Error while calling servlet in WebLogic
Hi,
We are trying to call servlet in WebLogic by using http://scrmskr.apac.nsroot.net:7801/forms/HelloWorldServlet URL and getting
below error.
========================================================================
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Calling servlet from a java program
Hi
I need to call a servlet's doPost() method from a java program. I have a specific situation, where I need to call servlet from a java program. DUring this call I need to pass a file and two string to the servlet. Servelt after receiving the file and string uploads the file to the server at a specified location. I am stuck up as how to call servlet from a java program instead of a HTML or JSP.
Can anyone help me to start with this.
any suggestion is welcome.You have to establish a URLConnection with servlet from your java program.
URL servletURL = new URL("http://localhost:8080/Myservlet?str1=abc&str2=def");
URLConnection servletConnection = servletURL.openConnection();you can get the objectOutputStream
ObjectOutputStream oos = new ObjectOutputStream (servletConnection.getOutputStream());
oos.writeObject(your file object);-------------------------------------------------
In the servlet u can get the strings using request.getParameter("str1");
In the servlet u can get the strings using request.getParameter("str2");
file = new ObjectInputStream (request.getInputStream()).readObject()a lot of resources are available on this ...
hope this helps :) -
Calling Servlet from a java prog?
Hi all,
I am calling servlet from a java prog (Java Agent in Lotus Notes) by using URL and URLConnection object. how can i trigger the Servlet By using doPost method .I have to send some parameter also.
Thanx
Muthuyou need to open a connection to the servlet. Then you must call getInputStream() and getOutputStream() and use them in any way you see fit. I was trying this before and could not get POST to work unless I openned the input stream from the servlet. Strange... but doGet worked without openning the input stream???
// open a connection....
// write to the servlet
servletConnection.getOutputStream().write("whatever");
servletConnection.getOutputStream().flush();
servletConnection.getOutputStream().close();
// grab what the servlet sends back, required to do a post.
byte [] in = new byte[100];
servletConnection.getInputStream().read(in);
servletConnection.getInputStream().close(); -

Is it possible to call servlet in struts?
hello,
In struts we can submit form like this login.do
likewise is it anything possible to call servlet in struts.In struts we can submit form like this login.donot nessarily it all depends on your ActionServlet configuration in what way you configured the its URLPattern in web.xml
if you are intrested you can very well specify it to be
<servlet>
<servlet-name>StrutsActionServlet</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/strutsconfigurationfile.xml</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>2</param-value>
</init-param>
<init-param>
<param-name>detail</param-name>
<param-value>2</param-value>
</init-param>
<init-param>
<param-name>validate</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>StrutsActionServlet</servlet-name>
<url-pattern>*.sivakaminathan </url-pattern>
</servlet-mapping>
likewise is it anything possible to call servlet in struts. Why not ?
Struts itself is driver by a Servlet(ActionServlet).
all you have to do is to Configure your Custom built Servlet in web.xml with by naming the Servlet Instance,settings its configurations & specifying its URL pattern.
just like the one which you did for Struts Action Servlet
Hope that is the relavent answer for your question
