Hello Community !

I am working with the following combination:
Serverside: SQL Express Server & jRDC2 Server with jtds 1.3.1
Clientside: B4J Application with newest DBRequestManager

B4J is throwing the following exception:

<head>
<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/>
<title>Error 500 </title>
</head>
<body>
<h2>HTTP ERROR: 500</h2>
<p>Problem accessing /rdc. Reason:
<pre> java.lang.RuntimeException: Cannot serialize object: net.sourceforge.jtds.jdbc.ClobImpl@156128a</pre></p>

*** Error: java.lang.RuntimeException: Cannot serialize object: net.sourceforge.jtds.jdbc.ClobImpl@156128a

This exception is thrown if I add a column into the select query which has varchar(max) as datatype. If I
do not add this column to the select query, the exception is not thrown.

Any idea ?

Thank you very much in advance!

Regards
