You have to supply the resource's full path in the command.

edu/stanford/nlp/models/lexparser/englishPCFG.ser.gz

When Java tries to find something, it looks for that path in all of the jar files in the CLASSPATH. Also the -cp "*" will only work if you are executing the command in the directory with all of the .jar files.
