I created a program with windows builder to make a custom classifier using IBM Watson services and everything works fine but I have problems with the classification of an image using that classifier's ID from a text fie.
When I put the custom classifiers ID inside the code it works fine but when I am trying to take that ID from a TextField it won't work.
Here is the code inside the button's action event. The variable String id outputs exactly What is inside the parameters method but it replaces the id (cats_599303326) with the id that is in the TextField but when I put id as an argument in the parameters method, program won't run successfully.
On the other hand, if I comment everything and just output the id String, copy and paste it inside the parameters method, It worked fine.
Why it won't work when I pass the variable id through?
VisualRecognition service = new VisualRecognition(
VisualRecognition.VERSION_DATE_2016_05_20
);
service.setEndPoint("https://gateway-a.watsonplatform.net/visual-recognition/api");
service.setApiKey("{api-key}");
File imagesStream = new File(textField.getText());
ClassifyOptions classifyOptions = null;
String id = String.format("\"{\\\"classifier_ids\\\": [\\\"%s\\\"]}\"", textField_1.getText());
System.out.println(id);
try {
classifyOptions = new ClassifyOptions.Builder()
.imagesFile(imagesStream)
.imagesFilename("Image ")
.parameters("{\"classifier_ids\": [\"cats_599303326\"]}") //inside the parameters method, the goal is to replace cats_599303326 with an id given from a textfield
.build();
} catch (FileNotFoundException e1) {
e1.printStackTrace();
}
ClassifiedImages result = service.classify(classifyOptions).execute();
System.out.println(result);
Error log when putting the variable id as an argument in the parameters method, and as I said before, if I just print the id String, copy it and paste it as an argument in the parameters method program will run successfully but it won't run if i put it as a variable:
