HttpsUrlConnection - Facing problem while reading the input stream and establishing the cookie

Please find below the error that I am getting while reading the input stream.

The value of cookie in the process request is ............... null
java.io.EOFException

Please help me.
Thanks in advance.

Hi,

Can you please make your question more descriptive.....

we didn't get more idea what is your problem ??

Please also put some code what you use ?

I tried by including the following to establish the cookie

<sun-web-app>
<session-config>
<session-manager persistence-type="memory">
<manager-properties>
<property name="reapIntervalSeconds" value="20" />
</manager-properties>
</session-manager>
<session-properties>
<property name="enableCookies" value="true" />
</session-properties>
<cookie-properties>
<property name="cookiePath" value="/" />
<property name="cookieMaxAgeSeconds" value="-1" />
</cookie-properties>
</session-config>
<jsp-config/>
</sun-web-app>

in the sun-web.xml.

Please find the code that I am using.

Please http://faq.javaranch.com/java/UseCodeTags. You can edit your post to add them.

And please, don't use blue as your text color. Black is much easier to read.

Please provide me an approach to resolve this issue.
Thanks in advance.

I still can't read your code properly. Where are those code tags?

I tried by including the following to establish the cookie

Please find below the code that I am using to establish the cookie.
And you can see in the log the cookie is not getting established.

Please advice me on how to establish the cookie?
Thanks in advance.

The exception is thrown from the ObjectInputStream's constructor, which indicates that the required meta-data bytes are missing. Apparently the other side of the connection does not use an ObjectOutputStream for writing when you receive this exception. Are you sure that this connection is coming from your application, and not something else?

Please find below the code that I am using to write as well as read the InputStream.

private boolean sendRequest(PageWrapper pWrapper) {    
	ObjectOutputStream out = null;    
	try {    
		connection.setDoInput(true);    
		connection.setDoOutput(true);    
		System.out.println("Inside sendRequest");    
		out = new ObjectOutputStream(connection.getOutputStream());    
		out.writeObject(pWrapper);    
		out.flush();    
	} catch (Exception e) {    
		e.printStackTrace();    
		return false; //return false in case of Exception    
	} finally {    
		try {    
			if(out != null)    
			out.close();    
		} catch(Exception e) {    
			Console.println("Unable to close Connection"+e);    
		}

}    
	return true;    
}    
  
  
private PageWrapper receiveRequest() {    
  
	PageWrapper pWrapper = null;    
	ObjectInputStream in = null;    
	try {    
		System.out.println("Inside receiveRequest");    
		in = new ObjectInputStream(connection.getInputStream());    
		System.out.println("The Object Input Stream is .............." + in);    
		pWrapper = (PageWrapper)in.readObject();    
		System.out.println("The page wrapper Object is .............." + pWrapper);    
	} catch(Exception e) {    
		e.printStackTrace();    
		pWrapper = new PageWrapper();    
		pWrapper.setStatus(false);    
		pWrapper.setErrorMessage(FISConstants.ERROR_URL);    
	} finally {    
		try {    
			if(in != null)    
			in.close();    
		} catch(Exception e) {    
			Console.println("Unable to close Connection");    
		}    
	return pWrapper;    
	}    
}

But are you sure that it is this piece of code that connects?

Find below the code where I am opening the connection and setting the cookie.

I hate to say it, but it seems that the simple fact is that nobody knows why it isn't working.
