Hello All,
I am using Displaytag framework for pagination & exporting purpose. In that i am also using Strut2Tiles Integration.
Whenever i am calling any
action class it will returning me a list & through Displaytag i am successfully displaying record on my page. For that my jsp page's code looks like :
<s:set name="selectedPageSize" value="selectedPageSize" scope="request"/>
<s:set value="accountList" scope="request" name="accountList"/>
<display:table name="accountList" export="true" class="table" requestURI="" id="accountList" pagesize="${selectedPageSize}" >
<display:setProperty name="export.pdf" value="true" />
<display:column property="id" sortable="true" class="sort-title"/>
<display:column property="name" sortable="true"/>
<display:column property="contactPerson" sortable="true"/>
<display:column property="phone1" sortable="true"/>
<display:column property="phone2" sortable="true"/>
<display:column property="fax" sortable="true"/>
<display:column property="email" sortable="true"/>
<display:column property="webSite" sortable="true"/>
<display:column property="address1" sortable="true"/>
<display:column property="address2" sortable="true"/>
<display:column property="countryId.name" title="Country" sortable="true"/>
<display:column property="stateId.name" title="State" sortable="true"/>
<display:column property="countryId.name" title="City" sortable="true"/>
<display:column property="isDeleted" sortable="true"/>
<display:column title="Delete">
<s:url id="removeUrl" action="finance/deleteAccount.
action">
<s:param name="id" value="#attr.accountList.id" />
</s:url>
<s:a href="%{removeUrl}" theme="ajax" targets="accountList">Remove</s:a>
</display:column>
<display:column title="Update">
<s:url id="updateUrl" action="finance/updateAccount.
action">
<s:param value="#attr.accountList.id" name="id"/>
</s:url>
<s:a href="%{updateUrl}&action=update" targets="accountlist">Update</s:a>
</display:column>
Actually this page is displaying through tiles configuration.
Here i have enabled the export option, so it is showing me the exporting options like CSV, EXCEL, XML. But whenver i am clicking on that CSV link, my web browser hanged, means nothing is displayed on it
For that exporting solution i have also added
filter in my web.xml. My web.xml looks like:
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
<filter-name>ResponseOverrideFilter</filter-name>
<filter-class>org.displaytag.
filter.ResponseOverrideFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>ResponseOverrideFilter</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>ResponseOverrideFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
<listener>
<listener-class>org.apache.struts2.tiles.StrutsTilesListener</listener-class>
</listener>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/webApplicationContext.xml</param-value>
</context-param>
<welcome-file-list>
<welcome-file>jsp/welcome.jsp</welcome-file>
</welcome-file-list>
I have also included following list of libraries of displaytag :
1) displaytag-1.2.jar
2) displaytag-export-poi-1.2.jar
3) displaytag-portlet-1.2.jar
The exception that i am getting is :
2009-05-09 12:02:38,234 DEBUG (org.displaytag.tags.TableTag:1524) - Exportfilter NOT enabled
2009-05-09 12:02:38,312 WARN (org.displaytag.tags.TableTag:63) - Exception: [.TableTag] Unable to reset response before returning exported data. You are not using an export
