OMNI portlet preference store issue

Hi,
Application is running on Staging environment and I want to move it to UAT clustered environment. Portlet application as well consumer application (Portal) deployed successfully. After that I have run persistancemigration tool for WSRP portlet preferences and copy them to UAT. At this stage, my portal and WSRP/JSR portlet start running. After that i tried to run migration tool to export omni portlet preferences in following way:-
1. I have set classpath for MigrationTool.
2. Test the classpath as follow:-
C:\>echo %classpath%
.;D:\Program Files\J-Integra\Exchange\lib\jintegra.jar;D:\Program Files\J-Integr
a\Exchange\lib\cdo.jar;.;D:\Program Files\J-Integra\Exchange\lib\jintegra.jar;D:
\Program Files\J-Integra\Exchange\lib\cdo.jar;D:/OracleAS/OracleSOA/jdbc/lib/ojd
bc14dms.jar; D:/OracleAS/OracleSOA/portal/jlib/pdkjava.jar; D:/OracleAS/OracleSO
A/portal/jlib/ptlshare.jar;
3. When i run the command its giving me ClassDefFoundErrro error:-
C:\>java oracle.portal.provider.v2.preference.MigrationTool -mode filetofile -pr
ef1UseHashing true -pref1RootDirectory D:/OracleAS/OracleSOA/portal/portletdata/
tools/omniPortlet -pref2RootDirectory D:/temp/omni
Exception in thread "main" java.lang.NoClassDefFoundError: oracle/portal/provide
r/v2/preference/MigrationTool
I have also run above command in this way but its also not worked for me:-
set classpath=D:/OracleAS/OracleSOA/jdbc/lib/ojdbc14dms.jar; D:/OracleAS/OracleSOA/portal/jlib/pdkjava.jar; D:/OracleAS/OracleSOA/portal/jlib/ptlshare.jar
java oracle.portal.provider.v2.preference.MigrationTool -mode filetofile -pref1UseHashing true -pref1RootDirectory D:/OracleAS/OracleSOA/portal/portletdata/tools/omniPortlet -pref2RootDirectory D:/temp/omni
Kindly do let me know what is the issue?
2ndly, i copied omni portlet preferences (without running above tool) and pasted in UAT environment, OC4J is throwing following exceptions when i called them from Portal:-

I have also changed the connection.xml to point to some stagin server URL where these omni portlets are running but having same exception. What can be the issue?
Thanks in advance.
Regards,

This issue is related to the Shared library in th server.xml. I also had the same issue. the import for oracle.http.client shared library would be missing in your oracle.wsrp shared lib description.
Update that and you will be free of this error

Portlet Preferences Gateway Issue

I have a custom portlet, I am setting 2 custom preferences:
PortletResponse.SetSettingValue(SettingType.Admin,"URL", TextBox1.Text);PortletResponse.SetSettingValue(SettingType.Admin,"Count",TextBox2.Text);These settings basically Set the URL and Site Count for a List. I have built this using the Plumtre EDK, and .net.I have a remote Server, IE not in the same Domain as the corporate portal server. The Preference work great. The portlets render fine everything is wonderful.When I place the code on our Production environment, the initial preference page loads with the gateway, but during postback where I am setting the Preferences above, I get a Gateway exception error. When I look at the URL of the preferences I do indeed see a 'Local' non gatewayed server in the URL. (When I use a server not on our Domain the preference are gatewayed." Has anyone run into this before..I haven't seen it, bugging me!

Store defaul portlet preferences

Hi,
I want to implement edit mode for my portlet, where only admins have access. On the edit page, I want to enable the admins to set the default portlet preferences (the same value for all users, not only for the current user)
How can I best do this. We are using 8.1.5.
I have tried to use the PreferencePersistenceManager looked up with PortalBeanManager (similar as in VisitorTools) but I got a NameNotFoundException

Real brain bender: virtual host or omni portlet issue? Take the challenge

We are having problems with a portal page that displays several omni portlets on several tabs. Here's the situation:
The page consists of 5 tabs, each representing a different demographic characteristic. On each tab there are four omni portlets. One omni porlet represents a selection list. The user makes a selection, which triggers an omni portlet event to pass the selection criteria to a page parameter. The other three omni portlets on the tab read the parameter value and retrieve data according to the selected parameter value.
Example: The user selects the Age tab and selects the link representing data for the Central Region. The omni portlet's event populates the page's "region" parameter with the value "Central." The other three portlets on the tab retrieve their respective data where region = 'Central'.
Since all the tabs on the page represent different demographic characteristics, the omni portlets on all the other tabs also perform their queries where region='Central' so that the user will see Central Region data displayed regardless of what tab they navigate to.
Also, when the user navigates to another tab and selects a different region, all the omni portlets on all the tabs perform their respective queries to capture data where region=<selected region>.
The page performs correctly until we configure a virtual host. In that case, when a user makes a selection of a particular county in one tab, the queries are performed but the page displays with a tab in view other than the one where the user made the selection.
Example: the user navigates to the Age tab and selects region='Central'. Then the user navigates to Gender tab and then Living Situation tab, viewing the results on each tab. Now the user returns to Gender tab and selects region='Western.' The portlets perform their queries and the page re-displays with the user on Living Situations tab, rather than Gender tab where the selection was made.
Obviously, we want the user to stay put on the tab in which they make their selection. I think it's a problem with the virtual host configuration. My DBA thinks it's a problem with the way the page is built. Has anyone else run into this kind of thing? Is there a trick to using Virtual Hosts?

Your main.cf seems redundant.
For example:
if you specify:
virtual_alias_maps = hash:/etc/postfix/virtual_alias, mysql:/etc/postfix/mysql_virtual_forwards.cf
you don't need this:
alias_maps = hash:/etc/postfix/aliases
and i think you have a lot of more options you don't need.
This is my main.cf on my vps and everything works great (sending and receiving emails from/to most common mail server: gmail, hotmail etc etc)
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
readme_directory = no
# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
message_size_limit = 4194304
virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf
virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf
virtual_transport = dovecot
dovecot_destination_recipient_limit = 1
it is very simple (no dkim, no forced tls, no mailbox limits and so on) and it can be improved but it works..
as I suggested you just try spending some hour wiping postfix installation and giving a look to this guide

Portlet not available error when customizing Omni Portlet

Any suggestions are greatly appreciated. Note that I have the same problem with different portlets, so it has nothing to do with this specific OMNI portlet I guess.

Maximum Fields in Omni Portlet?

We have recently installed PDK Release 2 v9.0.2.6.2 and are busy adding Omni Portlets to our Portals. We are really pleased with the majority of functions so far but have now hit a problem.
I seem unable to create a report that displays more than 5 columns. I have tried various different SQL statements that all return more than 5 rows, but I only seem to be able to display 5 columns.
Any ideas?
Thanks,
Paul.

To clarify this issue I have provided a step by step example of my problem below
1)Create blank page
2)Add new omni portlet
3)Select database connection to IASDB or any other valid connection
3)Define omni portlet with the following SQL:
SELECT 'Text 1' column1,
'Text 2' column2,
'Text 3' column3,
'Text 4' column4,
'Text 5' column5,
'Text 6' column6,
'Text 7' column7
FROM dual
4)Click on finish
5)Omni Portlet only displays columns 1-5
6)Edit defaults of omni portlet and on click on layout tab
7)Under the "Column Layout" heading there are only options to display and modify 5 fields and no option to display all 7 fields returned by my SQL query.
My question is how can I display all 7 fields in the SQL that defines the omni portlet?
Thanks,
Paul.

Filter omni portlet output data according to portal user

We have created an omniportlet that connects to a database, and retrives some values into a defined HTML layout.
We want to filter output data according to our portal current user name
When we try to use portal.wwctx_api.get_user inside of omni portlet select statement fallowing error occurs.
Error in executing Query : [ORA-06510: PL/SQL: unhandled user-defined exception ORA-06512: at "PORTAL.WWCTX_SSO", line 1803 ORA-06510: PL/SQL: unhandled user-defined exception ORA-06512: at "PORTAL.WWCTX_SSO", line 1637 ORA-06502: PL/SQL: numeric or value error ORA-06512: at "PORTAL.WWCTX_SSO", line 1865 ORA-06512: at "PORTAL.WWCTX_API", line 183 ]
Thanks a lot

This is because the Omniportlet is actually operating within a different context--a separate database connection from the Portal connection. We have similar issues with Java portlets. You might try creating a public parameter on the portlet, then mapping that to the system variable USER (done on the Parameters tab of the page where you deploy it--if you don't see a parameters tab, you must enable Parameters and Events at the page group properties level). I haven't tested any of this, but it should get you going in the right direction.

Omni Portlet shows No Listener

We have Portal 10.1.4. When connection to portal are reached at 120 then omni portlet on every page of portal shows "No Listener". Other content still visisble on the pages, only problem with the omni portlets.
What should i do to solve the issue.
Thanks in advance

Solutions is to increase timeout value in provider.xml file in MID_TIER_ORACLE_HOME/j2ee/OC4J_Portal/applications/portalTools/omniPortlet/WEB-INF/providers/omniPortlet. If you change the timeout value, you also need to do the following:
Bounce your middle-tier.
Increase the provider registration Timeout value of the OracleAS Portal instances with which this provider is registered.

168.portal MailViewer Portlet Preferences

I'm trying execute the 168.portal - MailViwer Portlet smple to see how the preferences work with JSR 168. But I don't know how to login to view the output as I don't have any user name and passwords. Can anybody guide me on that? Also let me know if anybody can help in using the Preferences as I'm able to load the default preferences but cannot store the preferences with store() method. It gives me :-
java.lang.UnsupportedOperationException: Can not persist preferences. No backing store configured or deployed, or this portal does not support customization.
Any help in this regard would be highly appreciated!!

Portlet Preferences - Any way to define templates or bulk load ?

Hi,
I have a question regarding portlet preferences. We have need to store metadata
about a portlet and this metadata is the same for all portlets inside the portlet.
As we will have in excess of 300 portlets which is expected to rise to around
2000 - 3000 in the future, it will be incredibly tedious for the portal admin
to create the preferences for each one (for such items as portlet owner, portlet
administrator etc)
Is there a template facility (a bit like user profiles) where we can set up the
definition with fields and values etc, and apply to a portlet. Or failing that
a bulk load capability where we can just populate the DB using the portlet_definition_id
or portlet_instance_id in the preference tables ?
We are on SP2 by the way.
TIA
Martin

Thanks Subbu,
That worked.....can you keep us updated on any movement with the SPI as this is
something that of us very definite importance to us.....
Thanks for the quick response

For some reason in Workshop i dont seem to be able to add preferencesto the portlet
i am creating. For example i create a JSP and then right click 'GeneratePortlet'
and it creates me the .portlet file. But when i try to access the preferences
menu it just gives me 'Remove' and the list is empty. It does not offerthe 'Create'
Option. I must be missing somethingTry dragging "Preference" from the palette.
Also even if we could do it at create time in workshop these will bethe same
for all portlets in the Portal and thus this would need to be doneevery time
manually and that would leave room for mistakes and people missingfields etc.
We are looking at a very large number of portlets...
What would be really nice is to define a 'preferences' property setas user profile
etc and then
just apply it...thus not leaving room for errors etc.....
At this time, the API does not support this scenario. We're considering
an SPI for a future release, and we'll make sure this scenario gets
addressed.

Any thoughts.....?

Martin,
Have you considered specifying preferences for each portlet while
creating the portlet in WLW? The recommended approach is to create
preferences while creating the portlet as the portlet developer ismore
likely to know what preferences are required and the implications.If
the default values entered by the portlet developer are meaningful,
portal admins won't have to change these values.

Locale Based Omni Portlet

Hi,
I am currently developing an application using the Oracle webcenter framework. I wanted to have a locale based Omni Portlet whcih could bring in information from the database according to the locale set.
There are a few more things like moving the portlet direction left to right or changing the keys to arabic ones. Is there any solution that is possible

problem solved. There is a locale variable that one can use. It returns the current locale of the Application Server. The only issue is your application should also be configured to that locale

Sharing portlet preferences among users

Hello,
Is it possible to share portlet preferences among users? So that the
portlet preferences would be stored per portlet instance, and would be
the same for every user?
If this is not possible with Java portlets (JSR-168), can it be done
with other portlet types (JSP portlet, page flow portlet), using the
PortletPreferences API?
The JSR-168 specification says:
"Portlet Specification assumes preference attributes are user specific,
it does not make any provision at API level or at semantic level for
sharing preference attributes among users. If a portal/portlet-container
implementation provides an extension mechanism for sharing preference
attributes, it should be well documented how the sharing of preference
attributes works."

Betsy,
Does WLP provide a way to allow a user to store only a subset of all
his portlet preferences (using only JSR 168 api) ?
My aim is to try to create a JSR 168 compliant portlet where few of
the preferences are allowed to modified by the user (in the edit
mode), while all other preferences may be modified only by a portal
admin (thru admin view). However, the PortletPreferences.store()
method seems to store values of all current preferences for the
particular user, with the result that future changes by the admin are
not reflected for any user who has already customized his
preferences.You can let the admin propagate changes to the user via admin tools.
There is an option in admin tools to do that.
Setting the preference <read-only> attribute to 'true' does not help
either, as the store method still attempts to store the value and
then throws a ReadOnlyException.In this case, the setValue/setValues/reset and not the store will throw
the ReadOnlyException.
Why does WLP attempt to store all preference values; as opposed to
setting only those which have been explicitly set using
PortletPreferences.setValue(key, value)?The implementation does not keep track of changes explicitly in memory.
Even if it keeps track of changes, I'm not sure if this would solve your
use case.
Will BEA be changing this in future releases, and is there a
work-around for now?The suggested approach is to let admins propagate changes to users.
Subbu
>
Thanks, Betsy
Although WLP does not support the notion of sharing preferences,
WLP lets you manage preferences in a hierarchy via the admin tools.
When an admin sets preferences on a portlet, as long as users don't
customize their portlets, all users get the same portlet instances,
and hence share preferences.

Accessing 8.1 portlet preferences from PageFlow Controllers

How does one access portlet preference values from within pageflow
controllers?
Having all the JSP tags available is great, but developers need equivalent
functionality made available from within pageflow code!

You could also use PortletPresentationContenxt.getPreferences(request) from

You can access PortletBackingContext from within controllers. You can

Problem pl/sql function as web service in OAS as omni portlet

Dear All,
I try to use pl/sql function from package as web service in OAS as omni portlet. This function returning, for example, the result of searching as number of rows (Id, name).
As I have understood, OAS omni portlets understands only J2EE 1.3(oracle) web service (which is chosen on the first step of the making the service from PL/SQL). Since in the event of choice J2EE 1.3(JAX-PRC) OAS can not analyse the answer SOAP on elements.
I try return types:
1. xml. Kind of <rowset><row><id>1</id><name>John</name></row><rowset>.
2. ref cursor can`t use
3. varray of records can`t use.
At the best, answer recognizes as line, rather then as array element.
Thank you in advance for answer

Replacing library with template deletes portlet preferences

Hi,
If I have to deploy a new version of our portal, with changes to the
.portal file I have to make a dummy desktop from the .portal file, and
then say yes to replace library with template. If I do this however all
my portlet preferences are resat to their default values. Are there
anyway to avoid this, or another way to get the library updated with the
newest version, without having to make a dummy desktop.

my portlet preferences are resat to their default values. Are there
anyway to avoid this, or another way to get the library updated with the
newest version, without having to make a dummy desktop.
