Memory and java beans

i have servlet that creates a bean that holds some data from a table.
Purpose: not to hit DB2 everytime to build some drop downs on jsp.
We just wanted to have a bean in the memory and access it whenever we need it.
Now, my concern is server memory.
Can someone tell me how does java data beans effect memory?
My java bean holds only plain text from the table.
I think there are over 1300 records. is it worth doing this?
Is there a guide that tells me for how many rows how many MB of ram is used?
thanks
nn

Well you need not worry much about memory as this will be taken care by the Container i.e. EJB Server in general
The EJB Server will serialize the object in the file if it is not used for a certain period of time and again deserialize when the file is used
Bye for now

  • Create XML dynamically from schema and Java bean

    Hi,
    I'm looking for suggestions on the best approach to create an XML file programatically from a schema and Java bean.
    The schema used is not fixed and may vary with each request so a dynamic way to create the XML is required.
    Is there an API available that allows me to achieve this easily? Any help would be appreciated to point me in the right direction.
    Thanks.

    XMLBeans or JAXB should work for you.

    Ok, this seems to be a long and convoluted path to do absolutely nothing.
    You submit the form.
    You run a servlet that gets the parameters correctly (good), creates a SimpleBean (good) and then sets this into request attribute space under the names "user" and "pass" - (why?)
    You then forward to the jsp: submit.jsp.
    Submit.jsp creates a new SimpleBean, and attempts to populate it with <jsp:setProperty>. You then call the issueData method on it.
    Your complaint: Rows are being created in the database which have empty string values instead of the parameters you have passed.
    So, why are the values blank? Where do you think these values should be coming from?
    Looking at SimpleBean we find one mistake - you have mis-named your get/set methods.
    To properly follow java beans standards, you should use camel-case for your methods.
    Rather than getuserName() the method should be getUserName(). getpassword() should be getPassword() etc etc.
    The method getUserName() defines a property "userName" for the bean.
    Once that is fixed, lets go to submit.jsp. The <jsp:setProperty> statement will try and set all properties of the bean from the request parameters.
    There are no request parameters "userName" or "password" so those values don't get set in the bean, therefore it uses their default value of empty string - "".
    There ARE request parameters called "user" and "pass" but because they aren't properties of the bean, they get ignored.
    As a result, the values are empty string, and that is exactly what gets inserted into the database.
    Ways to fix this
    1 - rename your parameters on your form to be "userName" and "password" to match the bean. That way the <jsp:setProperty> tag will populate them properly.
    or
    2 - Call issueData() method from your servlet after you have created the SimpleBean. Better in my opinion as you then don't have any scriptlet code on a JSP page.
    Cheers,

  • Forms 6i and Java Bean

    Hi
    I need to establish communication between my forms and java code.
    i have made a java bean and set the implementation class path(i.e the package path (oracle.forms.demo for the bean class)) in the form item.
    I want to know where exactly should put the java code or do i have to make modification in any of the environment variables to allow the forms to acces the java code.
    what exactly is a java class and do i need to have a wrapper class also to implement the java bean.
    please respond fast as i need this info urgently...any small info might prove fruitful
    Thanks

    Hello,
    All you have to do is to copy the .jar file that contains the Java class(es) in the <devsuite>/forms/java/ directory, configur the <devsuite>/forms/server/formsweb.cfg file to add this jar file to the archive_jini tag to indicate where Forms have to load the classes:
    archive_jini=frmall_jinit.jar,...,my_jar_file.jar
    Then after, you have 2 possibilities:
    - the bean does not have any "screen" representation so you can just handle its functions with the Forms internal FBean package functions (no need to put implementation class on the bean area item property)
    - it has a screen representation, so you put its implementation class like you did, and you set its properties with the Set_Custom_Property() built-in and get its properties with the Get_Custom_Property() built-in.

    exception
    org.apache.jasper.JasperException: Cannot create bean of class Counter

    Java is already telling you what is wrong: it cannot create an instance of your Counter class. The reason being: it can't find it.
    What do you mean by "myPackage"? Before you can use any class in your JSP's or servlets, they MUST be stored in a package. If you don't know what that is, I highly suggest you lookup "java package" and "java classpath" using google.
    Let's say your Counter class is in a package mypackage (so it starts with the line package mypackage;). Then you have to store the .class file as:
    WEB-INF/classes/mypackage/Counter.class
    If done correctly, the error message should disappear.

  • How to include PJC and Java Beans in forms

    I have tried a lot to include java codes in my forms ..So I decide to start with ProgressBarPJC(cause it is tested and provided with demo) but I could not set implementation class of java bean object to
    oracle.forms.demos.ProgressBarPJC it does not accept it but it accept ProgressBar instead of ProgressBarPJC. I don't know why? I have made changes in Forms90_builder_classpath to access f90all.jar and progressbar.jar. I have Progressbar.class and progressbarpjc.classs both but i don't know how to set implementation class to ProgressBarPJC.
    don't you think there is lots of configuration and path setting to use any JPC or Jar in forms? I am totally confused with this integration.
    Please solve this matter
    Thanking you,

    and even more information samples and step by step instructions are on the Java spotligh on the Forms Upgrade Center : http://otn.oracle.com/formsupgrade

  • Need advice about web services and Java beans

    Hi
    I am very new to web services and to Java beans as well.
    I am trying to understand if and how a web service can use functionality I have in a Java bean. I couldn't find any documentation I can use.
    For example:
    InitialContext ic = new InitialContext();
    Adder adder = (Adder) ic.lookup("ejb/AdderJNDI");In a EJB client project (I'm working with Eclipse) if I add the EJB project to the build path, the Adder interface is recognized.
    Theoritacally I thought I can do the same in a web service server project, but the Adder interface is not recognized.
    Is there something I can read to understand how I need to use the EJB or implement the web service?
    Many thanks
    Sigal

    Okay....I think I made some errors with the original scenario:
    It basically comes down to this....I think. OCS Calendar has a set of Java classes and methods that provide an abstraction for their web services interface. I know how to create something to use these classes using an IDE like JDeveloper, but I'm not sure how that would work with HTML DB.
    I've noticed that the SQL Workshop has a place for Java sources and classes, and I've heard mentions of PL/SQL wrapping. Is there a way to import classes into an HTML DB workspace, wrap 'em up, and access them via PL/SQL?
    Thanks again,

  • First use of jsp and java bean and "Unable to compile class for JSP" error

    Hi,
    I am trying to create my first jsp + java bean and I get a basic error (but I have no clue what it depends on exactly). Tomcat seems to cannot find my class file in the path. Maybe it is because I did not create a web.xml file. Did I forgot to put a line in my jsp file to import my bean?
    Thank you very much for your help.

  • Popup menus in Forms 10g and Java Bean

    Hi all.
    What class in Java corresponds with popup menus(not in menu module) ?
    I know that oracle.ewt.lwAWT.lwMenu.LWPopupMenu is corresponds with MenuBar's submenu. I can find Buttons, Text Fields, Menu and other components in my Form-Applet, but I don't know how to find popup menus in forms through Java Bean...

    Hello François,
    I have created a java bean that dynamically creates a popup by left-clicking on the bean.
              Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_ITEM', 'Item' ) ;
              Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_SEPARATOR', '' ) ;
              Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_ITEM', 'Item one' ) ;     
              Set_Custom_Property( 'BLOCK.BEAN', 1, 'ADD_ITEM', 'Item two' ) ;
    My problem is the layout. I want to simulate a button. I can't put the bean transparent over a button and I can't simulate a button with the bean.
    How can I add the popup functionality to a button and not only to the bean? Or any other workaround?
    Regards Pedro.

    My question is :what is the best solution for such kind of programes

  • How to increase Memory and Java Heap Size for Content Server

    Hi,
    My content server is processing requests very slowly. Over performance is not good. I have 2 GB of RAM any idea what files I can modify to increase the Java Heap Size for the Content Server. If I increase the RAM to 4 or 6 GB where do I need to make changes for the Java Heap Size and what are the recommended values. I just have Content Server Running on the linux box. Or how do I assign more memory to the user that owns the content server install.
    Thanks

  • JAX-RPC ArrayLists and Jave Beans

    Can any one tell me if JAX-RPC supports an ArrayList of JavaBeans

    In my experience, Apache Axis is capable of serializing and deserializing any java.util.Collection instance, provided it can serialize and deserialize the objects held by the collection. This means that a List populated with beans should cause no problems.
    A word of caution though: XML serialization of objects is nowhere near as fast as the 'usual' Java serialization. This means that -if you're sending or receiving large amounts of beans per call- you might consider sending and receiving the List as attachment (ie: binary). I realize this defeats interoperability for the related web service methods, but having your users wait dozens of seconds on responses is rarely a viable alternative.
