error exporting data to excel with display tag 1.1.1

Cruz Diaz, Manuel David



I’m a new user of this mailing list. I’m not English, sorry for my English poor language.


We’ve a problem with our J2EE application, which uses Display Tag library 1.1.1. The problem is that we’ve a “Java heap space” error when we try to export the result of a SQL query to a excel using the following code:


<c:url value="/admin/inscripcion/" var="listarBuscarInformeSegAction"></c:url>

<display:table name="informeSeg" id="seg" pagesize="20" requestURI="${listarBuscarInformeSegAction}"

    class="listadoInforme" cellpadding="2" cellspacing="0"

    style="margin-left: auto;margin-right: auto;" export="true">




The SQL query returns 32000 records. The memory configuration of our server (Jboss) it’s up 256 MB max. We can’t increase the memory of the server because the client doesn’t let us to do that.


Do you know if this error is a bug of the display tag library? Can you tell us anything more about this error? How can we solve this error?


Thank you very much.



Un saludo,

Manuel D.
