TIF ENOVIA Connector - Synchronous Integration

18 October 2016

1. Synchronous Integration

From a performance perspective one should avoid using synchronous integrations, since that may block the user from working with the ENOVIA™ system in a smooth way. However, in some situations it is necessary to run a job synchronously.

Remember that TIF is running in a different process than your ENOVIA app.

If you have started a transaction and within that transaction performs a synchronous call to TIF, you need to extract the data you need (the payload) on the TIF server before you do the TIF call. Otherwise you may due to transaction isolation not be able to read the correct data OR you may in worst case cause a dead-lock.

On the caller side, you typically use the method SynchCreateNewJob.setPayload(String) to send additional data to the TIF instance.

1.1. Configuration

In order for the client to know where the TIF server is located, you need to set some environment variables.

TIF Server URL

The URL to the TIF server is resolved in the following order:

  1. Java system parameter: System.getProperty("tif.server.url")

  2. TVC Init parameter: tif.server.url (set in web.xml or /WEB-INF/classes/tvc.properties).

  3. ENOVIA RPE Parameter: TIF_SERVER_URL

  4. ENOVIA Ini Parameter: TIF_SERVER_URL

  5. Environment Variable: TIF_SERVER_URL

Context Path

The default is /enovia/tif-internal. Unless you have changed this via the module settings file, you do not need to set this. Otherwise, this value is resolved in the same order as above:

  1. Java system parameter: System.getProperty("tif.server.contextPath")

  2. TVC Init parameter: tif.server.contextPath (set in web.xml or /WEB-INF/classes/tvc.properties).

  3. ENOVIA RPE Parameter: TIF_SERVER_CONTEXTPATH

  4. ENOVIA Ini Parameter: TIF_SERVER_CONTEXTPATH

  5. Environment Variable: TIF_SERVER_CONTEXTPATH

1.2. Programatically Invoke

You can embed the invocation of a synchronous job in your own code by using the TIF classes like shown below:

...
import com.technia.tif.enovia.api.synch.InvokeJobResponse;
import com.technia.tif.enovia.client.synch.SynchCreateNewJob;
...

Map<String, String[]> paramMap = ...
SynchCreateNewJob req = new SynchCreateNewJob();
req.setJobCfg(jobCfg);
req.setParamMap(paramMap);
//req.setPayload(aString);
InvokeJobResponse response;
try {
    response = req.run();
} catch (XMLException | IOException e) {
    throw new AppException("Unable to run integration", e);
}
if (response.getHasError()) {
    throw new AppException(response.getErrorMessage());
}

String firstResult = response.getFirstResult().getResponse();
...

1.3. Built’in TVC Form Processor

If you use the TVC Structure Browser component within your ENOVIA web application, you can use a built in processor for name-allocation from an external system.
