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?

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.

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.

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! :lol:

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

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.
