    <p>Own answer:</p> <p>I have put in the path a jrxml that actually connects to the database and gets some real data out and suddendly it worked, the PDF opened in mozilla, but the Exception keeps happening. I do not know how I can throw and exception (I have debugged and the Exception happens in the same place) and be able to see the PDF.</p> <p>So I can only keep searching for what actually happens here. I will answer with anything I find (probably on monday).</p> <p>Thanks simonlord and Jim Rush for your help! :)</p> <p>Edit: By the way, here is the stacktrace (it's in Spanish, if needed I will translate anything you don't understand): Edit again: Seems I didn't copy the '1' in the 15th-Jan-2010... could create confusion about a trace from the 5th-Jan insetad. Corrected.</p> <pre><code>15-ene-2010 13:47:03 org.apache.catalina.core.ApplicationDispatcher invoke GRAVE: El Servlet.service() para servlet jsp lanzó una excepción java.lang.IllegalStateException:

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
