  • Pls. help me out..Accessing ejb through jsp

    hi all,
    I am running my ejb on the j2sdkee.1.2.1 and jdk1.3 on Windows 2000. I am facing a problem while accessing the ejb from the jsp page. Its running fine when accessing through a client application. The following is the error when I try to access it using:

  • How can I access EJB  through executable jar file?

    Hello buddies!!
    I wonder if anyone could give me an explanation of how accessing EJB through executable jar file?Thanks!!

    Hi there,
    You'll need to install the J2EE SDK on the client and include the <j2ee install dir>\lib\j2ee.jar file in your CLASSPATH along with the Client Jar file that was generated by the deploytool when you deployed the application.
    In your client code the Context properties are as follows:
    Properties p = new Properties();
    p.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
    p.put(Context.PROVIDER_URL, "iiop://hostname:portnumber");
    Context cntx = new InitialContext(p).Hope this helps

  • Column Not found error while trying to access databse through JSP+Java Bean

    I am trying to acees MS Access 2003 db through JSP using Tomcat 5.0.28.The code for accessing the databse is incorporated in the bean.The jsp only calls the particular method of the bean .
    Code for Java Bean:

    Can someone please help me with their precious advice?

    U're getting this error because there is no field called 'password' in ur database, the field in ur database is named 'cpassword' and not 'password'. So change the statement rs.getString("password"); to rs.getString("cpassword");

    Hi, I too have a problem with an SQL exception, the message is Column not found.
    I'm using the sun jdbc odbc driver with access.
    the first few lines of the stack trace are
    sun.jdbc.odbc.JdbcOdbcResultSet.findColumn(JdbcOdbcResultSet.java:1852)
    sun.jdbc.odbc.JdbcOdbcResultSet.getInt(JdbcOdbcResultSet.java:603)

    sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
    I am of course sure that the column does infact exist. I can insert into the column no problems. the sql looks like this:
    SELECT * FROM Members WHERE uName ='Stewart' AND encPwd='�F2C�3����h�1Y�'
    Can any one tell me if there is a common cause to this problem?
    Thanks

  • How to access dataprovider through jsp syntax

    I am creating an image gallery but here's my issue...
    I have a database table that contains links to images on my file system. I created a dataprovider for this database table on my page so the dataprovider now returns all the image links.
    Now what I need to do is create a row of thumbnails so I add a scriptlet in my jsp code where I want the thumbnail to appear. This scriptlet loops through the dataprovider and for each row it will create a standard html image tag populating the src attribute with the link from the dataprovider.
    I figure creating dynamic html img tags is much easier than creating dynamic image components in the backing bean. Doing the former allows me to output the row of thumbnails exactly where I want them on the page (ie where i put my scriptlet code) and is easier to manage.
    The problem is i don't know how to access the dataprovider through jsp tags and syntax. I'm sure there must be a way, can anyone help?
    Thanks.

    I've done this sometimes using scriplets:
    <%
        request.setAttribute("SOME_CONST", Constants.SOME_CONST);
    %>
    <c:out value="${SOME_CONST}" />But I would also be interested if anyone knows a way without those ugly scriplet..

  • Accessing EJBs through LCES2 SDK Service Forms

    Hello,
    I try to use this sample (here) to create a Forms Service access from a servlet but I  find "ALC-DSC-031-000: com.adobe.idp.dsc.net.DSCNamingException: Failed to search remote  EJBObject for the supplier dejb / call.
    I did a default installation of LiveCycle ES2 (JBoss, MySQL).
    I use Glassfish 3 to create the site using the service Forms through a servlet.
    I observed that execption is thrown when using the service renderPDFForm by formsClient.
    I wonder if the problem is with the port 1099 for DSC_DEFAULT_EJB_ENDPOINT.
    But I do not know whether this port works and if the problem actually comes from.
    Can you help me ?

    I slightly modified the code :
    String fileName = "rideau1.jpg";
    File oneImg = new File("C:\\" + fileName);
    FileInputStream fileAttachment = new FileInputStream(oneImg);Document attachment1 = new Document(fileAttachment);
    Map<String, Document> fileAttachments = new HashMap<String, Document>();
    fileAttachments.put(fileName, attachment1);
    I'm sure image exists, file exists but attachement1 is empty...
    oneImg getPath : C:\rideau1.jpg
    fileAttachments : {rideau1.jpg=}
    fileAttachment available : 15872
    But normally I'm able to null in function renderPDFForm as fileAttachements...
    The problem can be put there by URLSpec ?

  • Accessing pdfs through jsp content tags from content server!!!!!

    hi,
    i have uploaded few images in content server which i can access by dis syntax
    <ad:adTarget query="adAltText='intraday'" height="200" width="200"/>
    or
    <ad:adTarget query="image_name=='first'"/>
    but for accessing pdfs..
    <ad:adTarget query="title=='InsuranceDataSheet'"/><br>
    dis syntax doesnt work..it only provides me a link on the jsp page on click of which i can go to that pdf..
    what should i change?
    kindly help..

    By default, only image and text content have configured renderers for <ad:adTarget>, <ad:render>, and <ph:placeholder>; for all others, it does just print a link, as you're seeing. However, you can write and configure additional content renderer classes for other mime types (e.g. appliation/pdf). See http://download.oracle.com/docs/cd/E15919_01/wlp.1032/e14238/placeholders.htm#i1006120 for details.

    Thanks, Kristjan
    THIS IS THE JSP: (useejb.jsp)

    import javax.ejb.CreateException;
    public interface MySessionEJBHome extends EJBHome
    public MySessionEJB create() throws RemoteException, CreateException;
    }

    You might want to look at using a Java Bean wrapper, this can be done automically using WebSphere. It creates what is called an access bean which the JSP imports.

  • Caonnecting ms access database through tomcat5.5 query

    Hi,
    I have installed tomcat5.5 and jdk1.6 on my machine which has Windows server2003 as OS.
    I'm not able to clearly underdstand the steps in tomcat docs for connecting to database and the changes to be made in different files.
    Can someone tell me detailed and clear steps for connecting to an ms access database through jsp?
    Thanks in advance for your suggestions.

    I'm not exactly sure why you have this problem. I know that the Microsoft SQL Server driver has a parameter "readOnly=false". Check your DB2 docs to see if you need to set a flag like that, too.
    Maybe it has to do with transactions and auto commit. See if DB2 assumes autoCommit true or false. Maybe you have to explicitly commit your INSERT.
    Maybe you're writing to one database and opening another. Make sure that's correct.
    There are other suggestions that I'll offer.
    You do all that work with a database in a constructor? Bad idea.
    You've got database and UI stuff all mingled together. Ever heard of MVC separation?
    Be object-oriented - start by designing an object to encapsulate all those items you're trying to INSERT.
    Then write a Data Access Object (DAO) that does CRUD operations for that object. Test these thoroughly, preferrably with JUnit, until they're 100% perfect.
    Then have a separate UI that instantiates these objects and calls their methods. The persistence layer shouldn't know about UI stuff, and the UI shouldn't need to have any persistence code in it.

  • Security exception while trying to access EJB from stand alone client

    Hi!, I am trying a sample EJB application to R&D some security related issues. I want to access EJB through a web application as well as a stand-alone client. I have set approriate <method-permission> in EJB deployment descriptor. I am using users.properties/roles.properties file for authentication mechanism. I am using JBoss 3.2.
    - On the web application side I am using BASIC authentication and the servlet is able to access the EJB OK, as long as I am using a login/password that has access to the EJB.
    - Now I am trying to access the EJB using a stand alone Java class. These are the things I have tried till now:
    =>Created a InitialContext with appropriate principal, credentials and tried getting a reference to EJB home interface. That resulted in security exception.
    =>Logged into a LoginContext by using appropriate JBossSX classes and then tried getting a EJB home interface. Again security exception.
    Now I am not sure what to do. I read at some places about client side container but not sure what that is. Does anyone has any ideas to try? Is there any other way I can make a swing application and a web application authenticate to EJB container?
    Also can anyone point me to any documentation that gives some idea about how the security credentials gets propagated from web application/standalone client to EJB container?

    It would be better if you can post your code...and DD that way we can help you better

  • EJBs From JSPs - Tutorials?

    Hi all,
    I've just been given a task, and I don't know where to start. I've been given an EJB and I need to write a web front end to test it (JSP). Now if it was a plain JavaBean, I know how to do it. But I know EJB's are different.
    Could somebody point me in the direction of a good tutorial about accessing EJBs from JSPs. I'm using WebLogic as my application server, so something relevant to that would be nice.
    Cheers for any help.

    To put it in "idiot" terms:
    Think of your EJBs as people you want to ring up on the phone. You know their name, but not their number. How do you do this in real life? You use a phone book, using the person's name as a reference, which will lead you to the right number to dial.
    The phonebook in this paradigm is JNDI - the naming and directory interfaces.
    The name you use to look up is how the EJB is bound (ie, "java:comp/env/ejb/MyPerson", or "foo/bar/beans/MyPerson"). You define this name (the phone number) in the deployment descriptors packaged with the EJBs in the jar file.
    You access the phone book (in your JSP or some other bean in your webapp) by using a Context.
    ie:
    Object objRef = initialContext.lookup("foo/bar/beans/MyPerson");
    Then you ask the context for the person's home information:
    MyPersonHome home = (com.foo.interfaces.MyPersonHome)PortableRemoteObject.narrow(objRef, com.foo.interfaces.MyPersonHome.class);
    Once you know where they live (you have their Home information), you can ring them up (create them, search for them, search for a singular one)
    MyPerson bill = home.findByPersonNameInHouse("billy");
    once you have Billy in your possession, yu can perform business logic on him:
    String stats = bill.getStatistics();
    // get rid of bill permanently
    bill.remove();
    That should be enough of an introductory paradigm. You will need to follow along the tutorials and other many documents to understand exactly how things are bound (phone numbers are listed) and so forth.
    Good luck!

    For installing JSTL, all you need are the jar files in the web-inf/lib directory.
    - No entries in web.xml
    - no tld files lying around
    - no problems!
    I think you may have a versioning problem here.
    What version of Tomcat are you using?
    With JSP1.2 (eg Tomcat 4), you should be using JSTL1.0. <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
    With JSP2.0 (eg Tomcat 5), you should use JSTL1.1. <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
    Note the difference in the URIs. - the second one includes a /jsp
    Currently you are using the URI for JSTL1.0, but you look to have the tld from JSTL1.1. If you are using a JSP1.2 container, I don't think it could read this tld file, hence the error.
    Try installing the correct version of JSTL, properly (ie as they tell you in the readme file) and it should all work.

  • Tunneling vs. Web Service to access EJB's through firewall

    I need to be able to access EJB's from a client application when the server is
    behind a firewall. Seems like I have two options:
    1) Use WebLogic's built-in http-tunneling support.
    2) Use WebLogic to generate a web service for each bean and then modify the client
    application to use the generated SOAP stubs instead of having direct EJB references.
    Now I know either option will result in slower performance as compared to direct
    EJB references, but I'm not sure which is worse. Has BEA done any comparison
    of the two approaches to know which one is expected to perform better than the
    other? Any guidence someone can provide is greatly appreciated.
    thanks,
    Dan

    If performance is your primary concern that it would be best to
    benchmark both. I suspect the performance difference will greatly
    depend on what types you are marshalling.Yep, I was curious about the same thing and tried some benchmarking - depending
    on what was marshalled, or course, SOAP performance hit vs binary protocol was
    not as bad as i expected it to be.
    However, a web service client would offer some nice advantages. Your
    client application would be a lot more flexible.But there will be some functionality loss over RMI.
