Can't you use
ConstantNameAndType.getSignature(pool), and then
Type getType(String signature)




I am trying to get the type information out of of a ConstantNameAndType...

here is my code so far
      String temp = 
pool.constantToString(((ConstantNameAndType)c).getNameIndex(), 
Constants.CONSTANT_Utf8)
        + " "
     + pool.constantToString(((ConstantNameAndType)c).getSignatureIndex(), 
Constants.CONSTANT_Utf8);
      log("temp="+temp);
      String temp2 = 
pool.constantToString(((ConstantNameAndType)c).getSignatureIndex(), 
Constants.CONSTANT_Utf8);
      log("temp2="+temp2);
      //log("temp2a="+Utility.typeOfSignature(temp2));
      log("temp3="+Utility.compactClassName(temp2));

which prints the following.....
const[18]=c Lmod/dummy/DummyClass; 
inst=org.apache.bcel.classfile.ConstantNameAndType

temp=c Lmod/dummy/DummyClass;

temp2=Lmod/dummy/DummyClass;

temp3=Lmod.dummy.DummyClass;

I am just trying to get the mod.dummy.DummyClass string.  how do I do so? 
If I uncomment the temp2a above it breaks because of other 
ConstantNameAndTypes like the following message when I uncomment temp2a 
above.....

const[18]=<init> ()V inst=org.apache.bcel.classfile.ConstantNameAndType

temp=<init> ()V

temp2=()V
