Access ApplicationBean from servlet

My project uses both JSF generated pages as well as servlets. I would like to be able to access an Application Bean from a servlet in the same project. The java files for the servlet are in the same directory as the package that holds the generated java page files. The Application bean should be accessible to both the generated classes as well as the servlets. Can anyone suggest how to set this up?

Hi Jim,
I am not sure I understand completely the problem you are facing, but I shall try to answer to the best of my knowledge and from what I have understood.
Since the JSF generated pages and the servlets are in the same folder all you would require to do is create an instance of the application bean and it should be accessible.
Hope this is what you were looking for.
Cheers
Giri :-)

How to run a MS Access Query from Servlet

Is there a way to execute an MS Access query from a servlet. I have a query that is doing an INSERT into the database. I tried to code the servlet to directly do the query itself, but it keeps locking the database and hanging. I would appreciate any help.
Thanks,
Justin

r u refering to the query saved inthe MSACCESS, if so then it may not be possible, bcoz it is not a pure RDBMS. otherwise the u can do it as inthe above mention thread.

Access Datasource from Servlet Engine (Tomcat)

Hi,
I'm using datasource connections in my beans and event in servlets.. It works fine in JRun 3.1 environment.
But when I port to J2EE1.3 its throwing this exception...
I just want to understand whether it is a limitation in J2EE1.3 & Tomcat environment or it is a security problem or do I have to change any configuration file so that I can make the datasource connection available outside the J2EE environment.

Problem accessing ejb from servlet

Hi,
I'm aving a problem accessing a stateful session bean from a servlet. I'm using a jndi lookup to do it because I need that a client has its own bean reference...
My code into the service method is:
InitialContext ctx;
try {
ctx = new InitialContext();
carrelloService = (CarrelloLocal)ctx.lookup("java:comp/env/ejb/Carrello");
and I have a reference to EJB into web.xml:
<ejb-local-ref>
<ejb-ref-name>ejb/Carrello</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<local-home></local-home>
<local>carrello.model.CarrelloLocal</local>
</ejb-local-ref>
If I use @EJB annotation to inject the servlet, it works fine.
Instead using jndi lookup throws a NamingException because it doesn't find java:comp/env/ejb/Carrello entry.
Any idea about the problem?

Here's something simple that I have that works:
<p> </p>
SimpleBean
<p> </p>
@Stateless(name="SimpleBean")

Access files from servlet

hi
how can i access a local text file using a servlet.

Presumably by "local" you mean a file on the server where the servlet is running? If so, you do what you would normally do in a Java program to access a local file. If by "local" you mean a file on some other system, which would be a bizarre meaning of the word, then the rules are the same as for any other Java program: that other system has to have a server running, and your servlet has to access it via that server.

Is location attribute in orion-ejb-jar.xml used to specify JNDI name? Can i get the JNDI tree showing the name mappings in oc4j? How do i correct this error?
Ravi

Ravi --
The most portable and standards oriented solution is to define an ejb-ref in the web.xml for the servlet, and then look up the name using the formal EJB UNC model.
web.xml:
<ejb-ref>
<ejb-ref-name>ejb/AppSessionFacadeHome</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>faqapp.ejb.AppSessionFacadeHome</home>
<remote>faqapp.ejb.AppSessionFacade</remote>
</ejb-ref>
servlet lookup
InitialContext ctx = new InitialContext();
Object homeObject = ctx.lookup("java:comp/env/ejb/AppSessionFacadeHome");
EJBHome ejbHome = (EJBHome)
portableRemoteObject.narrow (homeObject, AppSessionFacadeHome.class);

Please do these things:
- 1 use the [code] tags to make your code readable
- 2 tell use what actually happened, eg. show the error
- 3 simplify the problem, make an SSCCE
When that is done, we may be able to help.
Without that, here's all I can say:
I can't really tell from the pile of unformatted code what state the response is in, but if you are getting IllegalStateException, its because the response is no longer virgin and forwarding isn't permitted.

JDBC + SERVLET: inserting text data to access file from Html form

Hi everybody !
I'm trying to insert text data from my html form to access database using servlet and jdbc technologies.
The problem that I'm that the data is TEXT, but not the English language !!!
So my access db file gets - ???????? symbols instead the real text.
This is the form line that sending data to my servlet:
<form
method="POST"
ACTION=http://localhost:8080/servlet/myServlet enctype="text/html">
And this is servlet line that defines response content:
res.setContentType( "text/html" );
What can I do to get in access db file the right text format and not a ???????? symbols.
Maybe I must to ad some <meta ...> , but where ?

You're dealing with Unicode, I'd guess, and not ASCII.
I guess I'd have two questions:
(1) Is the character encoding on your pages set properly for the language you're trying to use?
(2) Does Access handle Unicode characters?
Access isn't exacly a world-class database. (If it was, there'd be no reason for M$ to develop SQL Server.) I'd find out if it supports other character sets. If not, you'll have to switch to a more capable database that does. - MOD

Accessing EJBs from a servlet

If I add my servlet classes, aurora_client.jar, mts.jar, vbjapp.jar and vbjorb.jar files to the CLASSPATH, it works fine.
The behavior is the same in JRun and Tomcat.
I don't like this solution since I have to make the CLASSPATH point to my application classes at the web server level instead of at the application context level.
Has anyone been able to solve this problem?
Thanks for your help.

Yes, I did. Actually, if I run my servlet in JDeveloper (Web-to-Go), it all works fine. I also extracted the code that calls the EJB from the servlet and I tested it in a small Java application, and it also works fine.
Things stop to work when I deploy my servlet in JRun or in Tomcat.
It appears that my code is correct, but the environment I try to run it is not, and I can't figure out what's wrong.
Can anyone help me?
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Sandeep Desai ([email protected]):
Have you provided the environmental settings in the servlet.
It should be :
import oracle.aurora.jndi.sess_iiop.ServiceCtx;
env.put(Context.URL_PKG_PREFIXES, "oracle.aurora.jndi");
env.put(Context.SECURITY_PRINCIPAL, username);
env.put(Context.SECURITY_CREDENTIALS, password);
env.put(Context.SECURITY_AUTHENTICATION, ServiceCtx.NON_SSL_LOGIN);
InitialContext ctx = new InitialContext(env);
Object obj = ctx.lookup("test/EJBHome");
HomeObject home = PortableRemoteObject.narrow(
obj,"HomeObject.class");
RemoteObject remote = home.create();
This should make it work!!

Frame access from servlet not working

Dear all,
I am running my servlets on Tomcat 5.5 and using JDK 1.6. I have a small program that uses codecs to access frames from a video file. PreAccessCodec implements Codec interface and PostAccessCodec extends PreAccessCodec. I set the two codecs into the processor's codec chain. The program is implemented as a thread and once started grabs frames and stores the images in a certain interval. The problem is this: whenever I start the thread from a main program, everything runs without a glitch. However, when I put the code in init() method of the servlet, I get the following error message:
The input format is not compatible with the given codec plugin: com.mapper.utils.PostAccessCodec@69d02b
Failed to realize: com.sun.media.ProcessEngine@1478a43
Cannot build a flow graph with the customized options:
    Unable to add customed codecs:
      com.mapper.utils.PreAccessCodec@15356d5
      com.mapper.utils.PostAccessCodec@69d02b
Error: Unable to realize com.sun.media.ProcessEngine@1478a43 I am using netbeans 5.5.1 to deploy my servlets. I doubt that the problem is with classpaths because the servlet doesn't complain when I am using JMF's classes like Processor.
I would really appreciate any help.
Thank you.

The GE.iH() method should return false for
a ..head-full ..en-headed, not headless
environment, and I expect (from what you
reported above) that will return false for both
your servlet and application, and is apparently
not the problem.It returned false when I tried GE, and it was not the problem as you suggested. However, I now noticed in the logs:
java.awt.HeadlessException
I use Netbeans for the development, and I tried using -Dheadless=true and -Dheadless=false, it did not change anything...
I think it is time to check that assumption
more carefully.
My impression is that PreAccessCodec and
it's 'Post' equivalent are mentioned a lot in JMF
example code, but are custom classes,
built to suit the use at the time. Did you write the
Pre/PostAccessCodecs for this app.?Yes I customized them from the JMF sample codes. They are in the classpaths and are correctly read by the servlet. I did some logging and I actually saw that the code inside Pre/PostAccess was logging when my servlet was run.
>
So, what I am thinking, is that while the JMF
based Processor class may well be on the
server's
classpath, perhaps Pre/PostAccessCodec classes
are not.
oes a jar appear in the WEB-INF/lib directory,
that contains the Pre/PostAccessCodec.class?
Failing that, are the classes themselves in
WEB-INF/classes/(sub-dir according to package name)/ ?Nevertheless, just to double check I checked WEB-INF directory and the classes appear correctly in their appropriate 'package-folders'.
I figured out where exactly the thread was not running. In my PostAccessCodec class, I had overloaded getSupportedInputFormats() function to return RGB format.
public Format [] getSupportedInputFormats() {
Format [] fomats = {new RGBFormat()};
return fomrats;
When I changed it to return {VideoFormat()}, the codec initializes, but I get nothing when I want to access the frame.
I guess I will have to start another thread.
@moderators, please move the post if it is inappropriate to put it in this thread, my apologies.
The problem is still there and I am not able to get the frame access not working from the servlet. :(

[Fwd: Security problem accessing MBeanServer from a servlet]

Hi,
I am trying to understand how WLS 7.0 secures a call to an MBean. Got
the following
scenario:
- I am in a servlet context
- I have created and registered an MBean with the WLS MBeanServer. Fine
so far
- Within the same call I can retrieve the MBean attributes. Fine so far
- I keep the MBeanServer reference in an object global to the servlet
context
The problem:
- When I do another request and try to use the cached MBeanServer
instance to
access the MBean, I get the following error:
weblogic.management.NoAccessRuntimeException: Access not allowed for
subject:
principals=[], on ResourceType ...
Any idea?

AlainWhat ResourceType are you trying to access. From the Exception you're
trying to access it as an Anonymous user (principals=[]) and evidently
you're attempting to access something that is protected. I can't tell
what
from the snippet you've included.

Thanks Paul for your reply.
You are right. I can access my custom MBeans if I am authenticated for example
as an Administrator. My problem is that I want any application to access this
MBean authenticated or not. I am trying to find how I could grant permission to
this MBean to everyone. Still searching.
Thanks.

Access of JSF Beans from Servlet Filter

Is there any way how can I access session JSF beans from servlet filter?
I need to check certain value of JSF bean stored in session scope in my filter.
Thanks
ferdo

Frank,
I am not sure about phase listener, this is the whole situation:
as I am not using Container Managed Security with my JSF, after I do sucessfull login into application, I need to store some information into the session scope (user etc) and in the servlet filter I need to find out if the user is connected.
I was trying to put such info into Servlet Session directly in my bean via External Context and reading the info in Filter.
This is working fine when my application is running locally (jdev oc4j) but once deployed into Application server, when user login first time, user information is somehow removed from the session, and cannot figure out why.
So I was thinking to try another approach, to find out from servlet filter if JSF bean value is set or not.
Any other suggestions? Do not want to swicth to Container Manages Security now.
