MySQL server configuration issues - java

As my topic says, the max_allowed_packet variable is not working.
I have a project in eclipse which loads csv-files up and store them into a mysql database through a servlet. For files smaller than 1M it works fine.
But my file is 95Mb big, and i have increase the 'max_allow_packet' variable in the my.ini file in the section [mysqld] up to 500M.
But it doesen't work. Eclipse gives my the same error.
Please take a look at this two pictures:
ECLIPSE
my.ini
[mysqld]
....
Thanks for help
*****EDIT*****
com.mysql.jdbc.PacketTooBigException: Packet for query is too large (190104490 > 26214400). You can change this value on the server by setting the max_allowed_packet' variable.

Ok, now i have set the varibale also in de [client] section of the my.ini file. Seems to be work.
But now i got this error code:

I've set the varibable like this:
[mysqld]
innodb_file_per_table=1
innodb_buffer_pool_size=1GB
innodb_log_file_size=128M
innodb_log_buffer_size=8M

Check points
Have you restarted mysql service after changing my.ini?
Run query SHOW GLOBAL VARIABLES LIKE 'max_allowed_packet' and see the value. It should be 500MB (Equal bytes)
If the above query does not return 500M, then try running SET GLOBAL max_allowed_packet = 500 * 1024 * 1024. Then repeat step 2.
If value is shown as 500 M repeat your file upload.
If still problem persists, then it could be like mysql is looking at different variable.

write object to file from servlet

I'm trying to write to file from a servlet and i'm not really sure if the path i gave in the xml file is wrong or something else
private List<User> getUsersList() throws IOException, ClassNotFoundException{
List<User> users=new ArrayList<User>();
FileInputStream fis=new FileInputStream(f);
ObjectInputStream ois=new ObjectInputStream(fis);
User u;
while(true){
if((u=(User) ois.readObject())==null)
break;
else{
users.add(u);
}
}
ois.close();
return users;
}
that's the method i use to read from file where
private final String usersfile;
private ArrayList<User> users;
private File f;
public UsersService(String filename) throws ClassNotFoundException, IOException {
super();
usersfile=filename;
f=new File(this.usersfile);
if(!f.exists()){
f.createNewFile();
}
users= (ArrayList<User>) this.getUsersList();
}
and the xml param
<context-param>
<param-name>userslist</param-name>
<param-value>/users.txt</param-value>
</context-param>
and that's the exception

Getting error while receiving Object in restful webservice

Code i used to convert my reg_be obj to is inputstream.
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(baos);
oos.writeObject(reg_be);
oos.flush();
oos.close();
InputStream is = new ByteArrayInputStream(baos.toByteArray());
Then i pass this inputstream to webservice.
My web service code is
public String getText(#Context HttpServletRequest request) throws IOException {
//
Registration_BE reg_be=new Registration_BE();
InputStream in=request.getInputStream();
ObjectInputStream ois = new ObjectInputStream(in);
try {
reg_be=(Registration_BE) ois.readObject();
} catch (ClassNotFoundException ex) {
Logger.getLogger(CustomerregistrationResource.class.getName()).log(Level.SEVERE, null, ex);
}
}
In web service inputstream is not receiving properly why?
this method is working for my image inputstream.But for this object it is not working why? plz help me..

Avoid using java serialization for web services - this is very limiting and not advisable.
Use JSON/XML as transport format instead, which are language and platform independent.

generating a JavaAbstractMethod exception

i've written this code for adding photos to database and i'm not much into web application
so please help me out
// obtains input stream of the upload file
inputStream = filePart.getInputStream();
}
Connection conn = null; // connection to the database
String message = null; // message will be sent back to client
try {
// connects to the database
DriverManager.registerDriver(new com.mysql.jdbc.Driver());
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/opmdb", "root", "sourabh");
// constructs SQL statement
String sql = "INSERT INTO photos (userId, photo) values (?, ?)";
PreparedStatement statement = conn.prepareStatement(sql);
statement.setString(1, userName);
statement.setBinaryStream(2, inputStream);
here it is telling the error i've also used setBlob but the error remains the same
Exceptions and stacktrace is
java.lang.AbstractMethodError:com.mysql.jdbc.PreparedStatement.setBinaryStream(ILjava/io/InputStream;)V

change your code statement.setBinaryStream(2, inputStream);
to
statement.setBinaryStream(2, inputStream,file.length);
'setBinaryStream' method need 3 parameteres,add your file length in this method

getting null pointer exception while instantiating ServiceClient

I have made a client where i am creating a new object of ServiceClient. My code is:
private ServiceClient getClient(String action, String eprType){
String webinfFolder = request.getSession().getServletContext().getRealPath("/WEB-INF");
try{
if(wsSecurityEnabled){
configContext = ConfigurationContextFactory.createConfigurationContextFromFileSystem(webinfFolder, webinfFolder + "/conf/axis2.xml");
serviceClient = new ServiceClient(configContext, null);
}else{
serviceClient = new ServiceClient();//Here i am getting nullpointerexception
}
}catch(IOException ioe){
ioe.printStackTrace();
}
targetEPR = new EndpointReference(eprType);
serviceClient.setOptions(getOptions(action));
serviceClient.addHeader(getUserNameHeaderElement());
System.out.println("Client Created");
return serviceClient;
}
Since my wsSecurityEnabled is false it comes to this code serviceClient = new ServiceClient();
and here i am getting nullpointer exception as:
java.lang.NullPointerException
