Re: Error messages
The first message means that either you started second orion process or some other application (Apache for example) use HTTP port orion configured to listen. To solve second problem you must add in your orion-application.xml file in orion-application tag next values autocreate-tables="false" and autodelete-tables="false". This will solve the problem.

The EJB app. has a query that returns all of the records from the database (informix) and displays them 25 at a time. As soon as I initiate this query, it takes about 50-60 seconds to come back with the first set of results. When I had first deployed on NT, this query would come back almost instantinaously. There are only about 800 records in the database. The difference in delay is not just a few seconds. It now take about 50 seconds more than it did on WinNT deployment. I did not write the code so I don't know what it is doing internally, but I suspect they have used CMP to hit the database with this query.

Re: Pooled Data Source
It's probably only part of the problem, but the first thing I note
is that you're not using "com.evermind.sql.ConnectionDataSource".
That's what you use when your jdbc driver is jdbc2 compliant (if
my understanding is correct...).
Other than that I don't see anything glaringly wrong...

res-type (postgres datasource) /res-type
res-authContainer/res-auth

replace (postgres datasource) with it.

Thanks for the tips. It's a servlets that makes a connection through his

Appearantly I don't even have this file/structure yet. I only have the
WEB-INF dir as I didn't say the why I should include those file(s)/dirs you

Can you please tell me where to find good information about the general

still haven't read it all.
Anyway, the server www.orionsupport.com is available again so I did read the

I now have the following dir structure in my own home dir, so the

RE: Postgress Performance
Thanks, I had tried these with little improvement. After looking at pgbench.c and reading other comments my conclusion is that postgres is this slow on doing inserts. The fast means of inserts a lot of data is to use COPY which is not useful for creating beans. It looks like my best bet is to ether switch to HSQL or at least use a combination of Postgres and HSQL. -Original Message- From: Sach Jobb [SMTP:[EMAIL PROTECTED]] Sent: Sunday, January 28, 2001 1:42 PM To: Orion-Interest Subject: Re: Postgress Performance It could be a performance issue with Postgres. By default Postgres uses a "paranoid" setting that writes each transaction to disk immediately after the transaction is completed. This is done to protect the integrity of the database, as at anytime the database could go down and data could be lost. However, when dealing with large numbers of transaction this can severely impair performance. So, you can disable it by changing your postmaster line to something like this: postmaster -o -F -D /mypath/to/datadir You can also get a little speed out of detaching from the tty you started it from by using the "-S" switch. And, of course, in terms of performance when deploying you should really tweak the number of backend connections.

Orion web server vs. apache or IIS
Hi: I just got Orion and noticed that it is recommended that we use the Orion webserver as apposed to plugging it into Apache for instance. I was just wondering what, if any functionality that the Orion web server may lack versus the others previously mentioned? I am coming into Orion and J2ee from an IIS Asp background and am little unclear as to the separation of the web app container vs. the webserver? In IIS I did not see such a separation, so when you created an application/dynamic web site, you put all the files (dynamic or otherwise) in the same directory root. With Orion, is this the same or does the static web content have to be separate from the dynamic stuff? Thanks, Stefan

RE: Connection reset by peer: socket write error Can someone help
Last weekend, I found that the source of my problem was purely IE5 and XML.
I cobbled a way to test this with Netscape and this problem does not happen
at all.
I'm basically using JSPs to generate pure XML pages with references to XSL
stylesheets so that IE5 can do the transformations (instead of using server
resources). In the following description, I don't mean to suggest that I've
debugged into IE5 and understand how the IE5 engine actually works--rather
I'm describing what seems to be the behavior.
Here's the scenario. You're looking at a web page with a link to a JSP. When
you click this link, the browser requests the JSP page. This JSP emits a
page directive to change the contentType to "text/xml". It seems that as
soon as IE5 gets this contentType switch, it abruptly drops the existing
connection to the server and immediately requests the same page again.
Well, this can cause problems on the server. For example, if the JSP page
takes a non-trivial amount of time to render itself, then the socket write
error will almost always occur since the 'peer' (IE5 in the case) always
abruptly terminates the first connection to start the second. If the first
JSP page request had time to open a database connection (before the second
page request yanked the rug), then the socket write error may also interrupt
the JSP's ability to execute enough logic to get to close the database
connection at the bottom of the page. This tends to leave database
connections hanging until they timeout.
In my case, I was using a frameset which contained four JSPs--each of which
emitted XML. In this case, each time I pressed F5, I saw four complete sets
of "Socket Write Error" tracedumps along with stranding four different
database connections. Imagine this problem in a scenario where hundreds or
even thousands of customers were requesting updates to this frameset. There
are two painpoints. First is the penalty of forcing the server to deal with
needless exception handling four times per reload action (a performance
penalty associated with dumping the stacktrace to the log file). Second are
the resources held in limbo by stranded database connections (which looks
like a big memory leak).
My workaround is to avoid sending a pure XML page to IE5. Instead I send the
XML data in an XML data island and use JavaScript to do the transformation.
[Sample code follows] IE5 is still doing the transformation but since we're
sending a real HTML file with embedded XML, instead of a real XML file, we
don't have IE5 requesting every page twice.
I would prefer to be sending pure XML/XSL to the browsers that can handle
it. But even when/if this problem is fixed by MS, we still have to
accommodate the millions of IE5 installations that don't have the patch. So
this workaround is likely to stay online for a long time in my apps.
I guess you could say that instead of fixing the problem, I'm avoiding the
situation that leads to the problem in the first place.
Cheers,
Jeff

Another variation is to have the JS actually replace the entire BODY section
of the page. This would let the XSL file have complete control over the
attributes of the Body tag. In my case, this wasn't necessary.

RE: ClassLoader.getResource not working in 1.4.5
From the JDK 1.3 Javadoc for ClassLoader.getResource(): This method will first search the parent class loader for the resource; if the parent is null the path of the class loader built-in to the virtual machine is searched. That failing, this method will call findResource to find the resource. From the Servlet 2.2 Javadoc for ServletContext.getResource(); This method allows the servlet container to make a resource available to servlets from any source. Resources can be located on a local or remote file system, in a database, or in a .war file. Maybe try using the ServletContext.getResource() instead of the ClassLoader? The ClassLoader.getResource* methods do not seem to work properly in 1.4.5. I have been trying to use these methods to load resources from my WEB-INF/classes directory, and they fail every time. After experimenting, I found out that these methods expect to load resources from orion/lib. This seems broken. I would expect that each webapp would have a custom class loader that loads resources from the webapp directories - if I need system resources I can always use the system class loader instead. This is the way other app servers behave. The methods work properly if used to access resources contained within the webapp's jars, but don't work to retrieve plain files.

Of course Orion has the file open for "writing", so what is suppose to happen in a production environment? A solution to the Orion developers may be what IIS does, a new log file for each day. Granted that generates alot of log files, but they are easy to manage, and you can write a batch file to either delete them or zip them. Obviously, one big log file is not going to work in production. -Original Message- From: Ken Eisner [mailto:[EMAIL PROTECTED]] Sent: Monday, January 29, 2001 12:25 PM To: Orion-Interest Subject: application.log file size Hey there, Has anyone ever delt with the application.log file size? We ran into a situation where orion died because it could not access the log file. It's size had ballooned to 2.1GB. Any thoughts/ideas?

BUG: Can't cast RMI interfaces in 1.4.5
In one of my webapps, I have to do an RMI call to an
outside RMI server. I'm locating the server with a
plain old traditional lookup like this:
MyRemote server =
(MyRemote)Naming.lookup("myserver");
But Orion 1.4.5 complains that it can't load the class
MyRemote, even though it is included in my application
jars in WEB-INF/lib.
This works correctly in 1.3.8.

Virtual Server question
I have read the virtual server documentation on orionsupport.com, and I understand how to host two web-sites with one IP address (ie www.site1.com and www.site2.com) . My question is what is the term for having a domain split into two sub-domains (ie www.site1.com and forums.site1.com)? Would I need to create a separate web application for www and forums? I was wanting to do something similar to www.anandtech.com and forums.anadtech.com and am just curious on the best way to do this. Thanks, Robert Johnson

As for actually saving it, I understand the problem but I haven't been able to get anything to work that will change the MIMI settings that the browser thinks it's reading. IE simply ingnores all of the header information as far as I can tell, and if the URL doesn't describe your download...bummer.

I understand why this is the case, but I wonder if there is anything, perhaps in the content header, that I could set the actual name of the file. Any suggestions would be greatly appreciated. Most browsers only consider the URL when determining the name to save as. I do not know of any specific header to modify this. To solve the problem in previous systems, I designed the servlet to include the "name.pdf" at the end of the URL, which I used as the servlet's PathInfo. This certainly solves the problem. tim.
Orion mishandles Javascript in JSP
ello,
The way Orion handles JavaScript codes in JSP files is totally wrong. The
following lines in a script block in my JSP file:
document.writeln("a class='toolbar' href='reply.jsp?action=reply' target
='msgform'");
document.writeln(" onMouseOver=\"document.images['reply'].src
='images/reply16.gif'; self.status='Reply to sender'; return true\"");
document.writeln(" onMouseOut=\"document.images['reply'].src
='images/reply16bw.gif'; self.status=''; return true\"");
document.writeln(" ");
... got translated into this:
document.writeln("a onMouseOut="\"document.images['reply'].src
='images/reply16bw.gif';" self.status="" onMouseOver="\"document.images
['reply'].src='images/reply16.gif';" class="toolbar" target="msgform" href
="reply.jsp?action=reply" "); document.writeln(" ; return true\"");
document.writeln(" ; return true\""); document.writeln("");
which is totally wrong! It works fine in Tomcat.
Is this a bug or is there a work around?

frustrated - jdbc: No suitable driver
Hi All,
I am used to WebLogic, so please pardon my ignorance...
I am trying to get my WebLogic application to run on Orion.
I have a DataSource set up to PostgreSql. It seems OK because this
Orion JSP works fine:
InitialContext ctx = new InitialContext();
out.print("brContext: " + ctx);
DataSource ds = (DataSource) ctx.lookup("jdbc/DefaultDS");
Connection conn = ds.getConnection();
// Create query and get results
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select count(*) FROM
weathersnapshots");
// List results
while ( rs.next() ) {
out.println( "br" + rs.getObject(1) + "br");
}
// Close connection - important!
conn.close();
This runs fine and gives me the count of rows in the table.
When I try to get the standalone client to the same DataSource to run, I
get this:
Context: javax.naming.InitialContext@316e52
Exception in thread "main" java.sql.SQLException: No suitable driver
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at com.evermind.sql.DriverManagerDataSource.getConnection(JAX)
at Test.main(Test.java:18)
No errors appear on the server's console. I can not imagine why I would
want to have a DB driver's jar in my client's classpath (ALTHOUGH I HAVE
TRIED THAT).
I have an application-client.xml:
application-client
/application-client
I have scoured the list archives and can not find the solution.
Remember, within the container, it runs fine. It is the standalone app
that does not work.
Using:
Orion 1.4.5
JDK 1.3
Win2K
Thanks in advance.

Re: Downloading a file via a Servlet
I tend to put the filename as pathinfo - i.e. /myservlet/made-up-name.pdf?param1=yadda If memory serves me, you need to change the servlet mapping to be /myservlet/* for this to work.

Re: Session EJB Accessibility
It sounds like you're describing an entity bean more than a session bean. An entity bean can be called by many clients although access is serialized. And certainly the role of an entity bean is to encapsulate data in a apparently-storage-mechanism-independent manner, from the client's perspective... How does the notion of a session play into what you want the bean to do?
