Sending info to all remote clients
Hi all, I'm creating a chat room application with EJB specification.
When ever a client enters a message, I want all other clients to see it on the main screen. What sort of mechenism should I use for this?
So I implement this code in my business logic?
Thanks for your help.
When ever a client enters a message, I want all other
clients to see it on the main screen. What sort of
mechenism should I use for this?Consider using Message Driven Beans.
So I implement this code in my business logic? You would need a polling process from the client.

}As you see I wrote in commented that I'd like the Thread to send the String to all connected clients, is that possible? If so please tell me how this can be done.
//Thanks ConsiderateHi I've tried the Sockets Tutorial on Sun and found it really great but one >thing. It leaves out the idea of all clients being in touch with each other.Consider that the clients could receive data like jwenting says below which means all traffic MUST be routed through the server
OR you could also have the client open a Socket directly to the other client
and send the data sans server.
georgemc>
Look into multicasting (google is your friend)Unless he wants guaranteed delivery.
sabre150>
but don't expect it to work for clients outside of your intranet.This is true and depending on your router you may not be able to implement a class D address.
jwenting>
So better keep a list of connected clients and loop through that to send the >notifications. Bingo!

Using FetchType.LAZY when sending entity to remote client
Is it possible to use FetchType.LAZY when sending an entity (let's say Person) to a remote client? I'm fine with the fact that a call to person.getAddress() would have to return null o throw an exception of some sort. But, is it possible to even send the Person object when using lazy fetching?
yeah, if you add the CMP jars to the client, it should work, but, if they attempt to introspect the lazy collection, a runtime exception will be thrown since their local copy does not have access to the backing DB... ..I understand the hesitance to have separate object types for different consumers, but, in some cases, it can save time in the long run because you a) avoid these access exceptions and b) have a middle API that can insulate the client or server from changes on the other end (i.e. the server now holds all 'tenants' as a Set, rather then List, but the VO objects still return it as a List so that client code does not need to be updated). You can also find tools to generate the value objects, so your development costs aren't too much hire during the initial release...

My iMac suddenly has a USB problem. I can connect to drives and printers. I am able to pul info off from drives. When I try to send info to a drive or printer, the connection is lost. All USB ports appear to have the same problem. Can anyone help?
Please do 2-3 SMC and PRAM resets back to back and retest. Also use new cables, they can go bad.

Apple Remote Desktop - sending SSH commands to linux clients
Has anyone been able to configure ARD to send SSH commands to linux clients?
The VNC part works, but not sure how to configure the UNIX commands.
We are trying to be able to send rpm, df, etc commands to multiple centos clients at one time...
thanks.not sure how to configure the UNIX commands.
You can't. That's not a feature of ARD. -
Remote client copy fails.
The error message and info is given below. Help me to proceed.
Client copy
The client copy you started has terminated
Client Copy could not start because of Repository differences
Diagnosis
The table definitions differ between the systems. These differences mean that a copy of the data can cause a data loss and system inconsistencies. Differences occur when further developments were not transported or were copied between different maintenance levels.
Procedure
Transport all the developments of table structures between the systems using the Transport Organizer and bring your system to the same development level.
It is observed that some tables are missing in the target system. How do I copy the table structures to the target system?
Thanks in advanceHello Ashraf,
There are repository differences between you source and traget system.
If you want to get the list of repository differences, then run a RFC check before you execute remote clinet copy.
You have to then remove these repository differences before you start with the remote client copy.
to remove the difference you have to:
"Transport all the developments of table structures between the systems using the Transport Organizer and bring your system to the same development level" as mentioned above
I would recommend you to go for Export / Import rather than Remote client copy.
There are several advantages of export import method over remote clinet copy

Hi,
I have performed a remoted client copy of ECP300 to ECQ system using
SAP_ALL Profile and the client copied successfully. After the client
copy some users are complainting that not all data moved over or there
are some major differences. I know the client copy finished but the
users are saying the client copy is not a exact copy of ECP.Are there
any functional or abap post configuration that needs to happen after
this remote client copy? From the client copy logs, it seem like all
the tables got copied over. Please advise as this is very critical.
I have attached 2 issues reported by users and the client copy log with
details. I have also attached the data dictionary differences of the 2
system ECP and ECQ using SCC9 --> RFC SYSTEM COMPARISON.

What is the volume of data you copied. Also have you followed the best practice of minimal/no activity in the source client.
The dictionary differences seems to be becuase of some SPs not applied in your ECP system yet

Trying to write a basic EJB app w/ JPA and remote client
I'm trying to put together a simple sample app that shows a simple stateless session bean that grabs a Java EE 5 entity from the DB and sends it to the remote caller. I have an entity class called Person that simply has getId() and getName() methods.
I'm trying to get a reference to the session bean (using InitialContext.lookup()), which works. Then I try to call a method on that bean, which works as long as the type being returned is not a Person object. I've had the bean always return "Hello" and it works just fine.
Here's the bean code.
@Stateless(mappedName="RolodexSession")
public class RolodexSessionBean implements RolodexSessionRemote {
@PersistenceContext
private EntityManager em;
/** Creates a new instance of RolodexSessionBean */
public RolodexSessionBean() {
public Object getPersonByName(String name)
Query q = em.createQuery("select object(o) from Person o where o.name=:n");
q.setParameter("n",name);
List results = q.getResultList();
if (results.isEmpty())
return "emtpy";
// this would work just fine...
// return "Some string";
// but this doesn't work at all
return results.get(0);
}Here's the client code...

at clientapp.Main.<init>(Main.java:33)
at clientapp.Main.main(Main.java:41)I'm running this on the Sun Java System App Server 9.0.
Any ideas?I've narrowed down the issue. The Person object that I'm trying to send back has a one-to-many relationship with Address objects. I have this all setup correctly, I think. Here's the code from Person.java that establishes that relationship.
* Holds value of property addresses.
@OneToMany(mappedBy = "person")
private List<Address> addresses;
* Getter for property addresses.
* @return Value of property addresses.
public List<Address> getAddresses() {
return this.addresses;
* Setter for property addresses.
* @param addresses New value of property addresses.
public void setAddresses(List<Address> addresses) {
this.addresses = addresses;
}In Address.java I have the other side of the relationship defined (again, correctly, I think).
IF I COMMENT OUT THIS RELATIONSHIP EVERYTHING WORKS! So, the problem seems to be related to using foreign key associations. Is there something I'm missing here? Perhaps it's related to lazy-loading of foreign keys? -
Sending exceptions back to the client : in return object or in a SOAPFault?
Hi.
A question for all the JAX-RPC/SOAP experts out there.
What is your recommendation for the cleanest way to handle exceptions in a Java web service and send the info back to the client ?
I am considering two options :
1- Put the exception info in fields of the object returned by the web service method.
2- Throw a SOAPFaultException and add any necessary info in the Detail attribute of the Exception using a SAAJ SOAPFactory. In this case, how does the client retrieve the SOAPFaultException attributes ?
What is the best option ? Pros and cons ?
Thanks in advance.
FabienIt throws jvm bind error. Please show the full exception stack trace and the block of code it occurs in. The server shouldn't be trying to do a bind at this point.

Is this possible? -- The servlet itselt has to update all its clients.
Hi,
I need to update the values of clients pages , when ever a request to the servlet arrives.
namely the servlet has to update all its client's HTML pages,when ever a new request is sent from any one of its clients.
for an example.
consider the value of a variable A in servlet is 1, initially
Three pages[b] m1,m2,and m3 are accessing that servlet
and value of[b] A is displayed in m1,m2 and m3
if m1 calls the servlet and updates the value of A to 2.
Then this updation has to be reflected in m2 and m3 also.
This must not be done by the clients,by refreshing itselt, or by sending a request to the servlet at certain intervals.
The servlet itselt has to update all its clients.
Regards
-John-Not having used pushlets myself, but having heard about them many times before, I took a look at the article.
Interesting. It never closes the connection to the client, so can keep sending additional info. It seems to solve the problem of updating the page. But at what cost?
When does the "updating" of the page stop?
How do you know if the user is still alive?
How many "listeners" will it be able to handle at one time?
Would the users session expire if they left it on this pushlet page? -
Remote Client Copy - Ended in Erros
Hi Friends,
We recently performed a Remote client copy. What we normally do is we restore an latest offline backup of the Prod into an instance built exclusively for performing client copies into our QA system.
So if our actual PROD is ABC ( production ), the replica system is ADC. We restore latest backup onto ADC. Then from ADC we do a client copy onto AQC ( Quality ). We have n number of clients in AQC. When copying into a particular client we are facing this problem of 3 tables not being able to get copied. They are BKPF,LTAK and SOST. It happened twice that the Remote client ended with errors.
It says "Read or conversion error". The detailed error looks like below ;
TAB_COPY_R_CONTINUE LTAK WITH KEY:
I01 0000066362
Read or conversion error system: ADCT500 table: LTAK

We approached SAP and they asked to do a DB reorg, run update statistics on both source and target and then re run the client copy.
Well DB reorg is a big activity so we just updated the statistics and ran again the "recopying errors" but still it is the same problem.
Can anybody please suggest something. Thank you.

Vinod KHi Friends,
My apologies for coming back to you guys so late. I kind of was lost to find a solution for this.
Hi Sanujit,
The database logs dont indicate anything at all about this error or i am not able to locate them.
Rajesh,
There was a table comparison done for these tables properties in both source and target and everything looked ok and confirmed by the application.
At this moment we have anyway decided to go a fresh client copy again as lot of time has already passed and there would be differences in source and target tables.
But anyway could you please tell me the procedure to transport tables between source and target systems?
Hi Anil,
SAP iS ECC 6.0 and Oracle is 10.2.0.4.0
Thanks again for your time and pateince.

Remote client copy performance
Hello experts,
I need an opinion on following possibilities that could speed up remote client copy:
Increasing maximum number of processes for parallel processing in dialog mode?
Increasing the update processes?
Decreasing the undo retention from default 900 seconds to 600 seconds (Oracle) ?
Increase the number of redo log files?
An opinion or any other insights would be highly appreciated.
Thank you,
RohitWell, the answer is maybe.
You did not supply any information about your run and your system, how can we give you good advice? Any of your proposals might speed up the copy process, but we cannot tell (well decreasing the undo retention and changing the update work processes will not change much). If your hardware (cpu/disk/network) is not exhausted, then increase the number of parallel processes.
Besides that these notes contain good hints regarding copy speedup:

Please not be in rush as your SD & MM consultant need to testing some scenarior on sandbox.
As being Basis expert! you should have many comprisions including patch level on both server before initiate the Remote Client Copy.
I will prefer to do the system copy instead the Remote Client copy without downtime on PRD server.
