.

try { 
    stmt = connection.createStatement(); 
    rset =   stmt.executeQuery(url) ;  
}  catch (Exception e) 

{  
    error= e.getLocalizedMessage() ;
    return 4; 
}

this error occurs because of { } parentheses. I test it .
When I delete parentheses dont error. But I need them and How can I fix this?

It’s all about { and }. You do not use them. Ojdbc won’t parse it. Use different token instead of them.
