Chris, Alex,
Consider yourselves lucky...at least on a relative basis :).I've now logged
around 7 hours on this problem and still no progress! :((
I've tried every combination I can think of. I have the following JAR
files in my WAR file's WEB-INF/lib:
- ejb.jar
- jnp-client.jar
- jboss-client.jar
- jta-spec1_0_1.jar
- jaas.jar
- struts.jar (which is found with no problem, BTW)
- ejbpeopleClient.jar (contains all my application classes, servlet, and
EJB interface classes)
In addition, I have tried putting my servlet and EJB interface files in
either WEB-INF/lib (as a JAR) and WEB-INF/classes, to no avail.
My system classpath contains the following:
"D:\jakarta\dist\tomcat\lib\ant.jar;D:\jakarta\dist\tomcat\lib\jasper.jar;D:\jakarta\dist\tomcat\lib\jaxp.jar;D:\jakarta\dist\tomcat\lib\parser.jar;D:\jakarta\dist\tomcat\lib\servlet.jar;D:\jakarta\dist\tomcat\lib\webserver.jar;D:\ejbpeople\projects\build-app\conf;D:\JBuilder4\jdk1.3\demo\jfc\Java2D\Java2Demo.jar;D:\JBuilder4\jdk1.3\jre\lib\i18n.jar;D:\JBuilder4\jdk1.3\jre\lib\jaws.jar;D:\JBuilder4\jdk1.3\jre\lib\rt.jar;D:\JBuilder4\jdk1.3\jre\lib\sunrsasign.jar;D:\JBuilder4\jdk1.3\lib\dt.jar;D:\JBuilder4\jdk1.3\lib\tools.jar"
As you can see, I'm running this in JBuilder...
I have my jndi.properties file in D:\ejbpeople\projects\build-app\conf,
which is on my system classpath.. The properties are read, but don't seem
to work, so I set up the properties by creating a java.util.Properties
object properly ,initialized before calling new InitialContext(props);
When I try to call context.lookup(), I keep getting:
Cannot instantiate class: org.jnp.interfaces.NamingContextFactory
javax.naming.NoInitialContextException: Cannot instantiate class:
org.jnp.interfaces.NamingContextFactory. Root exception is
java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory.
<Full exception trace below>
I just cannot figure out why NamingContextFactory is not found. It's in
jnp-client.jar, which is in my WEB-INF/lib directory of my WAR file. I
double checked, and I'm definitely using the right version JAR files from
JBoss. All of my application classes are at the same "level" - all in the
WEB-INF/lib directory, except for the JAR files listed in my system
classpath, above. In fact, my servlet classes are in the same JAR as my
EJB interface files, and the servlet classes are loaded and executed with
no problem. I cannot think of anything else to try...does anyone have any
idea what I may have setup incorrectly, or how to further debug this problem?
Thanks very much for any help,
Rick Horowitz
