URLs with a JSP-servlet architecture

I on of my webapp, there is a servlet that forward the request to a JSP. Please tell me why
<form name="theForm" method="GET" action="thPackage.TheClass">works while:
<form name="theForm" method="POST" action="thPackage.TheClass">dont. ???

Could it be because of the you have specified only <http-method>GET</http-method>
but not <http-method>POST</http-method> in the web deployment descriptor web.xml ?

Using JNI with weblogic JSP & Servlets

I want to use native libraries from JSP and Servlets.
          Everything works fine befire redeploying.

Java will not allow us to reload any class that is dependent on a native
          library. I suggest that any classes that depend on native code should be
          put in the system classpath. If you change these classes or the native
          library you will need to restart your server.

URL Rewriting in JSP/Servlets

Enabling URL rewriting for session support where cookies are switched off, results in the URL being rewritten as myURL/$SessionID$a_very_long_string.
I believe that the /$SessionID$ is configurable on the server, does anyone know how ?
OAS version 4.0.8.1. patched with JSP support.

Why is it placing a ';' before jsessionid ? Shouldn't
it be a '&'? The current result is a page not found.Your url looks ok to me. '&' seperates parameters. I'm using the Struts framework to handle those ugly details and it generates urls like this one for me:
http://localhost:8080/JspMini/main.jsp;jsessionid=C2C1C2D9C6106758047127038554C813
Looks like you have another problem...

Hi
I need some help pls
When I use a normal class with a main method, it loads the word document into a blob and I can read this 100%.Stunning.
With a JSP/Servlet I cannot get the document out again. The "format" seems to be lost.

hello,
there are multiple documents out there, describing the oracle reports server setup. try doc.oracle.com for documentation.
also it is part of the online-documentation.
you need to install 9iAS enterprise edition. the server is pre-configured and will listen to the url http://yourserver/dev60cgi/rwcgi60.exe
passing only this url you will get a help-screen, describing the syntax.
regards,
the oracle reports team

Can two urls map to same servlet in web.xml

Hello All,
I need to map the two urls in my web application with the same servlet.
I tried as follows:
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee">
<description>Empty web.xml file for Web Application</description>
<servlet>
<servlet-name>TestServlet</servlet-name>
<servlet-class>fileredirectsolution.TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/testservlet</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/filerepository/*</url-pattern>
</servlet-mapping>
</web-app>
However, I am getting an error while accessing the TestServlet.
When I remove the second servlet-mapping tag..it is working fine.
How can I map the two urls with the same servlet.
Thanks
Saikrishna

it is not ur requirement. but
i think it will help 2 u.
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"; version="2.4"; xmlns="http://java.sun.com/xml/ns/j2ee">
<description>Empty web.xml file for Web Application</description>
<servlet>
<servlet-name>TestServlet</servlet-name>
<servlet-class>fileredirectsolution.TestServlet<;/servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>*.xxx</url-pattern>
</servlet-mapping>
</web-app>
if ur configure web.xml like above.
any request that ends with .xxx call the TestServlet.
ex:
1)http://ip:port/contextpath/abc.xxx
2) http://ip:port/contextpath/xyz.xxx
here both urls calls the same servlet.

Clean URLs with JSP/Servlet

Hello. I've found some information on how to setup clean URLs for php, but none for JSP/servlet. Hopefully some one can help. Here's what I mean by 'clean URL':
http://mydomain/employee.jsp?employeeID=1232
becomes
http://mydomain/employee/1232
And, in that second example, the container would dispatch all requests for /employee* to some JSP/servlet. I don't care if the 'clean URL' has to have an extension or not (e.g. mydomain/employee.jsp/1232) although I would prefer to also remove the JSP extension.
Additionally (if some one has experience with this need): how do I then access the final part of the URL supplied by the client? In other words, how would 1232 be available to the destination JSP/servlet? Does the container convert it into a parameter, i.e.:
1) client sends request for "mydomain/employee/1232"
2) container delegates request to "mydomain/employee.jsp?1232"
Finally (sorry about the length), I don't have access to top-level config files for this site (it's personal use, although I'm pretty familiar with java APIs from my job), so, ideally, I'd like a .htaccess level solution, where the container can just re-route to a JSP.
If any one has some suggestions, I'd GREATLY appreciate it. Thanks for your time. Take care.

...Just occurred to me- this hosting company is NOT using Tomcat. They use resin.
Thanks.

Little help with FORM POST data not in UTF-8 (JSP/servlet)

Hello,
I am trying to update a MySQL database record with UTF-8 characters with my JSP application.
1) I have MySQL correctly configured to handle UTF8 and have tested insert/update/select with UTF8 characters
2) I have an "editRecord.jsp" page. At the top of the page, I specify:
<% request.setCharacterEncoding("UTF-8"); %>
3) I have an input form which is specified in that page which follows:
<form action="<c:url value="/updateRecord.jsp"/>"
name="updatetForm" method="post"
ACCEPT-CHARSET="UTF-8"
enctype="multipart/form-data">
4) I have a servlet filter that takes every HttpServletRequest and modifies that object in
doFilter(...){
request.setCharacterEncoding("UTF-8");
chain.doFilter(...)
5) In updateRecord.jsp, I fill a JavaBean with the form data. Here's an example of the form input:
name = Company
Comments=Here's some unicode text: "يني إن بلاده م
6) When I put a breakpoint and inspect the contents of the UpdateBean after posting the form, running the request through the filter, I see
I see:
name = Company
Comments=Here's some unicode text: ��...."
Where could I possibly be missing something to force UTF8 encoding of these values?

If you have to use the following code to fix the encoding:
String value = new String(item.getString().getBytes("ISO-8859-1"), "UTF-8"); ...
then you are just putting a band aid on something that is broken somewhere else (since this code creates a byte array in 8859-1 and then creates a string from that byte array, but assuming that the array is encoded in UTF-8). That will only work if the string you start out with is mangled.
In many cases such a fix will actually "work" (in the sense that you may end up with something that is correctly encoded in the end), but you run the risk of breaking if the source of the original corruption is removed.

Metadata problem with JSP/servlet application

Hi,
I developed a JSP/servlet test application that makes
use of kodo 2.2.3 STANDARD EDITION for its persitence.
I successfully compile and annotate the application.
I am also able to successfully generate the db
schema with schematool.
Unfortunately, when I run the application using
Resin 2.0.2, Kodo is unable to initialize properly.
Initially it was not able to find "system.prefs" file.
I fixed that by putting "system.prefs" in WEB-INF\classes.
Unfortunately, Kodo is still unable to initialize and
gives the following message:
The system could not initialize; the following registered
persistent types are missing metadata
or have not been enhanced:
[class com.dpov.purchaseorder.PurchaseOrder,
class com.dpov.catalog.Product,
class com.dpov.uidgen.counter.Counter,
class com.dpov.catalog.dao.jdo.CategoryHierarchyEntry,
class com.dpov.catalog.dao.jdo.CategoryHierarchyDAO,
class com.dpov.pricelist.PriceInfo,
class com.dpov.pricelist.PriceList,
class com.dpov.catalog.Category,
class com.dpov.lineitem.LineItem,
class com.dpov.dealer.Dealer,
class com.dpov.user.User,
class com.dpov.customer.Customer].
I use "system.jdo" to describe metadata for the enhancer.
I tried to put it both in WEB-INF\lib and WEB-INF\classes but
it still fails.
Please note that:
1) my classpath variable is not set
2) my application's class file are in WEB-INF\classes
3) kodo jars are in WEB-INF\lib
4) mysql jdbc driver is in WEB-INF\lib
5) system.prefs is in WEB-INF\classes
6) system.jdo is in WEB-INF\classes
Thanks in advance,
Andrea

Hi,
I fixed my problem by setting the system wide variable (WindowsXP)

I fixed that by putting \"system.prefs\" in WEB-INF\\classes.
Unfortunately, Kodo is still unable to initialize and
gives the following message:
The system could not initialize; the following registered
persistent types are missing metadata
or have not been enhanced:
[class com.dpov.purchaseorder.PurchaseOrder,
class com.dpov.catalog.Product,
class com.dpov.uidgen.counter.Counter,
class com.dpov.catalog.dao.jdo.CategoryHierarchyEntry,
class com.dpov.catalog.dao.jdo.CategoryHierarchyDAO,
class com.dpov.pricelist.PriceInfo,
class com.dpov.pricelist.PriceList,
class com.dpov.catalog.Category,
class com.dpov.lineitem.LineItem,
class com.dpov.dealer.Dealer,
class com.dpov.user.User,
class com.dpov.customer.Customer].
I use \"system.jdo\" to describe metadata for the enhancer.
I tried to put it both in WEB-INF\\lib and WEB-INF\\classes but
it still fails.
Please note that:
1) my classpath variable is not set
2) my application\'s class file are in WEB-INF\\classes
3) kodo jars are in WEB-INF\\lib
4) mysql jdbc driver is in WEB-INF\\lib
5) system.prefs is in WEB-INF\\classes
6) system.jdo is in WEB-INF\\classes
Thanks in advance,
Andrea

Problems with file uploading servlet, the form action doesnt capture url

Hi, i have one problem. I am working on a project , i have created a servlet that takes uploaded files and processses them and links them back to user to download. The servlet works perfectly from my computer, I am using apache-tomcat-6.0.16 and java 1.6 , I have two forms called encrypt.html and decrypt.html, I will post both of them, now the problem is when somebody access it on the internet while i am running apache, they get a connection was reset on a firefox browser and same stuff on Internet Explorer.
i have checked my server logs and saw nothing unusual there, So please if you can help me, it is my project.
I am pasting html file and error message that other users where getting remotely.
<html>
<head>
<meta http-equiv='Content-Type' content='text/html; charset=utf-8'>
<title>Stego Form</title>
<link rel='STYLESHEET' type='text/css' href='encrypt.css'>
</head>
<body>
<center>
<form name='encrypt' enctype='multipart/form-data' method='POST' action='http://localhost:8080/examples/temp2
' accept-charset='UTF-8'>
<input type='hidden' name='sfm_form_submitted' value='yes'>
</input>
<input type='hidden' name='eord' value='e'>
<select name='encryption' size='1'>
         <option value='Select an encryption' selected>
         Select an encryption
         </option>
         <option value='DES'>
         DES
         </option>
         <option value='Tripple DES'>
         Tripple DES
         </option>
</select>
         <input type='file' name='overt' size='20'>
         <input type='file' name='covert' size='20'>
         <input type='submit' name='submit' value='Submit'>
</form>
</center>
</body>
</html>so it works for me even if i access the page with my ip , but for others it doesnt work,
now the user got this xhtml page that i will show, i cant find attach button so i am pasting here.
here is the servlet coding

Hi, thank you for your replies, I found out few things about my servlet, and its portability
and i have few questions, although i marked this topic as answered i guess its ok to post
I am using javax.servlet.context.tempdir to store my files in that servletcontext temporary directory. But i dont know how to give hyperlink
of the modified files to the user for them to download the modified files.
What i am using to get the tempdir i will paste
File baseurl = (File)this.getServletContext().getAttribute("javax.servlet.context.tempdir");
System.out.println(baseurl);
baseurl = new File(baseurl.getAbsolutePath()+File.separator+"temp"+File.separator+"files");
baseurl.mkdirs();so i am storing my files in that temp/files folder and the servlet processes them and modifies them, then how to present them as
links to the user for download ?
and as the servlet is multithreaded by nature, if my servlet gets 2 different requests with same file names, i guess one of them will be overwritten
And i want to create unique directory for each request made to the servlet , so file names dont clash.
one another thing is that i want my servlet to be executed by my <form action> only, I dont want the user to simply type url and trigger the servlet
Reply A.S.A.P. please..
Thanks and regards,
Mihir Pandya

New To Iplanet app server.Can some one help me getting started by delpoying and calling one of each of these:JSP,Servlet,EJB.Tried with iplanet docs..didnt quite get it. thanx

Hi,
What is that you are trying to accomplish ? Is it deployment or
trying to develop applications ? Are you getting any errors ? If so,
please post them to help you. I think the documentation is the best place
for you to begin with.
Regards & Happy New Year

You could try doing:
request.getHeader("Referer");

Deploy JSP/Servlet along with EJB

how could deploy EJB with JSP/Servlet?.
First i have
package project.account
1.HomeInterface class
2.RemoteInterface class
3.Bean class
4.Client class
I deployed the above bean in J2EE using Deploytool GUI.
run the client like this
java -classpath %CLASSPATH%;personDepClientClient.jar project.account.Client
it displays result at prompt
what i am asking is
now i wrote JSP file which is kept also this project.account package
i used the JSP file as client for the that bean.
it is Show.jsp file(client file)
<%@ page language="java" %>
<%@ page import="java.util.*" %>
<%@ page import="javax.naming.Context" %>
<%@ page import="javax.naming.InitialContext" %>
<%@ page import="javax.rmi.PortableRemoteObject" %>
<%
     double balance;
try
     Context initi = new InitialContext();
     Object ref = initi.lookup("AccountHome");
     AccountHome home = (AccountHome)javax.rmi.PortableRemoteObject.narrow(ref,AccountHome.class);
     AccountRemote vijay = home.create("200","vijay",0.00);
     vijay.credit(2000.0);
     vijay.debit(600);
     balance = vijay.getBalance();
%>
     <tr>
<td width="38%" height="31">
</td>
<td width="62%" height="31">
<div align="center"><%= balance %></div>
</td>
     </tr>
<%
     AccountRemote kumar = home.create("199", "kumar", 0.00);
     kumar.credit(14000);
     AccountRemote xyz = home.findByPrimaryKey("199");
     xyz.debit(200.00);
     balance = xyz.getBalance();
%>
     <tr>
<td width="38%" height="31">
</td>
<td width="62%" height="31">
<div align="center"><%= balance %></div>
</td>
     </tr>
<%}
catch(Exception ex)
     System.err.println("Caught an exception." );
ex.printStackTrace();
%>
after deployed this JSP file and executed as
http://localhost:8000/project/person/Show.jsp
it displays error as follows
unable to find AccountRemote,AccountHome,findByPrimaryKey
How could deploy JSP along with EJB?.
pls any one tells steps to be followed while Deploying EJB/JSP.
with thanks
vijay

Hmmmm...
ssniazi does nothing but ask for contact information or recommend Oracle products.
Based on this I consider it likely that this person is some sort of sales representative either directly or indirectly associated with Oracle.
I personally wouldn't provide any contact information to this person. Nor would I accept any advice until this person starts to actually provide some solutions or at least correctly reveals any financial interests that they might have.

URL mapping between jsp and servlet

recently, I try glassfish, and I get surprised, for example My application name is HelloWorld if I have jsp action to servlet I can't use action ="servlet/myservlet1" I have to use
action="HelloWorld/myservlet " if I put my servlet2 under test folder I can't call this servlet by servlet/test.servlet2, I have to use HelloWorld/servlet2,. I realize that is not glassfish problem , I just wonder is any one could give more expiration on servlet mapping ??
Thank you !

Depends on several factors. In which context and how exactly are you specifying the URL? In client context, the leading "/" brings you to domain root. In servlet context, the leading "/" brings you to context root. The HTML <a> element is relative to client context and JSTL <c:url> is relative to servlet context. That kind of things.

Determine an URL from an identifier (servlet name, jsp name or something)

I would like to write URLs in my JSP files, but I don't want to hardcode them. Is any way to use the datas from the web.xml?
So I would write the name of the Servlet / name of the JSP file and it would resolve to an URL.
Is any method for this?
Very thanks your help!

The server will load the properties file into memory so there will be some memory overhead. The actual amount of memory used will be server dependent. If you want to make sure the file is loaded just once and the data cached for the entire application set the scope in the fmt:setBundle tag to application. This means the file will be loaded once and stored in memory. The cache will be maintained for the life of the application.
If you want to free memory when the the properties aren't needed, then you can set the scope in the fmt:setBundle tag to page (the default), which will allow (but not force) the memory used by the cache to be released when memory is low.
Note that there are 2 scopes at play here, the properties file is loaded and cached in the resource-loading process so the file would only need to be re-loaded when the data changed. The second is the scope the bundle is stored in for the web application. As long as the web application holds the bundle, the resource cache will not be freed. When the reference is released by the web application the cache may be released if memory requires it, or may be kept so the next time the resource is needed there isn't an overhead related to loading the bundle again.
Setting the scope in the fmt:setBundle to page is the most flexible use, because it allows the Resource cache to hold the properties file in memory then just provide references as needed (much like if you had the scope set to application), but also allows the cache to be free its memory if required.
In the particular example provided above, you don't have control of the Resource Caching. You could implement your own implementation of a ResourceBundle and use ResourceBundle.Control to configure the Cache. This could be done invisibly behind the scenes if you find the memory used by the default implementation too much.

Using jFreeCharts with JSP-Servlet Web App

Can someone please help me to get started on using the jFreeCharts in mt JSP Servlet we app? So far I have this in my servlet but I do not know what to do from here.
protected void doPost(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException {
//          create a dataset...
          double[][] data = new double[][] {
          { 1.0, 4.0, 3.0, 5.0, 5.0, 7.0, 7.0, 8.0 },
          { 5.0, 7.0, 6.0, 8.0, 4.0, 4.0, 2.0, 1.0 },
          { 4.0, 3.0, 2.0, 3.0, 6.0, 3.0, 4.0, 3.0 }
          //DefaultCategoryDataset dataset = new DefaultCategoryDataset(data);
          //return DatasetUtilities.createCategoryDataset("Series ", "Factor ", data);
          CategoryDataset dataset = DatasetUtilities.createCategoryDataset("Series ", "Factor ", data);
          JFreeChart chart = ChartFactory.createBarChart(
     "Bar Chart Demo 2", // chart title
     "Category", // domain axis label
     "Score (%)", // range axis label
     dataset, // data
     PlotOrientation.HORIZONTAL, // orientation
     true, // include legend
     true,
     false
     }

the JFreeChart documentation has examples doing just that.
And if you don't know how to get a browser to call some resource from some html you should get a beginner's tutorial to html.
