ERROR: application/pdf is not a supported mime type [duplicate]

Question

I am using Struts2 and Liferay for developing an application.

My struts.xml is as follows:

<action name="download" class="com.stp.portal.view.DownloadAction">
    <result name="success" type="stream">
        <param name="contentType">application/pdf</param>
        <param name="inputName">fileInputStream</param>
        <param name="contentDisposition">attachment;filename="abc.pdf"</param>
        <param name="bufferSize">1024</param>
    </result>
</action>

I basically want to download a pdf file from the server. But I get the following error:

10:05:55,782 ERROR [Jsr168Dispatcher:38] Could not execute action java.lang.IllegalArgumentException: application/pdf is not a supported mime type at com.liferay.portlet.MimeResponseImpl.setContentType(MimeResponseImpl.java:159)...

Don't know how to resolve this. Would really appreciate someone's help. Really need this to be done.

which server are you using? – Serpent

Which liferay version? Are you using Jsr286Dispatcher? – Norvun

Liferay 6.1 . No, i am not using Jsr286Dispatcher – Cembalo

@AleksandrM, according to his Exception, he's using Jsr168Dispatcher – Dorsiventral

See if this help; it is for Spring MVC, maybe it can be adapted to Struts2. – Dorsiventral

@AndreaLigios: Jsr286Dispatcher extends Jsr168Dispatcher so it class name maybe used in logs. – Norvun

Answer 1

Looking at the source code seems like only application/vnd.wap.xhtml+xml and text/html are allowed.
Source: http://grepcode.com/file/repo1.maven.org/maven2/com.liferay.portal/portal-impl/6.0.2/com/liferay/portlet/MimeResponseImpl.java

Is there any way to do it? I want to download a pdf file from server. I have already lost 2 days in this. – Cembalo

Answer 2

Put portletUrlType="resource" to the <s:url> tag which you use to create download link.

<s:url var="downloadUrl" action="download" portletUrlType="resource" />

not working for me, same error – Cembalo

@user2594235: Just tested, works for me. Have you re-deployed your portlet correctly? Liferay tends to cache everything. Also which version of Struts2 and portlet plugin? – Norvun

i hv redeployed the portlet, but still not working, i m using portlet pugin 2.2.3 – Cembalo

@user2594235: You could try with latest version, but AFAIK it should work in older versions also. Are you sure that changes are reflected in JSP? Try to change some text and see. Also post generated url. – Norvun
