I am using TestNG with ant to run Selenium scripts.

Selenium jars are located 2 directories down below ant build file.

My ant build file location: \perforce\WebEng\monthly\javaweb
Selenium jars location: \perforce\WebEng\monthly\javaweb\qa_test\lib

If I start selenium server manually and run TestNG+ant script, "ieahta" works fine.

However, selenium.start() in "iehta" mode fails when I start server programmaticaly from within TestNG+ant script.

Exception:

Exmple of my code:
SeleniumServer server = new SeleniumServer(4444);
server.start();
sleep(10000);
SeleniumServer.setForcedBrowserMode("*iehta");
QAReporter.log("CREATING BROWSER SESSION (executed browserSession = new DefauttSelenium(localhost,4444, *iehta,()...");
DefaultSelenium browserSession = new DefaultSelenium("localhost",4444, "*iehta","http://qa.test.com/Login");
sleep(10000);
QAReporter.log("BROWSER STARTUP (executed browserSession.start())...");
browserSession.start();
sleep(10000);
QAReporter.log("SERVER MODE2:"+SeleniumServer.getForcedBrowserMode());
