[Fiware-tech-help] CEP GE: error running sample

[Pedro Alves]

Hi,

I installed the CEP GE - IBM Proactive Technology Online following the
instructions found in the
CEP GE - IBM Proactive Technology Online Installation and Administration
Guide [1].

I was able to successfully deploy the application to Tomcat. But I had a
problem running the sample, referred in section "Sanity check procedures
End to End Testing" [2]:
 I extracted the sample directory (sample.zip) found inside the zip file
IBMProtonOnWebServer.zip (downloaded from the repository [3]) to the root
directory of Tomcat.
When starting Tomcat I can see a warning:
"WARNING: initializeAdapters: failed to initialize adapter Input adapter
for producer: P1, reason: ./config/input-for-dosAttack.txt (No such file or
directory)".
The file "./config/input-for-dosAttack.txt" is defined in the file
./webapps/ProtonOnWebServer/DoSAttack2.json. The JSON file is read by the
application ProtonOnWebServer due to being configured, by default, in the
./webapps/ProtonOnWebServer/Proton.properties file, with "metadataFileName
 = DoSAttack2.json".
To successfully run the sample when deploying the Proton war file I need to
create a directory named "config" in the root directory of Tomcat and copy
the file input-for-dosAttack.txt from ./webapps/ProtonOnWebServer/ to this
new folder. Or alternatively, change "./config/input-for-dosAttack.txt" to
"./webapps/ProtonOnWebServer/input-for-dosAttack.txt" in the file
./webapps/ProtonOnWebServer/DoSAttack2.json.

There are other issues related with loading the samples.

The DoSAttack_SteepDemand.txt is not generated, as described in [2], when
running the samples (after the changes referred above). Instead, is
generated a file named DoSAttack_PredictedCrash.txt.

According to [2], a file named DoSAttack.json, located in the sample
folder contains paths for the input event file and for the output files.
Actually the file loaded with the sample is the
file ./webapps/ProtonOnWebServer/DoSAttack2.json.

In [2] is written"If you run on linux, you should change the 3 relative
paths in this file to ".\/sample\/" instead of "../sample/"", but all the
JSON files have Linux path, so is the opposite, it is the Windows users
that need to change the path instead of the Linux ones.

There are several JSON files with Proton definition spread over different
locations that may confuse someone who is testing the app. Like:
./webapps/AuthoringToolWebServer/SavedProjects/ (3 files showed in the Open
Project drop menu in [4])
./webapps/ProtonOnWebServer/DoSAttack2.json (definition file loaded when
deploying the app)
Additionally there are the JSON files included in the samples folder. These
definition files found in the sample folder can be imported and loaded from
the "Import project..." menu in [4]. These sample files do not run just by
copying the sample folder to Tomcat root directory, as described in [2].

Testing setup:
OS: Linux OpenSUSE 13.1
Tomcat: 7.0.26
Browser: Google Chrome
