Problem using myfaces on webLogic

I run into the problem using myfaces on webLogic 9.1.
That is... a managedBean's instance is created twice in one page.
That page is consisted with one <h:inputText> and <h:commandButton>.
After some tests, we found out that the problems happens in a JSP which has <h:inputText>...
This problem didn't happen on Tomcat or JDeveloper.
We tried with another application.
And oh my goodness, it didn't happen.
It worked collect with no problems at all.
The difference between two application is,
the former managedBean extends abstract class,
and the latter doesn't.
Pls help me.....

It was a program bag rather than weblogic's problem.
In the program, it deleted all the objects in the session scope.
So, after JSF render the next JSP, it re-create a managed bean.
But, I'm still wonder why the same things didn't happen in Tomcat.
WebLogic put managed bean into the session soon after JSF
creates it.
On the otherhand, Tomcat does that after managedbean's action
is completed???
Considering the JSF specification, i think weblogic is right.
Cos,JSF put all the components and related managed bean
into session, in the rendering phase.
Thanks for asking anyway.

Know Problems Using JFreeChart + PJA + Weblogic 7.0?

Hello,
I am using Weblogic 7.0 + JDK1.3 running on Solaris
To make use of JFreeChart I am trying to use PJA (Pure Java AWT).
I read that there are some problems with using PJA on Weblogic like Memory Leakage.
Has anyone used PJA till now? If so, could you please let me know if you have any such problems & solutions.
TIA.

I also faced the same problem what I did is
moved all the files from weblogic ant directory into another folder

copied all the jar files from apache-ant-1.6.3\lib to beahome\lib\ant folder
copied all the ant*.* files from apache-ant-1.6.3\bin to c:\bea\weblogic81\server\bin directory

After that, I tried setting permissions for the cwallet.sso file to ugo+rwx, but this leads to the same problems as mentioned above.
My second try was to setup an external WLS 12c, but it seems to be not yet possible to connect to a WLS 12c from within jDeveloper.
Do you have any ideas ?
Thank you in advance for your help.
Regards,
Robin

After debugging the WLS Initialisation with jdb, I recognized that there was some trouble with dependent libraries.
In the end, I solved my problem by using another OS (Ubuntu 11.10) for development. There, the WLS works out of the box, even with 64-Bit libraries.
Thank you for your help.

Robin

Is CN=AliKhosravi, OU=Boors, O=software, L=Tehran, ST=Tehran_Province, C=IR correct?
[no]: y
2. I create my CSR by this command
keytool -certreq -alias ali_alias -keystore ali_keytool.jks -storepass ali120 -file ali_keytool.csr
3. I sign the ali_keytool.csr by openssl . I do it like this :
openssl x509 -req -in ali_keytool.csr -CA certs/myca.crt -CAkey private/myca.key -out ali_keytool.crt -days 365 -CAcreateserial -CAserial my_ca.seq
4.Now my I have a signed certificate (ali_keytool.crt) and my CA certificate (myca.crt)
and I import CA certificate to my keystore
keytool -import -alias Openssl_ca -file myca.crt -keystore ali_keytool.jks -storepass ali120
5. I import the signed certificate into my keystore by alias of private key
keytool -import -alias ali_alias -file ali_keytool.crt -keystore ali_keytool.jks -storepass ali120
6. I import the CA certificate again into a new keystore for creating Trust
keytool -import -alias my_ca -file myca.crt -keystore ali_keytool_trust.jks -storepass ali120
All steps done without any errors
I used this address for help [http://www.startux.de/java/44-dealing-with-java-keystores]
Now I want to configure kestores ans ssl in Weblogic
7. I go to the Environment-->Servers-->AdminServer-->Keystore tab in wblogic
8. I set "Keystores=Custom Identity and Custom Trust", "Custom Identity Keystore = H:\trust\ali_keytool.jks" , "Custom Identity Keystore Type=jks" ,
"Custom Identity Keystore Passphrase:ali120"
"Confirm Custom Identity Keystore Passphrase=ali120"
"Custom Trust Keystore=H:\trust\ali_keytool_trust.jks" , "Custom Trust Keystore Type=jks" ,
"Custom Trust Keystore Passphrase=ali120" , "Confirm Custom Trust Keystore Passphrase=ali120"
9. Then I go to SSL tab and I set "Identity and Trust Locations=Keystores" , "Private Key Alias=ali_alias" ,"Private Key Passphrase=ali120",
"Confirm Private Key Passphrase=ali120"
10. I go to the General tab and select "SSL Listen Port Enabled"
11. I user Firefox as WebBrowser so I configure my Browser I select Tools-->Options-->ViewCertificates --> Authorities tab
and I import the server certificate here is "myca.crt the openssl certificate"
in Downloading Certificate window I select
"Trust this CA to identify web sites"
"Trust this CA to identify email users"
"Trust this CA to identify software developers"
12. I restart Weblogic
13. I try to loging in weblogic like this "https://127.0.0.1:7002/console"
The webBroser show me this warning:
This Connection is Untrusted
You have asked Firefox to connect
securely to 127.0.0.1:7002, but we can't confirm that your connection is secure.
Normally, when you try to connect securely,
sites will present trusted identification to prove that you are
going to the right place. However, this site's identity can't be verified.
What Should I Do?
If you usually connect to
this site without problems, this error could mean that someone is
trying to impersonate the site, and you shouldn't continue.
Technical Details
I Understand the Risks
I don't know why the WebBrowser show me this warning while I imported the Server Certificate
I don't know that my problem is in configuring WebLogic or FireFox WebBrowser or Keystore
If you know please advice me

Has anyone used JAAS with WebLogic?

Has anyone used JAAS with Weblogic? I was looking at their example, and I have a bunch of questions about it. Here goes:
Basically the problem is this: the plug-in LoginModule model of JAAS used in WebLogic (with EJB Servers) seems to allow clients to falsely authenticate.
Let me give you a little background on what brought me to this. You can find the WebLogic JAAS example (to which I refer below) in the pdf: http://e-docs.bea.com/wls/docs61/pdf/security.pdf . (I believe you want pages 64-74) WebLogic, I believe goes about this all wrong. They allow the client to use their own LoginModules, as well as CallBackHandlers. This is dangerous, as it allows them to get a reference (in the module) to the LoginContext's Subject and authenticate themselves (i.e. associate a Principal with the subject). As we know from JAAS, the way AccessController checks permissions is by looking at the Principal in the Subject and seeing if that Principal is granted the permission in the "policy" file (or by checking with the Policy class). What it does NOT do, is see if that Subject
has the right to hold that Principal. Rather, it assumes the Subject is authenticated.
So a user who is allowed to use their own Module (as WebLogic's example shows) could do something like:
//THEIR LOGIN MODULE (SOME CODE CUT-OUT FOR BREVITY)
public class BasicModule implements LoginModule
private NameCallback strName;
private PasswordCallback strPass;
private CallbackHandler myCB;
private Subject subj;
         //INITIALIZE THIS MODULE
           public void initialize(Subject subject, CallbackHandler callbackHandler, Map sharedState, Map options)
                  try
                       //SET SUBJECT
                         subj = subject; //NOTE: THIS GIVES YOU REFERENCE
TO LOGIN CONTEXT'S SUBJECT
                                                 // AND ALLOWS YOU TO PASS
IT BACK TO THE LOGIN CONTEXT
                       //SET CALLBACKHANDLERS
                         strName = new NameCallback("Your Name: ");
                         strPass = new PasswordCallback("Password:", false);
                         Callback[] cb = { strName, strPass };
                       //HANDLE THE CALLBACKS
                         callbackHandler.handle(cb);
                  } catch (Exception e) { System.out.println(e); }
     //LOG THE USER IN
       public boolean login() throws LoginException
          //TEST TO SEE IF SUBJECT HOLDS ANYTHING YET
          System.out.println( "PRIOR TO AUTHENTICATION, SUBJECT HOLDS: " +
subj.getPrincipals().size() + " Principals");
          //SUBJECT AUTHENTICATED - BECAUSE SUBJECT NOW HOLDS THE PRINCIPAL
           MyPrincipal m = new MyPrincipal("Admin");
           subj.getPrincipals().add(m);
           return true;
         public boolean commit() throws LoginException
               return true;
    }(Sorry for all that code)
I tested the above code, and it fully associates the Subject (and its principal) with the LoginContext. So my question is, where in the process (and code) can we put the LoginContext and Modules so that a client cannot
do this? With the above example, there is no Security. (a call to: myLoginContext.getSubject().doAs(...) will work)
I think the key here is to understand JAAS's plug-in security model to mean:
(Below are my words)
The point of JAAS is to allow an application to use different ways of authenticating without changing the application's code, but NOT to allow the user to authenticate however they want.
In WebLogic's example, they unfortunately seem to have used the latter understanding, i.e. "allow the user to authenticate however they want."
That, as I think I've shown, is not security. So how do we solve this? We need to put JAAS on the server side (with no direct JAAS client-side), and that includes the LoginModules as well as LoginContext. So for an EJB Server this means that the same internal permission
checking code can be used regardless of whether a client connects through
RMI/RMI-IIOP/JEREMIE (etc). It does NOT mean that the client gets to choose
how they authenticate (except by choosing YOUR set ways).
Before we even deal with a serialized subject, we need to see how JAAS can
even be used on the back-end of an RMI (RMI-IIOP/JEREMIE) application.
I think what needs to be done, is the client needs to have the stubs for our
LoginModule, LoginContext, CallBackHandler, CallBacks. Then they can put
their info into those, and everything is handled server-side. So they may
not even need to send a Subject across anyways (but they may want to as
well).
Please let me know if anyone sees this problem too, or if I am just completely
off track with this one. I think figuring out how to do JAAS as though
everything were local, and then putting RMI (or whatever) on top is the
first thing to tackle.

Error on using MyFaces component

Hy all,
I don't know if someone as already tested to work with JSF and MyFaces on its WebAS.
In fact I've started by developping a simple JSF page
and next I would like to add some sweet component by using MyFaces and Tomawakh.
For the JSF page, no problem, it rulez, but, when I <b>just</b> add "myfaces-api-1.1.3.jar" and
"my-faces-impl-1.1.3.jar" and deploy it to my server.
No error during deploying but when I'm trying to open a

I mean, in each JSP page I'm trying to use those standard taglib :
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
It crashes.
I've try to add in my web-inf/lib some jar like : servlet_api.jar, servlet.jar, and so on but nothing seam to be working.
I've also try to define the extensionFilter of myfaces in my web.xml but it doesn't help me
Anyone has an idea ? I'll give reward
Thx.

Hy,
try do do this:
1) extract the JSF Tag-Lib's from the Jar-File in a folder under the WebContent folder (in my example named as "tld")
2) Add some TagLib- Entries in the WEB.XML like this:
<taglib>
   <taglib-uri>http://java.sun.com/jsf/core</taglib-uri>
   <taglib-location>tld/jsf_core.tld</taglib-location>
</taglib>
<taglib>
   <taglib-uri>http://java.sun.com/jsf/html</taglib-uri>
   <taglib-location>tld/html_basic.tld</taglib-location>
</taglib>
<taglib-uri> ist the URL that you use in the JSF Pages and <taglib-location> is the location of the expanded Tag-Libary.
The example above ist based on the Sun-Faces components but it works in the same way for Myfaces oder for the Oracle ADF faces.
Instead of the both Jar's myFaces-api and mafaces-imp I have use the myfaces-all.jar.
I hope this informatin will help you.

Using javascript in weblogic 10.3

Hi.. Can anyone help tell me how to use javascript in weblogic 10.3. I've tried the following option:
var form = document.getElementById(lookupIdByTagId("searchForm", this));
var ban = form;
The form object always returns null.

Hi.. Sorry for late reply... I got my problem solved.. May be this could be useful to others.
Use scope id to retrieve values of from elements for Javascript in Weblogic Portal 10.3 :
For ex:
Mention:
<netui:html idScope="sampleScope" generateIdScope="true">
And in javascript function:
var label = document.getElementById (lookupIdByTagId("sampleScope.uploadForm_id","form"))[lookupIdByTagId('sampleScope.name_id',"sampleScope.uploadForm_id")].value;
uploadForm_id is the tagId of <netui:form> and name_id is the tagId of textFeild in that Form.
Hope this is helpful...

Problem using jsp:include from inside a custom tag

Hi, All !
          I have a problem using <jsp:include> from inside a custom tag. Exception is:
          "java.lang.ClassCastException: weblogic.servlet.jsp.BodyContentImpl"
          Apparently, weblogic tries to cast BodyContentImpl to JspWriterImpl and
          could not do this. Is it a bug, since in the 1.1 spec is said: "The
          BodyContent is a subclass of JspWriter that can be used to process body
          evaluations so they can retrieved later on."
          My code is:
          <wfmklist:items>
          <jsp:include page="item.jsp" flush="true"/>
          </wfmklist:items>


This is an area of contention with WL. It is not so tolerant with regards to
          the spec. I spent several days recently trying to convince it to accept the
          specification in regards to bodies and includes and it appears to have
          successfully rebuffed my efforts.
          Frankly, this is very disappointing. It appears that some shortcuts were
          taken on the way to JSP 1.1 support, and the result is a very hard-coded,
          inflexible implementation. As I have not seen the implementation myself, I
          hate to assume this, however one could posit that the term "interface" was a
          foreign concept during the implementation, other than as some annoying
          intermediary reference requiring an immediate cast to a specific Weblogic
          class, which in turn is apparently required to be final or have many final
          methods, as if being optimized for a JDK 1.02 JIT.
          I am sorry that I don't have any positive suggestions other than to use a
          URL object to come back in an execute the necessary "include" directly. You
          lose all context (other than session) and that can cause its own problems.
          However, you can generally get the URL approach to work, and you will
          hopefully avoid further frustration.

How to create an RDBMS event generator using wlst on weblogic 10.3

how to create an RDBMS event generator using wlst on weblogic 10.3, i got a code fragment needing class "com.bea.wli.management.configuration.RDBMSEventGenChannelConfiguration"
but i can' t find this class in classpath on weblogic 10.3, pls help me, thanks. code sample is better.

Hi,
RDBMS Event Generator Channel Rule Definition
When you are creating channel rule definitions in the WebLogic Integration Administration Console, it is recommended that you do not use the Back button if you want to resubmit the details on a page.
You should always use the navigation links provided and create a new channel rule definition.
http://download.oracle.com/docs/cd/E13214_01/wli/docs85/deploy/cluster.html
http://download.oracle.com/docs/cd/E13214_01/wli/docs81/relnotes/relnotesLimit.html
http://otndnld.oracle.co.jp/document/products/owli/docs10gr3/pdf/deploy.pdf
This problem has been seen in the past when defining the channel rule for an RDBMS Event Generator if schema name was specified with the incorrect case (i.e. lowercase when it should have been uppercase or vice versa). To that end, it is suggested to change the case of the schema when creating the channel rule

Problem using type 4 driver for SQL Server 2000

Hi..
I'm getting the following error message when i attempt to connect to SQL Server 2000:
"Cannot open user default database. Using master database instead"
I am passing the proper connection url and the user name and the password.However,my application does not connect to the SQL Server.I have tried using JTurbo and Weblogic drivers.
All tables in this database have been imported using DTS and hence have "dbo" as their owner.I do not have administrator privileges on the db server.
Is there a workaround to this problem by changing some settings for ownership of the db objects?
I have already tried using :
EXEC sp_changedbowner <username>
for databases where I am not a user and it still doesn't work for these as well.
Thanks,
Jay.

It might be in your DSN. Give that a check, it could be that the DSN has a default db selected and also a userID/Pwd that's incorrect for that db. Just thinking out loud.

Problem using CORBA clients with RMI/EJB servers..!!!???

Hi,
I have a question on using EJB / or RMI servers with CORBA clients using
RMI-IIOP transport, which in theory should work, but in practice has few
glitches.
Basically, I have implemented a very simple server, StockTreader, which
looks up for a symbol and returns a 'Stock' object. In the first example, I
simplified the 'Stock' object to be a mere java.lang.String, so that lookup
would simply return the 'synbol'.
Then I have implemented the above, as an RMI-IIOP server (case 1) and a
CORBA server (case 2) with respective clients, and the pair of
client-servers work fine as long as they are CORBA-to-CORBA and RMI-to-RMI.
But the problem arises when I tried using the RMI server (via IIOP) with the
CORBA client, when the client tries to narrow the object ref obtained from
the naming service into the CORBA idl defined type (StockTrader) it ends up
with a class cast exception.
This is what I did to achieve the above results:
[1] Define an RMI interface StockTrader.java (extending java.rmi.Remote)
with the method,
public String lookup( String symbol) throws RMIException;
[2] Implement the StorckTrader interface (on a PortableRemoteObject derived
class, to make it IIOP compliant), and then the server to register the stock
trader with COS Naming service as follows:
String homeName =....
StockTraderImpl trader =new StockTraderImpl();
System.out.println("binding obj <" homeName ">...");
java.util.Hashtable ht =new java.util.Hashtable();
ht.put("java.naming.factory.initial", args[2]);
ht.put("java.naming.provider.url", args[3]);
Context ctx =new InitialContext(ht);
ctx.rebind(homeName, trader);
[3] Generate the RMI-IIOP skeletons for the Implementation class,
rmic -iiop stock.StockTraderImpl
[4] generate the IDL for the RMI interface,
rmic -idl stock.StockTraderImpl
[5] Generate IDL stubs for the CORBA client,
idlj -v -fclient -emitAll StockTraderImpl.idl
[6] Write the client to use the IDL-defined stock trader,
String serverName =args[0];
String symList =args[1];
StockClient client =new StockClient();
System.out.println("init orb...");
ORB orb =ORB.init(args, null);
System.out.println("resolve init name service...");
org.omg.CORBA.Object objRef
=orb.resolve_initial_references("NameService");
NamingContext naming =NamingContextHelper.narrow(objRef);
... define a naming component etc...
org.omg.CORBA.Object obj =naming.resolve(...);
System.out.println("narrow objRef: " obj.getClass() ": " +obj);
StockTrader trader =StockTraderHelper.narrow(obj);
[7] Compile all the classes using Java 1.2.2
[8] start tnameserv (naming service), then the server to register the RMI
server obj
[9] Run the CORBA client, passing it the COSNaming service ref name (with
which the server obj is registered)
The CORBA client successfully finds the server obj ref in the naming
service, the operation StockTraderHelper.narrow() fails in the segment
below, with a class cast exception:
org.omg.CORBA.Object obj =naming.resolve(...);
StockTrader trader =StockTraderHelper.narrow(obj);
The <obj> returned by naming service turns out to be of the type;
class com.sun.rmi.iiop.CDRInputStream$1
This is of the same type when stock trader object is registered in a CORBA
server (as opposed to an RMI server), but works correctly with no casting
excpetions..
Any ideas / hints very welcome.

On the contrary... all that is being said is that we needed to provide clearer examples/documentation in the 5.1.0 release. There will be no difference between the product as found in the service pack and the product found in the 5.1.1. That is, the only substantive will be that 5.1.1 will also
include the examples.

With reference to your and other messages, it appears that one should not
expect that WLS RMI-IIOP will work in a complex real-life system, at least
not now. In other words, support for real-life CORBA clients is not an
option in the current release of WLS.

We currently publish an IDL example, even though the IDL programmingmodel in Java is completely non-functional, in anticipation of the support
needs for uses who need to use IDL to talk to the Weblogic server,
generically. This example illustrates the simplest connectivity; it does not
address how
to integrate CORBA and EJB, a broad topic, fraught with peril, imo. I'llnote in passing that, to my knowledge, none of the other vendors attempt
this topic either, a point which is telling if all the less happy to hear.
For the record then, what is missing from our distribution wrt RMI-IIOPare a RMI-IIOP example, an EJB-IIOP example, an EJB-C++. In this you are
correct; better examples are forth coming.
Still, I would not call our RMI-IIOP implementation fragile. I would saythat customers have an understandably hard time accepting that the IDL
programming model is busted; busted in the sense that there are no C++
libraries to support the EJB model, and busted in the sense that there is
simply no
support in Java for an IDL interface to an EJB. Weblogic has nothing to doit being busted, although we are trying to help our customers deal with it
in productive ways.
For the moment, what there is is a RMI (over IIOP) programming model, aninherently Java to Java programming model, and true to that, we accept and
dispatch IIOP request into RMI server objects. The way I look at it is this:
it's just a protocol, like HTTP, or JRMP; it's not IDL and it has
practically nothing to do with CORBA.

Eduardo,
Can you give us more details about the comment below:
I fear that as soon as the call to narrow succeeds, the remainingapplication will fail to work correctly because it is too difficult ot
use an idl client in java to work.It seems to me that Weblogic's RMI-IIOP is a very fragile
implementation. We
don't need a "HelloWorld" example, we need a concrete serious example(fully
tested and seriously documented) that works so that we can get a betteridea
on how to integrate CORBA and EJB.

Please post request to the news group...
As I said, you must separate the idl related classes (class files and
java
files) from the rmi classes... in the rmic step, you must set a newtarget
(as you did), emit the java files into that directory (it's not clearyou
did this), then remove all the rmi class files from the class path... ifyou
need to compile more classes at that point, copy the java files to theidl
directly is you must, but you can not share the types in any way.
I fear that as soon as the call to narrow succeeds, the remainingapplication will fail to work correctly because it is too difficult otuse
an idl client in java to work.

Hi Eduardo,
Thanks for the help. That is the way I compiled my CORBA client, by
separating the IDL-generated stubs from the RMI ones, but still I
get a
CORBA.BAD_PARAM upon narrowing the client proxy to the interfacetype.
Here's what I did;
+ Define the RMI interfaces, in this case a StockTrader interface.
+ Implement RMI interface by extendingjavax.rmi.PortableRemoteObject
making
it IIOP compliant
+ Implemnnt an RMI server, and compile using JDK1.2.2
+ use the RMI implementation to generate CORBA idl, using RMI-IIOPplugin
utility rmic;
rmic -idl -noValueMethods -always -d idl stock.StockTraderImpl
+ generate Java mappings to the IDL generated above, using RMI-IIOPplugin
util,
idlj -v -fclient -emitAll -tf src stocks\StockTrader.idl
This creates source for the package stock and also
org.omg.CORBA.*
package, presumably IIOP type marshalling
+ compile all classes generated above using JDK1.2.2
+ Implement client (CORBA) using the classes generated above, NOTthe
RMI
proxies.
+ start RMI server, with stockTrader server obj
+ start tnameserv
+ start CORBA client
Then the client errors when trying to narrow the obj ref from the
naming
service, into the CORBA IDL defined interface using,
org.omg.CORBA.Object obj =naming.resolve(nn);
StockTrader trader =StockTraderHelper.narrow(obj); // THIS
ERRORS..!!!
throwing a CORBA.BAD_PARAM exception.
any ideas..?
Thanks in advance,

Please see the post on june 26, re Errors compiling... somewherein
there,
I suspect, you are referring to the rmi class file when you are
obliged
to
completely segregate these from the idl class files.

Hi,
I have a question on using EJB / or RMI servers with CORBA
clients
using
RMI-IIOP transport, which in theory should work, but in practice
has
few
glitches.
Basically, I have implemented a very simple server,
StockTreader,
which
looks up for a symbol and returns a 'Stock' object. In the firstexample, I
simplified the 'Stock' object to be a mere java.lang.String, so
that
lookup
would simply return the 'synbol'.
Then I have implemented the above, as an RMI-IIOP server (case
1)
and a
CORBA server (case 2) with respective clients, and the pair of
client-servers work fine as long as they are CORBA-to-CORBA andRMI-to-RMI.
But the problem arises when I tried using the RMI server (via
IIOP)
with
the
CORBA client, when the client tries to narrow the object ref
obtained
from
the naming service into the CORBA idl defined type (StockTrader)
it
ends
up
with a class cast exception.
This is what I did to achieve the above results:
[1] Define an RMI interface StockTrader.java (extending
java.rmi.Remote)
with the method,
public String lookup( String symbol) throws RMIException;
[2] Implement the StorckTrader interface (on a
PortableRemoteObject
derived
class, to make it IIOP compliant), and then the server to
register
the
stock
trader with COS Naming service as follows:
String homeName =....
StockTraderImpl trader =new StockTraderImpl();
System.out.println("binding obj <" homeName ">...");
java.util.Hashtable ht =new java.util.Hashtable();
ht.put("java.naming.factory.initial", args[2]);
ht.put("java.naming.provider.url", args[3]);
Context ctx =new InitialContext(ht);
ctx.rebind(homeName, trader);
[3] Generate the RMI-IIOP skeletons for the Implementation
class,
rmic -iiop stock.StockTraderImpl
[4] generate the IDL for the RMI interface,
rmic -idl stock.StockTraderImpl
[5] Generate IDL stubs for the CORBA client,
idlj -v -fclient -emitAll StockTraderImpl.idl
[6] Write the client to use the IDL-defined stock trader,
String serverName =args[0];
String symList =args[1];
StockClient client =new StockClient();
System.out.println("init orb...");
ORB orb =ORB.init(args, null);
System.out.println("resolve init name service...");
org.omg.CORBA.Object objRef
=orb.resolve_initial_references("NameService");
NamingContext naming=NamingContextHelper.narrow(objRef);
... define a naming component etc...
org.omg.CORBA.Object obj =naming.resolve(...);
System.out.println("narrow objRef: " obj.getClass() ":"
+obj);
StockTrader trader =StockTraderHelper.narrow(obj);
[7] Compile all the classes using Java 1.2.2
[8] start tnameserv (naming service), then the server to
register
the
RMI
server obj
[9] Run the CORBA client, passing it the COSNaming service ref
name
(with
which the server obj is registered)
The CORBA client successfully finds the server obj ref in the
naming
service, the operation StockTraderHelper.narrow() fails in thesegment
below, with a class cast exception:
org.omg.CORBA.Object obj =naming.resolve(...);
StockTrader trader =StockTraderHelper.narrow(obj);
The <obj> returned by naming service turns out to be of the
type;
class com.sun.rmi.iiop.CDRInputStream$1
This is of the same type when stock trader object is registeredin a
CORBA
server (as opposed to an RMI server), but works correctly with
no
casting
excpetions..
Any ideas / hints very welcome.

Problems using Oracle Directory

Hi all
I have the following problem using 9i: I would like to use oracle internet directory to register my db's. I am currently reading the online handbooks and found a section that says to start the directory by using the 'oidmon' and 'oidctl' commands. The problem is that I cannot find these tools anywhere on the server, altough i am pretty sure i intalled anything important. is this a separate product? I thought it was included in 9i 9.2?
Anyone?
Cheers,
Michael

Hi.
Hmm, your shared lib path appears to be ok. What version of Solaris are you running? Also what JDK version are you using (I'll assume you are using the one that installed with WLS)?
You might also try posting this to the weblogic.developer.interest.jdbc newsgroup.
Thanks,
Michael

Using myfaces tomahawk inputFileUpload componet

I am using myfaces tomahawk inputFileUpload componet for the following requirement
1. I need to upload images to my user profile page.
2. Resize the image to fit my desired image size to be shown on the page
Promblems
1. The file i upload is done fine and images also show but
the image is stored or refrenced to the local machine , so if i delete or change file location the image dosent show.
what i need is to store the images in a seperate folder on the server or any other place and image should point to that location.
2. Now the image uploaded displayed using jsf's
<h:graphicImage url="fileupload_showimg.faces"/>component where "fileupload_showimg.faces"
is a jsp page containing the following code
which is a scriplet
<%@ page import="java.io.File,
                 java.io.InputStream,
                 java.io.FileInputStream,
                 java.io.OutputStream"%><%@ page session="false" %><%
    String contentType = (String)application.getAttribute("fileType");
    String fileName = (String)application.getAttribute("fileName");
    String allowCache = request.getParameter("allowCache");
    String openDirectly = request.getParameter("openDirectly");
    if(allowCache == null || allowCache.equalsIgnoreCase("false"))
        response.setHeader("pragma", "no-cache");
        response.setHeader("Cache-control", "no-cache, no-store, must-revalidate");
        response.setHeader("Expires", "01 Apr 1995 01:10:10 GMT");
    if(contentType!=null)
        response.setContentType(contentType);
    if(fileName != null)
        fileName = fileName.substring(fileName.lastIndexOf('\\')+1);
        fileName = fileName.substring(fileName.lastIndexOf('/')+1);
        StringBuffer contentDisposition = new StringBuffer();
        if(openDirectly==null || openDirectly.equalsIgnoreCase("false"))
            contentDisposition.append("attachment;");
        contentDisposition.append("filename=\"");
        contentDisposition.append(fileName);
        contentDisposition.append("\"");
        response.setHeader ("Content-Disposition", contentDisposition.toString());
    byte[] bytes = (byte[])application.getAttribute("fileSizeBytes");
    if (bytes != null)
         response.getOutputStream().write(bytes);
%>works fine but the image shown in its original size most of the time very large.
I tried to fix the image size by changing the code to
<h:graphicImage url="fileupload_showimg.faces" width="300" height="500"/>But now the image is shown is deformed
i need it to be fixed in size and not deformed

me again I think the first part of the problem is been solved now
the 2nd problem is still there hope i can fix that also
