jsf config error - MOZILLA_FIVE_HOME

[lineker]

Hello,

I am new to jsf.
I want to open a project.
Here are my steps

1-) File->New->Dynamic Web Project
2-) At opened form I select Configuration: JavaServer Faces v2.2 Project
3-) I click on Next button 2 times and reached to form Jsf Capabilities
4-) At articles, it says me to click on download button at the right of 1st textbox. Download starts but I got followğng error:

Unhandled event loop exception
No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]

I searched google and found an offer to set following

export MOZILLA_FIVE_HOME=/usr/lib/mozilla

I did it, restarted eclipse but same error exists!

The JSF bit is a red herring though, this is not related to JSF at all. It seems to be an Eclipse under Linux specific issue to do with an internal browser the IDE uses (probably for doing previews of web projects). I would rather try the Eclipse forums for suggestions and tech support.

My first hit when I google the error:

https://groups.google.com/forum/#!to...nd/5SjPTy0MmEo

Suggests to install libwebkitgtk. How will probably depend on what distribution you have.

Dear gimbal2,

After writing my thread I searched from google and downloaded libwebkitgtk.
Now I am not getting error at 4th stepped I wrote at my 1st thread.
But now my project is not opened.
I check

Window -> Web Browser

I see 3 options:


0 Internal Web Browser
1 Default system web browser
2 Firefox

0 Internal Web Browser is selected

Tomcat is started, I wrote a simple code 'Hello World' with file name HelloWord.jsp.
When I select 'Publish' from Tomcat nothing is displayed.

I am writing 'http://localhost' to browser and see :

It works!

This is the default web page for this server.

The web server software is running but no content has been added, yet.

I am writing 'http://localhost:8080' to browser and see :

HTTP Status 404 - /

type Status report

I am writing 'http://localhost:8080/demo4/HelloWorld.jsp' to browser and see :

Okay, the problem was solved. Good luck figuring out your latest problem. If after investing enough personal time into it you still can't figure it out, feel free to come back and ask for help. I would start by finding the HelloWorld_jsp.java file that the stacktrace is pointing you to and looking what is on line 97 to figure out what might be causing the crash.

I would also advise you to upgrade to a more recent version of Tomcat, your version is way too old and dozens of bugs have been fixed since then.

Hi gimbal2,

Thanks for support. I will only ask 1 simple question.
Although I downloaded tomcat 7.0.50 I see 7.0.12.
how can it be?I added 2 pictures.

[lineker]

I am sending 1 more picture.

Althugh I select 7.0.50 folder, I see 7.0.12 and bottom right which is the issue I can not explain

[gimbal2]

Because you did something wrong. I can't say what, I don't know what you did. It looks like you managed to install a Tomcat 7.0.12 in a directory named 7.0.50.
