I am a user of NT server, upon downloading and configuring Cygnus Tools (Unix emulation tool for Windows) and jonas 2 I have run registry and attempted to run EJBServer and got following exception: Cannot rebind UserTransaction: javax.naming.CommunicationException: Can't Find SerialContextProvider Jonas Cannot start Transaction Service I also could not get EJBServer to read jndi.properties file but I followed a suggestion from one of the guys participating in this discussion group, namely I modified EJBServer script as follows: . $JONAS_ROOT/bin/config.env java -Dinstall.root=$JONAS_ROOT -Djava.naming.factory.initial=com.sun.jndi.rmi.registry.RegistryContextFacto ry -Djava.naming.provider.url=rmi://localhost:1099 -Djava.security.policy=$JONAS_ROOT/java.policy $* org.objectweb.jonas.server.Server I am including my path and classpath: (residing in bashrc) file PATH=$JONAS_ROOT:/bin:/usr/local/bin:$JONAS_ROOT:$JONAS_ROOT/bin:$PATH CLASSPATH="$JONAS_ROOT/;/jta-spec1_0_1/lib/jta-spec1_0_1.jar;/jndi1_2_1/lib/ jndi.jar;/jndi1_2_1/lib/providerutil.jar;/jndi1_2_1/lib/rmiregistry.jar;/j2s dkee1.2.1/lib/j2ee.jar;$JONAS_ROOT/lib/JEREMIE_jonas.jar;$JONAS_ROOT/lib/jpp .jar;$JONAS_ROOT/lib/RMI_jonas.jar;/jdk1.2.2/lib/jdbc2_0-stdext.jar;/j2sdkee 1.2.1/lib/ejb.jar;/objectweb/jonas/externals/castor.jar;/objectweb/jonas/ext ernals/jonathan;/objectweb/jonas/externals/private_jonas.jar;/objectweb/jona s/externals/xerces.jar;$CLASSPATH" as you can see /jta-spec1_0_1/lib/jta-spec1_0_1.jar is in my classpath as suggested in FAQ -------- I am also included "some" content of config file SPS=\ JDBCEXT_CLASSES=/jdk1.2.2/lib/jdbc2_0-stdext.jar EJB11_CLASSES=/j2sdkee1.2.1/lib/ejb.jar JTA_CLASSES=/jta-spec1_0_1/lib/jta-spec1_0_1.jar JNDI_HOME=/jndi1_2_1 JNDI_CLASSES=$JNDI_HOME/lib/jndi.jar$SPS$JNDI_HOME/lib/providerutil.jar$SPS$ JNDI_HOME/lib/rmiregistr y.jar IDB_HOME=/idb3_13 IDB_CLASSES=$IDB_HOME/lib/idb.jar$SPS$IDB_HOME/lib/idbexmpl.jar #ORACLE_CLASSES=/usr/local/lib/classes111.zip #JDBC_CLASSES=$IDB_CLASSES$SPS$ORACLE_CLASSES JDBC_CLASSES=$IDB_CLASSES # RMI or JEREMIE OBJECTWEB_ORB=RMI export OBJECTWEB_ORB ALL HELP GREATLY APPRECIATED, I REALLY WANT TO USE THIS TECHNOLOGY! ---- To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "unsubscribe jonas-users".
