Should may application use RMI?
Here is the client of a news ticker i have produced. i wish to use client/ server to some how update the news items the client displays. At the moment i am 80% into implementing sockets but with further research am now considering RMI. My only problem is that i have around 2 weeks till my deadline so will not pursue this if it is too much work.
i am using a 2d array in the client code that holds he news item title and URL. Would the RMI server hold this array instead and the client ask for this information at fixed intervals?
help would be greatly appreciated.

Yeah, I would say you could use RMI no problem. You might use UDP if you need more speed, but RMI is fine and will gaurantee message delivery. You could just use JMS or messaging I suppose, or even JMX, or other of a million possible solutions.
I guess I'd do it like this:
Central data (network/data model) is on some server.
When data changes on the server, push out to client (multicast if needed?)
How and what you push (the data) depends on how much data needs to be sent and how often

Hi,
Two questions really:
1) Should I be using RMI
2) If so how much of the program should use RMI
I am about to start building a database driven application. However, I am unsure whether to make it 2-tier not using RMI or 3-tier using RMI.
The various different clients all need to add,update and delete things in the database which will be done over JDBC. However, all the clients also need to be notified of certain activities taking place on any of the other clients, for instance if one client adds a record the other clients need to be informed of this.
I assume that the broadcasting of the these messages to the listening clients would need to be done using RMI or some other distributed systems technology. Is this a correct assumption?
However, when one of the clients does a query on the database should this be done directly, bypassing the servers. I was thinking this as passing record sets from the database server to the application server and then onto the client applicaiton would result in significant network traffic. Therefore, I assume, that for the other parts of the applicaiton which don't involve the broadcasting of information to all the clients I should just make the database connections within the client programs and connect directly to the database. Is this also a correct assumption?
Any comments on this would be much appreciated.
Thanks in advance
Robert MilesHere's the approach that my company took for a database-centered set of applications.
We wanted multi-user access, and we wanted an object interface, because there is substantial application logic that we preferred to put on the server.
The design we created uses
o apiobjects, which are held by clients, and which in turn simply hold references to
o apiserver objects, which belong to a client session, and which in turn simply hold references to
o dbobjects, which belong to the system, and represent the database data being used by one or more active clients.
Note that in this design, RMI is hidden in the apiobjects. It is important, but not to the client, whether or not the apiobject holds real data, or accesses the server and returns the data.
One other note about this architecture: The data is organized into an object tree. The top of the tree is an "entry" object which the client instantiates and uses to log in; the login returns a "server" object, which is the root for accessing all other objects.
For event notification we ask the client to define an event manager, and tell the "server" about it. (There are also some fairly extensive filter definition capabilities.) On the server side, and event manager, when told about an event, searches the sessions for managers to be notified, and notifies them by calling a method on the event manager.
What about other applications accessing the DB? Well we are still discussing this.
o One consideration I can think of is locking. If all your locking can be convincingly consigned to the DBMS, then maybe you can implement a completely-separate access path.
o Another consideration - one not necessarily shared by my colleagues - is that the boundaries around applications are not always rigid, and the first time a new application crosses the RMI-vs_other boundary, well you'll have some work to redo. -

Using my own machine (connected to a network), I tried to test this one out by setting mine as the server and also the client. I did the following:
1. Compile the source code.
2. Use rmic to generate the skeletons and/or stubs from the ChatCallbackImplementation and ChatServerImplementation.
3. Start the rmiregistry with no CLASSPATH
4. Start the server successfully.
5. Start the applet using the AppletViewer command.
It worked fined.
The problem is when I ran the applet using the browser, IE explorer, the dialog boxes, frame and buttons did appear. I was able to do the part of logging on. But after that, the applet seemed to have hang. No message appeared that says I'm connected (which appeared using the appletviewer). I clicked the send button. No response.
I double-checked my classpath. I did have my classpath set correctly. I'm still trying to figure out the problem. Up to now, I don't have any clue what it is.
I will appreciate much if someone can help me figure what's could have possibly been wrong ....
Thanks a lot ...Hi Domingo,
I had a similar problem running applet/rmi with IE.
Looking in IE..view..JavaConsole error messages my applet was unable to find java.rmi.* classes.
I checked over java classes in msJVM, they're not present.
( WinZip C:\WINDOWS\JAVA\Packages\9rl3f9ft.zip and others from msVM installed )
( do not contain the java.rmi.* packages )
I have downloaded and installed the latest msJVM for IE5. ( I think its included in later versions)
@http://www.objectweb.org/rmijdbc/RJfaq.html I found ref to rmi.zip download to provide
these classes. I couldn't get the classes from the site but I managed to find a ref to IBM
site @http://alphaworks.ibm.com/aw.nsf/download/rmi which had similar download.
The download however didn't solve my problems. I was unable to install rmi.zip with
RmiPatch.exe install.
I solved this by extracting the class files from rmi.zip and installing them at C:\WINDOWS\JAVA\trustlib ( msJVM installation trusted classes lib defined in
registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Java VM\TrustedLibsDirectory )
This solved the problem. My rmi/applet worked.
Hope this helps you.

Client-Server using RMI on Win2000
I have a client server application using RMI that works on Win NT4.0 when I am connected
to a network or when the it is not connected (workstation is client and server).
This same application does not work as a standalone (not connected to network) when running
on Win2000. I've been able to start the server (still under Win2000) by adding a Microsoft
Loopback Adapter but the client do (can) not communicate ( see) the server(s) at all.
Does anyone knows the difference between WinNT4.0 and Win2000 network,
configure Win2000 for client-server on RMI loopback?
Thanks,
IsaganiYes, I did. But let me expand on the problem and observations.
Running under Win2000 and connected to the network and working.
- I use netstat -n (a util ) to see how my application is running when it is working.
The port (1101) the apps uses eventually loops back to the system and the app is able
create the multicast sockets it needs and can join the group. And everyone is happy.
When not connected to the network, port 1101 makes a connection back to the system
but somehow the system breaks the loop back, basically throwing an exception.
I do not these problem with WinNT4.0
Any ideas?
Thanks,

Should an application be converted to use ADO?
I'm just an Oracle DBA, not a developer, so maybe my question isn't phrased correctly.
Currently we are using Delphi 5 and Direct Oracle Access (DOA) from allroundautomations ( http://www.allroundautomations.nl/ )
Our developers are considering switching to Microsoft ActiveX Data Objects (ADO) with Delphi 7 instead of DOA.
Is this a good idea? Any caveats, things to consider?
My understanding that when using ADO one also has to choose an OLE DB Provider. I think that we should use whatever driver is written by Oracle. Any reasons not to do that?Whether it's a good idea or not really depends on the specifics of your application.
- I would assume that it would be more work to convert an existing application using DOA to use ADO in Delphi 7 rather than sticking with DOA.
- ADO is significantly more common than DOA, so it should be much easier to find people who are comfortable with ADO if you need additional help, and you should be able to find a lot more samples, tutorials, etc. on the web.
- ADO may be initially less familiar to your developers, which introduces scheduling risks since their estimates will tend to be less accurate.
- ADO (and the underlying OLE DB API) is designed as a "least-common denominator" sort of database API. I'm assuming from the name that DOA is designed to take specific advantage of Oracle functionality. If you're making use of Oracle-specific functionality, make sure you investigate whether and how ADO handles (or fails to handle) that functionality.
My hunch is that if the developers are considering the switch, it's probably a good idea-- they're the ones most familiar with the specifics of the code.
As far as choosing an OLE DB provider, I'd strongly suggest using the Oracle provider. Rarely, you'll hit a bug in the provider that's not present in some other provider, but that would be the only reason in my mind to switch.

Hi:
I am a complete newbie on RMI, I want to know whether the following task should be achieved by using RMI. Basically, I have a java application sitting on a server machine (unix machine), and I want to be able to call that application from another client machine using the command line prompt (client machine is WIN2000). I was told to open a TCP port to do this. Umm, basically, does this task involve RMI at all?
Please give me some general direction on this problem, thanx a lot.You could perform the communication as mentioned, having a process open a server socket on the server machine and wait for information to be sent from a client. You will end up defining the format and protocols used in the communications over the socket, but if sufficiently simple, this approach would work fine.
If you want to send more complex data or commands, or invoke methods on the server from the client, RMI is a good avenue to explore. It requires some infrastructure, however: you must be running an RMIRegistry process on the server, you must properly put your stubs and interfaces somewhere they can be dynamically downloaded (or packaged up with the client), and you must work through various RMI Security issues.
These things are not hard to pick up, however, and the RMI path in the Java Tutorial is a good place to start learning about such things. -
To call methods inside the same application is possible to use RMI ?
hello,
What I should like to know is if RMI can easily be used to implement comunication (calling methods) inside classes that are part of the one same application... This should be a restrict case to use RMI...
The reason to do it come from the need to use the instance of a class knonwing it only as Object... This can be good to do if some code is used for general pupose in many different contexts.
In this case you can pass to the "server class" a parameter 'o' of type Object (all the classes extend Object) of the "customer class" to get back informations if some elaboration happen inside the "server class"...
This purpose is generally implemented with event listeners, but perhaps it could be done easily using RMI too (I dont know it...).
Using RMI in this simple situation, don't should require anything of complicate (stub, .... mashalling parametres....) to have the reference to method of the "customer class" to call. The "server class" already recives a reference of the "customer class" how parameter of type Object, and the mame of the method too.
I propose a simple thoeric example to explain really what I said before:
Class Server {
String methodName;
Object obj;
pubic Server( Oject o , String metName){ // constructor
obj = o;
methodName = metName;
// some thing is done and, at last, the method callbakMethod() is executed
callbakMethod();
}// constructor
public void callbakMethod(){ // this method have the purpose to call customerMethod()
Class c = owner.getClass();
Method m = null;
try {
m = c.getMethod("callBackMethod",null);
* // (1)
// I think that here we could have the possibility to call
// the method customerMethod() belonging to class Customer..
// I don't know if it possible and ... (and if it is possible) I am not able to do it*
}// callbakMethod()
} // class Server
Class Custmer{
public Customer() { // constructor
Server s = new Server (this, "customerMethod");
} // constructor
customerMethod() { // I would this method is called from class Server
// do some thing.....
} //customerMethod
} // class CustomerMy ask is: it is possible to call customerMethod() from the Server class ?...
If the aswer is yes, I wold know the sintax to use to do it, please.
thank you
regards
tonyMrsangeloRMI doesn't help you in the slightest here. You can just realize it all using local method invocation. All RMI does is to make that remote. If the objects aren't remote there is no point.

What kind of version checking should be done for applications using SQLDBC
Hi,
This query is regarding the kind of version checking that an application should do.
Currently I am building my application in MaxDB version of 7.6.05.09, which is the community edition available on the sdn download site currently, this will change to the enterprise edition once we have finalized everything in terms of code and packging etc....
Now when the application is shipped to customer site, what kind of version checking should the application do to ensure that the version of library/kernel/client/sdk it has been built with is consistent with the one that is installed at the customer site.
From what i see SQLDBC exposes the following method for getting version related information.
char * SQLDBC_Environment_getLibraryVersion(SQLDBC_Environment* hdl);
char *getSDKVersion();
SQLDBC_Int4 SQLDBC_Statement_getKernelVersion(SQLDBC_Statement* hdl); (Note: Wondering why should a handle to SQLDBC_Statement be needed to find the Kernel version)
Just to give you little more hint of what i am talking about, for MySQL database we use the functions
mysql_get_client_version and mysql_get_server_version and check that the values returned by these functions are less than the value which was used at build time.
Regards
RajaHello Raja
From the documentation:
const char* SQLDBC::SQLDBC_Environment::getLibraryVersion ()
Returns the version of used SQLDBC runtime.
This is the version of the used SQLDBC library. The version of the loaded
runtime may differ from the version inidacted in the used header. It is our
aim that newer versions of the runtime will run with old applications without
the need to be re-compiling.
Therefore, for compatibility checks, use getLibraryVersion.
getKernelVersion is also available from the connection:
SQLDBC_Connection::getKernelVersion()

Follow-up: the problem is far less frequent now that we disabled local resource attachment via the RDP session, and when it occurs, a logoff/logon to the RDS server seems to prevent the problem for some time, but now it turns out that it has not actually
gone away.
Facts that remain:
It occurs only in the half-dozen RDP sessions established by the MACs, not from RDP sessions established via any of the other 15 or so Windows 7 RDP clients.
It is always C0000006.
It occurs only when accessing EXEs/DLLs via a network drive (whether when initially opening them or when subsequently using them).
But it is not consistently happening to the same user in the same EXE or DLL or same exact part of the EXE.
No, it is not an option to just deploy locally. I still need to find out how/why the RDP client version could result in incomplete loading of network files on the RDS server.
Is there any logging that can be enabled on the server that can help trace exactly what is happening with network file access (not only when opened, but when Delphi later attempts to complete the load or load other components). -
Very Urgent Unable to Launch Application using Web Start using JDK 1.4.2
Hi all
I am very serious issue i have ejb client swing application that uses
RMI to contact a session bean deployed in JBoss now i want the client app to be installed in the client machine using web start . Also i understand i require security permission to access network resources. so i have signed all the JAR files with same certificate created using self certificate avialiable in JDK by default also in the JNLP file in have included the following tag
<security>
<all-permissions/>
</security>
Now when I launch my application using Web start it gives an error that " Unsigned application is trying to access local resources"
I unable to understand what could be the problem . Please help me with the steps to be followed where in client should be able to RMI call to the server
Thanks in Advance
NaveenYou may have tried this already, but you might have to sign the jars via command line, outside any export process from your IDE.
$ jarsigner {filename}.jar {key from keystore}
I also had problems using webstart and RMI through an RCP

How to configure OC4J using RMI/IIOP with SSL
Any help?
I just mange configure the OC4J using RMI/IIOP but base on
But when I follow further to use RMI/IIOP with SSL I face the problem with: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
p/s: I use self generate keystore which should be ok as I can use it for https connection.
Any one can help?

Any client, whether running inside a server or not, has EJB security properties. Table 15-2 lists the EJB client security properties controlled by the ejb_sec.properties file. By default, OC4J searches for this file in the current directory when running as a client, or in ORACLE_HOME/j2ee/home/config when running in the server. You can specify the location of this file explicitly with the system property setting -Dejb_sec_properties_location=pathname.
Table 15-2 EJB Client Security Properties
Property Meaning
# oc4j.iiop.keyStoreLoc
The path and name of the keystore. An absolute path is recommended.
# oc4j.iiop.keyStorePass
The password for the keystore.
# oc4j.iiop.trustStoreLoc
The path name and name of the truststore. An absolute path is recommended.
# oc4j.iiop.trustStorePass
The password for the truststore.
# oc4j.iiop.enable.clientauth
Whether the client supports client-side authentication. If this property is set to true, you must specify a keystore location and password.
# oc4j.iiop.ciphersuites
Which cipher suites are to be enabled. The valid cipher suites are:
TLS_RSA_WITH_RC4_128_MD5
SSL_RSA_WITH_RC4_128_MD5
TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA
SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA
TLS_RSA_EXPORT_WITH_RC4_40_MD5
SSL_RSA_EXPORT_WITH_RC4_40_MD5
TLS_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA
SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA
nameservice.useSSL
Whether to use SSL when making the initial connection to the server.
client.sendpassword
Whether to send user name and password in clear form (unencrypted) in the service context when not using SSL. If this property is set to true, the user name and password are sent only to servers listed in the trustedServer list.
oc4j.iiop.trustedServers
A list of servers that can be trusted to receive passwords sent in clear form. This has no effect if client.sendpassword is set to false. The list is comma-delimited. Each entry in the list can be an IP address, a host name, a host name pattern (for example, *.example.com), or * (where "*" alone means that all servers are trusted. -

Hi,
I developed a web application using HTML5-Offline Application Cache mechanism. Inspite of deleting the cache as mentioned in the above steps, Firefox still maintains a copy of the page in it's cache. Also, a serious bug is, even though we delete all temp files used by Firefox, and open the previously cached page, it displays it correctly, but upon refreshing/reloading it again shows the previous version of the page maintained in the cache.

[email protected]We have had this issue many, many times before including on the latest 3.6 rev. It appears that when the applicationCache has an update triggered by a new manifest file, the browser may still use only its local network cache to check for updates to the files in the manifest, instead of forcing an HTTP request and revalidating both the browser cache and the applicationCache versions of the cached file (seems there is more than one). I have to assume this is a browser bug, as one should not have to frig with server Cache-Control headers and such to get this to work as expected (and even then it still doesn't sometimes).
The only thing that seems to fix the problem is setting network.http.use-cache to false (default is true) in about:config . This helps my case because we only ever run offline (applicationCache driven) apps in the affected browser (our managed mobile apps platform), but it will otherwise slow down your browser experience considerably.
