How to send byte array and String values to servlet from Swing application
Hi all,
I am new to swing, servlet, and socket connection.
I have swing application to draw images and some input data. I dont know to send to server.
byte[] buf = baos.toByteArray();
URL servletURL = new URL("http://10.70.70.1:8080/servlet/SaveImage)
URLConnection conn = servletURL.openConnection();
conn.setDoOutput(true);
BufferedWriter out = new BufferedWriter( new OutputStreamWriter( conn.getOutputStream() ) );
out.write(buf&a=aaaa&b=bbbbb);
out.flush();
out.close();
can I do like this. Strings are received in server side perfect. but i cant get byte array data. Please help me.
Thanks in advance.

In your myservlet:
response.setContentType("image/jpeg");
then write your image date via ImageIO that uses response output stream.

How to send byte array of image with 300dpi.
Hello fiends
i am making an application in which i have to send the byte array of an image with 300dpi.
so i am using image snapshot class for that and use that code.
var snapshot:ImageSnapshot = ImageSnapshot.captureImage(cnvParent,300);
var bdata:String = ImageSnapshot.encodeImageAsBase64(snapshot);
but when i send that bdata to php end using httpService.The size at other end of image increases surprisingly.i means it will increase its actual height and actual width.so is there any way to overcome this increase in size when i bitmapped image at 300 dpi?
if there any way then please tell me.waiting for your reply.
Thanks and Regards
Vineet OshoThanks david for such a quick reply.the link is really helpful.So we have to calculate the screendpi thruogh our code and then set the height and width of image.is there any simple way to sort out my problem.i just want to print my image at 300dpi but i am using image snapshot class so its taking the snap of my container(image) and save the image at 96 dpi which is dpi of my screen(monitor).so is there any way or any class in flex through which i got the image at its original dpi.i am not stick on 300 dpi but i m getting image from backend through xml at 300dpi.thats why i want the byte array i am sending should be at 300dpi.i am totally confused now.so please help me.
Thanks and regards

How to send an array of values to stored procedures in java
can anyone tell me how ican send a two dimensional array of string values can be send to a data base at one go.
actually i am a java developer and the technolgies i am using are servlets and java data base connectivity(JDBC). the oracle developer with whom i have worked has created aprocedure for taking the two values. she has created a record and she has used the the record as an in parameter to the procedure. that particular record has two columns and i need to send it as a two dimensional array.The PL/SQL webservice functionality in Oracle WebServices can expose PL/SQL procedures as webservices.
If you are just looking for Java solution, check out JPublisher, which maps PL/SQL stored procedure into JDBC programs. -
How to split the blob byte array and insert in oracle
how to split the blob byte array and insert in oracle
I am having a string which is of more than lenght 4000 so i am using BLOB datatype as input to get the string.
need to split the blob in oracle and store in the different column
The string is of bytearray i need to strore it in each column based on the byte array.this will be my input i need to split the above and store it in different columns in a table.
for spliting say
Column1 -1 byte
Column2-3 byte
Column3-5 byte
ColumnN-5 byte
Table will have corresponding data type
Column1 - number(10,2)
Column2 - Float
Column3 - Float
ColumnN-Float
here Column2 datatype is float but it will always have 3 byte information.
where as Column3 datatype is also float but it will always have 5 byte information.
Say N is Column 120 -
What is the best way to convert a cluster into byte array or string
I'm writing a program that sends UDP packets and I've defined the data I want to send via large clusters (with u8/u16/u32 numbers, u8/u16/u32 arrays, and nested clusters). Right before sending the data, I need to convert the clusters either into strings or byte arrays. The flatten to string function is almost perfect for this purpose. However, it's appending lengths to arrays and strings which renders this method useless, as far as I can tell.
As I have many of these clusters, I would rather not hard code the unbundle by names and converting/typecasting to byte arrays or strings for each one.
Is there a feature or tool I am overlooking?
Thank you!deceased wrote:
Flatten to string has a boolean input of "Prepend string or array size" ... The default value is true.
That only specifies if a string or array size should be prepended if the outermost data element is a string or array. For embedded strings or arrays it has no influence. This is needed for the Unflatten to be able to reconstruct the size of the embedded strings and arrays.
The choice to represent the "Strings" (and Arrays) in the external protocol to LabVIEW strings (and arrays) is actually a pretty bad one unless there is some other element in the cluster that does define the length of the string. An external protocol always needs some means to determine how long the embedded string or array would be in order to decode the subsequent elements that follow correctly.
Possible choices here are therefore:
1) some explicit length in the protocol (usually prepended to the actual string or array)
2) a terminating NULL character for strings, (not very friendly for reliable protocol parsing)
3) A fixed size array or string
For number 1) and 2) you would always need to do some special processing unless the protocol happens to use explicitedly 32 bit integer length indicators directly prepended before the variable sized that.
For number 3) the best representation in LabVIEW is actually a cluster with as many elements inside as the fixed size.

How to add byte[] array based Image to the SQL Server without using parameter
how to add byte[] array based Image to the SQL Server without using parameter.I have a column in table with the type image in sql and i want to add image array to the sql image column like below:
I want to add image (RESIM) to the procedur like shown above but sql accepts byte[] RESIMI like System.Drowing. I whant that sql accepts byte [] array like sql image type
not using cmd.ParametersAdd() method
here is Isle() method contentSQL Server binary constants use a hexadecimal format:
https://msdn.microsoft.com/en-us/library/ms179899.aspx
You'll have to build that string from a byte array yourself:
byte[] bytes = ...
StringBuilder builder = new StringBuilder("0x", 2 + bytes.Length * 2);
foreach (var b in bytes)
builder.Append(b.ToString("X2"));
string binhex = builder.ToString();
That said, what you're trying to do - not using parameters - is the wrong thing to do. Not only it is insecure due to the risk of SQL injection but in the case of binary data is also inefficient since these hex strings are larger than the original byte[]
data. -

HOW TO SEND THE REPORTS AND THROUGH XI TO NON -SAP SYSTEM
Hi Experts,
I want to know how to send the reports and smartform through xi to another system. All the post blogs are just explaning only about the FILE-TO-FILE, FILE-TO-IDOCS scenarios only.Hi,
XI is the middleware that to be used to transfer the data between various systems and even you could design the Business Processes with it.
In R/3 the smartforms, are generally converted to PDF and then have to send it across to Non SAP systems. Similarly you can convert the smartforms to pdf format and keep it on application server. XI will pick up that pdf and will send it to Non SAP system either as mail or as an attachments.
ABAP reports are normally used to re-present the data. If you need to transfer this data across the Non SAP systems then you have the IDOCs to be generated, RFC or ABAP Proxy to integrate this data with Non SAP system.
XI is not restricted only upto file to file or file to IDOC scenarios. It have enormous capabilities to involve various Business Processes as well integrate various SAP or Non SAP systems.
If need anymore specific details, please let us know.
Thanks

How to avoid the Amount and Date values for VOID Cheques
Hi All,
I had created a two window i.e For Amount and Date. If I process the cheque the Amount value and Date should not trigger for VOID CHEQUES.
Can any one tel me how to avoid the Amount and Date values for VOID Cheques
Your help will be greatly appreciated.
Regards
YathishHi,
I dont know which tablel you are referring to, is it PAYR table and the field VOIDR?
If a cheque is voided, it would have a reason and it is stored in VOIDR field of this PAYR table.
Check if the field VOIDR is filled, if it is filled, do not print the amount and date.
Regards

Unable to connect laptop to wireless network
My MacBook Pro will not connect to my wireless network, but my iPad does so I know it must be a problem with my computer rather than the network. Any suggestions? I'm not sure if there is some obscure setting that I need to change.
