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

Uhm, this is actually wrong. There's no reason you can't communicate directly with EJBs from a JSP (I do it alot).

Re: jsp.reuse.tags
Hello again, Hmm, I should update my own reply, because that example is actually a bad one, since it's illegal to reuse the tag in that specific case. However, the principle is the same. Tags might be reused under certain circumstances, and they assume this isn't done. Regards, Karl Avedal Karl Avedal wrote: Hello Luis, Let's say we have this in a JSP: foo:bar baz="123" baz2="234"/ Some text foo:bar baz="123"/ In a JSP container, tags might be reused (the tag instances are pooled), so when the tag foo:bar is used for the second time above, the optional attribute baz2 may still have the value "234" since the same instance as before is used, so when having optional attributes like above, you have to be careful. This is exactly what the pet store is doing and they assume that the tag will not be reused (that they get a clean instance every time). This probably comes from the fact that they implemented using the J2EE RI. The J2EE RI is not meant to be fast, but just to follow the spec, so that implementation does not reuse the tag instances. So when they tested the petstore on the RI it worked fine, but it did not work in containers doing this optimization. For this reason we provided a property for Orion to turn off the tag instance reuse optimization.

RE: probs with bmp and foreign keys
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.

Mapping Users/Groups to Roles
I know this question has been asked before but I couldn't find an answer in the archive. For starters in my orion/config I have the default principals.xml that has the groups users, guests and administrators and the users user, anonymous, guest, admin. The group assignment of the users is the default. In particular, guest is a member of guests. Now, in my ejb-jar.xml I have, assembly-descriptor security-role role-nameguest/role-name /security-role method-permission role-nameguest/role-name method ejb-nameaccountMgr/ejb-name method-name*/method-name /method /method-permission /assembly-descriptor When I deploy and try to access this EJB, I get an exception stating that guest does not have permission to call the ejb methods. How does my role guest get mapped back to the user guest in the global principals.xml file? There seems to be some crucial piece that I'm not grasping. On a similar note, what is the default role permission when no method-permission is defined? I'm assuming it's wide open. Is there a way to change the application default so that I have to explicitly loosen up the restrictions and not the other way around? Also, what is the default container transaction attribute when one isn't specified for a particular method or ejb?

Problem with Multiple JSP's
Hi I have started using Orion Server first time. Before this I have done development using Weblogic but I liked this more. I am using JBuilder as my IDE and I have set it up to start Orion server through it so that I can debug my application. Now while doign that things run fine but the problem comes when I try to call one JSP from another one. I tried it with default.jsp to call another one from it and otherwise too. Any jsp calling another one kills the orion server and it shuts down and page becomes unavailable. The tragedy is that once if I reference that page explicitly and then start my application with a different JSP calling this JSP(which could any one but being called from another one), then it starts running. SO I think it has somehting to do with the configuration issue fo Orion and I am unable to figure it out. I don't understand how to make the Container to know where the next JSP is I have already tried giving the directory path for all the JSP as they are kept together in "web.xml" but that does not help either. Also I am using different directory structure which is out of Orion default-web-app structure. Its standalone but I put the ".ear" in applications directory of Orion and deployment information goes to Application-deployment. Please somebody help me as I am trying to figure out this problem for 2 days now and its getting on my nerves. I thought that Orion seems very reasonable to work with but these kinds of problems which has no related documentation and no support available in USA, makes things really difficult. Any kind of suggstion, guidance or help woudl be really appreciated. Thank you. Shelly Mehra

Re: jsp.reuse.tags
OK, I think I understand what's going on. I don't know whether you are familiar with the java pet store taglibs, but they are only used in two files: template.jsp and ScreenDefinitions.jsp. What I notice is that in the ScreenDefinitions.jsp file some screens use three parameters and other use four. So I'm guessing that if I create a blank.jsp and use it just as a filler in the screens that have three parameters (so that they have four instead) I'll solve the problem and will not need to use the jsp.reuse.tags flag. Would that work?

Re: Using Orion As a Plugin to IIS for Servlets/JSPs
I have a question..why would you not be able to use Orion as the web server? It actually serves HTML pages as fast (if not faster) than IIS does. Its very easy to set up. Not to disparage Orion (a great product!), but it's extremely unlikely that Orion will approach IIS's speed of serving HTML pages. IIS is highly optimized using native NT APIs to perform this task extremely quickly. Does anyone have any benchmarks? Of course, if Orion serves your pages fast enough for your needs, then it doesn't matter if IIS is faster. - Kyle Cordes - www.kylecordes.com

Ofcourse it works, install suns com-rmi bridge and youre off.. But it will not work with isapi or any other filters.. You have to redirect inside the code... And for the one mentioning weblogic..You dont get any isapi filters for Weblogic either, you have to redirect calls the same way as you have to do to orion. It would be the same as to claim Apache has to get an isapi filter for IIS to serve php for IIS. Ok mention JRun that is a servlet engine and not a webserver, that one would ofcourse have a filter to run jsp and servlets inside IIS (or do a invis redirect) but thats not a webserver.. Ps: Orion is faster than IIS, so is most other webservers.. IIS is full of memory leaks and other stuff that make it bend when the load is really hard, and over time.

To use Resin as an EJB client with Orion follow these steps:
1)Under Orion do nothing :)
2)In Resin add orion.jar, ejb.jar, mail.jar (from orion) in your app
WEB-INF/classes dir
3)In Resin in your app web.xml add these lines:
classpath id='WEB-INF/classes/orion.jar'/
classpath id='WEB-INF/classes/mail.jar'/
classpath id='WEB-INF/classes/ejb.jar'/

init-param
java.naming.provider.url="ormi://myOrionHost/MyApp"/
init-param java.naming.security.principal="admin"/
init-param java.naming.security.credentials="xxx"/
/jndi-link
4) Write your servlet/JSP as you would in Orion so for example if you have a
SessionBean called MyBean (in your ejb-jar.xml) your lookup should use this
string ("java:comp/env/ejb/MyBean")
5)It's all

Howdy. I submitted this question last week, but I'm
hoping it got lost in the multiple-delivery storm, and
not that y'all are ingoring me ;-)
I have a web page which calls a servlet, and passes
parameters. I know he servlet is called (I see
it running), but it doesn't recieve any parameters.
Infact the in the servlet the query string is null.
Any suggestions?
Heres a snippet from the html page:
A
href="datamaintenance?TABLENAME=ASSEMBLY_TEMPLATES"
Heres some of the code from the servlet: public void
doGet(HttpServletRequest req,HttpServletResponse res)
throws IOException, ServletException
{
System.out.println("request attributes: " +
req.getQueryString());
System.out.println("request attributes: " +
req.getServerName());
System.out.println("req.getParameter(thisParam)" +
req.getParameter("TABLENAME"));
All the debug lines print. The getQueryString returns
null; getServerName returns localhost (which is
correct), and the getParameter returns null (note that
the name matches the value in url that called the
servlet).
I'm perfectly willing to accept that I may have made a
stupid mistake here, but I sure am having trouble

You're right about that. However, in my object oriented zeal, I put a remove

.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

However, if you are using EJB 1.1 and are storing a Collection of things in an Entity bean, then IMHO the container MUST delete the dependent objects along with the entity. I have reported this as bugzilla # 52. See that for further details. Nick At 04:53 PM 9/26/00 -0700, you wrote: Hi, Having some problems while deleting a EJB. When i delete the ejb by ejbobject.remove() method the dependent objects and relationship entries are not deleted from the database. Should this not be done automatically by the app server. Is this a problem in Orion or is there some explicit delete that needs to be done in the remove method implementation in the bean. Would appreciate any help on this. Thanks Krishnan
Re: Serializable + Orion 1.3.8 + Postgres 7.0.0 not working
Support for InputStreams as parameters has not been implemented in the Postgres JDBC drivers. It's open source, so anyone can give it a try.. But it's possible in 95% of all cases to make it without serializing the objects, since Orion has very good OR-mapping capabilities (List, Set, Map, bean etc).

A coworker and I are trying to create a servlet that will run on his computer under Tomcat. The servlet is attempting to lookup and use an EJB deployed on my computer under Orion. When the servlet performs the context object's lookup method (using the String literal "java:com/env/fungi"), we get the following exception displayed on his computer: "Exception: javax.naming.NamingException: java:comp/env namespace is only available from within the J2EE environment." A command-line client application run on the same coworker's computer IS able to successfully lookup the same EJB on my computer using the "java:com/env/fungi" String literal. We have been unable to find any documentation about the NamingException described above. If the message can be trusted, it appears as though our servlet is not perceived to be part of the "J2EE world". We are not sure why. Does anyone know anything that can help us? We would appreciate any assistance that can be given. Thank you. Mark McLain Systems Developer Sybron Laboratory Products Corporation

RE: Can't create xxxxx.jsp.jspCache files
Thanks Magnus. The problem we are having is that when Orion attempts to create those files a permission denied error is issued by Linux. This does not happen when Orion runs as user root, but rather when it runs as user orion. However, as user orion it has full control over its own directory tree, so the implication is that Orion is attempting to write outside its own directory tree. For example, if we first run Orion as user root and then execute the JSP checkbox example, the checkbox.jsp.jspCache file is created and runs. If we then run Orion as user orion the checkbox JSP example still runs, but now the other JSP examples fail because permission is denite to write a file. Here is the key: We assume the denied file is the JSP cache file, but it could be another intermediate file or something else. So we are wondering exactly how that JSP cache file is created so we can be sure to give user orion the proper permissions. I apologize if it seems that I am going on and on about this, but we can't let Orion run as user root and we can't leave all Orion files world writable. So we are looking for a solution that is secure. Thanks again...

If we run Orion as root, it runs fine and creates the files, which persist. If we then run orion again as user orion, the JSP examples that we ran when Orion was root run fine, indicating that Orion, when running as user orion, can at least read these files.

Interesting ejb Error!!!
Hello there,
I am trying to access the orion's demo/ejb/cart ejbeans via servlet or jsp
file. The code is
try
{
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.ApplicationClie

env.put(Context.PROVIDER_URL,"ormi://10.1.1.59/ejbsamples");
env.put(Context.SECURITY_PRINCIPAL,"admin");
env.put(Context.SECURITY_CREDENTIALS,"123");
Context context = new InitialContext(env);
Object homeObject = context.lookup("java:comp/env/MyCart");
CartHome home =
(CartHome)PortableRemoteObject.narrow(homeObject, CartHome.class);
}
//Cart cart =
(Cart)PortableRemoteObject.narrow(home.create(), Cart.class);
}
catch(Exception ee){
return "Error Becomes ..."+ee;
}
I am getting error as,
java.lang.ClassCastException: CartHome_StatefulSessionHomeWrapper2
If I access the ejbeans from an application on command prompt, it is working
fine.
I really wonder why the same code is not working in servlet/beans/jsp.
Can anyone help me?
