Help with Debugging An Error 500

[Michele Smith]

Hello I received this error:

java.lang.NullPointerException
bcc.lib.Context.getDisplayLifeReviewForUser(Context.java:932)
bcc.lib.NavBar._generateHTML(NavBar.java:145)
bcc.lib.NavBar.getHTML(NavBar.java:114)

I have read the server log and it says that the servlet

SelectReporting.java has thrown an exception.

The code for the SelectReporting.java file is as follows:

package bcc.pages;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.List;
import java.util.ArrayList;
import java.util.Iterator;

import com.bc.util.BcSQLAgent;
import com.bc.util.logging.Logger;
import bcc.lib.Context;
import bcc.lib.dob.Case;
import bcc.lib.dob.CaseDMDocuments;
import bcc.lib.dob.Home;
import bcc.lib.dob.TransFiles;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;


public class SelectReporting extends bcc.lib.BasePageJQuery
{
	protected String getBanner( Context ctx, BcSQLAgent agt, HttpServletRequest req )
	{
		return "General Reports";
	}

	protected String getContent( Context ctx, BcSQLAgent agt, HttpServletRequest req, HttpServletResponse res ) throws Exception
	{
		try
		{
			StringBuffer sb = new StringBuffer();
			
			sb.append("<Reports>");
			addStateInformation(sb, ctx);
			Home h = ctx.getHome(agt);
			
			h.getXML(sb);

			sb.append( "</Reports>" );

      Logger.finest( this, "getContent", "XML =\n" + sb.toString() );

			return ctx.parseStylesheet( agt, "SelectReporting.xsl", sb );
    }
    catch ( Exception e )
    {
			throw e;
    }
	}

	protected String getNavBarItem( Context ctx, BcSQLAgent agt, HttpServletRequest req ) throws Exception
	{
    return "SelectReporting";
	}
}

For what it is worth, this file is identical to another file which is being used.

Thanks,

No offense, but shouldn't you be able to read an exception stack trace by now? I'm pretty sure you've been told how to before (like in https://coderanch.com/t/589491/Servlets/java/HTTP-Status).

In fact, this seems to be that same question. Please continue the discussion in that topic and please do not post the same question twice.
