I have a stateful session bean which I call ReportManager. When my Java
application client calls the ReportManager's runReport method (which gets
results and prints them to a printer), the method runs twice!
I've distilled the code below:
public class ReportManager implements SessionBean
{
/* lots of other methods */
public String runReport(MyObject criteria)
{
/* I see this debug TWICE!!!! */
System.out.println("runReport(" + criteria + ")...");
/* get result set
* create a Printable object to respond to the printer
* call the Printable object's print method passing the result set
*/
}
}
In the same package I have a printable object like:
public class MyPrintableDocument implements Printable
{
public MyPrintableDocument
{
}
public void print(MyResultOjbect results)
{
/* create a printJob
* printJob.setPrintable(this);
* lookup the print service
* blah, blah, blah
* printJob.print(MyPrintRequestAttributeSet);
}
public int print(Graphics pg, PageFormat pageFormat, int pageIndex)
throws PrinterException
{
/* callback draws on the the Graphics object */
}
}
Again, when I call the ReportManagers' runReport() method it prints the
document twice and I see the debug in the method come out on the server
console twice. I think that it may have something to do with the printer
driver calling back the MyPrintableDocument. Anyone ever run into this? Any
suggestions?
Ultimately, I guess I would probably start using JMS so the RMI call to the
method would asynch.
BTW: you may have noticed that I am trying to use Java 1.4 beta 2 new print
API. I originally coded this in a regular Java application and it runs fine.
Gotta be something about the container.
