Urgent: Including a dynamically creted file in JSP

Hi all,
My problem structure is like this
In my JSP page i am haiving one String which contains a source code of the other JSP. When i use out.println to print the code it works fine for all the HTML tags, but the JSP tags don't get processed. The reason behind this could be that the string is being printed after JSP translation phase. Now my requirement is the same String which contains some JSP code should work like normal JSP.
I tried following solution, which is not working
1.In the same JSP file i created a temparory xyz.jsp file with that String contents
2.And i am trying to include that file using <jsp:include page="xyz.jsp/>
3.I am using Weblogic 7.0, So in order to deploy the application i have to create .ear file and then proceed.
4.The temperory file xyz.jsp is being creted in the domain folder of the server. which is out of the web context
5.Now i am not able to access that temperory file, since it is not in the context.
I am confused about the approch itself, because it involves IO and could make the application slow.
Is there any other way to solve this problem ??
Thanks in advance

I know that this is the "New To Java Technology" forum, so my suggestion may be more than you want to tackle, but how about custom JSP tags?
http://java.sun.com/developer/Books/javaserverpages/cservletsjsp/chapter14.pdf
They allow their body content to be manipulated / evaluated. I don't know if they're appropriate in this case, since I haven't seen your code and don't know specifically what you're trying to evaluate, but I thought it would be worth it to suggest them.

Hi
Is any one know how to create a dynamic PDF file from JSP or servlet. I need to have standard form format needs to be created and want to send the info to that form dynamically.
Is there any libraries available?
Thanks

I posted a link in this thread to a lib that lets you create PDFs from an app. They have a Java version. I have not used it but I know someone who used it with Microsoft ASP and they liked it.

i made the following code , but it did not find the file
so can any one help plz ?
        String pg=request.getParameter("page");
        if( pg!= null && ! "".equals(pg)){
                File f=new File(request.getParameter("page")+".jsp");
                if(f.exists()){
                        out.print("file exist");
                        %>
                        <jsp:include page="<%=request.getParameter("page")+".jsp" %>" />

                }else{
                        out.print("file not exist");


What does the file existing or not really have to do with it?
You can try it like this:
String pg=request.getParameter("page");
        if( pg!= null && ! "".equals(pg)){
                String webPath = pg + " .jsp";
                String realPath = request.getRealPath(webPath);
                File f=new File(realPath);
                if(f.exists()){
                        out.print("file exist");
                        %>
                        <jsp:include page="<%= webPath %>" />
        <%
                }else{
                        out.print("file not exist");
        }Alternatively you could try using a request dispatcher:
RequestDispatcher rd = request.getRequestDispatcher(webPath);
if (rd == null){
// doesn't exist
}

Include the file dynamicly by file name

in my jsp,I want include another jsp dynamicly
<%@ include file="thefile.jsp" %>
thefile.jsp should be dynamic like:
<%=String filename=="thefile.jsp" %>
<%@ include file=filename%>
I know above is not working since file only take static name.
is there any way to include the file dynamicly by file name?

String path = "..."; // to the ressource to include
javax.servlet.RequestDispatcher dispatcher

dispatcher.include(request,response);

How to include a dynamic file

Hi,
The following syntax does not work:
<%@ include file="htmls/mydocs/<%=dynamicFileName%>.htm" %>
could you tell me how to include a dynamic file?
thanks,
peterzhu

The include directive <%@ include ... does not work with dynamic file names, because it is evaluated at compile time.
You have to use the include standard action <jsp:include page=... This is executed during runtime, and hence a dynamic file name can be used.

Error when using %@ include file="/test.jsp"%&

UsingNitrox version 2.1 M3 (build 419 06022005):

This is the error :cry: when using <%@ include file="/test.jsp"%> in jsp:
Severity 2
The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files (test.jsp)
It used to work in previuos version of Nitrox. I can't use struts tiles because the tiles content is dynamic (run time) and I need it to be static (at compile time).
Have you encountered this problem? What is the fix? Nitrox bug?
I need your help please,
Alberto

M7,
I found the problem :wink: . In the java Build path having the default (ALL) is not picking up the content of the package. I had to use add multiple and include all the folders and subfolders (many L) in my packages. After that I added *.java and *.properties to select all the java files. Now it is working. I assume this is a bug in Nitrox. The default ALL should include the all the files in the path.
Thanks,
Alberto

Check the path you've specified. It may well be;
<%@include file="hello.jsp" %>or
<%@include file="/Includes/hello.jsp" %>

Pls tell me use %@ include file="myfile.jsp"% with endcoding UTF-8??

My jsp pages use some endcoding as UTF-8.
          When I use <%@ include file="myfile.jsp"%> endcoding lose format UTF-8. But
          if I use <jsp:forward page="myfile.jsp"/> it work fine.
          Pls tell me use <%@include %>
          (I use Jbuilder 6 and weblogic server 6.1)
          Thanks .


From http://java.sun.com/products/jsp/tags/12/syntaxref1214.html#8828 (emphasis mine):
page="{ relativeURL | <%= expression %> }"
The relative URL that locates the resource to be included, or an expression that evaluates to a String equivalent to the relative URL.
The relative URL looks like a pathname--it cannot contain a protocol name, port number, or domain name. The URL can be absolute or relative to the current JSP page. If it is absolute (beginning with a /), the pathname is resolved by your web or application server.
You could use a servlet in your "path" attribute and have that servlet read and return the page from a different server; there are ways to do what you want, but <jsp:include> isn't one of them.

How do I find dynamically related files where Wordpress is not involved

There are lots of posts about "Dynamically-related files could not be resolved because the site definition is not correct for this server" but they all seem to relate to Wordpress or other blogging software.
I have recently had to upgrade from DW8 to DW CS5.5 running on Windows 7 64bit. and get this error on lots of pages but there is no help about fixing it. The local testing server is localhost set up to run PHP with iis7 on virtual folders.
What do I have to do to get the dynamically related files to be found?
Thanks

I think I've cracked it - nothing to do with databases, that was a red
herring.
I had a hundred or so sites on an XP machine running Dreamweaver 8 and used
the export facility to save their settings when I moved to a Windows 7
system. Win7's directory structure is different but the testing server
location stored in the export file doesn't take account of this and part of
the path may now include directories that are viewed as shortcuts. Once the
locations are reset in Win7 terms, the errors go away.

How to import a jar file in JSP

How to import a Jar file in JSP Page.
please reply its very urgent!

Hey I am facing a similar problem:
I have this jar file lbswebservice.jar that I have to use for my application.
I added it to the classpath, I copied it in my WEB-INF/lib folder, but when I try to access classes in this package, it doesnt work.
For example the jar contains the package com.blipsystems.lbs.ws.messages.* ; that contains different classes, like the Campaign class.
I tried to use this class (just to create an object) in different context (through jsp, or just through java test classes), but it never works, i get the error: com.blipsystems.lbs.ws.messages.Campaign cannot be resolved to a type
I am a bit desperate here...

Deploying a WAR file containing .jsp and servlets (also uses JNI)

Deploying a WAR file containing .jsp and servlets (also uses JNI) on Windows 2000
We had problems making it initially work on Sun ONE Web Server 6.0 Service Pack 1 because of lack of good iPlanet Web
Server documentation on deploying such files.
This is how we went about it:
1) Make one of the servlet and JSP (must call another Java Class) web application (.war) examples work with iPlanet Web
Server.
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\HelloWorld\HelloWorld.war
and
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
a) Go to your Web Server Administration to deploy the application using GUI Web Application Deploy.
(We usually use command line, we experienced some issues with the GUI version, but maybe it is fixed in the new Web Server
service packs)
From browser, open http://yourserver:8888/
Click on Select a Server:Manage
Click on Virtual Server Class
Click on https-yourserver
Click on the Web Applications Tab
Then, click on Deploy Web Application
Enter the following -
WAR File On: Local
WAR File Path: C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Application URI: /jakarta
Installation Directory: c:\iPlanet\examples\jakarta-examples
By clicking on OK it deployed the application.
I can verify that it is deployed by selecting "Edit Web Applications" and I see the following entry:
Edit     /jakarta     c:/iPlanet/examples/jakarta-examples
Also, c:/iPlanet/examples/jakarta-examples should have the similar following directory structure ..
- [images]
- [jsp]
- index.html
- [servlets]
- [META-INF]
- [WEB-INF]
- [classes]
- [tlds]
- web.xml
- index.html
I restarted the server and accessed it using the following URL from my IE browser:
http://yourserver/jakarta/index.html
Then I clicked on the JSP Examples and tried some JSP examples.
b) Alternatively, you can also deploy the same example from the command-line.
Make sure C:\iPlanet\Servers\bin\https\httpadmin\bin\ is in your path
wdeploy deploy      -u /jakarta
          -i yourserver
          -v https-yourserver
          -d c:\iplanet\examples\jakarta-examples
          C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Restart the web server (I don't think you have to restart, but .. might as well).
2)Deploy your web-application
My Foo.war has the following structure.
You can use jar tf Foo.war to look at the file contents from command line (assuming you have JDK installed and the bin is
in your PATH)
Foo.war
- [META-INF]
- [WEB-INF]
- web.xml
- [classes]
- Bar.class
- MoServlet.class
- [lib]
- ThirdParty.jar
- [natlib]
- extlib.dll
- foo.jsp
Here is our application scenario:
foo.jsp uses a class call Bar (it is not in any package). The Bar java class uses classes from ThirdParty.jar. The
ThirdParty.jar in turn uses JNI to load library extlib.dll. foo.jsp also calls /servlet/Mo as well.
Now to deploy it, do the following:
(a) Make sure that within foo.jsp, you import the Bar class ( I don't know why you have to do it, but if you don't you get
JSP compile error).
<%@page language="java" import="Bar" contentType="text/html"%>
(b) Check web.xml (for Servlets)
Within web.xml, make sure you have the following mappings:
<servlet>
<servlet-name> MoLink </servlet-name>
<servlet-class> MoServlet </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> MoLink </servlet-name>
<url-pattern> /servlet/Mo </url-pattern>
</servlet-mapping>
(c) Deploy the application
Using command line:
wdeploy deploy      -u /foo
          -i yourserver
          -v https-yourserver
          -d c:\iplanet\examples\foo-dir
          Foo.war
(d) Change web-apps.xml file (for picking up ThirdParty.jar)
It is located in
C:\iPlanet\Servers\https-yourserver\config
You should see something similar to following after successful deployment.
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true"/>
Change it to look like following to pick up the ThirdParty.jar
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true">
<class-loader reload-interval="300"
          classpath="C:/iPlanet/examples/foo-dir/WEB-INF/lib/ThirdParty.jar"
          delegate="false"/>
</web-app>
(e) Change jvm12.conf file (for JNI)
It is located in
C:\iPlanet\Servers\https-yourserver\config
Add or uncomment the following lines:
#optional - just helps with instrumenting the jsp and servlet code
jvm.include.CLASSPATH=1
jvm.enableDebug=1
nes.jsp.enabledebug=1
jvm.trace=7
jvm.verboseMode=1
#required for JNI
java.compiler=NONE
jvm.classpath=.;C:\JDK1.3.1\lib\tools.jar;C:/iPlanet/Servers/plugins/servlets/examples/legacy/beans.10/SDKBeans10.jar;
jvm.option=-Xrs
jvm.option=-Xnoagent
# not sure if this is needed for iPlanet web server
jvm.option=-Djava.library.path=C:/iPlanet/examples/foo-dir/natlib/ -Djava.compiler=NONE
(f) Change magnus.conf file (for JNI)
We HAD to change this file in order for ThirdParty.jar file to pick up the native C++ code using JNI. Apparently, the
iPlanet Web Server doesn't pick the Environment Variable Path. Because when we had the directory containing the DLL just
in Path, it didn't work.
Change Extrapath directive:
ExtraPath C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
to
ExtraPath c:/iPlanet/examples/foo-dir/natlib;C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
(g) Apply changes from the Web Server Administration Console and Restart the web server.
You should be able to see the behaviour that you want from your application.
http://yourserver/foo/foo.jsp
Hope this was helpful!!!

iPlanet Web Server doesn't pick the Environment Variable Path. Because when we had the directory containing the DLL just
in Path, it didn't work.
Change Extrapath directive:
ExtraPath C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
to
ExtraPath c:/iPlanet/examples/foo-dir/natlib;C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
(g) Apply changes from the Web Server Administration Console and Restart the web server.
You should be able to see the behaviour that you want from your application.

Hope this was helpful!!!
