Post your config files, It sounds like your portlet.xml view-param JSF file is wrong.

sorry, this question is solved, thanks

another question is why I deployment portlet, but portlet instance didn't created, I must using admin to create one.

portlet-instance.xml

<instance-id>SimplestHelloWorldInstance</instance-id>
<portlet-ref>SimplestHelloWorld</portlet-ref>

Is anywhere wrong?

Hi uxa,

Have you created the default-object.xml or something-object.xml?

In your case, the content of the file should be something like:

<deployments>
 <deployment>
 <parent-ref>default</parent-ref>
 <if-exists>overwrite</if-exists>
 <page>
 <page-name>SimplestHelloWorld</page-name>
 <display-name>SimplestHelloWorld</display-name>
 <window>
 <window-name>SimplestHelloWorldWindow</window-name>
 <instance-ref>SimplestHelloWorldInstance</instance-ref>
 <region>center</region>
 <height>0</height>
 </window>
 </page>
 </deployment>
</deployments>

Cheers,
JP

Thanks jpviragine

yes, I have the default-object.xml, but I need using admin mode to create the portlet instance for my portlet object.

What I need to do, if I deploy portlet and I want it instance be created.

Uxa,

As you said that you have created portlet-instances.xml and default-object.xml. I think the problem is in your portlet.xml.

Please, take a look at: http://www.redhat.com/docs/en-US/Enterprise_Portal_Platform/4.3/html/Reference_Guide/descriptors_portlet.html for a correct usage of the three files.

uxa,

Change your default-object.xml to:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE deployments PUBLIC
"-//JBoss Portal//DTD Portal Object 2.6//EN"
"http://www.jboss.org/portal/dtd/portal-object_2_6.dtd">
<deployments>
 <deployment>
 <parent-ref>default</parent-ref>
 <if-exists>overwrite</if-exists>
 <page>
 <page-name>SimplestHelloWorld</page-name>
 <window>
 <window-name>SimplestHelloWorldWindow</window-name>
 <instance-ref>SimplestHelloWorldInstance</instance-ref>
 <region>center</region>
 <height>0</height>
 </window>
 </page>
 </deployment>
</deployments>

I try to use

<content>
 <content-type>portlet</content-type>
 <content-uri>
 SimplestHelloWorldInstance
 </content-uri>
 </content>

or

<instance-ref>SimplestHelloWorldInstance</instance-ref>

the result is the same
