Recommend way to replace doJoin

I have nested TiledViews. In NetDynamics the Data Objects that
populated their fields were joined using the doJoin method. What
is the recommended way of getting this same behavior in JATO 1.2.x?
I have been trying, with little success, to get the values from the
parent TiledView's Model and set them as where-criteria for the child
TiledView's Model.
Thanks,
paul
code from ND:
CSpDataDrivenVisual CSpDDV =(CSpDataDrivenVisual) event.getSource();
return(CSpDDV.doJoin(event.getRowIndex()));

I'm happy to here you were able to diagnose the problem.
I did a prototype app that had 3 nested tiled views and got it working,
albeit, my sample requirements were not as demanding as yours (specific
db logins and such), but I learned one thing.
I found it easier to push the key value down to the child tiledview than
getting it from the parent tiledview. But sounds like no need to pursue
anymore.
good work

I wasn't setting the user and password for the model in the
beginDisplay event, I was setting in on the next and previous, etc
(see below for why).
You were a great help though. I had been trying to get the where
criteria values from the tiled view parent's model and that was not
working well for me, getting them from the page elements is working
great.

Actually that pretty much sums up the advice I have given.
Paul, I think we must be missing something that is going on in your app
that is preventing you from getting the results that are expected.
Tell me, does each TiledView use a different Model class or do they use
the same Model class?
Anything else that you can tell us?

I think Craig is getting back to you with a better answer, but from a
cursory look at your message, you need to execute each TiledView's
model in
its beginDisplay() method (or beginComponentDisplay() for JATO
2.0). Are
you doing this? In other words, each model needs to be re-executed
for each
display of the TiledView.

Craig,
Thanks for the help. I am doing this, but I'm still having problems.
I have three TiledViews on the page:
Survey
|----Questions
|----Display
I'm attempting to illustrate the way they are nested here. It seems
that the models, primary and not, are all executing on the
BeginDisplay event of the page. They execute a second time after I
set the where criteria, but it looks like the fields are already
bound
by the time the criteria is set. Also, the primary model for the
Survey TiledView is executing on the next web action. I should also
note that I have to change the defaultConnectionUser and
defaultConnectionPassword on the model before I call handleWebAction
on the repeated object; this is because there is a view in use that
is specific to the username supplied when logging in, and if I don't
change the user name the view contains no data.
The first time in the page the Survey TiledView is displayed,but the
two nested TiledViews are not; beginDisplay is called on Questions,
but NextTile returns false. When I click next, the first record is
again displayed and the correct data for Questions and Display.
However, a second click of the next button displays the sameresults.
A click on the Last button displays correct results for the last
record.
Any ideas where to look or what to look for would be appreciated.
Thanks,
paul

Paul,
This feature of ND is not built into JATO. It was a somewhatmysterious
feature in ND. I remember it being one of the most difficult
topics
to
explain how ND made it work in my ND developer classes so it
is not
surprising that you are having issues implementing it on your own.
But the solution should end up being quite simple. We just need tomimic
what the ND framework was doing and use a bit of the JATO
framework
to
help us as well. Nested tiled views can be a bit sticky to
grasp as
well.
I don't know what your code looks like, but here is basically whatyou
should be doing. Assume CustomerListTiledView (outer) and
OrderListTiledView (inner) are the TiledView names and
CustomerListTiledView has fields CustNum and CustName, and
OrderListTiledView has OrderID, and OrderDate.
And CustomerListTiledView uses CustomerModel that has model fields
CustNum and CustName, and OrderlistTiledView uses OrderModel andhas
model fields OrderID, CustNum, and OrderDate.
I will assume that your outer TiledView is not a problem and thatthe
issue is with the inner.
In CustomerListTiledView's nextTile method (ND analog to
onBeforeRowDisplayEvent), you want to get the value of the CustNumfield
for that tile, getDisplayFieldValue("CustNum"), and use it ascriteria
for the OrderListTiledView's primary model (OrderModel). But don't
forget to clear the criteria first.
in nextTile method:
TiledView tv = (TiledView)getChild("OrderListTiledView");
SelectModel model = (SelectModel)tv.getPrimaryModel();
model.clearUserWhereCriteria();
model.addUserWhereCriterion("CustNum", getDisplayFieldValue("CustNum"));
The auto retrieve for the OrderModel in the inner tiled view will
execute it with the provided criteria on each row of the outer
tiled
view.
If this is what you are doing, show me the relevant code (noattachments
work on the group, just inline in email) and maybe I can spot thetrouble.

Is there an automated way to replace a query with another in a workbook?

Hi all,
I have a bunch of Queries which I'm planning to phase out, and I have replacement Queries for them. The Queries to be phased out are used in Workbooks. Is there an automated way to replace these obsolete Queries with new Queries in these workbooks? Maybe a BAPI, function module, VB Macro, Tcode (so that a BDC program can be written) or some other way?
Thanks in advance

Kernel seeds are an excellent way to learn how to build a targeted kernel for your hardware, and I use and recommend them. They are not an automated method, which is what I understand the OP is looking for.
(edit) yes, the information on the page is a little dated, but the methods still work. Kernel seeds are not really about faster and easier -- it's about understanding what you really need and how the process works (again, not really what the OP was asking for, but a different approach to kernel building).

Is there a way to replace re-sized images?

I have several images (640 x 480) that I have placed into a PDF. When I use the Object TouchUp Tool, (right-click and choose "Place Image...") they come in WAY too big for the layout, so I scale them down to fit. Now, I need to replace those images with new ones (also 640 x 480).
1) Is there a way to replace the images, (Right-Click on the image to be replaced > "Place Image...") so that the new images are placed at the same dimensions (and hopefully position) as the scaled old images, instead of having them come in HUGE again and manually scaling them down and re-positioning them?
2) Or, at least, is there a preference dialog somewhere that I can define a specific dimensions for the images to be imported at, regardless of their resolution outside of acrobat.
I realize I could create smaller thumbnails and place those in the PDF instead. However, the person who will be responsible for replacing the images isn't very computer savvy, and it would take longer for them to save thumbnails then to just place the image directly into Acrobat and scale them down.

I want to AVOID scaling the new pictures (and in an ideal world, I'd also like to avoid re-positioning) manually. Example, I have a window sticker PDF for a silver car with 3 pictures in it, a front, rear, and interior. When initially placed into the PDF, the pics (640 x 480)for the car were too big for the layout, so I used the Object TouchUp Tool in Acrobat 8 Pro to scale them down to about 150 px wide and position them correctly. Now, we get a new car in. It's practically the same car, but blue. So, the most efficient way to create a new pdf window sticker for the blue car would be to save a copy of the silver PDF and then just replace the silver pics with blue ones.
Practically every other graphical Adobe program on the planet has a way to "replace" or "update" raster images. In my Acrobat 8 Pro travels, it doesn't seem there is a way to do this. I can "replace" (overwrite) the old silver pictures by selecting a pic with the Object TouchUp Tool, then right-click "Place Image..." This will stick the new blue photo in the same position as the old one. However, it still imports in at the giant 640x480 size, instead of the scaled-down 150 px wide size. So, I still need to manually scale the new blue photo down.
Also, I've tried every combination of SHIFT, ALT, CTRL clicking to try to scale the pic from its center. In other words, if I grab the lower-right handle of the pic, the anchor point for the scale is the upper-left corner of the pic... so scaling it like this throws the pic out of position anyway.
So, if anyone has a way to scale a pic from it's center, instead of the corners, please post it!! Even if I could get a dialog box requiring specific numeric dimensions... that would be preferable to having to re-size and manually nudge and smush the pics around to a rough eyeball location every time I need to make a new window sticker for a car (which is a lot)
Cheers!

What is the recommended way to launch a web-start enabled Java application?

Hello,
I have a simple web-start enabled Java application, which I can launch from a brower by entering :
https://xx.xx.x.xxx/MyApp/launch.html
This method would show me a page. I then had to click on a link to run my application.
I noticed that I could also launch my program by entering :
https://xx.xx.x.xxx/MyApp/launch.jnlp
This method would run my application right away.
I wonder if there is a recommended way to launch/run a web-start enabled Java application?
Thank you,

What is the recommended way to migrate a RH8 project to another PC?

I am hoping to get advice on the recommended way to migrate a RH8 project to another PC – the project has been upgraded from earlier version of RH and other users and appears to be carrying a lot of baggage (strange and exotic files). I looked for an “export” function but failed to see any guidance on this in the forums. Hope you can help.

Zip the folder on PC1. Copy the zip to PC2. Unzip it.
Any tidying up has to be done manually. See Reports > Unused Files.

What is the recommended way to upgrade system ruby and python binaries and their libraries?

Hi Sogaard,
see below:
How does SAP recommend to integrate Webi-report in the SAP Portal? Is it through an URL iview, the iview templates (thumbnail, folder and alert) or through the Master Iview?
The sample iViews are just samples for a particular case. The iView template allows you to use any application on the BusinessObjects system - including the viewing of content. What you are looking for is the creation process for WebI. So you have 2 options: you can use the KM integration and you can build a java application that offers the workflow you looking for and integrate it with the iView template
Depending on what method should be used, I'd like to know which settings to be focused on. For instance, if the Master Iview is to be used, should opendocument be used instead of reports? And what other customizations will have to be done in order to integrate a Webi-report instead of a Crystal-Report?
OpenDocument is for viewing reports. The Installation Guide outlines the integration of the iView template and the KM part.
What is the intended use for the BOBJ repositoy manager? Would that be the way to integrate the Info-view?
This is the integration into the KM repository which provides a richer functionality then just an iView.

What is the recommended way for persisting JMS messages?

What is the recommended way for persisting JMS messages?. As per the IMQ admin documentation , using the default built-in persistence type which is through unix flat files is much efficient and faster, compared to the database persistence .
Tried setting up the jdbc stuff for database persistence on iAS 6.5 . I am getting the following
error .

Any thoughts?

From the output, you are using imq 2.0. In that release
the key used to persist a durable subscriber in the database
table has a limit of 100 characters. The output shows that
your value is:

esponse%2C+JMQDestinationDescription%3DA+Description+for+the+Destination+Object%7D:
which is much longer than 100 characters.
You might want to shorten the string you use for the
durable name.
And yes, the default file-based persistence store is
more efficient when compared to the plugged-in persistence
through a database.

What is the recommended way to truncate tables in ODI?

I want to create a separate step to truncate the result tables, before the start of the actual job. What is the recommended way of doing this?
I am currently putting the truncate statements in the ODI procedure, but that has a lot of typing. Is there a odi command in the toolbox that I can use?
Thanks.

Ok,
If the table will be loaded by interfaces, you have the "Truncate" option at the IKM's, just change it to "Yes".
If you need to Truncate but they won't be loaded by Interfaces a possible way is:
- requirements: it will be necessary to have some common "string" at tables names.
1) create a procedure
2) create an step
3) at source tab put:
Select table_name from user_tables where table_name in '%THE_STRING%'
4) at target tab put:
Truncate table #table_name
If you don't have a common "string" you, instead, can create a table with all table names that you need to truncate and change the select command at 3).
Does it help you?

What is the recommended way of connecting to repository out of WebDAV, RMI, JNDI and JCA connector ?

What is the recommended way of connecting to repository out of WebDAV, RMI, JNDI, and JCA connector possibilities provided by CQ 5.5?

Hi dp_adusumalli,
I recognized your list of ~8 questions you posted at around the same time, as I received that same list in our customer implementation from Arif A., from the India team, visiting San Jose. :-)
I provided him feedback for most of the questions, so please check back with Arif for that info.
For this particular question, can you provide specifics for the types of interactions you are interested in?
Understanding the kinds of things you need to achieve will help determine which of the CQ/CRX interfaces is best suited for the task(s).
I've collated a few points on this subject on this page:

Recommended way to secure my TCP/IP Communication

This may be basic, sorry, but I never had to worry about this.
What is the recommended way to secure my TCP/IP communication?
I will have a simple server listening on a TCP socket and servicing client requests. Unfortunately, the server must run at a site only accessible to the client via the internet. The client is a .NET (C#) application. Typically, I'd connect the 2 easily with standard sockets and be done. In this case, I must protect the information being transfered.
What would you use? SSL? I am not too familiar on how to do this on the .NET end.

A common way to secure communications over TCP is SSL, yes. If your question is "How do use SSL in my .NET client?" then perhaps you should seek a more appropriate forum.

Recommended way to end a parse ?

In cases where a XML stream is being read from a file, it is
fairly simple to have the parse end when the end of the file has
been detected. When parsers are used with other streams like
those from a servlet request, it is not as clear when the stream
ends - this leads to the parser waiting for more input from the
stream when there is none..
What is the recommended way of ending the parse of a document if
the ending can be detected by the DocumentHandler ? One approach
that I've used (somewhat unsuccesfully with the Oracle Parser) is
to throw a specific type of exception from the endElement() call
and checking for this exception in the method that initiated the
parse.
The Lark XML parser allow every doETag, doSTag etc method to
return a boolean value indicating if the parse needs to be ended
at that point - what is the SAX equivalent for this functionality
null

Well, unfortunately, it's kind of a mixed bag... Some of the items in there can be quite machine specific, others (say some of the network settings) can be more "generally useful".
System Image Utility makes no effort to clean up this directory which, as you noted, can cause some issues with port mappings... but allows some other things to work transparently.

Recommended way of getting entity manager from pojo class

Hi,
In our application we have the need or retrieving entity manager from 'pojo' classes.
More specifically we have singleton classes which act as 'data' repositories and are accessed from both servlets and ejb.
I'm aware that the repositories classes might be problematic, but in the current stage we can't perform significant change in application structure so I am looking for a 'fast' solution as possible.
The best way will be to lookup entityt manager in JNDI, but as I undestand this feature is not avaialabe in weblogic.
I understand that the preffered way for getting entity manager in such situation is by using @PersistenceUnit annotion on the calling location and lookup entityManager by that name in the pojo. This is however problematic for us since since we access the repositories from variouse locations (many different classes).
Possible additional solutions we thought of:
- creating an 'entity manager factory' locator ejb. This is an ejb with no transaction attribute, which has one method getEntityManagerFactory. It injects entityManagerFactory and returns it. This is the fastest soltion to implement. Is this a valid one?
- using application managed entity manager in such situations. We have a problem doing so now because the creation seems to fail for variouse reasons.
What is the recommended way?
Thanks.

To obtain an EntityManager instance, first must obtain an EntityManagerFactory instance by injecting it into the application component by means of the javax.persistence.PersistenceUnit annotation:
@PersistenceUnit
EntityManagerFactory emf;
Then, obtain an EntityManager from the EntityManagerFactory instance:
EntityManager em = emf.createEntityManager();

HOW TO REPLACE SAFARI BOOKMARKS IN ICLOUD
Turn off iCloud for Safari on all devices including the Mac that will be used to house the bookmarks you want to keep. On your iDevices, if it asks to delete bookmarks, choose YES.
On the Mac, clean up bookmarks using the Edit feature. When finished, copy (do not move) the bookmarks file in the Safari folder in the library (Bookmarks.plist) to a safe location. You will be copying the file back shortly.
Turn on iCloud for Safari on the Mac only. Now manually delete all the bookmarks. This will make iCloud “think” you want these changes to be stored in iCloud and because the other iDevices are have iCloud turned off, they won’t keep “feeding” iCloud with your “old” bookmarks. When you are done, there are now there are no more bookmarks stored in iCloud.
You may want to also manually delete any bookmarks from the Favorites Bar also so that everything is cleaned out.
Now turn off iCloud for Safari on the Mac.
Copy your cleaned up Bookmarks.plist back into the library.
Turn on iCloud for Safari on the Mac.
Your cleaned up bookmarks will now load into iCloud.
When everything looks good, turn iCloud for Safari back on in your iDevices.

Recommended way to start db on oracle10g asm in cluster

We have a oracle 10g asm instance running on Solaris 10 cluster. During maintenance activity, we shutdown the database using cluster but startup of the database is carried out by DBA & not thru cluster. We then start the cluster service of the database after the manual startup. Is this fine & we can continue this practise or the recommended way is to start db thru cluster?

you can enable the database to startup automatically and test it by adding the asm database in the Oracle Clusterware.
