I have to use RTP and RTSP for transferring the
audio/video streams in real time.
How I can sen and receive RTP packets.
How can I make the RTP Player.
What is the role of JMF in it.
Please suggest me and provide me the codes if
possible.
Thanks alot
shobhit vermaThere are two ways using which you can send and recieve packets using rtp. One without using the SessionManager and the other with.
1.) Not using the SessionManager makes things easy for you but it offers very little flexibility to you. You can do this by just specifying a medialocator pointing to the specific url
2.) Using the SessionManager is what is usually suggested. This process is more complex. First you have to instantiate a RTPSessionMgr to a SessionManager reference using which you can send and receive streams to and from the network. The process is more involved than this and is suggest you read some tutorials to get a better understanding, than me explaining to you the entire process.

How do I rewrite current code for java 1.3

I'm using the code below that is written for java 1.4. I have been told that the company can not push JRE 1.4 to the company, and that I need to write my code for java 1.3. I'm using org.w3c.dom for my create xml, etc.

Are there features of Java 1.4 that you specifically took advantage and are there any particular lines you are having problems with or did you just freak and post it here?
Basically compile it under Java 1.3 and see what complains. I've done several projects that compile under 1.2, 1.3, and 1.4.

How to display the source code for this friggin' file.

Below is a rather lengthy bit of code that provides the behavior and attributes of a web server for OpenCyc. I need to know if I can enter some java to have the HTML source code displayed in a separate text file whenever this class returns some resulting webpage. If you have any ideas it will be greatly appreciated.

JLundan,
I want to thank you for responding to the thread I started on the forum at java.sun.com. Your solution to my problem of needing to print the code of the html pages that the file I included generates was just what I was looking for. However, I have some further questions to ask, if you don't mind. To clarify my task I should say that your rephrasing of the problem is accurate: "You wan't to display the contents of the HTML file that the web server produces in response of client's request?"
Yes, this is what I need to do, but also it needs to display the source code of that html file that the server produces in response to the client's request. Also, in this case, I am the client requesting that the server return some html file, and I'm not sure where the server is. But the webserver.java file that I shared on the forum is on my local machine. I was wondering if I could modify this webserver.java file at my home so that any html file the server returns to me would automatically display the source code. This is a school project of mine and I am stuck on this one thing here.
Further, where would I put the "foo.html" file so it can be written to?
FileOuputStream fos = new FileOutputStream("foo.html");
fos.write(bytes);
fos.close();
Thanks so much for your help. I look forward to your response, at your convenience.

Tips on how to write efficient java code for java mapping

hi
I do not have much knowledge in Java
Can anybody tell me some tips on how to write efficient and optimised java code to be used in java mapping
Thanks,
Loveena

hi D'za,
JAVA in xi
A very important place where you will use JAVA in XI is while doing your Mapping. There will be cases when JAVA MAPPING is the best solution to go for. There are 2 types of Parsers available for JAVA Mapping. DOM Parser and SAX parser. Just got through the following links to understand more on Java Mapping and the APIs available.http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/parsers/package-summary.html http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/Document.html http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/package-frame.html /people/prasad.ulagappan2/blog/2005/06/29/java-mapping-part-i

Need Code For...

Hello i am new to java...I need help code for something i am doing.
Lets say. i have a start date(ex:1/01/03) and end date(ex:1/30/03),I
need to go to the server and get all the information(logs or .txt) between those two date, and save it temp so I can view it. Please help,Thanks alot!

SQL supports the <= >= functionality so that you could look for something like this:
String SQLString = " SELECT * FROM MyTABLE WHERE dbStartDate > '" + strStartDate + "' AND dbEndDate < '" + strEndDate + "'";
You probably would want to modify to use a prepared statement to handle the date conversion. Check out the SimpleDateFormat for parsing a String date to a Date class, remembering there are two "Date" classes types: Util and SQL
If you search the forum on :
SimpleDateFormat
Converting dates
Prepared Statements
Hope this gets you started, and don't forget aobut the API, a great resource....

ADSI does not return proper code for Password Expired

We are trying to modify a vendor supplied system to get it to authenticate using our LDAPs. The vendor app is a hybrid IIS ASP/ASP.NET application so it seems necessary to use ADSI for authentication. We have had the solution working for more than a year, but now we want to expire passwords in our LDAP.
We have been testing with both Netscape Gateway LDAP engine 4.13 and/or Sun One Directory Server Version 5.2. At the moment, the problem I am facing is that I get the same error code from ADSI whether the attempted password is bad or the user DN and password are good but the account has expired. In other words, I cannot differentiate between an expired password and bad typing during the login attempt.
In either case [bad password or password expired], I get, -2147023570 Automation error Logon failure: unknown user name or bad password. I can log in successfully with an unexpired UID/password using the code so it looks like I have no code error. I have tried several times to make sure I am typing everything OK. My results are consistent.
I have found example code on the web that suggests I should be seeing the "error -2147016672 (1 from NDS) - password expired".
Could there be some sort of Netscape or Sun One LDAP configuration parameter that prevents sending the password expired error code/message?
Any other ideas what might be wrong?
We've tested using VB, VBScript [directly] and VBScript in ASP. Always the same results.
Here are the relevant sample lines {in VBScript}
          Set adsDSO = GetObject("LDAP:")
          on error resume next
          Set adsUser = adsDSO.OpenDSObject("LDAP://ourmachine.cusys.edu:portGoesHere/uid=" & UserName & ",o=whatever,c=US", "uid=" & UserName & ",o=whatever,c=US", Password, 0)
          if err.number 0 then
               if err.number = -2147016672 then
                    ' Cannot seem to get here.
                    response.write "Error code: " & err.number & "<P>"
                    response.write "Error code for expired password<P>"
               elseif err.number = -2147023570 then
                    response.write "Error code: " & err.number & "<P>"
                    response.write "Error code for bad credentials<P>"
               else
                    response.write "Error code: " & err.number & "<BR>"
                    response.write err.description & "<P>"
               ' do more stuff ...

Did you check SAP notes? Maybe the OS creates the file in DIR_HOME directory when the path is invalid. Could you check in AL11? You may also add "MESSAGE msg" to the "OPEN DATASET", maybe you'll get more information.

What is the best api for xml parsing?

I think that api comes with j2se is not that good for xml parsing. is there any open source api which is simple,easy and powerful,

JArsenic wrote:
Hey I feel XMLBeans would be a optimal solution for XML parsing as I provides you a whole set of methods to parse your XML tags as Java Objects. And you may download XMLBeans @ http://xmlbeans.apache.org/.
What advantage would that have over JAXB? It already can do all that and is built into Java itself, so you don't need a separate download.
Also: mapping XML to Java beans is a very specific way of handling XML and is definitely not "the best" in all situations.

Code for finding CPU utilisation for executing query

Hi, i need code for finding CPU utilisation for executing the particular query.

Use session tracing, then in trace file you can find cpu utilization for particular statement on each phase: parse, execute, fetch and the overall.
Or You can use the dbms_utility.get_cpu_time (if your database is 10g) in pl/sql:
declare
cpt1 pls_integer;
cpt2 pls_integer;
cputime pls_integer;
begin
cpt1:=sys.dbms_utility.get_cpu_time;
<some code here>
cpt2:=sys.dbms_utility.get_cpu_time;
cputime:=cpt2-cpt1;
end;

Need platform independent java code for TNS PING

Hi, I am able to ping server /ip address. but unable to ping some TNS entry.

Please help.

You don't need to install another JDK, just use the api from 1.2 and you should be fine. You can even use the 1.4 jdk to compile as if it were 1.2 by using the -target option in javac.
