Each time while application client (153.88.247.15) connecting DPS to read, they will exit with connection reset error.
Could you please kindly give us some suggestion if this error is realted to the DPS?

Unable to read http response from servlet (on nokia 6630 device)

I am sending a http GET request to a servlet for getting some response. Though I am able to obtain the response when I run my j2me app on sony phone I am not able to get any response in case of nokia. On being asked for the APN on nokia I do select the correct one and my settings are correct too. Moreover I am able to connect to the servlet without any problems from my nokia device. However when I tried to read from the Input stream the value returned by read() is -1.
The code works fine on emulator also. Here is the code snippet being used by me. Plz help me solve this problem. Your response shall be definitely appreciated by me.
Code in servlet:
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        String t_username = request.getParameter("user");
        String t_password = request.getParameter("pass");
        URL url = new URL("http://somehost:80/query.cgi?serv=s1&user=" + t_username + "&pass=" + t_password);
        HttpURLConnection head = (HttpURLConnection)url.openConnection();
        head.connect();
        int contentLen = head.getContentLength();
        System.out.println("content length = " + contentLen); //here I get some content length value as expected
        BufferedReader in = new BufferedReader(new InputStreamReader(head.getInputStream()));
        StringBuffer sb = new StringBuffer(contentLen);
        String data = null;
        final String NEWLINE = "\r\n"; //acts as delimiter for parsing response later in my j2me code
        while((data = in.readLine()) != null)
            sb.append(data).append(NEWLINE);
        sb.append(NEWLINE);
        in.close();
        PrintWriter out = response.getWriter();
        out.print(sb.toString());
        out.flush();
        out.close();
        head.disconnect();
    }Code in J2ME:
public static byte[] readFromHttpConnection(String p_URL) throws ConnectionNotFoundException, IOException {
        if(p_URL.startsWith("http://") || p_URL.startsWith("https://")) {
            HttpConnection c = null;
            DataInputStream dis = null;   //tried using InputStream also...still value returned by read() is -1

            c.setRequestProperty("Content-Type", "application/octet-stream");
            dis = c.openDataInputStream();   //able to open this stream
            int len = (int)c.getLength();    //here i get len as -1 for both sony and nokia
            byte[] t_data = null;
            if(len > 0)
                t_data = new byte[len];

                int numRead = 0;
                while((numRead = dis.read(t_data, offset, t_data.length-offset)) > 0) {
                    offset += numRead;
            else //since i get content length as -1 for both sony and nokia, this block is executed, and though
                   //I am able to read data on sony on nokia read() returns value -1 from the start itself
                ByteArrayOutputStream bs = new ByteArrayOutputStream();
                int ch;
                while((ch = dis.read()) != -1)

Strange, this should be fine. You might want to try a more efficient (and shorter and faster) read code:
byte[] buffer = new byte[512];
ByteArrayOutputStream = new ByteArrayOutputStream();
int b;
while((b=dis.read(buffer))!=-1){
bs.write(buffer,0,b);
t_data = bs.toByteArray();No need to check for content length, and always fast. I hope this helps...

Critical: Unable to read locator reference from NCP server

Can't say why/when this started, I just know it's there,
NW 6.5/Sp5,, this occurs both with and without latest post-sp5 patches
( inc libc updates)
If I do a dnipinst from the console and choose the context,
it states that there are allready objects there and warns me from
continuing.
Can't start dns/dhcp console ( the java /ws version)
can't do anything through iManager.
what to do..?? and,, maybe also,, why ?
t.i.a

thanks for that pointer,,
seems like there isn't any,, searched from root, nope,
so,, back to square one I guess,
thanks again,,,

Error: Unable to process the following response from FOI server

One more question about NSDP, Im still wondering how can NSDP work as you only need to declare nsdpInfo.setKeyColumn("xx") --xx
Eg. My result set come from OBIEE, it hase 2 column xx and yy.
Im just copy the sample code to translate the output into xml, the output sample is like:
Column 1 Column 2
440100 0
440200 5
440300 1
So how can MapViewer know that the second column is the value column?
The same question is about when the output is multiple column.

My environment.

Several users, from serveral applications reported then got "No Response from application server".

No response from Web Server

Hello,
I have installed Oracle9i application server Rel 2,9i Infrastructure & oracle 8i DB on Win 2000 server.The installation was successful.
When I access the browser with http://<hostname>:7777 it works fine, it shows HTTP server welcome page.
Now I am trying to access Portal home page using http://<hostname>:7779/pls/portal
It seems, it searches for the Web site for sometime & then gives the error "No response from Web Server"
What is the problem ?? Is there anything with the services ?? I can see two http servers(apps & infrastructure)in the program listing,is it related with these ??
Please help.I will appreciate your support.
Regards
Sandeep

Hi Sandeep.
Try run EM WebSite running in http://<hostname>:1810.
If you are familiarized with this service it should be easy to solve your problem.
Once you access EM WebSite, you'll see two farms(One for iasdb, and one for Portal). That are some symbols that tell you about the status of Portal. If You see an red arrow pointing down, then you need to access Portal farm to put some services "up".
Choose the link for Portal Farm.
This page shows the status of all Portal components.
For you to get response from your portal http server, there a few of these that must be working.
They are (by order):
1. OC4J_Portal;
2. Web Cache;
3. HTTP Server;
For you to start them, you must (for each one) click on it's radio button an choose start.
With this components "up" you should be able to access Portal.
Some of other components cannot be started by us, because it's radio button is disabled, but Single Sign-On:orasso:7777 must be "up", and
Portal:portal:7778 in my case is "down". The rest of OC4J components are needed for other utilities like deploying components.
Hope i helped you.

MediaSource Player: "Response from CDDB server had bad synt

I am using the Creative MediaSource Player as part of the software I got with my SoundBlaster Audigy 2 PCMCIA card. I cannot register to use the CDDB database. I get the error message "Response from CDDB server had bad syntax"?There are many posts here regarding CDDB problems, but none?mention that particular error message. In fact, I Googled it and only two sites came up. But I read all the proposed solutions here and in those two sites, and have tried the following:?. Deleted cddb.db2. Unregistered and reregistered the 4 files mentioned3. Updated to latest version of the software4. Disabled ZoneAlarm5. Tried another app - I CAN successfully access CDDB from Roxio Easy-CD Creator's CD player.6. Manually entered the proxy address that's in IE|Tools|Connections?Has anyone else received this error message? What does it mean? The problem is clearly with the Creative product. Any suggestions?Many thanks,?-- Eric

In the initial customer on that bug, it was not so much the client or what the client was doing, but the fact that it was connecting to the wrong backend IMAP server. If you are going thru the MMP, that should not happen. If you are going thru the webmail server (used by Convergence, UWC, and old webmail), it should not happen. Both of those (MMP and webmail) use the mailHost attribute to determine which backend to connect to. This specific 3rd party software was a different webmail service. It was supposed to be using the mailHost attribute, but it had a bug. So all connections were going to a default backend. And they have set up Distributed Shared Folders -- see:
https://wikis.oracle.com/display/CommSuite/Managing+Shared+Folders#ManagingSharedFolders-ToSetUpDistributedSharedFolders
The key to this bug is that the client has connected to one backend and that backend, for whatever reason, has proxied that connection to a different backend and the bug is in handling errors on that backend-to-backend connection.
We have also seen it happen while moving users. It could also happen if the user is accessing a shared folder owned by a user on a different backend.

How to read .xls file from FTP server t oInternal table

Hi
am using the FTP_SERVER_TO_R3 to read xls file from FTP server to internal table
but the data i get in LT_TEXT is special characters.
CALL FUNCTION 'FTP_SERVER_TO_R3'
EXPORTING
handle = hdl
fname = f_name "ProdDataFromCRM.xls.
* CHARACTER_MODE = 'X'
* IMPORTING
* BLOB_LENGTH =
TABLES
BLOB = lt_text
* TEXT = lt_text
EXCEPTIONS
TCPIP_ERROR = 1
COMMAND_ERROR = 2
DATA_ERROR = 3
OTHERS = 4
can any one help me out to get the exact data..
Really appreciate your quick response..
Thank You

Hi, if you really retrieve an excel file, you can not see the data in ABAP. You may see them in Excel. For this you may use
CALL METHOD document->open_document_from_table
of the interface i_oi_document_proxy for OLE objects. You can access the data with reference to the interface i_oi_spreadsheet.
Please check [Desktop Office Integration (BC-CI)|http://help.sap.com/printdocu/core/Print46c/en/data/pdf/BCCIOFFI/BCCIOFFI.pdf] for details.
But, who knows, perhaps you want "And Now For Something Completely Different".

Getting response from a server

im working on a simple smtp mail sender and i want to get responses to the commands that i post to the DataOutputStream. in all examples on java.sun.com and the net, there is a while block used for reading response from the server.
while((c=is.read()) != -1)
sb.append((char)c);
this code did not work on my application, i changed a bit like below:
/**Get a response from server */
private String getResponse() throws IOException {
int CR = 0, LF = 0;
int c;
char ch;
int count = 0;
StringBuffer sb = new StringBuffer();
while (true) {
c = is.read();
count++;
ch = (char) c;
if (c == -1) {
break;
else if (ch == '\r') {
CR = count;
else if (ch == '\n') {
LF = count;
if (LF - 1 == CR) { //CRLF seen
sb.append(ch);
break;
sb.append(ch);
return sb.toString();
and i use this function in my code as
os.write( ("QUIT\r\n").getBytes());
System.out.println("QUIT : " + getResponse());
this works, because it returns a single line that has a CRLF at the and of line, but if i want to read multi-line responses like greeting messages, i tried to change the code as on the examples like:
/**Get a response from server */
private String getResponse() throws IOException {
int c;
StringBuffer sb = new StringBuffer();
while((c=is.read()) != -1)
sb.append((char)c);
return sb.toString();
this code does not work, because i cannot reach the end of stream. i want to post one command and get one response for that command.
how an algorithm i can develop to solve this problem?
thanks for all help.

i changed the code and it's working well now:
/**Get a response from server */
private String getResponse() throws IOException {
int c;
if((c=is.read()) != -1) {
byte[] b = new byte[is.available()];
StringBuffer sb = new StringBuffer();
is.read(b);
sb.append((char)c);
for(int i=0; i<b.length; i++) {
sb.append((char)b);
return sb.toString();
return "";
if you directly use is.available() when there is no response currently available, it returns 0. we wait for the first character of server response, and then use is.available(). thanks to Kay_Kadner for the idea.
(im a newbie, and dont know how to convert byte[] to String, tried b.toString() but only got meaningless values)

How to decrease timeout value when there is no response from BOE server?

We are using BOE XI R2 .NET SDK to logon BOE XI R2 Server as below as well as using Infoview/CMC logon BOE:
set boSessionManager = Server.CreateObject("CrystalEnterprise.SessionMgr")
set boEnterpriseSession = boSessionManager.Logon(boUserID, boPassword, boCMS, boAuthType)
There is no response for long time from BOE server after I excuting log on BOE using .NET SDK or Infoview/CMC App for more than one minute.
So I want to timeout the logon atction after a certain time such as one minute if there is no response from BOE server.
My question comes:
1. What is the default timeout value for this operation?
    Where can I find it and how to modify it?
2. I found ther are some registry keys on .NET APP Server:
    HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 12.0\Report Application Server\InprocServer\EnterpriseRequestTimeout
    HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Suite 12.0\Report Application Server\Client SDK\CorbaAdapter\WaitReplyTimeout
Are they for the action timeout I mentioned above? If not, what do they work for?
It seems that WaitReplyTimeout is for report data retrieval timeout according to Kbase article 1199286 and which registry setting to change for long running reports, is it correct?
Thanks for any response.
Thanks,
Sunny

I don't think there is a setting available for this. The timeouts you are looking at are essentially how long to wait for a report to process.
My concern about trying to find a setting like this is that if you do get the client (aka SDK) to timeout after one minute, the CMS may still recieve this request shortly after and logon, creating a session that no longer has a handle to it and will then have to wait for it to timeout because of inactivity which would tie up a license.

Error - no response from the server

Attempting to upload my first file (18,888 KB) to the acrobat.com server with this consistent error message:
"Error: Acrobat did not get a response from the server. Try again later or contact your system administrator." When I cancel the message after a retry, the following message appears: "The following files were not uploaded due to an unknown error."
Support yesterday indicated to restart my machine - same result. A bit desperate to get this up and running since I like the whole concept of sharing and presenting technical information. Help!

Did you ever figure out a solution to this problem? I am getting the same message and can't figure out how to fix it. Thanks!

No Response From Application Server-how to overcome this error message

I am Using Oracle 10g Application server. if we run a report from our front end - jsp , if the transaction takes more than 10 minutes then 'No Response From Application Server ' error message is coming in browser. How to over come this. whether i have to set any transaction time in application server. If anybody knows this kindly give reply immediatly.

Can you provide additional background information? Is this a in-house application serviced through an OC4J container or a Report from the Middle Tier install?
Is this request being front-ended by an OHS server? Are there firewalls involved?

Tomcat unable to read accented characters from MySQL

Folks,
Can anyone help with me this problem?
It seems that my version of Tomcat is unable to read accented characters from my MySQL Database.
I've checked in the Database and the characters are all correctly represented there. But when, in my servlet code, I do:
String author = results.getString("author_surname");If the String contains any accented character then the character shows as a '?'. (Even before it gets to the JSP - I'm writing the results straight to catalina.out).
Looking around these forums I found that some people suggested adding
?useUnicode=TRUE&characterEncoding=UTF-8;to the end of my jdbc url. As in:
<ResourceParams name="jdbc/connection">
//a whole load of other params
<parameter>
<name>url</name>
<value>jdbc:mysql://localhost:3306/bookshop?useUnicode=TRUE&characterEncoding=UTF-8</value>
</parameter>
</ResourceParams>inside my server.xml
But it doesn't seem to make any difference. In addition, I doubt I even need to use Unicode as the accents I need are only: �� etc.
(Incidentally, writing that line into my server.xml, tomcat complains that it should finish with a semi-colon. Is that correct? Even if I put in the semi-colon, it still complains!!)
Any suggestions on this would be much appreciated. Thank you.

HI,
From http://download.oracle.com/docs/cd/B10501_01/server.920/a96529/ch9.htm
My understanding is the JDBC Api converts the string from the database to UTF-16.. If so is there any way to disable the UTF-16 encoding at JDBC API?That's exactly what it's supposed to do. There isn't even any concept of what it would mean to disable that: Java characters are UTF-16 representations of Unicode code-points, so there isn't anything else it could do.
I still suspect the JDBC part is working correctly and your writing-to-file isn't. I found this quote in the Wikipedia article on Windows-1256:
Windows-1256 is a code page used to write Arabic (and possibly some other languages that use Arabic script, like Persian) under Microsoft Windows. This code page is not compatible with ISO 8859-6 and MacArabic encodings.So was there a particular reason you chose Cp1256 and not ISO-8859-6 as the charset to write to the file with?

My Ipad 'Systems' shows my WiFi connection is working and all my Apps connect and interact ok but Safari says 'No Response from the Server' the same on my Mail. The WiFi works perfectly on everything else in the house. Any ideas ?

it was not just email it was all internet via safari but all apps including the bank account app. the laptop and pc access the same email servers which work perfectly so it is difficult to blame the servers.
by the way it has now started to work properly at lasst after a whole day of trying to resolve this year.
