Compressed JavaScript file is not working when running on Lucee 4.5 and Ubuntu 14.04 LTS Server

[Michael Aushana]

I have a CFML website that is using a compressed JavaScript function that seems to work fine on Windows 2008 and Railo community 3.0.3.003 final. But I try to use it on Ubuntu 14.04 LTS with Lucee 4.5.2.018 final it doesn't seem to work. Everything is working except this compressed JavaScript function. For some reason the compressed characters change and the function fails to work. I tried putting the code inline or in a js include file but they all don't seem to work. I'm not using any .htaccess files for this site. I look in the Lucee admin panel to see if there are any compression options that might be causing this but I can't seem to find anything. Has anyone seen this before? Any help is appreciated.

Thank you,

Mike

Point of clarification: when you say "compressed" are you talking about the web server gziping the file or do you mean something more along the lines of "condensed", where things like CRLF's are stripped out?

Hi Jordan,

Thank you for the reply. Sorry about the confusion. What I meant to say was the JavaScript is minified. I don't know what tool the previous dev used to minify the file with but I think it was one of the many online tools currently available. I'm not using any server side gzip or anything like that. Let me know if you have any other questions.

Thank you,

Mike

Hi Mike,

Ah yes "Minified". That is the proper term. I got it wrong too! lol

So, once again to clarify what you're saying, you're saying the minified JS file changes from the server to the client? That's extremely unusual. Are you using a standard Installer build with Apache as the web server? Or... maybe describe your setup a bit more...

Hi Jordan,

I'm running an Amazon micro AWS server with Ubuntu 14.04 64bit with Apache. I installed tomcat and Lucee using the Ubuntu Lucee installer. I have only 1 website running on this server with no other special configuration other than the UCanAccess jar files to work with the client's MS Access database. This website is currently running on another server which is a Windows 2008 with Railo 3.0.3 community and it runs fine with no issues. I'm just looking to upgrade and move the site as the current server is getting old. But on the Ubuntu server this particular cfm page fails because the minified javascript doesn't seem to be rendering properly as I'm getting errors saying that it can't find certain variables/objects etc. which are in this JavaScript. When I view the source of the rendered page in the browser and look at the inline minified JS code, it's showing some strange characters in FireFox and Chrome like black diamonds shapes, hearts etc. which is why I'm thinking its not rendering properly. I hope I given you enough info. Let me know if you have any other questions. Thanks again for your help.

Cheers,

Mike

Sounds like a character set issue. Maybe Railo/Tomcat and iis or Apache on your old server was configured to serve in utf-8 and your new server is not.

Reading utf-8 files in a character set other than utf-8 often results in seeing the black diamonds and question marks that you mention.

Here's what I'd do:


For a quick test .... Put the tag below in the cf[cm] file that reads and write the UK online JavaScript.

<cfprocessingdirective pageencoding="utf-8"/>

Check lucee web/server admin to see what default charset is in place.

Check the win 2008 server and verify the character encoding settings in Railo and Apache/IIS.

If you see differences, then change your settings on the new server to match the old server.

Check the character encoding of the file that contains the minified JavaScript. Many text editors will report the character encoding of open files.

Maybe it was utf-8 on the old server and somehow the encoding got changed when the files were copied to the new server. If that's the case you'll need to recopy the file taking care to maintain the same encoding.

Good luck!

Thanks Aaron. I will try that and report back.

Hi Aaron,

You were right. The character set was the issue. I checked my Railo installation and it was using windows-1252. I changed the values for Template and Resource charset to use windows-1252 in Lucee and now it's working. Thank you very much for all your help. Much appreciated.

Cheers,

Mike

No problem man. Fought my share of charset issues in the past and have more waiting for me in near future (mostly dealing with email parsing and template injection)

So it works fine in windows-1252 but not in utf-8 (I'm assuming the defaults in fresh installs of Ubuntu/Apache/tomcat/lucee would be utf-8)?

I was expecting you to say the opposite ... Tgat the old server was dishing out utf8 and the new setup had been configured to be windows-1252 or some other ANSI variant.

Even though you're back operational .... You should still make sure all of your charset settings are in alignment. It's common for them to be inconsistent. I suspect you have mismatched settings somewhere.

Places to check off the top of my head:

- the actual encoding of the files on disk
- the charset settings in the app server (lucee in this case)
- HTTP content-type headers injected by your webserver (Apache/iis/nginx) or servlet container (tomcat)
- any content-type meta tags in the HTML that your app sends to the browser to interept

The HTTP content-type header in Apache is important so that js/css and other text files that aren't handled by lucee get served in the right charset.

Hi Aaron,

Thanks again for the reply. When I was looking at the Lucee admin panel charset the defaults were I think ASCII or US-ASCII I can't remember now, for both of those options. I tried utf-8 but it didn't work. When I changed it to windows-1252 as per the old Railo server it started working fine. I will have a look at the places you listed and see if I can figure out where it might be causing this mix up. I would rather have it using utf-8 instead but I will see if that's possible. Thanks again for the great info, much appreciated.

Cheers,

Mike
