MySQL problem

[Paul Cullen]

I have a application using a MySql database. The application retrieves information and prints it out. That bit is all working. But the problem I have when I print out the information e.g. dith m� I get dith m,.When I query the table the information comes out correct its only when the data is retrieved do I have problem..If any would could help it would be great.

Try changing your output stream format from UTF8 to UTF16. It sounds like an encoding problem to me.

Thanks for the reply how would i introduce utf 8 encoding.
The part of the code that retrieves and outputs the data is below.

try 
{
      Class.forName( JDBC_DRIVER ); // load database driver class
      // specify properties of JdbcRowSet
      JdbcRowSet rowSet = new JdbcRowSetImpl();  
      rowSet.setUrl( DATABASE_URL ); // set database URL
 
      rowSet.setCommand("SELECT positive FROM verbTable4 " +
    "WHERE word = '" + verbList.getSelectedItem(). 
                        toString()+ "'" ); // set query
      rowSet.execute(); // execute query
      
      // process query results
      ResultSetMetaData metaData = rowSet.getMetaData();
      int numberOfColumns = metaData.getColumnCount();
       
       // display each row
       while ( rowSet.next() ) 
       {
           for ( int i = 1; i <= numberOfColumns; i++ )
   {
              area.append( "\n"+ rowSet.getString( i ) + "\t");
   }
   System.out.println();
        } // end while
} // end try
catch ( SQLException sqlException ) 
{
       sqlException.printStackTrace();
       System.exit( 1 );
} // end catch
catch ( ClassNotFoundException classNotFound ) 
{
     classNotFound.printStackTrace();            
     System.exit( 1 );
} // end catch                                 
} // end constructor

I think he meant change the charset for your response output stream: http://72.5.124.55/javaee/5/docs/api/javax/servlet/ServletResponse.html#setCharacterEncoding(java.lang.String)

You could also use setContentType() with the charset, as mentioned in the docs ( same link as above )

Moving to our servlet forum since this is about content types.

I do not see the original poster saying anything about servlet .
Nor this question is related to servlets.

Have a look at the encoding the database is currently on. Try to write with that encoding. Can you please provide some information on what technology you are using. For example Servlet -> JDBC -> DB and servlet redirects to JSP

[Paul Cullen]

I am using Eclipse.My program is a stand alone java swing front end using a MySQL database.I have set the encoding in MySQLI have queried the database with a statement from the MySQL server.This produces the correct output. But when I send it to the front end to display fron the database. It prints out "bheadh s," instead of "bheadh s�".
Here is the part of the code that retrieves an d prints it out.
public void verbSearch()
{
// connect to database books and query database
try
{
Class.forName( JDBC_DRIVER ); // load database driver class

// specify properties of JdbcRowSet
JdbcRowSet rowSet = new JdbcRowSetImpl();
rowSet.setUrl( DATABASE_URL ); // set database URL

rowSet.setCommand( "SELECT positive FROM verbTable4 " +
"WHERE word = '" + verbList.getSelectedItem().toString()+ "'" ); // set query
rowSet.execute(); // execute query

// process query results
ResultSetMetaData metaData = rowSet.getMetaData();
int numberOfColumns = metaData.getColumnCount();
//System.out.println( "Authors Table of Books Database:" );

// display each row
while ( rowSet.next() )
{
for ( int i = 1; i <= numberOfColumns; i++ )
{


area.append( "\n"+ rowSet.getString( i ) + "\t");
}
System.out.println();
} // end while
} // end try
catch ( SQLException sqlException )
{
sqlException.printStackTrace();
System.exit( 1 );
} // end catch
catch ( ClassNotFoundException classNotFound )
{
classNotFound.printStackTrace();
System.exit( 1 );
} // end catch
} // end constructor

Try changing character encoding for eclipse workspace.

Goto windows>preferences>general>workspace.
change the text encoding to UTF-16 from default.

Thanks for the reply.I tried this and got my code put in japenese.
