I'm running EPCIS repository 0.5.0 on Tomcat 7 on Debian. In my logs I see

  The last packet successfully received from the server was 34,303,076 milliseconds ago.  The last packet sent successfully to the server was 1 milliseconds ago.
  com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

At this point I just restart the Tomcat server and the connection to the MySQL 
server is restored. I understand that the problem is that I use the server to 
seldom ... I think a possible solution is suggested at

Hi,

I think that during the transfer to Google Code you forgot to upload the 
hal-simulator used in AleCapturingApp QuickStart Guide 
(http://code.google.com/p/fosstrak/wiki/AleCapturingAppQuickStart) or if i'm 
wrong could you tell me where I can find it?

Thanks

Yuri

tests performed with the Impinj reader revolution R220, using the middleware 
fosstrak. 

In LLRP-COMMANDER I send a ROSPEC_example.llrp and get a valid response.

The problem starts when I read more than one tag, because it writes the EPCIS 
database only one tag and ignores the others.
tags remaining are recorded only when I run a DISABLE_ROSPEC and ENABLE_ROSPEC.

I wonder if the configuration can be ROSPEC_example.llrp.

How many tags can read and write to the EPCIS database, because the way I 
tested it writes only one tag and ignores the others.

Below is the configuration of the ROSPEC_example.llrp

http://pastebin.com/x3SANZym

Steps:
1. Connect to Reader
2. Add new ROSpec
3. Add new ACCESSSpec with AccessCommand having below value
<llrp:C1G2TargetTag>
<llrp:MB>1</llrp:MB>
<llrp:Match>1</llrp:Match>
<llrp:Pointer>0</llrp:Pointer>
<llrp:TagMask>111111111111111111111111</llrp:TagMask>
<llrp:TagData>111111111111111111111111</llrp:TagData>
</llrp:C1G2TargetTag>

4. now create a tag with epc value "111111111111111111111111" on llrp reader in 
reader Emulator(I m using Rifidi Emulator) 

expected output:

C1G2Read/C1GeWrite should be perform on tag with id "111111111111111111111111"


Actual output:
not able to match the EPC values

version:1.1.0
OS: windows XP

steps reproduce the problem:
1. create an ECSpec
2. register multiple EventSinks
3. only one sink is receiving notifications

The issue is present since the integration of the persistence API.

I receive "EXCEPTION_UNKOWN" llrp message from my server adaptorfor readers 
which are configured as readerInitiated.
My readers are correctly configured to send messages to my server.

What could be the cause of this exception message?

Thanks

regards

I`ve tried take copy of source via TortoiseSVN, but he said 
"URL http://fosstrak.googlecode.com/svn/trunk/ doesn`t exists". 

I added a filterSpec to filter on epc tags to filter on company prefix but it 
doesn't work. No tag was reported in the EcReports!


It seems that the pure identity format is used to set the "TagIDAsPureURI" in 
the objet "Tag" in LLRPAdaptor.java.
It leads to use a tag with format "urn:epc:id:sgtin" while the pattern used in 
the filterSpec is "urn:epc:pat:sgtin-96".
So you must use the method "convert_to_TAG_ENCODING" instead of 
"convert_to_PURE_IDENTITY" to set the tag ID.

Regards.

What steps will reproduce the problem?
1. Build project with maven

What is the expected output? What do you see instead?
The maven repo http://maven-repository.fosstrak.org/releases seems not reachable

What version of the product are you using? On what operating system?
I am using maven 2 in windows 7

Which version of LLRP was implemented while developping FC module?

What steps will reproduce the problem?
1. Deploy fc-server-1.10 (tomcat 7, but i think os not relevant)


What is the expected output? What do you see instead?

The war shoulld be deployed and be in status running.
Instead an exception is thrown:

Please provide any additional information below.

I think that the problem might be a wrong package reference in:

fc-1.1.0/ fc-server/ src/ main/ java/ org/ fosstrak/ ale/ server/ llrp/ 
LLRPControllerImpl.java

At line 14:

WebService(endpointInterface = 
"com.orange.api.rfid.ale.server.llrp.LLRPController")

I have a system with at most 2 imping speedway 220 readers.

The scenario is the following:
1. reader 1 reads tags and all is OK
2. reader 2 reads other tags and tags are managed by event cycle of reader 1 !! 

Our expected behaviour is that each reader is working independantly and it is 
working like if there would have only one reader !!


I am sure that reader 1 can not read tags readen by reader 2.

Thanks in advance.

Hi, 

I just installed the LLRP commander plugin, and added an hardware reader in it. 
When trying to send a simple "GET_READER_CAPABILITIES" message to my reader, I 
get this error : 

org.apache.mina.filter.codec.protocoldecoderexception

I'm using the latest version of LLRP commander, and my OS is Fedora 18.

Thank you for your answer, Matthieu

Hi,
I've setup WebAdapter-0.1.0 on my Windows7 machine as explained in the user 
guide. Its working fine, however when I tried to query both Object and 
Aggregation events, it seems it only returns the result based on first event 
only. i.e it only returns data for either Object event or Aggregation based on 
their sequence.

For example the below query should return the result for both Object as well as 
Aggregation events however it returns only object events. 

epcis-webadapter-0.1.0/rest/1/eventquery/result?time=&recordtime=&type=ObjectEve
nt&type=AggregationEvent&step=&disposition=&reader=&readerdescendant=&location=&
locationdescendant=&transaction=&epc=&parentid=&anyepc=&epcclass=&quantity=&orde
r=&ordering=&eventlimit=&maxeventlimit=


However if i run the query with type sequence changed i.e

epcis-webadapter-0.1.0/rest/1/eventquery/result?time=&recordtime=&type=Aggregati
onEvent&type=ObjectEvent&step=&disposition=&reader=&readerdescendant=&location=&
locationdescendant=&transaction=&epc=&parentid=&anyepc=&epcclass=&quantity=&orde
r=&ordering=&eventlimit=&maxeventlimit=

it returns the result only for Aggregation events.


Please suggest if i am doing any thing wrong.

Thanks & Regards,
Ravindra
