Need help in jndi
guys,
i am very new to java and jndi. i am doing a simple jms programs to send a message between 2 clients.
but when i run the programs, it shows the following exceptions.
JNDI API lookup failed: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

can any 1 please clarify me all this exceptions.
Hi
One way to do this would be:
1. Write a sample program which will read the username & password as command line parameters. This will authenticate this data against the LDAP server that you have setup. Once you have this working proceed to step2.
2. Write a Java Bean with two attributes that will hold the username and password. Add a method authenticate user which will contain the code you have written in step 1.
3. Create a JSP with username & password fields. Let the form post to the same JSP or a different JSP/Servlet.
4. In the JSP use the <jsp:useBean> tag to create a bean coded in Step 2. The scope bean should be "request". Set the username and password fields using the <jsp:setProperty> tag. Once you have this , just use the beanId from the <jsp:useBean> tag to call the validation method.
Keep me posted on your progress.
Good Luck!

Need Help in JNDI Datasource using tomcat and spring
Hi,
I am trying to connect my local database using JNDI datasource in tomcat and spring
I have done the below configuration in Tomcat 7 server:
In tomcat server.xml (Path: E:\apache-tomcat-7.0.35\conf) I added the below configuration
<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pathname="conf/tomcat-users.xml" />
<Resource name="jdbc/myApp" auth="Container"
type="javax.sql.DataSource"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:hr@localhost:1521:XE>"
username="testUser" password="password"
maxActive="10" maxIdle="5"
maxWait="60000" removeAbandoned="true"
removeAbandonedTimeout="60" logAbandoned="true"/>
In web.xml, I have added the below config:
<resource-ref>
<description>Oracle Spring JNDI Datasource</description>
<res-ref-name>jdbc/myApp</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
And in my Spring context xml (ws-context.xml), added below config:
<bean name="myDataSourceInJndi" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/myApp"/>
</bean>
<jee:jndi-lookup id="dataSource" jndi-name="/jdbc/myApp" resource-ref="true"/>
In my Java code, I am trying the below code to connect DataBase:
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
DataSource ds = (DataSource) envCtx.lookup("jdbc/myApp");
ds.getConnection();
But I am getting the below exception while executing ****ds.getConnection();***

AdviceHome home = (AdviceHome) PortableRemoteObject.narrow(o,AdviceHome.class);
Advice advisor = home.create();
System.out.println(advisor.getAdvice());
}catch(Exception e){
e.printStackTrace();
and this is the exception i get.

Need help with a simple process with FTP Adapter and File Adapter
I am trying out a simple BPEL process that gets a file in opaque mode from a FTP server using a FTP adapter and writes it to the local file system using a File Adapter. However, the file written is always empty (zero bytes). I then tried out the FTPDebatching sample using the same FTP server JNDI name and this work fine surprisingly. I also verified by looking at the FTP server logs that my process actually does hit the FTP server and seems to list the files based on the filtering condition - but it does not issue any GET or RETR commands to actually get the files. I am suspecting that the problem could be in the Receive, Assign or Invoke activities, but I am not able identify what it is.
I can provide additional info such as the contents of my bpel and wsdl files if needed.
Would appreciate if someone can help me with this at the earliest.
Thanks

thank you -
Need help with applet servlet communication .. not able to get OutputStream
i am facing problem with applet and servlet communication. i need to send few image files from my applet to the servlet to save those images in DB.
i need help with sending image data to my servlet.
below is my sample program which i am trying.
java source code which i am using in my applet ..
public class Test {
public static void main(String argv[]) {
try {
URL serverURL = new URL("http://localhost:8084/uploadApp/TestServlet");
URLConnection connection = serverURL.openConnection();
Intermediate value=new Intermediate();
value.setUserId("user123");
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setDefaultUseCaches(false);
// Specify the content type that we will send binary data
connection.setRequestProperty ("Content-Type", "application/octet-stream");
ObjectOutputStream outputStream = new ObjectOutputStream(connection.getOutputStream());
outputStream.writeObject(value);
outputStream.flush();
outputStream.close();
} catch (MalformedURLException ex) {
System.out.println(ex.getMessage());
} catch (IOException ex) {
System.out.println(ex.getMessage());
}servlet code here ..
public class TestServlet extends HttpServlet {
* Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
System.out.println(" in servlet -----------");
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
ObjectInputStream inputFromApplet = null;
Intermediate aStudent = null;
BufferedReader inTest = null;
try {
// get an input stream from the applet
inputFromApplet = new ObjectInputStream(request.getInputStream());
// read the serialized object data from applet
data = (Intermediate) inputFromApplet.readObject();
System.out.println("userid in servlet -----------"+ data.getUserId());
inputFromApplet.close();
} catch (Exception e) {
e.printStackTrace();
System.err.println("WARNING! filename.path JNDI not found");
} finally {
out.close();
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
System.out.println(" in foGet -----------");
processRequest(request, response);
* Handles the HTTP <code>POST</code> method.
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
System.out.println(" in doPost -----------");
processRequest(request, response);
* Returns a short description of the servlet.
* @return a String containing servlet description
@Override
public String getServletInfo() {
return "Short description";
}// </editor-fold>
}the Intermediate class ..
import java.io.Serializable;
public class Intermediate implements Serializable{
String userId;
public String getUserId() {
return userId;
public void setUserId(String userId) {
this.userId = userId;
}Hi,
well i am not able to get any value from connection.getOutputStream() and i doubt my applet is not able to hit the servlet. could you review my code and tell me if it has some bug somewhere. and more over i want to know how to send multiple file data from applet to servlet . i want some sample or example if possible.
do share if you have any experience of this sort..
Thanks. -
Please, please - i need help urgent.
hi,
i have a problem over 3 days and i cant find what is wrong.
i'm using jbuilder and with him evruthing is ok, but when i want to work with tomcat something going not good and i dont know what.
all the time i'm getting this exception:

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.9 logs.
i checked my database configuration and its seems that it ok(and its run with jbuilder ok).
i need help, please!!!Pray tell me where in teh server.xml/context.xml will you need to >configure a datasource for a simple bridge-driver program as is >obvious from teh stack trace? gcrashed,
When a datasource is used, the connections are retrieved from the datasource. The datasource maintains a pool of connections which can be configured. Programs can retrieve the connections from the datasource and after usage, they are returned to the datasource. Since it is the server that maintains the datasource, properties like connection info, max number of connections etc have to be configured in the server.xml or context.xml
And here is the relevant documentation in tomcat on how to set up a datasource - http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-datasource-examples-howto.html
Setting up a datasource in tomcat requires configuring them in server.xml (for global resources) or in context.xml (for a datasource resource local to your web application).
Here is a thread which describes in detail the process of setting it up - http://forum.java.sun.com/thread.jspa?threadID=643344
Now there are several issues setting up a tomcat datasource, especially for first time users. See the forum thread above for one such discussion.
What configuration is required in tomcat when the stack trace so >clearly shows that he is using the sun.jdbc.odbc.JdbcOdbcDriver and >so obviously using a dsn name for his connection??????As I said earlier, you are missing the point. The OP is not trying to create a connection directly from his program. Or by datasource, he does not mean the microsoft user-dsn datasource that I think you are reffering to. Once again, please read the tomcat link above on what a jndi-jdbc datasource means
Please give me the all 10 different issues that would produce the same stack trace.I was infact hoping somebody would ask. Just type the error stack trace in google, this forum or javaranch or theserverside.com and you would find tons of posts on setting up a jndi datasource and the issues people faced therein.
that's the first and easiest suggestion to give. you don't need to give that suggestion here. Its an open forum. Nobody can tell anybody else on what he/she ought to post. If you dont like it, ignore it. But wait, that's an easy answer. And Iam not going to take that stand. I stick to my opinion that asking the OP to read the docs is still the best suggestion in the post. The OP's problems combined with his comments that the db is working fine suggest a serious lack of understanding of the way datasource and connection pooling works with tomcat.
yes, if the problem is absolutely trivial like: how do i set up a connection using DriverManager - yes u can say - go read the docs. i can swear one can find the answers for half (or many more than that) problems posted in any forum in the documentation. but the fact is that many people do a fair amnount of hunting thru the docs and turn to a forum as a last resort. but they always miss something coz it's very natural. If you would search this forum and analyse duffy's or anybody else( who is a regular in this forum) previous posts, you would find that they have a pretty impeccable record of helping people with genuine problems when they know that the poster has taken some pains or effort to get it going by him/her self. They even hand hold people if the concept is a difficult one or if its one they find stiumlating/challenging.
But this 'unable to set up a datsource' thinggy has been asked and answered a thousand times in this forum and many more in several other forums and all the OP had to do was just search. To be fair, the OP may not have been aware of this fact as he is coming up against this the first time, which's why I maintain, read the docs or search the forum is a suggestion that ought to be taken seriously (rather than being thought of as rude or condescending).
If my comments seemed harsh, i apologize.Make that two. Its not my intention either to brow-beat or be harsh. I am just explaining why I took duffy's side, case in point. No offence intended.
cheers,
ram. -
Need help to develop Pythagoras theorem-
Hi i need help to develop proofs 2,3,4
of pythagoras theorems in java as demonstrations
These are applets can anyone help me with it or give me an idea of how to go about developing it -
the site is the following
http://www.uni-koeln.de/ew-fak/Mathe/Projekte/VisuPro/pythagoras/pythagoras.html
then double click on the screen to make it startPardon my ASCII art, but I've always liked the following, simple, geometric proof:
a b
---------------------------------------+
| | |
a| I | II |
| | |
---------------------------------------+
| | |
| | |
| | |
| | |
| | |
b| IV | III |
| | |
| | |
| | |
| | |
| | |
| | |
---------------------------------------+It almost goes without saying that I+II+III+IV == (a+b)^2, and II == IV == a*b,
I == a*a and III == b*b, showing that (a+b)^2 == a^2+a*b+a*b+b^2.
I hope the following sketch makes sense, stand back, ASCII art alert again: a b
---------------------------------------+
| . VI |
| . . |a
| V . |
| +
| |
| . |
b| . |
| |
| IX |
| . |
| . |b
| |
+ |
| . |
a| . . VII |

a bThe total area equals (a+b)^2 again and equals the sum of the smaller areas:
(a+b)^2 == V+VI+VII+VIII+IX. Let area IX be c^2 for whatever c may be.
V+VII == VI+VIII == a*b, so a^2+b^2+2*ab= c^2+2*a*b; IOW a^2+b^2 == c^2
Given this fundamental result, the others can easily be derived from this one,

Need help to open audios attached in a PDF file
Hello
I just need help. I have ordered a reviewer online that has audios and texts in a pdf file. I was told to download the latest adobe reader on my computer. I have done the same thing on my ipad mini. I am not so technical with regards to these things. Therefore I need help. I can access the audios on my computer but not on my ipad.
I want to listen to audios with scripts or texts on them so i can listen to them when i am on the go. I was also informed that these files should work in any device. How come the audios doesnt work on my ipad.
Please help me on what to do.
ThanksAudio and video are not currently support on Adobe Reader. :-<
You need to buy a PDF reader that supports them. My suggestion is PDF Expert from Readdle ($US 9.99) -

Your Touch is working correctly. Currently, without unsupported third party hacks, the Touch has NO disc mode. It will only show up in iTunes.
how do i put programes and games in my ipod touch
Right now, you don't. The SDK is scheduled to be released in Feburary. Then developers will be able to write programs that will be loadable. -

With that one, let's try the following procedure.
First, head into your Add/Remove programs and uninstall your QuickTime. If it goes, good. If it doesn't, we'll just attend to it when we attend to iTunes.
Next, download and install the Windows Installer CleanUp utility:
Description of the Windows Installer CleanUp Utility
Now launch Windows Installer CleanUp ("Start > All Programs > Windows Install Clean Up"), find any iTunes and/or QuickTime entries in the list of programs in CleanUp, select those entries, and click “remove”.
Next, we'll manually remove any leftover iTunes or QuickTime program files:
(1) Open Local Disk (C:) in Computer or whichever disk programs are installed on.
(2) Open the Program Files folder.
(3) Right-click the iTunes folder and select Delete and choose Yes when asked to confirm the deletion.
(4) Right-click the QuickTime folder and select Delete and choose Yes when asked to confirm the deletion. (Note: This folder may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)
(5) Delete the QuickTime and QuicktimeVR files located in the C:\Windows\system32\ folder. Click Continue if Windows needs confirmation or permission to continue. (Note: These files may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)
(6) Right-click on the Recycle Bin and on the shortcut menu, click Empty Recycle Bin.
(7) Restart your computer.
Now try another iTunes install. Does it go through properly now? -
