my problem concerning JdbcOdbcDriver was not solved.a friend(Randy it was u!)
suggested that this driver is not thread safe/has problems with multithreading.(that's
hebrew to me,coz i am a first time server programmer)
incidentally i got the following server window msgs when using jdbcodbcdriver.can any
1 tell me what it means!!(my index page has 3 frames having first.html,second.html &
third.html.the login textboxes are in third.html which lead to login.jsp on submit.my
app is named project)
[
2001-07-06 12:50:26 - Ctx( /project ): IOException in: R( /project + /jsp/first.
html + null) Connection reset by peer: socket write error
2001-07-06 12:50:26 - Ctx( /project ): 404 R( /project + /jsp/login.js + null) n
ull
2001-07-06 12:50:26 - Ctx( /project ): IOException in: R( /project + /jsp/third.
html + null) Connection reset by peer: socket write error
]
however i also tried with a type 4 driver:i-net Seropto(tm) optional package
driver(ver1.0 for Oracle 8.0 server).classname--com.inet.ora.OraDriver.it is said to
support the following:
Oracle Server, Java and JDBC Versions
--------------------------------------
Java Versions: 1.2.x or higher
JDBC Version: 2.0
Oracle Server Version: 8.0.4.0
i have Oracle8.0.4 personal edition,jdk1.2.2.i have included the jar files for both
the driver and jdbc2.0 optional package in c:\tomcat\lib\.
i modified th login.jsp used for jdbc-odbc driver as follows:
[
<%@ page session="true" import="java.sql.*,java.io.*" %>
<%
String s1=request.getParameter("user");//username
String s2=request.getParameter("pwd");//password
String upwd=null;
FileOutputStream fos=null;
PrintStream prs=null;
try{
fos=new FileOutputStream("error.txt");
prs=new PrintStream(fos);
//DriverManager.setLogStream( System.out );
if(s1.length()==8 && s2.length()==6)
{
out.println("loading driver");
Class.forName("com.inet.ora.OraDriver").newInstance();
out.println(" driver loaded");
DriverManager.registerDriver(new com.inet.ora.OraDriver());
out.println("driver registered");
Connection
con=DriverManager.getConnection("jdbc:inetora","scott","tiger");
out.println("got connection");
Statement ps=con.createStatement();
// ps.setString(1,s1);
ResultSet rs=ps.executeQuery("SELECT password FROM login WHERE
username'"+s1+"'");
if(rs!=null)
{
while(rs.next())
{
upwd=rs.getString("password");
}
}
con.close();
if(upwd!=null)
{
if(s2.equals(upwd))
{
out.println("Welcome Back to this site
"+s1);
}
else
{
out.println("Incorrect password");
}
}
else
{
out.println("Incorrect username ");
}
}
else
{
out.println("Invalid no. of characters in username/password");
}
}
catch(Exception ex){
ex.printStackTrace(prs);
out.println(ex.getMessage());
out.println(ex);}
%>
]
i got the following output in the browser:
loading driver driver loaded driver registered Connection refused: no further
information com.inet.ora.SQLException: Connection refused: no further information
what the hell??
please offer a solution.
thanx.
