Running Mojoportal under Ubuntu 11.04 is proving a real challenge. Working with the with the mojoportal 2-3-7-0 download files for NET3.5  and a MySQL database, I have finally managed to install Monodevelop, Apache2, xsp2, xsp4 and mono-server, and after inserting many configuration settings, simple testpage .aspx files are working.

However when trying to access the /Setup/Default.aspx page in Apache an error is shown 

Service Temporarily Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Apache/2.2.17 (Ubuntu) Server at 127.0.0.2 Port 80

If I manually start XSP2 or XSP4  and declare the root as /var/www/essexbp.com [which is the name I have used throughout all files and settings for the webserver] I get this error

xsp4 --root /var/www/essexbp.com
Exception during TraceManager initialization:
System.Xml.XmlException: a name did not start with a legal character 45 (-)  Line 67, position 2.

Followed by many lines of errors with mono-server named and xml named over and over

If I use /var/www/essexbp.com/Setup as the root I get  no errors but then using port 8080 to open /Setup/Default.aspx I get this error

Server Error in '/' Application

Parser Error

Version information: Mono Runtime Version: 2.10.5 (Debian 2.10.5-1~dhx1~lucid1); ASP.NET Version: 4.0.30319.1

Does this identify any cause of the problem?

Running Mojoportal under Ubuntu is certainly not easy, although there are help pages on the internet where people claim to have succeeded, but none of their instructions have yet worked for me. Or is it simply that it is not possible to use Mojoportal under Ubuntu?

Many thanks for that tip Joe, I wish I could report success, but I am afraid that I am getting the same errors. I don't really know enough about working with apache, virtual hosts and content management systems to be able to tell if I am doing things correctly or making mistakes. I had hoped that a step by step approach would eventually work but it hasn't and I cannot tell what I am doing wrong. It's all way over my head, so I had better stop before I spend even more time on fruitless trial and error.

Many thanks

The source code is compiled into dlls in the bin folder so you won't find it on disk using the pre-compiled release packages of mojoPortal.

Unfortunately there are often bugs in Mono, it has never become stable enough for me to recommend it for any production web site and lately I have not been testing it at all. It is always hit or miss, often it work but there are some bugs but new releases of Mono often break things, some bugs get fixed, some new ones appear, some regressions occur. It has been that way since 2004, every now and then it works reasonably well but with a few minor bugs but often there are major bugs. Sometimes it doesn't work at all, sometimes it works under xsp2 but not under mod_mono.

I haven't given up on Mono completely though, at some point I plan to start testing again but I'm not setup to do it at the moment. They used to release VMWare images of Mono on openSuse and that made it easier for me to setup a testing environment but since Mono is no longer under Novell they no longer make a VM available so it is more work to setup a testing environment.

Sorry that I don't have better news for you.

Best,

Joe

It's a shame for mono and linux to lose to MS 

I agree except it never really got all the way there, its always been almost there as far as ASP.NET on Mono/Linux. But of course ASP.NET keeps evolving too and is a moving target for the Mono team to try and keep up with it. Mono still has many great uses, its just that it never quite got all the way there as far as becoming a stable reliable environment for ASP.NET. In my opinion the problem is not enough eating your own dogfood. The Mono site has never run on ASP.NET and when Mono was under Novell none of their sites used it, they always used wikiemedia or other PHP things. If they used it for large important sites that matter to them then they would find the bugs and it would have become stable but instead they just throw it out there for others to use and hope they get good bug reports with test cases.

Best,

Joe

I am also having problem with mojoportal 2.3.6.5 for mono and postgresql:

but with that said, if you (Mr. Audette) need a Linux virtual machine configured with asp.net, I can build one and host it on my web server with any Linux distribution.
