Just curious if anyone has any insights why launching the JRUN4 application server from Eclipse would make hte JAAS modules not work… Looks like they aren’t even loaded. Running from the command line works perfectly fine (jrun.exe -start serverName).

[Riyad Kalla]

We aren’t currently away of JRun4 not starting up properly, how do you have it configured in your JRun4 connector settings?

[Scott Anderson]

I just tried a simple configuration of JRun 4, only configuring the install location (c:\dev\appservers\JRun\JRun4 in my stall), server name (default), and JDK location (c:\j2sdk1.4.2_06). I then started and got the following output, which appears fine:

We have our custom JAAS file in the jrun_root/servers/lib directory, and our auth.conf file in the server/SERVER-INF directory.
Again, when starting the server outside of MyEclipse the JAAS auth works perfect, it’s only within Eclipse that the authentication modules aren’t being loaded.

Is there some sort of classpathing, etc I need to consider?

thanks,
-K

[Riyad Kalla]

Kevin,
If you look into your jvm.config file in your /bin directory, are there any special JDK flags being used to specify the JAAS file? Most of the time when an app server isn’t running correctly, it’s an issue of duplicating the settings (flags, classpath, library path, etc.) in the connector settings to get it working.

[ckevinhill]

config file looks pretty bare:

#
# VM configuration
#
# Where to find JVM, if {java.home}/jre exists then that JVM is used
# if not then it must be the path to the JRE itself
#
# If no java.home is specified a VM is located by looking in these places in this
# order:
#
#  1) JAVA_HOME environment variables (same rules as java.home above)
#  2) bin directory for java.dll (windows) or lib/<ARCH>/libjava.so (unix)
#  3) ../jre 
#  4) registry (windows only)
#

#java.home=C:/Program Files/Java/jre1.5.0_05
java.home=C:/Program Files/Java/j2re1.4.2_09

# Arguments to VM

java.args=-Xms32m -Xmx128m -Dsun.io.useCanonCaches=false

# java.class.path - use this for adding individual jars or
# directories.  When directories are included they will be searched
# for jars and zips and they will be added to the classpath (in
# addition to the directory itself), the jar to be used in launching
# will be appended to this classpath

java.class.path={application.home}/servers/lib

#
# where to find shared libraries, again use commas to separate entries

java.library.path=

Does it have to do with the {application.home} being different when launched from Eclipse?

[Riyad Kalla]

I don’t believe so, we just need to figure out how is JRun launching itself differently when using JAAS versus not, and then duplicate that in MyEclipse’s connector.

I’ve never used JAAS before, are you able to send me a config file to enable it, so I can drop it into my JRun4 install here locally and see if I can figure out what is going on? If so, please tell me how you are determining that JAAS is not working, is it an error message in the console? If it requires running code, please provide it along with a quick how-to.

support@genuitec.com ATTN Riyad, with a link to this forum if you are able to send items for me to test here.

[ckevinhill]

The only problem will be that the JAAS I have will be HP/P&G specific – uses our internal Wirekey services… you would probably be able to install the component but it would be very unhappy 😉 Let me see if I can make a “simple” mock-JAAS component that we can play with….

[Riyad Kalla]

Thank you Kevin, as I mentioned JAAS is all alien to me, but just enough to figure out why the connector isn’t playing nice would be great.

[ckevinhill]

Okay email with the MOCKJAAS.jar and auth.config file have been sent….

Installation is pretty simple:
1- copy the MOCKJAAS.jar file to your jrun_server_root/servers/lib directory
2- copy the auth.config to to your (assuming server = default) jrun_server_root/servers/default/SERVER_INF directory

In one of your default web applications modify your web.xml to something like:

    <security-constraint>    
        <web-resource-collection>
            <web-resource-name>All Pages</web-resource-name>
            <url-pattern>/*</url-pattern>  
            <http-method>GET</http-method>
            <http-method>POST</http-method>
            <http-method>HEAD</http-method>
            <http-method>DELETE</http-method>
        </web-resource-collection>      
         
        <auth-constraint>
            <role-name>GLO-ROLE</role-name>      
        </auth-constraint>
    </security-constraint>
    
    <login-config>
        <auth-method>BASIC</auth-method>
    </login-config>    

The behaviour your should see is:

When started with bin/jrun.exe -start default:
A good amount of output (to system.out) and authentication no matter what user/password

With MyEclipse:
The one line that goes something like “unable to authenticate user ‘username'”

[Riyad Kalla]

Charles,
When I made the changes you specified (note: when you said “in one of your default web apps, so I used: JRun4\servers\default\default-ear\default-war\WEB-INF), and when I run JRun from within MyEclipse I get the following in the console (same as when run outside), does this look right?

NOTE: We just fixed a bug with JRun and Java 5 in the connector, the workaround is to use the following JDK optional parameters for the connector:
-Xms32m -Xmx128m -Dsun.io.useCanonCaches=false -Djmx.invoke.getters=true

(The two -D are the key ones, the -X ones are optional, I was just duplicating the default JRun params from the jvm.config file).

[ckevinhill]

Hey sorry, didn’t get an email notification on this so didn’t notice your reply.

Yes, that startup looks okay (just the default). You should start gettting more messages when you try to “view” a web application page. I’m using JDK1.4+ so the 1.5 CanonCaches fixes shouldn’t be an issue…

This fairly clearly shows the JAAS dependencies aren’t being loaded inside of Eclipse for some reason….

[Riyad Kalla]

Kevin,
I ahve filed this issue for investigation, thank you for the mock files, they will make this infinately easier to track down.

[Riyad Kalla]

Ok I’m digging into this more and I actually cannot get the MockLoginModule to appear using the JRun launcher.

I think the part I’m getting hung up on is editing the web.xml file, the module I edited was:
C:\Java\jrun-4.0\servers\default\default-ear\default-war\WEB-INF

and I changed the web.xml file to look like this:

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app  PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">


<web-app>

    <display-name>JRun Default Web Application</display-name>
    <description>The default web application for JRun</description>

    </welcome-file-list>

        <location>/errorPages/404.jsp</location>
    </error-page>

    <security-constraint>
        <web-resource-collection>
            <web-resource-name>All Pages</web-resource-name>

            <http-method>GET</http-method>
            <http-method>POST</http-method>
            <http-method>HEAD</http-method>
            <http-method>DELETE</http-method>
        </web-resource-collection>

        <auth-constraint>
            <role-name>GLO-ROLE</role-name>
        </auth-constraint>
    </security-constraint>

    <login-config>
        <auth-method>BASIC</auth-method>
    </login-config>

</web-app>

Does that look correct? I continue to get the basic output in the console, no mention of Mock. I also dropped auth.config ontop of the existing one in the C:\Java\jrun-4.0\servers\default\SERVER-INF directory and dropped the JAR into C:\Java\jrun-4.0\servers\lib

Please double check me.
