I have a java jar file which I am trying to run from exec in a PHP script when a user clicks on a map. The application runs fine and generates the GeoJSON as intended, but from exec I get an error half way through the script:

When I run the file as a Java application, all the console prints tell me that the script is running as intended, producing extra features and setting the attributes, outputting the GeoJSON at the end.
However, when run from exec it only executes the code correctly up to line 176 and then fails.
I have Googled what the problem might be but there is very little online related to clazz references like this so apologies if I can’t be more explicit but I’m not sure what the problem might be.
EDIT:
I realised the problem – I was trying to update the attributes of the datastore objects rather than creating new ones and adding the new SimpleFeatures to an arraylist. After building new features, the script ran fine from exec.
My PHP script is:
<?php
$siteid = isset($_POST["siteid"]) ? $_POST["siteid"] : 0;
strval($siteid);
$format = "java -jar C://Users//antjs//eclipse-workspace//DevMapWebsite//jars//createsites.jar ";
$string = sprintf($format, (strval($siteid)));
exec($string, $result);
$myarr=json_encode($result);
echo $myarr;
print_r($result)
?>
“The error message is caused by this line:” I rather doubt that, since the exception’s message says it occurred at a line containing
clazz.isArray(). Edit your question and show us the entire stack trace for the exception.Ok I’ve added all the stack trace and all the entire script, hope you can help…
Hard to tell what’s happening here. I would start by printing out the value of
newtwositesfeaturegeom, to make sure it isn’t null.
