We have integrated crystal reports with our web application for our reporting solution. While most of the reports works fine, one particular report has
an intermittent issue. When the underlying query for the report takes more than 5 minutes to execute and give a result, the crystal report viewer throws back a null pointer exception, we checked that the underlying query is submitted to the DB and is still running while the crystal report viewer has thrown and exception. When the same report, if the query executes within 5 minutes, is able to retrieve the result and show it on the screen. Any suggestion as to how to resolve this.
