how to generate html report if my Junit is not run by Ant but by JunitCore.run

Question

I worked on a project in which testclasses are run via JunitCore.run(testClasses) not via Ant because I have to run the project even with no ANT framework (so no Testng for the same reason). But I still need to create html and xml reports same as JUNIT/ANT. How to generate them in my case?

Right now I found https://github.com/barrypitman/JUnitXmlFormatter/blob/master/src/main/java/barrypitman/junitXmlFormatter/AntXmlRunListener.java may be used to generate xml report. How do I generate html similar to junit-noframes.html? Are there existing methods to convert the TESTS-TestSuites.xml to junit-noframes.html and how? if not, how to generate the html? I do not even find the standard of the html format.

In fact I solved the problem myself in this way:
First I use https://code.google.com/p/reporting-junit-runner/source/browse/trunk/src/junitrunner/XmlWritingListener.java?spec=svn2&r=2 to create TESTS-*.xml Then I write the following code myself to create TEST-SUITE.xml and junit-noframes.html. The idea is make use of API of ANT to create reports without really running test. so far the solution works for me.

      Project project = new Project();
      //a fake project feeding to ANT API so that latter not complain 
      project.setName("dummy"); 
      project.init();

      FileSet fs = new FileSet();
      fs.setDir(new File(reportToDir));
      fs.createInclude().setName("TEST-*.xml");
      XMLResultAggregator aggregator = new XMLResultAggregator();
      aggregator.setProject(project);
      aggregator.addFileSet(fs);
      aggregator.setTodir(new File(reportToDir));
      //create TESTS-TestSuites.xml
      AggregateTransformer transformer = aggregator.createReport(); 
      transformer.setTodir(new File(reportToDir));
      Format format = new Format();
      format.setValue(AggregateTransformer.NOFRAMES);
      transformer.setFormat(format);
      //create junit-noframe.html
      aggregator.execute();
