Problem with getSystemToken() returning NULL

PostPosted:Sat Nov 01, 2014 1:49 pm

I am trying to run an amended Simple Importer script (based on the one at http://wiki.openkm.com/index.php/Cronta ... e_importer).

The script runs fine when executed via the Cron screen in the web-gui via the alert/flash icon (my own debug/trace statements below cut from the log file)....

StdOut: =====AutoImport Script=====
Source folder = /media/data3/scanned/import
Token = null
Target okmPath = /okm:root/2014
Folder = com.openkm.api.OKMFolder@c9ebe22
Target path exists already
Importing /media/data3/scanned/import/2014_10_26_08_52_50.pdf --> /okm:root/2014/2014_10_26_08_52_50.pdf
Imported OK

...but fails when running automatically via the scheduler....

StdOut: =====AutoImport Script=====
Source folder = /media/data3/scanned/import
Token = null
Target okmPath = /okm:root/2014
Folder = com.openkm.api.OKMFolder@c9ebe22
Exception while testing target path
Exception in import : java.lang.NullPointerException<br>

...with the line in question being a call to createSimple() as below...
Code: Select all
try {
  print( "Folder = " + folder.toString() ) ;
  folder.createSimple( token, okmPath ) ;
  print( "Target path created" ) ;
}
The script up to that point is....
Code: Select all
import com.openkm.core.*;
import com.openkm.api.*;
import java.io.*;
import com.openkm.module.db.stuff.DbSessionManager;
 
String token = DbSessionManager.getInstance().getSystemToken();
OKMDocument document = OKMDocument.getInstance();
OKMFolder folder = OKMFolder.getInstance();
 
public void autoImport(String okmRoot, File fldpath) {
	String token = null ;

	try {
		print("=====AutoImport Script=====");
		
		print("Source folder = " + fldpath.toString() );
		print("Token = " + token ) ;
		
		// construct target path and create if needed
		Calendar now = Calendar.getInstance();
		String year = String.valueOf(now.get(Calendar.YEAR));
		
		okmPath = okmRoot + "/" + year ;
		print( "Target okmPath = " + okmPath ) ;
		
		try {
			print( "Folder = " + folder.toString() ) ;
			folder.createSimple( token, okmPath ) ;
			print( "Target path created" ) ;
		}
	}
}
I'm surprised that "Token" is always NULL...? Is this to be expected ? Why would there be a difference in behaviour between a manual execute of the script and an automatic one ?

Look your code:
Code: Select all
String token = DbSessionManager.getInstance().getSystemToken();
OKMDocument document = OKMDocument.getInstance();
OKMFolder folder = OKMFolder.getInstance();

public void autoImport(String okmRoot, File fldpath){

String token = null ;
First you initialize with systemToken and then you set as null, remove the last String token=null.

I have removed that, and now see a valid token string, but still the NULL ptr exception now happens on both a manual run, and a scheduled run... (before at least the manual run via the Execute button was working...)....

StdOut: =====AutoImport Script=====
Source folder = /media/data3/scanned/import
Token = 8740f900-99a1-4f87-90f6-f97d210c1f43
Target okmPath = /okm:root/2014
Folder = com.openkm.api.OKMFolder@c9ebe22
Exception while testing target path
Exception in import : java.lang.NullPointerException<br>

Code is...
Code: Select all
import com.openkm.core.*;
import com.openkm.api.*;
import java.io.*;
import com.openkm.module.db.stuff.DbSessionManager;
 
String token = DbSessionManager.getInstance().getSystemToken();
OKMDocument document = OKMDocument.getInstance();
OKMFolder folder = OKMFolder.getInstance();

public void autoImport(String okmRoot, File fldpath){

	try {
		print("=====AutoImport Script=====");
		
		print("Source folder = " + fldpath.toString() );
		print("Token = " + token ) ;
		
		// construct target path and create if needed
		Calendar now = Calendar.getInstance();
		String year = String.valueOf(now.get(Calendar.YEAR));
		
		okmPath = okmRoot + "/" + year ;
		print( "Target okmPath = " + okmPath ) ;
		
		try
		{
			print( "Folder = " + folder.toString() ) ;
			folder.createSimple( token, okmPath ) ;
			print( "Target path created" ) ;
		}
		catch( ItemExistsException iee )
		{
			print( "Target path exists already" ) ;	
		}
		catch( Exception ex ) 
		{
			print( "Exception while testing target path" ) ;
			throw( ex ) ;
		}

Better if we see the complete stack trace error in catalina.log
I do not see anything strange now in the code, seems right.
I suggest test if path exist or not before creation (OKMRepository.getInstance().hasNode(XXXXX))

Here's the log output from the moment I manually execute the script from the Admin console using the "flash" (lightening) icon....
