Deploying a servlet ear, war: help an oroin newbie
I am trying to deploy a servlet with Orion. The servlet runs fine in JBuilder. It even runs in Orion if I stick it in the default web application directory. But I want to do it right and use the ear, war files. (or do I) When I run Orion it seems to pick it up the ear and war file okay. Orion finds the ear file and unbundles the war file inside. But. When I post I get an Error... I think I set up the web.xml and application.xml just so... I based this off the orion-primer example and I even reused the build.xml ant file with some modifications. (I really like ant.) Everything builds just groovy. I even check the war and ear files and everything seems in order. I've enclosed what I think are the related parts of the application.xml, web.xml and the entries in config/server.xml. And I show the html for the form post that does not work and the post that does work (running against the default web application). If you can help, I'd sure appreciate it. I may just have the post screwed up (listed at the bottom). The web.xml file has the following entry... shortened. servlet servlet-namecom.objectgeneration.sample.EmployeeForm /servlet-name servlet-classcom.objectgeneration.sample.EmployeeForm/servlet- class /servlet The application.xml has the following entry. module web web-uriemployee-app-web.war/web-uri context-root/employee-app/context-root /web /module When I run Orion it seems to pick it up okay. I made the following entries in the Orion setup files. In config/server.xml I made this entry... application name="employee-app" path="D:\Personal\Proto\CodeGen\Employee3 \rel\employee-app.ear" / Orion finds it the ear file and unbundles the war file inside. But. When I post I get an Error... The post looks like this form action="/employee-app/com.objectgeneration.sample.EmployeeForm" method="post" And it does not work However when I post to the one I installed in the default web application it works great. form action="/servlet/com.objectgeneration.sample.EmployeeForm" method="post" -- Yours truly [EMAIL PROTECTED] _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Some pictures not loaded
Hi all, I've noticed that sometimes not all pictures are loaded on my site . When I right-click on the picture and choose "Show picture" it gets loaded! I treid with the same results on NT and on Solaris as well (all versions of orion). Is it an orion bug or server misconfiguration? Egor Savotchkin. P.S. The html page structure is not complex, so it's not likely an explorer bug.
Obtain a pooled postgres connection from JNDI datasource under Linux
Hi all, how can I obtain a pooled postgres connection from a JNDI datasource under Linux? My client code always gets a SQLException with SQLSTATE=08001: No suitable driver. Postgres driver is jdbc6.5-1.2.jar, dropped into ORION_HOME/lib (desparately also appended to the CLASSPATH). I have tried several datasource configurations in ORION_HOME/config/data-sources.xml, for instance: data-source class="com.evermind.sql.DriverManagerDataSource" location="DataSource" name="DataSource" url="jdbc:postgresql://server/db" connection-driver="postgresql.Driver" username="user" password="secret" / Did not work. (With WebLogic, a similar configuration does). The comments in data-sources.xml and the online documentation do not make me happy. From the Orion API I guess that somehow in data-sources.xml there should be 1) a datasource with class com.evermind.sql.DriverManagerConnectionPoolDataSource, where my driver gets wrapped 2) a datasource that uses the first with class com.evermind.sql.OrionPooledDataSource. Does anybody know how to get this right? Or where I can find supplementary information about Orion (besides the online documentation)?

On the documentation I have found: "shared - Whether or not multiple bindings (different sites/context roots) are to be shared. Sharing implies sharing of sessions, servlet instances etc. The default is 'false'." But I would like to know how this works. Where could I specify which context have to share its contexts?

ejbStore() not called ?!?
Hi, I'm having trouble with the following strange feature: I have data in a field (let's say A) I wish to "pack" into another field (B) for DB storage. These are, by nature, read-only objects, i.e. once created their values do not change. I've written a ejbStore() method that translates the value of A into B. ejbCreate() handles A directly. However, it appears that ejbStore() is never called and Orion stores NULL for B. Did I miss something, or is this a bug? Should I explicitly call ejbStore() in ejbPostCreate()? //Mikko

What directory are Hypersonic SQL databases stored in?
In Orion, what directory are the Hypersonic SQL databases stored in? In jBoss, they specifically have a directory called hypersonic, but I didn't spot a similar directory in Orion (maybe I didn't look hard enough). So if I have an EJB that automatically creates the data base, where does it get stored?
What happens to the database?
If I create a database application using a CMP EJB bean, like that shown on http://www.jollem.com/orion-cmp-primer, it will initially create the hypersonic database. Suppose I allow the application to be used for a while, and then update the application to add another database field. What happens to the original database when I redeploy my application? Does the database get wiped out?

RE: WAR contexts in application.xml and default-web-site.xml
yes, orion binds only by using web-app tags in web-site.xml files -Original Message- From: Gerald Gutierrez [mailto:[EMAIL PROTECTED]] Sent: Domingo, 19 de Noviembre de 2000 13:34 To: Orion-Interest Subject: WAR contexts in application.xml and default-web-site.xml What is the difference between the war-module context paths (the URL paths) that are specified in application.xml (context-root="...") and default-web-site.xml (root="...")? If I've already specified it in the J2EE-standard way, must I do it again in default-web-site.xml? Assuming that I must, I'm also confused by what the actual context root will be after I've defined it both ways. In the ATM example, application.xml has "/atm" for all three of its atm-web, atm-wap and atm-doc war modules. BUT the instructions say that the atm-web module should be bound to Orion using web-app application="atm" name="atm-web" root="/atm" / and the atm-wap module bound using web-app application="atm" name="atm-wap" root="/atmwap" / So does this mean that Orion just ignores the values in application.xml and uses the ones in default-web-site.xml?

Subject: HELP. Strange Database Connecton error.
OK list i need help.
This is kind of subtle so please read the whole message before responding.
This
certainly points to something I do not understand about Orion data-source
configuration.
I am getting an error from Oracle upon table creation. Here is the text of
the
error back from Orion:
Starting Orion
Auto-deploying addressbook (New server version detected)...
Auto-deploying addressbook-ejb.jar (No previous deployment found)... SQL
error:

Warning: Error creating table: Connection

CODE
=12505)(EMFI=4
done.
Orion/1.3.8 initialized
Looking up ERR=12505, Oracle tells me this is a problem with SID resolution.
tnsnames.ora looks fine, indeed the entry was created by Net8 Easy Config.
In
addition the following JDBC code:
public class JT {
public static void main(String[] args){
String url = "jdbc:oracle:thin:@zaragoza:1521:oradbb";
try {
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();;
Connection conn = DriverManager.getConnection(url, "jdev",
"deal");
Statement stmt = conn.createStatement();
stmt.execute("create table duff (first varchar(6),
next varchar(5))");
}
catch (SQLException ex) {
System.out.println("SQL Exception.");
ex.printStackTrace();
}
catch (Exception ex) {
System.out.println("Just a plain bummer.");
ex.printStackTrace();
}
}
}
creates a table just fine using the same SID and tnsnames.ora entry.
To make this all more confusing, I am trying to connect to Oracle on a dual
boot Linux/NT system. The Linux SID is oradba. The NT SID is oradbb.
Naturally I am only trying to connect to the NT Oracle when NT is booted and
visa versa. The Linux side works fine, it is the NT entry that gives the
error. Both Oracle installations are 8.1.5. The only difference is that on
the
NT side the user is given DBA privledges and is creating tables in the
system
rollback segment whereas on the Linux side there is a separate "development"
rollback segment. I have been posting this to the Oracle list (with no
answers forthcoming) until I wrote the JDBC code snippet I post above. The
fact that this code creates tables where Orion does not tends to make me
think
it is a Orion config issue. Here are the entries from my Orion config
files. I
understand that this is not the optimum place for the default-data-source
attribute tag but that is a separate thread.
