NotSerializableException with FileInputStream and WL6.1

Hello,
I'm trying to put BLOB into my Oracle 8.1 DB from a session bean on
WL6.1 with following source:
public int insertFile(FileInputStream isf, File file) throws Exception {
Connection con = null;
File file = file
FileInputStream is= isf;
Statement stmt = null;
String sql=null;
try {
con = getConnection();
sql = "INSERT INTO FileTable
VALUES(seq_filetable.nextval,?)";
ps = con.prepareStatement(sql);
try{
ps.setBinaryStream(1, is, (int) file.length());
res = ps.executeUpdate();
}catch (Exception e) {
System.out.println(e);
catch (SQLException sqe) {
throw new CreateException(sqe.getMessage());
I get the following Exception when I'm trying to use the method from my
client app:
java.rmi.MarshalException: failed to marshal
insertValFile(Ljava.io.FileInputStream;Ljava.io.File;); nested exception
is:
java.io.NotSerializableException: java.io.FileInputStream
What should I do? Should I use something else than FileInputStream?
Or is there a better way to store binary data into Oracle?
Thnx,
Jani

Problem with writing and reading using serialization

I am having a problem with writing and reading an object that has another object in it. The purpose of the class is to write a order that has multiple items in it. And there will be several orders. This is for an IB project, where one of the requirements is to utilize a hierarchical composite data structure. That is, it is "one that contains more than one element and at least one of the elements is a composite data structure. Examples are, an array or linked list of records, a record that has one field that is another record, or an array". The code is shown below:
The error produced is
java.lang.NullPointerException

Difference between FileInputStream and DataInputStream

Hai everyone,
I want to know the difference between FileInputStream and DataInutStream.As i am new to this environment i am little bit confused between the two. So i request you to explain the difference with an example so that everything will be clear for me.

FileInputStream is for reading bytes from a file, as is indicated in the API docs: http://java.sun.com/j2se/1.5.0/docs/api/java/io/FileInputStream.html
DataInputStream is for reading java primitives (byte, char, short, int, long, float, double, boolean) through some other stream, as is indicated in the API docs: http://java.sun.com/j2se/1.5.0/docs/api/java/io/DataInputStream.html
If you want to read Java primtives from a file, you'd use them together: FileInputStream fis = new FileInputStream("somefile"); // for reading bytes from the file
DataInputSeam dis = new DataInputStream(fis); // for interpreting bytes read by fis as Java primitives
int ii = dis.readInt(); // dis uses fis to read 4 bytes from the file, and interprets them as a Java int You should probably go through this: http://java.sun.com/docs/books/tutorial/essential/io/index.html

Is there a way to create a year at a glance with detail and print?

Is there a way to create a year at a glance with detail and print?

To do what Dave indicated you need to do, it depends on what version of Acrobat you have:
Acrobat 8: Advanced > Enable Usage Rights in Adobe Reader
Acrobat 9: Advanced > Extend Features in Adobe Reader
Acrobat 10: File > Save As > Reader Extended PDF > Enable Additional Features
Acrobat 11: File > Save as Other > Reader Extended PDF > Enable More Tools (includes form fill-in & save)
I wonder what it will be next time?

I've just found that three movies I've bought from iTunes on on my iPad are not showing up on Apple TV or anywhere other than that iPad. What's up with that and will I lose these films if I reset this iPad?

I've just found that three movies I've bought from iTunes on on my iPad are not showing up on Apple TV or anywhere other than that iPad. What's up with that and will I lose these films if I reset this iPad?

Thanks. The reason this has become an issue is that I recently bought a new Macbook Air that the iPad is not synced to. The one is was synced to was stolen. If I want to sync this iPad to the new Air, won't it be wiped before I'm able to copy these films or am I wrong about that?

Problem with xfce and/or mouse and keyboard

Hi!
Two days ago I've turned on my laptop with Arch and the display manager Slim has frozen immediately. Later on Single-User mode I've uninstalled it. Now in normal mode when I type "startxfce4" everything is showing up, but the mouse and keyboard don't work. I know it's not frozen, because animation of mouse and CPU Frequency Monitor is on.
Strange fact is that laptop is not connecting with the Internet, so now I don't know where the problem is.
It's happening when I start xfce both from user and super user.
Just before those troubles I've updated everything with "pacman -Syu", but I haven't seen anything strange. Also the computer could have been roughly turned off (by unplugging power supply), when was turning on.
Thanks,
Gaba

Sorry for not replying, but I didn't have access to my laptop by this time.
On grub I have only normal mode and 'fallback' mode, so I have result from 'journalctl' from normal mode.
I'm sending the fragment of this file where you can see everything after I typed 'startxfce4' in console:
http://codepad.org/8pYIj8qC
I see that something is wrong, but after some attempts I don't know how to fix this ^^
Edit:
Oh, I forgot to write, that I've tried activate some drivers from 'lspci -k' (there were no "Kernel driver in use:..." in almost every device), but it didn't fi anything.

Problem with JFrame and busy/wait Cursor

Hi -- I'm trying to set a JFrame's cursor to be the busy cursor,
for the duration of some operation (usually just a few seconds).
I can get it to work in some situations, but not others.
Timing does seem to be an issue.
There are thousands of posts on the BugParade, but
in general Sun indicates this is not a bug. I just need
a work-around.
I've written a test program below to demonstrate the problem.
I have the problem on Solaris, running with both J2SE 1.3 and 1.4.
I have not tested on Windows yet.
When you run the following code, three JFrames will be opened,
each with the same 5 buttons. The first "F1" listens to its own
buttons, and works fine. The other two (F2 and F3) listen
to each other's buttons.
The "BUSY" button simply sets the cursor on its listener
to the busy cursor. The "DONE" button sets it to the
default cursor. These work fine.
The "SLEEP" button sets the cursor, sleeps for 3 seconds,
and sets it back. This does not work.
The "INVOKE LATER" button does the same thing,
except is uses invokeLater to sleep and set the
cursor back. This also does not work.
The "DELAY" button sleeps for 3 seconds (giving you
time to move the mouse into the other (listerner's)
window, and then it behaves just like the "SLEEP"
button. This works.
Any ideas would be appreciated, thanks.

I've had the same problems with cursors and repaints in a swing application, and I was thinking of if I could use invokeLater, but I never got that far with it.
I still believe you would need a thread for the time consuming task, and that invokeLater is something you only need to use in a thread different from the event thread.

Problem with installing and running some applications or drivers

When installing and installing some items, towards the end of the installation I get this message:
/System/Library/Extensions/comcy_driver_USBDevice.kext
*was installed improperly and cannot be used. Please try reinstalling it or contact product's vendor for update*
The end result is that some things do not seem to work properly, such as my HP printer. Would anybody have any ideas on how to fix this problem?

Thank you for your response. Originally, I had a problem with Airport and ended up reinstalling Snow Leopard. Since then, when downloading upgrades etc, such as HP printer drivers, iTunes etc., towards the end of the download when its running the script, I get this message: /System/Library/Extensions/comcy_driver_USBDevice.kext
+was installed improperly and cannot be used. Please try reinstalling it or contact product's vendor for update+
Sometimes, the download hangs and is unable to complete. The main problem I've encountered so far with an application is when I use the printer to scan an image via Preview, it's blank: there's nothing there.

Customer Statement with opening and closing balances

Dear Forum,
The users want to generate the Customer Statement with opening and closing balances like the traditional one. The statement now generated gives the list of all open items as on date, but the users want the statement with opening balances as on the date of the begining of the range specified and the closing balance at the end of the period for which the statement is generated. Is there a way to generate the same from the system.
Thanks for the help.

You can use the program RFKORD10 with correspondance type SAP06 for your company code
This program prints account statements and open items lists for customers and vendors in letter form. For account statements, all postings between two key dates, as well as the opening and closing balance, are listed.

Is Verizon going to acknowlege the problems with FIOS and Windows Vista

For months now, I have been reading the numerous problems Fios internet customers are having with Fios internet/Actiontech Router and Windows Vista and there has been no acknowledgement by Verizon of this current major issue.
I have also experienced the exact same issue for months now since I switched to Verizon FIOS internet. Previously I had Comcast HSI using my Windows Vista laptop. I had their service for over a year and I NEVER has a problem with the Windows Vista globe icon disappearing and loosing internet connection. The Globe always stayed on and never went away and I never lost connection when I had Comcast
I had Verizon FIOS installed last September with my Windows Vista computer and my wireless internet connection started to drop from day 1 and it has been a daily occurrence for over 5 months now. It has gotten so bad, I have had to hardwire my laptop to to be able to use the internet uninterrupted.
This is what daily scenario is:
When I turn on my laptop(with Windows Vista, I can initially get full internet access(with the globe on and it says "Local and internet). After about 10 minutes or less, the globe switches to "local only" and I can still get internet access. After another 5 or so minutes, a large X covers the globe and I lose internet connection entirely. The actiontech router wireless signal is no longer listed as one of the wireless networks. The only way for me to regain internet access is either to restart my laptop or reboot the actiontech router.
Numeorus posts here, over by DSL forums(Broadband Reports),Microsoft's website and a few othere websites detail this issue.
I am extremely shocked and surprised that Verizon has not tried to fix this issue by working with both the makers of the Actiontech Router as well as Microsoft to find out what the problem is and how to fix it.
I would just like to reiterate I strongly believe this is primarily a FIOS internet issue since I previously had Comcast HSI for over a year with the same Windows Vista laptop and I NEVER had that problem. Also, I can connect to my neighbors wireless connection(she uses Comcast HSI) and when I do, the globe stay on all the time on my computer and the internet does not lose connection.
I know that there are a couple of Verizon employees here. Please tell the higher ups who handle FIOS internet that this is a major issue that needs to be resolved as soon as possible.
P.S: Please don't tell me to go by my own router because then, I will have to deal with the issues of setting it up to work with Fios TV and the related VOD, widgets, remote DVR compatability issues to deal with. I don't think I can deal with the additional headaches.

FIOS is short for fiber optics. fiber optics is different technology than DSL.
With that said, if you search the Microsoft databases for vista issues with fiber optics, (CURRENTLY THERE IS ONLY ONE PROVIDER OF FIBER TO THE HOUSE, that being Verizon, so yes you can also search Vista issues with verizon and\or fios) and you will find that Microsoft already acknowledges this issue with their software. AND they offer you a fix.

Progams that work with Alltel and Suddenlink are no longer working with VERIZON (IRC)

I have worked this issue TO DEATH already and am getting FED UP!
I have been polite and nice and called customer support to get very short and not very explicit answers to this issue.
Complaint #1: When I call technical support and ask questions more complicated than " How do I plug in my computer?" they inform they are transferring me to TECHNICAL support. Okay so who did I call in the first place if not tech support.
Problem: IRC ( Internet Relay Chat) Is one of the main things that I enjoy doing online. Some do games, some do work. I do it all through my little IRC program. When I was with Alltel and had my little blackberry pearl. I could even get onto irc just fine that way. Getting on via a cell phone is kind of a pain. Small keyboard and lots of typing isn't my idea of that relaxing but.. okay whatever at least I could get on. Since Alltel became Verizon I was told to upgrade my phone to the brand new Blackberry Curve. Well now IRC didn't work. I upgraded to the LG Vortex. Now it works on my phone. So I upgraded my wireless card too and IRC worked just fine for a long time. NOW we are back to the same old same old.
For those of you not familiar with the program just wiki it. I have been told by NUMEROUS customer support reps that this program is not being blocked so this is the list of things I went through to make sure it was indeed NOT me or my computer.
Step 1: System restored before most recent updates to the last date that it was working.
NO GO
Step 2: Disabled firewall and virus software temporarily and even turned down my security on my browser
NO GO
Step 3: Re updated my computer and updated my firmware on my MIFI2200 card.
No go
Step 4-7 Called customer Support
NOPE.
Still waiting. I am paying for a service that is not providing. My entire family was with Alltel and is now with Sprint. I just keep asking myself why am I still with Verizon when all we ever do is fight. I hate to admit it to the kids but I think it's time for a divorce from you if we can't get this issue resolved. Before upgrading to these devices I even asked store reps if irc programs would work and they assured me " OH YES! With these new upgrades things will be better than ever!"
I realize to some this seems like not a very big deal, but when I am paying for a service so that I can come home relax, maybe take a few art commisions while chatting on irc and all the sudden I either can't use it or can use it when I couldn't before it's amazingly frustrating. I have taken my computer over to other people's houses to see if turning my security all the way back up as well as my firewall made a difference, but on any provider OTHER than verizon I can connect just fine.
Tell me WHY Verizon. Tell me why you either can't fix this.. or won't fix this.
Security issues? That's my problem. If I want to connect to a DNS server based program that connects via different ports.. that should be MY decision. You should NOT get to make that choice for me.
It's amazing I went to the customer support for IRC and they told me that Verizon doesn't allow you to use IRC. I have checked NUMEROUS boards and discussion forums only to have them tell me that VERIZON does NOT allow you to use IRC. However when I talk to Verizon they say " No it must be you.. " Well I am not taking that excuse anymore. I've done my share of work on this problem. Now it's your turn. Sorry to be rude.. but I paid for the mIRC program, and take artwork commisions over it as well. I probably pay more for verizon's service than I would with sprint (so says the rest of the family).
Please give me some real answers and real tech support.
Thanks for any help.

I choose option 3. The moment I talk to them about anything more complicated than the bare basics of getting connected they tell me they will transfer me to " tech support." Very frustrating lol. I always wonder who I was on the phone with prior to that because it says Tech support but clearly there must be different levels of their support lines. Sometimes I get someone who will talk and work with me, but generally I get someone who says " Okay I have down your issue and I'll pass it along.." then they hang up. However I have been transferred twice in one sitting from "tech support" to Tech support. So I dunno. I think they don't have an answer and so they run me in circles.

Outlook 2011 no longer syncing with iCal and contacts

I have installed Yosemite recently on my Macbook Pro. I run MS Outlook 2011 for professional reasons. Until now, syncing with my Android phone worked (almost) fine, using a nice app called SyncMate. For a few days now (not sure it is linked to installing Yosemite though) new data on my outlook calendar and address book no longer appear on my phone after syncing. After checking I realized that Outlook is actually not syncing any more with iCal and Contacts, so of course the syncing with the phone cannot work. How can I resolve this ?

facing the same problem, it was syncing prior to my upgrade to Lion. have you managed to find a solution?
