Simple Java Doubts
Question 1: How does an elementary Singleton pattern based Object behave in a multi-threaded environment? What is this phenomenon called? How do you make such a Singleton Object thread safe? Question 2: What are the two methods typically employed to notify remote clients distributed over the Internet of events that take place on a central server? Like changes in the price of options, market depth, or an order execution? What are the relative advantages/disadvantages of each of these strategies?

Re: Any news from Orion yet??
Hi kevin, As far as i have known WL5.1 or , there is no concept of ear files, does 6.0 include that. Doesn't the J2EE mandate (I am not sure!) the use of EAR = WAR + JAR + CAR(or JAR)? To deploy the JPS1.1.1 on Orion, it is a piece of cake, while deploying on WLS, i have to unpack the EAR files and dis-integrate them which is contrary to the essence of packaging the ear files, Even meddling with the ugly weblogic.properties frustrates one and all.

Re: orion server works with jdk 1.3???
Sorry for a very late reply, Kemp seems to have a very lengthy, painful solution while the actual workaround is just too simple. Somebody mentioned that the problem is in the registry. Yes! He got it right. Just type REGEDIT and modify the current version as shown in the attachement. Look at the attachment picture i have sent.

Re: Problem using JavaMail with Orion
If you are using jdk1.3 then push the javamail.jar or mail.jar whatever it
is {jar relevant to javamail] into
jre/lib/ext folder...The problem should not arise...

JSP-Compiled Servlets ??
hi all, Weknow that JSP are compiled into servlets. In Jrun, I canview the equivalent servlet source code for the JSP. ButOrion doesnt seem to provide the source as well as class file. All it creates is a binary jsp.Cache file. But my job is to get into the code and see how the servlet is getting written and compare with servlets generated thru other jsp-engines. What do i do?

Re: JSP cannot find Bean Class
If this is using orion, then i have my own doubts as to where the .ear file is located in coz the jsp-engine is unable to locate the bean. Becoz the orion jsp-engine finds the beans (just javabeans not EJB) when i keep it under WEB-INF/classes folder. So try placing the bean there and check Santosh - Original Message - From: Hauke Zühl [EMAIL PROTECTED] To: Orion-Interest [EMAIL PROTECTED] Sent: Tuesday, October 17, 2000 2:51 PM Subject: JSP cannot find Bean Class Hello folks, I have a strange problem: I wrote an BMP Enterprise Java bean (Mystuff.java, MystuffEJB.java and MystuffHome.java), compiled it and put it into a jar-file (which I later put into a .ear file). Later I wrote the component file MystuffBean.java and included the compiled file with useBean class="MystuffBean" into my JSP file, and finally put that stuff into a .war-file. After deploying the .ear file and calling the JSP with a browser, the JSP tells me that "Bean type 'MystuffBean' not found". So what might be wrong there? Regards, Hauke
Re:Orion slower than...
Hi Nate,
Do you have some figures to look at?
I mean, How much was the improvement in speed? What is the size of the
content file?
Did you try out with various content sizes?

We tried using Orion to host 2 servlets, one using compression one not -
the
one using compression was much faster than the one without it. I assume
this means that orion's JSP are not compressed.
Please repsond if this is an inaccurate statement
Thanks

You can do content encoding in jsp, I did it. Just make sure
that the page
does not access the implicit variable out at all (e.g do not
have blanks
outside scripts).
But I think that jsp is not the right tool to do that. The
JSP-Container
should do that for you.
The code is roughly:
%@page .%
response.setHeader("Content-Encoding", "gzip");
GZIPOutputStream gos = new
GZIPOutputStream(response.getOutputStream());
byte[] b = "html bla bla .../html".getBytes();
gos.write(b);
gos.close();

Does orion do this automatically ? caus eit doesn't seem to
