LWJGL Rotation: Won't rotate

Question

I'm trying to rotate a object I've made with openGL and LWJGL. My problem is that it does not rotate at all. Here is the code I'm using to draw the object with:

public static void draw() {
    if (active) {
        tex.bind();

        glBegin(GL_QUADS);
        glPushMatrix();
            glRotatef(rotation, 0, 0, 1);
            glTexCoord2f(0, 1);
            glVertex2f(x - (WIDTH / 2), y);
            glTexCoord2f(1, 1);
            glVertex2f(x - (WIDTH / 2) + WIDTH, y);
            glTexCoord2f(1, 0);
            glVertex2f(x - (WIDTH / 2) + WIDTH, y + HEIGHT);
            glTexCoord2f(0, 0);
            glVertex2f(x - (WIDTH / 2), y + HEIGHT);
        glPopMatrix();
        glEnd();
    }
}

Answer 1

glBegin(GL_QUADS);
glPushMatrix();
    glRotatef(rotation, 0, 0, 1);

You cannot call any matrix functions between glBegin and glEnd . Move them to in front of the glBegin call.
