Tag attempted to define a bean which already exists

I am having problems with something i thought was solved in version 10.1.3.0.0, but obviously not.
Here is the error message i get:

OracleJSP: oracle.jsp.parse.JspParseException: /html/portlet/journal_content/view.jsp: Line # 101, </liferay-portlet:renderURL>
Error: Tag attempted to define a bean which already exists: portletURL
I have tried adding init-param forgive_dup_dir_attr to the jsp servlet, but it doesn't help.
Any ideas how to solve this??

Include file causes redefinition of bean which already exists!!

hi,
i have a jsp page in which i have 3 directives include.
in every included file i have the same bean used like that:
<jsp:usebean id="myid" class="myclass" scope="session"/>
that causes the following error:
"the tag tried to define a bean which already exists : myid"
(it s in frensh i tried to traduce it)
does someone know how to fix that problem??
thanks in advance!

i have a jsp page in which i have 3 directives include.
in every included file i have the same bean used like that:
<jsp:usebean id="myid" class="myclass" scope="session"/>In one translation unit, the value of the id attribute of "jsp:usebean" must be unique. Duplicate ids found in the same translation unit shall result in a fatal translation error. The jsp page, together with the included files as specified by page directive "include" recursively, is considered inside one translation unit.
Removing that line in your included files will fix the problem. Of course, you need to include that line exactly once in the including page.

Survey input into a list which already exists?

Can you have a survey populate specific items in a list which already exists?
Example List Columns:
Title
Number
Date
Survey Result A (this is entered by a survey)
Survey Result B (this is entered by the same survey)
Also, can surveys be completed by people who do not have permissions to the site?
Thanks!

can surveys be completed by people who do not have permissions to the site?
>> Yes, But user need permission on survey which will be uniquely configured by breaking permission inheritance
>> User need to provide exactly url of survey response so that they can bypass the site

How can I login to iTunes for the first time with apple ID which already exists, without my credit card

I`ve got an appleID. And now I want to enter iTunes Store. But it asks me to write my credit card number(Visa/MasterCard/Amex) But I don`t have such a card. So I can`t log in. How can I log in without this card???

Hi 6323540,
In order to use an Apple ID without a credit card in the iTunes store, you will want to change the payment information associated with that Apple ID. See the guidelines in this article -
Change or remove your payment information from your iTunes Store account (Apple ID)
http://support.apple.com/kb/HT1918
If you have not yet created an Apple ID and went to create one without a credit card, follow the steps in this article -

Device ID already exists - ISE1.3 issue

Hi ,
Anyone can help guide me. How to solve this issue.
My authorization rules allow ONLY Registered Device to access. During the testing I deleted a client's MAC from Endpoint Identity Group List > RegisteredDevices. Then I try to register the device again through My Devices portal. Error show "Device ID already exists".
I try to find out from the document but it's not much help. The document is not clear. It said
Errors When Adding Devices to My Devices Portal
Employees cannot add a device, if another employee has previously added it such that the device already exists in the Cisco ISE endpoints database.
If employees attempt to add a device that already exists in the Cisco ISE database:
   •   And it supports native supplicant provisioning, we recommend adding the device through the BYOD portal. This will overwrite any registration details that were created when it was initially added to the network.
   •   If the device is a MAC Authentication Bypass (MAB) device, such as a printer, then you must resolve ownership of the device first. If appropriate, you can remove the device from the endpoints database using the Admin portal, so that the new owner can successfully add the device using the My Devices portal.
another source from cisco
When I try to add a device, I get an error that says that the device already exists, but I do not see it listed as one of my devices. How can I add this device?
That error means that someone has already added the device to the system. If it does not appear on your list, one of your coworkers has registered the device already.
You have several options for resolving this situation:
   •   If you are attempting to add a device such as a printer, you will need to contact your help desk to locate the current owner and to resolve this issue for you.
   •   Regardless of the device type, you can contact your help desk so that they can verify who registered the device previously and delete it from the database so you can re-register it.
Some source tell me to delete device from My Device portal that was registered. However, the device is not shown there.
Any suggestions are welcome. Thank you.

This happens normally when you register one host against the zlm server, stop zmd, delete the deviceid and secret file, start zmd and register it again against the zlm server without deleting the existing device in the zlm web interface.
What happens at this time is that the zlm client registers with the deviceid and the secret against the zlm server. In the web interface you see the hostname of it. If you open the details, you see the guid of the host which equals the deviceid.
When the zlm client communicates with the zlm server it uses the deviceid and the secret to login and query the bundles, catalogs and policies assigned to it.
So now when the zlm client is stopped, the files deleted, the zlm recreates them the next time it is started. After registering against the zlm server, it tries to login with the new deviceid and the new secret. There is already such a host entry, therefor it renames one and register with the new values again.
Do you have maybe a cron job or something that deletes those files and restarts the zlm client ?

What is the best practice for inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?
>> I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). <<
MERGE statement; Google it. And do not use temp tables.

Error while exporting universe: aux.lov already exists

Hi,
I have created a universe on top of an info cube. I can generate the universe and save it. But when I want to export it to BO server I'll get the following error:
Original error:
"Fehler beim File Repository Server: Ablegen der Datei auf dem Dateiserver fehlgeschlagen: frs://input/a_241/209/000/53745/aux.lov ist bereits vorhanden"
In english:
Error in File Repository Server: Export of universe at the file server failed. frs://input/a_241/209/000/52745/aux.lov already exists".
I don't understand what this error means. Is there a list of values in my universe which already exists???
Is there a solution solving this error?
I would be very glad if someone can give my a hint.
Thanks,
Claudia
Edited by: Claudia Liebl on Dec 1, 2008 3:39 PM

Claudia,
I have had the same error message and I avoided this by disabling the LOV for the object in Universe designer (Object properties).
In SAP based universes, by default every object has a LOV. The names of these LOV are alphabetical. You'll have to find the objects with the LOV starting with au*.lov and then go to the object which has the specific lov you mentioned and disable it.
It is weird that this error happens, though there are 20,000 other objects with LOV's enabled. This to me looks like a bug in SAP based universes.

Error 32812 (Specified Tag Name not Defined) from FP Read

I built an application using LabVIEW 7.1 and FieldPoint 4.1. It
performed well until about a week ago. Suddenly, I started getting
error 32812 (Specified Tag Name Not Defined) when doing an FP Read to
read all the channels on an FP-RLY-420. This is installed at a
client's site, but my client assures me that nothing changed in the
computer configuration. There is a dual serial card installed (SIIG
Cyberserial DualPCI dual 16550
RS232 Serial I/O Card), which does seem to cause problems (mouse jumps
erratically), and I wonder if this card could be contributing to the
problem, but I'm not sure why I would get the specific error message
I'm getting.
In looking for info on the problem, I did find an article on
registering the MIS files, but I have tried selecting "Find Devices"
through MAX while logged on as an admin, and the error still occurs.
If anyone has any ideas as to what could be causing the problem, it would be greatly appreciated.
Thank you,
Jason

Hello Jason,
I think that the error you are seeing could be caused by either 1) a
mismatch between the tag names saved on your computer and the actual
channel names on the module, or 2) a problem with how the serial port
is communicating with the module (only applies if you are using a
serial communication module, as opposed to an Ethernet module).
For the first issue, you have already tried to reconcile any
differences in tag names by reregistering the MIS files. Since
that didn't work, I would recommend trying to recreate your entire
FieldPoint system in Measurement & Automation Explorer (MAX),
including the IAK file. I know it is kind of extreme, but I would
recommend just deleting your FieldPoint configuration in MAX, deleting
the IAK file, and resetting the address and recreating your
configuration.
I think that troubleshooting a serial communication problem could be a
little more difficult. I would recommend browsing through the
following documents for some possible troubleshooting ideas.

Let us know if this solves the problem or if you have any further question.

JSP runtime taglib error: "parent is not defined as bean"

1)what is the reason for this problem
2)in weblogic document they told to edit server.policy file in webligic\lib folder
a)what the modification is needed in this file..?

Hi jerry
i already got that problem solved by removing jaas.jar file
from class path.
i don'nt how it is working with out in classpath...?

Hi Nivas,
I think that the problem you are seeing has something to do with the
placement of jaas.jar in your classpath
On WebLogic server, put jaas.jar in the classpath after weblogic.jar.
I would bet that you have it placed before weblogic.jar right now.
I don't think the exception that you're seeing right now has anything
to do with your weblogic.policy file right now, so I think it is
safe to not worry about it right now.
Hope this helps,

Illegal Operation when attempting to define a DIM Source/Target for Essbase

We have installed the Hyperion DIM adapter and got past errors finding HASClient.dll when starting Designer.
In Workflow we have defined a data source for Essbase. When attempting to define a new source from 'Hyperion Essbase'. The application pops up an error dialogue stating that HASClient.dll has performed an illegal operation.
Have double checked the environment variables and they look OK. Anyone any idea what might have gone wrong? We already have Hyperion Planning adapters running fine, it's just the Essbase adapters giving problems.

We solved the problem by reviewing and correcting some environment variables that had been wrongly adjusted on previous product installs.
We stripped back the environment variables and then built new ones in line with the [DIM 11.1.1.2 Installation Instructions|http://download.oracle.com/docs/cd/E17236_01/epm.1112/dim_11111_install.pdf]
