Thread: Problems in setting classpath

I am a newbie here. I have a problem and have no idea how to solve it. I am trying to run a code for extracting text from PDF document. In order to compile and run the code, I need to add PDFBox-0.7.3.jar to the classpath. I really hope anyone can help me how to solve this problem. Thanks in advance.

The compilation is successfully done using command as below:

>javac -classpath PDFBox-0.7.3.jar PDFTextParser.java

Then, unfortunately, when I tried to run the code, it ended up to give me these errors. The command used as below:

>java -classpath PDFBox-0.7.3.jar PDFTextParser testing.pdf testOut.txt

Errors displayed
Exception in thread "main" java.lang.NoClassDefFoundError: PDFTextParser

Could not find the main class: PDFTextParser. Program will exit.

I have tried another way by using the command as below without setting the classpath and the different type of errors appear.

>java PDFTextParser testing.pdf testOut.txt

Thank you so much for the information. Actually, I have solved the problem. On the run command I've missed to put ; after .jar. Simple mistake
