Coldfusion 9 doesn't see java servlets annotated by WebServlet annotation.

Hi.
I'm trying to run java servlet application on coldfusion 9 running on top of iis 7 server.
Also i'm using java 1.7.
Coldfusion seems doesn't see servlets annotated by WebServlet annotation. I get 404 server response.
If i add servlets mapping in web.xml everything works fine, except one thing, my application uses WebSockets, which doesn't has xml configuration,
only annotation @ServerEndpoint.
So i can't figure out, why my annotations don't work.
According to coldfusion 9 and java ee, annotations should work and it depends on java version which i use with coldfusion.
Could you help me please, may be there is a some attribute which i need to set to use annotations like @WebServlet or something like this.
Thanks.

ColdFusion 9 "does see" Java Servlets annotated by the WebServlet annotation. A 404 response means in all likelihood that there is a path issue. Verify that your annotation's url-patterns attribute includes the path to the ColdFusion page calling the Servlet.

Download it from

And don't worry, it's the correct version. Also could you check on your PC,

How can make java servlet sent soap message to other java web application

hello,
i want to make simple servlet send soap message to other java web application containing web service????
for example
web application " A " contain web service add two number
java servlet " B " send soap message contain num1 and num2 to A to add them.
how can do this????

I tried that but my problem is that the code is so old. At least what I saw. I don't know how old is too old and I'm trying to do things "right." I saw code from 1998, but I don't know if that's still what you do. It might still work, but that doesn't mean it's correct. There's so much out there on Java that so old that half the time I'm not sure what to do because some other technology in J2EE or the latest Java SDK might have come up with a new way to do things. Thanks.

Application Server 4.0 caching the Java Servlet Program

Hi all,
I am working with Oracle8i databse and Oracle Application Server 4.0. Now I need to develop some Java Servlet's Program. I successful configure the server and my Servlet program can connect to the Oracle database.
However, when I make some modification to the program and recompile it. The browser cannot refresh to the modified program. This mean that the content is't update. I think the reason may be the previous program is cached in server.
Later, I discover using the 'owsctl' utility to reload the application server can solve this problem. However, it is quite inconvenience and not favour to reloasd the server very frequently. And I guess there may have some configuration parameters in the 'OAS Manager' can help me to solve my problem.
So, anyone can tell me how to solve this problem? Thank you very much.
Regards

OAS 4.0.8.1 supports servlets. You need a patch if you implement extra path info feature of servlets. In addition, you have to bounce OAS everytime you upload new servlets. This behavior does not follow the Servlet spec and I don't know when Oracle will fix it. It is a big problem for sites trying to run 24x7.

How to deploy Servlet Application in Weblogic 8.1

Hi,
I am new to BEA Weblogic 8.1 .
I was trying to create a sample application using InelliJ IDea 5.1 , and IntelliJIdea 10.5 . i configured weblogic with IDE , but now i do not know how to deploy my application in weblogic .
I am new in IntelliJ also .
So Can anyone tell me how can i deploy a servlet application in any IDE like i also have eclipse indigo.
Thanks & Regards
Komi

Hi Komi
Basically you deploy your Servlet as a WAR File. I am not familiar with IntellJ IDE. But it should have a provision to export/create a WAR file that has your Servlet. Also I hope you already have web.xml file with 2 sections like this: First you mention full package of your servlet and give it a name. Then enter a mapping url. You will use this url to run your servlet like http://weblogichost:weblogicport/yourWebappcontextroot/myservlet
<servlet>
     <servlet-name>MyServlet</servlet-name>
     <servlet-class>com.abd.def.MyServlet</servlet-class>
</servlet>
<servlet-mapping>
     <servlet-name>MyServlet</servlet-name>
     <url-pattern>/myservlet</url-pattern>
</servlet-mapping>
Coming to deployment, I hope you already created a Weblogic Domain and have admin username/password. Start your domain. Login into weblogic console like http://host:port/console and use admin username/password. Then from Deployments section, deploy the above WAR file. In Weblogic you can deploy JAR (EJBs, java files), WAR (web jsp, html, webservices, servlets) or EAR (JAR + WAR). In your case its just a WAR file.
Refer the online docs for more details on Deployments in Weblogic.

How can I include a portal component look and feel in a java servlet

Does any body know how can i include a portal component look and feel (tables, buttons, etc) in a java servlet?

Hi José,
I don't think that is possible. But you can import the css files that ep uses for its look and feel and try to give your web pages similar look and feel. The tables and other controls used in EP are totally different and are done through complex JavaScript coding instead of simple HTML tags. If you want exact lok and feel then i thin you must go for a Webdynpro based application rather then a J2EE application with JSPs.
Regards,
Guru.
PS: Give points for helpful replies.

Location of java servlet (not jsp) deployed on Java Stack

Hello,
Why this forum? this post is related to the way of calling a java servlet deployed on the java stack, so it's related to the structure of the stack than to real java programming.
Usually, I develop JSP servlets which are easily called either with a mapping or not. I have deployed now a java servlet and added a mapping to it by modifying the xml source itselft in its descriptor, but after deployement I am not able to reach the resource.
In the windows explorer of the java stack I find in j2ee>cluster>server>apps my application as follows:
app_ear>servlet_jsp>app>root>WEB-INF>classes>my class files
app_ear>servlet_jsp>app>root>app.jsp
This time it's not a jsp that I want to call: app/app.jsp but my java servlet which lies in the classes subdir.
Could someone help my to achieve this or is it the wrong way, we can only request jsp applications?
Kind regards,
Tanguy Mezzano

Hi Vladimir,
here's my web.xml code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

     </servlet>
     <servlet-mapping>

     </security-constraint>
     <security-role>
          <role-name>DefaultSecurityRole</role-name>
     </security-role>
</web-app>
And in my jsp file, I have a form with this kind of code:
<form name="xyz" method="GET" action="http://j2eeserver:50000/SSOredirect3/SSOredirect3">
I get this error in my logs:
com.sap.engine.services.servlets_jsp.server.exceptions.ServletNotFoundException: Requested resource [SSOredirect3/servlet/AuthenticatorServlet] not found.
Exception id: [000C299F469E00650001D8E900000CCC000458E27823275B]#
Best regards,
