JSPs in CMSPortlet

[psalvadori]

Hi all,

I have a problem trying to render a jsp page into the CMS portlet.

What I did is to upload my jsp page with the CMSAdmin tool of the portal, created an instance of the CMSPortlet in my portal instance and assigned as default page of the CMSPortlet the uploaded page.

If this page is a simple html page all works fine,
If this page is a jsp page, what I see is jsp code (i.e. <%=my_variable%> instead the value of my variable) mixed with right html content;

Is there a way to compile my jsp page before passing it to the cms portlet doView method?

Thanks, Paolo.

paolo: i'm relative new in jboss, and my question for you is that how you make a page the default page in cms portlet? i create a new intance of the portlet in helloportal and when i edit the index the page its the same for both portals. can you help me?

thanks
Nicolas

First of all I used CMSAdmin tool to create a folder at the same level of the "default" folder and uploaded my file jsp(or html) in that folder. Now the path is MyFolder/MyFile.
Then, in the portlet descriptor of my portal instance (portlet.xml), when I declare my CMSPortlet, I set the index page as follow:


<portlet-name>MyCMSPortlet</portlet-name> <portlet-class>org.jboss.portal.core.portlet.cms.CMSPortlet</portlet-class>
<init-param>
Default path to index page.
indexpage
/MyDir/MyFile
</init-param>

<mime-type>text/html</mime-type>
<portlet-mode>VIEW</portlet-mode>

<portlet-info>
CMS
</portlet-info>


note that is necessary that the name of the init-param must be "indexpage" because the CMSPortlet (I discovered it in the source file) check for an attribute with this name.

I hope this help you.
Paolo.

In the previous post I miss some character; The correct portlet.xml is the following:

<portlet>
 <portlet-name>MyCMSPortlet</portlet-name>
 <portlet-class>org.jboss.portal.core.portlet.cms.CMSPortlet</portlet-class>
 <init-param>
 <description>Default path to index page.</description>
 <name>indexpage</name>
 <value>/MyDir/MyFile</value>
 </init-param>
 <supports>
 <mime-type>text/html</mime-type>
 <portlet-mode>VIEW</portlet-mode>
 </supports>
 <portlet-info>
 <title>CMS</title>
 </portlet-info>
</portlet>

thanks paolo for the information, but i have another doubt, y deploy the helloworldportlet-ear dir from the examples portals....i create the new instance of the cms and the only place where i found the file portal.xml was the *.war of the example portal.

the steps you said i made them but its correct to edit the portal.xml of the war fine in the helloportal??


thnx very much for helping a new user of jboos portal.

[noicangi]

hi! here i add more information, i create de folder with an html /prueba/prueba.html and create myCMS instance of the cmsportlet. next i add to the helloportal on the *.war file in portlet.xml added the xmlcode you said but here is the error:

for noicangi:

1) You must modify portlet.xml, not portal.xml

2) You are right, i forgot to tell you another thing; for the portal instance you use you must start some services, one of them is CMS service. To do that you must add an xml in the WEB-INF dir of your portal instance: jboss-portlet.xml
In this file you must specify the services to start with your portal instance; I think you only need CMS Service but I suggest you to do like me, putting inside all services. Here my jboss-portlet.xml (part of the one in jboss-portal.sar):

<portlet-app>

this may correct your last error.

for glodo:

I'm sorry but I haven't tried yet the CatalogPortlet so I can't help you for this. Anywere I'll contact you if i will discover something. If you find any news about rendering jsps contact me please.
Paolo.

[noicangi]

paolo thanks, i will try again with the tips you said.

i will post any news

thanx for helping newbies

nx.

[glodo]

Ok.. i will contact to you.. i just say you.. i think that with the CMSPortlet you can not find a solution for the jsp.. because in the portlet specify the mime-type like text/html, i dont know if this the cause which you can not display a jsp.. if i am wrong please let me know..ok?
thanks in advance
glodo

[noicangi]

paolo:

i followed your instructions, icreate on the cms admin a folder with an html file u, all under the root dir.
in the war file of the helloportal i added the jboss-portlet.xml, in the hellowolrd-object.xml i change the overwrite by keep tags and the portlet.xml y added the code you said.

i create and instance of myCMSportlet and then create a window to a page...but when i reload the page doesn't apears.....can you help me.....what i'm doing wrong?

[noicangi]

paolo, thank you very much, your explanation was very clear, i found that the page that the cmsportlet points must be in english, i was uploading myindex.html in spanish so the cmsportlet desapeared and there was a error in console,


for the guys who correct the bugs.....CMSPORTLET MUST point a page in english.....if you point a page in spanish the portlet breaks.

[roy.russo]

No. The CMSPortlet retrieves the version of the page that matches the user's locale settings.

[noicangi]

ok but if there is only a page in spanish, then the portal will try to use the default page in english, if the page in englsih doesn't exist what happens to the cmsportlet Instance?

[roy.russo]

If there is only a page in spanish, and the CMSPortlet is set to render english as default, it will break. However, if the locale is set to spanish in the user's browser, it will render the spanish page.

I will detail this in the docs, as it seems to be a recurring question of how the logic works.
