Multitexuring Using ARB

Hey everyone, i am trying to use multitexture in JOGL and keep getting a compilation error. For some reason the program doesnt not understand what GL.GL_MAX_TEXTURE_UNITS_ARB and what GL.GL_TEXTURE0_ARB are. I have had no other issues with my program except these. I have the following imports and my code is also below. I really appreciate the help and what to thank everyone in advance.

import javax.media.opengl.GL;
import javax.vecmath.Point3f;

	public void draw (GL gl)
	{
		gl.glClear(gl.GL_COLOR_BUFFER_BIT | gl.GL_DEPTH_BUFFER_BIT);
		
		for(int i = 0; i < getNumFaces(); i++)
	    {
	    	LevelFace face = getLevelFace(i);
	    	
	    	if(face.getType() != 1) 
	    		continue;

	    	gl.glActiveTextureARB(GL.GL_TEXTURE0_ARB);
	        gl.glEnable(gl.GL_TEXTURE_2D);
			gl.glBindTexture(gl.GL_TEXTURE_2D, m_textures[pFace->texID].ID);
	    	
	    	gl.glPolygonMode(gl.GL_FRONT_AND_BACK, gl.GL_LINE);
	    	
	        gl.glBegin(gl.GL_TRIANGLE_FAN);

	        for(int j = face.getStartVertexIndex(); j < face.getStartVertexIndex() + face.getTotalVertices(); j++)
	        {
	        	Point3f vertex = getVertex(j);
	        	 	
	        	gl.glVertex3f(vertex.x, vertex.y, vertex.z);
	        }// for

	        gl.glEnd();
	        
	        gl.glPolygonMode(gl.GL_FRONT_AND_BACK, gl.GL_FILL);
	    
	    }// for
		
	}// draw

These constants were promoted into core OpenGL in version 1.3. As described in the JOGL Javadoc, all extensions folded into OpenGL 1.3 and earlier are only exposed via their core OpenGL names. You’re looking for GL.GL_MAX_TEXTURE_UNITS and GL.GL_TEXTURE0.
