i ran into some forums and found this:
Hi Graham
I'm making a bit of progress. I found a website that suggested the following
This is a problem of the used sockets with Windows NT. You can request the active sockets with the command netstat. The problem is a function of:
MaxUserPort (default 5000)
KeepAliveTime (default 120)
it suggested the workaround was connection pooling
I have run netstat to look at the number of connections when the problem occurs and waited for the timeout to reset the os back to the minimum and on each occasion my report has run
Does this sound logical?
If so
do you have any examples on connection pooling
it seems that even if i have closed my database connection it still doesn't free my port that was used, that's why i get this error
i am looking for a way to close my db connection and free its socket or port used at the same time, hope you can help,
thanks in advance

Need help on Socket and HTTP

Hi,
I need help ... please ... I have to use socket and not HTTPURLConnection
I try to connect with a socket to a web server (apache2) and request one page but two times.
The first time it works well but the second one it doesn't ... I get a null message.
Why ?
Does the server close the socket as soon as the page is sent ?
If it doesn't how I can continue sending and receiving data on the same socket ?
Here is my code:
package test;
import java.net.*;
import java.io.*;
public class Test
private String laRequete = new String(
"POST http://localhost:5577/Test/ HTTP/1.0\r\n"+
"Host:localhost:5577\r\n"+
"\r\n");
PrintWriter laSortie;
BufferedReader lEntree;
Socket laSocketTCP;
public Test()
String tmp;
try
laSocketTCP = new Socket("localhost", 5577);
laSortie = new PrintWriter(laSocketTCP.getOutputStream());
lEntree = new BufferedReader(new InputStreamReader(laSocketTCP.getInputStream()));
laSortie.println(laRequete);
laSortie.flush();
// Premier essai OK
System.out.println(lEntree.readLine());
while((tmp = lEntree.readLine()) != null)
System.out.println(tmp);
// Second essai => Not OK
laSortie.println(laRequete);
laSortie.flush();
System.out.println(lEntree.readLine());
while((tmp = lEntree.readLine()) != null)
System.out.println(tmp);
catch (Exception e)
e.printStackTrace();
public static void main(String args[])
Test tp = new Test();
Here is the result of the execution
HTTP/1.1 200 OK
Date: Wed, 29 Sep 2004 08:35:35 GMT

Thanks, bye.

Send an HTTP 1.1 request instead of a 1.0 request.
HTTP 1.0 does not support keeping the connection open, so yes, the server closes the connection.

Help regarding ABAP and ABAP Objects

Dear all,
I am very new in abap and abap objects. But i have some expr. in other language..specialy development. Right now i am working for srm module...So i want to move my self into abap object and specialy in workflow...Please provide me help regarding this...along with the starting point for this.
Best Regards

hi
Object Oriented prg
A programming technique in which solutions reflect real world objects
What are objects ?
An object is an instantiation of a class. E.g. If Animal is a class, A cat
can be an object of that class .
With respect to code, Object refers to a set of services ( methods /
attributes ) and can contain data
What are classes ?
A class defines the properties of an object. A class can be instantiated
as many number of times
Advantages of Object Orientated approach
Easier to understand when the system is complex
Easy to make changes
Encapsulation - Can restrict the visibility of the data ( Restrict the access to the data )
Polymorphism - Identically named methods behave differently in different classes
Inheritance - You can use an existing class to define a new class
Polymorphism and inheritance lead to code reuse
Have a look at these good links for OO ABAP-

Help regarding Stacks and Queues.!!!!!!Please....

I have a working program right now..But it lacks some things to be done..It already does the stacks and queues..But still it doesnt print the info on the desired output file outTwo.dat..Both the stacks and queues should be printed on it..Also it has to compute the total commission on categories 1 and 2...and put it again on the outTwo.dat..Any kind hearted people would want to help me here?Here's the assignment detail...Thank YOU!!!!
Q2. Linked List
a.     create a compile AStack class, and a AQueue class similar to the text
b.     provide an application that will:
�     instantiate an AStack object and an AQueue object
�     create a property object for each data line read from the input file assign4.dat
�     push it ti the stack if its is category 1 property; queue if its is category 2; ignore all others
�     print a title called category 1 to an output file called outTwo.dat
�     after printing a few blank lines to outTwo.dat, print a title called category 2 to outTwo.dat
�     traverse the queue and print it to the same output file outTwo.dat
�     print the total commission earned on this category of property to outTwo.dat
Note that for this question you should also print out and submit outTwo.dat. Have Fun!

I need some advanced help regarding AE and PPRO workflow

Hi all.
I have a problem and require a solution. I am creating a video that has cellphone/IM chat graphics, animated in After Effects. The problem is the layering.
In PPRO, the layers are as follows on the timeline.
Top layer: Chat Graphics
Middle Layer: Adjustment layer with colour grade effects
Bottom Layer: Footage
Now the issue I am having is that I need the chat graphics to cast a Gaussian Blur underneath them (the graphics are at 80% opacity) - and I have successfully done this using the AE Adjustment Layer switch, however since the graphics are in AE, and the footage is in Premiere, they blur does not appear. In other words, the graphics in AE are set to blur the layer below itself IN AE, but the footage layer below is IN PPRO.
So... one might think that the obvious solution is to layer it all in AE, using the Replace with AE Composition option in PPRO. However, this means that the adjustment layer for the grade will affect the chat graphics which need to be consistent.
Help...

Just to report back - The Track Matte Key effect worked like a charm.
Just had to create two extra layers in PPro.
One duplicate layer of blurred footage. One duplicate layer of graphics to become the matte, on top of the footage layer.
The effect of Gaussian Blur and Track Matte Key was applied on the footage layer.
Thanks again Richard

Urgent Help Regarding PDF and Word Document Downloading

Many Thanks Shaik for you humble help. Actually now what I did in the past 3 days,
I used Oracle Intermedia to store my PDF and Word Documents in the database using Oracle SQL Loader. Then I used PL/SQL Server Pages and Oracle Web Toolkit for the downloading of my documents.
Now the problem is I saved all my formatted documents in the databse and for retrieval I am using following code in my stored procedure
* Select BLOB Data
select blob_data into myblob from mytable where blob_name = name;
Setup headers which describes the content
owa_util.mime_header('text/html', FALSE);
htp.p('Content-Length: ' || dbms_lob.get_length(myblob));
owa_util.http_header_close;
Initiate Direct BLOB download
wpg_docload.download_file(myblob);
end;
The structure of the mytable table:
create table mytable
doc_id varchar2(128),
doc_name varchar2(128),
blob_data blob
But when it prompt the client to download the file actually it gives the junk file name like 'B104ea56' (which i understand is the address of the blob address). What I want is to show the "SAVE AS" download box with the proper document name which is stored in my field in the following way
1 SALES.PDF
2 PLANNING.PDF
3 MANUAL.DOC
4 STANDARD.TXT
If I set the MIME type for the file format than it automatically starts download the file to the client browser, that I do not want, It should ask the user to download with the proper document name.
Waiting consiously for your help
Regards

Presumedly you'd like those documents being accessiable by users as well, so they should be put on a web server, ftp or nfs sharing. You can just add the urls to those documents, or the directory they are in, into robot system as starting points and let robot run to collect them.

Need help regarding socket programming

hi
i have three machines "W", "D" and "K" on "W" and "D"
i have server programs which listens to port 9999
on "D" and "K" i am running client programs which connects to these servers (from "K" either to "W" or to "D" whichever is available and from "D" to "W")
can this situation ever lead to a BindException

... have three machines "W", "D" and "K" on "W" and "D"Huh? Your explaination doesn't make it clear to me.
Maybe you meant that you have three 'processes' on two different machines?
What kind of socket are you using - TCP or UDP?
Typically a bind exception occurs when the socket is already in use. This can occur if you kill a process and bring it up again. Or if two TCP socket servers on the same box try to start up (one of them will fail to grab the socket.)

Need Help Regarding Users and Roles

Hi,
I have Created a role with Password authentication and in that role only object privilege (SELECT TABLE) and System Privilige (CREATE SESSION)
Now I created user name abbasi and add above role to it and make that role as its default role.
Now when I connect above user from SQL*Plus its Connected.
I want to know since for there is Password Authentication then why during the session databse server not authenticate for role password.
Actually I want to know real usage of password autheticated role.
Regards.
D.abbasi

See the following demo
SQL> conn aman/aman
Connected.
SQL> create user test identified by test;
User created.
SQL> create role test_role ;
Role created.
SQL> grant create session to test_role;
Grant succeeded.
SQL> create role dangerous identified by danger;
Role created.
SQL> grant drop any table to dangerous;
Grant succeeded.
SQL> grant dangerous, test_role to test;
Grant succeeded.
SQL> alter user test default role test_role;
User altered.
SQL> conn test/test
Connected.
SQL> select * from session_roles;
ROLE
TEST_ROLE
SQL> select * from session_privs;
PRIVILEGE
CREATE SESSION
SQL> set role dangerous;
set role dangerous
ERROR at line 1:
ORA-01979: missing or invalid password for role 'DANGEROUS'
SQL> set role dangerous identified by danger;
Role set.
SQL> select * from session_roles;
ROLE
DANGEROUS
SQL> select * from session_privs;
PRIVILEGE
DROP ANY TABLEYou should not make the roles haivng the passwords as the default roles. Let them be there but not as the default roles. These roles can be enabled by the end user when he needs that. In my example, I have made a user TEST, two roles, TEST_ROLE, Dangerous. Dangerous is password protected and contains a priv drop any table. I have made TESt_role as the default role for the user and it becomes active. But for the dangerous,I need to supply the paswword. If I don't , I get an error like I have shown inthe example.

Any Help regarding this would be great!!!So what you are doing is you have a Scanner (hardware: like an HP flatbed scanner) attached to a server that you want to use as a scanning station? Is this the senario that you are talking about?

Need help regarding Simple Data Client and Simple Data Server VIs

Hi everyone.
I have a simple objective. I just want to test the 2 example VIs, "Simple Data Client" and "Simple Data Server" between 2 computers. I just want to check whether is this working between the 2 computers.
What I have done for now is that I changed the "address", from "localhost" in the "Simple Data Client.vi" to the IP address of the computer running the "Simple Data Server". I runned the "Simple Data Server" VI in one of the computers first followed by the "Simple Data Client" in the other computer. Nothing is received and the client just timed out.
Can anyone please help me troubleshoot and tell me what are the possible problems for this? Are there any wires connections between 2 computers that I am missing or any other configurations I have to make before I can successfully do this?
Thanks.
Regards,
Jonathan

Hi Lee.P.
I understand that. I was just feeling frustrated about the project not working. Sincere apologies from me.
I was wrong about the error number. It is not Error 60. It is Error 59 - The network is down, unreachable, or has been reset.. Yes, I have tried changing the port numbers at the 2 computers when trying to send/receive.
Could anything else be the problem?
Regards,
Jonathan
