How to deal with conflict and potential conflict classes?

Some classes are marked as conflict and potential conflict classes in the Classloader Analysis Tool.
How to deal with them?
How to use suggested solutions?

Not double load them.
Conflicting classes can lead to weird exceptions. One obvious example would be if you package
an older servlet.jar version into your application and use the weblogic classloading features, such
as prefer-web-inf-classes, to tell weblogic to use this class instead of the one provided in the
system classpath. This one example which leads to weird exceptions, such as connot process jsp tag...
If you really need a the version of the jar for your application, you have to test it through and through
so that you know you do not run into weird production errors.

How to deal with "Error 1001. The specified service already exists" when install a service using installer package?

Hi everybody,
I wrote a "Class Library" project which is a service using Visual Stodio 2008 recently, then tried to use a Visual Studio 2008
Setup Project to install it.
Here is what I did for the "Class Library":
1. Finish the program.cs, Service.cs
2. Add Installer
3. Change the serviceInstaller so that "StartType" to be Aotumatic
4. Change the ServiceProcessInstaller2 so that "Account" to be LocalSystem
5.
6. Click in F5 (Start Debugging)
Here is what I did for the Setup Project:
1. Add the exe file built from the "Class Library" project to the Application Folder
2. On the Custom Action Editor, add the exe file from 1 to Install and Commit
3. Change the property of the project so that "RemovePreviousVersion" to be true
4. Click on F6(Build Solution)
Then I tried to run the msi file from the built of the Setup Project. Because I modified the two projects serveral times, I uninstalled the Class Library using "Control Panel->Add or Remove Programs" before I reinstall. Two things I notived:
1. After unstall, the registry was not cleaned up about the installed program
2. After several rounds install/uninstall, I got "Error 1001. The specified service already exists"
My questions are:
1. How to cleanup the registry when uninstall a program?
2. How to deal with the "Error 1001. The specified service already exists"?
3. Did I do anytbing wrong with the "Class Library" or the "Setup Project"?
Thanks a lot!

Hi Simon, not a problem!
I spent some more time on this and here are few more notes:
it is called Major Upgrade, when you are installing new version of the product upon a previous one and
MSI supports 2 strategies:
Strategy 1. Install a new version and uninstall previous one. (Install a new version right upon previously installed version (file merging is performed based on dll version number) and the delete previously
installed files)
Strategy 2. Uninstall previous version and install a new one (Delete all previous files and install from scratch new files.)
From the first look it seems that 1st strategy is weird and buggy. But, remember, MSI is great because it's transactional!!! That means that if once some of the phases (Installation, Uninstallation, Rollback, Comit) fails, your machine
will be reverted to the previous state and it'll be still functional.
Let's consider both strategies:
Consider you have installed product_v1.msi and you want to install product_v2.msi.
Strategy 1
1. MSI engine copies files from Product_v1 directory to TEMP directory
2. MSI engine merges files based on the assembly version (between v1 and v2)
3. Once merging is completed successfully it removes files in TEMP (RemoveExistingProducts action triggers it) and you got product_v2 installed, otherwise if it fails MSI engine revert machine to V1 and copies previous files from TEMP.
Strategy 2
1. MSI engine tottaly removes all files from v1.
2. MSI engine installs v2 files and if something goes wrong you cannot revert back, because RemoveExistingProducts allready worked out and MSI doesn't have files to revert machine back
I recommend to everybody to use Strategy 1 and leverage MSI transaction functionality. And you can set this strategies by defining sequence of RemoveExistingProducts action. See more info
here. So, I think it's not even a bug in VS as I said in the upper post it is default recommened behaviour.
AND, you got "Error 1001. The specified service already exists"
because if we follow Strategy 1 MSI engine tries to install Windows Service on top of the existing service and OF COURSE it fails MSI engine (StopServices, DeleteServices actions are executed before actual
installation and they look at ServiceControl table). In order to stop service first and delete them you have to fill ServiceContol table of the MSI (and then StopServices, DeleteServices actions will recognize what to they have to stop
and delete), like this:
*clip*clip*clip*
' see http://msdn.microsoft.com/en-us/library/windows/desktop/aa371634(v=vs.85).aspx for more info
' Update the Service Entry to stop and delete service while uninstalling
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD_Service', 'Service name', '160', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
' Update the Service Entry to stop and delete service while installing
query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD2_Service', 'Service name', '10', '', '1', '"
+ componentName + "')"
Set view = database.OpenView(query)
: CheckError
view.Execute : CheckError
*clip*clip*clip*
We can uninstall service first by following Strategy 2, but then we lose transactional support.
So, Simon did I encourage you to change your code a bit?:)
And, btw, if you don't want to change the strategy, please don't rely on SequenceID in MSI table, it can be change, you have to get the at the runtime.
Hope it will help to everybody!

How to deal with this problem?

How to deal with this problem?
We plan to use Oracle Coherence (In Memory Data Grid) for a large-scale application. In order to keep the database table data in Coherence caches, we will create all the corresplonding Java objects (entities) and construct the persistence system using JPA/EclipseLink+JDBC. In this way, any in-memory object update will be persisted to the corresponding database tables.
The problem is that some existing application codes are updating these database tables directly now. If the direct-database-table update is not permmited in the persistence environment, we have to discard most of the existing application scripts.
I want to know, in this situation, should I discard most of the existing scripts?
Are there any other solutions?

Allowing writes from both cache & DB is possible with its own set of issues.
The main issue to consider is conflicts from updates on same record via both cache and DB. If your caches are write-through the conflict decreases - but then cache writes become slower. If your caches are write-behind potentially the older cache update will overwrite the latest DB update. Now you are back to Database 101 -- timestamps, versions, etc...
If you use a DB trigger to initiate the resync request you might want to distinguish whether the update has come from the cache-store (in which case, you may choose to do nothing), or if the update was from the 'existing apps', etc...
If you choose to inject the resync logic at the application code level - you have the usual sourcecode issues - can you modify the code, is all the DB code localized, what options do you have to link with Coherence functionality (DLL, external proc, webservice, etc), etc... Naturally though, if you have to make substantial changes to signal a resync....you might consider taking the extra step and change the code to write to the cache.

it's just few months that I have started to use Java and since, I've been really confused how to use it. As I've been using C++ before, it's really easy for me to handle a few libraries and keywords and write every thing all by my own. But in Java, TOOOO many libraries and keywords all with different procedures and different cases that really bothers me and I can't understand how to deal with all these. As an example, When I just want to start and write a program, I start searching the net and wow. too many different classes and different Keywords that I get too confused and I prefer not to continue. Would someone please help me and tell me how to find a solution for this essential problem???

How to deal with relation

Hi
I am trying to import two beans(TestBean and HelperBean)into my Web Dynpro project to create a model. These beans are dealing with a List(ArrayList). This List is considered as a Relation. I am facing problem in handling this relation.
I am having both the TestBean and HelperBean in the same package. Below is the code of TestBean. This bean is in turn calling HelperBean ,which is returning a List.
I am getting an error while creating model -
[Error]: There are one or more relations unresolved. Importing the model without resolvoing the relations might result in erratic output.
Code For TestBean
public class TestBean implements Serializable{
 private List customerList= null;
 HelperBean helper = new HelperBean();
 public void execute(){
 try{
 customerList = (ArrayList)helper.getCustomerList();
 catch(Exception ex){
 ex.printStackTrace();
 * @return
 public List getCustomerList() {
 return customerList;
 * @param list
 public void setCustomerList(List list) {
 customerList = list;
I am new to Web Dynpro and don't know how to deal with relation.Please inform if there is some solution.
regards,
Sujit

Sujit,
Not every bean becomes model class during import. So your HelperBean is irrelevant here. But you miss other bean, namely Customer bean. You must add it as model class during import, then select problematic 0..n relation and resolve it to model class Customer.

How to deal with deadlock on wwv_flow_data table when http server times out

There are some threads about a deadlock on the wwv_flow_data table. None of them contain a real explanation for this behaviour. In my case I will try to explain what I think is happening. Maybe it helps somebody who is hitting the same matter.
In my case with APEX 3.2.1 I am navigating from one page to another. Doing this APEX will lock the table wwv_flow_data. As soon as the other page is shown the lock will be released. But now this other page contains a bad performing query (standaard report region). After 5 minutes the http server (modplsql) will time out and present the message "No response from the application server" on the screen. In the meanwhile the query is still running on the database server and the lock stays on the wwv_flow_data table.
Normal user behaviour will be that the user will use the back button to return to the previous page and tries it again to navigate to the other page or
the user will try to refresh the page with the bad performing query.
And voila now you will have a deadlock on the wwv_flow_data table since a second session is trying to do the same thing while the first hasn't finished yet.
How to deal with it?
First of all. Have a good look at the bad performing query. Maybe you can improve it that it will succeed before the http server will timeout.
In my case the 11gr1 optimizer couldn't handle a subquery factoring clause in the best way. After changing it back to a classical inline query the problem was solved.
Secondly you could increase the timeout parameter of the http server. Although this not the best way.
Maybe it would better if APEX in a next version would release the lock on the table wwv_flow_date earlier or do a rollback just before the moment that the http server is timing out.

Mathieu Meeuwissen

Hello Shmoove,
I saw your reply here and you probably understand the problems the HTTP 100 response may cause.
I am trying to send image that was taken by getSnapshot. The problem is that the server respond with this HTTP 100 message.
I suspect that the reason that my server doesn't recognize the file that I'm sending from J2me is that the "server to client" response to the 100 message comes after the second message of (see what the TCPIP viewer shows down here):

How to deal with OpenCL grey out issue.

First off, I'm not native english speaker.
I have Nvidia GeForce 550 Ti video card, and its support OpenCL v1.1.
I'm also face a "random" OpenCL grey out issue like other people here, but I found the "issue" and how to deal with.
open a command windows (using WinKey + R, and type cmd <enter>)
type "cd C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)" <enter>
type "sniffer_gpu" <enter> -->> to check your GPU has OpenCL in Photoshop?
When GPU is in power-saving mode (core running in 51Mhz, using MSI Afterburner monitor), I running sniffer_gpu, got this report
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>sniffer_gpu
Device: 0000000000328D68 has video RAM(MB): 1023
Vendor string: NVIDIA Corporation
Renderer string: GeForce GTX 550 Ti/PCIe/SSE2
Version string: 3.0.0
OpenGL version as determined by Extensionator...
OpenGL Version 3.0
Has NPOT support: TRUE
Has Framebuffer Object Extension support: TRUE
OpenGL ok
Return code: 1
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>
No OpenCL support
Then, I switch GPU back to normal status (core running at 900Mhz)
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>sniffer_gpu
Device: 00000000001F8D68 has video RAM(MB): 1023
Vendor string: NVIDIA Corporation
Renderer string: GeForce GTX 550 Ti/PCIe/SSE2
Version string: 3.0.0
OpenGL version as determined by Extensionator...
OpenGL Version 3.0
Has NPOT support: TRUE
Has Framebuffer Object Extension support: TRUE
OpenGL ok
OpenCL ok, version=1.1 CUDA 4.2.1
Return code: 3
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>
OpenCL support !!
Nowadays, most of new GPUs were support power-saving, but when sniffer_gpu running at GPU power-saving state, the OpenCL computing report maybe "time-out", cause the detector "guess" the GPU does not support OpenCL. This is why many people says "OpenCL" sometimes work, sometimes grey-out.
I hope this bug can be fixed, or at least people can understand how to "enable OpenCL everytime when you launch photoshop".
Bye.

How to deal with credentials for external applications using a Java Client/

Hi Guys,
This is the case. I am integrating an external application with an ADF Application. I have implemented some programmatic ViewObjects that are being filled up by a REST Java Client Wrapper. Everything is working fine but the issue is that the credentials the wrapper is using are hard coded inside the java class. I am thinking to ask for the credentials at the beginning of my taskflow and then store them somewhere and use them then to create my client wrapper (passing them in the constructor).
However, I don't know if my approach is good and I would like you to share your experiences or how to deal with this.
Regards

You can use Credential Store Framework to store the credentials securely in the weblogic server instead of hardcoding in the java class.
The Credential Store Framework:
- enables you to manage credentials securely
- provides an API for storage, retrieval, and maintenance of credentials in different back-end repositories
Check the documentation on CSF API -
http://docs.oracle.com/cd/E29505_01/core.1111/e10043/devcsf.htm
Major Steps -
1. Create a credential map and key in em console to store the password (http://docs.oracle.com/cd/E25054_01/core.1111/e10043/csfadmin.htm)
2. Use CSF API to retrieve the stored password
3. In jazn-data.xml give permissions to access CSF key and map

How to deal with payment of vendor to us (credit notes I guess)

Normally I use F07 for outgoing payments, it's linked to vendors, but how to deal with incoming payments of vendors?
We got paid two invoices(credit notes I guess) and I want to put them under the right vendor, but how do I do it?
I can't use F07 I think because I need to use positive amounts (for normal purchase invoices) and can't use negative amounts in this transaction. F08 is for ingoing payment but that session is linked to customers I thought..not for vendors?
How to deal with this kind ot transactions? What transaction can I use the best for payments like this

Hi Kamlesh,
Thanks for your response.
Actually, In the "Process External Bank Statement" window, i see that there are few entries which is for the previous year and which has not been reconciled. I have never worked practically on BRS and hence, i am scared to make any changes in the clients database without being confident on what i am doing. I need to reconcile for one of their Bank a/c for the month of April '08. I have the copy of the statements for the month ending 31st Mar 08 and 30th Apr 08. The closing balances are as below:
31/03/08 - 2300000.00
30/04/08 - 3100000.00
Now my OB for Bank a/c for April '08 in SAP is 2300000.00 Dr.
When i go to External Bank Reconciliation - Selection Criteria Screen (Manual Reconciliation), here are the detail that i enter:
Last Balance: INR -7,000,000.00000 (Grayed out by the system)
Ending Balance: INR -3,100,000.00000 (Entered by me)
End Date: 30/04/08 (Entered by me)
"Reconciliation Bank Statement" Screen opens up and shows the below balances in the screen:
Cleared Book Balance: INR -7,000,000.00000
Statement Ending Balance: INR -3,100,000.00000
Difference: INR 3,800,000.00000
As per the Bank statement, i have found all the transactions listed out here for the month of Apr '08 but, i also found that the open transactions for the previous month from April '08 have been lying in "Process External Bank Statement" window.
Could you please help me solve my issue as to what needs to be done or could you also get me some links from where i can get few documents for processing External Bank Reconciliations?
That will be of a great help for me. I need steps as to what needs to be done first and then the next so that i can arrive at the correct closing balance for the month April '08.
Thanks in Advance....

Organizational unit transfers ,how to deal with the person in it ?

Hi,All,I need your help!
if an organizational unit has been transfered to another upper organizational unit ,and there are already persons assigned to different positions of it,so how to deal with this problem?are those person's IT 0000,0001should be changed too?and how to maintain this kind of change?is a personnel action necessary?or there is some other more efficient way for it?

Hi
In IT0001 You have a Position which is linked to a Org unit. If you want to change the org units reporting relationship then you have to change it in OM by creating a new relationship with the upper org unit.
All the person are assigned to position so nothing needs to be done in PA.

IMac SSD full - how to deal with the two drives

Greetings all,
I've been using an iMac i7 with two drives SSC and HDD. Recently, I've been having issues with the SSD being close to full. I use it for applications only, although some apps need lots of space (iTunes, iMovie, Photoshop, etc.) I use Lightroom and have all the images on the spinning drive. Does anyone know how to deal with this issue? Any way I can move the music from iTunes to the separate drive, or any way to figure out what exactly is using most of my space?

How to deal with the barcode?

i'm developing a file storage system in java, there're two barcode on each file(one is pdf417, the other one is code128) , but now ,there's a problem confused me :
i use the barcode scanner to scan the file and get images of these files from the scanner , but i have no idea how to deal with these images,
i need the barcode information on the images, and i know there're some java components can help me to read the barcode from images , for example : BarcodeReader from Barcode Library, but these components were too expensive for me , is there any other way can solve this problem?

yes, look for a cheaper component...
Or write your own...
Or save up until you can afford the more expensive ones...
