Claude,

Sorry, work has been a bear lately. Just getting around to this.

Here's the log excerpt where the bean is assigned a jndi name:
JNDI bindings for session bean named VehicleService in deployment unit subdeployment "jjgrego-ejb.jar" of deployment "jjgrego-ear.ear" are as follows:

java:global/jjgrego-ear/jjgrego-ejb/VehicleService!jjgrego.ejb.services.VehicleServiceLocal
java:app/jjgrego-ejb/VehicleService!jjgrego.ejb.services.VehicleServiceLocal
java:module/VehicleService!jjgrego.ejb.services.VehicleServiceLocal
java:global/jjgrego-ear/jjgrego-ejb/VehicleService
java:app/jjgrego-ejb/VehicleService
java:module/VehicleService

Here is the stack trace in its entirety. I set the part of the trace pertaining to the ejb in red.

Claude,

I'm using jboss 7.1.1 as my app server. The app is deployed as an ear file. When the ear deploys, I see where jboss goes through and binds the bean to a jndi name.
Like I said initially, I used the ejb to persist some info I entered. Then, I wanted to change it to where I pull information from the db prior to the page loading.

JG
I have a question about when a stateless session bean becomes available. In my test app, I have a JSF manages bean.
In testing persistence, I used the ssb to persist the info I provided later. However, after testing, I wanted to use the ejb
to pull some data from a database to populate some selectitem fields. When the app started, I am getting a null pointer
exception. I tried putting the call to the ejb in both the constructor and a postconstruct annotated method. Any suggestions
on what I can do or may be doing wrong?

Thanks

JG
Peter,


Thanks for the suggestion. I'll give the -X option a try when I get in on Mon. However as for it being a delimiter
issue, maybe. The thing is, I have another parameter, truststore, which does get set. Maybe it's bombing
after parsing the value for that...

Thanks,

Jayesh,

I'd have to say no, I'm not filtering. Within the properties file, there are about 10 different properties
I vary depending on environment, prod, development. In every case except the one, the value is
not picked up. This is frustrating because it's non consistent across poms. In a different pom, that
value will be set. To further complicate this, I copy/paste the profile values from pom-to-pom.
So there's no reason why it would work in one application and not the other.

We use maven as our build tool...for better for worse. In my pom, I define a set of default properties and values for those
properties. I also create profiles and have properties set. In the application, I have a jndi properties file in which the values
are set according to the values from the pom. for example, my keystore:

in the jndi.properties file


in the pom, it's set as:


In a profile, if I'm building on a windows platform, I may set it as follows:


However, after I build my app and examine the jndi.properties file, the value of keystore is still set to ${keystore}. For every other ${} parameter I have,
the value is picked up and set from the profile, whether it's specified from a -P option or the default profile.

Has anyone seen this before and if so, what may be causing the problem. So far, the only way to counter the problem is to hardcode the value in the
property file, which to me, defeats the purpose of profiles.

Thanks,

I have a User class containing a HashMap<String, UserAttr> of their attributes, as represented in our
ldap server. The UserAttr is wrapper class, containing a String name and an ArrayList<String> of values.
Some of the attributes contain only single values, others are multivalued.

Once I do a fetch on the user in my servlet, I set them in a session and forward the request/
response to the displaying jsp. IN that jsp, I want to to display the values of a particular
attribute. At this point, I'm not concerned about printing each value on a separate line, they
can all be on the same one.

For example say I have a user with an attribute called roles with values "DB Admin", "Sr Developer", "Architect".

In my jsp, I do the following:



This gets me the user, as does scripting, but I'm trying not to use scripting. What I want is to display the following on
the page:

Roles [DB Admin, Sr Developer Architect]

How I'm trying to do this is by
The question is can I get the values using either the "dot" operator or the "[]" operator? I've tried various forms
using both, but nothing's done what I'm wanting.

Thanks,

I have a servlet that looks up a user and sets an attribute on the request.
Next, it's forwarded to a jsp via a requestdispatcher.

In the ensuing jsp, I get the object I set in the servlet and display various
attributes of that object. On this jsp, there are 2 forms and 2 corresponding
buttons to process this user, depending on which button is depressed.

The question is, how can I get that user forwarded to a follow-on servlet?
I've tried using a hidden variable, no luck. I tried doing
in a scriptlet, but that didn't work. I'm getting a big fat null pointer exception...which I eventually
found in the HFJSP book...

Any ideas??

Thanks,

Joachim,

Ok, seems straightforward... However, what's the difference between a repository and
a mirror?

I know that you can configure where goes to pull files for inclusion in an application,
repo1 being the main one. But when I look at the settings.xml file that comes with
maven, there's really not much to it.

Suppose I have a dependency declared in my pom that pulls a unique jar file not
on the repo1 site, but can easily be found @ the jboss url of:
jboss maven

How do I configure the settings.xml file so maven KNOWS to go here to pull the
file I declared as a dependency in my pom?

Thanks.

James,

Thanks, I'll give that a try.

Cameron,

Sorry, I guess by framework, I meant how the boss wants it done, nothing
technology specific. We're using JPA and toplink. Other than that, not sure what you
need... It's not using Spring/Hibernate....etc.

I've been told to create a named query within an entity class that performs a count on the table.
In JDBC, I could do this and get an int. However, I'm not sure how to do this within the framework
I've been given. Can someone offer any suggestions with this???

Thanks,

John
Sebastian,

Yep, it worked! I switched briefly to MSIE and turned off cookies. In my servlet, I did not
encode the url. However, suppose I wanted to. If my servlet mapping is selectbeer.do, what
String do I pass to my RequestDispatcher, the encoded one, or the jsp to which I'm forwarding?

Should it be this:


or this:


Thanks,
