stored procedures and entity beans
I'm in the position of trying to migrate towards a j2ee/ejb architecture from one where most of the access logic (and to an extent, business methods) were in stored PL/SQL procedures in an Oracle 8i database. To keep from having to "reinvent the wheel"s of the stored procedures (and making the transition easier), are there any existing patterns or methods for utilizing stored procedures but still using EJB's? Is the answer simply "use BMP, put the stored procedures in load/store"? is there any orion-specific trick of defining a _query but using a stored procedure instead (can orion fetch from out variables instead of resultset?

orion on unix

When I log in to unix as user 'orion' and try to start up the app server by typing java -jar orion.jar, I get a message "Error starting HTTP-Server : Permission denied". I can only startup orion if I log in as root user. This is not acceptable because I can't let everyone to have root access just for starting up the orion server.(Our project still in the development phase so we need to start and stop the server quite often) I am puzzle with this error because I have already set the owner of all the files under orion folder to be 'orion', and orion app server is using it's own http-server internally so it shouldn't has any permission problem. I think that orion app server might try to access some of the unix system file which must have root access, if this is the case can someone tell me which file it it?

Native user support
Hello, An article on dcb.sun.com (http://dcb.sun.com/practices/profiles/orion_appserver.jsp) says native user support with Orion is available. "Unlike native Web servers such as Apache that utilize user IDs and security, Orion's Java technology-based system will run with the permissions of the user who started the server. Orion developers offer a security workaround by providing "native user" support for various platforms. With the appropriate library, you can start Orion with a given user ID to increase security and prevent malicious attacks. The "native user" support is available at: http://www.orionserver.com/private/native_user_support.tar.gz" Does anyone have experience with native user support with Orion? The http://www.orionserver.com/private/native_user_support.tar.gzis not a valid url (404), so can somebody send me this file? TIA Mathias Bogaert

Re: orion on unix
There is a util available on Linux called "ipchains" that can redirect all requests from port 80 to 8080. After you set it up with root user, u can run Orion as non-root on port 8080 and without clients even noticing it. Find out if there is such a tool on Unix that u are running. Never run Orion as ROOT. Even Orion team says that there might be some security leaks if running Orion as root. There is tutorial that i've read @ www.orionsupport.com called "Running Orion on Linux" that has explanation about users and everything. Take a look maybe it will help.

Re: File Upload Servlet
Hi, I solved the problem by writing a separate class to parse the ServletInputStream. It parses the stream for parameters passed and raw stream data. Works reat. What I did was I put all the ins and outs of the servlet in a separate class, -- I named it `FilePostHandler' -- and called the class in the servlet. No code has changed from the servlet -- Just isolated the code from the servlet. Then it works. I still wonder why it wasn't working. Thanks. Hello, folks! Happy new year! I wrote a servlet that uploads files to the server. The problem with the servlet is that it works but it takes too much time. I put a couple of print statements at the beginning of the servlet and at the end of the servlet for a debuging purpose. Both the print statements responded immediately and uploaded a file correctly. At the second upload, when I clicked on the upload button, nothing happended for a very long time and then started to print the two statements. The servlet part seems OK. The servlet itself is processed quickly enough as all the print statements prints almost at the same time. Now,, then what? Something must be taking process before the servlet call. I searched the orionsupport pages and found a cool class specially designed for uploading files, which is com.evermind.io.PostFileInputStream. This appeared great for the first time, but it started giving me the `500 Internal Server Error' as follows: 500 Internal Server Error java.lang.ArrayIndexOutOfBoundsException at java.lang.System.arraycopy(Native Method) at com.evermind.io.PostFileInputStream.read(JAX) at com.freightstream.servlet.FileUpload.writeOut(FileUpload.java:72) at com.freightstream.servlet.FileUpload.service(FileUpload.java:48) at javax.servlet.http.HttpServlet.service(HttpServlet.java) at com.evermind.server.http.d3.so(JAX) at com.evermind.server.http.d3.sm(JAX) at com.evermind.server.http.ef.su(JAX) at com.evermind.server.http.ef.dn(JAX) at com.evermind.util.f.run(JAX) What am I doing wrong? As usual, orion does not have much documentation on how to use the class. Please give me a clue. Any idea will help. Thanks a billion.

Complex O/R and EJB 2.0 CMP
I've been trying to get started with some O/R stuff with orion, and have gone thru the orion-cmp primer, and the complex-or example. A few problems, is that the orion-cmp primer is very simplistic, and the complex-or example (from orionsupport, which is currently down) does not have any examples, or docs on how to create and use a client application to exercise the ejb cmp entities. Does anyone have any code/examples or info on this? I like the layout of the complex-or example more so than the orion-cmp primer, because it is not required to jar it up, and classes can just be recompiled, and run (if only I could run something against it). Also, what is the difference in the EJB 2.0 CMP and orion proprietary CMP. Servlet/JDBC is sure looking a bit simpler right now. Hopefully, some info and more examples are available to help get an environment setup with CMP EJB's, to work off of. -Darren __ Do You Yahoo!? Yahoo!

Re: orion on unix
Yes, but sudo will still run orion with UID 0. This will not improve security. Then you might as well make a group called 'orion', and put all the users that need access to orion into this group. Change the dir/file perms so that it is read/writable for these users. If you try to get orion to run non-root because of security, follow the example on orionsupport. --nils Scott M. Stirling([EMAIL PROTECTED])@Sun, Jan 07, 2001 at 01:49:15PM -0500: I think there is a better solution than using ipchains (which I'm not sure is supported anywhere but on Linux, and is bound to incurr some overhead, though I'm not sure if it would be significant), or at least an alternative. Install sudo if you haven't already. You have to configure sudo with the names/groups of users and their permissions. What sudo does is allow non-root users to execute super user commands and temporarily attain super user privileges for the purpose of executing commands. You can have users enter a password to use sudo, or you can configure sudo to allow users/groups to use it without a password. In any case, make sure the actual root password and the sudo password are different, that way no one needs to know the root password except root. To use sudo, once installed, you just prefix sudo to any command in order to use it: sudo reboot sudo java -jar orion.jar etc. http://www.courtesan.com/sudo/ On 07 Jan 2001 16:54:01 +0800, Heng Chee, Lee - SG wrote: Hi, I used to run orion on NT machine and now I have to deploy it on a Sun Sparc Solaris machine.

RE: orion on unix
The best way to get around this, I think, is to use apache as a front end
and connect Orion to it.
There is excellent documentation on how to do this on
www.orionsupport.com... when it comes up. It think it is one of the
featured links on the right hand menu.
Apache runs anywhere, pretty much.
What you do is start up apache as root. Apache grabs whatever lower
numbered ports it needs (including 80) and then changes its user to
something else (usually 'nobody'). You change the configuration in
/etc/httpd/conf/httpd.conf (at least on linux) and then you can connect to
it using standard procedures supported by both apache and orion.
The main benefit of this is that you can run jrun as whomever you would like
('orion' is a good username) and you only have to worry about the file
permissions from that point on.
You DEFINITELY don't want to run orion, or any other Servlet Container as
root. The main reason is security. One of your developers could very
easily write a piece of code that would wipe out the entire hard drive, or
worse... and if anyone was able to hack in... all they would need to do is
write up a jsp file, and they have all the access they want.
Anyway. The apache thing works for us. We are able to do a lot of things
with this. One example is Virtual hosting. Each developer is able to have
their own instance of orion, running on their own virtual IP address, on
their own code base and starting and stopping it on their own running as
their own user. Apache allows for this.

Subject: RE: orion on unix
I was going to suggest something similar, which is to start up Orion as
root and then have the process change UID to a non-root user, just like
Apache. But starting the process as root is precisely the thing the
user was trying to avoid.
Throwing Apache in the front end is bound to decrease performance,
versus using Orion's HTTP server. It's certainly the easiest (and a
good portable one -- better than ipchains) solution, but I didn't
mention because it defeats the purpose of using Orion as the web server
for performance.
The security problems with running an app server as root can be dealt
with by using Java policy files. I've written them for JRun in the
past, to restrict access to just the directories, files and ports
necessary. But running an app server is a risky proposition anyway.
Even if it's not running as root it probably has access to all your
businesses' critical data via database access and Web-based business
transactions; people's credit card numbers, etc. These are much more
valuable than the files on your file system.
The real problem expressed by the original email is that regular
restarts of the server are necessary. All Java app servers suffer from
this in one place or another. Eventually, they'll all have to be able
to dynamically reload configuration settings, and any class or
component. Orion is all ready well on the way toward that goal with
dynamic reload of ears, EJB jars, servlets, etc.
A related problem is the distinction between development and production
-- why can't each developer belong to the same group, have them all stop
and start Orion on a port above 1024 for development purposes, and then
deal with this port 80 problem when it's time to move production. In
most organizations I've dealt with, the developers aren't the ones
stopping and starting the production server anyway.
