java - Trouble with slick.util and lwjgl textures -


so i've started making simple 2-d java game using jlwgl , slick-util. ran problem when trying load in textures place on tiles. using slick util try , load textures in. method using so.

 public static texture loadtex(string path, string filetype) {     texture tex = null;     inputstream in = resourceloader.getresourceasstream(path);      try {         tex = textureloader.gettexture(filetype, in);     } catch (ioexception e) {         e.printstacktrace();     }     return tex; }

i set variable "t" store variable check if texture loading works.

     texture t = loadtex("res/grass64.png","png");

i use glquads method draw textured square.

public static void drawquadtex(texture tex, float x, float y, float width,         float height) {     tex.bind();     gltranslatef(x, y, 0);      glbegin(gl_quads);     gltexcoord2f(0, 0);     glvertex2f(0, 0);     gltexcoord2f(1, 0);     glvertex2f(width, 0);     gltexcoord2f(1, 1);     glvertex2f(width, height);     gltexcoord2f(0, 1);     glvertex2f(0, height);     glloadidentity();     glend(); }

calling drawquadtex...

drawquadtex(t,0,0,64,64);

i encountered error:

"exception in thread "main" java.lang.nosuchmethoderror: org.lwjgl.opengl.gl11.glgetinteger(iljava/nio/intbuffer;)v "

i'm not sure quite going on. assistance appreciated first attempt @ java that's not simple school assignment. if need post else, please let me know.

the slick-util library part of slick2d, deprecated , no longer compatible recent lwjgl versions such 1 appear using. why getting error.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
