cube mapping in LWJGL

I try to add cube mapping to my project but i get one error that i dont know how to fix it
when i comment these few line every thing work fine but when they are in …this error occur
“Exception in thread “main” org.lwjgl.opengl.OpenGLException: Cannot use offsets when Pixel Unpack Buffer Object is disabled”


 GL11.glDisable(GL11.GL_TEXTURE_2D);
        GL11.glEnable(GL13.GL_TEXTURE_CUBE_MAP);
        GL11.glPixelStorei(GL11.GL_UNPACK_ALIGNMENT, 1);
        
        GL11.glTexImage2D(GL13.GL_TEXTURE_CUBE_MAP_POSITIVE_X,0,GL11.GL_RGBA,20,20,0,GL11.GL_RGBA,GL11.GL_UNSIGNED_BYTE,temp.getTextureID());
        GL11.glTexImage2D(GL13.GL_TEXTURE_CUBE_MAP_NEGATIVE_X,0,GL11.GL_RGBA,20,20,0,GL11.GL_RGBA,GL11.GL_UNSIGNED_BYTE,temp.getTextureID());
        GL11.glTexImage2D(GL13.GL_TEXTURE_CUBE_MAP_POSITIVE_Y,0,GL11.GL_RGBA,20,20,0,GL11.GL_RGBA,GL11.GL_UNSIGNED_BYTE,temp.getTextureID());
        GL11.glTexImage2D(GL13.GL_TEXTURE_CUBE_MAP_NEGATIVE_Y,0,GL11.GL_RGBA,20,20,0,GL11.GL_RGBA,GL11.GL_UNSIGNED_BYTE,temp.getTextureID());
        GL11.glTexImage2D(GL13.GL_TEXTURE_CUBE_MAP_POSITIVE_Z,0,GL11.GL_RGBA,20,20,0,GL11.GL_RGBA,GL11.GL_UNSIGNED_BYTE,temp.getTextureID());
        GL11.glTexImage2D(GL13.GL_TEXTURE_CUBE_MAP_NEGATIVE_Z,0,GL11.GL_RGBA,20,20,0,GL11.GL_RGBA,GL11.GL_UNSIGNED_BYTE,temp.getTextureID());

is there any thing wrong?
how can i fix this error?

thank you for your time

What does temp.getTextureID() do?
Also, show your glBindTexture and the glTexParameter calls.

I change my code to this …
but i still dont know what exactly should pass to glteximage2d as last parameter…


temp.bind();
        GL11.glCopyTexImage2D(GL11.GL_TEXTURE_2D,0,GL11.GL_RGBA,0,0,Display.getDisplayMode().getWidth(),Display.getDisplayMode().getHeight(),0);
        GL11.glClear(GL11.GL_COLOR_BUFFER_BIT|GL11.GL_DEPTH_BUFFER_BIT);
        GL11.glTexEnvi(GL11.GL_TEXTURE_2D,GL11.GL_TEXTURE_ENV_MODE,GL11.GL_REPLACE);
            
        GL11.glEnable(GL13.GL_TEXTURE_CUBE_MAP);
        GL11.glPixelStorei(GL11.GL_UNPACK_ALIGNMENT, 1);
        ByteBuffer tocube=ByteBuffer.wrap(temp.getTextureData());
        for(int i=0;i<6;i++){
            GL11.glTexImage2D(target[i],0,GL11.GL_RGB,temp.getImageWidth(),temp.getTextureHeight(),0,GL11.GL_RGB,GL11.GL_UNSIGNED_BYTE,tocube);
        }
        
        GL11.glTranslatef(0.0f,0.0f,-5.0f);                              // Move Into The Screen 5 Units
        GL11.glRotatef(xrot,1.0f,0.0f,0.0f);                        // Rotate On The X Axis
        GL11.glRotatef(yrot,0.0f,1.0f,0.0f);                        // Rotate On The Y Axis
        GL11.glRotatef(zrot,0.0f,0.0f,1.0f);                        // Rotate On The Z Axis
        drawing_cube();

in this code i try to take a screenshot with glcopyteximage and map it on cube and then use cube mapping the rest of code work fine without cube mapping part

and also i dont know what shuold i exactly set with gltexparameter in this case so i leave them default

now i get this error
"# A fatal error has been detected by the Java Runtime Environment:

EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x698366a7, pid=5708, tid=5304"

i dont know what to do…
thank you for your reply…
