Why is this throwing ClassCastException
case Types.LONGVARBINARY:{
int colIndex = rs.findColumn( columnName );
byte[] longvarbinary = rs.getBytes( colIndex );
break;
}I have the above code in my project.
Passing it a set of column names, some go through and for some, it throws the exception below even though the columns are of the same type
ensured by the surrounding case statement
java.lang.ClassCastException: java.lang.StringWhy would the resultset try and cast to a string if you have definetely said it will be a byte array??

this code is operating after an xmltype fails to validate. would this be the cause?
are there any simpler methods using pl/sql, the xmltype and xpath to modify contents of an xmltype instance?
any advice most appreciated.I can't answer the better/simpler method part of the question, other than to say there is an UpdateXML function but it works only from within the scope of a SQL statement. Not sure whether you'd want to make a SQL call just to do something to your XMLType that exists only in PL/SQL.
In regard to your current error, I can only say the following script does not produce an error. If you can develop a test case/script that reproduces the error that would be helpful. You may even uncover the error at that point. Have you confirmed the contents of v_xml_new and if on 10g used DBMS_UTILITY.Format_Error_Backtrace to verify the line that threw the error?

Why it is throwing null at last whenever i am running this program
public static void main(String args[])
String str;
try
FileReader fis = new FileReader(C:\\src\\vinaysingh\\xmlreq.xml");
BufferedReader br= new BufferedReader(fis);
do
str=br.readLine();
System.out.println(str);
while(!str.equals(null));
why it is throwing null on last if i am reading any xml fileget the value of string as the value which u
had collected from the string instead of nullWhat? That just doesn't make any sense. At all.
I presume what you're asking is:
How do I read lines from a text file, ignoring empty lines. Especially how do I know when I've reached the end of the file so that I can stop trying to read more lines.
this might help some ...

It never use to do this.JimHdk,
thanks for your reply, but why I could wtach the videos on land mode using the ios 6 and why I can't watch them using this new ios 7 on land mode?

Lately when I sync certain albums to my iPhone, the tracks are duplicated one behind the other so that I have to listen to each song twice. Why does this happen and how can it be fixed?
Very strange behavior. Don't entirely give up on the "Manually Added Items" category ... I have seen things magically appear there even after I've checked and seen nothing there. I think things got real quirky when Apple released iCloud ... I don't remember extra copies of purchases lingering on my iPhone once transferred to my library before that. Sure, if I bought an album directly to my iPhone it would stay on there even after I sync to my library, but if I deleted the album from the iPhone it stayed deleted. Now it seems that there are some phantom copies that come and go with no explanation.
jcburbank wrote:
I've tried deleting the album from both the phone and from iTunes and then redownloading them to both and the same problem occurs.
If you're re-downloading an album to iTunes and your iPhone, that may perpetuate the problem. What happens if you completely delete every copy of the album, then just download to your iTunes library and then sync the album to your iPhone from your library? That should put only one copy on your iPhone.
A few other things to try:
1- Completely sign out of your Apple account on your iPhone, then re-sync to iTunes, then sign into your account on your iPhone again. Maybe throw in a Reset or at least a power OFF/ON somewhere in the middle.
2- Go to Settings/ General/ Usage, then select Music and when you see All Music, swipe your finger across it and tap the Delete button. Before doing anything else, Reset your iPhone. This does not actually delete your music, but seems to clear up some cobwebs left behind (people use this technique to reduce "Other" that swells up over time). -
Why does this ring operation occasionally give an error?
I am using LabWindows/CVI, and I created a low-level ring acquisition. It works normally at first, but if I stop it and start a few times (does not always happen on the first stop / start cycle), then I get the error:
NON-FATAL RUN-TIME ERROR: "Dalsa.c", line 2716, col 13, thread id 0x000012A4: Function imgSessionCopyBuffer: (return value == -1074397014 [0xbff600aa]).
The requested buffer has been overwritten and is no longer available. It occurs on the second line of the following code:
(2715) imgGetAttribute(Sid, IMG_ATTR_LAST_VALID_BUFFER, ¤tRingBufNum);
(2716) imgSessionCopyBuffer(Sid, currentRingBufNum, (uInt8*)pixel_address, FALSE);
I stop my acquisition by :
imgSessionAbort(Sid, &ringBufNum);
Then I unlock my ring buffer, dispose each element, and finally dispose of the buffer list. The next acquisition starts by creating a buffer list, creating and allocating each element, locking the buffer list, and configuring the session to use that buffer list. I am NOT closing the session or the interface, I only do that upon quitting my program. Why do I get this error??
Buffer creation code:
//Create a buffer list
imgCreateBufList(NUMRINGBUFFERS, &Bid);
//Find out how big the buffers should be in memory
imgGetAttribute(Sid, IMG_ATTR_BYTESPERPIXEL, &bytesPerPixel);
bufSize = AcqWinWidth * AcqWinHeight * bytesPerPixel;
//Create the ring buffer
for (i = 0; i < NUMRINGBUFFERS; i++)
//Create individual buffer elements
imgCreateBuffer(Sid, IMG_HOST_FRAME, bufSize, &ringBuffer[i]);
//Now tell the buffer list where these buffers are by populating them into the Buffer List Bid
imgSetBufferElement(Bid, i, IMG_BUFF_ADDRESS, (uInt32)ringBuffer[i]);
imgSetBufferElement(Bid, i, IMG_BUFF_SIZE, bufSize);
//If we are still filling the buffer, this configures the current buffer on the list to move to the next buffer
//If we are configuring the last buffer in the list, this buffer will now loop to the first element when it is filled
bufCmd = (i == (NUMRINGBUFFERS - 1)) ? IMG_CMD_LOOP : IMG_CMD_NEXT;
imgSetBufferElement(Bid, i, IMG_BUFF_COMMAND, bufCmd);
//Locks the buffers in the buffer list
imgMemLock(Bid);
//Configure the session to be a ring acquisition using our buffer list
imgSessionConfigure(Sid, Bid);
Buffer disposal code:
//Unlock the ring buffer memory
if (Bid) imgMemUnlock(Bid);
//Free the ring buffer memory
for (i = 0; i < NUMRINGBUFFERS; i++)
if (ringBuffer[i] != NULL)
imgDisposeBuffer(ringBuffer[i]);
ringBuffer[i] = NULL;
//Free the buffer list
if (Bid) imgDisposeBufList(Bid, FALSE);
Bid = 0;I have made some progress on narrowing the error down, but it still remains a large problem. Error trapping allows me to avoid the necessity of rebooting the system. However, I must still close and re-open my LabWindows application in order to successfully acquire from a ring.
I have narrowed the problem down to the buffer index provided by "imgSessionStatus" : on the acquisition that throws an error, it returns "-1" as the current buffer index. Why is this??
I have modified my program so that I close both the session and the interface when I hit "Stop", and yet I'm still receiving this problem when I attempt to restart the ring acquisition after stopping. I have also started using "imgStopAcquisition" instead of "imgSessionAbort". What could I not be properly resetting after I free, dispose and close the buffers, buffer list, session and interface? Obviously the resource is being properly freed upon application closure, so I must be missing something ... -
Some of the birthdays I have entered in Address book appear in my Ical one day and one year earlier than the date I have given. Eg. I have entered a birthday in Address book as 23 March 2011 and it appears in Ical as being on 22 March 2010. Other names have no problems. There are only some that do not appear with the correct date and year. Why is this? Has anyone found how to correct this strange problem? I have Time Zones ticked.
Bronze2011I'm having this exact same problem, but it's doing it with a bunch of birthdays. I also did 0001 when I didn't know the birth year, so I went back and did a more current year, but they still aren't showing up where they should be...or at all. It's completely bizarre.

I cannot send an email from my iPad 2? No problem receiving, why does this happen? Have tried the suggestions for setting up email and after doing the sync mail through iTunes receiving worked great but still cannot send? Any help would be great!
The fact that you can receive means you have a valid e mail address, and have established the connection to the incoming server, so all of that works. Since the send does not work, that means your outgoing server is rejecting whatever settings you used formthe outgoing set up. Try them again.
Google your particular isp, and ipad and many times you will find the exact settings needed for your isp. Or tell us here, and soneone else may be on the same isp. Some mail services need you to change a port, or have a unique name for the outgoing server.

I created a form, I want the email notices to go to several people. Why is this so difficult? It seems like they have to be a co-author/reader or something? I don't get it
This is crazy! I paid for this service to make it easier to create forms for a company that has had several acquisitions all over the globe. This was supposed to make it easy to create forms hosted on adobe so no matter what happens on all their servers, we would be safe using this forms service until we can integrate all acquisitions and build a permanent web site on a single server. Now I find out that even this is a major issue sending emails to team members, many I have never met so making them a collaborator or even setting up forwarded emails is not something I wanted to do. This service was advertised as simple and easily send notifications to many people. I am now frustrated and thinking this was a waste of money! Why is it like that?
