Using MVC with Applet inside Servlet

Hello fellow Java developers,
I want to implement the Model View Controller concept inside a Bean Applet combination running in a servlet environment.
When my model (the Bean) changes, I want my Applet (the View) to get notified so it can get the update from the Bean. The Applet is incorporated inside the jsp page (e.g. the servlet). The Bean is known inside the jsp. How do I make that same Bean known inside the Applet?
When I create a new Bean during init, or in the constructor of the Applet, I get a complete other reference than the Bean inside the jsp. So, when I ask information from the Bean, I often get NullPointerExceptions, because I am referencing the wrong Bean.
Does anyone have a solution for my problem?
Regards,
Michel

hi,
a servlet is server side object, an applet is client side object.
For the communication, you should try HttpUrlConnection from applet to servlet.
another way is tu use ejb, or rmi communcation

Probem with applet and servlets

subject "not able to invoke applet from servlets"
i have attached files also..
Respected sir,
I am thomas from prateek techologies ,referred by madam Pratibha.
Actually i have to plot point marks on a image(it is a Banglore map) in an applet(Uploadimg3.java).so, for doing so, iam getting values from database in my servlet file named Mapuser_sev.java
which is in the directory
WEB-INF/classes.
now after fetching the values ,i am not able invoke the Applet (Uploadimg3.java)which is in the directory
WEB-INF/classes/mapuser.
i have used the api ,response.sendredirect("/prakash/jspfiles/displaymap1.jsp");-->up to here it's ok..
I have used the plugin tag as follows:-
displaymap1.jsp
<html>
<body>
<jsp:plugin type="applet" code="Uploadimg3.class" codebase="WEB-INF/classes/mapuser" width="400" height="400">
</jsp:plugin>
</body>
</html>
if the plugin tag is wrong then please send me the correct coding for "jsp: plugin" with explaination.
this is my directory hierarchy..
jspfiles-->directory(folder)
Prakash/jspfiles/displaymap1.jsp ----->this file has the plugin tags as mentioned above..
Prakash is my context..
WEB-INF/
classes/Mapuser_serv.class -----> this is a servlet file
mapuser/
Uploadimg3.java -----> this is a Applet file
Uploadimg3.class
Mapuser1.java ---> i used this file to fetchdata from db ,please forget this file ..
Mapuser1.class
with regards,
Thomas..

It might be the restrictions java has about opening files in a web browser. I don' t know if it's allowed or not..

Using bc4j with applets

Hi,
I was wondering if you have any tips on using bc4j in applets. The 2 biggest problems I'm having is the jar size of the applet after all libs are included
(4MB+) and the fact that I can't use XDK, JNDI, BC4J and some other libs from applets unless I sign them or change the policy file at each client using the applets.
I really think all the calls to System.getProperties(), etc. should be placed inside try catch blocks to catch the security exceptions raised by xdk, RMIInitialContextFactory, etc. and handled using
defaults for properties... it'd be even better if these properties could be set in another way as well.
Thanks in advance,
Leonardo Bueno

Using JMF with applet

Hello,
I've got an applet that consumes a lot of CPU. I'm studying to migrate this applet to a pda, but it's not enough cpu for it. I'm reading JMF docs and I decide to generate a movie with the output of an applet. �If it's possible? My idea is to create the movie on the server. I can modify my applet to avoid the use of the applet inheritance and then render the output to an standard movie format. After I will send the movie to the browser
You can see the applet here. Click on View route 3D under the flash movie.

Java will not allow us to reload any class that is dependent on a native
          library. I suggest that any classes that depend on native code should be
          put in the system classpath. If you change these classes or the native
          library you will need to restart your server.

How to use dll with applet?

I want to use a dll with a applet.
I try several solutions : signed applet, dll in jar, ... But without any result.

U can use it if u sign the applet. It is a bit trick way though.
Create an inputstream, read and copy the dll to some where path is defined (System dir for ex) from jar. Then load that library.. But u need a dummy class for that before starting applet. Rest is ur brain.. Best of luck. I tried and succeded.

Using t3s with applets

Hi -
We have a few applets accessing EJB's on WebLogic 5.1 (SP 6) which utilize
"t3" as the protocol and don't have any problem getting Contexts and issuing
requests. However, once we switch to t3s, we get an error indicating that
the server can't be found at t3s://myserver:443. This is not a firewall
problem (we've tested it with no firewall in place), nor does it appear to
be a certificate problem (WL server is running in 128-bit mode with a valid
cert, etc.) Does anyone have any experience running applets and WL,
particularly over t3s? I've included a stack trace below. Thanks in
advance -

FYI, I believe we have a legitimate fix, but we're still waiting for an

mentioned workaround, plus the layering of SP8 weblogic.security package on
top of SP6.

It appears there's a bug with WL's RSA classes in SP6 (RSAKey, RSApkcs1),

Using sockets with Applet

Hey,
I have a website which has an applet on one of the pages. I put in code that uses a socket to connect to MY computer. ( i want to use my computer as a server which stores data/accounts/etc) A SecurityException was thrown when I tested the applet. Is what I'm trying to do possible? or does something like this have to connect to a server which is on my website?
Thanks

I believe you can run something like this by signing the applet.
And then the user has the option of allowing or disallowing a signed applet to do that kind of thing. I don't know which is the default.

I would like to use the functionality of bc4j data tags inside servlets.
My aim is to do code intensive operations inside a servlet and forward the results, if necessary, to a JSP page.
The most convenient way of accessing data in BC4J are the JSP data tags. I was wondering if there is a way of instantiating them as normal Java Classes in a servlet, and using class methods to perform the database update operations that I want?<HR></BLOCKQUOTE>

How to use JNI with Servlets

Hi
i was trying to do some example with JNI. I can use JNI with standalone Java application but I just cannot figure out how I can use JNI with Servlet.
Can some one show me a sample code using JNI with Servlets.
thanks very much

hi,
I am also facing the same problem,
when I am using JNI with stand alone application it works fine but when i tried to use it with a servlet It gives unsatisfied linker error
stack: java.lang.UnsatisfiedLinkError: createSocket
     at RelayConnector.createSocket(Native Method)
     at RelayServlet.doGet(RelayServlet.java:70)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:740)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)
     at com.iplanet.server.http.servlet.NSServletRunner.invokeServletService(NSServletRunner.java:891)
     at com.iplanet.server.http.servlet.NSServletRunner.Service(NSServletRunner.java:458)
It seems i have to do some path settings in my iplenet web server.
If some one have faced the problem i would be glad to know the solution for this, i am literally bugged up,....

Use XML Digital Signature(Apache XML security) with Applet

I have problem when I use xml-security-1_2_1 library from Apache with applet and access denied errors occur.
6 May 2005 10:06:45 org.apache.xml.security.Init init
SEVERE: Bad:
java.security.AccessControlException: access denied (java.util.PropertyPermission org.apache.xml.security.resource.config read)
bla bla....
How should I do ? Please! T_T and thank you ..

An applet cannot read the local file system, connect to any other computer than the one
it came from or read properties it's not supposed to read. And I think it cannot write to any
property.
If you sign the applet or set up a policy for it the applet can do the same as an application
allthough the jre will still check the stack trace if the entire stack has the same privileges
as you signed applet.
