Objects communication (urgent)

Hie,
I'm making a project and i'd like to know how to do so that objects (in java) communicate between them independently of the user's intervention ?
Thanks
caroline

i'd like to know how some objects that have no relationship
between them can communicate by sending events to each other.... hmmm... I'm going to go out on limb here and say: THEY DON'T!
If they are sending events to each other then have a relationship via listeners.

What ports need to be open on Fw for Waas Communication--Urgent

Hi All,
This product is new to need your help in configuring this. I am explaining the architecture below:-
We have a requirement to use WAVE-594-K9 Software Release 5.3.1 and in our Manila location and it will not talk to Waas central Manager in our client location instead client has installed one same model Wave-594 in PHX.
So now client has said it will only be used for caching contents and not for optimizing, they have some video training on web which will be passed through this wave and for making them highly/fastly available to agents they want to use this.
We have installed one Wave in Manila in application-accelerator mode and using PBR to redirect the desired traffic via Wave. As per our client Manila Wave will talk to PHX wave and PHX wave will get registered to Waas Manager in client network.
We have firewall between PHX wave & Manila wave, please let me know do we need to opened tcp/udp ports on FW for opening the communication between these two waves?
and what else i need to configure on Manila wave?
This is very urgent quick reply will be highly appreciated!!
Thanks!!
Bhisham

Thanks for the quick reply Kanwal!!
I checked with my team in PHX and we have Juniper FW in between these two Wave's, so what i understand from the links which you have shared.
In Manila Wave i need to configure that in Directed Mode and udp port 4050 needs to be opened bi-directionally on Juniper FW between IPs configured on wave devices.
In Manila we have 10.111.x.189 (Virtual-Blade IP) & 10.111.x.190 IPs & in PHX we 63.149.23.x & 63.149.23.x (VB) so from both IPs we required to open udp 4050 bi-directionally? Want to be sure before raising any request :-)
In PHX wave i am not sure whether we can configure that in directed mode and if it’s not then also it will work by opening port 4050 on FW Right?
In last our client was saying that Manila Wave will only be used as cache engine (VB is configured as content-engine) and it will download contents from PHX Wave (which is registered to CM at client side), what does it mean and do i need to do any special config on wave to achieve this?
I am very new to this device and lot of research on net confused me a lot, please don’t mind!!
Will wait for your reply then only i will raise request with FWteam.
Thanks,
Bhisham

Servlet Applet object communication problem???!!!

Hy folks,
I need to validate the ability of complex Servlet Applet communication an run into my first pb right at the beginning of my tests. I need to have around 200 Applet clients connect to my servlet and communicate by ObjectInput and ObjectOutput streams. So I wrote a simple Servlet accepting HTTP POST connections that return a Java object. When the java Applet get instantiated, the Object Stream communication workes fine. But when the Applet tries to communicate with the servlet after that, I can not create another communication session with that Servlet, instead I get a 405 Method not allowed exception.
Summarized:
- Applet init() instantiate URLConnection with Servlet and request Java object (opening ObjectInput and Output Stream, after receaving object, cloasing streams).
- When I press a "get More" button on my Applet, I am not able to instantiate a new URLConnection with my servler because of that 405 exception, WHY???
Here my Servlet code:
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{
 ObjectInputStream inputFromApplet = null;
 ArrayList transmitContent = null;
 PrintWriter out = null;
 BufferedReader inTest = null;
 try{
 inputFromApplet = new ObjectInputStream(request.getInputStream());
 transmitContent = (ArrayList) inputFromApplet.readObject();
 inputFromApplet.close();
 ArrayList toReturn = new ArrayList();
 toReturn.add("One");
 toReturn.add("Two");
 toReturn.add("Three");
 sendAnsweredList(response, toReturn);
 catch(Exception e){}
 public void sendAnsweredList(HttpServletResponse response, ArrayList returnObject){
 ObjectOutputStream outputToApplet;
 try{
 outputToApplet = new ObjectOutputStream(response.getOutputStream());
 outputToApplet.writeObject(returnObject);
 outputToApplet.flush();
 outputToApplet.close();
 catch (IOException e){
 e.printStackTrace();
}Here my Applet code:
public void init() {
 moreStuff.addActionListener(new ActionListener(){
 public void actionPerformed(ActionEvent e){
 requestMore();
 try{
 studentDBservlet = new URL("http://localhost/DBHandlerServlet");
 servletConnection = studentDBservlet.openConnection();
 servletConnection.setUseCaches (false);
 servletConnection.setDefaultUseCaches(false);
 servletConnection.setDoOutput(true);
 servletConnection.setDoInput(true);
 ObjectOutputStream outputToApplet;
 outputToApplet = new ObjectOutputStream(servletConnection.getOutputStream());
 outputToApplet.writeObject(new ArrayList());
 outputToApplet.flush();
 outputToApplet.close();
 ObjectInputStream inputFromServlet = new ObjectInputStream(servletConnection.getInputStream());
 ArrayList studentVector = (ArrayList) inputFromServlet.readObject();
 area.setText("Success!\n");
 for (int i = 0; i<studentVector.size(); i++) {
 area.append(studentVector.get(i).toString()+"\n");
 inputFromServlet.close();
 outputToApplet.close();
 catch(Exception e){
 area = new JTextArea();
 area.setText("An error occured!!!\n");
 area.append(e.getMessage());
 getContentPane().add(new JScrollPane(area), BorderLayout.CENTER);
 getContentPane().add(moreStuff, BorderLayout.SOUTH);
 private void requestMore(){
 try{
 studentDBservlet = new URL("http://localhost/DBHandlerServlet");
 servletConnection = studentDBservlet.openConnection();
 ObjectInputStream inputFromServlet = new ObjectInputStream(servletConnection.getInputStream());
 ArrayList studentVector = (ArrayList) inputFromServlet.readObject();
 area.setText("Success2!\n");
 for (int i = 0; i<studentVector.size(); i++) {
 area.append(studentVector.get(i).toString()+"\n");
 catch(Exception e){
 area.setText("An error occured2!!!\n");
 area.append(e.getMessage());
 }Can someone help me solv this issue please, this is my first Applet Servlet work so far so I have no idea on how to solve this issue.

Sorry folks, just found my error. Forgot about the ObjectInputStream waiting on the Servlet side, so of course had a dead look...
Sorry!

Problem in System object - Very urgent - Pls help

Hi ,
I have installed Portal version SP9 on windows with MS SQL server as database . I am experencing some
issues during the system object creation for R3 . Below I will specify all the configuration I have done for
system object creation ,
1. I have selected the option Dedicated application server for R/3 system .
2. Under th eproperty category , I have selected Connector and put the following values .
Application Host - 128.1.7.2
Remote Host Type - Select -3
SAP Client - 120
SAP System ID (SID)- DV1
SAP System Number - 00
System Type - SAP_R3
Trace Mode - Select -01
3 . Then Under the property category , Web Application server ( WAS ) I have selected
the following properties .
WAS hostname - 128.1.7.2
Was Protocol - http
4 . Next step I have selected the User Management and put the below details
Logon Method - UIDPW
usermapping type - admin ,user
4. I have also created an alias and made it default
6. Then I have gone to usermapping under the user administration and created the
user mapping for the user .
But when I have tested the system object , I am getting the following error .
SAP Web AS Connection - Jan 1, 1970 8:17:25 AM
Test Details:
The test consists of the following steps:
1. Check that the system object defines an SAP system
2. Validate the following parameters: wap.WAS.protocol; wap.WAS.hostname
3. Check the HTTP/S connection to the defined backend application
Results
1. The system object represents an SAP system.
2. The following parameters are valid: wap.WAS.protocol (http) ; wap.WAS.hostname (128.1.7.2)
3. HTTP/S connection failed. Make sure the protocol, host name, and user mapping are correctly defined.
ITS Connection - Jan 1, 1970 8:17:25 AM
Test Details:
The test consists of the following steps:
1. Check that the system object defines an SAP system
2. Validate the following parameters: wap.ITS.path; wap.ITS.protocol; wap.ITS.hostname
3. Check the HTTP/S connection to the defined backend application
Results
1. The system object represents an SAP system.
2. The following parameters are not valid: wap.ITS.path () ; wap.ITS.protocol () ; wap.ITS.hostname ()
I really dont know what is foing wrong . Do I need to omit the WAS details which I have mentioned in the step number 3 . What is the
real use of this step ? Could any body guide me as this is quite urgent
Thanks
Aneez

Hi,
We have similar setup and having same userids in both R/3 (webas 6.40 based) as well as
in EP 6.0, so we are not doing any user mapping as recommended. I hope i gave all necessary
parameters under system object of categories user management with SAPLOGON, connector
properties and also WAS properties with hostname and type as http. When i try to do test
connection it is giving following error message:
SAP Web AS Connection -
Test Details:

1. The system object represents an SAP system.
2. The following parameters are valid: wap.WAS.protocol (http) ; wap.WAS.hostname (xxxxxxxx)
3. HTTP/S connection failed. Make sure the protocol, host name, and user mapping are
correctly defined.
Test Connection with Connector - Jan 1, 1970 6:40:19 PM
Test Details:
The test consists of the following steps:
1. Retrieve the default alias of the system
2. Check the connection to the backend application using the connector defined in this
system object
Results
Retrieval of default alias successful
Connection successful
Also when i try to do the testing of transaction from :
System Adm.>Support.>SAP Application>SAP transaction>
Select the system and Tcode and most important SAP GUI type = SAP GUI for Windows
i am getting connection broken error.
Let me know is there anything in specific which is missing.
Thanks

Using event for objects communication

hi,
i have two kinds of object, an producer and a consummator, i want to make them communicating with event.
when the producer have information to send, it wrapped within an event an send it to the consummator, do you have some documentation how to do
that, or samples
thanks for your help

// the Producer class...
class Producer
 EventListenerList elList = new EventListenerList();
 public final void addXxxxListener(XxxxListener l)
 this.elList.add(XxxxListener.class, l);
 public final void removeXxxxListener(XxxxListener l)
 this.elList.remove(XxxxListener.class, l);
 // do one of these for each type of XxxxEvent
 // there may be one or more
 public final void fireXxxxYyyyy(<arguments>)
 EventListener[] listeners = this.elList.getListeners(XxxxListener.class);
 if (listeners != null)
 XxxxEvent evt = new XxxxEvent(<arguments>);
 for (int i=0; i<this.elList.length; i++)
 ((XxxxListener)(listeners)).yyyyy(evt);
// this is what you called the Consumator...
interface XxxxListener
extends EventListener
public void yyyyy(XxxxEvent evt);
// the Event class...
class XxxxEvent

Creation of a user with a particular authorization object (Very Urgent)

Hi,
There is a requirement in my project to create a user who can only reset his password. So for this I think a authorization object should be created and assign it to a profile which displays only the tab for reseting the password which is( Logon in SU01). I want to know two things in this regard.
1. The whole process of creating customised authorization object and assigning it to a profile and
2. Any other way to achieve the needed scenario.
Thanks & Regards,
Sujith
Edited by: Sujith K on Feb 4, 2008 1:26 PM

In transaction pfcg ,
give single/composite role name
give profile name and description in authorization tab, save it
enter into change authorization data
select manually tab
give authorization objects name (creating auth. objects)
fields will automatically come inside it
enter the field values
save and generate profiles (Profiles created)
go to su01,
create users (fill address, logon data, roles )
In pfcg,
select the role you created and click on the user comparison for giving the authorization to access.

While doing MI07 it requires a posting to a P&L account for the difference as it is going to be charged off, and if this GL account is a Cost element it will ask for a Assignment to CO object. You can default it in OKB9 for the Gl account based on the profit center and G.L account combination since Profit center will be obtained from the material master assignment it can be done this way.
In transaction MIGO which is for Goods receipt it posts to Fi automatically through the configuration in OBYC. If standard cost is maintained then there may be a posting to price difference account hence it will also be a cost element due t which it required an CO object. For this also you have to maintain a Co object in transaction OKB9
This will solve your problem.

Please follow below steps to handle the same:
1. Go to Transaction: SE10.
2. Create a new workbench request by using key F6.

Trouble with object privileges /urgent, pls !!!/

Hi all !
I've got the next problem.
1. Function in package use dynamic PL/SQL:
snippet:
     stmt :=
     'select ' ||
'r.role_name,' ||
'u.locked,' ||
'u.adm,' ||
'u.ch_pwd_on_next_log ' ||
'from ' ||
     'usr5.c_roles      r,' || --- !!!!!
'usr5.c_users     u ' || --- !!!!!
'where ' ||
     'r.role_id = u.role_id ' ||
'and u.login = :login_ ' ||
'and u.pwd = :pwd_';
2. As default role my user /usr4/ have role with granted
SELECT on usr5.c_roles and SELECT on usr5.c_users.
3. When I execute simple 'select from usr5.c_roles'
from sqlplus - all OK.
4. When I execute stored procedure - I get
error messsage that 'table or view does not exist'.
What's wrong ???
Thanks in advance.
Konstantin.

We cannot build procedures or views using object or system privileges granted to us through a role. You need to get SELECT on usr5.c_roles and SELECT on usr5.c_users granted to your user directly.
This is (of course) in the documentation which states quite clearly that "roles are not meant to be used for application developers".

Applet Servlet communication (urgent)

Hi,
I m using Netscape Enterrpise server 4.0 as my web server. I am passing data from applet to servlet using BufferedInputStream(). But it takes about 30 seconds to send the data. If i don't use it, the data is not being read by the servlet. Is there any alternative to this ? Please help.
Thanks

It's only the primary key field that i am passing to the servlet from applet .. For this particular process, it takes 30 seconds + other things like loading the applet, etc. so in all, it takes about 1 minute just to fetch the data from servlet which is not reasonable. We have monitored the whole process. We found that other things like query, etc. does not take much time, but BufferedInputStream() itself takes 30 seconds. Regarding communication line, it is quite fast. We are a corporate sector, so no doubt about the speed of the communication line ...
Thanks for help.
