Question

I have a program like this –

import weka.core.stemmers.SnowballStemmer;

public class TestProject{
public static void main(String[] args) {    
   String testString = "shortly";
      SnowballStemmer stem = new SnowballStemmer();   
      String text = stem.stem(testString);
      System.out.println(text);
   }
}

This program executes and I get the following output –

My question is how to remove those 5 lines of errors that are printed when the program executes?

I am not using any database.

Thank You,

Not sure if this is the right thing to do because if adding snowball.jar initialize the database connection, probably snowball need that connection for a reason. But anyway, here is a workaround if you want that five lines of errors not to be printed.

• make a copy of DatabaseUtils.props, you can find it from weka.jar /weka/experiement/DatabaseUtils.props
• place this properties file in your classpath. For example in eclipse, place it at the root of the project.
• commented out all lines start with jdbcDriver.
• added a line jdbcDriver=

When I execute the class file with the properties file in place, this is the output.
