I am unable to export table to csv file using dsiplaytag. I have read the
configuration, created the filter but still i am not able to do it.
i am using struts implementation version 1.2.9 and here is my displaytag
configuration
*JSP CODE*
*
<display:table id="useractivity" name="userActivityList" export="true">
<display:column property="registrationDate" title="Registraiton
Date"/>
<display:column property="codeVerification" title="Verification
Date"/>
<display:column property="lastLogin" title="Last Login"/>
<display:column property="loginCount" title="Login Count"/>
<display:column property="sentCount" title="Sent Count"/>
<display:column property="lastSent" title="Last Sent"/>
<display:column property="receivedCount" title="Received Count"/>
<display:column property="lastReceived" title="Last Received"/>
</display:table>
*
*displaytag.properties*
*
export.types=csv excel xml
export.excel=false
export.csv=true
export.xml=false
export.csv.class=org.displaytag.export.CsvView
export.csv.label=CSV
# include header parameter is forwarded to your export view
export.csv.include_header=true
# if set, file is downloaded instead of opened in the browser window
export.csv.filename=User Activity.csv
*
*here is my web.xml file for the filter*
* <!-- DISPLAY TAG SPECIFIC -->
<filter>
<filter-name>ResponseOverrideFilter</filter-name>
<filter-class>org.displaytag.filter.ResponseOverrideFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>ResponseOverrideFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>ResponseOverrideFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
