I've been looking at version 0.5.0 as I needed to make a change to reduce the amount of needless logging by EventFieldExtension.java.

To do this, I needed to get a working version on my current machine, using:
Netbeans 8.2
Maven 3.5.3
JDK 8.0.162
Tomcat 9.0.6
MySQL 5.7.17

This required updates to the pom.xml files plus a few lines of code. I've also amended the sample sql files to add indices to speed up queries. I've now got a compiled working version, and have created a pull request on GitHub.

Incidentally, I also tried updating all dependencies & plugins to the latest available version, but, although I could get everything to compile and run (with a few minor changes to code here & there), I could not actually access the webservice - I just kept getting "No services have been found". I imagine something's changed in the more recent versions of CXF that means earlier code no longer works correctly. I checked through all the annotations but could not see anything wrong.

(I also had another look at the epcis-webadapter, but am convinced the whole approach is fundamentally broken - the first thing it does on startup is attempt to download the entire database in order to generate a list of reader/business locations. If there was a standard EPCIS query to "get all locations" (which could then query the reader/bizloc tables directly) the webadapter could be re-written, but I don't think there is.)

Only one view of my post, and I think that was me... Do I assume this forum is dead, and Fosstrak too??!

Hi!

I am not sure about it.

In my case I am following the messages because I am working in EPCIS projects related to traceability in supply chain (not RFID).

Well, last commits to the project are 5+ years old and as you noticed yourself, technology is outdated. This project is in serious need of an update!

Your work is a great start to it! Would be great if you could share it on https://github.com/Fosstrak/fosstrak-epcis!

That said, I must admit that I haven't been working with the project or EPCIS at all since those 5+ years. And I guess I cannot help much with your current problem.
Do you have any error message in the log? Have you consulted the CXF Migration Guides (http://cxf.apache.org/docs/migration-guides.html)?

Best regards,
Marco

Indeed Marco:-)

However, three years or so ago it was moved from Googlecode to Github, due to the former closing down, so it would appear that, at least as recently as that, people were still interested in it.

And yes, I have added a Pull request on Github, which are the bare minimum changes required to get it to compile under JDK8. I'm not sure id anyone is monitoring the project though, and therefore whether anyone with appropriate authority is able to deal with it?

I have now managed to get Spring/Hibernate/CXF updated to versions 3.2.18.RELEASE/3.6.10.FINAL/2.2.12 respectively, but going beyond CXF 2.2.12 results in "No services have been found." when trying to access the web service. That's as far as I've got, still working on it. If my first pull request can be dealt with, I'll add another with the additional changes I've made so far.

Incidentally, I also looked at https://github.com/JaewookByun/epcis as an alternative, but it seemed to be a rather large overkill for the simple long-term demo I've been running (plus I would have to rebuild all my tables:-) ). Anyone else tried it and got comments?

Dave

Sorry, meant to add, yes I've looked at the migration guides. Specifically (as it seems to be where things are falling apart):
http://cxf.apache.org/docs/23-migration-guide.html

However, I couldn't see anything there to cause concern.

I have compared the logfiles I get when using CXF 2.2.12 and 2.3.0. The following differences seem to be significant:

These lines do not appear when using 2.2.12:
[org.springframework.beans.factory.xml.XmlBeanDefinitionReader:316] - Loading XML bean definitions from class path resource [META-INF/cxf/cxf-extension-http.xml]
[...]
[org.apache.cxf.bus.spring.BusWiringBeanFactoryPostProcessor:72] - Checking bean org.apache.cxf.service.factory.FactoryBeanListenerManager

[org.apache.cxf.bus.spring.BusWiringBeanFactoryPostProcessor:72] - Checking bean org.apache.cxf.transport.http.ClientOnlyHTTPTransportFactory

Later, these lines do not appear when using 2.3.0:
[org.apache.cxf.common.injection.ResourceInjector:191] - failed to resolve resource org.apache.cxf.bus.resource.ResourceManagerImpl/bus
[org.apache.cxf.resource.DefaultResourceManager:89] - resolving resource <org.apache.cxf.binding.BindingFactoryManagerImpl/bus> type <interface org.apache.cxf.Bus>

[org.apache.cxf.resource.DefaultResourceManager:89] - resolving resource <cxf> type <interface org.apache.cxf.Bus>

Later still, *both* files have:
(v2.2.12)
[org.apache.cxf.configuration.spring.ConfigurerImpl:158] - Could not find a definition for bean with id {http://query.repository.epcis.fosstrak.org/}QueryOperationsWebServicePort.jaxws-endpoint - no injection will be performed.
[org.apache.cxf.configuration.spring.ConfigurerImpl:158] - Could not find a definition for bean with id org.apache.cxf.jaxws.JaxWsServerFactoryBean - no injection will be performed.
[org.apache.cxf.service.factory.ReflectionServiceFactoryBean:399] - Creating Service {http://query.repository.epcis.fosstrak.org/}QueryOperationsWebServiceService from class org.fosstrak.epcis.soap.EPCISServicePortType

(v2.3.0)
[org.apache.cxf.configuration.spring.ConfigurerImpl:160] - Could not find a definition for bean with id {http://query.repository.epcis.fosstrak.org/}QueryOperationsWebServicePort.jaxws-endpoint - no injection will be performed.
[org.apache.cxf.configuration.spring.ConfigurerImpl:160] - Could not find a definition for bean with id org.apache.cxf.jaxws.JaxWsServerFactoryBean - no injection will be performed.
[org.apache.cxf.service.factory.ReflectionServiceFactoryBean:409] - Creating Service {http://query.repository.epcis.fosstrak.org/}QueryOperationsWebServiceService from class org.fosstrak.epcis.soap.EPCISServicePortType

(note change of line number, but same message)
So, according to that, no injection is happening, yet a service is being created. And I can access the service when using 2.2.12, but not 2.3.0...!!

Unless I'm really barking up the wrong tree...?

Dave

I've now created another pull request - I've added in the changes I've made to get spring/hibernate/cxf versions as high as I can.

I also started down the process of addressing some Java code recommendations (e.g. in Javadoc), though there is no functional change.
