Yes. First, your UPLOADS table must include FILESIZE (integer) and FILETYPE (varchar) columns. Second, you have to enable filesize and/or filetype in options parameter for store(...) method : <br>
&nbsp;...<br>
&nbsp;HashMap options = new HashMap();<br>
&nbsp;options.put(&quot;dbstore.filesize&quot;,&quot;enabled&quot;);<br>
&nbsp;options.put(&quot;dbstore.filetype&quot;,&quot;enabled&quot;);<br>
&nbsp;upBean.store(mrequest, &quot;uploadfile&quot;, options);<br>

Yes, UploadBean could store custom column(s) through &quot;dbstore.customcolumn&quot; property in options parameter for store(...) method. For instance, if you have a CREATED_DATE column in your UPLOADS table then you could pass the date instance to be stored through :<br>
&nbsp;...<br>
&nbsp;HashMap options = new HashMap();<br>
&nbsp;options.put(&quot;dbstore.customcolumn.created_date&quot;,new Date());<br>
