SYMPTOM:
When running a custom Java application based on Web APIs in Strategy SDK 9.x, the following error is encountered intermittently:
com.Strategy.web.objects.WebObjectsException: Expected execution status 1, received status X
where 'X' is an integer.
This error is most often encountered when executing a report instance or when creating a new empty report instance. The error is intermittent.
CAUSE:
The 'execution status' refers to the interface com.Strategy.webapi.EnumDSSXMLStatus. In many cases, the next call in the application expects report results to be ready, even when empty, before trying to retrieve data or perform any type of manipulation. Depending on the Strategy Intelligence Server workload, the time it takes to retrieve the same amount of data will differ even if the report has been cached. Since, by default, report execution is asynchronous, the application will not wait for the processing on Strategy Intelligence Server to finish but will trigger the next call to be executed.
ACTION:
Make sure that the report execution call is synchronous. This can be done by a call to setAsynch(false) or to setMaxWait(-1). Call to setMaxWait(-1) is preferable, as shown below:
WebReportInstance rptInst = reptSrc.getNewInstance("XXX");
//rptInst.setAsync(false); this call is equivalent to the setMaxWait(int i) call below and could be used interchangeably
rptInst.setMaxWait(-1);
rptInst.setPollingFrequency(250);
int status = rptInst.pollStatus();
WebReportData repData = rptInst.getResults(); Using setMaxWait(-1) means that the next call will not be triggered until the report returns results or errors out on Strategy Intelligence Server (exceeds governing settings etc.).
ADDITIONAL INFORMATION: The Strategy SDK allows you to customize the standard Strategy Web interface, and extend and integrate the Strategy business intelligence functionality into other applications. However, before changing the way Strategy Web products look or behave, it is helpful to understand how the application is built. For more information regarding the Strategy Web architecture or the process of customizing Strategy Web, please refer to Strategy Developer Zone (
