Weblogic 10.3, Spring, and Fastswap

I am working on a large web application using Weblogic and Spring Framework. When fast swap is disabled, I can publish the application using OEPE, but when fast swap is enabled in weblogic.xml, it gives the following error:
<Mar 23, 2009 4:33:40 PM PDT> <Warning> <Deployer> <BEA-149078> <Stack trace for message 149004

My question is, where is this BEA version of class coming from? Is Weblogic renaming MyClass in memory? What's the purpose of doing that?
Thanks!

We have seen similar classloading problems when enabeling FastSwap, we found no workaround for these issues.
Last time i tried to enable it I got some wierd local/remote interface problems with EJB, it said something like method beaInvoke not defined in Bean class.

Integration of Weblogic Server 10.3 and Spring 2.5

Hello.
I read that Weblogic 10.3 supports a Spring extension which allows Web component creation using Spring framework.
http://e-docs.bea.com/wls/docs103/programming/spring.html#wp1079570
Has anybody tried this?
In particuar, documentation says:
"Enable the Spring extension by setting the <component-factory-class-name> element to org.springframework.jee.interfaces.SpringComponentFactory. This element exists in EJB, Web, and application descriptors."
Which descriptor for a Web application? web.xml? weblogic.xml? I tried both but I received validation errors.
Can anyone explain this part a little better?
Regards
Davide

I am fed up with Spring and Apple passing me off to one another and neither will fix the problem. I am unable to receive a connection on my phone.

I am fed up with Spring and Apple passing me off to one another and neither will fix the problem. I am unable to receive a connection on my phone.
The internet goes out and I have to reset network setting each and every time. This is only a temporary solution which by the time I release the line with Spring or leave the apple store the issue is back. Sprint indicates that it is a know issue with the Iphone 5 and apple says it is a network issue as Sprint's network is not up to par with the Iphone and can not meet the expectations on the Iphone 5.
I have attached a few picture, as you can see it clearly says I have 5 bars and 3g available but I have no connections what so ever.
This issue affects all data and so I can not send or receive picture messages, use apps, or access the internet. The data goes in and out intermittently and it seems the phone chooses what I can and can't do.
For example I can watch Youtube or Vevo videos but I can not access Facebook or Instagram.
Is anyone else having this issue?
I will soon loose my patience....
I have reset my phone three time and have reset network and other setting mutltiple times.

Transfer Object in JSF, Spring, and Hibernate

The application on which I am working deploys the JavaServer Faces, Spring and Hibernate frameworks.
We are going to use the "transfer object" to move data between J2EE tiers from the front end to the back end and vice versa. In addition, data "types" may need to be converted --
At the front end, the "type" of the data that are entered by users may not match that in the database table. For example, checkboxes may be marked or left blank by users. The "type" of the checkboxes is "boolean" in the JSF backing bean. However, we have either "Y" or "N" for the corresponding field in the database table.
The JSF backing bean holds data as well as controller functionality. Of course, the transfer object holds data only.
With regard to class properties, Is the transfer object an exact copy of the JSF backing bean? And at which tier the data are converted to match their correspoding "types" in the database tables?
We also have the "data objects" which are exact representation of database tables.
Thanks for your advices.

Small example: you can decide in the business layer
whether to convert it to boolean or Boolean (which
has a 3rd state: null).But it all goes back to your data model. If your data model supports null for that property, then of course boolean is a poor choice. If that case one could use Boolean. None of this has anything to do with re-usability, which was your objection.
I think the re-usability question goes back to the data model as well. Suppose your data model says this property is boolean valued. However if your database does not support booleans natively, then you need to map the value for storage in the database. But that is the data persistence layers problem.
OTOH, suppose your data model says that this property may be 'Y' or 'N'. Then the Java class represent the business object should not have a boolean property, we should make it match the data model.
However, I think that most cases where people are storing 'Y' or 'N' in a field in the database fall into the first case, where the data model is a boolean and they are working around limitations in the database. There is no reason in that case to perpetuate the same limitations in the Java code.

Configuration problem in Weblogic 8.1.1 and 8.1.3

We have a problem when we hitting instrumented axis services in weblogic 8.1.1 and 8.1.3.
1.First we create a domain its use for only axis services.
2.We set the class path according to my project.
3.I start the server and deploy my axis services.its deploying nicely.
4.After that used my project and configure the services to getting log file purpose.
5.After instrument/configuration the service,I restart the server that time the service is redeploy and create the temporary file in .wlnotdelete directory our jar file put inside in this folder extract/myserver_calc1_calc1.This is my deploying service place.
6.But its not happening in this version of weblogic in that we redeploy the same services its works fine and getting log files.
7.when i redploy the same service that time only its working fine.
8.But i don't want to redploy the service. I want only restart time its happen that's only correct.
9.This problem is only happening in weblogic 8.1.1 and 8.1.3 its not happening in weblogic 7.5 and 8.1.4 is working fine and getting log files.
10.can any one give me a solution to rectify this problem in Weblogic 8.1.1 and 8.1.3.

I don't know about that, but I am using MyFaces and tomahawk with WLS8.1 sp5 jdk1.4.2_05 and it works fine.
I do remember getting such an error when I moved from Sun RI to MyFaces and all I can recall is that it was a commons library mismatch problem or some classpath problem...

How is the processing speed while using struts,spring,and JSF framework

Hi friends,
As per earlier technology like Servlets,I mean that there would have much more performance speed than other new technologies like JSP,struts,spring and hibernate framework.Because,in new technologies,flow of processings implicitly via MVC2 basis will probably much more time than older one.
Total goal is only for attaining MVC2 or any other purpose?
Please clarify my doubt?
With Regards,
Stalin.G

Home grown applications have a problem in that as more and more features are added, it becomes increasingly impossible to maintain the application and enhance it. This is especially true when the original programmers leave the company. A framework provides a standard design approach that other programmers can hopefully more easily pick up.
A lot of work has gone into creating these frameworks and they have been used in web sites that have millions of hits from users per day. They have high preformance. Of course, programmers can still write bad code in them that slows down the system. I believe anyone using these frameworks should study them well before using them (such as reading books on them).

How to get weblogic logged in username and password in an MBEAN

Hi,
I have an MBEAN deployed under AdminServer. Want to establish a remote connection to credential Store MBean in base_domain using t3 protocol from this MBean, Which requires weblogic username password, port and host.
What is the best way to get username and password,in an MBEans deployed in AdminServer at runtime.
Thanks for your help in advance

I don't think there is any way to get the password. What type of credential store is this and is it in the same domain?

Weblogic 10gR3 standard edition and enterprise edition

Difference between weblogic 10gR3 standard edition and enterprise edition ??

WebLogic Server software is the same in all of the various download distributions available that vary on platform and 32/64 bit architecture. However, which features are licensed for use vary by the edition customers license, which is covered here:
http://download.oracle.com/docs/cd/E14571_01/doc.1111/e14860/products.htm#i1041725
That link is for WLS 11g, but it applies generally to WLS 10.3.0 as well.

Starting the WebLogic server, the NodeManager and the ManagedWebLogicServer (oam_server1)

DB Tier - 12.0.1 - Linux x86_64 SLES11-SP2
Application Tier - Linux x86_64 SLES11-SP2
Fusion MiddleWare - 11.1.2.2
I have installed all components for the OAM server and have gotten it up and running following docs located at
http://docs.oracle.com/cd/E40329_01/install.1112/e49521/install.htm#BABLBHBC
When starting the stack, I find that I have to open three separate xTerm windows for starting the WebLogic server, the NodeManager and the ManagedWebLogicServer (oam_server1). These windows have to be kept open until you decide to stop the servers.
Is there anyway to start the servers with 'nohup' so that they are running in the background? If someone inadvertently kills the VNC sessions, that will mean that the services that were started in that particular vnc session will also be killed.
There has to be another way around this.....and I'm looking to see if anyone on here can help with suggestions.
Thanks

Weblogic server 9.2 and SSL server certificate for the wrong site

I turned on SSL service for a weblogic 9.2 server and later on changed the hostname of the machine that weblogic was running on. So the hostname that my SSL server certificate was issued to has now became an invalid hostname. But my weblogic server continues to run SSL service without any exception. I can still access my web applications thru the SSL port (except of course I get a warning for the server certificate every time that it is for the "wrong site"). My question is this: should weblogic 9.2 verify the hostname in the server certificate and stop SSL service if the certificate is for the wrong site? Or is verifying the certificate strictly the job of the browser? Just want to make sure there is nothing wrong with my SSL configuration. Thanks.

So you are saying that something is wrong with my weblogic 9.2 ssl configuration? And that given a server certificate issued to a different hostname, my weblogic server should NOT be servicing ssl request and/or it should throw some sort of exception during startup? Thanks for clarifying.

Multiple timezones on weblogic 10.3.6 and forms 11.1.1.6

Hi
I have installed weblogic 10.3.6 and forms 11.1.1.6. I am trying to setup different forms environments with different time zones within the same installation of forms 11.1.1.6.
I have 2 environments testau and testnz.
testnz.env has a parameter name = time_zone and value = Pacific/Auckland.
testau.env is defaulted as the server timezone is set to Australian time.
The testnz and testau environments are all the same within the forms(Australian time), how can I set the testnz to New Zealand time?
Thanks

Weblogic portal external authentication and authorization

In our project we are using Weblogic portal 10.3 and Oracle 11g as back end. While creating the domain, I have specifed Oracle as back end. All the portal relevant schemas are created in Oracle database. For our application, We have created a specific schema. In a project specific schema, we have user table which containing fields like user name, password, email and other relevant fields. How to configure in weblogic to access this table for authentication instead of the user table in portal schema? As well as I need to know, in a admin console if a new user is created then the details will be stored in a portal schema table or in a project schema user table? Ultimately, I want to configure the project specific table to store the user details when the user created via admin console.
Need this urgently.

Hi Rajesh
Basically you need Custom Authenticator to store and authenticate all your users from your own specific DB Tables (that has user information). For this you need to develop Custom Authenticator. Please note that this has nothing to do with the Portal. This is core weblogic security stuff. I compiled some links for you. Incase if you have Oracle Support, open a ticket with them Oracle support do have a fully working sample custom RDBMS Authenticator that stores and authenticates Users from specific set of custom Tables. They will send you right away. I hope someone in these forums may have this sample also in their personal blogs/forums.
And, Yes, you can force your Custom Authenticator to be the default one and to store the users when you create the users in Admin Console. Basically when you create the users you should see the option like to create the users in which Authentication Provider like that.

I know of no reason that SP3 should be required with Cocoon. In general
regardless of the SP you may need to have Cocoon classes first as you may
bet XML parser conflicts.

Regarding Weblogic Server 5.1 and Jview.

I have an applikation running on a Weblogic server 5.1 and have to access COM Components -
I used MS J++ to wrap the COM components and started the server with jview. That work just fine
as long as I dont include the rt.jar from the jdk1.3 library in the classpath. Why is that? I know
Weblogic Server is not sertified for using jdk1.3 on windows 2000, but is that the reason?
The error according according to Microsoft documentation is that there are dll's missing in the
system path,but it works just fine without rt.jar ...
If someone has encountered the same problem please respond ...
The error I get is :
The WebLogic Server did not start up properly.
Exception raised: java.lang.UnsatisfiedLinkError: java/security/AccessController

I think my Q is not clear. I shall explain how the application works. I am having application based on Swings and that is a website building program. User has options like ading an image into their site with an element called 'Image' available as part of the system. Then user can either select an image from the picture gallery provided or can upload his own image.
Now, if the user is uploading a picture that has space in name ( we use a servlet program to upload the image into user directory), it will get uploaded. But when the swing program tries to paint the image in the Image element ( It is essentially a JLabel ), the program is sending a request to the WL server. Since the URL contains space in name, server returns error. Even if do URL Encoding, it will add %20 in the URL and still WL will report error saying that file not found. It seems that WL is unable to process requests that has space in the URL.
If any one has any solution to this, please help..
