Drools Rule - Event not forwarded: "Object is not an instance of declaring class"

[Andreas Grünwald]

Hello,

i am trying to call a method of the Jira Issue service domain since yesterday, however I am still caught with a drools rule problem. The workflow is as follows:

1. I am running a component called "synchronizerService". 
2. Within this component (after startup) I use the utilsService and wiringService to connect to a connector of the domain "Spreadsheet" called "MSSpreadsheetService".
3. I call a method of the "MSSpreadsheetService" to raise a test event. The event is initialized and fired.
4. I created a drools rules called "InsertSpreadsheetEvent.rule" which is fired when org.cdlflex.domain.spreadsheet.event.InsertRecordEvent(). This works so far.
5. Within the rule I perform the following steps:
6. connect to the issue domain with: IssueDomain issueService = (IssueDomain) OsgiHelper.getResponseProxy(e, IssueDomain.class);
   
7. Create a new Issue: org.openengsb.domain.issue.Issue issue = new org.openengsb.domain.issue.Issue();
8. try to persist the issue: issueService.createIssue(issue);
   
9. (8) does not work. Please see the message below. Based on the thrown exception (see below; I  caught h it with drools and printed it to the System.out) I have no idea what the problem is. 

I already checked:

The content of assembly/*/etc/issue+issue+jira-root.connector  is:

domainType=issue

connectorType=jira

property.location.root=issue/jira

This should be in accordance to the service properties in the blueprint file of the jira issues connector: 

<service-properties>
  <entry key="domain" value="issue" />
  <entry key="connector" value="jira" />
  </service-properties>
</service-properties>

Can you please provide me with some information how to resolve this issue, where to start, etc.?
Thank you very much, Andreas

What is interesting is that I just found out that

IssueDomain issueService = (IssueDomain) OsgiHelper.getResponseProxy(e, IssueDomain.class);

retrieves the following object:

org.cdlflex.connector.spreadsheet.excel.internal.MSSpreadsheetService@f950855

How is that possible? MSSpreadsheetService is of the domain SpreadsheetDomain.class. Its domain is spreadsheet and its connector is "spreadsheet-excel".

[Felix Mayerhuber]

Hi,

I suppose that the error is located at exactly this problem. Are you
sure the service (MSSpreadsheetService) is exported under the correct
data? How does the pom.xml of the corresponding bundle looks like?

kind regards
Felix

[Andreas Grünwald]

Hello Felix,

I just had a look at the OsgiHelper source (https://github.com/openengsb/openengsb/blob/6efebb44a0138d8138e6311d384d51aae621b3c2/components/workflow/src/main/java/org/openengsb/core/workflow/drools/OsgiHelper.java) and things now become a little bit more obvious.

As it seems the location of the service is determined by using the origin context of the event. The origin information of the event however contains (origin: spreadsheet+spreadsheet+excel+root). 

What I intended to do is to get access to the issueService via telling the OsgiHelper that I want to get the service of the type "IssueDomain.class" (call IssueDomain issueService = (IssueDomain) OsgiHelper.getResponseProxy(e, IssueDomain.class)). 

Do which export information in the pom.xml are you referring do? May you please provide an example of a pom with the export information that you are talking about?

I only can tell you that the pom's of the domains (SpreadsheetDomain for MSSpreadsheetService and IssueDomain for Jira Issues) contain the following information, respectively:

pom for spreadsheet domain:

  <properties>

    <bundle.namespace>${project.artifactId}</bundle.namespace>

    <domain.name>SpreadsheetDomain</domain.name>

    <domain.name.short>spreadsheet</domain.name.short>

  </properties>

Hello Andreas,

can you try to inject the domainservice by defining it in the .global
file instead of using the getResponseProxy method? Does that work?

[Andreas Grünwald]

Hello Michael,

how would that look like?

I cannot define 

org.openengsb.connector.jira.internal.domain.JiraServiceImpl jiraService

directly, because the service is internal and the events are not injected automatically? 

I could use the service factory (IssueServiceInstanceFactory), was that what you meant?  But in that case I don't know how to inject the events and the instanceId. Maybe you can give me an example?

Best regards,

[Michael Petritsch]

Hi,

please use the interface of the implementation, not the implementation.

br

[Andreas Pieber]

In addition please use only the domain interface. If there are more than one provider the context or additional routing logic is responsible for getting you the right endpoint instance; it's not the requirement of the process itself!

Kind regards,
Andreas

[Andreas Grünwald]

Hello,

actually this is my question: How do I call an (abstract) service implementation within the drools rule context correctly? As there is no documentation about that I don't know what the correct way of doing so is? 

Does the logic automatically inject the correct service if the abstract domain is defined in the .global-file? But if so, how can one select the appropriate implementation in the case that there are more than a single implementation?

Would be great if you could provide me with an example or something similar.

Best, Andreas

[Michael Petritsch]

Hi Andreas,

if there is just a single service implementation for a service
interface, there are some services in the cdlflex framework that you
can take as an example. e.g. the backuprestore service. Look at the
service definitions in the application-context.xml. If you define it
like that you can add this service as a reference in another bundle's
application-context.xml or you can add it to the .globals file (as I
have mentioned in my previous mail) and use it in a drools rule.

I've never tried to implement more than one service for a single
interface though, so I don't have an answer for that case.

br

[Andreas Pieber]

Hey Andi,

Have you already checked the documentation? The wiring thing is explained here [1]. [2] contains the userinterface part to wiring. Here another point for service locations [3]. [4] shows how to combine different connectors.

While the documentation isn't perfect, it's definitely a rich well of information!

Kind regards,
Andreas
