Hi,
I have used "is_null(java_values($javaValue))".
Here are the two functions from my code. The first one
is the one that does not works as it should work.
function getRepositoryFactory(){
global $CFG;
require_once($CFG->dirroot.'/depths/setup/depths_config.php');
$javabridge=get_string('javabridge','depths');
require_once($javabridge);
$myLib=get_string('moodle_jar_file','depths');
java_require($CFG->wwwroot.'/'.$myLib);
$session=java_session();
$rep=$session->get($rep);
if(is_null(java_values($rep))){
try{
$rep=new Java("depths.moodle.RepositoryFactory");
$session->put("rep",$rep);
if(is_null(java_values($rep))){
throw new Exception("Could not create
repository!");
}
}catch(Exception $e){); }
}
return $rep;
}
function getProjectFactory($sesame){
global $CFG;
require_once($CFG->dirroot.'/depths/setup/depths_config.php');
$javabridge=get_string('javabridge','depths');
require_once($javabridge);
$myLib=get_string('moodle_jar_file','depths');
java_require($CFG->wwwroot.'/'.$myLib);
$session=java_session();
$projectFact=$session->get("projectFact");
if(is_null(java_values($projectFact))){
try{
$projectFact=new
Java("depths.moodle.ProjectsFactory",$sesame);
$session->put("projectFact",$projectFact);
} catch (JavaException $ex){
$exStr=java_cast($ex, "string");
echo "Exception occured; mixed trace: $exStr\n";
$trace=new
java("java.io.ByteArrayOutputStream");
$ex->printStackTrace(new
java("java.io.PrintStream", $trace));
print "java stack trace: $trace\n";
}
}
return $projectFact;
}

Hi,

creates it and put in
session.
I think it depends on how you do the check.
is_null(java_values($javaValue)) or
java_is_null($javaValue) or if
(!(string)$javaValue)
will work.
if (!$javaValue)
will not.
