RE: ANSWER: How to use pooled connections in Orion?
I have a question. If I only specify a location, not a pooled location, does Orion not do any connection pooling ? For example, if I have several container managed entity beans from the same database, would Orion share the same connection for these ?

Hello everyone, I've seen that many people are confused over how to setup pooled connections in Orion (even I was initially). Now since I figured out through documentation and through some hit and try, I would like to share these instructions. Keep in mind that this is only one way of setting it up and there are other ways to setup depending on capabilities of the driver. 1. Basically, the first step is to create a non-pooled version of your data source. This can be done by adding something like this to your data-sources.xml: data-source class="com.evermind.sql.DriverManagerDataSource" name="SQLServerNP" location="jdbc/SQLServerNP" xa-location="jdbc/xa/SQLServerXANP" ejb-location="jdbc/SQLServerNP" connection-driver="com.inet.tds.TdsDriver" username="user" password="pwd" url="jdbc:inetdae:localhost" inactivity-timeout="30" schema="database-schemas\ms-sql.xml" / The above example is for a SQL Server data source using i-net driver. Remeber to change the connection-driver, username, password and url. 2. Now, the following step will add the pooled version. Add the following lines to data-sources.xml. data-source class="com.evermind.sql.OrionPooledDataSource" name="SQLServer" location="jdbc/SQLServerDS" xa-location="jdbc/xa/SQLServerXADS" ejb-location="jdbc/SQLServerDS" max-connections="4" source-location="jdbc/SQLServerNP" pooled-location="jdbc/SQLServerDS" inactivity-timeout="30" connection-driver="com.inet.tds.TdsDriver" url="jdbc:inetdae:localhost" / Note that the source-location should correspond to location in the 1st step. "max-connections" can be changed to suit your requirements. I'm not sure whether url and connection-driver are required here. The above steps should work for any JDBC drivers. If your driver vendor supplies a data source, step 1 will be little bit different. Also, some of the driver vendors directly provide pooled data source implementation in which case 2 steps are not needed. I could successfully use i-net OPTA PooledDataSource with Orion. --Deepak
RE: Client application
Hope I haven't made any errors in the example causing to to waiste your time (as i did with my typo comp:/java/env). If so let me know. I'll fix the example. The error messages tell me that the system can't find the home interface. From the output I can't deduct what is wrong (which could be a lack of understanding from my side). I see two possibilities: 1) either there is a naming problem, or 2) resolving the class file for the home interface goes wrong. Here are some things I would have a look at: 1. Check wether there is a orion-application-client.xml in the META-INF folder/directory on your client and whether the name you are using is in there. You specify the name in java:/comp/env/name. The name in the orion-application-client.xml file points you to the name in the application-client.xml (on the client) file. 2. Check that the name in the application-client.xml file corresponds with the name in the ejb-jar.xml file on the server. 3. When you are sure that it is all correct, I would have a look at the mapping for the Home (plus the Remote and EJB) classes. Check whether the home interfaces defined in application-client.xml and in the ejb-jar.xml refer to the correct class files. All though I think that if the one in ejb-jar.xml is wrong the server will complain when starting the application. Make also sure they are in the right folders/directories (install-root/hello/ejb).

There was a discussion a while back about what you needed in Apache, net result: there's nothing that can't be done in Orion ;) now, that is a very daring statement if you look at the wealth of existing apache modules. what you probably mean is "there's nothing that cannot be done with orion if you are ready to code a filter for that" and the I'd still say that you'll find things that are at least hard to do. -snip Mike, I know that running SSL on multiple virtual-host sites works well with Apache. However, have you tried to do the same with Orion? By that, I don't mean one SSL certificate shared by multiple hosts - I mean multiple certificates, each of which is specific to a virtual host. I've tried for a long time to get that scenario to work, yet the best I can do is to have Orion recognize and share only one certificate among *all* of the virtual-hosts. That's not particularly useful. I'm to the point of placing just the SSL pages of all the sites on Apache, and using Orion only for the non-SSL part of the virtual-host sites. I was told by someone that this was an https limitation and not an Orion limitation, but it works on Apache, JavaWebServer, and IIS just fine. Are you talking name based or ip based vhosts? what magnus explained was that it was a problem with name based hosts sharing one ip address and port. for ip base hosts he gave you a solution. you're saying that it does work with name based hosts sharing ip and port with apache? robert Any suggestions or ideas?

RE: ANSWER: How to use pooled connections in Orion?
Hello, I'm certainly not an expert on this area and I can only answer from my experience. If you're not using a pooled connection, a connection is opened for each request in CMP. If you're using BMP, it's totally upto you to control connection handling. Even with BMP, it is advised that a datasource defined within the container be used so that the container (Orion) can manage connection pooling etc. In case of CMP and a pooled datasource, the connection sharing across beans is dependent on how you specify the datasource in orion-ejb-jar.xml. Say for both beans A and B, you specify jdbc/SQLServerDS as the datasource, then Orion will only use connections available from the pool of connections for jdbc/SQLServerDS. I request the Orion team to correct me if any of this is not correct. --Deepak -Original Message- From: Rick Bos [mailto:[EMAIL PROTECTED]] Sent: Saturday, October 07, 2000 5:38 AM To: Orion-Interest Subject: RE: ANSWER: How to use pooled connections in Orion?

getting EJB home from JSP

When i try to get a handle from JNDI for EJB home class within my jsp i am getting following error: java.lang.ClassCastExceptionat com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:296)at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137) This isbecause Orionis returning some wrapper class instead of thehome.(CategoryManagerHome_StatelessSessionHomeWrapper3). The same code works fine if i call from a standalone java test client, in which case Orion returns some _proxy3 class which gets casted to the proper class. Would appreciate any help and insights on this problem. Thanks Much, Krishnan
