Description:
development enviroments are as follows: 
jdk:SE1.6
web server: tomcat5.5 
database server:mysql 5.1 (non-install edition)
connector version:5.1

when I write a file in txt format into blob, It works well, but when I try to write a
file in binary format (gif,jpg,jpeg, xls, doc, etc) into blob, exception occurs.

core codes are as follows:
===============================
PreparedStatement st = conn.prepareStatement( "insert into business
(businessname,methodfile) values(?,?)");
BufferedInputStream inn = new BufferedInputStream(new FileInputStream(uploadedfile));
st.setString(1, businessname);
st.setBinaryStream(2,inn,inn.available());

================================
Exception are as follows:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL
syntax; check the manual that corresponds to your MySQL server version for the right
syntax to use near 'm?????k??7°Kdnn??f??í6i!??‘????¤?AH?2<RS$”uo?é?????í
íx??????±????1?%? 
|' at line 1
	

How to repeat:
write a jpeg file into blob,we can repeat the bug.

development enviroments are as follows: 
jdk:SE1.6
web server: tomcat5.5 
database server:mysql 5.1 (non-install edition)
connector version:5.1

Thank you for the report.

Please provide values of max_allowed_packet and size of jpeg file you are trying to
insert.
[29 Sep 8:13] Liu Changsheng
max_allowed_packet :16M
the size of file I try to insert:162K.
actually, I tried many files with different size.but non is successful.

Liu, this should work...

Can you please do the following:
  o Check c/J sources, package testsuite.simple, BlobTest.java and see if it works in
your environment.
  o Try plain Java test, apart from Tomcat and such.
  o Attach full test case (as well as connection string and JRE settings) I can use to
check on problem.
[4 Oct 1:39] Liu Changsheng
OK, I will do it with your instructions, and I will report the result to you as soon as
possible.Thank you.

So Liu, you actually have the same error except that some chars are different now...

I would really like to see "  o Attach full test case (as well as connection string and
JRE settings) I can use to check on problem." now.
[6 Oct 5:02] Liu Changsheng
I have attached the file, which includes jre setting,connction string and source code of
BlobTest.java.
Please check it.
Thanks.
