Mime types / wsrp

Question

Hi all,
I'm trying to display an excel spreadsheet from within a jsp in a portlet over wsrp.
Whenever I make a request from the consumer, I get the error:
java.lang.IllegalArgumentException: MIME type [application/vnd.ms-excel] is not supported by the consumer/portal. Supported types(s) is(are) [ text/html  text/xml  application/xml  application/xhtml+xml  text/plain  image/png  */* ].
and looking at the wsrp request sent over by the consumer, the mimeTypes it says it supports are:
<v1:markupParams>
<v1:secureClientCommunication>false</v1:secureClientCommunication>
<v1:locales>en-GB</v1:locales>
<v1:locales>en</v1:locales>
<v1:mimeTypes>text/html</v1:mimeTypes>
<v1:mimeTypes>text/xml</v1:mimeTypes>
<v1:mimeTypes>application/xml</v1:mimeTypes>
<v1:mimeTypes>application/xhtml+xml</v1:mimeTypes>
<v1:mimeTypes>text/plain</v1:mimeTypes>
<v1:mimeTypes>image/png</v1:mimeTypes>
<v1:mimeTypes>*/*</v1:mimeTypes>
<v1:mode>wsrp:view</v1:mode>
My question is how do I get my consumer to support additional mimetypes?
I am using WLP 10 MP1.
Thanks

This can be solved in different ways.
1) You can use custom data transfer.please go through the below link
http://edocs.beasys.com/wlp/docs81/wsrp/custxfer.html
2) Use resource url tag library in your view on producer.
3) User resource proxy servlet on Consumer.
<!-- Proxy servlet to serve resources from producers -->
<servlet>
<servlet-name>com.bea.wsrp.consumer.resource.ResourceProxyServlet</servlet-name>
<servlet-class>com.bea.wsrp.consumer.resource.ResourceProxyServlet</servlet-class>
<init-param>
<param-name>resourceHeaderFilter</param-name>
<param-value>com.bea.wsrp.consumer.resource.CustomResourceHeaderFilter</param-value>
</init-param>
</servlet>
CustomResourceHeaderFilter.java:
package com.bea.wsrp.consumer.resource;
//import com.bea.p13n.util.debug.*;
import com.bea.wsrp.consumer.resource.ResourceHeaderFilter;
import com.bea.wsrp.consumer.resource.ResourceHeaders;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.ServletContext;
import java.util.*;
public class CustomResourceHeaderFilter implements ResourceHeaderFilter
private static final HashSet requestHeadersToSkip = new HashSet();
// Debug
//private static final Debug debug =Debug.getInstance(DefaultResourceHeaderFilter.class);
private static final Logger LOGGER = LoggerHelper.getLogger(CustomResourceHeaderFilter.class);
// By default, the following request headers will not be proxied private static final HashSet requestHeadersToSkip = new HashSet();
static
//requestHeadersToSkip.add("get");
     //requestHeadersToSkip.add("post");
     //requestHeadersToSkip.add("host");
     //requestHeadersToSkip.add("cookie");
     //requestHeadersToSkip.add("expect");
public ResourceHeaders getPassThroughHeaders(HttpServletRequest request, ServletContext context, String url)
     //request.getSession().getId()
ResourceHeaders passThroughHeaders = new ResourceHeaders(); List passThroughValues;
// All headers
Enumeration headerNames = request.getHeaderNames();
while(headerNames.hasMoreElements())
String name = (String) headerNames.nextElement();
if(requestHeadersToSkip.contains(name.toLowerCase()))
continue;
passThroughValues = new LinkedList();
Enumeration values = request.getHeaders(name);
while(values.hasMoreElements())
String value = (String) values.nextElement();
LOGGER.info("[Sending] " + name + ": " + value);
passThroughValues.add(value);
if (passThroughValues.size() > 0)
passThroughHeaders.addHeader(name, passThroughValues);
return passThroughHeaders;
}
