Why Can't I Run My Java Code with Vensim? (Error: Could not find or load main class)

Could Not Find or Load Main Class

Problem:

When attempting to run Java code interfacing with a shared object in Vensim, an error message indicating "Error: Could not find or load main class" appears.

Solution:

Ensure that the path to the .class file is properly added to the classpath. Here's how:

1. Check if the .class file is in the current folder.
2. If it is, add "." (a period) to the classpath.
3. Separate multiple classpath entries with a semicolon (;) if you're using Windows.

Ensure that the modified classpath accurately includes the location of your .class file.

Example Modification:

If your .class file is in the current directory and you're using Windows, modify your classpath to the following:

-cp .;apache-log4j-1.2.16/log4j-1.2.16.jar:./vensim.jar

Remember to separate the classpath entries with semicolons (;) in Windows.
