K.
Granted I am not distributing XML so I set the content type to
"application/zip", but the trick to get the SAVE AS dialog for me was the
Content-Dispostion header. My code (in a servlet) goes something like
this...
response.setContentType("application/zip");
response.setContentLength(len);
response.setHeader("Content-Disposition","attachment;filename=\"somename.ext
\" ");
Works most of the time except certain buggy versions of IE 5.5 for which
a patch is available from Microsoft (so I believe).
Hope this helps?

RE: Security between applications?
Securing datasources is no match for Weblogic. I do not know how Orion handles this. /korre -Original Message- From: Cliff Rowley [mailto:[EMAIL PROTECTED]] Sent: den 13 februari 2001 20:09 To: Orion-Interest Subject: Security between applications? Greetings, We are currently evaluating the various J2EE solutions available for a venture that we hope to deliver to the world in a few months. Whilst reading the documentation for each, I dont appear to be able to configure Orion to suit the way the project will work. In order for our application to be of any use, we need to be able to implement a fair amount of security, since JSP pages may be at the mercy of people who are not us. Basically the application will provide a farm of hosts on which we will be offering certain services. Each application needs to have a data source that it, and only it has access to. The current problem as I see it is that if I define a connection in data-sources.xml, then every web application deployed on the server or cluster of servers has access to it. We need some way of securing that while still being able to use EJB in all its glory. We need to be able to offer the opportunity of creating and editing content without compromising the security of other applications on the system. Could anyone give us some tips and pointers on this? Thanks Cliff Rowley

RE: Any news from Orion yet??
"Weblogic (and the high priced products like Websphere) are great..." Speaking as someone who has done development using Websphere (3.0 & 3.02): It sucks! Don't use it for anything but JSP or servlets. It has so many flaws that I don't even want to get in to them!! /korre -Original Message- From: Kemp Randy-W18971 To: Orion-Interest Sent: 2001-02-12 13:58 Subject: RE: Any news from Orion yet?? Weblogic (and the high priced products like Websphere) are great, if you want to pay the price. They come with nice tools like front end gui's, good documentation, paid support, etc. But if you look for the opinions of developers who have used these products, and compared them to Orion, jboss, etc., they would say the EJB capacies are no better then the other high priced products. In order of ranking, here's how I look at the other products. 1 Orion -- This product is ready now, but I haven't seen anyone from this list run a Sears store on it. 2. Jboss (www.jboss.org) -- The founders are very bright, have five hundred developers on the projects, have EJB heavies contributing to the list, and it's a very easy to use product. Personally, even though it is ready for production now, I would wait for it to mature a bit more. It's like a fine wine -- drink it now, and it is OK, or allow it to age a bit then drink it (like jboss 3.0 final). 3. Openejb (www.openejb.org) - this project has a very bright and well known person heading it, and it is slated to be intergrated with Tomcat and Apache. It has yet to prove itself, as it is not yet ready for production release. But it has good future promise. 4. Jonas (www.evidian.com/jonas) - This is a good product, but it is not as advanced as the other two open source products and I don't think they have as many people behind them. 5. Enhydra enterprise (www.enhydra.org). If you like the enhydra application server, this product has potential. But it is not production ready yet and it intergrates with the jonas server. In summary, Orion is here now but can it run Sears? Jboss is ready but I would let it mature a bit more for production environments. Openejb and Enhydra have great potential, but they are not ready yet and have to prove themselves. Jonas is OK but I prefer the other open source alternatives. -Original Message- From: Anthony W.

RE: HTTPS from Orion Java Bean
Are you using the exact same JDK in both cases? With the exact same
libraries?
We had some trouble with Weblogic always using their implementation of ssl
and used the following to override it:
if(url.indexOf("https")!=-1){
URLStreamHandler h =(URLStreamHandler) new
com.sun.net.ssl.internal.www.protocol.https.Handler();
sparBankenURL = new URL(null,url,h);
}
plus of course:
the jsse.jar in the classpath and associated entries in the
$JAVA_HOME/jre/lib/security/java.security file.
I am not saying you should do it like this but it is nicer as it throws
"ClassNotFoundExceptions" instead of "no implementation found".

Sounds to me like you are getting a different URLConnection subclass in

RE: Servlet loading twice if init() not finished?
There should be only one servlet instance per VM according to
Servlet spec 2.2 chapter 3.2.
Unless of course the servlet is implementing "SingleThreadModel".

Subject: Re: Servlet loading twice if init() not finished?
I believe that is perfectly normal behavior. Init() is called whenever a
servlet
instance is created, and they may be created at any time and in any
number (unless
you specify a limit in your servlet engine, or you use the single
threaded model
for your servlet, which I do not recommend for obvious reasons). This is
why your
servlet must be written for a multi-threaded environment.
The only workaround I can think of, if you can not redesign your code,
is to use
a Singleton to get the loading done, and make the Singleton
synchronized.

Why not use something like:

I have created a small client software which connects to EJB-services
running on Orion, of course.
My program has a GUI "launcher" from which users can start client
objects. These objects use InitialContext to deliver user/password
information
to EJB-services.
Everything works fine until user gives wrong username/passwd ...
Now since InitialContext is permanent threre is no way to change it
anymore unless user restarts the program, which is lame.
Code:
Runtime r = Runtime.getRuntime();
Process p = r.exec(" java myClass ");
Works but is awfully slow. Any insights?

RE: ejb deployment problem
That is because in JBuilder you deploy your beans to IAS. You specify a Datasource name. You have to specify a different DataSourc name for Orion too. That can not be done inside of JBuilder. For Orion: 1 Open /application-deployments//orion-application.x ml 2 Add an attribute default-data-source="" to the element 3 Remove any ejb deployment descriptors below this directory (orion-ejb-jar. xml) 4 Start Orion. Orion should now deploy your ejbs again. 5 Check in an orion-ejb-jar.xml file in any element for an attribute data-source. Hopefully it should now use your Data Source. /korre -Original Message- From: ahfei To: Orion-Interest Sent: 2001-01-07 18:00 Subject: ejb deployment problem hello, i'm developing ejb using jbuilder4.The EJBs work well in inprise app server. when i deploy it to orion,it works too. but i found the datasource that i specified doesn't be used,orion uses a default datasource (HSQL) service my EJBs.WHY ? can somebody help me? thanks in advance. ahfei [EMAIL PROTECTED]
