RE: Exception - Liferay Portlet3 Requires 3.0 opt-in

How did you fix the problem? Not using "javax.portlet.version=3.0" at all?

None of the Liferay portlets have "javax.portlet.version=3.0" set, so no help in using the Liferay code as an example.The issues happens typically when using PortletURLFactoryUtil because the PortletURLImpl.java code checks the portlet(ID) version and decides that _portletSpecMajorVersion == 3. So it sets up the PortletURLImpl as a 3.0 version. BUT the request that gets passed around is _portletSpecMajorVersion < 3 (because the request is from on of the Liferay portlets) so this throws an exception down the line.

We have the same issue, it looks like the Request object that is passed to the AssetRenderer is not 3.0.

Hi Jamie. That's fine. Same impression here... Thanks.

Hi Filipe,
My apologies I missed the fact that you already had javax.portlet.version=3.0 set in the app. What's strange is it appears to be the Asset Publisher that is displaying the error.

Hello Jamie,I could not found any other property to set.Do you know which one is missing from my configuration?
Thank you

Hi Filipe,

It looks like you may need to set an addtional property to enable portlet 3.0: https://portal.liferay.dev/docs/7-1/reference/-/knowledge_base/r/breaking-changes#upgrade-considerations

Hi everyone.I'm trying to enable portlet 3.0 in my app, using Liferay 7.2 CE.
I've already configure my Portlet class like this

@Component(
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;immediate = true,
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;property = {
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"com.liferay.portlet.display-category=category.hidden",
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"com.liferay.portlet.scopeable=true",
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"javax.portlet.display-name=Guestbooks",
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"javax.portlet.expiration-cache=0",
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"javax.portlet.init-param.portlet-title-based-navigation=true",
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"javax.portlet.init-param.template-path=/",
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"javax.portlet.init-param.view-template=/guestbook_admin/view.jsp",
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"javax.portlet.name=" + GuestbookPortletKeys.GUESTBOOK_ADMIN,
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"javax.portlet.resource-bundle=content.Language",
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"javax.portlet.security-role-ref=administrator",
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"javax.portlet.supports.mime-type=text/html",
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"com.liferay.portlet.add-default-resource=true",
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;"javax.portlet.version=3.0"
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;},
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;service = javax.portlet.Portlet.class
)

However I still getting the following exception:
