Standalone client size transfer limitation to server?

Is it possible a remote client can hit a limit for transfer size to the server
resulting in a REMException? We have a dialup client that is able to navigate
and use our client everywhere but in places where the data object they manipulate
and save are the largest.
Other clients within the customer's WAN have no problem performing the exact same
procedure on the same data object. The client that is failing is using dialup
from puerto rico to the boston area. any ideas?

lose heartbeats for more than 4 minutes the server will assume the
client died and disconnect. We have seen this happen with dial-up
clients and JMS before now. You can set the heartbeat interval higher
if it is affecting you.

How can I deploy a simple stateless ssion EJB and call it from a standalone client

Hi,
I'm creating s simple staless session EJB that has a method that takes a name and prints "Hello" + name. This EJB is in a package called "com.demos.mydemo.ejbs.hello"
How can I deploy this to OC4J?
How can I call it from a standalone client(no JSP, no servlets)?
In Sun's J2EE is very easy to deploy and I don't have to know any XML stuff.
can I use the .ear file created by the Sun's "deploytool" to deploy my EJB to OC4J?

This makes me think that the client can't see the deployed EJB on the OC4J.
How can I fix this problem?

Nabil -
Your standalone client needs to obtain certain server-dependent properties. You can provide them in your code or grab them via a properties file.
For Orion - you need essentially the following setup, filling in your own information...
Define your standalone client class with "main" etc (this is orion specific - should work for 9i AS as well - perhaps there are some differences)
public class SomeClass {
try {
Properties p = new Properties();
p.setProperty("java.naming.factory.initial",
"com.evermind.server.ApplicationClientInitialContextFactory");
p.setProperty("java.naming.security.principal","server_admin_name");
p.setProperty("java.naming.security.credentials","server_password");
// THEN you can get your intitial context reference
InitialContext initial = new InitialContext (p);...........
Then go about your business.....
A good book to get is called "Professional Java Server Programming J2EE Edition" - there happens to be a reasonable amount of Orion/OCJ4 centric information since one of the authors is Karl Avedal - one of the principals behind Orion. Go out to java.sun.com and look at some of the J2EE tutorials - unfortunately a lot of it is hidden behind the J2EE Deployer, but you will get a good sense of what goes into outside-the-container standalone clients.

Classpath for JMS standalone client

Hi,
I observed some problem, when I try to start my JMS client application. If in classpath is oc4j.jar it works, but when I replace oc4j.jar with oc4jclient.jar doesn't
I notice the message:
Exception in thread "main" java.lang.NoClassDefFoundError: com/evermind/server/jms/EvermindXAConnectionFactory
at com.evermind.server.jms.ConnectInfo.getPass(ConnectInfo.java:98)
at com.evermind.server.jms.EvermindTopicConnectionFactory.createTopicCon
nection(EvermindTopicConnectionFactory.java:83)
at sapconnector.MaterialMoverClient.main(MaterialMoverClient.java:52)
the line no. 52 exactly means:
TopicConnection connection = factory.createTopicConnection();
What the OC4J client jar (oc4jclient.jar) is not enough for starting JMS standalone client?
regards
Krzysztof

Hi, thanks for the reply.
Well, I figured out that problem. It was my jar file. One of the jar file, which is imqjmsra.jar wasn't really the right one and that was giving me the problem. Well, at least that is working not, but I am having new problems.
Right, I have been trying to make this work for about three days now. The truth is that my standalone JMS does work, when it is running on the same machine where the J2EE Server is located, but I am trying to make my JMS standalone client to connect to J2EE server from different location. Now I am getting connection refused error. Well, I guess I will be keep trying util I get this working.

Jabber File transfer Limitations?

Hello,
I am looking for documentation defining if there are any limitations for Jabber clients to transfer files with an On-Prem Presence deployment, either for file size or for file type.
I do know that you can dis-allow the feature administratively but that is not what I am looking to confirm.
Thank you,
Casey Nordendale

You can blacklist specific file extensions using the jabber-config.xml file; however, this is a Jabber policy, not a server policy and therefor would not apply to any third-party XMPP clients. The CUP/IM&P server implements XEP-0096 for file transfers. None of the CUP, Jabber, or XMPP extension documentation specifies a file size limit.
Please remember to rate helpful responses and identify helpful or correct answers.

The eclipse IDE is runwith the option -vm D:\bea\jdk160_05\bin\java
In eclipse, i configure to use the same jdk.
When i execute the client outside eclipse, all is ok....
Do you have an idée ?
This is the ejb code :
package test;
public interface IHelloWorld {
public static final String JNDI_NAME = "HelloWorld";
public String sayHello( String name);
package test;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.ejb.TransactionAttribute;
import javax.ejb.TransactionAttributeType;
import javax.ejb.TransactionManagement;
import javax.ejb.TransactionManagementType;
@TransactionManagement(TransactionManagementType.CONTAINER)
@TransactionAttribute(TransactionAttributeType.REQUIRED)
@Stateless( name="HelloWorld", mappedName= IHelloWorld.JNDI_NAME)
@Remote( IHelloWorld.class)
public class HelloWorld implements IHelloWorld
public String sayHello (String name) {
final String msg = "Hello " + name + ". The world is wonderfull...";
System.out.println ( msg);
return msg;
This is the client code :
package client;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import test.IHelloWorld;
public class MainHello {
public static void main (String[] args) throws Exception
Hashtable<String, String> properties = new Hashtable<String, String> ();
properties.put (Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
properties.put (Context.PROVIDER_URL, "t3://localhost:7001");
InitialContext ctx = new InitialContext( properties);
IHelloWorld hello = (IHelloWorld)ctx.lookup ( "HelloWorld#test.IHelloWorld");
String result = hello.sayHello ( "franck");
System.out.println ( result);
ctx.close ();
As you can see it is very simple but doesn't work inside eclipse IDE...

Oracle software purchases come with a CSI number that allows customers to have people contact support for products they own. If you or the organization you are working with has not purchased the product or have other support arrangements with Oracle (some partners have this), then you probably will not be able to obtain the patch from Oracle.
You might be able to try a newer release of the product with an OTN evaluation license, WebLogic Server is currently on version 10.3.3, so you are at least 3 releases behind at this point if you are using 10.3.0.

How do I change the attachment size limit in Calendar Server 6.3, UWC, IWC?

How do I properly increase or decrease the attachment size limit with Calendar Server and all supported user interfaces to it such as WCAP, UWC (Communications Express) and IWC (Convergence)? From my experience with the Outlook Connector, there seems to be some limit imposed by cshttpd on the size of a file upload (I believe I actually got an HTTP error code back on the wcap request indicating something was too big, sorry I don't have it handy, I'll have to re-test). Additionally, it seems UWC imposes additional limits (Example: http://docs.sun.com/app/docs/doc/819-4440/6n6jfgcjh?l=en&a=view&q=fileSizeHardLimit) but I can't seem to get those to work at all. I found many different web.xml related to UWC and I'm not sure which one to change, I tried a couple but had no success because UWC would always report this error if I uploaded between 4-5 megs: com.iplanet.jato.util.WrapperRuntimeException
Root cause = [java.io.IOException: Request cancelled because file input field
"importFile" size is over the configurable limit of 4194304 bytes; see filter init
parameter fileSizeHardLimit]
And it would complain about requestSizeLimit I think if it was over 5 megs, claiming that limit was 5242880. IWC gives a generic error when the upload is too big and rejects it.
I fear that a 4 meg limit will be too imposing and of limited value, so I would either like to raise it, or consider lowering it to 0 bytes so attachments cannot be used at all. I have been looking high and low for information on how to do this and all I can find is the UWC examples. I plan to support the Outlook Connector, UWC, and IWC so the limits should ideally be the same across each. Some of the Exchange data we wish to import does have some attachments so it would be good to continue support for that. I did see some other posts about quota RFEs but at this point I am not concerned about the disk consumption. Can anyone help? Thanks. Please let me know if there is any more information I can provide. I am running SCS6u1 on Solaris 10 SPARC.

Thanks!!! This is working with IWC and I am pretty sure it will work with Outlook. I didn't think to look at config options for mshttpd since I don't have it installed and ics.conf doesn't list the http.service.maxmessagesize and service.http.maxpostsize by default.http.service.maxmessagesize is only relevant to mshttpd, not cshttpd. service.http.maxpostsize applies to both.
UWC is still limiting me though; I'm sure I can reconfigure UWC if I just know which file to edit and if I need to redeploy anything. I'm using the same install paths as the SCS6 Single Host example and I'm not sure which the "uwc-deployed-path" is supposed to be. Again, thanks.If you have deployed UWC/CE to Application Server you would edit the following file and restart application-server:
/opt/SUNWappserver/domains/domain1/generated/xml/j2ee-modules/Communications_Express/web.xml
e.g.
<filter>
    <filter-name>MultipartFormServletFilter</filter-name>
    <filter-class>com.sun.uwc.calclient.MultipartFormServletFilter</filter-class>
    <init-param>
      <param-name>fileSizeHardLimit</param-name>
      <param-value>15485760</param-value>
    </init-param>

    <init-param>

Lookup form standalone client fails with java.lang.ClassNotFoundException

Hi,
I have an issue under Weblogic 11g when a standalone client tries to lookup for an ejb deployed in an ear.
The ear is correclty deployed without any errors and the EJB is correctly defined in the jndi tree (i see it using the jndi browser through the weblogic console).
When my client tries to lookup the EJB using its correct JNDI name, the client receives the following exception :

Jax-ws deployed in standalone client fails with nullpointerexception

I have a project which has deployed successfully as a standalone client with deployed jar files wlfullclient.jar, etc. When I add the jax-ws functions that I require, the deployed client fails with a nullpointerexception that is generated from the constructor of the Service class. The project runs successfully within the JDeveloper 11.1.1.5 environment and on a weblogic 10.3 server platform, but fails when I deploy as a standalone client with the wlfullclient.jar. I'm using JDK 1.6.0_24. In testing, the error occurs when I replace the {WLHome}\server\lib\weblogic.jar entry in the classpath with the wlfullclient.jar.
I tested from another angle by creating my jax-ws functions in a standalone deployment, and it works successfully communicates with the webservices. No additional entries on the classpath besides my deployed jar. I then added to my deployment a simple JMS context lookup:
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY, contextFactoryProvider);
ht.put(Context.PROVIDER_URL, urlString);
Context context = new InitialContext(ht);
This test runs without error in the JDeveloper environment. As soon as I add the wlfullclient.jar in the standalone environment, I get the following exception:
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/xml/ws/spi/ProviderImpl

Interestingly, there is a class com/sun/xml/internal/ws.spi/ProviderImpl in the {JAVA_HOME}/jre/lib/rt.jar file, and I suppose this is what is used by the jax-ws classes when the wlfullclient.jar is not present on the classpath.
So, what is it that I am missing in how to get the jax-ws classes and the jms classes to work in the standalone deployment environment (outside of the JDeveloper environment).

Here is how I solved this problem to execute the application from a jar file (using Oracle Fusion Middleware 11.1.1.5.0 distribution). The key seems to be to extract the contents of the wseeclient.zip file into the same directory as the wlfullclient.jar and ws.api_1.1.0.0.jar files and then ensure that these 2 jars are on the classpath.
In JDeveloper, create a project that has the jms/jax-ws classes.
Put the following text entries to form the classpath (along with other dependent jars, e.g. org.eclipse.persistence...) into a file which will be included in the manifest for the client jar. Be sure to separate entries with a space.
lib/wlfullclient.jar lib/wseeclient.jar lib\ws.api_1.1.0.0.jar lib\org.eclipse.persistence_1.1.0.0_2-1.jar
In the Edit Deployment Profile Properties, select Include Manifest File, specify the main class to execute, and Add the classpath file to be included in the manifest.
Deploy the jar file.
In a deployment area, create the directory that will contain all the classpath jars (e.g. ./lib).
Within the directory ./lib, extract all files from wseeclient.zip (found in {weblogic home}/server/lib)
Copy wlfullclient.jar into the directory ./lib from the {weblogic home}/server/lib
Copy ws.api_1.1.0.0.jar into the directory ./lib from {oracle middleware home}modules
Copy org.eclipse.persistence_1.1.0.0_2-1.jar (for jaxb support) itno the directory ./lib from {oracle middleware home}/modules
Copy the deployed client jar to the deployment area and execute, e.g.:
java -jar ClientTest.jar myArguments

How to create a JMS standalone client with SAS PE8.2 ?

HI everyone,
I use Creator2.1 and I want to write a JMS standalone client that communicate through JMS with a webapp built with Creator.
My pb is that I dont know how to set up initialContext.
Hashtable env=new Hashtable();
env.put(Context.PROVIDER_URL, "mq://localhost:28676/jms");
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.enterprise.naming.SerialInitContextFactory");
context = new InitialContext(env);
factory = (TopicConnectionFactory) context.lookup(factoryName);
For example this code doesnt work and I have the following exception when I try to run my client.

Please refer to http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6377822, particularly the evaluation. Could your situation be the same too (i.e server ip address changing dynamically)? Also, which OS are you using and do you have any firewalls setup that prevents access to port 3700?

Appclication Client deployment in sun application server 8

Hi
Iam new to EJB i was able to deploy and run the EJB sample (ConveterApp) given in the sun's j2ee tutorial....
In all the examples they have mentioned that we have to deploy Application Client to the Server ... and then the server will create a Client-Jar file ... By using that Client Jar file we have to run the client ....
If my standalone-client application and server is in the same machine there is no problem...
if my server is located somewhere else and iam developing a client application in some other machine ...then... DO I need to deploy the client to the server???
If so how can i deploy it to the server ? what are all the files do i require in the client side??

If my standalone-client application and server is in
the same machine there is no problem...
if my server is located somewhere else and iam
developing a client application in some other machine
...then... DO I need to deploy the client to the
server???No you need not. You only need to have the client JAR files so that you code works :)

How to lookup EJBs deployed in OC4J from a standalone client application

Hello all,
I am trying to lookup an EJB deployed in OC4J 10.1.3 from a standalone client application using the following code:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.PROVIDER_URL, "ormi://localhost:23791");
env.put(Context.SECURITY_PRINCIPAL, "jazn.com/test");
env.put(Context.SECURITY_CREDENTIALS, "test");
Context context = new InitialContext(env);
Object ref = context.lookup("ejb/Dispatch");
I get the following error:
javax.naming.NameNotFoundException: ejb/Dispatch not found
     at com.evermind.server.rmi.RMIClientContext.lookup(RMIClientContext.java:51)
     at javax.naming.InitialContext.lookup(InitialContext.java:347)
For the lookup string I've also tried:
"java:comp/env/ejb/Dispatch" and "Dispatch"
For the Context.PROVIDER_URL property I've also tried:
opmn:ormi://localhost:6003:instance
The result is always the same.
I appreciate if someone could help me with this?
Thanks,
Georgi

Georgi,
Your question has been discussed many times on this forum. Search the forum archives for "RMIInitialContextFactory".
The PROVIDER_URL needs to include the name of the deployed application that your EJB is part of, for example:
env.put(Context.PROVIDER_URL, "ormi://localhost:23791/MyApp");The lookup name has to be the value of the "ejb-name" element in your "ejb-jar.xml" descriptor file.
Your SECURITY_PRINCIPAL value looks strange to me. Personally, I use "principals" (and not JAZN), so I modified the "application.xml" file (in the "j2ee/home/config" subdirectory) to use "principals". Look for the following comment in that file:
Good Luck,
Avi.

How Standalone OC4J and the Oracle Application Server linked to each other

Hi ,
Please let me know what is the relation between a Standalone OC4J and the Oracle Application Server ?
In my application The Oracle Application Server is installed in C drive and there is a Stand alone oC4j .
Please tell me how they are linked to each other .
Thank you .

It depends on your need and what features and functionality of Oracle Application Server you are interested in. Note that OC4J is a component of Oracle Application Server that can run as a standalone component or within Oracle Application Server. Question #6 in earlier mentioned FAQ document states:
OC4J standalone is J2EE 1.3 compatible (1.4 and 1.5 too in later releases of OC4J) and is able to be used in both development and small scale production environments. OC4J standalone provides its own inbuilt HTTP/S listener to allow clients to execute Web applications that it has deployed. Application deployment and server configuration of OC4J standalone is performed by the manual editing of a simple set of XML files.
For large scale enterprise deployments, the Oracle Application Server product is likely to be more suitable with its comprehensive feature set including Oracle HTTP Server, process monitoring and management capabilities, and its configuration and management console.
So if you are happy with what you see in standalone OC4J and scalability isn't an issue for you, you can stay with standalone OC4J and don't need to move to Oracle Application Server.
PS: If you do decide to use OC4J that's embedded with Oracle Application Server, you can't move your standalone OC4J inside Oracle Application Server. You will have to reconfigure embedded OC4J again (as you might have done with standalone OC4J) and redeploy your applications.
Hope this helps.
Thanks

Why client is downloading update from server while installing sccm client.

Dear team,
Can anybody give answer to my question?
I am new to sccm so when I am installing any client software the ccmsetup.log file is showing connecting to the server for downloading updates and it's taking long time to downloading because the office network is very slow 512kbps.But my setup file size
is 111MB then what updates are downloading from server and is it possible to put that updates in the offline setup.

You can copy the installer from the SCCM client installers from the SCCM server to the local machine.
Refer to the below for the switches for installation.
Use the switch /source:<Path>
to specify the location of the folder for the installers you copied earlir.

Building a simple J2ME chat client (for own J2SE-based server) Threading Qs

Hi!
I am making my own simple chat / messenger service to use between a couple of friends over GPRS.
On the server side i have made a multi threaded TCP server that opens a new thread for each connecting client and stores these socket connections in a hashtable for access to send data between each thread.
So when a client logs on to the server, the server sends a printwriter message to all other clients informing them of what client connected, and the clients can put the username in its out-database. then the clients can send messages to each others using a simple, self build protocol.
All connection between clients/server happens over a simple printwriter on in/out streams.
Problem is: it works perfectly most of the time.... However, sometimes a message is mysteriously lost when transferred from the server to a client. Transfer from client to server works flawlessly. I am thinking that it might have something to do with the client side threading, or slow network transfer casuing a TCP read error.
Client structure is as following:
start-> Midlet class -> (press connect to server) -> new Client class (impl runnable) -> new thread(this) -> void run() sets up all connections and writers, waits in a while loop for messages from server and takes action according to message type. -> Button(send) uses output stream to send a message to server.
Do anyone have any suggestions on what I must consider when making a client that will simultaniously be able to listen for data from server as well as send data to server over 1 socket and slow mobile connection without causing any trouble?
More info can be provided if necessary.
Thank you!

Building a simple J2ME chat client (for own J2SE-based server)a. i would like to say that this is a bl00dy brilliant idea. i mean ~ its been done before but building one yourself is quite thrilling.
b. are u using java 4 or java 5. ?
sometimes a message is mysteriously lost when transferred from the server to a client. Transfer from client to server works flawlessly.are you using push registry to recieve incoming connections.
i recommend using a StreamConnectionNotifier connection instead of just a socket connection. you could send your data (xml/plain text) just like a stream (tcp ofcourse). if you want to know how to use a StreamConnectionNotifier connection, here's how
try{
// listen at local port 789
StreamConnectionNotifier notify = (StreamConnectionNotifier) Connector.open(http://:789);
// infinite loop to get incoming connections
for(;;)
StreamConnection stream = notify.acceptandOpen(); // return a stream connection when a connection is made
InputStrean mystream = stream.openInputStream();
while(mystream!=-1)
mystream.read();
....cheers
