startup / monitor script?
Klaus - thanks I'll try that. On my other point, has anyone written a shell or perl script to do the following on Linux/Unix: 1) Start Orion 2) Monitor that the Java process Orion is running in is running 3) If Orion stops (ie JVM crashes) - restart Orion 4) Log the starts / stops?

Re: More JMS woes :(
it's not too unlikely these are bugs as from the impression I get on this list it could be that not many people have really used jms intensively with orion and therefore these bugs have not been discovered yet (as has been the case with several other orion features over the past few months). please file those as bug reports with bugzilla so you're sure this is brought to the attention of the orion team (+ you will be notified automatically when anything has been done about it or it is commented on). attach a test case if you can. that will speed up things considerably. robert At 16:31 15.10.00 , you wrote: I am having the following problems using orions JMS. 1.I start a transacted queue session in a standalone app and read some messages but when I call rollback the messages do not re-appear on the queue; 2.I create a transacted queue session from a stateless session bean with container managed transaction and a transaction attribute of Required but when the trasaction commits, the queue session doesn't commit.

Re: SSL question
Hello, Yeah, that's a good text, I'll add it. Thanks Mike! Regards, Karl Avedal David Ekholm wrote: That's what I call an answer! It explained a lot. Orion guys, pleas add that to your SSL howto. You can also retrieve a cert+CAcert already chained right from Thawte. Select an SSL type test cert and also check the chaining setting on the web page for test cert generation. /David - Original Message - From: Mike Atkin [mailto:[EMAIL PROTECTED]] To: "Orion-Interest" [EMAIL PROTECTED] Subject: SSL question The problem with the first command is that keytool can't find the root ca certificates in your keystore and therefore can't build up the certificate chain from your server key to the trusted root certificate authority. With the second example, keytool is using the system keystore and can locate the root ca certs in jdk-dir/jre/lib/security/cacerts. When I created my keystore I used a certificate from bt trustwise which is an intermediate ca so I had yet another cert to add. The commands went something like this (assume keystore does not yet exist): keytool -keystore keystore -import -alias cacert -file cacert.cer keytool -keystore keystore -import -alias intercert -file inter.cer // Only need this if you are using an intermediate signing authority like BT Trustwise keytool -keystore keystore -genkey -keyalg RSA -alias serverkey keytool -keystore keystore -certreq -file my.host.com.csr Get cert from csr then: keytool -keystore keystore -import -file my.host.com.cer -alias serverkey That should be that. You can do a keytool -keystore keystore -v -list and check that a cert chain has been built. You can probably get round your problem just by importing the ca certs into your keystore and then trying to re-add your server cert. HTH Mike

I get null pointer exception after calling create on an EB with EJB2.0 CMP Orion 1.3.8...
Hi All... I'm using Orion 1.3.8 and EJB 2.0 for CMP. I have written a fairley simple stateless session bean that's job is to just create a particular entity bean and populate it. This session bean is called from a servlet. When the session bean calls create on the home interface object of the entity bean it wants to create, the create method seems to execute properly and returns null. This seems true reguardless of which of two create() methods I call. After the create() method returns but before the next line of code is executed, Orion throws the following exception: java.lang.NullPointerException at CrHome_EntityHomeWrapper7.hashCode(CrHome_EntityHomeWrapper7.java:127 ) at com.evermind.util.ExternalHashSet.get(JAX) at CrHome_EntityHomeWrapper7.create(CrHome_EntityHomeWrapper7.java:335) at com.regtek.slsb.CreateNewCRBean.makeNew(CreateNewCRBean.java:41) at CreateNewCR_StatelessSessionBeanWrapper2.makeNew(CreateNewCR_Stateles sSessionBeanWrapper2.java:54) at com.regtek.protocol_servlets.MakeCR.doPost(MakeCR.java:92) at javax.servlet.http.HttpServlet.service(HttpServlet.java) at javax.servlet.http.HttpServlet.service(HttpServlet.java) at javax.servlet.http.HttpServlet.service(HttpServlet.java) at com.evermind.server.http.d1.si(JAX) at com.evermind.server.http.d1.forward(JAX) at com.evermind.server.http.ed.sp(JAX) at com.evermind.server.http.ed.so(JAX) at com.evermind.util.f.run(JAX) Of course, I have a pile of code and descriptors, but didn't want to post all that.
