Problem accessing to ejb by external Servlet

[billelmehdi]

Hi, I've problem to access Ejbs deployed in jboss 3.0.4, by my servlet deployed in Tomcat 4.1.

this my lookup method in the servlet:

private ManagerHome lookupManager() throws NamingException {
Properties env = new Properties();
env.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
env.setProperty(Context.PROVIDER_URL,
"localhost:1099");
env.setProperty(Context.URL_PKG_PREFIXES,"org.jnp.interfaces");
InitialContext jndiContext = new InitialContext(env);
Object objref = jndiContext.lookup("ejb/SimpleManager");
return (ManagerHome) PortableRemoteObject.narrow(objref,ManagerHome.class);
}

and this is my web.xml:

<web-app>

<display-name>WebWAR</display-name>


<servlet-name>ServletXml2</servlet-name>
<display-name>ServletXml2</display-name>
<servlet-class>servlets.ServletXml2</servlet-class>


<servlet-mapping>
<servlet-name>ServletXml2</servlet-name>
<url-pattern>/ServletSave2</url-pattern>
</servlet-mapping>

<session-config>
<session-timeout>30</session-timeout>
</session-config>

<resource-ref>
<res-ref-name>jdbc/TestDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

<ejb-ref>
<ejb-ref-name>ejb/SimpleManager</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
manager.ManagerHome
manager.Manager
<ejb-link>Manager</ejb-link>
</ejb-ref>

</web-app>

My ejbs are correctly deployed in jboss, but when I try to access it from my servlet, I obtain this in Tomcat console:

Hi,

I had a similar problem with tomcat and RMI.
My tomcat was installed in a directory with blanks in the directorynames. Have you installed tomcat in something like c:\apache\Tomcat 4.1\ ?

Try to remove the blanks in the directorynames of your tomcat installation.

Hope it helps,
Christian

thank u ctraber, I removed this blank, I remembered that URL don't support blank, and now the problem is eliminated.
Thanks.
