Re: Upgraded to Roller 6.1.1

2023-01-05T20:22:42+00:00

Hi, I think Roller is a great blogg-framework, but not without snags unfortunately. I recently upgraded from 5.x to the 6.1.1 and for some reason my images dissapeared totally. I also used the "Gaurav" theme which does not look like being supported any longer with the 6.1.1 release. I stumbled across a bunch of themes the other day (https://code.google.com/archive/a/apache-extras.org/p/roller-extras) and tried to follow the instructions but neither of them shows up in the drop-down meny in the designer mode. Is there some trick to make them work?

Thank you for reposting this information. Your work was an important stepping stone in my own professional development along the way to understanding RSS. I would like to admit however, that I'm running my current blog using the Jekyll static content generator (which in turn uses Ruby). Hosting static content is an economical and secure alternative. It's still pleasant to see what a dynamic solution can offer!

Excellent tool

Re: Roller 6 released

Hi Renato, Yes, that is a problem for Roller. There are very few themes and most of them were designed at least 10 years ago. Dave

Re: Roller 6 released

2021-05-02T15:04:49+00:00

Hello Dave, I'm trying Roller 6.0.1 on local virtual machines and it's great so far. The only thing I would complain about are the default themes: they don't seem to be "modern" enough. Is there somewhere a collection of decent pre-made themes? Sorry for the question, I don't have enough time to make a theme on my own. Thanks.

Re: Powered by Digital Ocean Kubernetes

2020-06-25T22:47:29+00:00

I'm very interested in the container version of Jroller using Digital Ocean Kubernetes. Is there a write up in more detail? Is there some subversion checkout to play with.. I'm assuming you build this stuff from source to deploy? I'd like to do the same for a blog about MakerFare, Ham Radio & Kit building under my domain CutterElectronics.com. I'm thinking instead of postgres, to use something like mongodb with a SQL interface layer .. to make it look like postgres SQL. Thanks for any updates, - Tom

Re: Doesn't anybody have anything bad to say about Groovy?

2019-05-23T16:51:39+00:00

I DESPISE Groovy. I got suck with making corrections to old application and this is a nightmare. Why would any rational person drop into this language with miserable poor documentation and support? Even Stack Overflow has almost no support for issues. Simple to write from scratch? Disaster to debug.Look, you might be "having fun" playing with tinker toys too but you cannot build a house with it. This application is very small but builds into a 75meg war file. That is terrible to deliver. Simply put run screaming from this thing while you can. Move to Angular at least you will get something with a future. We will rewrite this application eventually when the pain of supporting this one off pile of garbage gets too extreme.

Re: Powered by Postgresql and Docker Swarm

2018-03-13T14:59:07+00:00

Anant,

No specific issue with MySQL.

I had some inexplicable problems running MySQL under Docker and switched to PostgreSQL in hopes of solving those problems. The change did not really help. I suspect there was some problem in Digital Ocean networking that was causing problems in Docker Swarm. Those problems eventually went away.

Nope, I did not setup Apache or Ngnix. Just Tomcat on port 80.

Re: Powered by Postgresql and Docker Swarm

Any particular issue, you find with mysql ?I think postgresql consume more RAM compare to mysql.

Thanks.

Re: Now hosted on DigitalOcean

Hi Glen, I'm still happy with DO and still using the $10 plan and just one Droplet, which seems to work fine for my (extremely low :-) level of traffic. I'm using 64-bit Ubuntu. - Dave

Re: Now hosted on DigitalOcean

2016-07-02T21:52:17+00:00

Hi Dave, I'm thinking of switching my blog's hosting provider and have a few questions about Digital Ocean: (1) are you still happy with DO, (2) was it just one droplet necessary to host both the database and ubuntu/Tomcat? (3) through one year, has the $10 plan held up or you found you needed to upgrade to the $20 plan for performance to be acceptable? (4) What server did you choose -- 32bit or 64bit ubuntu or? Thanks! Glen

Re: Doesn't anybody have anything bad to say about Groovy?

2016-03-29T20:18:43+00:00

It does not have compile time checking, so some idiot error is not caught until runtime. Sure they added a static compile annotation, but at that point why not just use Java. Groovy programmers are not disciplined, so they write sloppy code that looks like VB 6, and Groovy lets them get away from it. It is 2016, and Groovy is still dog slow when compared to Java. Pivotal dropped Groovy, so who is their sponsor now? Not going to bank a corporate information system on some toy project with no corporate sponsors and then find out the devs have given up to focus on "Real Life (TM)" -> which happens to be the lamest excuse to stop supporting a project.

Re: Now hosted on DigitalOcean

2016-03-04T12:50:47+00:00

Thanks Amit, that's nice tip. I don't think manual installation will cause any performance problems.

Re: Now hosted on DigitalOcean

2016-02-29T07:42:29+00:00

There is also one click install app for roller weblog

https://bitnami.com/stack/roller

(just sign in to bitnami, go to launchpad, and install the roller weblog on digital ocean droplet.)

It is easy then manually installation of roller blog on digital ocean,specially new bee like me.

However I don't know , whether it will make performance issue over manual installation or not?

Hi Ganesh,

Thanks for the feedback. I just tried to run the VagrantFile on a different computer and it failed to install.

I'll update this issue once I figure out what is wrong:

Thank you for the work you have done. I followed the mentioned steps and bring up the application but the authentication fails for superuser and password test.

Re: How to create a Roller 4.0 theme, part 1

Hi Ron, this is a custom theme and I haven't (yet) made it available outside of my blog site.

Re: How to create a Roller 4.0 theme, part 1

I like your theme! Is this theme available to anyone, or is it your own custom theme?

Re: New Bootstrap based theme

2014-01-21T19:13:57+00:00

Thanks Pat. I'll trim down that header images because you're right, nobody is going to see the whole thing. That Expires:0 thing must be a Roller bug.

Re: New Bootstrap based theme

2014-01-21T02:59:17+00:00

It appears all your images are coming down with Expires: 0 on them, so they will always be reloaded. In addition, the banner image is 2483x420 and 1.7MB. Should resize that to 1000px wide, and you can prolly apply some JPEG compression. Also, it appears the image is clipped anyway, so almost no one is going to see those red leaves on the far right.

The code from the old Java.net "Roller Support" project is now part of the "Roller Extras" project on Google Code. That's where you can find the source for the Roller Memcache plugin there: http://bit.ly/WFO46q

In my knowledge roller is best blogware. I had used roller 3.1 with struts 1.x and roller 4.x with struts 2.x in 2007-2008. I have learned a lot from this blogware.

Re: 10 years ago today

2012-05-08T17:47:10+00:00

A 10 year long Time well spent I must say. This kind of product matters larger than any tangible benefit you could get.

Just stopped by to say thanks for all your work you have done so far to make this great.

That's great Dave. So what's happening with SocialSite now after 3 years ? Is it still in progress ?

Re: The X-rated SocialSite API

2012-04-26T16:45:35+00:00

Roy Fielding's post is a dictatorial rant showing himself to be petty and egotistical. REST is a great idea, but he should not at all be surprised that many would prefer to cherry pick on his enshrined constraints than wade through pedantic white papers.

There are a lot of broken manuals out there, by his own admission, and he's going to have to accept that his academic dissertation has turned into a buzz word. Just call your API Rest-like, and ignore Fielding.

Re: 10 years ago today

2012-04-17T20:21:53+00:00

After 2000+ entries on Roller I think I can claim that this is one of the very rare software that has never let me down.

Kudos Dave for all the work and energy you've put into this!

Hi Guys,

I am using a web server and have DNS restrictions for context mapping.

Can we modify <servlet-mapping><url-pattern>

original:
<servlet-mapping>
<servlet-name>js</servlet-name>
<url-pattern>/gadgets/js/*</url-pattern>
</servlet-mapping>

what I need is:
<servlet-mapping>
<servlet-name>js</servlet-name>
<url-pattern>/app/gadgets/js/*</url-pattern>
</servlet-mapping>

I tried doing this and it shows me Js Uri path invalid, expected prefix: /gadgets/js, is: /app/gadgets/js/shindig-container:rpc.js

Any help on this? With this I can call the shindig js.

Thanks in advance

It might be possible to integrate Roller with 5.0, but I have never tested it. Your best change of getting an answer is on the Roller mailing lists.
