Signavio Modeler does not start / Problems with Demo Setup

frauke

Hello everybody,

with Activity 5.0 the Modeler does not start. I am a Windows user with Firefox.
The Modeler displays a white page with the Tab-Title 'Explore|Signavio' and thats it.
I started the Tomcat using the demo setup.

Activiti Explorer and Activiti Probe start correctly, but I am not able to login using 'Kermit' as it used to be. I get the error message 'The system was unable to log you in.'

Does anybody have an idea to help me?

Looks like something went wrong when starting tomcat.

Can you check your catalina.out log for errors while starting spring-context in webapp-rest?

Hi,

I've got exactly the same problem.

The catalina log file does not show any exception.

Any ideas?

Thanks,

Hi,

It works however with Activiti 5.0 RC1…

Thanks,

I am using Windows and Firefox and mine does work.

I notice in the screen shot in the original post you are using port 8180. I'm using the default 8080, could it be a configuration issue related to that ?

frauke

No, its not a configuration problem of the port.
Then you would not get a Signavio titled page at all.
And with RC1 it worked - like Markus stated - and there I was using port 8180 too.

Thanks anyway for your hints!

Frauke

pault

Yes, very much a hint as I am new to the system.

But I did notice that there had been fixes/changes relating to URL handling and authentication (ACT 255 & 274). So just wondered if that might change the configuration requirements when switching from 8080.

Or might give some other clue.

Paul.

Maybe you should take a look at

activiti\apps\apache-tomcat-6.0.29\webapps\activiti-modeler\WEB-INF\classes\configuration.properties

I had to adjust that, when I started tomcat on a port other than 8080.

Hi all,

it has nothing to do with the port.

Doesn't work even on port 8080…

Hi all,

Has been resolved in Activiti 5.1. Thanks guys!

Hi everybody,

with my new Activiti 5.1 installation I still had the same problem.
But I finally managed to solve it:

The activiti-modeler-5.1.war was not unpacked completely by the demo setup and many files were just missing. After I unpacked it manually into the webapps directory, it worked.

Frauke

That's very strange, since the unpacking is done by just calling the ant 'unzip' action.
Do you happen to have a trace of running the bad demo setup?

frauke

I tried to reproduce it with tracing, but today it worked fine!
The unpacking of the activiti-modeler-5.1.war is done by Tomcat. I don't understand this either.

jbarrez

Let's blame cosmic radition on your hard disk … until we find out what really went wrong 😉

frauke

It MUST be that!
I am VERY experienced in deploying web applications with Tomcat, there can't be any other reason!

Hi all have the same Problem.
May be my description helps to solve it:

i use a mysql database,
on a ubuntu 10.10
with the activiti 5.1 version
After running ant demo.start the explorer.browser.start opens successive all the applications.
Also the modeler and its working.
But when i quit the browser and finish the ant script, the modeler is blank from now on.

Frauke can you please give a manual to your workaround ?

kind regards

frauke

1) Shutdown Tomcat

2) Find activiti-modeler.war.
It should be located it your Tomcat webapps directory, were the demo setup copied it to:
<Your Activiti Installation>\apps\apache-tomcat-6.0.29\webapps

3) Open the war file with WinZip (or any similar tool and) extract the content into the webapps\activiti-modeler directory of your Tomcat.

4) Confirm overwrite with 'yes to all' … or whatever

5) Restart Tomcat

thanks for the fast answer, but found something out.
I think its not the problem with the installation it has something to do with the url

if i use localhost its not working but when i use 127.0.0.1 its working fine.

also with manuel unpacked war arcive its not working with localhost.

tschernonoll

Found out that also the activiti explorer has problems here.
it seems there are some problems with the localhost url. if i use the loopback or direct ip adress it works fine also on an external server.

btw. i'm using a mysql db and phpmyadmin to access the db. may be the localhost problem comes from the second webserver ?

frauke

May be, but in my installation it really was the unpacking problem!
I've never had any problems with 'localhost' in the URL.
