EOFException opening input stream in servlet

We are getting intermittent EOFException opening input stream in the servlet.
Out application contains applet running in the browser and accessing servlet. It writes binary data to the output stream (opened from URLConnection) and on server side servlet reads data from the input stream opened from http request object. It worked fine until we moved ear to different box. Now sometime (not always) we get EOFException on the server side opening input stream.
Any suggestions on cause of the problem?
We are running WL 8.1.5
Thanks,
Ed

You have to use WDResource and related classes for reading/writing the files on portal app server.
For getting some Idea, look at this wiki.

When using URLConnection read input stream error

hi,
In my applet I build a URLConnection, it connect a jsp file. In my jsp file I refer to a javaBean. I send two objects of request and response in jsp to javaBean. In javabean return output stream to URLConnect. At that time a error happened.WHY???(Applet-JSP-JAVABean)
Thanks.
My main code:
APPLET:(TestApplet)
URL url = new URL("http://210.0.8.120/jsp/test.jsp";
URLConnection con;
con = url .openConnection();
con = servlet.openConnection();
con.setDoInput( true );
con.setDoOutput( true );
con.setUseCaches( false );
con.setRequestProperty( "Content-Type","text/plain" );
con.setAllowUserInteraction(false);
ObjectOutputStream out;
out = new ObjectOutputStream(con.getOutputStream());
Serializable[] data ={"test"};
out.writeObject( data );
out.flush();
out.close();
//until here are all rigth
ObjectInputStream in = new ObjectInputStream( con.getInputStream() );//happened error
JSP:
TestBean testBean = new TestBean ();
testBean .execute(request, response);
JAVABEAN:
public void execute( HttpServletRequest request,
HttpServletResponse response )
ObjectInputStream in = new ObjectInputStream( request.getInputStream() );
String direct = (String) in.readObject();
System.out.prinltn("direct");
ObjectOutputStream out = new ObjectOutputStream( response.getOutputStream() );
SerializableSerializable[] data ={"answer"};
out.writeObject( data );
out.flush();
out.close();
Error detail:
java.io.StreamCorruptedException: invalid stream header
     at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:729)
     at java.io.ObjectInputStream.<init>(ObjectInputStream.java:251)
     at TestApplet.postObjects(TestApplet.java:172)

you have to pay attention to the sequence of opening the streams.
The following example is: client sends a string to server, and servlet sends a response string back.
client side:
         URL url = new URL( "http://152.8.113.149:8080/conn/servlet/test" );
         URLConnection conn = url.openConnection();
         System.out.println( "conn: " + conn );
         conn.setDoOutput( true );
         conn.setDoInput( true );
         conn.setUseCaches( false );
         conn.setDefaultUseCaches (false);
         // send out a string
         OutputStream out = conn.getOutputStream();
         ObjectOutputStream oOut = new ObjectOutputStream( out );
         oOut.writeObject( strSrc );
         // receive a string
         InputStream in = conn.getInputStream();
         ObjectInputStream oIn = new ObjectInputStream( in );
         String strDes = (String)oIn.readObject();server side
         // open output stream
         OutputStream out = res.getOutputStream();
         ObjectOutputStream oOut = new ObjectOutputStream( out );
         // open input stream and read from client
         InputStream in = req.getInputStream();
         ObjectInputStream oIn = new ObjectInputStream( in );
         String s = (String)oIn.readObject();
         System.out.println( s );
         // write to client
         oOut.writeObject( s + " back" ); I have the complete example at http://152.8.113.149/samples/app_servlet.html

Convert result set into input stream

Hi,
I have result set with me having 93 columns with 1 lac rows. I want to download the result set as xls file.
Because of the data set size is large, i'm not able to hold the data in java object. So i'm trying to convert result set to input stream and giving this input stream to servlet output stream by specifying the contentType as text/xls.
I'm not able to convert result set into input stream.
Could you provide a solution here...
Thanks,
Rajesh

1 - JDBC is the wrong way to extract this data. It's like "What's the fastest way
to copy the Oxford English Dictionary using tweets?" I would research the
DBMS's bulk extract functionality.
2 - Are you dead-set absolutely sure you need to do this at all? What can you
do with the data all in one flat file that you cannot do with SQL access to the
data?
3 - If you want to convert all the columns into one (not that it's a huge
win or anything), you can use the DBMS's conversion and concatenation
functionality in your SQL. So instead of
"select col1, col2, col3, .... from MyBigTable"
do (change this to whatever conversion function syntax and concat syntax your DBMS needs)
"select convert(col1, varchar) concat ' ' concat convert(col2, varchar) concat ' ' concat convert(col3, varchar) ... from MyBigTable"
so the result set you get is a single column.

Hi,
Don't know which of this factors solved the problem:
1. Error server:
AIX 5.2
jdk 1.3.17 (minimum from docu: 1.3.11)
$ORACLE_HOME wasn't in the begining of $PATH
2. success server:

$ORACLE_HOME is now in the begining of $PATH

My suggestion would be to run your code as a plain old Java application. Why use a servlet environment to test the problem? There's just too many things going on. So first see if it works the same way in a Java application. If it does, or if it doesn't, you then know where to go next.

Open an input stream to a socket

How many times I can open an input stream to a socket? If I create more than one an input stream to a socket, does this affect anything?
Thanks.

Generally low level classes do not have high level logic. Socket is a low level class, it's only logic is to connect you to something, and allow you to read and write to that thing (through the socket) using streams. Being able to connect multiple times or setting marks on your stream is a higher level of logic. Putting to much logic is low level classes tends to reduce re-useablility (making unmarkable streams markable as nothing to do with sockets and can be re-used upon any streams that do not support to be marked) and sometimes performances (having marks means having a buffer means having a potential big memory allocation in your Socket that you do not control).
So in your case, since you are not really interested in re-connecting a socket, you should rather go for a wrapping InputStream that provides marking capabilities over the streams used by the socket class itself.
   Socket socket = getSocket();
   // this one does not support to be marked
   InputStream stream = socket.getInputStream();
   // but now it does :)
   stream = new BufferedInputStream( stream );

Re: Connection Failure: ReadFile on fd=1231 failed with err=64 + JVM_recv in socket input stream read

Jon,
I believe that this error is similar to a "connection reset by peer". It is
a Window specific error. I believe it indicates that something has happened
on the other end of the socket such that the socket has gone bad.
I think that this should only occur when people reset their connection
before the reply is sent. I don't believe that it is indicative of any
serious problem other than this communication failure caused by the client.
I've opened an issue to catch and squelch these spurious exceptions rather
than logging them. For now I think it is safe to ignore them.

Adam

Hi Guys,
Using weblogic 5.1 (downloaded pretty soon after announcement) on windows
2000 (yes I know not certified there yet) and using jdk1.2.2-001.
I have a pretty standard setup - a connection pool (5) to a sqlserver
(remote) machine.
A pretty standard multithreaded servlet - grabs a connection, does aselect,
calls dbkona to dump output, releases connection.
It runs fine - browser returns result. When I push 'reload' on browser,say
10 times very quickly, I get the following errors. It is sometimes a
combination of these:

I'm using WLS 5.1 SP11, JDK 1.2.2_007. Win2000.
Does anybody know the cause/solution?
Thanks.

Hi,
I have noticed that applying the service pack helps things quite a bit.
I no longer get NT muxer errors etc etc. just the "connection reset by

As I am repeatedly hitting the server from one browser, your 'connection
going bad' scenario probably
applies quite well.
(btw. before the SP, the errors seemed to crop up more just before/during

10 times very quickly, I get the following errors. It is sometimes a
combination of these:

Now I can get rid of (1) by switching off native IO!! This also stopped IO
exceptions that were being raised by the servlet when it tried to output to
the output stream. (2) persists.
I have changed nothing else in the properties.
(1) sounds like I may need to up the number of file descriptors open?
(2) I don't know. Is my server too loaded? I am running on a 600Mhz using
64Mb heap for the server with 300Mb swap available...

You seem to be adding the contents of CVS directories to the jar file. CVS directories contain internal information used by CVS. This suggests to me that you are either deliberately doing something really really strange, or you are doing something stupid out of ignorance.
The CVS directories suggest you are making a jar from your source code. Generally you compile the source code 'tree' and place the output (.class files etc) in another tree and create the jar from that second tree.
And PaulMiner is correct, you'll definitely need to change 'start' to 'call'. Do that first, then take a look at what is source code, and what it is that you want in your jar file and make sure it is all sensible, I suspect it isn't.

Reset input stream

Is there any way to mark/reset (or something comparable) an input stream that does not support the actual mark/reset methods? I'm using a DataInputStream, which contains a FileInputStream, and I've gotten an IOException saying mark/reset is not supported. Is there any other way to do it?

I'm basically just reading bytes of binary data from a file, and I want to include a feature to reset and start reading again from the beginning. here's some of my code:
public static void readWithDelay() {
        byte buf[] = new byte[100000];
        byte skipbytes[] = new byte[2];
        int length = 0, prevtime, time, lastprevtime=0, num=0, timecheck,skiplength=0;
        long period, filesize=0, bytecount = 0;
        double val = 0.0;
        try {

Sending Control-Z to Input Stream

Hi everyone,
I'm writing an interface to a command line program, and
one of it's features is that it will accept "forms" through
standard input. The default is that notepad will open
when the command is typed, and you can edit the form
through there.
To accept the form through standard input, you have to
send it the form, and then tell it the form is complete.
This is done using the CTRL-Z keypress, at least when
typing the form in with the keyboard.
I need to do this with Java.
There is another post which poses the same question at
http://forum.java.sun.com/thread.jsp?forum=1&thread=3050
so I attempted that solution.. and that didn't work.
I had the system print out the form as it was being written,
and the form displayed properly, followed by what was
supposed to be a CTRL-Z character, which appeared
on screen (DOS Window) as an arrow pointing right.
Here is the code constructing the form and adding what i've been told is "ctrl-z":
new StringBuffer(form+System.getProperty("line.separator")).append(CTRL_Z).append(System.getProperty("line.separator")))CTRL_Z is defined as:
public static final char CTRL_Z = 26;Does anyone have any other suggestions that might be able to help me?
If you need more information/code provided, I can do so.
Thanks for any help!
Kefka.

You can't actually send anything to an input stream. But let's suppose you have an output stream somewhere that is connected to the standard input of this command line program. Try sending a byte, not a character, that contains 26 to it (yes, ctrl-z is indeed 26). This has a better chance of working than the character idea, because Java is going to translate your character-26 from Unicode to bytes using your system's default encoding. And I can't predict what that might end up as. But it will leave the byte 26 alone and just send it... I hope. Can't guarantee this.

How to get file input stream from the client machine by JSF Fileupload API?

Dear Friends,
How to get the file input stream from the client machine by JSF HtmlFileupload or fileupload API. At present, if i execute the file upload code in the client machine, it is able to get the local path of the file and looking for the file in server machine. So i am getting FileNotFoundException.
E.g., If a file is located at client machine at following location means "C:\Test\Test.txt",
uploadClass.getFileuploadComponent().getFilename().toString() returns "C:\Test\Test.txt". But it is looking for that file in server and throwing FileNotFoundException.
Please post your replies soon.
Thanks,
JP

Depends on which version of JSF you're using. If JSF 1.2, I wouldn't even bother trying to hack this into JSF itself unless you can use something like Seam 2 or richfaces.
http://docs.jboss.org/richfaces/latest_3_3_X/en/devguide/html/rich_fileUpload.html
http://docs.jboss.org/seam/2.2.1.CR3/reference/en-US/html/controls.html#d0e29259 (look for s:fileUpload)
But if I were you, a simple non-jsf form with a servlet works best for taking file uploads.
As for JSF 2.0, there are other ways of getting it done.

How to read a file as an input stream after it's posted in an HTML form ?

Hello,
I want to read client file after it's posted in an HTML form. But, I don't want to upload it to filesystem or database. I want to read posted file as an input stream. How can I do that ?
thanks in advance...

A couple of things. If you have a FILE field in your form, the enctype of the form must be multipart/form-data. Check this link
http://www.htmlhelp.com/reference/html40/forms/form.html
Also, when a file is uploaded you cannot use the regular methods to get at the name/value pairs or the file itself. You'll have to use a utility like MultiPartRequest or write your own based on the RFC for Multipart requests.
http://www.servlets.com/cos/javadoc/com/oreilly/servlet/MultipartRequest.html
You will need some temporary file system to store this and then delete it when you are done with it.

JVM_recv in socket input stream error

I've opened a socket and I'm able to access the OutputStream. However, when I try to wrap a ObjectInputStream around the socket's InputStream, I get this error:

What should I be looking for?

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"
location="jdbc/OracleCoreDS"
xa-location="jdbc/xa/OracleXADS"
ejb-location="jdbc/OraclePoolDS"
url="jdbc:oracle:thin:@###.###.#.###:1521:dev1"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="????????"
password="????????"
max-connections="4"
wait-timeout="20"
min-connections="1"
inactivity-timeout="60"
connection-retry-interval="1"
max-connect-attempts="3"
/>
</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:

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:

Hope this helps you.
Good Luck,
Avi.
