问题
I've created simple "Hello world" portlet and just added
<use-default-template>true</use-default-template>
to the portlet section of liferay-portlet.xml file.
Portlet stopped to work with the following exception in the log
11:29:03,973 ERROR [PortletLocalServiceImpl:656] com.liferay.portal.kernel.xml.DocumentException: Error on line 13 of document : The content of element type "portlet" must match "(portlet-name,icon?,............ and so on
The name of my tag is present here.
Why is this? Is this tag obsolete or something?
Thanks.
回答1:
The problem is the order of the tags on the liferay-portlet.xml. You should put the tags on the right order following the "spec" (DTD).
回答2:
Yes problem with DTD order only.
You can can see some good articles of liferay portal.
