groups and usermanager
Has anybody used more than one group outside of the defaultGroups for a usermanager? I have found that if you use EJBUserManager, and use more than one group in the EJBUser_groups table.. username='somename' value='my-admins,my-users' Only the first group in the list is used (my-admins), the second (my-users) group can't be used for authentication. Is there a workaround for this? regards, the elephantwalker
recent posts and ssl
Group, Calm down everybody. We all have the same interests here...we use orion, a great j2ee server, and we use the latest j2ee technologies. Nobody believes that national origin has anything to do with anything, except where we pay our taxes. There may have been a post by somebody, who jokingly said something or other...but nobody really believes that they REALLY believe that. I have a two questions: 1. If you have a website with SSL, you will necessarily have different urls for the secure part of the site. Is it better to run the ssl on a separate machine, or should we use a virtual host for the separate url on the same machine, and let the load balancer take care pushing the requests around? 2. So far I have only seen two places to get CA certificates for the secure site, Verisign and Tharwte. Are there other alternatives in the states for strong ssl certificates?

RE: Invalidating an Entity bean
Have you tried putting a "required" in the transaction for the entity bean? Also, if the session bean is not using the entity bean to make the change in the table, you can't use any of the j2ee transaction stuff. I would only change the table 2 through the entity bean. You can do that in the session bean by calling the home, and findby to grab your entity bean, then make the change to table 2. This way you always have the bean fresh. If you are worried about having lots of beans lying around, you can make sure that you only have one instance of your entity bean in your session bean. The petstore example in the j2ee blueprint uses this approach.

I have and Entity that has attributes A,B,C and D. These attributes are all read from database tables. A and B are read from Table 1 C and D are read from Table 2 So I have Entity Bean 1, this is loaded by the app server (perhaps by a findByPrimaryKey) method. This means that Entity Bean 1 is now a cache of the data in A,B,C and D. However while this entity bean is in the cache, via a session bean I change the data of C and D in table 2. This mean that Entity Bean 1 now has dirty data. So the question is how do I force the Entity beans to do and EJB Load. Also the data in C and D in table 2 may be shared by N number of entity beans so I may need to refresh N number of Entity Beans depending on which ones are in the cache. I only want to call EJB load for Entity beans currently in the cache and of these I only want to call ejb load for the ones that refer to the changed data. Cheers Peter

probs with bmp and foreign keys
Hello,
I am having problems with several bmp entity beans and foreign keys. I have
several beans, each bean corresponds to a table. One entity bean whose
primary key is a foreign key in several other beans is giving me problems. I
execute a remove on the the "mother" bean...and get all kinds of thrown
exceptions. The first is an SQL Exception on the removal of one row in the
project or "mother" table.
What am I doing wrong?
my tables:
create table project {
projectid varchar(32) not null,
userid varchar(32) not null,
description varchar2(255),
constraint project_pk primary key(userid,projectid)
create table material (
materialid varchar2(32) not null,
timestamp varchar2(19) not null,
description varchar2(255),
projectid varchar(32) not null,
userid varchar(32) not null,
constraint material_fk foreign key(projectid,userid)
references project(projectid,userid),
constraint material_pk primary
key(materialid,timestamp,projectid,userid));
I have an entity bean (bmp) for project and material. I have been having no
problems adding and removing projects or material entity beans with a
bean.remove() methodexcept when the entity bean pk for project is also
in material as a fk.
Orion throws this error when I execute a remove on a project bean which is
referenced in the material bean:
SQL Exception in remove ...
then I get an IllegalStateException on the project entity bean...
It only goes down hill from there...
orion throws a DeadlockException in the project passivate method
then I get a MarshallingXAException error from OrionError while
delisting bean from TX.
Where did I go wrong?
Regards,
Lawrence
RE: probs with bmp and foreign keys
You're right about that. However, in my object oriented zeal, I put a remove
for all of the referenced beans in my project bean ejbRemove method, so all
of the beans with fk's from project are removed before project is removed. I
still get the same failure mode.
I am still investigating this issue.
Regards,
Lawrence
.ps Sun has a 1 to many example in their j2ee reference guide, and they have
two solutions to the one to many case. In the first case, they do not use an
entity bean for the table with fk's, but store the references in a "helper"
class which is instanced in the entity bean and stored in a List(I think
they use cmp). They also give an example where they reference the entity
context to instance the List, but store ejb's in the List instead of
"helper" classes.

In the ejbRemove method for your project ejb, are you calling remove for the
material first? Most databases won't let you delete a row if another table
is referencing it, unless that particular db supports cascading deletes and
it's enabled. Typically in 1-M relationships like this (I assume you can
have more than one material per project) you have to delete the children
prior to deleting the parent. Hope this helps.

RE: Deploying same set of EJBs on single Orion Server but multiple data servers
Deepak, I believe you can create a separate data-source for each server, and put this in the data-source.xml. Then use a 1-1 mapping between each entity bean and the data-source. If you already have your entity bean(s) (I would use some kindof simple naming convention for your entity bean(s) to reflect their the server mybean1, mybean2, mybean3, etc. the only difference between them is their reference to each separate data-source), you can use your session bean to select which of the entity bean's to grab. Of course, you would then have to properly describe each of these in your ejb-jar.xml and application.xml. Its brute force, but its gotta work.

RE: User/Group manager guide
Guilherme,
Here Here! I'm glad somebody said it.
But without documentation, you should look at the archives to this list,
because many of these problems have already been worked out.
For example...it isn't said anywhere in the documentation, but the
EJBUserManager is the most useful device for ecommerce. With this, you can
automatically login users and create users for your website...without one
call to the EJBUserManager stuff. In order to use this, you will have to add
the following to your orion-application.xml file:
user-manager class="com.evermind.ejb.EJBUserManager"
property name="home" value="com.evermind.ejb.EJBUser" /
property name="defaultGroups" value="users" /
/user-manager
I found this tidbit in the mail archive. Then you can use the role manager
to allow users access to ejb resources, and the role manager automatically
uses the your databank with cmp to create userscreate a user like this:
try
{
RoleManager roleManager = (RoleManager)new
InitialContext().looku("java:comp/RoleManager");
if(roleManager.getPrincipal(username) != null)
throw new DuplicateAccountException(username)
Principal principal = roleManager.createPrincipal(username, password);
roleManager.addToRole(principal, role);
roleManager.store();
}
catch(NamingException e){}
catch(UserAlreadyExistsException e){}
catch(InstantiationException e){}
catch(IOException e){}
and like magic, a user database is created. Of course, you also have to make
sure your roles are part of your groups.
This is the great secret of orion...great stuff, no documentation! It took
me weeks to figure this out. I wish there was a tutorial on these simple
issues:
How do you login in a client through a database of usernames/passwords?
How do you enroll a client into a database of usernames/passwords?
How do you control access to web resources (ejb's, jsp's, servlets)?
The existing documentation on this is about as clear as mud.

Lawrence

RE: xml validation
Derek,
Go to
xml.apache.org, this is where the xerces parser project is located. I use this
parser. Here is a bit of code to parse a document...it uses sun's javax
extensions for "pluggable" parser, so it will work with any parser. If you
download the xerces stuff and put it in the orion directory, it should
work.I don'tuse the xercesjar that comes withorion, its
a little old.
The
SaxParseException is thrown when the xml isn't complient with the dtd, or when
it is not well formed xml. Notice that there is a statement:
docBuilderFactory.setValidating(true);
... this is the bit that makes the parser a validating parser. You also
might think of only using a sax parser (this example is dom), if you only want a
few bits of the xml file. This will save a little on memory.

usermanager's
Ok...I admit it, I am stuck in user-land and need a map to get out. It looks like the usermanager methodology is the way to authenticate my users on my website. However, I am a little stuck. If you look at the pet store example, nobody can log in unless you are a user as identified in the principals.xml file, or you create a new user everytime. Ok for a demo, but pretty useless for an ecommerce application. The datasourceusermanager seems pretty good, except that without the container/transaction stuff, we would have to implement all of that ourselves. That brings me to the ejbusermanager. Its part of the ejb/transaction management stuff, and provided my database can be relatively secure, we can do our user authentication. But I have some befuddeling questions: 1. If we include the user-manager declaration in the orion-application.xml, is the rolemanager the proper interface for logging users in? Or must we get the ejb reference, and hardcode the login? ,ie, userbean.authenticate(password)... 2. Will I need a separate datasource for the ejbusermanager? 3. Are there any examples of ejbusermanager authentication (soup to nuts)? Regards and buffudled, Lawrence
