Hi,

I am adding the tree nodes dynamically in the prerender method of the backing bean to the JSF Tree. The nodes are getting added successfully but the icon is not visible.

The icons are visible for the nodes that are added to the JSF Tree using the netbeans editor. The following code is added the JSF tag of the tree node for which the icon is visible.

<f:facet name="image">
<webuijsf:image icon="TREE_DOCUMENT" id="image4"/>
</f:facet>

How we can add this facet to the tree node i am creating in the prerender method?

Can you please help me?

Hi,

In one of the application, the client browser access a JSP which will access the DB to generate more than 300 tables(each table with 10rows) in the response. The problem is that the client page is getting populated with the tables continuously and so the client processor utilization is 100% for some time.

I am thnking that this problem can be solved if we show some intermediate page that shows a progress bar or a gif image until the server response is completely generated in the server side.

Do you have any idea about how this can be done? Or please suggest me how we can rectify this problem?

Thanks!!!

Reflection is working fine if the Remoteinterface and RemoteHome class files
are packaged along with the Calling Servlet war file.

Will this technique work if we don't have Remoteinterface and RemoteHome class files in the claling servlet war?(I suppose it is not possible).

Please suggest the solution to acheive the same.

Thanks

Hi Anthony Graffeo,

Thanks for your reply.

It is working fine now by incorporating the logic given by you.

Is there any possibility to implement this requirement from EJB??
Is it possible to develop a generic client code to access arbitrary EJBs deployed in the application server. The user will deploy their own EJBs in the production environment along with a xml file which provides the complete info about EJB like JNDI name,LocalHome,LocalInterface etc.

But the Client Code should be Generic enough to narrow down any EJBHome(Client should not hardcode any specific Home Class in narrow() method). The client is a web component deployed in the same application server.

The application in which i am working in, has to invoke a perl script in the remote machine and get the results from a file written by it.

So, please suggest, how to implementt this in EJB module. Or alternatively can we have a web component in the server which will handle this requirement.
Hi,

Is there any restriction in using getRuntime().exec() within EJB to create a new process. Also, can we create threads from within EJB?

Hi,

I am working in a tier-1 company in India for almost 1.4 years. And i joined this compnay as a fresher. Our team is doing maintainance activities for a telecom product. Initally i was assigned a development job on CGI-PERL, which i have finished in 4 months after learning CGI-PERL from the scratch.

Then i was assigned a job on C++ which took nearly 3 months for me to complete. Then i was assigned a job on JAVA, which i liked very much since they have given the complete design and coding job to me. Meanwhile, i have completed SCJP in 1.5 and also SCWCD ceritifications.

And now the problem is they are again asking me to work in C++ for 6 months. I am feeling bad to work in a team where they are making me work in different languages for short intervels, so i cannot get full and complete knowledge in a language and the related technologies. Even i am thinking that it will not help me in building a better carrer in the future.

I have expressed my feelings clearly to my PM and PL, but they are not ready to releive me from their team for certain reasons. They are asking me to work in their team for at least next 7 months.

I am totally confused and slightly depressed now. Can any one suggest me what i can do now? Can i quit my job and join some other company where i can get a job in the interested areas???

Hi,

Is it possible to deploy an Entity bean with both the local and remote view?

If it is not possible, then why in J2EE RI deploytool, they have given option to select the classes for both the Remote and local Views for all the beans that are deployed??

Please clarify... And i have read in the sun website the following line:

"Although a bean can have both a local and a remote client view, typically a single enterprise bean provides only one of these two views. "

Hi,

I have cleared SCWCD Exam last Saturday with a score of 81%.

I have followed only HFSJ book for the exam preparation, and i
have preapred for nearly one and half months.

My perception about the exam is, if you get the concepts clearly from HFSJ book(you should learn the concepts practically by implementing everything ), you can get 80%(since i have got the same ).

To get more than that, definitely you should go through the Specifications completely(hope it is difficult to do this, since it is highly technical) or you should purchase some test preapration kits(hope they might have better questions for you to prepare for the exam).

I have taken nearly some 15 mock exams that are available free in the Internet including Java Ranch's mock exam. But really they are not much helpful, as the questions in the SUN exam are tougher than the questions in those exams.

But you can expect the questions in the Exam, in the same level of toughness, as it is in the HFSJ Book. I have taken the final mock exam in the book on the previous day of my Exam, and i have scored 79%.

Actually i was expecting some thing more on the real Exam, but i have got 81%, just 2% more than what i have got in my final Mock exam. So, you can very well judge yourself by taking the mock exam in the HFSJ book.

what about the value scriptless?
Congrats Anbu,

Really it is a good score.
Hi,

Is JSP a valid value for <body-content> sub-element of tag element in
tag library descriptor.

I have read somewhere that if you want to make your tag accept JSP as the value for the <body-content>, then you should not make an entry for the <body-content> sub-element under tag element. And the tag handler assumes it as JSP.

Even i have tried to use JSP as the value for the <body-content>, but the
container is showing me an error 'it is not a valid value'. But in HFSJ, no
information about this problem.

Please give me some info about this, if you know?
