Answer 1

As others have pointed out you have to include the jar files that come along with the CORE-NLP package that is avalaible at the stanford parser page.

More specifically add these to your class path : stanford-parser-3.4.1-models.jar,stanford-parser-3.4.1-sources.jar,stanford-parser.jar ( these are specific to the version of stanford parser you are using i.e version 3.4.1 )

You can add it to the class path as follows :

For Linux : export CLASSPATH=$CLASSPATH:/some_path/stanford-parser-3.4.1-sources.jar:/some_path/stanford-parser-3.4.1-models.jar:/some_path/stanford-parser.jar

For Windows : set CLASSPATH=%CLASSPATH%;\some_path\stanford-parser-3.4.1-models.jar;\some_path\stanford-parser-3.4.1-sources.jar;\some_path\stanford-parser;
