Ok.
Why do you use youre own PrintWriter?
You have a stream from HttpServlet Object. Use this.
Use something like this:
* Test.java
* Created on 18. Februar 2003, 10:13
import java.io.*;
import java.net.*;
import javax.servlet.*;
import javax.servlet.http.*;
* @author Mueller
* @version
public class Test extends HttpServlet {
    /** Initializes the servlet.
    public void init(ServletConfig config) throws ServletException {
        super.init(config);
    /** Destroys the servlet.
    public void destroy() {
    /** Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
     * @param request servlet request
     * @param response servlet response
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        /* output your page here */
        out.println("<html>");
        out.println("<head>");
        out.println("<title>Servlet</title>");
        out.println("</head>");
        out.println("<body>");
        out.println("My first servlet");
        out.println("</body>");
        out.println("</html>");
        out.close();
    /** Returns a short description of the servlet.
    public String getServletInfo() {

Io exception: Connection reset by peer: JVM_recv in socket input stream read

We are developing a new J2EE app using JDev, OC4J, servlets, and EJBs. We have determined that our firewall is closing database connections that have been idle for 1 hour. This is a security requirement that cannot be changed. When we try to use these idle connections in both stateless and entity beans, we consistently receive this or a similar error message:
"ServletSACategoryList: Error invoking EJB procedure. Exception: java.sql.SQLException: StatelessSysAdminBean::getCategoryList - Io exception: Connection reset by peer: JVM_recv in socket input stream read "
Environment:
Oracle 9iAS 9.0.2.0.0
Database: Oracle 8.1.7
JDBC 8.1.7
JDK 1.3
JDev 9.0.2.829
We are using the ejb-location attribute within data-sources.xml for JNDI lookup of the DataSource. Here is what this file looks like:
<data-sources>
<data-source
class="oracle.jdbc.pool.OracleDataSource"
name="jdbc/OracleDS"

</data-sources>
After calling getConnection() on the Connection object in my stateless bean, I have tried checking if the Connection object is null or isClosed(), I have caught any Exception, and looped to try again, but nothing has worked.
Please respond to [email protected] or directly to this post if you can help in any way.
Thank you,

Hi Robert,
If you don't mind, I can only offer a few suggestions for things
to try -- I'm afraid I don't have a solution for you. Of-course,
you may have already tried these things, so please excuse me if
this is the case.
Firstly, your "data-sources.xml" file looks "different". Have
you read the "Data Sources" chapter of the "Oracle9iAS Containers
for J2EE Services Guide, Release 2 (9.0.2)"? It is accessible
from here:
http://otn.oracle.com/docs/products/ias/doc_library/90200doc_otn/web.902/a95879/ds.htm#1004903
Also, have you tried running OC4J in "debug" mode? This web
page has more details:
http://kb.atlassian.com/content/atlassian/howto/orionproperties.jsp
I get the impression from the information you have supplied,
that you may not be explicitly closing your database connections
in your code. It looks to me like you are obtaining a database
connection in your session bean, and then keeping it for the
lifetime of that bean. Is that correct? I think it's better
to obtain a connection when you need to interact with the database,
and then close the connection immediately after completing the
interaction with the database (but that's just my opinion).
Lastly, if you haven't already discovered them, these web sites
may also be of help:
http://www.orionserver.com
http://www.orionsupport.com
http://www.elephantwalker.com
Hope this helps you.
Good Luck,
Avi.

Io exception: Connection timed out during Active Sync

I received this connection exception during an Active Sync Process.
The exception caused the process to halt for 9 minutes - it then picked again and continued processing accounts.
We are running IdM v5.0 SP6, Tomcat Application Server, and an Oracle 9 Repository.
Any ideas?

Hi,
It seems the query is taking too long and eventually the connection to the database is timing out.
I also believe that you are on the supported database configurations for WLS 10.0 MP1 :-
Link:[http://edocs.bea.com/platform/suppconfigs/configs100/100_over/supported_db.html]
You will also have to look in the weblogic server log for relevant errors like socket exceptions.

Flood of "TLS connection exception: handshake incomplete"

Good day every body!
I am using 4215 IPS-K9-6.0-4a-E1 image. Recently our sensor started to generate a lot of errors like that (when connected by IDM):
evError: eventId=1208572151825393108 severity=error vendor=Cisco
originator:
hostId: sens-1
appName: cidwebserver
appInstanceId: 384
time: 2008/06/03 16:00:26 2008/06/03 16:00:26 UTC
errorMessage: name=errTransport WebSession::sessionTask TLS connection exception: handshake incomplete.
I do understand that there is something wrong with tls certificates. So here are the things that I've tried:
-Regenerate HTTPS certificate and reconnect. Nope, doesn't work.
-Reset sensor to defaults, set IP anew, regenerate certificates. Nope, doesn't work.
-I've also searched this forum, found some topics having the same problem... But there weren't any solution stated.
I do not want to use simple HTTP, so this is not an option.
Could this be a client problem? My client host is MS Windows Server 2003, Sun JRE 1.5, IE 6.
I'd be very thankful if anyone could point me a solution to this issue!
Thanks in advance!
Andrew

That message is common when something is connecting to the sensor through HTTPS but is using the wrong TLS certificate.
However, this message does not let you know which box is having this connection problem.
If you are able to connect in from IDM and IDM is working fine, then it is likely that it is not IDM that is causing the errors.
More than likely there is another box (or application) on your network that is trying to connect and still has the old SSL certificate of the sensor.
That Other box needs to be updated with the sensor's newest SSL certificate.
To figure out the IP address of the Other box you could try and use the "packet display" command on the sensor's command and control IP Address to look for HTTPS sessions to the sensor that are short lived.
My best guess is that you may have an old installation of IEV or some other monitoring tool that is trying to connect to the sensor using an old SSL certificate, and that application needs to be updated to use the sensor's newest SSL certificate.
If you can't connect in from IDM, and during those attempts you keep getting that error. Then your web browser has the old certificate cached, and you need to get your browser to accept the newest SSL certificate from your sensor. IDM should then start working and the error would go away.

Java.lang.IllegalStateException: Already Connected Exception

I get java.lang.IllegalStateException: Already Connected Exception while executing
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
(Exception here) conn.setDoOutput(true); // we want to send things
// the Content-type should be default, but we set it anyway
conn.setRequestProperty( "Content-type", "application/x-www-form-urlencoded" );
// the content-length should not be necessary, but we're cautious
conn.setRequestProperty( "Content-length", Integer.toString(body.length()));
Can any one please let me know how to get this thing fixed

Remove either the line setRequestMethod("POST") or the setDoOutput(true). How did you came on the idea to set them both?

Java connection exception

I am trying to connect to an external server from a proxy , but I get a java.connection exception : remote host did not respond within the time
out period ..
how do i solve this issue ? can i explicitly set an increased time out on the connection ?

I am trying to use sockets to address the issue of time outs..the code i have is as follows..i am trying to post an xml file , i dont seem to be getting a response nor am i erroring out ?
String host = "http://mysite.activation.com";
Socket sckt = new Socket(host,80);
     sckt.setSoTimeout(10000);
     String method = "POST";
String messageString = "<?xml version='1.0' encoding='UTF-8' ?>" +
     "<Test.Users>" +
     "<User userID='"+test+"' />"+
     "</Test.Users>" ;
     OutputStream out = sckt.getOutputStream();
     out.write(method.getBytes());
     out.write(messageString.getBytes());
     out.flush();
     out.close();

Java.sql.SQLException: E/A-Exception: Connection ended abnormally

Hi all,
this strange exception occurs in the communication channel monitoring. I see there was a processing error in the communication channel which inserts data from XI. When I look in audit protocol I can see that after a few minutes the connection is ended with an error which says the following:
Error processing request in sax parser: Error when executing statement for table/stored proc. 'LVS' (structure 'STATEMENTNAME'): java.sql.SQLException: E/A-Exception: Connection ended abnormally.
Now my questions are: Why does this error occur? And can someone explain me this error?
Regards
Florian

I think I have the reason for this problem. It's a network problem. The network to this system has a high load. In addition, the JDBC receiver adapter was configured with parameter <i>"Disconnect from Database After Processing Each Message".</i> Now I have deselected the parameter and I have no problems.
Thanks for your efforts
Florian

I'd guess it's a database problem. Probably something to do with the way you open and close database connections, or the nature of the link to the Oracle server. It might even be an authentification problem.
The problem is that there's a third trace block not being displayed here. The servlet exception probably also has a "root cause" exception which is not being printed on the trace. You may find more information in Tomcat's log files, but then again you may not.
You may want to think about putting an explicit try - catch block in the offending jsp as a debugging aid and, thus, catching and displaying the expception in an "unwrapped" state.

Io exception: Connection reset

Dear,
my scenario is: SAP MII accesses an Oracle database and reads messages form this database to subsequently send to a webservice.
For some messages, with size of 4K, the MII can complete the process successfully.
For other messages that have size of 89K, the error occurs:
: com.sap.xmii.Illuminator.logging.LHException: com.sap.xmii.Illuminator.logging.LHException: com.sap.xmii.Illuminator.logging.LHException: Error occurred while processing records; Io exception: Io exception: Connection reset
How can I solve this problem?
Best Regards,
Sérgio Salomã

You need to determine where the issue is occuring. How are you calling the transaction? Do you have proper error handling under the sql and web service actions?

Here is the Java code if it helps.
FaxPage faxPage;
byte[] image;
StringBuilder sqlString = new StringBuilder();
sqlString.append("INSERT INTO faxviewer.fax_page ( ");
sqlString.append("fax_page_id, "); // 1
sqlString.append("fax_id, "); // 2
sqlString.append("fax_page_number, "); // 3
sqlString.append("fax_image ) "); //4
sqlString.append("VALUES ( ");
sqlString.append("?, ?, ?, ? ) ");
stmt = conn.prepareStatement(sqlString.toString());
stmt.setInt(1, faxPage.getFaxPageId());
stmt.setInt(2, faxPage.getFaxId());
stmt.setInt(3, faxPage.getFaxPageNum());
stmt.setBytes(4, image);
int rowcount = stmt.executeUpdate(); // Exception 17002 sometimes here

Connection refused: connect exception

Dear All,
while connecting to localhost using the below program, i am getting Connection Refuded: connect exception.
import java.io.*;
import java.net.*;
import java.util.*;
public class SocketTest {
private java.net.ServerSocket serverSocket;
public static void main(String[] str) {
int port = 12034;
InetAddress dst = null;
try {
dst = InetAddress.getByName("localhost");
} catch (UnknownHostException e) {
e.printStackTrace();
System.out.println("chrono"+dst.getCanonicalHostName());
System.out.println("chrono"+dst.getHostName());
Socket sock;
try {
sock = new Socket(dst, port);
System.out.println("aftersocket");
} catch (IOException e) {

Regards,

Do you have a server on your localhost awaiting connections on port 12034?

Io exception: Connection refused Error

I am trying to configure a connection pool on Weblogic 8.1 using Oracle thin client.
When I click on the Test Driver configuration, I get the following error:
Io exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=153092352)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))
I have verified that the username/url are correct.
Any ideas?

I am not sure how to run utils.dbping.Try this:
C:\> java utils.dbping
It will print out a usage message.
Anyway, I am able to connect to the database using SQLPlus. I have the following
entry in my tnsnames ora:
dbalias.world=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = server.xx.com)(PORT = 1521))
(CONNECT_DATA =
(service_name = dbname)
)Ok, and how did you define the pool? What were the properties and URL?
Did your URL contain 'dbname' as the SID, or did you set the SID in the properties?
show me the pool definition and show me how you start SQL-PLUS.
Joe
Thanks!

Help!!getting Connection Exception &permission denied for my local system

Hi,
I am getting this connect Exception when i am running my RMI program.It is not comming when i am running all the programs[server,client] in my local system.
When i put the server program in the server which is linux server and i am calling it from my local system its giving ConnectException permission denied to 127.0.0.1,no more further infoemation.
These are the programs..
server :
import java.net.*;
import java.rmi.*;
public class AddServer
public static void main(String args[])
     try
     AddServerImpl addServerImpl=new AddServerImpl();
     Naming.rebind("AddServer",addServerImpl);
     catch(Exception e)
     System.out.println("Exception :"+e);
Implement:
import java.rmi.*;
import java.rmi.server.*;
public class AddServerImpl extends UnicastRemoteObject
implements AddServerIntf
public AddServerImpl()throws RemoteException
public double add(double d1,double d2)throws RemoteException
     return d1+d2;
Interface:
import java.rmi.*;
public interface AddServerIntf extends Remote
     double add(double d1,double d2)throws RemoteException;
Client Program :
import java.rmi.*;
import java.rmi.registry.*;
public class AddClient
     public static void main(String args[])
     try
//     String addServerURL="rmi://"+args[0]+"/AddServer";
     Registry r=LocateRegistry.getRegistry("rmi://"+args[0]);
//AddServerIntf addServerIntf=(AddServerIntf)Naming.lookup(addServerURL);
AddServerIntf addServerIntf=(AddServerIntf)r.lookup("AddServer");
System.out.println("The firsrt number is"+args[1]);
double d1 =Double.valueOf(args[1]).doubleValue();
System.out.println("The second number is:"+args[2]);
double d2=Double.valueOf(args[2]).doubleValue();
System.out.println("The sum is:"+addServerIntf.add(d1,d2));
catch(Exception e){
     System.out.println("Exception:"+e);
Plese go thru it and tell what modifications that i have to do with it...
regards,
j.mouli

You can specify a policy file and grant the following pemission in it:
grant {
permission java.net.SocketPermission "*:1024-65535","accept, connect, listen, resolve";
Specify this policy file using "-Djava.security.policy=your policy file".
BTW, don't forget to run rmiregistry before you launch your own RMI application.
Good luck!
