I need to achieve performance in using URL

Which api better supports in increasing performance regarding URL
* org.apache.tomcat.util.net.URL or java.net.URL*

It's the requirement by our client. As of now we are using java.net.URL and running application with sequence of requests and responses. The requests are as high as more than 6000. So performance issue is came into picture. Our client needs to use apachi api. We dont know whether it'll increase performance or not, just to know whether apachi api helps us in this matter???

Performance slow using url BufferedReader

I'm reading the contents of a url using BufferedReader, it takes a while to read the url into my application, what could be done to speed it up. Here's the code.
DiscovererUrl = https://url_to_site
URL myurl = new URL(DiscovererUrl);
HttpURLConnection con = (HttpURLConnection)myurl.openConnection();
InputStream ins = con.getInputStream();
InputStreamReader isr=new InputStreamReader(ins);
BufferedReader in =new BufferedReader(isr);
StringBuffer inputLine=null;
StringBuffer entirehtml=new StringBuffer();
String entirehtmlafter = "";
StringBuffer str = null;
StringBuffer str2 = null;
try{
while ((inputLine = new StringBuffer(in.readLine())) != null)
entirehtml.append(inputLine);
catch (NullPointerException npe){}
in.close();
isr.close();
ins.close();
con.disconnect();

it takes a while to read the url into my applicationWhat is 'a while'? Maybe it's because the site is not responding fast anyway.
Don't forget that with SSL it's slower.
By the way, you don't need to instantiate a StringBuffer for each line read:
while ((inputLine = in.readLine()) != null)
entirehtml.append(inputLine);

Getting error in using URL View in Task Flow

Hi,
Using Jdeveloper: 11.1.1.3.0
What I am trying to achieve is that an ADF application can be bookmarked, and when it is open without a valid EBS login context, it should redirect it to the EBS login screen. In method initMainPage , I have code that determines if valid session exist or not. If not, then redirect to a login screen (which I trying to implement using URL View component).
I am using a Bounded Task Flow. and the flow within is as follows:
methodCall1 -> initMainPage (AM method) -> URL View
For URL View, URL property is set to: #{MainPageContainerBean.ebsLogoutURL} . ebsLogoutURL is a String in MainPageContainerBean, with getter and setter as below.
public String getebsLogoutURL() {
return ebsLogoutURL;
// return "/oracle/apps/flm/ekanban/common/ui/page/ParameterEntry.jsff";
public void setebsLogoutURL(String ebsLogoutURL) {
this.ebsLogoutURL = ebsLogoutURL;
This task flow is part of a JSPX page. When I run the JSPX page, it give me the following error.
<Feb 2, 2011 1:30:37 PM PST> <Error> <HTTP> <BEA-101020> <[ServletContext@4396218[app:ekanban module:ekanban-UI-context-root path:/ekanban-UI-context-root spec-version:2.5]] Servlet failed with Exception
java.lang.IllegalStateException: Attempt to validate an already invalid RegionSite:
at oracle.adf.view.rich.component.fragment.UIXRegion$RegionSiteImpl.validate(UIXRegion.java:978)
Please suggest a resolution or workaround to the issue.
Thanks,
Anoop

Now it is working. I didnt know that I needed to create getter and setter for the string that i refer to in the EL. Thanks for your help.

Performance degrades using more then one Textfield

Hi everyone,
I noticed that performace in my app degrades noticeably when there is more than a Textfield on stage. I need to have two dynamic text field displayed at the same time, which is the best way to achieve this without using too much processing power?
Thanks.

I'm testing on the first Iphone model. Basically when the user put some information in two input field the input field disappear, the background change and some dynamic text is displayed. This happen with a fade out effect done playing with the alpha of a white bitmap. I know I shouldn't use alpha property but performance are still fine if a insert only a text field it start to slowdown only with two so I was hoping some tuning on text fields could help me to avoid this.
I just discovered that if a cache text field as Bitmaps i fix the speed issues but text changes color in a light blue, I really don't know why

How do I access "Firefox is NOT compatible with this application. For best performance, please use Internet Explorer 5.0 and above...." web sites; when I try to download any alternate browser, then a warning that alternate is "imcompatable with your opera

How do I access websites that warn: "Firefox is NOT compatible with this application. For best performance, please use Internet Explorer 5.0 and above...."? When I try to download any alternate browser, all I get is another warning that the alternate is "not compatible with your operating system." Is Firefox preventing this? The site listed below is a job application site. I've had this same problem with other job application sites also.
== URL of affected sites ==
https://storefront.kenexa.com/lithia/cc/Home.ss

There should be a User Agent Switcher menu item under Tools, which gives you the browser names you can impersonate.
The menu item name changes to the browser UA you are presently using.
There is also a User Agent Switcher button, you can add it using View -> Toolbars -> Customize, and dragging the button to your toolbar.
See http://chrispederick.com/work/user-agent-switcher/features/ and http://chrispederick.com/work/user-agent-switcher/help/
You can just start trying IE versions (or the versions it says on the site) until it lets you in.

Open BI Publisher report using URL View activity

Hi,
i need to call BI Publisher report and I want to use URL View activity (i followed instruction on http://oraclebizint.wordpress.com/2007/07/30/customizing-obi-ee-%e2%80%93-go-url-parameters/ but i can't have HTML Form inside af:form)
But parameters on URL View activity are visible and i have to send username and pass..
Is there another way?
Tnx.
Andreja

Yes, I can put HTML form at top or bottom of page but i wanted to put in panelCollection (because of page design)....
but I will think out something to look nicely too :)
Tnx

The Web application at could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application

Hi,
I have created on windows service to fetch sharepoint list ad update the list items.
when i run this service in sharepoint server(where the sharepoint site is hosted),it is working fine. If i run the same service in another machine(sharepoint installed in this machine also). it is giving the below error
The Web application at [URL] could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.

I have pointed .net framework to 3.5 version and target palform as Any CPU. Please suggest me

Hi mallela1,
I also had similar issue couple of months back when I was trying to access a remote URL from a Windows service when the site does not exists in the server where service resides.
You cannot access a remote url (even though it is SharePoint server and also in same network ) from server object model.
SPSite can look in the current server only. here what is happening is SPSite will look for this in the current server DB and it is not finding this errror.
So please dont use ServerObject model for accessing remote sites. You can use Client Object model for the code /requirement you have stated above.
I wasted lot of time in finding a work around to make to work. It did not. So look for other options.

Design Choices and is LiveCycle needed? best practices for using RTMP/AMF over HTTP/XML communicatio

Hi,
I am new to flex/RIA. I am exploring different design choices especially in client server communication. On client side we will be using Flash based RIA (using Actions scripts).
There will be some simple forms (like for login, registration, payments etc) and some simple reports including with several graphs and charts. Each chart might have 1000 to 1500 data points etc. There are not video or audio content as such. On server side we have Servlets, java API and some EJBs to provide the business logic and real time prices/content (price update is usually every 10 seconds) /data. Some of the content will be static as well.
I have following questions in my mind. Is it worth it to use RTMP/AMF channels for the followings?
1. For simple forms processing (Mapping Actions scripts classes to Java classes). Like to display/retrieve/update data for/from registration forms.
a. If yes, why? Am I going to be stuck with LCDS? Is it worth it? What could be the cons for heavy usage/traffic scenarios
b. If not what are the alternates? Should I create the web services? Or only servlets are sufficient (ie. Only HTTP+Java based server side with no LCDS+RTMP+AMF)? All forms need to communicate on secure channel.
2. For pushing the real time prices/content which we may need to update every 15 seconds on user interface using graphs and charts. Can I do it with some standard J2EE/JMS way with RIA (Flex) on front-end? i.e. Flash application will keep pulling data from some topic. Data can be updated after few secs or few minutes which cant be predicted.
3. Are there any scalability issues for using RTMP? What happens if concurrent users increase 10 times within a year?
4. What are the real advantages of using RTMP/AMF instead of simple HTTP/HTTPS probably using xml based objects
5. Do I need to use LCDS if I am using AMF only on client side? Basically I mean if I am sending an object in form of xml from a servlet. Can some technology in Flash (probably AMF) in client side map it an Action script object?
6. What are the primary advantages of using LCDS in a system? Is there any alternate solutions? Can I use some standard solutions for data push technologies?
I would like that my server side implementation can be used by multiple types of clients e.g. RIA browser based, mobile based, third party software (any technology) etc.
I appreciate if you can kindly refer me to some reading materials which can help me deciding the above. If this is not the right place to post this message then please do refer me to the place where I can post such questions.
Thanks and Kind regards,
Jalal

Hi Jalal,
Let me see if I can help with some of your questions
1. Yes, you can use LCDS for simple forms processing. Any time you want to
move data between the Flex client and the server, LCDS (or its free Open
source cousin BlazeDS) is going to help. I would expect you would use the
mx:RemoteObject MXML tag to invoke server side code, passing it the form
data input by the application user.
2. If you need to push near real-time data, LCDS gives you the RTMP channel
which can scale quite nicely. You can then use the mx:Consumer MXML tag to
subscribe the clients to the messages, which can come from almost anywhere,
include JMS topics or queues.
3. RTMP (included in LCDS) is the best option for scaling to tens of
thousands of users and the LCDS servers can be clustered to proved better
scaling.
4. The AMF3 protocol used over the RTMP channels performs much faster than
simple XML over HTTP. See this blog posting for some tests:
http://www.jamesward.org/census/.
5. If you are sending a Flex application XML, then I would recommend using
the E4X API to work with the XML. This is a pretty nice and powerful way to
work with XML. If you want Actionscript objects (and probably better
performance), then using AMF serialization to Actionscript objects is the
way to go.
6. Primary advantages? There are many, but mainly you can avoid thinking
about the plumbing and concentrate on solving your application and business
logic problems.
Hope this helps you a little

What are the steps needs to be perform to define a data model

What are the steps needs to be perform to define a data model
a. Information Gathering
b. Hardware & Software
c. Structure the Information MDM
d. Transfer into a Physical Model BW data model
e. Explore use of existing model Business Content

Hi Siva,
 Very first activity is Proof of concept (POC), here we have to show How BW works for clients Reporting requirement during POC we as BW consultants need to creat some sample BW back end objects and also some reports based on business requirement. This is very crucial stage as Client Judge wethere BW would meet his demands. If every thing is fine then next step is Bidding.
After Bidding the contract then actual Project intiates. from here we follow ASAP methodology.

Project Preparation
Here Senior Consultant would go to Client place for Business Process Transistion and to know in what way the Architectue should be set up so here Basis People will come into picture.
Blue Print
Transistion could be understood by BRD (Business Requirement Documents) BRD states what is exact requirement and it is given by End users.
 By seeeing thr BRD's we as BW consultants must prepare APPlication Design Documents . The Application Design Documents states all the Technical aspects that needs to be performed as BW backend and also as well as Frontend.
Realization Phase
Here as BW consultants we must start confuguring as mentioned in ADD's by taking care of all performance aspects, once all the configuration are done we do Unit testing. unit testing is an activity where we check all the design process wether it running correct or not. After unit testing we move the design objects to Qulaity for Integration Testing.
Testing
 Here end user will check all the objects, reports on end to end basis. after integration testing is done then UAT ( User acceptance Testing) would come into picture where user check each process and sign off.
Go live
Here all the object will be moved to Production where end users and power users can start working on the system. intially for some days Development team would be taking care of all support activites there after it will be transitoned to support team.
Hope It helps you.
Assign Points if it usefull

Using URL Parameters in a PDF Form

I built a form in LiveCycle Designer ES and I would like a couple of fields auto populated. The only way I could see doing this without having to purchase the LiveCycle Forms Server or another solution, is to embed the information in the URL.
I found a blog post about it on Stefan Cameron's blog: http://forms.stefcameron.com/2006/10/20/using-url-requests-in-pdf-forms/
I was able to get this to work, but when I try to allow the user to save their form locally, the form information get cleared when they try to reopen it.
I searched the NET and really couldn't find anything related to my problem.
Does anyone have an idea about this or should I be looking at a different solution?
Thanks,
James

I think that I was able to resolve this issue myself. After opening the PDF with URL parameters, you need to manually enter data into a field before saving. After manually entering data in a field and saving, the form contains all of the data.

Help with Video Performance Issues using Flash

Asking on behalf of a customer who has been unable to get any answers so far - are you able to help?
Background:
We have a port of our Game Development Kit which allows us to recompile all our games using Crossbridge (http://adobe-flash.github.io/crossbridge/) into SWF without any code modifications.
Overview:
Our framework is using OpenGL for rendering and we have successfully ported it along with the audio and video to run in Flash.
We are experiencing performance issues using Video. We cannot use image sequence as some of the video animations are too long and would increase the download to an unacceptable size. Assets vary between 256x256 - 1024x1024 videos.

Here's the rest of the story. Let me know if you can see any resolution, and I will connect him to the forums. Thank you.
Current Video Solution:
We create an instance of NetConnection, NetStream, and Video according to most samples out there, and invoke draw to rasterize the Video DisplayObject into a BitmapData instance.
The BitmapData instance has a fixed color component layout which is not compatible with Stage3D texture and is therefore has to be reformatted before uploaded to Stage3D Texture (See Code Listing below).
Our Problems:
Performance issues with RGBA conversion (either using copyChannel or manually reformatting is not fast enough) natively in as3; this required for stage3d texture.Copying each channel individual using bitmapdata.Copychannel seems faster, but not significantly faster.
Cannot detect when video frame has been updated, therefore we may copy pixels that are not needed in enterframe (processpixel).
Looping video, our current solution uses the NET_STATUS event Buffer empty; Is there a better way to loop videos than checking buffer and seeking to 0.
Stepping video, loading FLV or MP4 side by side assets from HTTP or embedded does not support stepping? Is there another way?
ActionScript Code Listing:
video_nc = new NetConnection();
video_nc.addEventListener(NetStatusEvent.NET_STATUS , onConnect);
video_nc.addEventListener(AsyncErrorEvent.ASYNC_ERROR , trace);
video_nc.connect(null);
// OnConnect Event:
this.ns = new NetStream(e.target as NetConnection);
eventclient = new Object();
eventclient.onMetaData = onMetaData;
this.ns.client = eventclient;
ns.play(flvfile);
ns.pause();
//onMetaData event:
this.width = infoObject.width;
this.height = infoObject.height;
this.textureWidth = NextPowerOfTwo(this.width);
this.textureHeight = NextPowerOfTwo(this.height);
cliprect = new Rectangle(0, 0, this.width ,this.height);
cliprect.x = 0;
cliprect.y = 0;
cliprect.width = this.textureWidth;
cliprect.height = this.textureHeight;
totalFrames = infoObject.duration * infoObject.fps;
this.hasAlpha = true;
if(infoObject.videocodecid == 5)
this.hasAlpha = true;
this.bitmapData = new BitmapData(this.textureWidth, this.textureHeight, hasAlpha, 0xff000000);
this.video = new Video(this.width, this.height);
this.video.attachNetStream(ns);
this.video.addEventListener(Event.ENTER_FRAME, processPixels);
// processPixel method:
BitmapData.draw(video);
GLAPI.instance.glBindTexture(GLAPI.GL_TEXTURE_2D,this.textureId);
var fmt:uint = GLAPI.GL_ARGB;
// converting pixels using copychannel or loop through pixels
GLAPI.instance.glBindTexture(GLAPI.GL_TEXTURE_2D,this.textureId);
GLAPI.instance.glTexImage2D(GLAPI.GL_TEXTURE_2D, 0, fmt, this.textureWidth, this.textureHeight, 0,fmt, GLAPI.GL_UNSIGNED_BYTE, 0, convBitmapData.getPixels(cliprect));

How to display the image which in KM folder using url iview

Hi Friends
How to display the image, which is under KM folder structur using the url iview.
i trying using url iview url as \document\testfolder\abc.jpg as url for the iview.
but its now working .. so please help me how to slove this problem
If is not the correct way then please suggest me best way to achive this.
Thanks
Mukesh

Hi Mukesh,
I think this may work,
1, Create a HTML Layout.
    You can put your image wherever u want with HTML Codes.
    Check this, [Article|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/3915a890-0201-0010-4981-ad7b18146f81] & [Help|http://help.sap.com/saphelp_nw04/helpdata/en/cc/00c93e9b2c3d67e10000000a114084/frameset.htm]
    With this, u can use the standard KM commands also.
2, U need to use KM Navigation iView for this rather than KM Doc iView.
3, In the Nav iView, u can use &rndLayoutSet=nameOfUrHTMLLayout to force the view with this new layout.
Regards
BP

Using url with username and password in URL class

Hi,
I'm writting an applet in which I use getAppletContext().showDocument with an URL.
The problem is that I'm using URLs with username and password (http://user:[email protected]/page) and it isn't working because the browser is getting the URL http://user/page.
Is this a bug in the URL class? Or in the showDocument method?
Is there any way to make this work?
Thanks for any help,
Pedro Prospero Luis ([email protected])

I'm not sure whether this is supported behaviour. I've had this syntax fail to work in the Netscape address bar so I can't recommend it as an approach for authentication.
If you want to authenticate the user before redirecting to the page, though, you could try creating a connection to another page on the same server and sending the authorization information then. Your browser may then be successfully authenticated.
See http://www.javaworld.com/javatips/jw-javatip47.html for information on this.
You might not need to read back the page from the server, just connect to it. Might work.
