Batch Processor script error

Classic Servoy
1

Hi all,

I have written a simple test scheduler script to store file on a windows machine every minute. When I execute the methods on the client it works fine.

When I execute as a Batch Process using Servoy Server admin interface. I get the following error on the server log

I tried to extract the file.jar in order to check the error for com.servoy.extensions.plugins.file.FileProvider.js_writeTXTFile(FileProvider.java:647). But there was no java files provided along with the class files

This is the function that is executed on startup:

function test()
{
       //My startup script on open of the solution
	var batch_command = arguments[0];
	if(batch_command == "test")
		{
		 globals.create_cron_jobs();
		}
}

function create_cron_jobs()
{
	plugins.scheduler.addCronJob('1min','0 0/1 * * * ?',globals.cron_method);
}

function cron_method()
{
        // Method that creates the file on the PC machine
	var fileName = 'test.txt';
	var filePath = plugins.file.getDesktopFolder();
	filePath +="/" + fileName;
	plugins.file.writeTXTFile(filePath,'test');
}

function remove_cron_jobs()
{
	plugins.scheduler.removeJob('1min')
}

On the Servoy admin Batch Processor interface I have the following parameters sets
Solution: test_solution
args: test
User: Admin
Startup Msg: -Empty-
Status: Is running

when i check the logs it actually runs the cron_method() every 1 minute and throws the error on the server log file.

Any help would be appreciated?

Please James, don’t cross post!
It makes the forum less informative…

Sorry about that.
