XPath or CSS in Selenium RC with Java is not working

Question

I am trying to automate the following scenario with selenium RC:

1. Open Google home page and enter \"Software\" in search box and then click on search button.

Answer 1

there must be pause ( pause (1) ) or waitForElementPresent between 2 clicks here is working sample for phpUnit. Strange, but clickAndWait does'n work

$this->open("/");
$this->type("q", "software");
$this->click("btnG");
for ($second = 0; ; $second++) {
    if ($second >= 60) $this->fail("timeout");
    try {
        if ($this->isElementPresent("//a[@class='l']")) break;
    } catch (Exception $e) {}
    sleep(1);
}

$this->click("//a[@class='l']");
