Is there any way for me to set the timeout interval for an EJB? Thanks Eric
Servlet API problem
Hello, I'm trying to compile JetSpeed (http://java.apache.org/jetspeed/site/overview.html) with Orion jars and I'm having a problem: /home/yann/java/jetspeed/bin/src/org/apache/jetspeed/util/servlet/JetspeedServletRequest.java:132: Method removeAttribute(java.lang.String) not found in interface javax.servlet.http.HttpServletRequest. req.removeAttribute(name); According to the specs, this method should exist ...

Ant build files
Would anyone be so kind to show/send me some build files that generate a .ear file, containing all the necessary META-INF directories, XML files, .jar files, .war files, etc. ? Perhaps we can develop a single build.xml file for use in most J2EE projects.

RE: Makefiles
Can we get these make files (generic J2EE ejb-jar.xml ones) or are they proprietary? Would seem like a good thing to include in the Orion download now that Ant is becoming more popular? I used it daily to build everything, taglibs, ears, jars etc...

Clustering
Hi! My name is Roy Lou. I am new to orion-interest. Could you shed some light on the topic of how to set up clustering for servlet and jsp? Is there any document about how to do it? Thanks. Roy Lou SPSS Inc.

Hi Ernst, > However, I find ant less powerful than make, because with the > Makefile I am building I just have to change the name of the application > and the names of the beans in order to get a new makefile for a different > EJB application. I would contend that Ant can be as powerful as you can be bothered to make it - you can write your own Tasks and there are plenty of helper classes available. Case in point: the Task I wrote to generate the ejb-jar.xml needs only to be told where the application package root is - I don't even specify the names or types of the EJBs. It enumerates over the classes in the application, loading classes up, and using reflection to tell what they are, before spitting out the appropriate XML. > Although ant seems very nice at first glance, I don't > think it is powerful enough. What I am missing is `patsubst' > functionality. It may be in there, but I haven't found it yet. /:) There's regexp (http://jakarta.apache.org/regexp/index.html) if you want to pattern match generally, and if you want to apply some algorithm to a certain subset of files in a hierarchy, then the DirectoryScanner class in the ant package hierarchy is a good bet.

Re: Makefiles
Hi James, Thank you very much for the pointer to Ant. I am evaluating it as we speak. However, I find ant less powerful than make, because with the Makefile I am building I just have to change the name of the application and the names of the beans in order to get a new makefile for a different EJB application. Although ant seems very nice at first glance, I don't think it is powerful enough. What I am missing is `patsubst' functionality. It may be in there, but I haven't found it yet. /:) Ernst [EMAIL PROTECTED] wrote: > > Take a look at Jakarta Ant > > http://jakarta.apache.org/ant/index.html > > Written in Java, uses an XML makefile format... very nice!

Re: Makefiles
Take a look at Jakarta Ant http://jakarta.apache.org/ant/index.html Written in Java, uses an XML makefile format... very nice! Our build is entirely automated using Ant and our customised Tasks.

Datasource definitions and the meaning of their location attributes
Title: Datasource definitions and the meaning of their location attributes Hi, A datasource is defined in Orion's data-sources.xml something like this: name="Test" class="com.evermind.sql.ConnectionDataSource" location="jdbc/Test" pooled-location="jdbc/TestPool" xa-location="jdbc/xa/TestXA" ejb-location="jdbc/TestEJB" url="jdbc:oracle:thin:@Test:1521:Test" connection-driver="oracle.jdbc.driver.OracleDriver" /> Could somebody explain what the different types of location attributes are used for? The Orion docs are rather terse in this regard. I've tried making an entity use one of the other locations for getting it's DataSource and thus Connection but I get various exceptions. The entity only works when it uses the name defined in the plain location attribute.

RE: Referring to a datasource in EJB deployment
Here's a little more info on Orion not finding my datasource, when deploying my container managed entity bean. In orion-ejb-jar.xml I haven't used , instead I have used . According to the docs you are able to specify the name of the datasource there, which is declared in data-sources.xml (). This worked in 0.9.4, but it isn't working in 1.0rc1. Anyone out there expiriencing the same problem, anyone got any solution? /Esa > > > I have gone from Orion 0.9.4 to 1.0rc1 and in this latest > > release > Orion > > can't find the datasource that I have specified in the > deployment > descriptor > > for my container managed entity bean.
