Calling any java method as thread

I have an existing webservices project, with 100+ class files, each one basically runs a query, and return results.
I need to build some new hits that do several various hits asynchronously. Then return data. How can I do this without making a bunch of modifications(or as little as possible) to the various class files. It needs to be done at this webservice level, I can't have the calling applications do the hits asynchronously.

So my visualized solution is something like:
String a =CallAsThread(ClassLoader.SomeClass.getTheseDBConfigs(),ClassLoader.SomeClass2.getTheseDBConfigs2()));

Where CallAsThread calls the 2 different classes as threads, joins them, gets and returns there results or however this can be accomplished.

The secret will be in encapsulation here. You say

>>String a =CallAsThread...

Does this mean that you want the result to be in some way a concatenation of strings that are the results of the independent queries?

To be able to do the way suggested I declared a new thread object passing the Runnable object as a paremeter

      Thread t1 = new Thread (new Runnable() {
public void run() {
                        results1=doThis1();
              }
              }
             );
Thread t2 = new Thread (new Runnable() {
public void run() {
      results2=doThis2();
              }
              }
             );
             t1.start();
             t2.start();
      t1.join();
      t2.join();

Thanks
