Hi,
I am using the following piece of code for establishing the connectivity



However i am getting the following exception when i run the program

I tried to print the SQL error code and it comes to be 0.
I am not using any query or anything this exception occurs when i call Drivermanager.getCnnection().

I am afraid you will have to check your private messages again, Adithya.

Hi
We generally dont use our last name in india since its most of the time our fathers name So i wud still be preffered to call Adithya NN. If it still violates your naming policy I am afraid i will have to leave JavaRanch.I dint expect this kind of insensitivity from your end

Thanks & regards

28.4.5.3.9: When using gcj an java.io.CharConversionException is raised when working with certain character sequences.

This is a known issue with gcj which raises an exception when it reaches an unknown character or one it cannot convert. You should add useJvmCharsetConverters=true

It's not a case of insensitivity, but of bitter experience with fora where people use pseudonyms only. The atmosphere can become unpleasant and we have found that enforcing the naming policy strictly helps maintain a friendly atmosphere here, even though (and we are sorry about that) it may inconvenience a few people.

It would not be appropriate to continue discussing the naming policy here, but you are welcome to go through the "Javaranch" forum where that sort of thing is normally discussed.

As to the display name, note that you're free to choose any name you like. It doesn't have to be your real name, it just has to sound like a real name, and have a full first and last name.
 
I agree. Here's the link: http://aspose.com/file-tools
