Can jsp include Servlet?

can a jsp include a servlet inside in the code using the jsp include?
i am using tomcat 4.x

That depends on the type of include and the servlets function.
If you used the <% include file="relative URL" %> syntax, you can include a servlet that does a task (but does not output HTML) or a servlet that outputs HTML.
Now you can use the <% include file="relative URL" %> to <jsp:include page="relative URL" flush="true" /> but only if the servlet you are including OUTPUTS html. If this servlet DOES something other than outputting HTML then you are S.O.L. and and you cannot include the Servlet=P
Hope that helps

With iPlanet6.0 how can I include servlets in the cgi directory?

I have created a cgi directory ex. http://hostname/cgi-bin to refer to the cgi.exe's. However.. I have developed a new servlet that replaces one of the cgi programs. The servlet context must fit in with our existing architecture so the servlets context must map to the cgi URL we have in place. This works fine with every web app server under the sun .. even Sun One7... but not on iPlanet 6.0. This is because it seems that every resource mapped by a CGI directory must be a CGI program - the web server doesn't have the intelligence to know that a servlet with the same context is available and so when the CGI directory is enabled... the servlet is not found, yet when it is removed the servlet is referenced just fine.
Has anyone any ideas? Unfortunately I can't change the context of the servlet as our existing systems depend on the original cgi structure.
Many thanks,
Mark

Right /cgi must reference a cgi and /servlet is for legacy servlets that arent deployed as applications.
I dont think you are going to make it work like that, maybe do a redirect from /cgi/cginame to /servlet/servletname . That's the only thing that may work.

          You seem to be very confused about what servlets and JSPs are. These are
          things that run on the server and generate HTML. They can't possibly know
          if a user has scrolled the page, because the user hasn't seen the page yet
          when they are run. If they tried to read screen resolution, they'd get the
          screen resultion for the graphics subsystem on the server, or an exception
          if one isn't available (eg, there is no X display set).
          For these kinds of client interaction tasks, JavaScript is probably still
          your best option.

Hey all you non-ASP programmers, here's the deal. Microsoft has a Browser
          Capabilities component and they have defined a special way for you to
          populate a specially named cookie on the client side that will then allow
          the component to pick up what you sent it. In the ASP script, you then use
          the component. Behind the scenes, it works exactly like what you guys
          imagine, but Microsoft provides the format for sending the information and
          the parsing.
          The client side script does need to be written to include the information
          you want, but it would typically be written once and hidden by the lead
          programmer in a common include file where most programmers never had to
          think about it and thus might think it happened automatically.
          If you're really curious, here's an MSDN link to the details:

Capturing screen resolution in JSP or servlet

Is it possible to capture screen resolution in JSP or a Servlet? I can
          currently do it in JavaScript and write the result in to a cookie that a
          servlet can read, but is there a better solution.
          Is it possible to get the time zone of a visitor using JSP or servlets?
          Can JSP or servlets determine if a visitor has scrolled the page to view all
          of it?
          Thanks for any help
          Mike


You have to remember JSPs/Servlets run on the server. They can only
          manipulate information that you explicitely pass to them or information
          passed by HTTP. You could pass this information, gathered by JavaScript,
          through a POST or GET method.

You have to call the include method of the RequestDispatcher

out.println(" welcome");
getRequestDispachter("/myJSPDir/my.jsp").include(request, response);
}

How can i include a file in my JSP

hello i have one jst who need to use an instance of a class called Part I need to include that file in my JSP but How do i do that
How do i import my Part.java class in my JSP ???

At the top of your JSP:
<%@ import="package.*, package.Class" %>or you could do this:
<%jsp:useBean class="package.Class" id="CLASS" scope="page" />or you can use a servlet as an include and have it write HTML back to the JSP:
<jsp:include page="MyServlet">
<jsp:param name="PARAM1" value="data1"/>
<jsp:param name="PARAM2" value="data2"/>
</jsp:include>

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.

Servlet not found (jsp include)

Trying to include a servlet from a jsp. Put the servlet under the default_web_app\web-inf\classes\<package dir structure>\<servlet class name>, and included it with "<jsp:include page="servlet.package.hierarchy.ServletName" flush="true"/>
That I could think of. OC4J is serving jsps fine through Apache, but OC4J can't find the servlet. Ideas?

<BLOCKQUOTE><font size="1" face="Verdana, Arial, Helvetica">quote:</font><HR>Originally posted by Robert Cote ([email protected]):
Added "/servlet/" to the start of the include name -- that fixed it. Now, however, I can't seem to get oc4j to find my beans (located in the same hierarchy). Using <jsp:usebean...> syntax, the usebean statment seems to get processed, but accessing the bean through it's id yields:
Syntax error in source
/mapsis/contacts4_mockup.jsp.java:30: Undefined variable or class name: <bean id>
I'll try messing w/ the syntax, but thanks in advance for any ideas.<HR></BLOCKQUOTE>
Is your bean part of a package ?
Here is an example
<%@ page import="java.sql.* , oracle.jsp.dbutil.*" %>
<jsp:useBean id="cbean" class="oracle.jsp.dbutil.ConnBean" scope="session">
<jsp:setProperty name="cbean" property="User" value="scott"/>
<jsp:setProperty name="cbean" property="Password" value="tiger"/>
<jsp:setProperty name="cbean" property="URL" value="jdbc:oracle:thin:@dlsun:1521:P817"/>
<jsp:setProperty name="cbean" property="PreFetch" value="5"/>
<jsp:setProperty name="cbean" property="StmtCacheSize" value="2"/>
</jsp:useBean>
Hope this helps.. sorry for the delay in replying..

How to include servlet in JSP using Include Directive?

Hi experts,
am a beginner to JSP.. I want to know,
is it possible to include a servlet in jsp using include directive? could any one explain me...

No it is not possible.
Include directive is like copying and pasting some text into a JSP file, and then translating/compiling it.
So the only thing you can include with the <%@ include %> directive is a jsp fragment
It is a static translation/compile time include and thus will always be the same
By contrast <jsp:include> is a runtime include, and includes the result of running the imported url.
That URL has to be a complete/standalone jsp/servlet/whatever. However as it is runtime, it can take parameters where the include directive can not.
Does that answer your homework question?
Cheers,
evnafets

In a jsp page how can i include another page from differenct web context

Hi,
i want to include a page from another web content to my page. How is it possible. For example in a jsp page i want to include "http://www.google.com". How is it possible. can i use <jsp:include tage for this purpose? any idea?
Edited by: JavaHeroPrince on Apr 2, 2009 12:05 AM

I'm afraid you cannot do that using <jsp:include/> tag.
However, you can achive this using <c:import/> tag which comes with JSTL core tags.
Please find the below example of how to go about.
<%@ taglib uri = "http://java.sun.com/jstl/core" prefix = "c"%>
<c:import url = "http://www.google.com/search">
<c:param name="q" value="c%3Aimport+jstl"/>
<c:param name="rls" value="com.microsoft:en-us"/>
<c:param name="ie" value="UTF-8"/>
<c:param name="oe" value="UTF-8"/>
<c:param name="startIndex" value=""/>
<c:param name="startPage" value="1"/>
</c:import>

How can i upload a image file to server by using jsp or servlet.

Hi,
I m gurumoorthy. how can i upload a image file to server by using jsp or servlet without using third party API. pls anyone send me atleast outline of the source code.
Pls send me anyone.
Regards,
Gurumoorthy.

I'm not an applet programmer so I can't give you much advice there.
If you want to stream the file from the server before it's entirely uploaded, then I don't believe you can treat it like a normal file. If you're just wanting to throw it up there and then listen to it, then you can treat it like a normal file.
But again, I'm not entirely certain. You might be able to stream the start of the file from the server while you're still uploading the end of it, but it probably depends on what method you're using to do the transfer.

How can I include a JSP, Maximized, and retain look and feel(WSRP)

I have created a page group and defined a root page with a certain look and feel. There are two portlets on the page. Once the user clicks on a submit button, the portlet performs some action and includes a jsp included in the EAR file. The portlet needs to maximize the UI to display the jsp correctly.
Once control returns back to the screen, the look and feel is lost and uses Oracle's default style. I have two questions:
1. From the portlet, how can I retain the look and feel of the page group when referencing "external" jsp (i.e JSPs in the deployed portal EAR file).
2. How can I "redirect" the user to the home page in a standard way? If there is not a standard way, how do I use the Oracle specific utilities to do it?
All of my JSPs are developed externally out of the scope of the Oracle Portal.
Environment - Oracle Portal 10.1.4 on Release 2 using WSRP to contact Oracle Release 3, hosted EAR file (WSRP Producer).
Thanks in advance.

Hi José,

How can I include a jsp file in other jsp from different applications?

          Hi,
          I'd like know if it´s possible to include jsp or servlet from different applications.


          Thanks Deepak but I think you don´t understand me.
          I would like the include works like a normal include. I have a jsp in my application
          and , when the client requests this jsp, in the jsp should be added the result
          of the other jsp ejecution that belong to other application in the same domain.
          Is this possible?
          Thank you very much.

Flush parameter of jsp:include has no effect on servlet code

I am running 9.0.3 and my jsp code looks like:
<jsp:include page =".." flush="false"/>
but the resulting servlet code is:
pageContext.include( __url);
Which defaults to flushing the buffer!
Does anyone know a work around or if Oracle is going to fix this?
Thanks,

        ...needed this so custom paint would use AA. In my app I wrote text in my component and it was not AA, this turned it on.
I don't think I had the same problem you, as my jlabels were always aa.
