Subject Re: Global JNDI resources lookup behavior difference between version 6.0.39 and 6.0.41/7.0.55
Date Wed, 03 Sep 2014 15:51:10 GMT
Ok! :)

Steps to reproduce:

1)Download and unpack 6.0.39

http://archive.apache.org/dist/tomcat/tomcat-6/v6.0.39/bin/apache-tomcat-6.0.39.tar.gz

2) Create a global jndi resouce in server.xml

....
<GlobalNamingResources>
        <Resource name="jdbc/cacheapp" auth="Container"
type="javax.sql.DataSource" removeAbandoned="true"
removeAbandonedTimeout="300"
                                   maxActive="10" maxIdle="2" minIdle="1"
maxWait="10000"
                   validationQuery="select 1 from dual"
                   testOnBorrow="true"
                                   validationInterval="0"
                                   username="_system" password="SYS"
driverClassName="com.intersys.jdbc.CacheDriver"
                                   url="jdbc:Cache://localhost:1972/USER"/>

  </GlobalNamingResources>
...

3) Install psi-probe:
https://code.google.com/p/psi-probe/downloads/detail?name=probe-2.3.3.zip,
unpack and copy probe.war to webapps dir;

4)  Edit tomcat-users.xml

<role rolename="probeuser" />
  <role rolename="poweruser" />
  <role rolename="poweruserplus" />
  <role rolename="manager" />

  <user username="admin" password="t0psecret" roles="manager" />

5) Start tomcat and go to  http://localhost:8080/probe/datasources.htm

It will list global jndi resources.


Instead of Tomcat 6.0.39, use 6.0.41 and probe will not list global jndi
resources anymore.


Thanks.
