Need help on SOA implementation strategies

I am interested in strategies for implementing SOA using BEA. I figured one would be using WL+ALSB combination, and the other using WL+ALBPM combo (The service is designed in WL). Am I right in my thoughts? Also can anyone please guide me to any article/papers which can compare the two implementations? The points of comparisions that I am interested is ease of orchestrating services, ease of enforcement of SLA & runtime, ease of development and of course SOA Governance issues and the standard NFR's

I think you're going to need to specify more about the requirements of your project. Try starting with the type of PBX, its interconnections and capacity requirements. You might also put some kind of an upper boundary on your budget since 'cost effective' for one company is certainly not so much for another.

Need help on how implement security.

Hello everybody,
I have developed an application with many pages,
It's time now for me to strat working on the security ....
I will have the following :
-Some pages will be accessible by some users but not some others.
-For some reports, there is a column that will be updatable by some users but nor by others.
-The users will be grouped into groups.
I need help on how can I start develop this security model, creating groups perhaps.....
Thanks for any help.

Jina,
Check out Authorization Schemes in the User Guide and under the Security tab in the builder.
Also search this forum for keywords like "security", "authorization", and "groups"... I think you'll get lots of useful threads.

The parameter describtion you show is useless. It tells absolutely nothing about the actual data types used nor how those parameters are exactly supposed to be passed. Show us at least the function prototype too!

Need help: how to implement sun niagara encryption chip with weblogic

Hi all, I have a issue with SSL performance on top of T2000 server, thats why I try to use encryption chip provided by SUN T1 technology, but I couldnt find the implementation document for this technology with weblogic server.
Im using weblogic 9.2MP3 with sun solaris 10. I really appreciate if any body can help me with this problem.
Thanks,

Hello,
How are you obtaining the EntityManager and EntityManagerFactory? If it is injection, you should verify that the second transaction scope gets its own EM/EMF injected rather than being passed the one from the first one.
Best Regards,

Need help in operation implementation

have gone through the CE tutorial page and started building one sample application in CE which will create outbound deliveries in SAP. I am using BAPI_OUTB_DELIVERY_CREATENOREF and BAPI_TRANSACTION_COMMIT to do this job. what i am planning to do here is
- create CAF project in NWDS 7.11
- in the external node import these two BAPIs
- create an application service in modelled node ( with name createobdnsap ).
-using default mapping option create wrapper operation for the two BAPI'S. when i am doing this i have selected the option "create methods in the existing application service". so that two operations will be created in the application service createobdnsap.
- now add another operation createdelivery and check the "manually implement"check box.
- go to .java file of the implementation and call the BAPI_OUTB_DELIVERY_CREATENOREF operation first and then BAPI_TRANSACTION_COMMIT.
i am stuck up in the last step. i am not able figure out the correct java statement to call the BAPI_OUTB_DELIVERY_CREATENOREF and BAPI_TRANSACTION_COMMIT.
it would be great if anybody can give me some insight into it.
thanks

1) When you post code, please use[code] and [/code] tags as described in Formatting tips on the message entry page. It makes it much easier to read.
2) Don't just post a huge pile of code and ask, "How do I make this work?" Ask a specific question, and post just enough code to demonstrate the problem you're having.
3) Don't just write a huge pile of code and then test it. Write a tiny piece, test it. Then write the piece that will work with or use the first piece. Test that by itself--without the first piece. Then put the two together and test that. Only move on to the next step after the current step produces the correct results. Continue this process until you have a complete, working program.

I need help with a textArea which wont implement a JScrollpane

I have created a text area, but when the words get to the bottom there is no scrollbar. I tried implementing the scrollpane to the text area, but it doesnt work. I added it to a panel, then the panel to the frame.
(Here are the snippits of coding that I have)
public class RPS extends JFrame implements ActionListener, ItemListener
JTextArea textDisplay = new JTextArea(50,30);
JScrollPane jscrollpane = new JScrollPane(textDisplay);
//constructor?
public RPS()
///various menu items in here and buttons with action listeners
public void createPanel()
     JPanel outputPanel = new JPanel();
          outputPanel.setLayout(new GridLayout(1,1));
          outputPanel.setBorder(BorderFactory.createTitledBorder("TEXT IN HERE"));
          outputPanel.add(textDisplay);
//further down
          JPanel rightPanel = new JPanel(new GridLayout(3,1));
          JPanel leftPanel = new JPanel(new GridLayout(1,1));
     leftPanel.add(outputPanel);
          add(leftPanel);
          add(rightPanel);
     public static void main(String[] args)
          JFrame frame = new RPS();
          frame.setLayout(new GridLayout(1,2));
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.setVisible(true);
}So what I have is a frame, with two panels. One on the left and one on the right. The textDisplay (text area) is displayed on the outputPanel, which is then added to the left panel, then added to the frame. The right panel is for all the buttons which I left out to keep this simple.
Can anyone help me please? All the other irrelevant coding has been left out.
Need help asap please :( I was sure everything is correct.

you add the textArea to the scrollPane
JScrollPane jscrollpane = new JScrollPane(textDisplay);but then you add (only) the textArea to the panel
outputPanel.add(textDisplay);whereas you should be adding the scrollpane to the panel
outputPanel.add(jscrollpane);

Need help with Business One Implementation Consultant Certification

Hello,
I need help preparing for the B1 certification. I have taken the test once already and failed. I found it very tricky with multiple correct answers for each question.
I have gone thru the eLearning several times now. And this week I am taking the instructor led training. I have also purchased and studied the Ebook. I have a good grasp of the product, but I feel that this is not enough to help prepare for the test.
I want to know if there are any other resources I could use to help prepare for the test. Are there any practice exams
Any and all help is appreciated
Thank you!

Hi John,
I found the e-learning good , but a bit limited, so I branched out to these & passed quite well :
- documentation links on the 2007 landing page:
Channel Partner Portal -> Solutions -> SAP Business One -> Hot Topics -> 2007
- ETS:
Channel Partner Portal -> Solutions -> SAP Business One -> Support -> Training & Knowledge
- DRC:

Need help in building a utility...?

Gurus,
I need to build a dynamic selection screen for a utility that will extract data from a legacy database. I am not sure how to do it....I have the design in mind but will need help from you experts in the implementation.
So i need to have to twol radip buttons on the selection screen such that when one radio button is clicked then few other select options come on the screen and when the other radio button is selected then different select options come on the screen.
Once the user any of these two radio buttons and fill in the respective values for the parameters, then i have to fire native SQL queries on the legacy SQL database.
Any suggestions...
First i need to code the dynamic selection screen ....Your help will be appreciated...

Need help to draw a graph from the output I get with my program please

Hi all,
I please need help with this program, I need to display the amount of money over the years (which the user has to enter via the textfields supplied)
on a graph, I'm not sure what to do further with my program, but I have created a test with a System.out.println() method just to see if I get the correct output and it looks fine.
My question is, how do I get the input that was entered by the user (the initial deposit amount as well as the number of years) and using these to draw up the graph? (I used a button for the user to click after he/she has entered both the deposit and year values to draw the graph but I don't know how to get this to work?)
Please help me.
The output that I got looked liked this: (just for a test!) - basically this kind of output must be shown on the graph...
The initial deposit made was: 200.0
After year: 1        Amount is: 210.00
After year: 2        Amount is: 220.50
After year: 3        Amount is: 231.53
After year: 4        Amount is: 243.10
After year: 5        Amount is: 255.26
After year: 6        Amount is: 268.02
After year: 7        Amount is: 281.42
After year: 8        Amount is: 295.49
After year: 9        Amount is: 310.27
After year: 10        Amount is: 325.78
After year: 11        Amount is: 342.07
After year: 12        Amount is: 359.17
After year: 13        Amount is: 377.13
After year: 14        Amount is: 395.99

The above is also good.Sorry but you need to look a bit more closely at URLs that you cite. What the OP wants is a chart (as in X against Y) not a graph (as in links and nodes) . 'jgraph' deals with links and nodes.
The best free charting library that I know of is JFreeChart from www.jfree.org.
