Inputstream.java.io.IOException , applet connection
I'm working on a problem with the failure of a java
applet connection to a java servlet.
The connection is via the internet, and over port 80.
the java console loggin reports the following
There was an attempt to redirect a url request,
but the attempt was not allowed by the client. IOException caught in run
could some one let me know what the URL re-direction is here,
much apreciated,
slainte
I have often found this problem with inexperts java programmers.
I could tell you better luck next time, but today I feel generous, so I will answer.
There is a redirect domain problem. When you try to connect the site you receive an ICMP error message, which is the responsable of the error message you can see. That occurs because the URL connects to another URL different (surely because its original URL has changed to another) and you only have to discover the new URL, and try to connect to it.

Java.io.IOException: Persistent connection dropped
Hi all,
I am currently testing my midlet that uses a HTTP connection to link to a server using the emulator. However, I keep getting the following exception about a minute after the connection is established:
java.io.IOException: Persistent connection dropped after first chunk sent, cannot retry
at com.sun.midp.io.j2me.http.Protocol.sendRequest(+102)
at com.sun.midp.io.j2me.http.Protocol.sendRequest(+6)
at com.sun.midp.io.j2me.http.Protocol.closeOutputStream(+4 )
at com.sun.midp.io.BaseOutputStream.close(+14)
at java.io.DataOutputStream.close(+7)
at Conn.sendData(+25)
at Conn.doPost(+17)
at Conn.upload(+4)
at UploadThread.run(+7)
Here is the code for my sendData() method
public static void sendData( HttpConnection connection, String data ) throws IOException
byte[ ] dataOut = data.getBytes();
DataOutputStream os = connection.openDataOutputStream();
try
os.write( dataOut );
os.flush();
finally
os.close();
}Any help or suggestions as to why I am getting this exception would be greatly appreciated.Should i use a persistent connection and could you try to explain what the
exception actually means?I just thought that the connection may be dropped somehow (maybe a timeout) and it may be related to closing OutputStream you obtain from the connection.
Every time i send data i create a new thread that opens up a new connection
and sends the data and receives the response.
I does this as i am only sending and receiving very small amounts of data. I am thinking that there can be a better design for your application. Is it possible?
1. If you are using the same connection (i mean socket connection not output)
why do you close the OutputStream after sending each data. As far as i know flush does this already.
So why dont you close both the connection and the OutputStream when the job of your program ends.
2. If you are not using the same connection for each thread, (aagain) why dont you open and close both the connection and the OutputStream in your finally block of your thread?

The applet is in the same directory as the ASP. It is a NT 4 (SP6) server. The applets loaded and ran fine with jdk1.3. Do I need to do something different in my ASP, or IIS setup to allow java applet HTTP connection in JDK1.4?
Thanks!I have the exact same problem but have yet to find a solution.
It works fine in 1.3 but fails occasionally in 1.4. If I refresh the browser several times it eventually
loads.

Java.io.IOException: Connection failure with 500
Hi
When i am trying to establish connection from applet to servlet using URLConnection..
It is giving me java.io.ioexception Connection failure with 500.
Can anybody let me know why and how to solve this.
Thanks&Regards,
SubbaError code 500 is "Internal Server Error." Unfortunately this could be loads of things. :-(
What servlet / web-server are you using?
Some general pointers.....
- Check your web-server access log and see if the request is received. (I'd expect so as you're getting a 500 error)
- Check your servlet log & see if it is init-ing correctly.
- I always write a simple doGet() method in my servlets so that I can check whether the servlet is alive or not...
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = new PrintWriter (response.getOutputStream());
out.println("<html>");
out.println("<head><title>ObjectServlet</title></head>");
out.println("<body>doGet() called: "+new java.util.Date());
out.println("</body></html>");
out.close();
Logger.log(this, "doGet", Logger.TRACE, Logger.TRACE_OUT);
Then repost if you're still stuck. -
Java.io.IOException: Connection failure with 400
at sun.plugin.protocol.jdk12.http.HttpURLConnection.getInputStream(Unknown Source)
This occurrs when using getInputStream()
The URL can be cut and pasted into the browser and it works fine, but when the code executes and only using the plugin it gives this error.
Any ideas??One of my customers is getting :
java.io.IOException: Connection failure with 400
at sun.plugin.protocol.jdk12.http.HttpURLConnection.getInputStream(Unknown Source)
...too, on this snippet of code:
java.io.InputStream aInputStream=aURLConnection.getInputStream();
Anybody find a cause or solution for this? I believe my customer is using JRun.
Thanks in advance. -
Java.io.IOException: Connection failure with 401
Hi all,
i recently moved an applet that uses JavaHelp on a new intranet server. I got an error during applet loading since i moved all the files.
The structure of files is:
-Tarish2Applet.html
-tarish2.jar
+Tarish2Help
ooooo|---helpset.hs
ooooo|---toc.xml
ooooo|---map.xml
ooooo|---index.xml
ooooo|--+HTML
+package
I use the following HTML code to call the applet in IE6:
Tarish2Applet.html:
<!--"CONVERTED_APPLET"-->
<!-- CONVERTER VERSION 1.0 -->
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"

<PARAM NAME="type" VALUE="application/x-java-applet;version=1.2">
<COMMENT>
</OBJECT>
And i have the following output and error in the java console:
/*This first IOException seems to be due to the parameters cache_archive and cache_option in the applet call: if i remove them from the html file, this first exception disapears*/

catch (Exception ee)
System.out.println("Error during Helpset loading: "+ee);
System.out.println("HelpSet not found");
return;
Has anybody an idea about this "Connection failure with 401" that happens on .jar caching and helpset loading????
What does it come from? Is it due to the http server configuration, the java.policy file?? The code???
If you have any clue, please help me...

Java.io.IOException: Connection failure wth 407
Hi everyone,
I encountered this problem when i tried to access a system using IE at host through one of the client.
e.g. i typed 'http://1923.168.12.32:8080/whatever/web' at address field.
java.io.IOException: Connection failure with 407
at sun.plugin.protocol.jdk12.http.HttpURLConnection.getInputStream (Unknown Source)

Client PC using JRE 1.3.1_06 and IE5.
The problem is that some of the PCs can access to the system using this way but few PCs couldn't.
Any help would be highly appreciated.
Thanks alot in advance.407 is most likely to mean that authentication with a proxy server is required but that's not necessarily the case -- first thing to check though.
BTW, I'm sure it's a typo but the first octet of your address is 1923!

Still error is there. Please help me regarding this, not able to go ahead and rest in peace.
thanks & regards,
mJKHi,
have you checked proxy settings in WTK preferences?

I searched all the forums they were also talking abt proxy setting does has any idea is that is also one of the reason.

Errors: "java.io.IOException: open HTTP connection failed"
I am trying to execute an applet, but ocorrs the following errors:
"Java.lang.ClassNotFoundException: InterfaceApplet.class Caused by: java.io.IOException: open HTTP connection failed"
Why don't open HTTP connection???
I already signed the applet and my applet.html is:
codebase='http://200.134.165.36/path' code= 'applet.class' archive='appletSigned.jar'
....It's not difficult understand the topic.
The actual DNS resolution implementation of Java is faulty.
It's the ONLY service in my Windows machine that couldn't do a correct DNS resolution, stand alone application, Internet Explorer and Mozzilla web pages with applet-
If i use IPs all go fine... when i use domain java fail.
ALL java... non only applet. Also Java Web Start fail.
I controlled proxy, there isn't. i say to java to do a direct connect.
The only thing in my net configuration of strange is the router, a zyxel 660hw... nothing else... my pc work fine with all the rest of the programs that use IPs. Only java is faulty. -
