    <p>I have recently ported my data and file stores to Mongodb, which I am starting to really enjoy. I have what looks like a weird problem now.</p> <p>The Files Extension Filter in Tomohawk seems to be intercepting when my app when tries to write images for the user, from GridFS. I only want the filter to support my file upload - it should not be active when the system is pushing images to the user. Any ideas on how to stop it from intercepting these files would be very helpful.</p> <p>More details:</p> <p>I use Tomohawk file upload, and have the Extensions Filter enabled in my web.xml, in order to use it. I display images in the RichFaces MediaOutput control, which provides an output stream to which you can write your media bytestream. Everything was working fine when I stored the images as files, or within MySql.</p> <p>Now I am using the GridFSDBFile writeTo: OutputStream method to write my images to the RichFaces MediaOutput control. When I try to display my images, the File Extensions Filter seems to intercept it, and then Tomcat throws a TokenMgrException.</p> <p>I only want the filter to support my file upload - it should not be active when the system is pushing images to the user. Any ideas on how to stop it from intercepting these files would be very helpful.</p> <p>Here is the error:</p> <pre><code>Oct 16, 2012 2:17:29 AM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet [Faces Servlet] in context with path [/ilearn] threw exception [Servlet execution threw an exception] with root cause org.apache.tomcat.util.http.parser.TokenMgrError: Lexical error at line 1, column 1.

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).
