Developing Portals using JSR Compiant API and struts

Hi,
I am using Oracle AP Portal server 10.1.4 for development and all the existing portals are developed using Oracle PL/SQL. We have to convert all of them into JSR 168 Compliant (JPS API ) portlets using struts framework.
Could you provide us ideas or code snippets or sample applications?
It will be appreciated your responses as soon.
Thanks
Suren

I may end up having to do that, but I'm trying to keep my solution set as it is as I apply a print layout using tiles to each of the reports and I would like to keep things that way if I can.
I just noticed something interesting that I had not seen before, and that is in the PDF there is text rendered for the tiles tag <tiles:getAsString name="title" /> which tells me that the HttpURLConnection is getting the tiles attributes, but where it is failing is on the <tiles:insert attribute="body" /> tag. That at least narrows the problem down to the tiles:insert line specifically and not tiles overall.

Developing portal using Weblogic portal 10.3 or weblogic workshop 10.3

Hello
I am new to portal development. I see that one can develop portal using Oracle weblogic workshop 10.3 which has many features including Java Page Flow and Java controls. I am wondering what extra features one can get using Weblogic portal 10.3. The Weblogic platform 10.3 which I use does not have weblogic portal, it has weblogic AS and workshop. Do I need weblogic portal install now or in future while developing portal. I am trying to develop a portal from scratch. Any input will be highly appreciated. Thanks.

Some suggesssions,
While installing the weblogic you need select weblogic portal option also. Only for weblogic different installation exe file with portal different exe file.
To get the weblogic portal server and portal work shop with weblogc you need to down load weblogic portal 10.3 exe file.
Thanks,

Pull large amounts of data using odata, client API and so takes a long time in project server 2013

We are trying to pull large amounts of data in project server 2013 using both client API and odata calls, but it seem to take a long time. How is this done
In project server 2010 we did this creating SQL views in both the reporting database and for list creating a view in the content database. Our IT dept is saying we can't do this anymore. How does a view in Project database or content database create issues?
As long as we don't add a field in the table. So how's one to do this with creating a view?

Hello,
If you are using Project Server 2013 on premise I would recommend using T-SQL against the dbo. schema in the Project Web Database for your reports, this will be far quicker that the APIs. You can create custom objects in the dbo. schema, see the link below:
https://msdn.microsoft.com/en-us/library/office/ee767687.aspx#pj15_Architecture_DAL
It is not supported to query the SharePoint content database directly with T-SQL or add any custom objects to the content database.

Any one uses javax.print API and works?

I have just downloaded 1.4 beta2 SDK and imported all the javax.print classes. I use the most simple test code as the following:
FileInputStream fis = new FileInputStream("test.txt");
try {
DocFlavor psInFormat = DocFlavor.INPUT_STREAM.TEXT_PLAIN_US_ASCII;
Doc myDoc = new SimpleDoc(fis, psInFormat, null);
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
aset.add(new Copies(1));
aset.add(MediaSizeName.ISO_A4);
aset.add(Sides.ONE_SIDED);
PrintService[] services = PrintServiceLookup.lookupPrintServices(psInFormat, aset);
if (services.length > 0) {
DocPrintJob job = services[0].createPrintJob();
job.print(myDoc, aset);
} catch (Exception e) {System.out.println(e.getMessage());}
However, PrintServiceLookup.lookupPrintServices can't find my printer. I have 9 network printers connected to my system which range from HP LaserJet 4500 to 8100 and Acrobat PDFWriter. The API can't find any of my printer? What did I do wrong

Hi Guys,
First,
If your trying to print any document sent by the server from the client machine u have to write a applet which recieves the output in form of stream and then print it. I could do these with JPEG, GIF and ASCII but could not do it with PDF (The sun doesn't have a implementation for PDF document printing, they just have a declaration may future released will help us print PDF).
If u want the Print dialog box to appear use the following code that worked fine for me.
public class SomeClass
public static void main(String args[]) throws Exception
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
DocFlavor flavor = DocFlavor.INPUTSTREAM.GIF;
PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
PrintService service = ServiceUI.printDialog(null, 200, 200,printService, defaultService, flavor, pras);
if (defaultService != null)
DocPrintJob job = defaultService.createPrintJob();
FileInputStream fis = new FileInputStream("somefile.GIF");
DocAttributeSet das = new HashDocAttributeSet();
Doc doc = new SimpleDoc(byteArrayOutputStream, flavor, das);
job.print(doc, pras);
Thread.sleep(10000);
If u do not want the dialog box to appear and just print to the default printer of the local machine use the following code
public class SomeClass
public static void main(String args[]) throws Exception
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
DocFlavor flavor = DocFlavor.INPUTSTREAM.GIF;
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
if (defaultService != null)
DocPrintJob job = defaultService.createPrintJob();
FileInputStream fis = new FileInputStream("somefile.GIF");
DocAttributeSet das = new HashDocAttributeSet();
Doc doc = new SimpleDoc(byteArrayOutputStream, flavor, das);
job.print(doc, pras);
Thread.sleep(10000);
Mean while if some body comes across any tweaks to print PDF documents using j2se1.4 please write to me at

Use of DBlookup API and find particular receiver

Hi all,
The scenario is :
soap req -> XI -> req to external database -> resoponse from db to XI -> BAPI request -> response from BAPI to XI -> send response to SOAP Response
I found that DBlookup API (User defined function to get data from External Database) is very useful to achieve this scenario without BPM
now question is :
There are multiple SAP HR Systems, how can i determine particular HR system based on URL data received from external database? Each SAP HR system uses same BAPI structure.
Also it will be great if anybody share any document or information regarding fetching data from external database.
Regards
Ritesh
Edited by: chintan patel on Apr 4, 2008 6:33 PM

I've to use BPM in this scenarion because eventhough I am getting data from external database I am not able to put condition on that fields. For example In this case I've to find out the particular SAP (receiver) system based on URL field, which is coming from the database. But in XPATH I am not able to fetch this URL. I can fetch only source structure fields. So BPM is the best soulution for this interface.
Thanks all for contributions. Appreciated

Developer portal documentation out of date and frustrating

FYI: this is just a rant to apple and a big thank you to this forum!
I have solved all my issues and finally have apps running on my testing device.. but no thanks to the out of date and confusing documentation. If it wasn't for this forum, I still will be figuring out how to select provisional profile in XCode.
Problems with the documentation:
1. "Installing iPhone OS":
I spent hours looking for "OS X iPhone 2.0 .ipsw" on the dev center. I thought to myself, do I really need this? I convinced myself, it must be a special version of iphoneOS for developing. I mean why else would it still be in "how to guide". Thanks to the forum for telling me otherwise. I still do not know if you have to "restore ipod". I ended up restore ipod just in case.
2. Generating an App ID:
What's with the asterick.. At least the document got that right and specifically tells you to enter an "*". But if you should always enter an asterick then why even make that a step to perform. Is there any reason to not enter an "*"??
3.Running your Development App on a provisioned device
Here's where I had the biggest trouble:
"In the Project Info window, select the ‘Build’ tab and enter “iPhone Developer: <YourFirstName> <YourLastName> in the ‘Code Signing Identity’ > ’Any iPhone OS’ field setting. This is the also the Common Name of your iPhone Development Certificate."
Ugh FIX THAT LINE in documentation. It drove me nuts.. you see I placed "IPhone Developer: Rick Mullinix" in for Code Signing Identity. Which seems correct, that is my identity. But no, that leads to not seeing provisioning profile as a choose.
Thanks to the forum, I changed the identity to "IPhone Developer".. and it works!
But that leads to another question... how does "IPhone Developer" identitfy anybody? We are all "IPhone Developer(s)".. I guess we are all thought to be the same by Apple.. might as well make everyone place "Cash Cow" as their identity.
4. Over all:
I am still confused by all the certificates, profiles, key chains.. seems all magical to me, it works and all, but I wish documentation had better wording and definitions to help my understanding.
-Thanks again to this forum, and I hope that "Distributing my App" wont be as difficult.

1. No, you don't have to restore your ipod. As long as you're running the fw 2.0 (and above) your ipod is ready for development.
2. don't know. i'm just glad that it works
3. Just look into your keychain under Certificates. There should be one named "iPhone Developer: <your> <name>". Enter that line in xcode. "iPhone Developer: Jon Doe" for example. You just have to enter the exact name of the certificate in xcode.
4. Yeah, that stuff is pretty confusing. My Dev-Account got activated yesterday and I spent the whole day just setting up my certs and tax-info. It was really frustrating and time consuming. I'm (negatively) surprised by the ammount of real paperwork you have to do. It just doesn't get in my head that you have to print and snailmail that many letters for something like an internet application store. But that's another story
just my 2 rest-of-the-world cents

Can we develop EP(enterprise portals) using sap work bench?

hi,
i know that we can develop portals using NWDS. But i want to know can we develop EP using sap work bench or any other transaction.

Hi Arafat,
I was trying to post few links from SAP Technical website. But, it is not allowing me post that links on here. You can have a look on their website as well. They have got some really good tutorials on EP and Webdynpro ABAP/JAVA.

JAVA API AND ABAP API SIMPLE SCENARIO

Hello MDM gurus
I have never used any Java API or ABAP API to leverage and present MDM functionalities on front end systems like portal,etc...
Could you please give me all the required to play around with JAVA api and ABAP api's.
Points will be given to every valuable answer.
Thanks

Hi Nazeer,
In order to use Portal you need Java APIs and to start with refer the MDM Java docs to get the basic idea of various classes and methods to be used in developing the simple java application and access it using portal.

When i try to run more than one servelt of the Quick Start samples that using Livecycle Java APIs and i get an error of "Remote EJBObject lookup failed for ejb/Invocation provider" from any servelt i run.

I assume here that your application is deployed on a different physical machine of where LCES is deployed and running.
Do the following test:
- Say that LCES is deployed on machine1 and your application is deployed on machine2. Ping machine1 from machine2 and note the ip address.
- Ping machine1 from machine1 and note the ip address.
The two pings should match.
- Ping machine2 from machine1 and note the ip address.
- Ping machine2 from machine2 and note the ip address.
The two pings should match.
Usually this kind of error would happen if your servers have internal and external ip addresses.

Start to develop portal

Hi all
I am new to 9iAS portal. I would like to know how to start to learn and develop portals using 9iAS, any books hints..
And also I would like to know what is PDK??...Using PDK can we develop portals without installing Oracle 9iAS..Where can I find details regarding these??.
Please any help is appreciated..
Thanks a lot

Hello,
The best start will be to take a look to PortalCenter Web site for overview of the features and benefits of OracleAS Portal.
For development perspective you can use PortalStudio, this is the place where you will find all the information -sample,technical note, how tos, ...- about the PDK.

Problem using Java Mail API with WLS 7.0

Can anyone please tell me what is the problem. I thought that we cannot directly
do
InitialContext ic = new InitialContext();
So I had written a method getInitialContext() as shown in the above piece of code,
but that too did not work.
Eagerly awaiting a response.

You can use InitialContext ic = new InitialContext() only if you are using a startup class, servlet or a JSP i.e
server side code.
If you are using a java client you need to use Context ic = getInitialContext();
Try this code
import java.util.*;
import javax.activation.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.naming.*;
import java.io.*;
import java.net.InetAddress;
import java.util.Properties;
import java.util.Date;
public class MailTo {
public static void main(String args[])
try {
Properties h = new Properties();
h.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
h.put(Context.PROVIDER_URL, "t3://localhost:7001");
Context ic = new InitialContext(h);
Session session = (Session) ic.lookup("testSession");
Properties props = new Properties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", "XX.XX.XX.XX");
props.put("mail.from", "[email protected]");
Session session2 = session.getInstance(props);
Message msg = new MimeMessage(session2);
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse("[email protected]",false));
msg.setSubject("Test Message");
msg.setSentDate(new Date());
MimeBodyPart mbp = new MimeBodyPart();
mbp.setText("This is a mail sent to you using JAVA Mail API and Weblogic Server");
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp);
msg.setContent(mp);
Transport.send(msg);
catch(Exception e)
e.printStackTrace();
}//end of main
}//end of class
We have shipped a javamail example in the samples\server\src\examples\javamail folder.

Can anyone please tell me what is the problem. I thought that we cannot directly
do
InitialContext ic = new InitialContext();
So I had written a method getInitialContext() as shown in the above piece of code,
but that too did not work.
Eagerly awaiting a response.

Use both CAN APIs

Hi,
I am developing an application that talks to a microcontroller. I would like to use the Frame API for setup where I can send commands and get responses, and would like to use the Channel API for a mode where I am simply monitoring messages that I receive from the micro.
I have a state machine where I begin by opening the Frame API, have some different states that i go into which utilize the query/response aspect of the frame API and then a state which closes the Frame API and opens the Channel API. The problem that I am having occurs when I have already closed the Frame API and started a read task with the channel API. When I click the stop monitoring button, I exit the While loop which was reading a message defined in the Can DB (havn't actually had it read data yet) and execute the Channel APIs CAN Clear.VI i get the following error.
Error - 1074388720 occured at CAN Initialize.vi
Possible reasons:
NI-CAN (Hex 0xBFF62110) You cannot use the Frame API and Channel API simultaneously on the same interface (such as CAN0). tools in MAX use the Channel API. Soultuon: Use a different interface with each API.
I need a way to work around this and am not sure why the Frame API isn't seeming to be closed, especially since I have a state in my state machine to close the Frame API before I begin using the Channel API.
If anyone has any suggestions please let me know.
Thanks,
Gary
Solved!
Go to Solution.

sorry i will attach it all again so it can be run. Use this VI. it has a tab control. when the program starts, the frame api is running and then you click stop and switch the tab to see the channel api running. when you click the stop button on the channel api you should see the error.
the error has been occurring every time, but when i just ran it, it didnt give that error. I still think the problem exists and I see the problem in my real app that basically does the same thing.

Problems while uploading files using the FileReference API

I've built an image uploader module in Flex using the FileReference API and PHP.
While this works perfect for images upto 1 MB, What I'm noticing is that for images greater that 1 MB even after the Event.COMPLETE has triggered, the file hasn't yet been uploaded into the folder.. its only after a couple of seconds or minutes after the Event.COMPLETE, that the image actually shows up in the FTP folder. Morever I also noticed that for such files the DataEvent.UPLOAD_COMPLETE_DATA that we are using to get feedback from PHP never gets called.
I thought it would be related to the PHP script getting timed out... but the PHP script does get executed and the images do show up in the folder but thats way after the Event.Complete has been triggered and more importantly DataEvent.UPLOAD_COMPLETE_DATA doesnt get called.
Everything seems to work fine as long as the file size is under 1 MB
Did others too face similar problems and any ideas on how to fix it?
Thanks in advance

I don't believe there is, as the browse button renders out as an html input type file component, and this has no ability to get native file size from the client. The only way to do it is to check the file size server side, but that kind of defeats the purpose to some extent, as the file is required to be uploaded before the file size can be checked.
There is no way to do this on the client short of using a third party client side component - ie. java, flash or some other active component that gets file system level access.

Encrypt/Decrypt data, multiple public keys using Bouncy castle api?

Hi all.
I need to implement encrypt/decrypt functionality of some data with many public keys using bouncy castle api and EnvelopedData class in java 1.4 SE.
Could someone give me examples how to do it. I searched whole the internet and i could not find simple example.

Hi thanks very much.
I had a quick look at the examples. I will see if they could help me.
Here is more specific what i want:
Encrypt data with multiple public keys that are kept in .pkcs12 file.
And decrypt the data using coresponding private key after that.
I must use bouncy castle api for java 1.4 se.
Best regards
