Java.lang.IllegalStateException:Already Connected

HI everyine,
I trying to send some data from an applet to a servlet: Here is code for the applet:try{
     System.out.println("in the try for getData \n");
     URL url = new URL("http://myip/app/servlet/getData");
     System.out.println("the url connection to getData done \n");
    URLConnection servletConnection2 =url.openConnection();
    ///////////////I get error java.lang.IllegalStateException:Already Connected at this point //////
    servletConnection2.setDoInput(false);
    servletConnection2.setDoOutput(true);
   servletConnection2.setUseCaches (false);
   servletConnection2.setDefaultUseCaches (false);
   servletConnection2.connect();
servletConnection2.setRequestProperty("Content-Type","application/octet-stream");
ObjectOutputStream oos = new ObjectOutputStream(servletConnection2.getOutputStream());
     oos.writeObject(userID);
     oos.flush();
     System.out.println("the userID was flushed");
     oos.close();
catch(Exception e)
     System.out.println("Error in sending data to getData Servlet \n" +e);
}Here is what I have in my servlet:
public class getData extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
     throws ServletException, IOException {
                        String username ="";
     try
   ObjectInputStream in = new ObjectInputStream(request.getInputStream());
     username = (String)in.readObject();
     System.out.println("the username received from ui is \n" +username);
     in.close();
catch (IOException e)
System.out.println("error1" + e);
catch (ClassNotFoundException cnfe)
{                                        {System.out.println("error2");
public void doPost(HttpServletRequest request, HttpServletResponse response)
     throws ServletException, IOException {
                     doGet(request,response);
}When I try to access this applet I keep getting an error :
java.lang.IllegalStateException: Already connected
I cannot understand why this could eb happening ..I have been stuck on this problem for quite some time now.....
Thanks,
G.

i have try your code and it fails also.
but when i add the servletConnection.getInputStream() in the applet it is ok (although i didn't write the doGet() in the servlet to reply it , but it seems that, in your orginal code, the applet didn't connect to the servlet actually)
the following is my applet and servlet code which is successful.
public class ui4 extends JApplet
public void init()
String userID="gaurj";
String servletStr ="http://192.168.0.154:8080/wmshitClient/test";
try
URL getDataservlet = new URL( servletStr );
URLConnection servletConnection = getDataservlet.openConnection();
System.out.println("the opencon was successful");
     servletConnection.setDoInput(true);
     servletConnection.setDoOutput(true);
     servletConnection.setUseCaches (false);
     servletConnection.setDefaultUseCaches (false);
servletConnection.connect();
     ObjectOutputStream outputToServlet = new ObjectOutputStream(servletConnection.getOutputStream());
     outputToServlet.writeObject(userID);
     System.out.println("object written");
     outputToServlet.flush();
     System.out.println("the userID was flushed");
     outputToServlet.close();
// i don't know why, but add the following code make it success
     String message="";
     InputStreamReader reader=new InputStreamReader( servletConnection.getInputStream());
     BufferedReader in=new BufferedReader(reader);
     message=in.readLine();
     while(message!=null){
          if(message!=null)
               message=in.readLine();
catch(Exception e)
     System.out.println("Error in sending data to getData Servlet \n" +e);
public class test extends HttpServlet {
String userID=null;
public void init(ServletConfig config) throws ServletException {
     super.init(config);
     System.out.println("in the test!!!");
public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
     System.out.println("the");
     ObjectInputStream inputFromApplet = null;
     try
     // get an input stream from the applet
     inputFromApplet = new ObjectInputStream(request.getInputStream());
userID = (String)inputFromApplet.readObject();
System.out.println("the userID receved from applet is " +userID);
          inputFromApplet.close();          }
     catch(Exception e)

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?

Got java.lang.IllegalStateException: IOException: "utf-8"

Can someone please help me with this? I got a java.lang.IllegalStateException: IOException: "utf-8" error when calling web service. The exception is like the following:
javax.xml.ws.soap.SOAPFaultException: java.lang.IllegalStateException: IOException: "utf-8"
at com.sun.xml.ws.fault.SOAP11Fault.getProtocolException(SOAP11Fault.java:196)
at com.sun.xml.ws.fault.SOAPFaultBuilder.createException(SOAPFaultBuilder.java:122)
at com.sun.xml.ws.client.dispatch.DispatchImpl.doInvoke(DispatchImpl.java:196)
at com.sun.xml.ws.client.dispatch.DispatchImpl.invoke(DispatchImpl.java:215)
at oracle.sysman.connector.common.ConnectorServiceSoapWrapper.sendRequestBase(ConnectorServiceSoapWrapper.java:202)
ConnectorServiceSoapWrapper is my class and in sendRequestBase() method I had the following statement to invoke the web service.
Dispatch<SOAPMessage> dispatch = service.createDispatch(null, SOAPMessage.class, Service.Mode.MESSAGE);
SOAPMessage responseMsg = dispatch.invoke(msg);
dispatch object is an instance of javax.xml.ws.Dispatch and service is an instance of javax.xml.ws.Service. It looks like the error is thrown out before the web service is called. Does anyone have any idea what's happening here?
My java version is
java version "1.6.0_14"
Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Java HotSpot(TM) Server VM (build 14.0-b16, mixed mode)
Thanks!

I was reading the source code of com.sun.xml.ws.client.dispatch.DispatchImpl
http://www.docjar.com/html/api/com/sun/xml/ws/client/dispatch/DispatchImpl.java.html
And the following piece of the code is part of the stack trace.
+195 } catch(Throwable e){+
+196 // it could be a RuntimeException resulting due to some internal bug or+
+197 // its some other exception resulting from user error, wrap it in+
+198 // WebServiceException+
+199 throw new WebServiceException(e);+
+200 }+
Anyone has any hint? Thanks!

Database control shows java.lang.Exception: IOException in connect refuse

Hi All,
I need some help on this issue.
I followed MOS Doc 259387.1 to reset dbsnmp password because its password is unknown.
The error is
Error

Thanks in advance.

Hi,
Posting this error in metalink you could get nice directions...
I have the same problem, and looks fixed now...
Try review doc 420761.1
And what I do, was:
Stop dbconsole
start dbconsole (fails)
review logs generated and look this errors:
$ORACLE_HOME/<hostname>_<instance_name>/sysman/log
doing there a directory listing by date, "ls -ltr" the last file showed is the modified one, in my case was:

-rw-r----- 1 oracle oinstall 522694 Oct 27 19:34 emdb.nohup

And tail emdb.nohup gives you the instructions to fix the first one, in my case, solving the TZRegion was enough.
$ tail emdb.nohup
----- Tue Oct 27 19:19:05 2009::The agentTZRegion value in /oracle/product/102/db_1/dbserver.uadec.mx_siin/sysman/config/emd.properties is not in agreement with what agent thinks it should be.Please verify your environment to make sure that TZ setting has not changed since the last start of the agent.
If you modified the timezone setting in the environment, please stop the agent and exectute 'emctl resetTZ agent' and also execute the script 'mgmt_target.set_agent_tzrgn' to get the value propagated to repository -----
Hope this could help you.

Any idea ?????

Hi,
Please post the exact release of R12 along with the database version and OS.
Is this issue with specific notification? If yes, please mention the steps to reproduce the issue.
Was this working before? If yes, any changes have been done recently?
Can you find any errors in the Workflow log file?
Thanks,

Java.io.IOException: Connection reset by peer

Hi,
I'm writing a web app that has to encode jpeg to return pictures in servlet response. It seems to work fine under tomcat web server, but it crashes under iplanet when a client posts a lot of requests in a very short time : when I try to write in the ServletOutputStream, I get the following exception, and then it seems that my iplanet server doesn't handle such a case ? Any idea ?
Thanks in advance,
Sebastien

More details :
I try to increase load by submitting lot of requests (from a single client), causing many of these requests to be aborted (I assume), so when I try to prepare the response (server side), I catch a IOException : connection reset by peer. Simultaneously, I can see in Iplanet's error logs the following snippet :

Please help.
Thanks

It just displays the login UI components and a link at top-left displays "Skip to Content". When the username and password is entered and hit the submit button, it doesn't work. This issue is intermittent.
Please help as this is a show stopper to my deliverables.

Getting java.lang.IllegalStateException error with response.getOutputStream

Hi,
I am writer a JSP site for displaying JFreeChart. The main JSP page gets some parameters then the second page out put the chart as binary data with a Java class.
I've located the part which generated the error, as follows:
Code:
OutputStream os = response.getOutputStream(); <--- this line cause the error
response.setContentType("image/png");
ChartUtilities.writeChartAsPNG(os, chart, 400, 300);
(other than it, the JSP does nothing with response or out)

I've searched this forum and google and seeking for solution for thousands times. But sadly, ways such as adding out.reset(); doesn't work.
Would any one has some suggestion for me? Your help is very appreciated. Thanks!

Answer
Don't know if this will help--your code worked as is on my system (J2SDK 1.4.1, Tomcat 4.1.12, Linux)--but you're setting the content-type twice, and to two different values. In the page directive, you specify contentType="text/html; charset=8859_1", and then in the scriptlet, you do a response.setContentType ("application/excel");. Try changing the one in the page directive and deleting the one in the scriptlet. The servlet container may be calling getOutputStream() when it sees the text MIME type so it can prepare the out built-in variable.
Also, according to the J2EE design patterns, JSP's should only be used to produce text output. Any binary output (such as Excel files) should be produced with servlets--otherwise, the JSP becomes one big scriptlet (like this one).
If you still want to do this with a JSP, you might want to take out your try ... catch block since you're not doing anything with it. Doing so will allow you to let the servlet container handle the errors (i.e. specify error pages in the web application deployment descriptor). Either that, or at least put the close() and flush()calls in it since they can throw IOExceptions, too. :)
Finally, you should never close the servlet's output stream. Leave that up to the servlet container.

%> // make sure that's no breakline an no spaces at the end!!
Re: Breakline problems
Aarthi Sivaram, Apr 19, 2005
In the above code sosStream = response.getOutputStream(); must be removed. Use 'out' instead of sosStream i.e. out.write(""+ibit); If you look at the Java code generated for your JSP, you can find JspWriter out = null ... .. JspWriter calls response.getOutputStream(), thats why when u call getOutputStream, u get IllegalStateException. 'out' variable is available for direct use in all JSP's, like 'request'. So that can be directly used to write.
A quick and working workaround
Leslie Leng, May 20, 2005 [replies:1]
I am not going to discuss the theory behind, as others gurus mentioned before me, are valid.
In short, getOutputStream() could not be used more than once, and also it will conflict with JSPWriter's out.
So, the quick workaround would be, at the end of the JSP page, add the following:
out.clear();
out = pageContext.pushBody();
in example:
catch(Exception e){
System.out.print(e);
out.clear();
out = pageContext.pushBody();
%>

ZIP file download throws java.lang.IllegalStateException: Response already

Hello.
In my application I need to implement a functionality where user will able to download multiple image files of their choice in compressed zip format. To implement it I used af:fileDownloadActionListener. I need to submit the form before going to process the zip. For that I have added to af:commandLinks.
The following commandlink will process the download:
<af:commandLink id="cl19" binding="#{pageFlowScope.album.downloadZipLink}" visible="false" text="jym">
                <af:fileDownloadActionListener filename="Compressed.zip" contentType="application/zip" method="#{pageFlowScope.album.downloadZip}"/>
</af:commandLink>And this commandlink will submit the form and invoke the click event of the first commandlink
<af:commandLink text="Download" styleClass="functionButton" id="cl13" actionListener="#{pageFlowScope.album.downloadZip}"/>The downloadZip actionlistener is:
    public void downloadZip(ActionEvent actionEvent) {
        FacesContext context = FacesContext.getCurrentInstance();
        ExtendedRenderKitService service = Service.getService(context.getRenderKit(), ExtendedRenderKitService.class);
        StringBuilder builder = new StringBuilder();
        builder.append("var link = AdfPage.PAGE.findComponentByAbsoluteId('").append(downloadZipLink.getClientId(context)).append("');");
        builder.append("AdfActionEvent.queue(link, false);");
        service.addScript(context, builder.toString());
    }And the downloadZip af:fileDownloadActionListener's method is:
    public void downloadZip(FacesContext facesContext, OutputStream outputStream) throws IdcClientException, IOException {
        ZipOutputStream zipOutputStream = new ZipOutputStream(outputStream);
        for(List<Image> images : getAlbumDetailCurrent()){
            for(Image image : images){
                if(image.isChecked()) {
                    CloseNotifyInputStream inputStream = (CloseNotifyInputStream)ridcConnection.getFileInputStream(image.getDocId(), image.getDocName());
                    String filename = getImageFilename(image.getDocName(), image.getFormat());
                    zipOutputStream.putNextEntry(new ZipEntry(filename));
                    IOUtils.copy(inputStream, zipOutputStream);
                    inputStream.close();
                    zipOutputStream.closeEntry();
        zipOutputStream.close();
    }Everything is working fine. The zip is creating and and is being thrown to the user, but in console I am getting the following exception:

     Truncated. see log file for complete stacktraceI am unable to find its cause. It is not causing any problem in webpage.
Any information will be very helpful to me.
I am using JDeveloper 11.1.1.6.0.
Regards.

          The reason for this exception is when you are trying to write something on the
          response stream
          which was already closed (commit) . This may happen when u write something in
          the response stream after doing a redirect/forward. OR if u r trying to redirect/forward
          more than once. bcs once u redirect/forward your response object will be flushed
          and commited..
          Hope this may help u
          regards

Forward Request giving java.lang.IllegalStateException

Hi Friends,
I am using RequestDispatcher to forwrd my request from one servlet to another
Here's the code
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
public class TryServlet extends HttpServlet
public void service(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url="jdbc:odbc:con";
Connection con= DriverManager.getConnection(url,"scott","tiger");
Statement stmt=con.createStatement();
ResultSet rst=stmt.executeQuery("select * from Projects");
response.setContentType("text/html");
PrintWriter out=response.getWriter();
while (rst.next())
String firstname=rst.getString("PIN");
String lastname=rst.getString("ProjectTitle");
out.println("<p> Name:"+firstname+" "+lastname+"");
con.close();
RequestDispatcher rd=getServletContext().getNamedDispatcher("HelloServlet");
rd.forward(request,response);
return;
catch(Exception e)
e.printStackTrace();
I m getting the error
java.lang.IllegalStateException: Cannot forward after response has been committed
i need to include the two rows of tables before i forwad the request to HelloServlet
What needs to be done?
thanx
Pooja

Don't spread the generation of output over several servlets. Your first servlet should retrieve the data and your second servlet should display the data.
Store the data retrieved as a request attribute before forwarding:
// Data.java
public class Data {
public String _firstname;
public String _lastname;
public data(String firstname, String lastname) {
    _firstname = firstname;
    _lastname = lastname;
    return;
// TryServlet.java
public class TryServlet extends HttpServlet
List list = new ArrayList();
while (rst.next()) { // store data in list
    String firstname=rst.getString("PIN");
    String lastname=rst.getString("ProjectTitle");
    Data data = new data(firstname, lastname);
    list.add(data);
con.close();
request.setAttribute("list", list); // store list in request
RequestDispatcher rd=getServletContext().getNamedDispatcher("HelloServlet");
rd.forward(request,response); // list is forwarded as well
return;
}In HelloServlet, you get the request's attribute and display the data:
List list = (List)request.getAttribute("list"); // retrieve list from request
Iterator it = list.iterator();
while (it.hasNext()) { // retrieve data from list and display
    Data data = (Data)it.next();
    out.println("<p>Name: " + data._firstname + " " + data._lastname + "</p>");
}Btw, for displaying the data, a JSP will do better.
