Ty Limbic~Region for the post. I wasn't aware I needed to run the Selenium core. I did try running $netstat -an | grep LISTEN | grep 4444 and it didn't do anything so I figured I really didn't have the Selenium core.

I tried running the $java --jar selenium-core.jar suggestion from my terminal but I got the following error:

Unrecognized option: --jar Could not create the Java virtual machine.
I guessed you meant "-jar" rather than "--jar" so I retyped the command at the terminal but I got the following:

The program 'java' can be found in the following packages: * gij-4.3 * java-gcj-compat-headless * openjdk-6-jre-headless * cacao * gij-4.2 * jamvm * kaffe Try: sudo apt-get install <selected package> bash: java: command not found

So I tired "sudo apt-get selenium-core" hoping this would work but it didn't. So the next thing I did was try searching the Synaptic Package Manager with no luck. I then googled and found http://release.seleniumhq.org/selenium-core/1.0.1/selenium-core-1.0.1.zip. I downloaded it and extracted but I couldn't make heads or tails of what to do next after reading the 'install-readme.txt.'

Any advice on how I actually install Selenium core on Ubuntu? All my other searches for information on this didn't result in anything I could use.

Also assuming that I get Selenium core running, is there any code I need to know about to "start" the Selenium core? I can't remember where I read it, but I read that you need the following code in your perl program:

$sel->start();

If so, where do I put it? I put it in my program here:

my $sel = Test::WWW::Selenium->new( host => "localhost", port => 4444, browser => "*chrome", browser_url => "http://www.example +.com/" ); $sel->start(); $sel->open("/home/index.jsp");

Did I get this code position correct?

Many thanks for the help!

    icleave,

    There really isn't anything to install. You just download the jar files and run them. Looking at the error message you got, I would guess you don't have Java installed. You need to install Java to run Selenium. WWW::Selenium is a perl interface to Selenium Remote Control only.

    Did I get this code position correct?

    Yes. You should always check the SYNOPSIS in TFM which shows you the typical usage.

      Thanks for the tips! I finally figured it all out except for the class path stuff (I have no idea how to create a java classpath to the .jar file) but I eventually experimented until I figured out that I can run one terminal running selenium rc and open another terminal and run my perl code from that.

      Low and behold my perl code comes to life and firefox loads up... only to die time and time again with a popup box that loads when you click 'login' on the website I'm trying to automate access to. After spending a whole day learning about how you need to select the popup box and close it, then select 'null' to get back to the original browser window I just can't seem to get my perl/selenium code to do what I want. The main issue is that upon clicking the 'logon' link at the website I'm trying to automate access, it is random event where by:

      1. No popup box pops up, or
      2. A popup box named 'stealth' pops up, or
      3. A popup box named 'entry' pops up.

      I found that selenium is very fragile when it comes to coding the next step for it to preform... if I run my code without any mention to a popbox then everything is fine, but when I run the code and a popup box happens then it dies with a "255" exit message. Looking around the options in the IDE I couldn't see any program flow commands for selenium IDE so after going to the selenium website it seemed to me that program flow must come from the coding language you are using.

      So I thought, ok, Perl has program flow commands, why not use the "if" statement and "elseif" and "else" for all three possibilities:

      1. no popup
      2. popup "stealth"
      3. popup "entry".

      I coded it up as best as I could in Perl but then I got syntax errors where my blocks where. I was under the impression that something like $sel->title_is("Entry") would give perl a 'true' or 'false' and operate the program flow accordingly. Please help, I'm quite confused, a sample of the code is below:

      my $sel = Test::WWW::Selenium->new( host => "localhost", port => 4444, browser => "*chrome", browser_url => "http://www.example +.com/" ); $sel->start(); $sel->set_timeout("60000"); $sel->open("/home/index.jsp"); $sel->click("link=Log in"); $sel->wait_for_page_to_load("60000"); if ($sel->title_is("Entry")) { $sel->select_window("entry"); $sel->close(); $sel->select_window("null"); } else ($sel->title_is("Stealth")) { $sel->select_window("stealth"); $sel->close(); $sel->select_window("null"); } $sel->click("emailAddress"); $sel->type("emailAddress", "anon@anywhere.com"); $sel->click("password"); $sel->type("password", "password"); $sel->click("remember"); $sel->click("subButton"); $sel->wait_for_page_to_load("60000");
        icleave,
        Are you using the Selenium IDE FireFox plug-in to record your session and then modify it? Also, you are using Test::WWW::Selenium not WWW::Selenium. I think you want the latter not the former.

        I am not sure how to help you. Your code sample is fairly useless without the real website so that I can try it here to see what you are doing wrong. I am sorry, but unless you want to share the website and possibly login credentials, I can't guess what you are doing wrong.

        Update: As to your syntax errors - you should always use strict and use warnings. You have used else when you meant elsif. Also, you should either \@anywhere.com or you should use single quotes because it thinks your email address is really an array.

        Cheers - L~R
