Problems with writing to Pointbase
Hi..
I'm trying to write a java program whose job it is to read and write from a Pointbase database. Reading from the database works fine, but every time I try to do an "insert into"-sentence I receive the following error:
java.sql.SQLException: Expected to find ")" instead found "OCT" at position 31.
The error code returned is 10006.
Now I'm pretty sure this is due to file permissions (I'm running Fedora Linux Core 4) but I've tried to set persmissions on different files and even the entire catalouge which contains Pointbase recursively, but it still won't write to it. I've also started the server as root (which is the mode I installed Pointbase in), but to no avail. I'm writing my program in NetBeans 4.1. I've even tried to reinstall the database.
Has anyone experienced the same problem ?
What is the exact problem? Your description:
java.sql.SQLException: Expected to find ")" instead found "OCT" at position 31.
doesn't sound like a permission problem. Can you post the complete stack trace?

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

Problem with writing continuous data to excel using using Report Generation vi's
Hey Everyone,
I am trying to read the data from DAQ and write to excel continuously using Report Generation vi's.
But when I run the VI, it writes only one interation of the while loop (gathering data from DAQ continuously) and doesn't append the data into the same file when I run it again after stoping the VI.
I have attached the VI i created. Please let me know if you have any idea to solve this issue.
Thanks
Attachments:
sample 5.vi 35 KBThere are two problems with your VI. First, the basic logic of writing/appending to a file (Excel, TDMS, anything) should go something like this: Open the file, position yourself at the end of the file, then, in the loop, acquire data and write it to the file until you are finished with data acquisition. When you exit the acquire/write to file loop, then close the file. In particular, the opening and the closing of the file should not be inside the loop.
As others have pointed out, writing to Excel might not be optimal, particularly if you are acquiring data at a high rate (and would therefore be writing a lot of data). We actually use Excel in our data acquisition routine, mainly reading from a WorkSheet to get the parameters of a particular stimulus, but also writing the outcome of the response to the stimulus. As it happens, our "acquisition rate" in this example is on the order of several samples per minute, so there's no problem using Excel (we also sample 16 channels of analog data at 1 KHz -- this gets written as a binary file).
Second, if you really do want to use Excel, use the (existing) Excel file to which you want to append as the "template" argument of the New Report function. Then use the Excel Get Last Row function to position yourself at "end of file", as noted above.
Good Luck.

1) It does not permit me to switch on a String. How do I solve that?
2)How would I throw an exception (IO) within actionperformed?
3)Generally, if cut it down to everything except the writing to a file part, the actionperformed script causes an error... why?
Thanks in advance.
And sorry for the relative lameness of my question...
---abe---Thank you very much. That did solve almost all the problems that I had...

Now that code above produces two errors. First of all.
local trim();produces the error:
Syntax error, insert "AssignmentOperator ArrayInitializer" to complete ArrayInitializerAssignementSecondly, if I take that into comments, the line
setLabel(m.get(LineField.getText()));Produces the error:
The method setLabel(String) in the type Personnel is not applicable for the arguments (Object)If anybody could help me solve these, I would be sincerely thankfull.
Now, before anybody asks as to why I want to trim the String in the first place, it is due to the fact that I compare it to another String that is without whitespaces. Thus the field that DOES have whitespaces was preventing me from launching into the if loop:
if (sortHelp[1]==local) {
flag=true;
(within actionperformed) Or at least that's my explanation as to why the loop never launched. If it is wrong, can somebody please explain?)
I apologize for the horrible indentation and lack of comments. This is an unfinished version.. I'll be adding the comments last (won't that be a joy), as well as looking for things to cut down on and make the program more efficient.
Anyways,
Thanks in Advance,

Problems with writing files after migration
I migrated my old Pismo HD to a new MacBook Pro (a frustrating process which I eventully had to accomplish using a clone of the Pismo disk and a firewire drive) and have a couple of issues.
The most troublesome at the moment is a problem with Safari. It will not let me download files when I am operating as the migrated user, although it will allow downloads if I log in as the user I established during initial setup.
I am also having trouble using Spotlight or the Find utility. Most of the time when I use these, the computer either goes into a kernel panic or grinds away for minutes and never finds anything before I give up in frustration. However, the find function on the top right of finder windows works well.
Any suggestions welcome, thanks!
Various Mac OS X (10.4.8)Thanks for the suggestions. I had already tried the "Get Info" route with Safari.
The "sudo mdutil -E /" seems to have worked for Spotlight. I did get an error message saying that my volume was not indexed; however, it seems to work now. (I'll get around to indexing the disk eventually.)
I repaired the permissions on my startup disk from the install CD, but the Safari problem is still there (same problem with Firefox).
Any other ideas most appreciated. -

JME Socket File Transfer - Problem with writing file
Hi everybody, i'm trying to code a P2P app for a school project and i have a problem when trying to write to a file.
This method recieves a file form a Socket Server computer that tries to send me a file to the mobile client.
The method recieves the IP adress (String add) and the port of the server.
Also, i would like to know about the buffer(byte) size.
This codes runs well in emulation, but it doesn`t write to a file.
And the main problem is:
"When i run this in the mobile, the file is created in the cellphone memory with a size of 0kb."
The server code was tested with a computer client and recieved the file succesfully.
The server recieves de socket connection form the cellphone without problem.
public void recibirArch(String add, int port) throws Exception {
try
recibArch.setText("Espere por favor...");
long start = System.currentTimeMillis();
int bytesRead;
int pasos = 12;
int current =0;
SocketConnection sock = (SocketConnection)Connector.open("socket://"+add+":"+port);
byte [] mybytearray = new byte [1024];
InputStream is = sock.openInputStream();
FileConnection fc = (FileConnection) Connector.open("file:///"+saveRoot+"5letras.txt",Connector.READ_WRITE );
if( !fc.exists() ){
fc.create();
} else
fc.truncate(0);
DataOutputStream fos = new DataOutputStream(sock.openOutputStream());
bytesRead = is.read(mybytearray,0,mybytearray.length);
current = bytesRead;
while ((current = is.read(mybytearray)) != -1)
fos.write(mybytearray, 0, current);
fos.flush();
current+=bytesRead;
long end = System.currentTimeMillis();
fos.close();
sock.close()
catch(Exception err)
String error = "ERROR: " + err.toString() + "\nDescripción: "+ err.getMessage();
System.out.println(error);
txtLog.setString(error);
Edited by: xtylo on Sep 30, 2008 10:56 AMThank you Tunde for looking at my issues!
The file size is not an issue here. We tested with empty files or files with smaller than 1KB sizes. They all showed problem. The frequency of file transfer shouldn't be a problem either. Through some user interaction on front panel, a couple of files will be transferred. That's basically how often the file transfer occurs.
Interestingly enough, I replaced the copy.vi with a subvi I created using DOS command with System Exec.vi and the issue of copying files went away. My co-worker tested on both XP machine and Windows 7 machine. The DOS command worked fine thru Lavview's System Exec.vi. I think I can take that as a work-around if we can't figured out why copy.vi wouldn't work. Still, it would be nice to know why it doesn't work.
Now I'm still facing some issues with the usage of Check If File or Folder exist.vi. Sometimes it can detect the existing files and sometimes it doesn't.
Thanks very much! -
Problem with writing to a socket channel
My situation is thus:
I have a SocketChannel connected to a remote telnet server. I am using a keylistener to listen for the enter button on a jtextarea in order to send the contents of that jtextarea to the remote telnet server via socketchannel.write
The problem is that when I have the code to do this located in a keyReleased event listener, it works fine. However, for other reasons, I really need it to be in a keyPressed event listener, and it fails silently when I put it in one.
I have code both before and after the part of the listener that calls socketchannel.write that executes properly, and some debug code that shows that i am sending the bytes that I think that I'm sending, and the socketchannel.write call returns the correct integer to agree with the number of bytes I'm trying to send, but the remote server never actually receives those bytes. It would automatically send back a response if it did, and even beyond that, I get timed out for inactivity by the remote server even if i continuously hit enter to send data.
The keylistener i'm using is a class extended from keyadapter. I can literally flip the function signature back and forth between keyReleased and keyPressed, and it works absolutely perfectly with keyReleased, and everything but the socketchannel.write works perfectly with keyPressed. I am at a complete loss as to why it works with one, and not with the other.
Any insights?
Thanks in advance.I have found an answer elsewhere.
The problem was that, with keyReleased, the actual stroke of the enter key was being recorded before the text was being sent, so it had a \n on the end of it.
The game required a terminator in order to be able to process the data I sent, and keyPressed wasn't generating one. -

Problem with writing code from template based file
Hey there! Thanks for taking a look at this:
I have a page that I created New> From template.
I'm in Split view and I'm manually going in and placing my cursor where I want to add some content. Ive tried writing a <br> tage and inserting a Div.
I'm inserting this code right before the closing <div> tag that my editable region ends, its clearly in the right spot, within my editable region in the template, but I'm getting an error from dreamweaver that says it's not. This seems to only be happening when I edit the code directly. If I insert code through the menu's in design view I don't get this message.
I'm using CS5 on a Mac
What do I Do?> making this change would require changing code that is locked by a template
> or a translator. The change will be discarded
This 'generic' error message happens as follows -
1. You open a page that is controlled by a Template
2. You make a change to that page, forcing the template engine to run through the page looking for things to potentially change (this is normal)
3. While doing this scan, the Template engine finds an unspecified number of coding errors and attempts to fix them
4. If it tries to fix an error that is a) in a non-editable region of the page, or b) in a Library item, it cannot do so, and throws the error
So - the first questions are these:
1. Does the template validate when you go here - http://validator.w3.org - and paste the code from the page into the Direct Input tab?
2. Do the Library items contain <html>, <head>, or <body> tags?
If the answer to either of those is "yes" then we will have to see the page and the code to guide you further. -
Having a problem with writing pivoting query.
Hi All,
I have a query with one input parameter. It gives different result based on the input provided.
For example
1. If i give input as date1 the output would be as follows.
Col1 Col2 Col3
name1 v1 10
name1 v2 14
name2 v1 15
name3 v3 202. If i give input as date2 the output would be as follows.
Col1 Col2 Col3
name2 v1 14
name2 v2 10
name3 v1 8
name3 v2 14
name1 v1 10
name1 v2 34
name1 v4 23
name1 v5 10
name4 v1 12
name4 v2 14
name4 v4 18
name4 v5 20
name5 v1 14
name5 v2 10and so on for diff inputs, I get diff output.
Now, I am trying to write a query which would give me the pivot data on the outputs shown above.
For Example
1. For the first output on the top, the pivot query should return the data as follows:
name1 name2 name3
v1 10 15 0
v2 14 0 0
v3 0 0 202. For the second output on the top, the pivot query should return the data as follows:
name1 name2 name3 name4 name5
v1 10 14 8 12 14
v2 34 10 14 14 10
v3 0 0 0 0 0
v4 23 0 0 18 0
v5 10 0 0 20 0and so on...
I would be greatly thankful for any kind of input provided since.
Regards
SapanHi Frank,
Thanks for your response, I did have a look at the thread which had the options for both static as well as the dynamic pivoting.
But as you said this scenario needs a dynamic SQL. The only constraint is, I need to plug in the SQL into HTML-DB and spooling would not be feasible. That's the reason I am trying to frame a query around the current query which gives me the base data to be pivoted. I am also keeping my options open on coming up with PL/SQL block, which can integrate well with HTML-DB.
Any thoughts/suggestions would be helpful.
Thank you. -
I have a problem with writing measurement to excel after 15s do-while data acquisition
Dear Sir/Madam
Currently, I am trying to write a 15 seconds of measurement into an excel file. The 15 seconds measurement is done by do-while function.
But unfortunately, after the 15 seconds measurement, not all the data can be written to the excel, only one reading was successfully written.
The Write to Measurement to File is outside the frame of do-while loop.
Could you please tell me how to solve this problem?
Many thanks for your help.
kind Regards
Ken
Solved!

The output tunnel that you have wired to your Write To Measurement File that is on your While loop.

File upload: problem with writing uploaded file to server-harddisk
Hello,
according to the example in the File upload tutorial, I tried to save an uploaded file to disk, but it didn't work (and also no messages / exceptions were thrown).
The Javadoc for the function uploadedFile.write(filename) says that if the file should be written in an other directory than the servers' tmp-directory, the server.policy has to be adjusted.
The following line is already included in my server.policy:
permission java.io.FilePermission "<<ALL FILES>>", "read,write";
So I have two questions:
1) Where can I find the servers' tmp-directory?
2) How should the sever.policy permission code look like?The File Upload tutorial at http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/file_upload.html has you save the uploaded file to disk. It also gives this information:
The server holds the uploaded file in memory unless it exceeds 4096 bytes, in which case the server holds the file contents in a temporary file. You can change this threshold by modifying the sizeThreshold parameter for the UploadFilter filter entry in the web application's web.xml file. For more information on modifying the web.xml file, see the last section in this tutorial, Doing More: Modifying the Maximum File Upload Size.
In cases where you want to retain the uploaded file, you have three choices:
* Write the file to a location of your choosing, as shown in this tutorial.
* Create an UploadedFile property in a managed bean and set it to the component's value before you exit the page (as in the button's action method).
* Save the file to a database.
By default, the File Upload component can handle files up to one megabyte in size. You can change the maximum file size by modifying the maxSize parameter for the UploadFilter filter entry in the application's web.xml file, as described in the last section in this tutorial, Doing More: Modifying the Maximum File Upload Size. -
