How to run multiple @ test simultenously in selenium rc + junit

here is my code...



package com.segurosbolivar.simon.testSuits;



import com.segurosbolivar.simon.util.SimConstantos;
import com.thoughtworks.selenium.*;
import org.junit.After;

import org.junit.Test;
import org.junit.experimental.theories.ParametersSuppliedBy;
import org.junit.runner.RunWith;

public class SimLoginTestSuit extends SeleneseTestCase {
public SimLoginTestSuit(String testCase) {
super(testCase);
}

/*@Before
public void setUp() throws Exception {

}*/

@Test
public void testSimLoginTestSuit() throws Exception {
selenium = new DefaultSelenium(SimConstantos.HOST_NAME, SimConstantos.BROWSER_PORT, SimConstantos.BROWSER_CHROME, SimConstantos.APP_BASE_URL);
selenium.start();

selenium.open("/SimonWeb/login.html");
selenium.captureEntirePageScreenshot("D:\\fullscreenshot","background=#CCFFDD" );
selenium.windowMaximize();
selenium.click("id=submit");
selenium.waitForPageToLoad(SimConstantos.PAGE_LOAD_WAIT_TIME_MILI_SECONDS_90000);


}
@Test
public void testSimon_Product() throws Exception {
System.out.println("mai aaya");
System.out.println("mai aaya"+selenium.toString());
selenium.open("/SimonWeb/home.jsf");
System.out.println("mai gaya");

selenium.click("id=j_idt76:j_idt82");
selenium.windowMaximize();

selenium.click("//div[@id='dynamicMenuform:Product']/span[2]");
selenium.waitForPageToLoad(SimConstantos.PAGE_LOAD_WAIT_TIME_MILI_SECONDS_90000);
System.out.println("mai aaya");
System.out.println("mai aaya"+selenium.toString());

verifyTrue(selenium.isTextPresent("Search Products"));
Thread.sleep(5000);

System.out.println("i am in test 2");
selenium.select("id=searchForm:sectionList", "label=805-PLANES TRADICIONALES");
Thread.sleep(5000);
selenium.select("id=searchForm:productList", "label=455-fyuty");

I want to run this one by one

i have used following two ways to do so but i am failed to run all the test together.
but failed it is entering into second @test but is throwing error of id not found.if i place all the code in one test it is running smoothly pls help

following are the two java classes which are used to run it but they are still showing the same result

1.package com.segurosbolivar.simon.testSuits;


import junit.framework.Test;
import junit.framework.TestResult;
import junit.framework.TestSuite;

public class SimTestSuitMain {

public static Test suite() {
TestSuite suite = new TestSuite(SimLoginTestSuit.class);
//TestResult result= suite.run(suite);
http://suite.addTestSuite(SimLoginTestSuit.class);
http://suite.addTest(new TestSuite(SimLoginTestSuit.class));

http://suite.addTest(com.segurosbolivar.simon.testSuits.SimLoginTestSuit.SimTestSuitMain.suite());

http://suite.addTest(new SimLoginTestSuit("testSimLoginTestSuit"));
http://suite.addTest(new SimLoginTestSuit("testSimon_Product"));
http://suite.addTest(new SimLoginTestSuit("testSimon_Search_Product"));

return suite;
}

public static void main(String[] args) {
junit.textui.TestRunner.run(suite());
}
}

2.
package com.segurosbolivar.simon.testSuits;

import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;

@RunWith(Suite.class)

@SuiteClasses({ SimLoginTestSuit.class})
public class AllTests {

}
