There is no JSESSIONID in the content of HTTP response after a bad request.

[aaaakun]

Hello,
thanks for your great work to apply such an useful API.
I found an issue when using the API.
Firstly I used the API to make a mistake on purpose, for example, I added a role which already exsited on the server.
After that whatever API I used, there is no JSESSIONID in the content of HTTP response.
So that I cann't use SPRING authenticate type to connect with sever after a http error.

In the JasperserverRestClient class, if AuthenticationType is SPRING, the follwing codes will work:

String sessionId;
if (!location.matches("[^?]+\?([^&]&)error=1(&[^&])$")) {
sessionId = response.getCookies().get("JSESSIONID").getValue();
storage.setSessionId(sessionId);
} else {
throw new AuthenticationFailedException("Invalid credentials supplied. Could not login to JasperReports Server.");
}

This will cause NullPointerException.

Could you please tell me what's the reason of this problem?
Looking forward for your reply.

Could you provide us with your code? from HTTP is not completely clear, what is going on. in short words, you can not get JSESSIONID from any request, you have to get object "session" after login. Or attach Base64 encoded credentials as header, but in this case you don't need JSESSIONID at all(each request works in separate session).

Thank you for you reply.
We found that the API seems like to have a conflict with javafx.scene.web.WebView.
And the conflict causes JSESSIONID's missing.

Code(1112 is an exsiting role):

public static void test() {
new Thread(() -> {
try {
ClientRole roleCreate = new ClientRole().setName("1112");
client.authenticate("superuser", "superuser")
.rolesService()
.roleName("1112").createOrUpdate(roleCreate);
} catch(Exception e) {
String detailHTML = "";
Platform.runLater(() -> {
WebView webView = new WebView();
webView.getEngine().loadContent(detailHTML);
webView.setMaxHeight(400);
webView.setMinHeight(100);
});

			client.authenticate("superuser", "superuser")
	        .organizationsService()
	        .allOrganizations()
	        .parameter(OrganizationParameter.INCLUDE_PARENTS, "true")
	        .get();
			try {
				Thread.sleep(5000);
			} catch (InterruptedException ex) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			client.authenticate("superuser", "superuser")
	        .organizationsService()
	        .allOrganizations()
	        .parameter(OrganizationParameter.INCLUDE_PARENTS, "true")
	        .get();
		}
	}).start();
}
