Hi Friends,

You might be able to do it using frames or a popup window. Take a look at this post for more info.

J2EE StartUp Problem, URGENT.

Hi all!
I'm having a problem since friday with the J2EE Engine Startup. The problem is that MMC says me that the server is running but i can access to the server by anyway. The developer trace of the jcontrol process is:

DATE FIELD PROBLEMS - URGENT

I´m having trouble with FormsCentral.
My form is running about 8 months with no problems.
Yesterday people started to complain that the system doesn´t accept any date.
That means the date field restricts date entries, from date dd/mm/aaaa (brazilian format) to another dd/mm/aaaa, but every date that users input in, is considered by the system as invalid, even it´s a correct and valid date right between the interval specified!
I need Help Urgent!!!
I depend on these forms to finish the payrol service from here.
Thanks
I´ll be waiting.

It look like the system accepts just dates starting from the date of today.
I´m testing.
Please help.
Thanks
Message was edited by: SNOWMAUSS
It looks like the system have some problem just with the date 20/10/2013?!
I´ve fixed the problem change the interval from 20/10/2013 to another date and used 21/10/2013 to another date and it works!
But I think something is wrong with the 20/10/2013 date?!
To reproduce the erros just create a new form with date feature with this exaclty configurations and the bug appears:
I´ll keep waiting

Hi
I´ve concluded that the problem persist if the date interval starts at the
specific date "20/10/2013". Don´t know why?!

Need urgent help on file download servlet problem in Internet Explore

I have trouble to make my download servlet work in Internet Explore. I have gone through all the previous postings and done some research on the internet, but still can't figure out the solution. <br>
I have a jsp page called "download.jsp" which contains a URL to download a file from the server, and I wrote a servlet (called DownloadServlet) to look up the corresponding file from the database based on the URL and write the file to the HTTP output to send it back to the browser. <br>
the URL in download.jsp is coded like <a href="/download/<%= currentDoc.doc_id %>/<%= currentDoc.name %>">on the browser, it will be sth like , the number 87 is my internal unique number for a file, and "myfile.doc" is the real document name. <br>
in my web.xml, "/download/" is mapped to DownloadServlet <br>
the downloadServlet.java looks like
tem_name = ... //read DB for file name
// set content type
if ( tmp_name.endsWith(".doc")) {
response.setContentType("application/msword");
else if ( tmp_name.endsWith(".pdf")){
response.setContentType("application/pdf");
else if ( tmp_name.endsWith(".ppt")){
response.setContentType("application/vnd.ms-powerpoint");
else if ( tmp_name.endsWith(".xls")){
response.setContentType("application/vnd.ms-excel");
else {
response.setContentType("application/download");
// set HTTP header
response.setHeader("Content-Disposition",
"attachment; filename=\""+tmp_name+"\"");
OutputStream os = response.getOutputStream();
//read local file and write back to browser
int i;
while ((i = is.read()) != -1) {
os.write (i);
os.flush();
Everything works fine in Netscape 7.0, when I click on the link, Netscape prompts me to choose "open using Word" or "save this file to disk". That's exactly the behavior I want. <br>
However in IE 5.50, the behavior is VERY STRANGE.
First, when I click on the URL, the popup window asks me to "open the file from its current location" or "save the file to disk". It also says "You have chosen to download a file from this location, ...(some url).. from localhost"
(1) If I choose "save the file to disk", it will save the rendered "download.jsp" (ie, the currect page with URL I just clicked, which isn't what I want).
(2)But if I choose "open the file from its current location", the 2nd popup window replaces the 1st, which also has the "Open ..." and "Save.." options, but it says "You have chosen to download a file from this location, MYFILE.doc from localhost". (notice it shows the correct file name now)
(3) If I choose "Save..." on the 2nd window, IE will save the correct file which is "myfile.doc"; if I choose "Open ...", a 3rd replaces the 2nd window, and they look the same, and when I choose "Open..." on the 3rd window, IE will use Word to open it.
any ideas?
</a>

Did you find a solution to this problem? I've been wrestling with the same issues for the past six months. Nothing I try seems to work. I've tried setting the contentLength(), inline vs. attachments, different write algorythms, etc. I don't get the suggestion to rename the servlet to a pdf file.

Help... Super Urgent. Servlet Problem

Anyone can help me this? My servlet wants to connect to another servlet. My supervisor tells me to use socket. This is my code.
Socket socket = new Socket(location, 8210);
          OutputStream os = socket.getOutputStream();
          boolean autoflush = true;
          PrintWriter out = new PrintWriter(socket.getOutputStream(), autoflush);
          ObjectInputStream objIn = null;
          Object obj = null;
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
          out.println("GET "+dir+"?class="+className+"&method="+method+"&machine="+request.getServerName()+"&port="+random+" HTTP/1.1");
          out.println("Host: localhost:8080");
          out.println("Connection: Close");
          out.println();
boolean loop = true;
          StringBuffer sb = new StringBuffer(8096);
          while (objIn==null)
               objIn = new ObjectInputStream(new BufferedInputStream(socket.getInputStream()));
               try
                    obj = objIn.readObject();
                    //Thread.currentThread().sleep(50);
               catch (Exception e)
                    e.printStackTrace();
My supervisor say that as my servlet opens socket connection to the other servlet, the other servlet just have to do outputstream then my servlet can received. I try but can't. Anyone can help me?? Very Urgent. tomorrow is the dateline.

Hi MelonSeed,
I believe that the other servlet needs to open a ServerSocket in order for the two servlets to communicate via a Socket.
Although I haven't tried it, you can open a URLConnection to the other servlet and then open an InputStream for reading the response from the other servlet.
Depending on the URL you use to connect to the other servlet, you will (as I'm sure you know) invoke its "doGet()" or "doPost()" methods.
Also, you may find some relevant examples in Jason Hunter's book, Java Servlet Programming, which are available online.
Good Luck,

DEPLOY PROBLEM URGENT

Hi,
using JDeveloper 10.1.3.3 ADF BC & JSF. Until today we have deployed all our applications to: Standalone Oracle Enterprise Manager 10g Application Server Control 10.1.3.1.0 throught JDeveloper, I would right click on web.xml, create War deployment profile... and then right click test.deploy and Deploy to AppServer, and everything worked fine.
But today we tried to move to:
Oracle Enterprise Manager 10g Application Server Control 10.1.2.0.2
Supported Target Application Servers 10.1.2.0.2
and we cannot deploy any of our applications through JDeveloper, so we tried to do it manually through OC4J Home -> Applications -> Deploy WAR file... browsed and selected test.war entered Application Name and Map to URL... and got following error:
Failed to deploy web application "Test". Failed to deploy web application "Test". . Nested exception
Resolution:
Base Exception:
java.rmi.RemoteException
deploy failed!: ; nested exception is:
oracle.oc4j.admin.internal.DeployerException: Unknown assembly root-tag attribute: xmlns:xsi. deploy failed!: ; nested exception is:
oracle.oc4j.admin.internal.DeployerException: Unknown assembly root-tag attribute: xmlns:xsi
I've googled a bit and found that I should change following tag in web.xml
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee">
with
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
since I've read:
"To be more precise, deployment descriptors which refer to XML Schema definitions are
only used in J2EE 1.4 and later, but not in J2EE 1.3 or earlier.
OC4J 9.0.4.x and 10.1.2.x support J2EE 1.3 while OC4J 10.1.3 supports J2EE 1.4."
Changing that tag underlines following in web.xml and says Element dispatcher not expected, but I can compile and run application without problems:
<filter-mapping>
<filter-name>adfFaces</filter-name>
<servlet-name>Faces Servlet</servlet-name>
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
</filter-mapping>
So I've, rebuilded and created .war and .ear files, and tried to deploy again, but this time I've got the following error:
Failed to deploy web application "Test". Failed to deploy web application "Test". . The evaluate phase failed. The Adapter used in the evaluate may have thrown an exception.
Resolution:
Please call Oracle support.
Base Exception:
java.lang.NoClassDefFoundError
oracle/adf/share/logging/ADFLogger. oracle/adf/share/logging/ADFLogger
I don't know what changes need to be done in my applications (which files to modify) to be able to deploy to Oracle Enterprise Manager 10g Application Server Control 10.1.2.0.2, if anyone has any suggestion or knows what should be done please help, this is quite urgent & important since we plan to migrate all of our applications to this new application server.
Thanks in advance,
Tomislav.

No success at all.
So far what I gathered from the link you posted and tried:
Note:
"J2SE 1.4.2 is in its Java Technology End of Life (EOL) transition period. The EOL transition period began Dec, 11 2006 and will complete October 30th, 2008, when J2SE 1.4.2 will have reached its End of Service Life (EOSL). Customers interested in learning more about Sun's Java Technology Support and EOL policy"
I cannot find the version 1.4.0. so I've downloaded j2sdk1.4.0_04 and installed it.
To configure JDeveloper to build projects with JDK 1.4:
1.Install J2SE 1.4 on the machine running JDeveloper.
2.Configure JDeveloper with the J2SE 1.4 that you installed:
a.In JDeveloper, choose Tools > Manage Libraries. This displays the Manage Libraries dialog.
b.In the Manage Libraries dialog, choose the J2SE Definitions tab.
c.On the right-hand side, click the Browse button for the J2SE Executable field and navigate to the J2SE_1.4/bin/java.exe file, where J2SE_1.4 refers to the directory where you installed J2SE 1.4.
d.Click OK.
3.Configure your project to use J2SE 1.4:
a.In the Project Properties dialog for your project, select Libraries on the left-hand side.
b.On the right-hand side, click the Change button for the J2SE Version field. This displays the Edit J2SE Definition dialog.
c.In the Edit J2SE Definition dialog, on the left-hand side, select 1.4 under User.
4.Click OK in the Edit J2SE Definition dialog.
5.Click OK in the Project Properties dialog.
did that.
When you run an Oracle JDeveloper 10.1.3 application using the Embedded OC4J server, the application is configured for JDK 1.5. If you then try to switch to JDK 1.4, you will see JSP compile failures. To remedy this you need to force the application files to be re-compiled when OC4J is restarted with JDK 1.4. To configure Embedded OC4J to JDK 1.4:
1.Configure JDeveloper 10.1.3.4 according to the steps above.
2.Stop the embedded OC4J server instance.
3.Delete the following directory:
ORACLE_HOME/j2ee/instance/application-deployments ( I guess this is the following directory: C:\JDeveloper\jdev\system\oracle.j2ee.10.1.3.41.57\embedded-oc4j\application-deployments)
4.Start the embedded server again.
did that.
After doing the steps mentioned above I've created new test app with just one page and tried to run, got following error:
OC4J startup failed

Also what do you mean by
Did you install the ADF Runtime libraries from 10.1.3 on the OAS 10.1.2?
In the document you linked to, it says:
Before you can deploy applications that use ADF on third-party application servers, you need to install the ADF runtime libraries on those application servers. You can perform the installation using a wizard or you can do it manually:
*For WebLogic, JBoss, and Tomcat, you can install the ADF runtime libraries from JDeveloper using the ADF Runtime Installer wizard. See Section 34.12.1, "Installing the ADF Runtime Libraries from JDeveloper".
*For WebSphere, you have to install the ADF runtime libraries manually. See Section 34.12.2, "Configuring WebSphere 6.0.1 to Run ADF Applications".
*For all application servers, you can install the ADF runtime libraries manually. See Section 34.12.3, "Installing the ADF Runtime Libraries Manually".
but we're not using third party app servers since this is not standalone version, we used tomcat before, now colleague that installed OAS told me it doesn't use third party app servers.
What do you mean by this:
"If you did try including the ADF logger library in your deployment file."
How do I do that?
So now I cannot run embbed app server and test locally using j2sdk1.4.0_04 no matter what I try, and still no luck with deploy. I'm afraid that if I cannot do this with newly created test apps without any complexity, what kind of problems will I have to deal with real production apps...
I'll keep trying and I'll post if I figure out anything,
suggestions and help is more than aprechiated,
thanks in advance,
Tomislav.

Delete data dynamically with JSP and servlet (Very Urgent)

Hi,
I am new with servlets and JSP. On my jsp page I am populating customer names in a drop box from database and I have 3 buttons ADD, DELETE and EDIT.
Now when I press DELETE buttong I am calling delete function which is writen in Javascript on my jsp file only,now I want to pass these selcted values ehich I have stored in an array to be pass to servlet,so I can write Delete query for it and delete.
Could anyone help with sample code>
Here what I am trying to say:
<HTML>
<HEAD>
<script language="JavaScript" type="text/javascript">

</script>
</HEAD>
<BODY>
//calling servlet on action tag of form
<FORM METHOD= 'POST' ACTION='Remove_Customer'>
<form ><INPUT TYPE='submit' NAME='DELETE' VALUE='DELETE' onclick="remove()"></TD></form>
<form><INPUT TYPE='submit' NAME='MODIFY' VALUE='MODIFY' onclick="modification()" ></TD></form>
</BODY>
</HTML>
PLEASE HELPME,it's very urgent.
Since the selected Array is in javascrip language , I don't know how can I pass that to servlet.
request.getParameter is not working,since it's an array
Many thanks in Advance.

Hey,
I am having problem deleting multiple values.
If I just select one value,it deletes it
But for multiple values the code is not working right.
If there 2 values selcted then the last value gets deleted,if there are more than 2 values selected none values delete.
Could plese check the code,and let meknow what mistake am I doing?
Please help
String delName="";
int pos = tStr.indexOf(",");
System.out.println(pos);
     if (pos != -1)
               delName = tStr.substring(0, tStr.indexOf(","));
          tStr = tStr.substring(tStr.indexOf(",") + 1 );
               System.out.println("DElName:"+delName);
               System.out.println("tStr::"+tStr);
                    delName = tStr;
                    delete_Customer(delName);
Thanks

Request.getParameter() values in servlet? Urgent

String str=request.getParameter();
I am facing a problem when i submit the arabic values from hidden form fields using javascript.
In servlet when i tries to retrive the arabic values stored in the session, it displays only
garbage values(ie. ?????????).
How to solve this problem?
Please clarify and if possible give some samples.
Thanks & Regards,
Govindaraman

Hi Govindaraman,
in O'Reilly's Servlet book in the internationalization section it describes how. You have to change the String returned into bytes using the proper enconding, then back into a String to it will convert to Unicode.
The basics are this:
String parameterName="your param name";
String encoding = "your charset encoding on the page";
String value = request.getParameter(parameterName);
value = new String(value.getBytes(), encoding);
value is now a Unicode string that should be correctly interpreted.
You can use new String( oldString.getBytes(), encoding) to convert between charsets.

Possibly it's a path problem try to rewrite env-entry-value for clientSDKOptions with either double backslashes or simple slashe.
Furthermore the blanks in the path migth be a reason for your problem.

Comment out process request or rewrite & move it to a position after you read the parameters and connect to the db. Decide where you want to write to the output stream. Also, you have some superfluous casting.
I take it that you are using netbeans? If you debug and step through the code you will get an idea of the flow. The steps should be, midlet connects with POST, doPost is called, server reads parameters, server opens connection, executes query, releases/closes connection, and writes a response to the midlet.
Some notes about the connect method; The scope of rs may cause problems. It is unlike you will have a valid result set if you have a problem with create statement or execute. Take a look at connection pooling and be mindful how the connections are opened, used, and closed; put all the important cleanup operations in a finally. Remove system.exit from your servlet. Actually I would suggest limiting the scope of all your vars;
If you store the username, password, and sid on the midlet, you may have trouble updating the installation base if you need to change the values for any reason. Also, you have clients which contain your database u/p, susceptible to snooping and decompilation. Use the servlet to abstract the db from the client. And use a datasource (with connection pooling) for obtaining connections to db.

I. Brief summary on the architecture of Reports Server, CGI and Reports Servlet
=================================================================================
In order to understand the causes of the error "Unable to communicate with the
Reports Server", let's first briefly review the Reports Runtime Engines, Reports
Server, the Reports CGI, and Reports Servlet architecture.
There are 4 important layers in Reports Server architecture which should be
understood in order to clearly understand the error "Unable to communicate with
the Reports Server" :
1) The Runtime Engines : This is the main layer where the reports are actually
executed. On unix systems there are "rwrun60" and on NT systems there are
"rwrun60.exe" processes.
2) The Reports Server : The Reports Server recieves the job request and queues
it. When one of its runtime engines becomes available, it sends the
command line to that runtime engine for execution. On Unix systems it is
the "rwmts60" executable and on NT systems it is "rwmts60.exe".
3) The Reports CGI : The Reports Web CGI passes the request to the Reports Server.
The Reports CGI or Servlet converts the request to a command line that can be executed by the Reports Server and
submits it to the specified Reports Server. On Unix platforms this executable
is "rwcgi60" and on NTs it is "rwcgi60.exe.
4) The Reports Servlet : Its functionality and function is just the same as "Reports CGI", but it is
a program written in Java as difference to the CGI program (which is
written in C programming language).
The Reports Server may be running on the same server with the CGI program (or
servlet) OR may reside totally on another machine which does not necessarily have
the same Operating System. For instance CGI may reside in a Windows NT machine
while the Reports server may reside on a Unix box, or any other combination with
Unix-Linux-NT-2000, etc.
The reports are called with a URL similar to below with the CGI :
http://fully.qualified.server.name:PORT/dev60cgi/rwcgi60.exe?server=<REPSERVER>&other_parameters=...........
where fully.qualified.server.name is the name of the server where the Reports CGI
reside, and <REPSERVER> is the name of the server.
II. Sources of errors encountered when running a report with Reports Server
============================================================================
The Reports Web CGI (or the Reports Servlet) makes a call to the Reports Server
and asks it to place the output into some destination (defined by DESTYPE and
DESNAME parameters), then gives back the necessary response to the calling
program. For example if the DESTYPE is "cache", then the Reports server generates
the report to a file in a temporary place and gives it back to CGI and the CGI gives
it back to the calling program. Otherwise, if the DESTYPE is "file", the Reports Server
generates the report output to the requested file and the CGI replies back the
following message : "Report output was successfully written to requested
destination.".
If there is any error in this process, the related error message is returned. The
possible sources of errors can be categorized as follows :
1) The errors that are returned from Reports Server; like the Reports Server can
not find the requested RDF file or the report may be run to file and the
directory where the reports output is asked to be placed does not occur or
similar errors. (Usually the REP-XXXX errors)
2) Another possible cause of error is the errors returned by the RDBMS to the
Reports Server, for example a table not found error or things like that. Of
course from the CGI point of view these errors are again transmitted from the
Reports Server but in fact the error originates from the RDBMS. (Usually the
ORA-XXXX errors)
3) Another possible cause of errors is the CGI itself, for example when the CGI
executable can not connect to the requested Reports Server, then we get the
famous "Unable to communicate with the Reports Server". In this document we will
diagnose the common reasons of this last error.
III. How the CGI (or the Reports Servlet) communicates with the Reports Server
===============================================================================
Having said that "Oracle Reports Server CGI - Unable to communicate with the
Reports Server." error is returned back from the CGI itself, let's discuss the
issue of how the Reports CGI connect to the Reports Server. The name of the
Reports Server given in the URL with "server=....." parameter is, in fact, just
a special tnsnames alias, similar to aliases for database connect strings. As it is
important for the CGI to resolve the alias, the CGI needs to know the HOST name (or the
IP) of the machine where the Reports Server is running and the port on which the
Reports Server is listening. So a typical Reports Server alias is defined as follows :
REP60_<MACHINE>=(ADDRESS = (PROTOCOL = tcp)(HOST = <MACHINE>)(PORT = <PORT>))
This is defined in tnsnames.ora file, and the sqlnet.ora file is also used in
the name resolving operation.
IV. Possible reasons which lead to "Unable to communicate with the Reports Server" error.
==========================================================================================
The possible reasons for the "Unable to communicate with the Reports Server" error :
1) Reports Server is up and running :
Make sure that the Reports Server is really running on the specified server
and listening on the specified port. For details have a look at above
explanations for tnsnames alias of the reports server. And because of this the
CGI could not establish a connection to the Reports Server.
2) tnsnames.ora and sqlnet.ora problems :
As described above, the CGI resolves the details for the reports server using
the "tnsnames.ora" and "sqlnet.ora" files. There may be a problem with them,
here are the possible configuration problems :
a) There is no alias in the tnsnames.ora file for this Reports Server
b) The CGI looks into the wrong directory for the "tnsnames.ora" and "sqlnet.ora"
files. By default the CGI checks the $ORACLE_HOME/net80/admin directory for
these scripts, where the $ORACLE_HOME is the home of the Forms & Reports
installation. Please note that in a typical 9iAS 1.0.X installation there
are two ORACLE_HOME's, one is for the iAS and the other is for the tools,
usually the home for the tools is a directory with name "806" on NT and
"6iserver" on unix systems. By defining TNS_ADMIN in the environment, one
can override the search path for these two files.
The TNS_ADMIN variable can be defined in one of the following places :
i) In the environment : On MS Windows platforms check the "Settings
--> Control Panel --> System". On NTs check the environment TAB and in
Win2K systems check the "Environment Variables" button on Advanced tab.
ii) In "6iserver.conf" file. Details are as follows : The main configuration
file for Apache server is "httpd.conf" file which resides in
$IAS_HOME/Apache/Apache/conf directory. In this file there is a line to
include "oracle_apache.conf" and in this "oracle_apache.conf" file
there is a line to include "$ORACLE_HOME/conf/6iserver.conf" file. And
in this file the TNS_ADMIN variable could be defined as follows :
SetEnvIf Request_URI "rwcgi60" TNS_ADMIN=c:\orant\network\ADMIN
Please note that by defining it this way, the TNS_ADMIN will only be defined
for "rwcgi60" calls, so the other parts of the 9iAS will not be affected by
this setting.
c) In sqlnet.ora the "names.default_domain" is set but in tnsnames.ora the
domain is not defined in the alias description. For example if the
"names.default_domain=world" is present and active in "sqlnet.ora" file
then in the "tnsnames.ora" the alias of the reports server should also have
the ".world" extension appended at the end. And another cause is of course
the vice versa for this. If there is no "names.default_domain" is defined
in the "sqlnet.ora" then the alias in "tnsnames.ora" should not have the
domain extension.
Another important point that should be checked is, if TNS_ADMIN is defined
as described above then the search path is as follows, first the directory
defined by TNS_ADMIN is searched, if the "tnsnames.ora" file is not found in
this directory then $ORACLE_HOME/net80/admin is checked. (And on unix systems
/var/opt/oracle is also checked). These directories are only checked if the file
is not present, so if the "tnsnames.ora" file is present in TNS_ADMIN directory
but the alias is not present, then the other directories are not checked at all.
Let us assume that the tnsnames.ora file is present in the TNS_ADMIN directory but
there is no "sqlnet.ora" files here, then the sqlnet.ora file is checked in
$ORACLE_HOME/net80/admin directory, which could cause the same problem if the
"names.default_domain" is defined in this file.
All the above will result in, CGI to unable to resolve the alias in tnsnames.ora
file so it will not be able to establish a connection to the Reports Server.
3) Wrong "ORACLE_HOME" setting :
Wrong ORACLE_HOME setting. This is usually the case for Reports Servlet,
because the environment settings are defined in "jserv.properties" file for the
servlets and the setting here will effect both the Reports Servlet and the
setting for Oracle JSP and other servlets. So the other servlets or Oracle JSP
may need to set ORACLE_HOME to home of HTTP server while the reports server needs
it to be set to the TOOLS_HOME directory. In this case the best alternative is
not to set ORACLE_HOME in this directory and leave it to registry or defined the
ORACLE_HOME in "6iserver.conf" file just like the TNS_ADMIN defined above. For
details please have a look at the following document :
Note 179609.1 "Getting an error Unable to communicate with the Reports Server
using RWSERVLET"
4) Effect of parameter "maxconnect" :
Another common case for this error is that the CGI request reaches the Reports Server but
the Reports Server refuses connection. The main cause for this case is, that the Reports Server
configuration parameter "maxconnect" is defined too low, there are long running reports on the
server or the server is too busy at that time. Usually a second try some
later time results in a successful connection. If this is the case, the end user
may think that the problem is occasional. For details on this case please
have a look at the following document :
Note 125265.1 "Unable to communicate with the Reports Server"
5) Passing very large parameters to reports server :
Another known reason for this error is, if you are passing large parameters
to the Reports Server which exceeds sqlnet transmission blocks then the request may
end up with this error. To test it try with small parameter values. If you hit
this case, the solution is to increase the SDU (Session data unit size) and the TDU
(Transport unit data size) parameters in tnsnames.ora file, for details please
have a look at the following document :
Note 197358.1 "Passing large parameters to Reports show up a Reports Server
error"
6) A case specific to OAS 4.0.8.2 :
If you are using OAS instead of iAS, and the error appeared after
upgrading to 4.0.8.2 then this is caused because the 4.0.8.2 is using RSF
(Required Support Files) version 8.1.6 and the Reports 6i is using 8.0.6 and the
two could not reside in the same ORACLE_HOME directory. So the solution for this
problem is to create a new batch file and use it from which the actual CGI
executable is called. For details please see the following document :
Note 116754.1 "After applying OAS 4.0.8.2 CGI and Cartridge cannot communicate
to report server"
7) A case specific to WEBDB version 2.1.0.9.3 :
Another known case for this error is with WEBDB version 2.1.0.9.3 or less.
If you are using these old versions of WEBDB as HTTP listener, please have a
look at the following document :
Note 95426.1 "URL Not Found When Calling Oracle Developer Report from WebDB Site"

On Windows you can create a Report Services:
rwserver -install server=repserverYou have to choose different names for all servers, like your collegue cannot create a server with the same name. You can start/stop this Report server in Services (control panel). Configuration files can be found under $ORACLE_HOME/reports/conf

Servlet problem: (Shay Shmeltzer / Steve Muench / Frank Nimphius)

Dear sirs... (Shay Shmeltzer / Steve Muench / Frank Nimphius)
I hope you can give me an answer.
I created an ADF UIX application using JDeveloper 10.1.2. I have created a servlet to download files. my problem is that it works just fine using jdeveloper, while when deployed into oracle application server it causes errors.i am calling this servlet by storing filename and data in the session, then sending redirect request to the browser.
the servlet code is:
package view;
import java.io.OutputStream;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.PrintWriter;
import java.io.IOException;
public class FileDownload extends HttpServlet
public void init(ServletConfig config) throws ServletException
super.init(config);
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
try
String DownloadFileName=(String) request.getSession().getAttribute("downloadfilename");
byte data[]=(byte []) request.getSession().getAttribute("downloadfiledata");
if (DownloadFileName==null)
return;
request.getSession().removeAttribute("downloadfilename");
request.getSession().removeAttribute("downloadfiledata");
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment;filename="+DownloadFileName);
response.setContentLength(data.length);
OutputStream OS=response.getOutputStream();
OS.write(data);
catch (Exception e)
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
try
String DownloadFileName=(String) request.getSession().getAttribute("downloadfilename");
byte data[]=(byte []) request.getSession().getAttribute("downloadfiledata");
if (DownloadFileName==null)
return;
request.getSession().removeAttribute("downloadfilename");
request.getSession().removeAttribute("downloadfiledata");
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment;filename="+DownloadFileName);
response.setContentLength(data.length);
OutputStream OS=response.getOutputStream();
OS.write(data);
catch (Exception e)
and the error is :
java.lang.IllegalStateException: Response has already been committed
at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.EvermindHttpServletResponse.resetBuffer(EvermindHttpServletResponse.java:1902)
at com.evermind[Oracle Application Server Containers for J2EE 10g (10.1.2.0.2)].server.http.ServletRequestDispatcher.forward(ServletRequestDispatcher.java:213)
this error is stored in the log file. if i am running this code from JDeveloper I can download the files using either FireFox or Internet Explorer without any error.
but if i am running this code using Oracle Application Server 10g Realse 2, i can not download the files using either FireFox or IE.
so i created another solution, instead of redirecting from a datapage into the servlet, i put the following code in a data page as follows:
public void onDownload(DataActionContext ctx)
String DownloadFileName=getfilename();
byte data[]=getdata();
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment;filename="+DownloadFileName);
response.setContentLength(data.length);
OutputStream OS=response.getOutputStream();
OS.write(data);
OS.flash();
this time the application works fine when deployed into Oracle Application Server if you use FireFox, but if you use IE, it causes problem, i can not save the file or view it.
what is the problem?
how can i fix this?
i am certin that the second method is not correct and it should not be used.
thanks for everyone in advance
best regards

Dear Sir...
Thanks alot for your replay
regarding the reset method. Itried it and it does not give any good.
I discovered the following problem:
If you are redirecting from with struts dataaction page to the servlet, you get the error
Otherwise if you called the servlet from directly or redirected to a servlet from within a servlet, you get no problem.
can any one help me please??
Is it possible that the problem is in IE itself? The file is downloaded perfectly fine with firefox(but the error log still appear)?
best regards

Pricing problem-Urgent

Hi all,
iam getting a problem regarding pricing.
When i make a Sales doc. with reference to an invoice,
everything is being copied from invoice to the sales doc.-customer, material and its no. , sales area, payment terms, incoterms, and material qty. also.
But the pricing of the invoice is not getting copied on to the sales doc.
I have maintained all checks available in the sales doc. type and the item category of the sales doc. type i.e
Pricing: X
and then in OVKK , i have maintained the doc. pric. procedure of the sales doc. type with the pricing procedure of the invoice
and again in the copy control measures, i have maintained
Pricing type: D
But i still not able to copy pricing procedure from the invoice to the Sales doc.
I want the soltn. urgently.
Thanks in advance
Sourav

run VTAF for your sales doc type/bil type
and check item category
set flag for "update doc flow"
and pricing type B
