Creating initial context from a java client

I have tried to create intial context from a java client.....
but that gives me the following exception:
My code:TestClient.java

public class TestClient

Context ctx = new InitialContext(hash);
System.out.println("Context: "+ctx);
The output is:

is anybody able to solve my problem....
Thanks in advance..

Nilesh,
First of all make sure that the shared library error you are getting is fixed by including the library in your classpath. Secondly, where are you running the client from? The connection factory that you use varies depending on where you are connecting from:
1. ApplicationClientContextFactory is used when looking up remote objects from standalone application clients. This uses refs and mappings in application-client.xml.
2. RMInitialContextFactory is used when looking up remote objects between different containers.
3. ApplicationInitalContextFactory is used when looking up remote objects in same application. This is the default initial context factory and this uses refs/mappings in web.xml and ejb-jar.xml.

Oracle Hello Rob cole..
thank u for ur reply...but actualy i dont know what is application-client.xml and where i can find that file in my j2ee folder...can u give me detail explanation about that...actually i have not created any application or not deployed also without deploying any application i have created that TestClient.java class so how it will relate with application-client.xml....so i have changed the lookup code with ApplicaitonClientContextFactory...but still the same error is coming......can u give me the full explanation or solution of my problem...
Thanks & Regards

Converting string(which is an xml from the java side) to xml in flex

Hi,
   I have an xml from the java side which i send as string over amf. I need to convert this to xmllist or xml and bind it to a tree. Could some one help me in doing this. My label field needs to be displayName
this is my xml that comes as string to the flex side
<Menu>
<MenuItem>
    <id>1</id>
    <displayName>Add</displayName>
    <menuList>
      <MenuItem>
        <id>3</id>
        <displayName>Form1</displayName>
        <menuList/>
      </MenuItem>
      <MenuItem>
        <id>4</id>
        <displayName>Form2</displayName>
        <menuList/>
      </MenuItem>
    </menuList>
</MenuItem>
<MenuItem>
    <id>2</id>
    <displayName>Delete</displayName>
    <menuList>
      <MenuItem>
        <id>5</id>
        <displayName>Form1</displayName>
        <menuList/>
      </MenuItem>
      <MenuItem>
        <id>6</id>
        <displayName>Form2</displayName>
        <menuList/>
      </MenuItem>
    </menuList>
</MenuItem>
</Menu>

Well, for Binding you will probably need to further convert to XMLListCollection or ArrayCollection.
Not sure.
However, that is the way to convert String to XML.

How to get an XML string from a Java Bean without wrting to a file first ?

I know we can save a Java Bean to an XML file with XMLEncoder and then read it back with XMLDecoder.
But how can I get an XML string of a Java Bean without writing to a file first ?
For instance :
My_Class A_Class = new My_Class("a",1,2,"Z", ...);
String XML_String_Of_The_Class = an XML representation of A_Class ?
Of course I can save it to a file with XMLEncoder, and read it in using XMLDecoder, then delete the file, I wonder if it is possible to skip all that and get the XML string directly ?
Frank

I think so too, but I am trying to send the object to a servlet as shown below, since I don't know how to send an object to a servlet, I can only turn it into a string and reconstruct it back to an object on the server side after receiving it :
import java.io.*;
import java.net.*;
import java.util.*;
class Servlet_Message        // Send a message to an HTTP servlet. The protocol is a GET or POST request with a URLEncoded string holding the arguments sent as name=value pairs.
public static int GET=0;
public static int POST=1;
private URL servlet;
// the URL of the servlet to send messages to
public Servlet_Message(URL servlet) { this.servlet=servlet; }
public String sendMessage(Properties args) throws IOException { return sendMessage(args,POST); }
// Send the request. Return the input stream with the response if the request succeeds.
// @param args the arguments to send to the servlet
// @param method GET or POST
// @exception IOException if error sending request
// @return the response from the servlet to this message
public String sendMessage(Properties args,int method) throws IOException
    String Input_Line;
    StringBuffer Result_Buf=new StringBuffer();
    // Set this up any way you want -- POST can be used for all calls, but request headers
    // cannot be set in JDK 1.0.2 so the query string still must be used to pass arguments.
    if (method==GET)
      URL url=new URL(servlet.toExternalForm()+"?"+toEncodedString(args));
      BufferedReader in=new BufferedReader(new InputStreamReader(url.openStream()));
      while ((Input_Line=in.readLine()) != null) Result_Buf.append(Input_Line+"\n");
    else
      URLConnection conn=servlet.openConnection();
      conn.setDoInput(true);
      conn.setDoOutput(true);
      conn.setUseCaches(false);
      // Work around a Netscape bug
      conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
      // POST the request data (html form encoded)
      DataOutputStream out=new DataOutputStream(conn.getOutputStream());
      if (args!=null && args.size()>0)
        out.writeBytes(toEncodedString(args));
//        System.out.println("ServletMessage args: "+args);
//        System.out.println("ServletMessage toEncString args: "+toEncodedString(args));
      BufferedReader in=new BufferedReader(new InputStreamReader(conn.getInputStream()));
      while ((Input_Line=in.readLine()) != null) Result_Buf.append(Input_Line+"\n");
      out.flush();
      out.close(); // ESSENTIAL for this to work!
    return Result_Buf.toString();               // Read the POST response data
// Encode the arguments in the property set as a URL-encoded string. Multiple name=value pairs are separated by ampersands.
// @return the URLEncoded string with name=value pairs
public String toEncodedString(Properties args)
    StringBuffer sb=new StringBuffer();
    if (args!=null)
      String sep="";
      Enumeration names=args.propertyNames();
      while (names.hasMoreElements())
        String name=(String)names.nextElement();
        try { sb.append(sep+URLEncoder.encode(name,"UTF-8")+"="+URLEncoder.encode(args.getProperty(name),"UTF-8")); }
//        try { sb.append(sep+URLEncoder.encode(name,"UTF-16")+"="+URLEncoder.encode(args.getProperty(name),"UTF-16")); }
        catch (UnsupportedEncodingException e) { System.out.println(e); }
        sep="&";
    return sb.toString();
}As shown above the servlet need to encode a string.
Now my question becomes :
<1> Is it possible to send an object to a servlet, if so how ? And at the receiving end how to get it back to an object ?
<2> If it can't be done, how can I be sure to encode the string in the right format to send it over to the servlet ?

Accessing RFCs and BAPIs from enterprise java beans

Hello folks,
     my question is concerning comunication between EJBs and RFCs. I want to develop a simple session bean that connects to a R/3 back-end, calls a RFC then returns some data, let's say, an example of this could be a list of employees from BAPI_EMPLOYEE_GETDATA.
     Ok, by using a web dynpro and adaptive RFC my works could be very very easy, but I'd like to test this way: session (stateless) EJB -> RFC. Can I:
*     use JCO.ClientService with a non-portal SAP WAS?
*     use embedded JRA (SAP Library stated "The SAP JRA is an add-on for the SAP JCo. If you use      the SAP Web AS, the SAP JRA is installed automatically with the SAP JCo.", but I found      nothing so in Connector Container Service ...)
*     install and configure JRA by myself?
I'm working on a SAP WAS 6.40 Sneak Preview (Java only), and finding a path for easily integrate SAP WAS developed ejbs and external business system. SAP Library suggest to "obtain the JCo connection through the connection framework": is it related to JRA, JCA and SAP Resource Adapter?
Thank you

to use jra inside j2ee first deploy the connector with the settings you need and then get a connection to it using jndi

How to create an xml from xsd in abap

HI Experts,
i want to create an xml file from xsd and i want to validate an xml file against an xds.is this possible in abap.if it is possible can any one give me an sample code
for this one.
how to create an xml file in abap.i have seen so many blogs which parses the xml file but i didn't get blog for creating an xml file.how can we do that one.
any suggestions will be appriciated
thanks in advance
With Regards

HI
GOOD
IT IS POSSIBLE IN ABAP
Extensible Markup Language (XML) is a simple, very flexible text format derived from SGML (ISO 8879). Originally designed to meet the challenges of large-scale electronic publishing, XML is also playing an increasingly important role in the exchange of a wide variety of data on the Web and elsewhere.
XSD->
XML Schemas express shared vocabularies and allow machines to carry out rules made by people. They provide a means for defining the structure, content and semantics of XML documents. in more detail.
XDS->
XDS can process data images from CCD-, imaging-plate, and multiwire-detectors in a variety of formats. Detector specific Input file templates greatly simplify the use of XDS; they are provided as part of the documentation.
XDS runs under Unix or Linux on a single server or a grid of up to 99 machines of the same type managed by the MOSIX system; in addition, by using OpenMP, it can be executed in parallel on up to 32 processors at each node that share the same address space.

Parsing XML from a session bean

Hi,
I am trying to use a Sax parser for parsing xml received from a back end
legacy system. The code is executed from a Session bean.
Debugging learned me that the parse() method on the parser hangs the
container without any error or exception trace. The code works fine outside
a container.
All help will be highly appreciated.
Kurt

I found out that the InputStream implementation used parsing source inside
the container is different
then from the one outside (other type of VM of course!). The Weblogic
implementation blocks at the end of
the stream, while the normal SUN JDK 1.3 returns. This is not a bug, the bug
I found is in my proxy that allows
the connection to the backend. This proxy allows HTTP connections, and I
parse the XML received over HTTP.

Kurt

That's seems odd. Perhaps there is something going on in your document
handler code that triggers a hang in the environment of the server.
When you see the hang, instruct the VM to give you a thread dump (type
control-<break> on Windows, <control>-\ (backslash) on UNIX in the
window in which the server is running; the results are dumped to
stderr). That will show what every thread in the server is doing. If you
email or post the thread dump, I will take a look at it and see if I can
see what is going on. Also, let us know which platform, VM, parser, and
WebLogic version you are using.

Accessing an URL from Forms Java Bean

Dear Oracle Gurus,
Please help me
I have an Oracle Application Server 10g Rel1 in production. I have oracle forms running with a java bean. I am passing an URL to this java bean to fetch and display an image.
This url belongs to another web server (IIS server running a ASP.net application). If i call this url in internet explorer window it is displaying the image. If the same URL if i am calling from forms applet it is not working. When i checked in the java console by setting up trace level to 5 no error message.
I have checked in the midtier/j2ee/home/log/home_default_island_1 folder in the log file no error messages. I have setup the internet explorer --> internet options --> security --> custom level --> miscellaneous --> access data across domain --> enable.
Please give me a solution.
Best Regards
Syed Jalal

Hello,
I don't know how we can help you, because you use a Java Bean and did not tell us anything about this bean. A bean is like a "black box", so we cannot give you any help at all without the code.

Any thoughts?

Hi Richard,
Not sure, if i got it correctly.
You are talking abt the element name ?
then, always give meaningful short name to columns in the query.

How to call the method from the java bean and pass it to JSP textbox

i'm quite new to java thats why i'm asking how to call a method in the java bean file and pass it to the JSP textbox. My projects are communicating JSP with C#. i had successfully created a C# client bean file for JSP. The whole process is to type something on the server(C# programming) and it would appear in the textbox.

your question doesn't provide much informartion. provide some other information and coding so that we could tell exactly what you are looking for?

How to create nested xml tags using java parser?

Hi,
I need to create a xml file containing following tags using java program-
<A attr1="abc">
<B attr2="xyz">
<C attr3="pqr"> </C>
</B>
</A>
Can anyone please let me know which parser should I use to create the above mentioned xml file?
If possible, please post a code snippet for the same.
Thanks in advance..

Well, you could start by doing it all the 'old fashioned' way; create a String object containing that text and then write it away to a file. Or you could take the time to look at the javadoc for all of the xml support that the Java language itself supplies - XMLReader/Writer for a start. After that put together some code that you think would do the job and ask for help on any specific problems you encounter.

Creating a file from a Java Program

Hi all,
if I want to store a byte array to a file somewhere in the middle of my program... is it possible to create the file inside my Java program, i.e. the file will be created during the execution of my program, and then write this byte array into it? The name of the file to be created is predefined by me, and not thru user input.
If so, does anyone have a sample source code to show me? or redirect me to somewhere ?
Thanks in advance!
Joe

You can take a look at the File, FileOutputStream, FileInputStream classes. A simple one will be like:
byte[] ar = {12,13,14};
File file = new File("wee.dat");
if (!file.exists())
try
FileOutputStream fos = new FileOutputStream(file);
fos.write(ar);
}catch (IOException io){}
else

Dynamic JSP's includes from JSF Java Beans

Hi!
I�m David from Barcelona.I'm testing different JSF components.
I'm working with MyFaces components, with Tabs, binding the component like this to create sub tabs dynamically:
<t:panelTabbedPane binding="#{editorPanelBean.pane}"/>
Now, in the bean, I use the Application class to create
my pane and child tabs:
UIComponent pane = app.createComponent(TABBEDPANE);
UIComponent childtab = app.createComponent(PANELTAB);
HtmlPanelTab tab = (HtmlPanelTab) childtab;
I want to start adding contents to my child tabs.
Am I locked into doing it programmatically or is it possible to somehow refer back to a JSP page
with an include to generate the contents of each tab child?
I can do it without binding the panelTabbedPane component, but the problem it's when I construct the component with a binding, then the include JSP doesn't work. I have tried with a Verbatim and HtmlOutputText but no results, like this:
HtmlTabItem aHtmlTabItem = (HtmlTabItem) application.createComponent(HtmlTabItem.COMPONENT_TYPE);
aHtmlTabItem.setValue(valor);
aHtmlTabItem.setId(viewRoot.createUniqueId());
UIOutput verbatim1 = (UIOutput) application.createComponent("javax.faces.Output");
//verbatim1.setValue("<f:subview id=\""+viewRoot.createUniqueId()+"\"><jsp:include page=\"ficha_paciente_tab2.jsp\" flush=\"false\"/></f:subview>");
verbatim1.setValue("<%@ include file=\"ficha_paciente_tab2.jsp\" %>");
verbatim1.getAttributes().put("escape", Boolean.FALSE);
verbatim1.setId(viewRoot.createUniqueId());
aHtmlTabItem.getChildren().add(verbatim1);
How can I include dynamically from my bean a JSP page with the HTMlL design of each tab and anything I want to ?
Any help would be great !
Thanks!

1. username and password should be simple String properties, don't make it any more difficult than it needs to be.
2. if (result == "success")
Oh dear, Java 101 mistake. You want to use result.equals("success") to make that work.
Another observation: you may want to move all the database code to a separate class. If you put database logic in seperate classes with specific methods (login(), logout(), getAllUsers(), etc.) you not only make your code more readable but you make it possible to re-use those methods in different parts of your code.
