The job parameter contains a path of a file. Here is how my context looks like: <bean id="myBean" class=".....MyBean"> <property name="path" value="file:#{jobParameters['PATH'}/fileName"/> </bean> This is already included in a step scope from a reader that is not included here. The question is. When the class is instantiated, the value passed to the bean is "file:#{jobParameters['PATH'}/fileName" instead the value of jobParameter

It should be pretty straightforward, the parameters are already set when the function is executed, so that should not be a problem. I've tried this: I've also tried to add this in the $('form').submit section: uploader.bind('BeforeUpload', function(up) { up.settings.multipart_params = { 'ordre': ordreibruk, 'mode': m }; }); But to no avail. I'm sure I'm overlooking something really simple, but what? Kind regards

When I do it directly, it returns the value. But when I put the same code into a function, it returns NULL. What happens here? Thanks in advance, Mirko namedlist <- list(a=c("50", "80"), b=c("50")) namedlist$a # returns: [1] "50" "80" myfunction <- function(arg){ namedlist$arg } myfunction(a) # returns: NULL 回答1: You are requesting: namedlist$arg and of course there isn't a component with the name

Also, how do you pass multiple frames to the LSTM thru the CNN? In other works I want to process video frames with an CNN to get the spatial features. Then I want pass these features to an LSTM to do temporal processing on the spatial features. How do I connect the LSTM to the video features? For example if the input video is 56x56 and then when passed through all of the CNN layers, say it comes out as 20: 5x5's. How are

Here is my code (actually I will want to eventually pass to NSString stringWithFormat, but getting an NSLog to work would be good enough for now): - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { // Insert code here to initialize your application [self log:@"blah blah %d", 32]; } - (void)log:(NSString *)text, ... { va_list args; va_start(args, text); NSLog(text, args); } The

My problem is that the code I pass to the webkit page is sandboxed, and so has no access to the variables of my main phantom script. This makes it hard make the scraping code generic. page.open(url, function() { var foo = 42; page.evaluate(function() { // this code has no access to foo console.log(foo); }); } How could I push arguments into the page? 回答1: I've had that exact problem. It can be done with a little trickery, because page.evaluate also can accept a string. There are

What's the equivalent in PowerShell? 回答1: What Bash must be doing is implicitly casting the exit code of the commands to a Boolean when passed to the logical operators. PowerShell doesn't do this - but a function can be made to wrap the command and create the same behavior: > function Get-ExitBoolean($cmd) { & $cmd | Out-Null; $? } ( $? is a bool containing the
