UTF-8: JSP to JSP: okay, JSP to servlet to JSP: fail
Hello,
Yes, another guy having problems with UTF-8. I have searched this forum a lot for day, but cannot find a solution that works for me... here it is:
Requests from JSP to JSP work with UTF-8, but only after adding an old-style <% request.setCharacterEncoding("UTF-8"); %> scripting element. Of course, the page has content type text/html with UTF-8 set.
Thus, the result JSP correctly shows UTF-8, e.g. umlauts work then etc.
However, as soon as a servlet is involved, i get data garbage that has nothing to do with wrong fonts etc., per character i get two bytes for special chars.
I tried to set System.setProperty("file.encoding", "UTF-8"), but that does not work also.
The strange thing is that this works on my home Debian GNU/Linux system but not at work on WinNT.
Any ideas?
Here the setup:
J2SE SDK 1.4.1_02
Tomcat 4.1.24
Windows NT 4.0 German
IE 5.0 + Mozilla Firebird 0.7
FYI: the servlet is an inherited Struts class.
Thank you, Timo
Hello MamtzGroove!
You are my hero! I tried all that getBytes() stuff and formatting the sources to UTF-8 etc. and nothing worked. Only when insterting your two statements as is into my servlet, the in works.
The funny thing is that i had used both statements before, but one in the JSP and one in the servlet and vice versa.
THANKS! THANKS! THANKS! Can i give you duke dollars without having created this question with this option?!?!
Greetings + Thanks, Timo
P.S. but why did this work in GNU/Linux? Does it have to do with other System settings????? An idea?

How do I lookup an EJB 3.0 Session bean from servlet or JSP?
Does anyone knows how can I invoke an EJB from a servlet or JSP ?
I deployed a simple EJB on a Oracle Application Server 10g release 10.1.3 and I'm working with JDeveloper 10.1.3. I deployed the files via JDeveloper, and I didn´t specify any orion-ejb-jar.xml or ejb-jar.xml file
After deployment, the orion-ejb-jar.xml look like this in the server:
<?xml version="1.0" encoding="utf-8"?>
<orion-ejb-jar xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/oracleas/schema/orion-ejb-jar-10_0.xsd" deployment-version="10.1.3.0.0" deployment-time="10b49516c8f" schema-major-version="10" schema-minor-version="0" >

<default-method-access>
<security-role-mapping name="<default-ejb-caller-role>" impliesAll="true" />
</default-method-access>
</assembly-descriptor>
</orion-ejb-jar>
I'm trying to invoke the ejb in a servlet by doing the following:
public void doGet(HttpServletRequest request, ....
Context context = new InitialContext();
HolaMundoEJB helloWorld =
(HolaMundoEJB)context.lookup("java:com/env/ejb/HolaMundoEJB");
String respuesta = helloWorld.sayHello("David");
When i invoke the servlet I catch a NamingException whose message says something
like this ....java:com/env/ejb/HolaMundoEJB not found in webLlamaEJB
I tried different paths for the lookup but nothing....
Can anyone help me with this topic? Thank you.Please try the following code:
HelloEJBBean.java:
@Stateless(name="Hello")
@Remote(value={Hello.class})
public class HelloEJBBean implements Hello { ... }
hello.jsp:
Context ctx = new InitialContext();
Hello h = (Hello)ctx.lookup("ejb/Hello");
web.xml:
<ejb-ref>
<ejb-ref-name>ejb/Hello</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<remote>fi.kronodoc.test.model.Hello</remote>
</ejb-ref>
i think you should also define jndi mappings for the references in orion-ejb-jar.xml and orion-web.xml but for some reason it seems to be working also without these. -
Location of java servlet (not jsp) deployed on Java Stack
Hello,
Why this forum? this post is related to the way of calling a java servlet deployed on the java stack, so it's related to the structure of the stack than to real java programming.
Usually, I develop JSP servlets which are easily called either with a mapping or not. I have deployed now a java servlet and added a mapping to it by modifying the xml source itselft in its descriptor, but after deployement I am not able to reach the resource.
In the windows explorer of the java stack I find in j2ee>cluster>server>apps my application as follows:
app_ear>servlet_jsp>app>root>WEB-INF>classes>my class files
app_ear>servlet_jsp>app>root>app.jsp
This time it's not a jsp that I want to call: app/app.jsp but my java servlet which lies in the classes subdir.
Could someone help my to achieve this or is it the wrong way, we can only request jsp applications?
Kind regards,

Blank page while servlet to jsp.
Hi.
am working in a code for login verification.
In my login database i have different user.For each user user access will be different.
So am verifying password for a particular user.The verification is done in servlet page .
After verification am viewing only a blank page.
Can u give me any suggestion.
my code is given below.
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
HttpSession session=request.getSession();
String user="",pass="";
//ServletContext context=null;
ServletContext context=getServletContext();
String userName=request.getParameter("user").trim();
String passWord=request.getParameter("pass").trim();
String query="select * from login where user='"+userName+"' ";
String DbUserName="";
String DbPassword="";
String finalUser="";
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con1=DriverManager.getConnection("jdbc:odbc:register");
Statement stat=con1.createStatement();
ResultSet rst=stat.executeQuery(query);
while(rst.next())
user=rst.getString("user");
pass=rst.getString("pass");
if((userName.equalsIgnoreCase(user))&&(passWord.equalsIgnoreCase(pass)))
session.setAttribute("user",user);
context.getRequestDispatcher("/Mainmenu.jsp").forward(request,response);
else
context.getRequestDispatcher("/LoginError.jsp").forward(request,response);
catch(Exception e){
e.printStackTrace();
}Thanks in advance,
regards,
satheeshkannanIndeed, you are just printing and ignoring the exception instead of throwing it or change the flow.
Apart from this problem: why are you comparing the username once again after the query while the query should only return rows matching the username? Anyway, if your DB is well-designed (i.e. username is unique), then you can also just query for rows matching the username and the password so that you just need to check if ResultSet#next() returns true or not.
Oh, don't forget to use PreparedStatement instead. It will save you from SQL injections. -
URGENT.........File Upload using Servlets and jsp
I am a new servlet programmer.......
iam using tomcat server......
can any one pls help in writing code for file upload using servlets and jsp without using multipart class or any other class like that....
Please URGENT..Slow down! "Urgent" is from your perspective alone. I, myself, am not troubled or worried in the least.
hi ugniss
thanks for ur reply....sorry i was not
y i was not asked not to use multipart class or any
other class like that...is there any other
possibility to do file uploading from jsp to
servlet...
Just as an aside, a JSP is a Servlet. But even if I move beyond that, the question does not make sense. If you want a "JSP to upload to a Servlet", then simply do so in memory. You are still (likely) within the same scope of a given request. However, if instead you are referring to a JSP that is displayed on a browser, then really you are talking about HTML, which is what the browser will receive. And since you are now talking about a browser, your only real, viable option is a multi-part file upload. So, it is either server or it is browser. And either way, the question leads to very established options, as outlined above.
the main concept is.. in the browser the user selects
a particular file and clicks the button upload..after
clicking upload the jsp should sent the file to the
servlet in streams...there the servlet gets in and
saves in a server location........this is wat i hav
to do...
Okay. So, after reading my previous (redundant) paragraph, we have arrived at the crux of the issue. You have a JSP that will be output as HTML to a client (browser) which you want to upload content to your server (handled by a Servlet). So, you are now stuck again with multi-part. The requirement to not use multi-part is non-sensical. You can overcome it, say, if you write your own applet or standalone Swing client. However, if your users are invoking this functionality from a browser, you are limited by the options that W3C has provided you. Use multi-part.
is there aby possibilty to do this.....can any one
pls help....Take the advice to download and review Jakarta Commons FileUpload. Inform your management that their requirement makes no technical sense. Research on your own. There are dozens of examples (and tutorials) on file upload using multi-part. Embrace it. Live it. Love it.

How do I setup in wls 6.1 a jsp file that has a different extension (not *.jsp)
I have a jsp file with extension *.abc. The browser is showing the files as text instead of sending it to be processed as a jsp file.
I have the following settings in the web.xml but it is not picking it up.
<servlet-mapping>
<servlet-name>
jsp
</servlet-name>
<url-pattern>
*.abc
</url-pattern>
</servlet-mapping>
This is kind of a hack and not officially supported, but you might try...
<servlet>
<servlet-name>ABC</servlet-name>
<servlet-class>weblogic.servlet.JSPServlet</servlet-class>
<init-param>
<param-name>compileCommand</param-name>
<param-value>javac</param-value>
</init-param>
<init-param>
<param-name>workingDir</param-name>
<param-value>WEB-INF/classes</param-value>
</init-param>
</servlet>
Since this isn't the default JSPServlet registration, it doesn't pick up the
default JSPServlet init arguments, so after some experimentation I figured
out that you have to at least define these two. Others that you may want to
configure are...
defaultFileName
compileCommand
compilerClass
compileFlags
workingDir
verbose
keepgenerated
precompileContinue
pageCheckSeconds
encoding
packagePrefix
superclass
noTryBlocks
compilerSupportsEncoding
These are all defined as jsp-descriptor args in the weblogic.xml file, but
you can equally use them as servlet-args for your custom JSP registration
Good luck,
Alex
P.S.
Why don't you want to use jsp files anyway?

}Sorry.
actually this is my coding on the bottom.
Pleease disregard my previous coding. I got the different one.
My first approach is using <% %> around the whole doGet method such as:
<%
String[] ids = { "hall001", "hall002" };
setItems(ids);
setTitle("All-Time Best Computer Books");
out.println("<HR>\n</BODY></HTML>");
%>
I am not sure how to break between code between
return;
and
response.setContentType("text/html");
Here is my coding:
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
String[] ids = { "hall001", "hall002" };
setItems(ids);
setTitle("All-Time Best Computer Books");
if (items == null) {
response.sendError(response.SC_NOT_FOUND,
"Missing Items.");
return;
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String docType =
"<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 " +
"Transitional//EN\">\n";
out.println(docType +
"<HTML>\n" +
"<HEAD><TITLE>" + title + "</TITLE></HEAD>\n" +
"<BODY BGCOLOR=\"#FDF5E6\">\n" +
"<H1 ALIGN=\"CENTER\">" + title + "</H1>");
CatalogItem item;
for(int i=0; i<items.length; i++) {
out.println("<HR>");
item = items;
if (item == null) {
out.println("<FONT COLOR=\"RED\">" +
"Unknown item ID " + itemIDs[i] +
"</FONT>");
} else {
out.println();
String formURL =
"/servlet/coreservlets.OrderPage";
formURL = response.encodeURL(formURL);
out.println
("<FORM ACTION=\"" + formURL + "\">\n" +
"<INPUT TYPE=\"HIDDEN\" NAME=\"itemID\" " +
" VALUE=\"" + item.getItemID() + "\">\n" +
"<H2>" + item.getShortDescription() +
" ($" + item.getCost() + ")</H2>\n" +
item.getLongDescription() + "\n" +
"<P>\n<CENTER>\n" +
"<INPUT TYPE=\"SUBMIT\" " +

Error in accessing servlet from JSP
Hello everybody,
When I access a servlet from a JSP page,I am getting the following error message :
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.
I am using Weblogic 7.0 and my web.xml code is as follows:
<web-app>
<servlet>
<servlet-name>TestServlet</servlet-name>
<servlet-class>TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/TestServlet</url-pattern>
</servlet-mapping>
</web-app>
I am accessing the servlet from a javascript function in my JSP page.
I am quite new to the Java technology. So any help in this regard would be highly appreciated.
Thanks in advance,The form action event is in a javascript function. I am sorry I mentioned that I am accessing this servlet from JSP. Actually,this servlet is accessed from an HTML document.
The following is the javascript code:
<script language="javascript">
function lfnCallNext()
alert("In the function");
frmMain.method="POST";
frmMain.action="/TestServlet";
frmMain.hidChoice.value="GetList";
frmMain.submit();
</script>
And this function is called from an hyperlink as follows:

Change protocol when redirecting a request for a servlet to jsp
Hello,
In my servlet, There is a line of code:
getServletConfig().getServletContext().getRequestDispatcher("/page.jsp").forward(request,response);
My question is: I'd like to change the current protocol (like http) to new protocol (like https) or versa vista before my servlet executes the above line.
Is this possible to implement that? If so, how can I do it?
If not implement, Is there any ways to convert back or forward between http and https protocols in java, servlet or jsp?
I did try to use window.location.href="protocol://myserver/..." in javascript to redirect the jsp page to the right protocol, but the session for the browser was lost, and the jsp page ran into infinite loop.
Thanks in advance for any helps.
Mike.if (!request.isSecure()) response.sendRedirect("https://me.com/page.jsp");
(or visa versa) -
In Dreamweaver MySites[New Site] menu option , if I had a hosting JSP/PHP what I must declare the hosting JSP or PHP ?
The simplest answer is to choose the language you work best with, and that fits the clients specification the best.
I have mixed server languages on a site before, (would not recommend) when a client has decided they wish to change from their old one to a new(er) /different one, the only thing you must watch if doing this, is that you do not mix languages on the same page (will not work correctly, if at all), and parameter passing.
