Can you post the full path in which you unzipped the Activiti distro?

activiti-admin — Wed, 19 May 2010 05:23:04 GMT

/data2/Programs/Activiti

Mmm, the error could be cause because the logic expects that the unzipped folder name isnt changed (ie activiti-5.0.alpha1 or something similar)

Could you try that?

The problem is not in the folder name, rather the modeler .war was *somehow* not downloaded completely by the ant script, at least in my case, so the .war was corrupt. I did a manual download (http://activiti.org/downloads/activiti-modeler-5.0.alpha1.war) and now it seems to work properly after deploying it on tomcat.

BR,
Sasha

mmm, thanks for pointing that out. Interesting bug.

I'm wondering if we can do some checksum in ant after downloading the file.

indeed, the downloading could have some problem since I have also failed during downloading.
BUT I think that would NOT be the root cause of that exception.
let me guess:
1. maybe you did not use the build script(activiti-distro/setup/build.xml) to build your app
2. maybe you deployed the modeler.war directly into a tomcat web server which already exist.

jeff, I think you're right regarding that broken dl may not have been cause of that exception. I don't remember exactly which exception I got but I remember it was something related to zip not being able to process the arhive or similar. This is how I suspected that the .war had been corrupted.

Thanks for clarifying.

inside com.signavio.platform.core.impl.FsPlatformPropertiesImpl.<init>, it will try to match a group like".*activiti.*/apps/", so if you deploy the war directly into an existing tomcat web server, this match failed(if you run activiti-distro/setup/build.xml, the folder will be created).
I think this should be a bug, at least it does not have clear exception detail to tell me what happen but give me useless message "no match found", <java.lang.IllegalStateException: No match found> can be avoid if the author considered what matcher#find() returns

Good finding jeff. Wow, you're really into the source already !

Actually the activiti* matching is a fall-back mechanism.
If wou would declare a parameter 'fileSystemRootDirectory' in the web.xml, that one will be taken first before that fallback.

But you're right, we ought to document this.

Where exactly to put the 'fileSystemRootDirectory' parameter and which value ?
I am having the same problem (even I did the ant demo.setup and besides the modeler everything is working fine).

Hi,

Just open web.xml in [tomcat_dir]/webapps/[activiti_modeler_dir]/WEB-INF, and add this after all the other <context-param> elements:

<context-param>
<description>Filesystem directory that is used to store models</description>
<param-name>fileSystemRootDirectory</param-name><param-value>your_path</param-value>
</context-param>

…where your_path can be something like (in my case): /home/sebastian/activiti/apps/activiti-model-repository

Regards,
S.

This fix worked also for me although I wonder why this can't be automatic, maybe it already is but not working.

I tried it just now with a fresh alpha-3 and the only thing I changed was the build.properties to:
downloads.dir=../downloads (instead of ../../.. or whatever)

If this is working in alpha-4 just ignore me

Normally if you just unzip the zip file without changing any folder name, it works automatically by searching for the activiti unzipped root folder.

I just tried it with alpha 3 here on a fresh windows and all seems to work. Could you explain which steps you've taken to try it ?

Re: modeler app don't start

neothemachine — Thu, 29 Jul 2010 16:47:30 GMT

I know where the fault is.

I unpacked the zip file to a folder named "Activiti" and the regex is searching for "activiti" -> case!!!

So..that's the problem. Could this be solved another way without the hacky regex and without setting this fileSystemRootDirectory parameter manually?
