Hello, I am trying to follow the Fosstrak User Guide and all seems well until step 6 of Configuring the Repository. It says "In a default installation of Tomcat, the database connection settings can be found in $TOMCAT_HOME/conf/Catalina/localhost/epcis-repository-<version>.xml". I cannot find this file anywhere. My version is 0.5.0. Can someone help? Thanks, Luis.

Hi Luis,

I had a huge amount of trouble following the instructions at
http://fosstrak.github.io/epcis/docs/user-guide.html .

If you do what it says and create the file ..\apache-tomcat\conf\Catalina\localhost\epcis-repository-0.5.0.xml with the suggested contents, IT DOES NOT WORK!

Instead, the file it seems to use is at ..\apache-tomcat\webapps\epcis-repository-0.5.0\META-INF\context.xml.

Then again, I went with defaults all the way through so didn't have to change anything!

Regards,
Dave

Hey, Dave, thanks a lot. It was there indeed. I got the capture screen fine, but the query did not show a wsdl, it returned the text below. Do you have another hint? Thanks a lot again for your time. 

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>
No such operation: epcis-repository-0.5.0null (HTTP GET PATH_INFO: /epcis-repository-0.5.0null)
</faultstring>
</soap:Fault>
</soap:Body>
</soap:Envelope>

Hi Luis,

What link did you try to follow?

If you've got it set up correctly, in your browser you should be able to go to:

http://<webserver>/epcis-repository-0.5.0/

and get a page that looks like:

Fosstrak
Fosstrak EPCIS Capture and Query Services
This is the Fosstrak EPCIS Web application providing the following two services

    Fosstrak EPCIS Capture interface (HTTP POST)
    Fosstrak EPCIS Query interface (Web service, WSDL)

Then if you click on the Capture link ( http://<webserver>/epcis-repository-0.5.0/capture ) you get:

Fosstrak
Fosstrak EPCIS Capture Service
This service captures EPCIS events sent to it using HTTP POST requests.
The payload of the HTTP POST request is expected to be an XML document conforming to the EPCISDocument schema.

For further information refer to the xml schema files, check the Example
in 'EPC Information Services (EPCIS) Version 1.0 Specification', Section 9.6,
or see the Fosstrak EPCIS user guide.

» show HTML capture form

Or, if you click on the Query link ( http://<webserver>/epcis-repository-0.5.0/query/services ) you get:

Available SOAP services:
EPCISServicePortType

    getStandardVersion
    getQueryNames
    getVendorVersion
    subscribe
    unsubscribe
    getSubscriptionIDs
    poll

    Endpoint address: http://localhost:8080/epcis-repository-0.5.0/query/
WSDL : {http://query.repository.epcis.fosstrak.org/}QueryOperationsWebServiceService
Target namespace: http://query.repository.epcis.fosstrak.org/

Or, if you click on the WSDL link ( http://<webserver>/epcis-repository-0.5.0/query/?wsdl ) you get:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
      <wsdl:definitions name="QueryOperationsWebServiceService" targetNamespace="http://query.repository.epcis.fosstrak.org/">
[...]
</wsdl:definitions>

(I've removed all formatting!)

Regards,
Dave

In the user manual it does not say query/services, only query. I got it and it is working fine. 
User Manual text: 

In a default installation of Tomcat, the capture and query interfaces will now be available at http://localhost:8080/epcis-repository-<version>/capture and http://localhost:8080/epcis-repository-<version>/query, respectively.

Again, thank you very much.

So it does - and when I do that I get the same error as you did - I'd never noticed that before!

I guess I must have always clicked on the link from http://localhost:8080/epcis-repository-<version> when testing my installation, rather than following the manual at that point.

I must say, I tend not to use my browser  now for it - I use wget to send xml files to the capture interface, and SOAPUI or Excel macros to query the data.

I did try to work with the web-adapter, also listed on the Fosstrak site, but to be honest it's not very well written and would take far too long to rewrite. (For instance, it seems that one of the first things it does on start up is try to query the *entire* epcis repository - and if there's more than a few hundred records it soon times out and crashes.)

Regards,
Dave

Thanks a lot, Dave, but let me tell you something, I am an university professor here in Rio de Janeiro and I am just trying to enrich my Information Management course. It is the first time I am looking at this and you seem to be very experienced in the subject. I am just trying to follow the manual before I tell my students to do that. But maybe you can help me a little more. In the EPCIS capture interface client (screen attached) I filled an example (screen attached)  comes the error screen (attached).

Olá Luiz,

Não entendo muito do fosstrak porém posso falar sobre o EPCIS.

Acho que a forma mais didática para que você consiga entender e identificar o problema, é usando outra ferramenta que não o cliente do fosstrack. Como a interface de CAPTURE é um http normal, você pode simular isso usando o SOAPUI ou o POSTMAN.

A unica ressalva é que você deverá escrever (ou pegar exemplos) os eventos EPCIS para enviar.

Eu não sei se você notou mas a sua URL está apontando para http://demo.fosstrak.org/epcis/capture quando na verdade deveria ser o endereço da SUA instalação do fosstrack.

Talvez seja isso.

Abs

Hi Luis,

I expect your problem is indeed because you're pointing the client at http://demo.fosstrak.org/EPCIS/capture .

You need to use http://<webserver>/epcis-repository-0.5.0/capture (i.e. whatever you set the webserver up as, whatever link you saw when you went to http://<webserver>/epcis-
repository-0.5.0 in your web browser).

As others have said, I started with the capture client, but then switched to SOAPUI for testing (it reads the wsdl & creates test xml for you, you just have to fill in the details). I now create xml files using a php script and use wget to send them to the repository - all automated, no GUI at all:-)

Regards,
Dave

Valeu, Rodrigo, obrigado. Mas no User Guide está:

  1. In the GUI, you need to specify the URL of the EPCIS repository you want to connect to. You can either use your local repository instance (e.g., http://localhost:8080/epcis-repository-<version>/capture>), our public repository (http://demo.fosstrak.org/epcis/capture), or any other EPCIS repository. You can now fill in the EPCIS event data and submit the EPCIS capture request by clicking "Generate event".
Por isso tentei usar o público. Agora deu certo. 
Mas como você disse que era mais fácil usar o SOAPUI, eu baixei e instalei o 5.2.1. Mas estou achando muito complicado. Existe algum tutorial mais simples do que aqueles que vem junto com o produto? 

Obrigado.

Luis,

Você está achando complicado usar o SOAPUI ou gerar os eventos?

Imagine que o SOAP UI é só o meio para você mandar a request http. Se o problema for o uso do SOAPUI, você pode tentar usar o postman, que é um plugin do chrome.


Se a dificuldade for em gerar os eventos, ai acho que você seguir o manual do EPCIS. 

O seu objetivo é usar o repositório para qual tipo de produto?

Já são serializados ou vai rastrear por lote? 

Abraços.

Obrigado, Rodrigo, eu sou professor da UFRJ aqui no Rio e cheguei ao EPCIS na tentativa de introduzir este assunto no meu curso de Gerência da Informação, que aborda o EPC. O que você puder me indicar será bem vindo.

Luis,

 

Tente com o POSTMAN

Ele é mais simples que o SOAPUI.

Abraços.

Hi Luis,

I have to agree, SOAPUI isn't easy to use at first sight!

As I said, I use it for querying the EPCIS repository, rather than capturing events, so I'll describe what works for me for queries (from my memory - once it's set up you don't have to repeat much of this!).

(1) In the left-hand pane, right-click Projects - New SOAP Project
(2) Project Name = whatever you want
(3) Initial WSDL = http://<webserver>/epcis-repository-0.5.0/query/?wsdl
(4) Check that "Create Requests" is ticked, and click OK
(5) Right-click your new project - New TestSuite
(6) Right-click your new TestSuite - New TestCase
(7) Right-click your new TestCase - Add Step - SOAP Request
(8) Enter any name for the new step & click OK
(9) In the new box that appears, scroll down to QueryOperationsWebServiceServiceSoapBinding -> poll & click OK
(10) Enter any name for the new request & click OK

You should end up with something that looks like:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:epcglobal:epcis-query:xsd:1">
   <soapenv:Header/>
   <soapenv:Body>
      <urn:Poll>
         <queryName>?</queryName>
         <params/>
      </urn:Poll>
   </soapenv:Body>
</soapenv:Envelope>

And in the text box above the window it should point at your web service ( http://<webserver>/epcis-repository-0.5.0/query/ )

Now you just(!) need to fill in (valid) query parameters - and that does need a bit of learning as well. I used & amended examples from the GS1 EPCIS in rail application standard ( http://www.gs1.org/sites/default/files/docs/epc/GS1_EPCIS_Rail_Standard.pdf ), as that was the area in which I was interested.

For instance, one of my sample queries looks like this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:epcglobal:epcis-query:xsd:1">
  <soapenv:Header/>
  <soapenv:Body>
    <urn:Poll>
        <queryName>SimpleEventQuery</queryName>
        <params>
          <param>
            <name>EQ_action</name>
            <value xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="urn:ArrayOfString">
              <string>ADD</string>
            </value>
          </param>
          <param>
            <name>GE_eventTime</name>
            <value xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:dateTime">2014-07-13T00:00:00.000Z</value>
          </param>
          <param>
            <name>LT_eventTime</name>
            <value xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:dateTime">2014-07-13T23:59:59.999Z</value>
          </param>
          <param>
            <name>WD_bizLocation</name>
            <value xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="urn:ArrayOfString">
              <string>urn:epc:id:sgln:{a location}</string>
            </value>
          </param>
        </params>
    </urn:Poll>
  </soapenv:Body>
</soapenv:Envelope>

This returns all Transactions performed at {a location} between 2014-07-13T00:00:00.000Z and 2014-07-13T23:59:59.999Z as xml data.

Hope this is a useful starter!
Regards,
Dave
