My JSP Report doesn't work !!! Help me !!!

What's up friends! I holp that so good!
My question is very simple, I've been building a JSP Report with JDev and Report Builder, but when I has tryed to run the report from inside JDev, the IE has started with the LOADING... page and nothing happened.
I have Oracle9iDS and Oracle91AS installed on the same machine, I started the HTTP Server and Oracle9i Report Service before run the report.
I've been reading a lot of documents but I don't know what I need to do.
What is missing to configure to work well?
Please, help me!!!

You need to create a JSP report from JDev's new object gallery from 'File -> new... -> Reports Objects', so that the project settings can be prepared to run JSP report.
If you want to run JSP report on a standalone Reports server, put 'server=<server_name>' in 'parameters' attribute of <rw:report> JSP tag.
You can also use rwservlet's in-process Reports server, by not specifying 'server=...' in 'parameters' attribute. No standalone Reports server is needed. Make sure JVM is set to'hotspot' in JDev's project settings -> runner.
When running JSP in JDev, it uses JDev's embedded oc4j web server.

All of a sudden, report doesn´t work anymore

Getting really tired of this whole SCOM-thing the last days.
Now the reporting doesn´t work anymore. We changed NOTHING.
State went from Zero to Healthy 4:14 PM on friday last week. Alright.
But a few hours later, when nobody was here anymore, it changed to EROR.
How can that happen?
Reports are EMPTY suddenly. You can't start report-tasks anymore. They disappeared.
We checked:
- Discovered Inventory -> Data Warehouse Synchronization Server
- State is Critical.
- Display name is wild numbers+characters, is this normal?
- Health explorer says:
'DeploymentException': Failed to deploy reports for management pack with version

Hi,
Generally these errors are caused by improper SQL SRS configuration, to confirm SRS is initialized correctly, are you able to navigate to http://localhost/reports or http://localhost/reportserver?
Are you upgraded to SP1 RC yet and have you the latest versions of the MP' as a lot of these reporting issues have been resolved?
Also re-check all your SRS accounts have the relevant permissions and all permissions in IIS are correct?
You could try resetting the SRS configuration and re-install Reporting.
1. COPY the ResetSRS.exe file in SupportTools folder of the OM 2007 media to
C:.
2. Open a Command Prompt and change your path to C:.
3. Type "ResetSRS.exe MSSQLSERVER" where MSSQLSERVER is your SQL instance
name.
4. Then open Reporting Services Configuration Console, select Web Service
Identity and click Apply.
5. Finally, reinstall your reporting service by running OMSetup.exe again.
In addition, please provice the event ID under event vierwers, so that we could analyze it further.

HT1222 Hey, I've tried to install the new iOS 7.1 but it says that the installation cannot be completed and doesn't say why. I have more than 50% battery left but it still doesn't work, help?

Hey, I've tried to install the new iOS 7.1 but it says that the installation cannot be completed and doesn't say why. I have more than 50% battery left but it still doesn't work, help?

It probably means you don't have enough available storage on your phone. It takes space to store the download - THEN unpack it. Best method is to use a computer with iTunes (This allows you to back up on your computer as well).
PLEASE: Do not purchase iCloud storage space - this will not give you more room for the iOS 7.1 installation.

Link to detail Report doesn't work.

Hi, we are using Webi for On Demand reports (against Salesforce universe) and the hyperlinks to details reports are not working.
my URL in master report looks like this:
="<a href=https://na.crystalreports.com/opendoc/openDocument.do?iDocID=48877773&sType=wid&sWindow=New&lsMFocusBook="[Focus Book]"&lsMSegment="[Segment]"&lsMAccount="[Account Name]">"[Segment]"</a>"
and UR in detail report appears as:

Some how details report doesn't recognise the propmpt values and always asks to fill prompts.
can some one advise?
Thanks

Hello,
The openDocument.do url was really only designed for use with Crystal Reports documents.
It is not officially supported for webi documents, or any of the other document types.
That being said, it sounds like opening webi docs with openDocument.do does work, it is just the parameter passing that is problematic.
Cheers

Web fault reporting doesn't work

My phone line was tested and it came back as working but it isn't. I have removed all extensions and tested with 2 different phones at the master socket and a fault still occurs. The line works after a fashion but doesn't ring properly and also sometimes loses the incoming phone number information. Broadband is ok.
But the BT web site won't allow me to report it because the line was tested as ok but I know it isn't. This is a failure of customer service.
Also this link doesn't work (I am using Mozilla Firefox not Internet Explorer but this shouldn't make a difference)
https://www.bt.com/consumerFaultTracking/public/faults/reporting.do?pageId=21&s_cid=con_FURL_faults
So I can't use the web site to report the fault and I had to call an 0800 number with a mobile.
Not good.

The website is working fine from your link posted also you can call BT from this number From a mobile: 0330 123 4151 the charge for this call will come from you mobile calling plan

Scale of the graphic in interactive report doesn't work in french

Dear all,
I created a calculation column in an interactive report an put the format 9999999D99. When I displayed the information everything is ok.
After that I tried to create a graphic with this column.
The graphic is the type line
The value is this new column
The function is SUM
order by label ascending
The graphic show the good information, when I click on the dot the right number is displayed (19459,10). But if I look on the scale on the left the numbers are not good, we see 25,00000 instead of 25000,00.
The application use the navigator information the first language use is french. If I use english the numbers are ok.
What I need to do to use french and have the right decimal ?
Thanks for your help

Hi Pranay and Mohd,
here is the screenshot:
If I logon as Admin user (or I grant user Admin rights), it looks like this:
So the prompt is visible but is empty. I changed privileges in CMC / Applications / Web Intelligence, so normal user has same right as Admin, but it still doesn't work. I also tried change user security in Connections and Universes, but none of them work.
Please, do you have any idea what i miss?
Thank you

HELP! Uploading AS3 Game to server, no sound and Spacebar doesn´t work HELP!

Hello, relatively new to AS3 and flash, this is the first time i am publishing anything. We are trying to upload our simple flashgame to our webserver, the game works perfectly fine locally save for one thing. We get an error regarding TLF which says it wont stream or something. So when it gets online, no sounds play and spacebar doesn't work, left and right arrow does work. We have three TLF text fields that are used to update score, lives and show you final score. If i turn these into classical text they stop working.
Things we have tried: Changing default linkage from RLS to Merged into code, changing the text boxes to classical text(they then stop working), made sure the paths are correct(all files are in the same directory including the .swz file)
This is the code from the soundclass:
package
    import flash.net.URLRequest;
    import flash.media.Sound;
    import flash.media.SoundChannel;
    import flash.events.*;
    public class MySound
        private var bgSound:Sound;
        private var fireSound:Sound;
        private var waterSound:Sound;
        private var earthSound:Sound;
        private var lightSound:Sound;
        private var soundChannel:SoundChannel;
        public function MySound()
            soundChannel = new SoundChannel();
            bgSound = new Sound();
            var req:URLRequest = new URLRequest("BackgroundSound.mp3");
            bgSound.load(req);
            //fire
            fireSound = new Sound();
            var req2:URLRequest = new URLRequest("soundFire.mp3");
            fireSound.load(req2);
            // water
            waterSound = new Sound();
            var req3:URLRequest = new URLRequest("soundWater.mp3");
            waterSound.load(req3);
            // earth
            earthSound = new Sound();
            var req4:URLRequest = new URLRequest("soundEarth.mp3");
            earthSound.load(req4);
            // light
            lightSound = new Sound();
            var req5:URLRequest = new URLRequest("soundLight.mp3");
            lightSound.load(req5);
        public function playBgSound()
            soundChannel = bgSound.play(0, 999999);
        public function stopBgSound()
            soundChannel.stop();
        public function playFireSound()
            fireSound.play();
        public function playWaterSound()
            waterSound.play();
        public function playEarthSound()
            earthSound.play();
        public function playLightSound()
            lightSound.play();
I can somewhat get that sound can bugg out, but why does spacebar stop functioning? ANy help is greatly appreciated as this has to be delivered in twelve hours(published online) for a school assignment.

Also might add publishing it locally in my own browser everything works, as does ofcourse playing it in flash itself. Changing from RLS to merged into code stops the error from coming, but doesn´t fix the problem on the server.
Code from main class related to sound and spacebar:

Interactive Reports - group by in SQL - download reports doesn't work

Hi,
I have the following SQL as the region source of an interactive report.
select SERVICELEVEL, SUM(CONTRACTVALUE), SUM(DOLLARVALUE), count(SERVICELEVEL) from "ACSPROD"."CONTRACT" where CONTRACTSTATUS='Active' group by SERVICELEVEL
The report shows exactly as expected. I have also integrated BI Publisher 10.1.3.4.1 with APEX 3.2.0.00.27
Problem 1
The report download doesn't work for any of the formats (CVS/XLS/PDF/RTF). When I rewrite the SQL without the group by clause (not the wanted results), then the report downloads work.
What am I doing wrong?
Problem 2
Irrespective of the above issue - when I add a sum aggregate and download the report (any format) - it doesn't show the summed value.
What am I doing wrong?
Please advise!
Cheers
Mynhardt

Hi Pratadamski ,
I could reproduce this issue at my end. This is a bug. So, I have filed on your behalf (6432429).
When i use tables ( not views) directly in my SQL and use column alias for computed column, it does work fine!
i.e., this query is good with databinding at designtime and runtime:
SELECT ALL trip.PersonID,
COUNT(*) AS Num_Trips
FROM trip
GROUP BY trip.PersonIDThanks & Appreciate your feedback,
Sakthi

Stuck on apple logo and Home button doesn't work, help please?

Well, I dropped my iPod Touch 4g by accident and since that day, the home button hasn't really been working that well. Its very hard to use since you have to press it in really hard to get it to work and sometimes it doesn't even work at all. Anways, I was skyping with my girl and I didn't notice that I had to charge the iPod and it died on me so I was like what ever its normal and started to charge it. When it turned on, it got stuck on the Apple logo and its been there for more than a day now? What can I do? I know about the Press Home + Sleep button together but the Home button doesn't work at all anymore. I tried everything really. I tried to connect it to itunes and see if I could restore it but it won't recognize it no matter where I connect it. Tried it on 3 different computers and none worked at all. I can't take it to an Apple store since there isn't any close to where I live and I really don't have anyone to take me there. So is there any other solution to fix my problem at home? or is it messed up completely? Someone please help me

I have this same issue. But also, it isn't just that the lock/home button stops working, all buttons stop working. Even if you switch it to silent sounds are still played. I just got my iphone Thursday. Went to school the next day and pulled it out, it happened while it was locked I guess because my screen was black and I couldn't do anything! Thought it died already! This was around 12. Finally I pulled it out of my pocket again at around 3 and it showed the Apple logo and acted like it had just started back up. Which is what always happens after I get stuck playing a game or something. Help please, has happened two or three times just today.

Upload file jsp code doesn't work? How can I debug

Hi Everyone,
I have the following jsp code that simply adds a new product to the backend database when 'Continue' button is pressed.
if( "Continue".equals(fp.getParameter("Submit")) ) {
     fp.setParameters(prodForm);
     prodForm.setCreateBy(currentUser.getUserID());
     prodForm.save();
     String filename = fp.getFilename("file");
          if( filename != null ) {
          // a file was uploaded
          // set the path to save it
          fp.setFilePath(PHYSICAL_PATH + "uploads\\");
          // we will change the filename to make sure it is unique
          // need to keep the file type
          String fileType = "";
          try { fileType = filename.substring( filename.lastIndexOf(".") ).toLowerCase(); }
          catch( Exception e ) { fileType = ""; }
          fp.saveFile("file", "POS_" + prodForm.getProductID() + fileType);
          prodForm.setSketch("POS_" + prodForm.getProductID() + fileType);
          prodForm.save();
     db.close();
     response.sendRedirect("index.jsp");
     return;
}The code works fine but the upload doesn't work. This is the upload part of the above code:
String filename = fp.getFilename("file");
          if( filename != null ) {
          // a file was uploaded
          // set the path to save it
          fp.setFilePath(PHYSICAL_PATH + "uploads\\");
          // we will change the filename to make sure it is unique
          // need to keep the file type
          String fileType = "";
          try { fileType = filename.substring( filename.lastIndexOf(".") ).toLowerCase(); }
          catch( Exception e ) { fileType = ""; }
          fp.saveFile("file", "POS_" + prodForm.getProductID() + fileType);
          prodForm.setSketch("POS_" + prodForm.getProductID() + fileType);
          prodForm.save();
     db.close();
     response.sendRedirect("index.jsp");So if the file browser, <input type="file" name="file">, has a file, then it saves the file in the upload folder and saves the filename in the database. But it doesn't work, it doesn't save the file in the upload folder nor it saves the filename in the database. I am new to java and jsp so could you tell me what error checking or deguging I can do in jsp to spot the problem.
Thanks,
Zub

where u write the code to upload the file
to server end?

It looks like a bug in JSP generator. If you look and the .java
          created by 6.1 it doesn't make any sence:
          String _propertyValue = request.getParameter("short");
          if (_propertyValue != null && !_propertyValue.equals(""))
          test.setShort(null);
          (needless to say that this works correctly in Resin).

Atan in jdk1.1.8 doesn't work. help

I am creating a program which simulate the effect of gravity on a object (for a game). For this I am working with jdk1.1.8. (not by choice). But for some reason the movement of the object just turns around. I believed that de method Math.atan2 was wrong so i have rewritten it and it worked better. But the method atan most likely doesn't work either because it is not perfect yet. Does anyone know or have an implementation of de atan method in java that works so i can use it? Because I don't know how the method works.
maybe i am wrong here but it is basicly the only solution to my problem. if give the code of the bullet class with it. maybe anyone sees the problem there:

I have allready tested my code to the max en I have redone the calculations about 4 times, because I couldn't believe the fault was in the method atan or atan2 from sun. But since my calculations should work in theorie (worked it out with a math teacher) it's the only options I could think of.
[qoute]
I haven't looked up in the API docs how atan2 is supposed to work, but I noticed these two lines in your code:
forceAngle = atan2(dy2,dx2);//the angle of the force with the y-axis
travelAngle = atan2( (x-oldx), (y-oldy) );
In one place you use Y and X as the parameters and in the other case you use X and Y. They can't both be right.
[qoute]
In this case it is. because the forceangle is opposite the x-axis and thus the two must be reversed. (travelangle is opposite the y-axis).
I have also tried to reverse them (for both) but the effect got worse :)
Thanks anyway.

Jsp:include doesn't work with Tomcat & IIS

Hi, Guys,
I installed IIS4.0 and Tomcat in my windows NT system. http://localhost/examples/jsp/index.html works fine.
When I load http://localhost:8080/about.jsp, it's also working fine. But when I load http://localhost/about.jsp, it will ignore the part which the line is display as
<%String topName = "/servlet/topServlet";%>
<jsp:include page="<%=topName%>" flush="true"/>
The other part will work just as a html file. And I didn't get any error message.
Would can tell me how to figure out this problem. Thank in advanced very much!

Oh, God, why not tell me earlier!!!!!! I do use tomcat 3.1 and it just support servlet. I have no way out but modify all my jsp:include to encoding into a servlet page. I almost re-do all my work. But anyway, thank you! Next time I will know.
