply and Close"
6. Run the program
7. Type "C|f|C:\testing\graph3.txt" to insert graph
8. Type "SP|d|3|1|4" to use the shortest path command
9. After entered the command, the java.lang.NoClassDefFoundError is occurred.
