Hello.
I have recently tried upgrading the MySql connector for my servlet
from 2.0.4 to 3.0.9. I have found a minor limitation in 2.0.4 and was
hoping that 3.0.9 would fix it. However, now I am having a serious
problem with the latest connector. During login, it seems to me that
when validating the password, which is stored as a byte array in the
database, the MySql connector is passing back the password info as a
Byte. The exception I receive is the following:
Error while processing request: java.lang.Illeg alArgumentExcep tion

However, when I trace through the code, I find that it is crashing
when it reads the password field by mapping it as a String rather than
a BYTE.
It crashes in the following code:
Object val = recs.get(j);
....
if (val==null)
f.set(answers[i], null);
....
else if (val instanceof byte[]) {
Object o = null;
try {
ObjectInputStre am in = new ObjectInputStre am(new
ByteArrayInputS tream((byte[])val));
o = in.readObject() ;
in.close();
}
catch (Exception e) {
if (!(answers[i] instanceof LogRecord))
throw e;
}
f.set(answers[i], o);
}
else
f.set(answers[i], val); <--- CRASHES HERE
The problem is that it should get caught in the else if just above the
last else. Now, the old mySql connector works fine, so I am curious
if something happened in the newer version. This is just a strange
problem. Does anyone have any ideas as to where to look to fix it?
Thanks in advance

I need more Java code.
What are f and answers declared as? What does the f.set() method do?
I need to see the query, and the code where you are getting it out of the
database.

I have a java program that receives data via sockets from a C program.
The java program has to recieve the data in byte format. I need to

there a way to have a byte datatype in c?

I have a project that creates a SqlDataAdapter and uses its Fill method to

However, I need to be able to determine the size of the varchar fields that

The obvious answer appeared to be to check the DataColumn.MaxLength

If I have a text file more than 8 byte or upto 100 byte, how can I insert the data of that text file into mysql table. As per as I am concern there is not any datatype more than 4 byte in character. 'LONGTEXT' datatype can store upto 4 byte and maximum length of 4,294,967,295 characters.
But I need to store upto 100 bytes. How can I do this?
Or is there any other database server which can solve this problem?

Hi,
I am trying to get (and transfer over ASP.NET) some encrypted data
from some MySQL fields. Since the data contains many unicode
characters, I tried to get the data as a series of ASCII values,
transfer those numeric values over ASP.NET. I had no problem doing
this on my local computer, by getting the field with "cast(field as
BINARY)" so that on ASP.NET I have a byte array.Then send every
field of array over ASP.Net.
