[jira] Created: (TUSCANY-1309) NPE if SCDL uses component reference
that is not defined consistently in the implementation
NPE if SCDL uses component reference that is not defined consistently in the implementation
-------------------------------------------------------------------------------------------
Key: TUSCANY-1309
URL: https://issues.apache.org/jira/browse/TUSCANY-1309
Project: Tuscany
Issue Type: Bug
Environment: Win XP
Reporter: Simon Laws
Assignee: Simon Laws
Priority: Minor
For example,
public class AlertsServiceImpl {
private RSSCheckerService rssChecker;
private AlertsSourcesService alertsSources;
@Reference
public void setRssChecker(RSSCheckerService rssChecker) {
this.rssChecker = rssChecker;
}
// missing explicit reference defintion for alertsSources.
...
}
Then the SCDL...
<component name="AlertsServiceComponent">
<implementation.java class="org.apache.tuscany.sca.samples.aggregator.AlertsServiceImpl" />
<reference name="rssChecker" target="RSSCheckerComponent"/>
<reference name="alertsSources" target="AlertsSourcesServiceComponent"/>
</component>
Results in NPE

[jira] Resolved: (TUSCANY-1309) NPE if SCDL uses component
reference that is not defined consistently in the implementation
Posted by "Raymond Feng (JIRA)" <tu...@ws.apache.org>.

Raymond Feng resolved TUSCANY-1309.
-----------------------------------
Resolution: Invalid
If the reference/service under the <component> doesn't match what are declared (or introspected) on the componentType, we produce a warning. In this case, the variable is not a SCA reference and no injection happens. So it's default to null and NPE is a user error.
