I have a production Weblogic 7.0 server running in Solaris with a Sun JVM 1.3.1. I have to do an outage, and I wanted to get a Heap Dump from the JVM to look for any memory leak the application could be producing. Is there any trick to get the Heap Dump. It doesn't matter if the JVM crash, as I will be doing this during the outage.

Thanks.

Thanks a lot, Mr. Ko Ko.
Hi all,
Is the SCWCD Exam Study Kit of Hanumant useful for the next version of the SCWCD Exam? Can I use it, and complete the study with the new specifications of servlets and jsp?
Thanks.

Hi all,
Somebody knows what will be present in the next version of the SCWCD exam? It will be only about Serlvet 2.4 and JSP 2.0? Do you know if something about JSF will be included?
Another question, JSF will be part of the J2EE specification (next after 1.4 for instance)?
Thanks in advance.

Yes,
I saw this two classes but I could not find the way to do this.

Hi everybody,
I need to set up Weblogic Server as a Linux Service so it starts at Linux start up and I can start and stop it through service command.
And for Solaris, how can I do the same thing?
Thanks a lot.

Why JDK does not have an AbsoluteLayout to be easier the GUI development? Why I have to learn about different type of layouts, I think this makes more difficult the GUI development.
Thanks.

Hi all,
I'm in a project using WL 6.1 sp4 and we are thinking in to migrate to WL 7.0. We are using JSP and EJB. There are many differences between both version that can make the migration dificult.
Thanks in advance.

Hi all,
In using WL 6.1 SP4 and I have a method in one facade session bean (with CMT and Required transaction level) that receives a Collection of InvoiceVO to insert them in the database. The max-beans-in-cache property of the InvoiceEJB entity bean is set in 100. When I pass a Collection with more than 100 invoices, the server insert the firsts 100 invoices and throws an weblogic.ejb20.cache.CacheFullException.
Why Weblogic has this behavior, and how can I tell it to change this behavior.
The following is the code of the facade method:
public void loadInvoices(Collection colInv)throws FacadeException {
 try{
   Iterator iterRec=colRec.iterator();
   while(iterRec.hasNext)){
     InvoiceVO invVO=(InvoiceVO)iterRec.next();
     getInvoiceLocalHome().create( //entity bean
       invVO.getInvNumber(),
       invVO.getInvCustomerName(),
       invVO.getInvDate(),
       invVO.getInvAmount(),
       ......,
       ......);
}
 }catch(Exception e){
   throw new FacadeException();
 }
}

Hello,
I have a large process triggered from a JSP page, that at the finish of it shows another JSP page with the results. How can I show a processing page or even better a progress bar during the process.
Thanks a lot.

Hi all,
Several books about SCWCD have been released at this moment. I know one from Manning and the other from Wrox. Which book do you recommend?
Thanks.
Cristian.
Yeah, but, usually the name of .class in nested classes is parent$child.class
In this case the name inside the .java file (source code) is _cls$Base and the name of the .class file is $Base.class
Here it's the source code resulting after decompile a $Base.class file:
class _cls$Base{
..............
..............
..............
}
Thanks.

Hi all,
I have a class which .class name is $clase.class and by decompiling it, I saw that the name in the source code was _cls$clase. Why the names are different. Which is the trick?
Thanks.
