Latest Release: 0.10.8
The TOOP Infrastructure Simulator provides a platform that mimics the workflow of the entire TOOP Infrastructure in a local or online environment. Its purpose is to assist DC and DP instances for testing their systems during development, prior to joining a production environment.
- Download the jar bundle from https://repo1.maven.org/maven2/eu/toop/toop-simulator/0.10.8/toop-simulator-0.10.8-bundle.jar
- run it as
java -jar toop-simulator-0.10.8-bundle.jar. This will start the simulator in [DP mode](#Simulation Modes) (i.e. it will simulate the toop-connector as well as a DP). [More on simulator modes](#Simulation Modes) - The simulator will start http servers on ports 8081 and 8082 for the connector and DP respectively.
It will assume the existence of and use a
/to-dcendpoint (i.e. DC) onhttp://localhost:8080/to-dc. - Now you can,
- start up your own DC on localhost:8080
- send requests to the simulator on port
http://localhost:8081/from-dc - and receive responses or errors on port
http://localhost:8080/to-dc
Toop simulator supports three working modes; namely DC, SOLE and DP (default).
A toop-commander which is activated only
in DC and DP modes is also bundled inside.
- As JVM ARG: -DSIM_MODE=DC
- As ENV variable: export SIM_MODE=DC
- via toop-simulator.conf: toop-simulator.mode="DC"
In DC mode, toop-simulator launches a toop-commander which provides a command line
interface and a DC endpoint connected directly to the simulator. In DC mode,
you may provide a URL for an external DP via the DP_URL to communicate with.
The DP_URL variable can be omitted, in which case the default DP url
(http://localhost:8082/to-dp) will be used.
The architecture view for the DC mode is given below.
To launch the simulator in DC mode, run the following command
# using JVM ARGS
java -DSIM_MODE=DC -DDP_URL="http://some.dp/to-dp" -jar toop-simulator-0.10.8-bundle.jar
# or alternatively set env variables
export SIM_MODE=DC
export DP_URL="http://some.dp/to-dp"
java -jar toop-simulator-0.10.8-bundle.jar
The simulator will launch a /to-dc endpoint as well as the toop-connector endpoints (/from-dc, /from-dp...) and
a command line interface that you can send requests from (please see toop-commander).
- As JVM ARG: -DSIM_MODE=SOLE
- As ENV variable: export SIM_MODE=SOLE
- via toop-simulator.conf: toop-simulator.mode="SOLE"
In SOLE mode, toop-simulator launches a toop-connector without a DC or DP simulation and no CLI.
If the DC_URL and DP_URL variable are omitted, then the default values (http://localhost:8080/to-dc
and http://localhost:8082/to-dp) will be used.
Assuming that you have some external DC and DP urls (e.g. http://memberstate.a:8080/to-dc and http://memberstate.b:8080/to-dp),
to launch the simulator in SOLE mode, run the following command
# using JVM ARGS
java -DSIM_MODE=SOLE -DDC_URL="http://memberstate.a:8080/to-dc" \
-DDP_URL="http://memberstate.b:8080/to-dp" \
-jar toop-simulator-0.10.8-bundle.jar
# or alternatively set env variables
export SIM_MODE=SOLE
export DC_URL="http://memberstate.a:8080/to-dc"
export DP_URL="http://memberstate.b:8080/to-dp"
java -jar toop-simulator-0.10.8-bundle.jar
The simulator will launch toop-connector endpoints (/from-dc, /from-dp...) and wait for requests and responses
from the configured DC and DP endpoints.
- By avoiding the SIM_MODE argument (DP mode is default)
- As JVM ARG: -DSIM_MODE=DP
- As ENV variable: export SIM_MODE=DP
- via toop-simulator.conf: toop-simulator.mode="DP"
In DP mode, toop-simulator launches a toop-connector and a toop-commander with a DP that is directly connected
to the simulator and NO CLI (because the responses from toop-commander's DP interface are automatic).
The architecture view for the DP mode is given below.
To run the simulator in DP mode, run the following command
# by omitting the SIM_MODE variable (DP is default)
# and DC_URL (which will be defaulted to http://localhost:8080/to-dc
java -jar toop-simulator-0.10.8-bundle.jar
# using JVM ARGS
java -DSIM_MODE=DP -DDP_URL="http://some.dp/to-dp" -jar toop-simulator-0.10.8-bundle.jar
# or alternatively set env variables
export SIM_MODE=DP
export DC_URL="http://some.dc/to-dc"
java -jar toop-simulator-0.10.8-bundle.jar
The DC_URL variable can be omitted, in which case the default DC url (http://localhost:8080/to-dc) will be used.
When the simulator is started, it creates a file named toop-simulator.conf in the current directory
if it doesn't exist. This is a HOCON file that allows configuring the simulation modes, http ports and endpoints.
Sample toop-simulator.conf
toop-simulator {
#the simulator mode, one of SOLE DC, DP
mode = "DP"
mode = ${?SIM_MODE}
#Used only in DC Mode
dcPort = 8080
dcPort = ${?DC_PORT}
#Used only in DP mode
dpPort = 8082
dpPort = ${?DP_PORT}
#used only if mode != DC
dcURL = "http://localhost:8080/to-dc"
dcURL = ${?DC_URL}
#used only if mode != DP
dpURL = "http://localhost:8082/to-dp"
dpURL = ${?DP_URL}
#The simulator will run the connector on this port
connectorPort = 8081
connectorPort = ${?CONNECTOR_PORT}
# Since V0.10.7
# should we simulate the gateway connection or not?
# if true then the gateways are skipped and this simulator instance works as
# a compound connector of the two member states, otherwise (false) the MEM message
# is passed to the gateway configured with the key toop.mem.as4.endpoint and all
# the toop.mem.as4.* configurations (see toop-connector.properties) become significant
mockGateway = true
mockGateway = ${?MOCK_GATEWAY}
}Note That the configuration key mockGateway has been added since V0.10.7-SNAPSHOT, and does not exist in 0.10.6
You don't have to directly edit this file (unless you want to persist your settings). For every configuration
item there is an ENV or JVM_ARG alternative. For example you can run the toop-connector on a different port by
explicitly changing the toop-simulator.connectorPort, or setting CONNECTOR_PORT variable via ENV/JVM_ARG:
java -DCONNECTOR_PORT=8091 toop-simulator-0.10.8-bundle.jarWindows users, please see Setting Environment variables on Windows.
The simulator mimics the TOOP Directory, SMP, SMS and Message Exchange Modules.
The Directory and SMP simulators provide discovery service by consuming the file
discovery-data.xml, SMS does a static mapping with respect to the definitions
in the file sms.conf. These files are created in the current directory with default
values if they don't exist.
You may want to add discovery information for a country and participant id. In this case, you need to
modify the discovery-data.xml file. The sample structure of this file is as follows:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

</sim:ServiceMetadataList>The file contains a root ServiceMetadataList that can contain multiple CountryAwareServiceMetadata elements.
A CountryAwareServiceMetadata element has an attribute called countryCode that takes
a two letter country code.
A CountryAwareServiceMetadata element may contain multiple ServiceMetadata elements.
The ServiceMetadata type
has been inherited from the XSD Schema
of the OASIS Service Metadata Publishing (SMP) Version 1.0.
NOTE: Since the message exchange service is simulated, the certificate entry might be a dummy byte array (e.g. AA== which is a base64 encoded 1 byte array). But if you want to disable MEM mocking and communicate with a real gateway, then you have to provide a real base64 encoded certificate. For ease of use, the simulator also supports reading the certificates from external files by providing their file system paths in an extension called :CertFileName as given in the below example.
<bdxr:Endpoint transportProfile="bdxr-transport-ebms3-as4-v1p0">
<bdxr:EndpointURI>https://www.as4gateway.com/msh</bdxr:EndpointURI>
<!-- we are using cert file, so this binary value is dummy. See the extension-->
<bdxr:Certificate>AA==</bdxr:Certificate>
<bdxr:ServiceDescription>RO 1 Endpoint</bdxr:ServiceDescription>
<bdxr:TechnicalContactUrl>Jerry</bdxr:TechnicalContactUrl>
<!-- In order not to violate the SMP schema we have to provide
our certficate file name in an extension -->
<bdxr:Extension>
<!-- Put the certificate path in this element (DER or PEM) file -->
<sim:CertFileName>path/to/my/certificate.der</sim:CertFileName>
</bdxr:Extension>
</bdxr:Endpoint>You have to provide a dummy base64 string in the bdxr:Certificate element for successfull schema parsing,
even though it will be ignored by the simulator.
. The certificate file may be a
DER or a
PEM file.
The simulator reads the sms.conf file that contains all the information about the semantic mapping of
the concepts from and to the toop namespace (http://toop.eu/registered-organization).
The default contents are the predefined mappings for elonia and freedonia.
sms.conf is a HOCON config file that contains a list of mapping groups
each containing source and destination namespaces (i.e. sourceNS and targetNS)
and a mapping of concepts. A fragment from sms.conf is given below:
Mappings=[
{
sourceNS="http://toop.elo/elonia-business-register"
targetNS="http://toop.eu/registered-organization"
concepts {
"EloniaActivityDescription"="activityDescription"
"EloniaBirthDate"="birthDate"
"EloniaCapitalType"="capitalType"
"EloniaCompanyCode"="CompanyCode"
"EloniaCompanyName"="companyName"
#... and the rest
}
},
{
sourceNS="http://toop.fre/freedonia-business-register"
targetNS="http://toop.eu/registered-organization"
concepts {
"FreedoniaActivityDescription"="activityDescription"
"FreedoniaBirthDate"="birthDate"
"FreedoniaCapitalType"="capitalType"
"FreedoniaCompanyCode"="CompanyCode"
#... and the rest
}
}
]
You can add as many mappings as possible. You don't need to add the inverse of the mappings as the simulator does this for you (with the current assumption that mappings are one-to-one).
Note: The value of toop.smm.namespaceuri in the toop-connector.properties is important to be set to the namespace of
the DP that the simulator will send the asic requests to. The simulator includes a toop-connector.properties file within
the jar file. Please see
TOOP Connector Deployment and Configuration Guide
for more information on configuring toop-connector.properties
The below diagram shows the internal architecture of toop-simulator.
-
The directory and capability lookup (SMP) is served by the DiscoveryProvider module which implements IR2D2ParticipantIDProvider and IR2D2EndpointProvider interfaces by interpreting
discovery-data.xmland serving participant identifiers and R2D2 endpoints. -
The MultiNsSMMConceptProvider module implements ISMMConceptProvider and interprets
smm.confand provides translations from and to thetoop.smm.namespaceuri. -
The MockDCDPMessageExchange module implements IMessageExchangeSPI and shortcuts a connector to connector communication by skipping the four corner model.
The interfaces can be found under toop-connector-api
