First off, have you tried using a better decompiler? I'd recommend Krakatau, since it's specifically designed for handling obfuscated applications (disclosure: I wrote it). Apart from Krakatau, the best decompiler I know of is Procyon.
Second, you can see the constant pool by passing the right option to the disassembler. If you're using the Krakatau disassembler, you'd just pass -cpool. You can also use javap in which case you'd pass -v. However, javap is not designed for reverse engineering and has numerous issues, so you're better off with Krakatau for serious disassembly.
