I need to use Stanfordparser.jar, pdfbox.jar, FontBox.jar in my web application. I’m developing this web app on Netbeans und using tomcat 7.0.22 server, I have include all those .jar file in both WEB-INF/lib AND Libraries Folder (But webapp uses .jar in the libraries folder), The web app runs fine on local machine. But when I run the .war file in WSO2 Stratoes live server and go to the JSP page that uses the .jar file ,it give this error.
java.lang.NullPointerException

Putting .jar files just in WEB-INF/lib is enough? Or do I need to point them in the web.xml file? Or how do I overcome this issue?
Update
this is my code
String url = "jdbc:mysql://rss1.stratoslive.wso2.com/karshamarkuptool_karsha_opensource_lk";
String username = "root2_lQrhzZUK";
String password = "nbuser";
BasicDataSource ds = new BasicDataSource();
ds.setDriverClassName("com.mysql.jdbc.Driver");
ds.setUrl(url);
ds.setUsername(username);
ds.setPassword(password);
byte[] b = null;
try {
b = getBLOB("2");
} catch (Exception ex) {
Logger.getLogger(ControlerServelet.class.getName()).log(Level.SEVERE, null, ex);
}
492 //ArrayList<String> sentenceList = new ArrayList<String>();
493 ArrayList<String> sentenceList;
494 parseDocument doc = new parseDocument(); // Parse document object this has the external dependencies
495 sentenceList=doc.pdfDocToSentence(b);
499 // sentenceList.add("test string");
500 request.setAttribute("allphrases", sentenceList);
I have commented out line 499 and modified 492 to 493. Now web page shows no error, But a blank page. Rest of the pages works fine
I'm using netbeans IDE and added external jar files to project's Libraries folder too. Althought I have jar files in WEb_INf/lib folder, the clases are using the external libraries from project folder's Library folder, Can this be a problem? do i need to point servelet classes to use the libraies from WEB_INf/lib folder?
