Jakarta Datagrid Taglibs and Servlet 2.4

Dear All,
Please help me with this situation
we would require to have this Jakarta Datagrid taglib (with the servlet 2.2 support) in my web application, but my web-applications uses servlet 2.4 version.
If we change my servlet version to 2.2 for the benefit of Datagrid, we lose JSTL, Expression Language support.
we got struck here and we are not familiar with struts and jsf, where we came to know the availability of datagrid using these.
Kindly requesting you to help us to solve this issue or guide us to a datagrid control works servlet 2.4 version.
I am not a programmer, i am writing this message on behalf of my programmers (freshers). Please do guide us.
thanking you,
S. Sithi Vinayagam

dear all,
why i am not getting any response from you all,
Is this a common question, that will not be anwered any more
or
is there is a better way to ask this type of help from all the developers over there.
Kindly i am requesting you once again to suggest me a better solution (not any commercial soultions) with this type of Data Grid solution for my web application

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!!!

Using variable names in the jakarta img taglib

I am using the jakarta image taglib for manipulating images, it is working fine with static names like this
<img:image src="xyz.jpg"..etc
but once I replaced the image name with this scriplet
<img:image src="<%= book.img %>
I got noting although I am sure that my scriplet has value but the image didn't show up, any idea
thank you

the problem was solved I've used the EL notation instead of scriplet and it worked
<img:image src="${book.img}..etc
thank you

LDAP protection for JSP and Servlets

Environment: WL 5.1 sp 8 on Solaris 7
Question: I want to use LDAP Security on my site. Does Weblogic only utilze LDAP
for servlets. What about my JSP files? And no, I can't protect just a directory
with iPlanet Web Server because my JSP files are all over my directories and my
servlets are in my /servlets directory. I need security on some of the jsp files.
how would I accomplish this?

Hello
What do I install in order to create and use .jsp's
and servlets and jdbc connectivity as well? Is it
J2SE or J2EE. The answer is "Yes."
In order to use J2EE, you need J2SE. If you do not feel comfortable with J2SE and programming Java in general (as is suggested by not being able to differentiate between J2SE and J2EE and how to download one/both), J2EE may be a bit complex to get started with.
My suggestion:
1) Start Here: http://java.sun.com/learning/new2java/index.html
2) Download J2SE: http://java.sun.com/j2se/1.5.0/download.jsp choose the JDK 5.0 Update 3
3) Do a beginners Java Tutorial: http://java.sun.com/docs/books/tutorial/index.html
4) Read a book, try a lot, get comfortable doing it.
Then Choose the JDBC:
http://java.sun.com/docs/books/tutorial/jdbc/index.html
Then, only after being compfortable in how Java and JDBC work, move to J2EE
1) Download a Server (examples):
Full J2EE implementation: J2EE Software Development Kits (SDK)
Servlet/JSP Engine (Tomcat): http://jakarta.apache.org/site/downloads/downloads_tomcat-5.cgi
There are others, Tomcat is fairly popular.
2) Read the server's documentation thoroughly
3) Read a J2EE tutorial: http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html
Note: depending on your server, the above tutorial may only be partially relevant.
The download section is overwhelming
and confusing to me :(
Thanks for any guidance.

Difference between web server and servlet container

I can't able to figure out the techincal difference between web server(such as java web server) and servlet containers(such as jakarta-tomcat).If you please let me know then I will be very thankful to you.

The web server serves html pages to browsers that request pages. It can also send images, javascript, flash content, and a few other things. When a request comes into the web server for a servlet or jsp, the web server calls on the Servlet container to do THOSE jobs.
The Servlet container is the execution environment for a jsp or servlet (they are both servlets) to run Java code on the server and do logic.
So you see, the web server spits out static content, where either no logic is involved, or the client's web browser does the logic. The Servlet container is used for applications that execute code, perform logic, connect to databases, etc.
So they work together, but are completely separate logically.

How is html page outputed when using taglib and xml ?

Dear all,
          I am a newbie for taglib and xml. Today, when I read some source code of a
          website, I found that there is a entry like
          "%@ taglib uri="/tlds/taglib.tld" prefix="myprefix" %>",
          and some other entries like
          "<myprefix:Content area="<%=contentArea%>" />"
          I opened the specifized file taglib.tld and saw a tag entry named "Content",
          its tagclass is com.mycom.presentation.taglib.ContentTag. Again I opend a
          java class file "ContentTag.java" and saw some setXXX methods and doXXX
          methods. I donot know how is the webpage outputed. Can someone give me a
          detailed description about that? I will greatly appreciate your help.
          Some source code segments are listed as follows:
          test.jsp:
          <%@ taglib uri="/tlds/taglib.tld" prefix="myprefix" %>
          <td>
          <myprefix:Content body="<%=body%>" area="<%=contentArea%>"

Hi Andy,
          The sequence of operations that happen when a JSP page encounters a Custome Tag are
          1. Find the class associated with the custom tag from the tld.
          2. The set and get methods that u find are for passing the values for the tag attributes that u may need
          to pass.
          3. The Tag Lib class performs the operation specified and flushes the output to the jsp.
          For further understanding ..u can refer to these sites !!!

Need some help with Slow Downs in Java3D and Servlets

Hi,
I realize that there is a separate forum for Java 3D, but I posted there, and did not get any response. This is kinda the crux of my program, so I would like to invite anybody on this forum with knowledge of Java 3D and servlets to give it a stab. Between this post and that one, there are TWENTY duke dollars up for grabs.
Thanks.
http://forum.java.sun.com/thread.jspa?threadID=603198

Let me have an educated guess.
You calculated the time elapsed before sending in a server request - and at that point you have you updated timeLastStateChange yet, which means by the time of the next calculation of time elapsed this apparent delay is not counted in, hence the slow down in animation rate.
Hope this helps~

Web service and servlets in the same project...web.xml?

Hello, I have a problem with my web service.
I have a server, which displays a web service. I programmed this service with JAXRPC.
I have a client, in another directory. I succeded in compiling, deploying and running the web service.
The problem is that after I tried to integrate this service in an existing project. This project contains servlets. In these servlets, I'm using sessions.
These servlets are on the same side as the server of the web service. Because of the implementation of my code, I'd like to use in the class that represents the server of the service, the same session as the one I'm using in the servlets.
But of course, it's not working by itself. I know there's something to do with the web.xml files.
The thing is that I created a web.xml file for the service, and another for the servlets.
I was thinking of joining both of them in one xml file, but everything crashes then...
Could someone tell me how to create a project with a web service and servlets, and mostly how to configure the xml file??
Thanks for any help

Need help in JSP and Servlets

Hi friends,
[please forgive me if i am posting this in the wrong forum, all seems same to a fresher]
Now, to my problem..i need a suggestion, a way or a method to implement the following!
I am supposed to create a servlet that reads data from oracle database. Once i retrive the data (for example: 6 rows of a table having 4 attributes), i am supposed to pass this data to a JSP page where the data has to be formatted and displayed properly. If i call the same servlet from a different JSP, i should be able to access the data in that JSP and format it in a different way. How do i pass the data to JSP? what method i can use to achieve this task?
Note: I already know about PrintWriter pw = response.getWriter(); and then printing the formated HTML page..but i want to keep the formatting to JSP part and send only the data part that i can access in JSP
Thanks in adavance

How to upload a file into server using j2ee jsp and servlet with bean?

How to upload a file into server using j2ee jsp and servlet with bean? Please give me the reference or url about how to do that. If related to struts is more suitable.
Anyone help me please!

u don't need j2ee and struts to do file uploading. An example is as such
in JSP. u use the <input> file tag like
<input type="file"....>You need a bean to capture the file contents like
class FileUploadObj {
    private FormFile srcFile;
    private byte[] fileContent;
    // all the getter and setter methods
}Then in the servlet, you process the file for uploading
    * The following loads the uploaded binary data into a byte Array.
    FileUploadObj form = new FileUploadObj();
    byte[] byteArr = null;
    if (form.signFile != null) {
        int filesize = form.srcFile.getFileSize();
        byteArr = new byte[filesize];
        ByteArrayInputStream bytein = new ByteArrayInputStream (form.srcFile.getFileData());
        bytein.read(byteArr);
        bytein.close();
        form.setFileContent(byteArr);
    // Write file content using Writer class into the destination file in the server.

Implement SSL in JSP and servlets

hi there,
i needed some help in implementing ssl in JSPs and servlets. My idea was to have a login page and also use it where sensitive data is being sent. I have used the basic socket programming (socket.class and serverSocket.class) in GUI applications using threads to listen and send simultaniously and understand how it works but how do I implement it in JSP and servlets and where do i store the certificate?
i do know that using SSL sockets is very much the same as using the normal sockets.
can anyone tell me any useful links or give me a step by step guide how to implement it and which classes to use
your help would be very much appreciated.
mani

hi,
soory for late reply.
i think you need to use keytool program in your JDK to generate a certificate signature file and you need to configure the server.xml to open and use the HTTPS port. I have not had any additional info on this but i would assume that you simply enter https:// on the file you wish to load in your form and it should use the HTTPS port provided it can find the certificate which must be stored somewhere in your tomcat web server. i would recommend you see tomcat website or search on google for "ssl support in tomcat".i hav not had time to look into this but i will as soon as i am free from my work load.

How to set classpath to EJB and Servlets

Hi all,
How can I add a classpath to EJB and Servlets in Weblogic 6.1, so that that classpath
can be achieved by both EJB jar and war file? I have deployed a .ear file having
the jar and war files. Now the EJBs inside the jar file are not reaching the class
files of the war file and the class files in the war file are not reaching to
the EJBs. Please let me know at the earliest.
Atanu

Hi.
You might try looking at the petstore example which combines webapps (war files) with
ejbs in an ear file to see how to do this. It may be a simple config problem.

Michael

How to setup my computer to run JSP and Servlets

I want to setup my computer to run JSP and Servlets.
What kind of Servers and other tool i need to install to run JSP and Servlets.
Plz, Help me to start my work on JSP.
Regards,
Usman Ali

hello
JSP and servlet is web programming, may be little bit different to development local application.
1st, you should have two computers: one is server and the other is local workstation. This server should have a static IP address, that other people can go into your server. Workstation is any computer normal you use it.
2nd, you need to setup your server in: OS(linux or windows 2000), web server (jrun, apach or Tomcat etc. ), as well as install JDK, servlet.
3rd, your local workstation just use as programming editor and open a browser to testing, anytime you write your code, then ftp to server to test.
Reality, you have many technical thing to solve, eg setup web server etc. However, you can write your source code and test it, then open to outside people.
hope to helpness, if anything don't uderstand, you can post again or send email to me [email protected] Since I just have setup this configuration in my university for my project.

Load balancing for JSPs and servlets

Hi:
          I am using IIS as the proxy server, with the WLS plug-in, to a WLS
          cluster. This provides round robin load balancing just fine. Will it
          provide weight based load balancing if I set 'weblogic.system.weight'
          differently on each server, or is that not relevant for clustering JSPs
          and servlets?
          Sincerely,
          Ashish


Currently the plugins ( for NES, IIS and Apache) just use the round robin
          algorithm. the property
          weblogic.system.weight is used only be weblogic's replica aware clusterable
          RMI/EJB stubs.
          To use this property for your JSP/Servlet load balancing you have to use
          weblogic server as proxy fron-ending your weblogic cluster.
