opengl - LWJGL - Interleaved VAO/VBO not texturing -

i have been attempting transition game's prototype renderer it's immediate mode testing implementation actual vao/vbo implementation. vbo rendering on screen, refusing texture. below simplest test class shows problem:

public static void main(string[] args) throws exception {      //                          vertx,verty         texx,  texy     float[] data = new float[] {0.0f, 0.0f,     0.25f, 0.75f,                                 0.0f, 64.0f,    0.25f, 1.0f,                                 64.0f, 64.0f,   0.5f, 1.0f,                                  0.0f, 0.0f,     0.25f, 0.75f,                                 64.0f, 64.0f,   0.5f, 1.0f,                                 64.0f, 0.0f,    0.5f, 0.75f};      glfwseterrorcallback(glfwerrorcallback.createprint(system.err));     if (!glfwinit())         throw new illegalstateexception("unable initialize glfw");      long window = glfw.glfwcreatewindow(1600, 900, "test", 0, 0);     glfw.glfwmakecontextcurrent(window);      gl.createcapabilities();      glmatrixmode(gl_projection);     glloadidentity();     glortho(0, 1600, 900, 0, 0.000001, 100);      glmatrixmode(gl_modelview);     glloadidentity();      glblendfunc(gl_src_alpha, gl_one_minus_src_alpha);      int vboid = glgenbuffers();     int vaoid = glgenvertexarrays();      glclientactivetexture(gl_texture0);     glenableclientstate(gl_vertex_array);     glenableclientstate(gl_texture_coord_array);      glbindvertexarray(vaoid);     glbindbuffer(gl_array_buffer, vboid);      glbufferdata(gl_array_buffer, data, gl_static_draw);     glvertexattribpointer(0, 2, gl_float, false, 4*float.bytes, 0);     gltexcoordpointer(2, gl_float, 4*float.bytes, 4*float.bytes);      glbindbuffer(gl_array_buffer, 0);     glbindvertexarray(0);      gldisableclientstate(gl_texture_coord_array);        gldisableclientstate(gl_vertex_array);      gltranslatef(50, 50, 0);      texture t = new texture(test.class.getclassloader().getresourceasstream("test/wallfloor.png"));      while (!glfw.glfwwindowshouldclose(window)) {         glfw.glfwpollevents();         glfw.glfwswapbuffers(window);          glclear(gl_depth_buffer_bit | gl_color_buffer_bit);               glclientactivetexture(gl_texture0);             glenableclientstate(gl_vertex_array);             glenableclientstate(gl_texture_coord_array);                glbindvertexarray(vaoid);             glenablevertexattribarray(0);              t.bind();              gldrawarrays(gl_triangles, 0, 6);               gldisablevertexattribarray(0);             glbindvertexarray(0);              gldisableclientstate(gl_texture_coord_array);                gldisableclientstate(gl_vertex_array);              /* equivelent immediate mode code - works             t.bind();              glbegin(gl_triangles);             gltexcoord2f(0.25f, 0.75f);             glvertex2f(0, 0);             gltexcoord2f(0.25f, 1f);             glvertex2f(0, 64);             gltexcoord2f(0.5f, 0.75f);             glvertex2f(64, 0);              gltexcoord2f(0.5f, 1f);             glvertex2f(64, 64);             gltexcoord2f(0.25f, 1f);             glvertex2f(0, 64);             gltexcoord2f(0.5f, 0.75f);             glvertex2f(64, 0);             glend();             */      } } 

the texture bind call following (where wrap = gl_repeat , filter = gl_nearest):

public void bind() {     glactivetexture(gl_texture0);     glclientactivetexture(gl_texture0);     glenable(gl_texture_2d);     glbindtexture(target, id);     gltexparameteri(target, gl_texture_min_filter, filter);     gltexparameteri(target, gl_texture_mag_filter, filter);     gltexparameteri(target, gl_texture_wrap_s, wrap);     gltexparameteri(target, gl_texture_wrap_t, wrap); } 

having spent weekend googling not finding answer, doing horribly wrong? have tested using immediate mode, still render texture.

in addition, mixing core profile code (glvertexattribpointer) non-core profile (gltexcoordpointer)

but real problem comes wrong stride , offset used. stride defines how large data of 1 vertex is, while offset specifies how far beginning of each vertex actual data starts. in case, every vertex consists of 4 floats stride has 4 * float.bytes. positions first 2 floats in each vertex (offset 0) while texture coordinates 3rd , 4th floats means offset = 2 * float.bytes. correct code somehow (note usage of glvertexpointer instead of glvertexattribpointer):

glvertexpointer(2, gl_float, false, 4*float.bytes, 0); gltexcoordpointer(2, gl_float, 4*float.bytes, 2*float.bytes); 

edit

the usage of vaos wrong. in initialization store glvertexpointer/gltexcoordpointer vao vaoid. in rendering code bind vao 0 instead. attribute settings not present when drawing. in addition, i'm not absolutely sure whether vaos work fixed function calls. in case can remove of vao calls.
