Bean Value display in JSP Page

Hi,
I am trying to display a value stored in my bean on the jsp page. The value is to be displayed on the initial jsp page.
   public void doInitialization()
          request = (IPortalComponentRequest) this.getRequest();
          response = (IPortalComponentResponse) this.getResponse();
          myContext = request.getComponentContext();
          myProfile = myContext.getProfile();
          Statement += "doInitialization";
          BeanContainer = new MockUpBean();
          BeanContainer.setValues( Statement);
          myProfile.putValue( "myBean", BeanContainer);
          // reset String
          BeanContainer = ( MockUpBean) myProfile.getValue( "myBean");
    }// public void doInitialization()
On the JSP Page side:
<jsp:useBean id="myBean" scope="application" class="MockUpBeanPackage.MockUpBean" />
<%= myBean.getValues()%>
The jsp page does no pick up the value I try to store in the doInitialise method.
Any thoughts on what I may have done wrong in my code.
I try response.write("Test"), this too does not show up in my JSP page.
Any advice would be appreciated.
Thank you
NAC

Marty,
The portalapp.xml file is as follows:
<?xml version="1.0" encoding="utf-8"?>
<application>
<application-config>
    <property name="PrivateSharingReference" value="com.sap.portal.htmlb"/>
</application-config>
<components>
    <component name="MockUpPage">
      <component-config>
        <property name="ClassName" value="MockUpPackage.MockUpPage"/>
        <property name="SecurityZone" value="MockUpPackage/low_safety"/>
        <property name="ComponentType" value="jspnative"/>
        <property name="JSP" value="pagelet/InitialPage.jsp"/>
      </component-config>
      <component-profile>
        <property name="tagLib" value="/SERVICE/htmlb/taglib/htmlb.tld"/>
      </component-profile>
    </component>
</components>
<services/>
</application>
Again any help would be apreciated. I have used this piece of code to write values to beans in various projects, never had any issues. This is the first time I am having an issue with this piece of code.

ADF BC how to access session backing bean value in servlet

Hi everyone,
How do I access session backing bean value in a servlet?

Frank, thanks for your reply.
I'm not sure how I can incorporate this example into my situation. Let me explain more detail about my problem.
"servlet" in my post here actually means a custom servlet I wrote for rendering an image that is stored in db as ordimage. In this servlet, I get hold of my appmodule by using Configuation.createRootApplicationModule(). By doing so (If I'm not wrong) a new database session/connection is created. What I'm going to achieve is set application context for this new session/connection in db with the data stored in a session backing bean in the view layer.
I can pass the required data to the servlet thru url parameter, but I don't want to do it this way for the reason that the data may contains sensitive information.
I hope I have explained myself well.

How to assign bean value to a local variable in JSP using struts.

Hi everybody!
I've a problem that puzzled me on how to assign a bean value to a local variable like String in JSP using struts.
we can have someting like this to display the value
<bean:write name="detailService" property="status" />or
<bean:define id="theStatus" name="detailService" property="status"/>
This is country: <%=theStatus%>but an error occured when I tried like this:
String currentStatus = "<bean:define id="theStatus" name="detailService" property="status"/>";
or
String currentStatus = "<bean:write name="detailService" property="status" />";Is there a way to do this?.....
Any help pretty much appreciated

Java != JSP.
The <bean:define> and <bean:write> tags are custom tags meant to appear in the HTML section of a JSP file, as opposed to the scriptlet section. They actually get turned into java code as part of the translation process.
The <bean:write> tag naturally just writes out what you tell it to.
The <bean:define> tag defines a local variable, and gives it a value.
this should do it.
<bean:define id="theStatus" name="detailService" property="status" type="java.lang.String"/>
<%
String currentStatus = theStatus;
%>With the advent of JSTL, you shouldn't really need to use scriptlet code anymore. Personally I am for 0% scriptlet code in any jsp I write.

How to find out the type of the value stored in a string variable?

1) Intger
2) Long
3) boolean
4) Char
Is there any method to find out the type of the value, anything like str.getType()?. Please kindly help me. Thanks in advance.

Hi All, i'm sorry for the double posting, by mistake it occured.
Thanks for your replies, i have a string variable str, in which the value is stored and i have another string variable type, in which the type of the value is stored.
For example,
String str = "15";
String type = "Integer";
Is there any way to verify whether the value stroed in str is of type stored in the variable 'type'. I want to write a method of type boolean, it will throw true of the value stored in str is of type 'type'. Thanks

I do not know how to put the values stored in the session object into the html text box

3. If the id is correct then pulled the record of the corresponding employee and stored it in the session object.do you really need to store this in session object?
5. Now i need to set the session values in the text field of the html form which form? in a new html/jsp page? i suggest go for a JSP
In your JSP page use JSP expression tags to put the session attributes.
it's something like : <input type='text' name='employeeid' value='<%= session.getAttribute("employeeid") %>' >and you need to generateanother servlet for saving the details/modifications to the database.
I think i m clear enough.
if you need more clarifications. just try it and then post your problem.

SAP-R/3- In which table, numeric values stored in equipment characteristis

SAP-R/3- In which table, numeric values stored in equipment characteristis are captured.
In AUSP table Char values in equipment characteristics are captured against object number.But this table does not cappture numeric characteristics.
Are these numeric values captured in any function module?

Hi
check the BAPI for characteristics
BAPI_OBJCL_GETDETAIL
BAPI_OBJCL_CHANGE
or use the fun module:
CLAF_CLASSIFICATION_OF_OBJECTS.
You can use the tables
CAWN,INOB and AUSP to get the characteristics

Analysing waveform for digital values stored in a file

i have certain digitals values obtained in a file in .txt format.
i have to obtain a waveform by giving the input as these digital values in that file.
I have programmed for array input manually.
But the waveform analysis should be made such that it do analyze automatically by taking the values stored in the file.
The values are stored as like follows-
0.00159
0.01432
0.01654
0.15432
etc
Give me a module to do this task.

Use the Read from Spreadsheet file and then just connect it to a waveform chart. This will do what you need. Post back.

How to call the form bean value on jsp withthe help of jstl tag

hi
all friends
i am working in struts & i use jstl tag in jsp. i have one problem rise is how to call the form bean value in jsp page by using jstl tag.
i now how to retrive the value through jsp:logic
eg. <logic:empty name="userListForm" property="users">
NO USER FOUND
</logic:empty>
see * userListForm mean formbaen name.
* users means collection object.
so how can i write above e.g in jstl

You use the jstl core:if or core:choose combined with the EL:
<c:if test="${empty users.userListForm}">
NO USERS FOUND
</c:if>I suggest you lookup the jsp expression language (EL) using google, it's very powerful.

How do I update a bean value from an AJAX call?

Hi all,
How do I update a bean value from an AJAX call? I suppose I could write a servlet to do it. However, this seems like a common problem, so I was wondering if there was some built in solution.
Thanks,

Basically, I would user the following. The first choice for IE, the second for Firefox.
new ActiveXObject("Microsoft.XMLHTTP");
new XMLHttpRequest();
GraeDon't do this to yourself. If it were that easy there wouldn't be AJAX frameworks for JSF. Find one you like and use it. I've used a4j (part of RichFaces) successfully.

Access values stored in 2D Array in HashMap

Hi everyone i would like to know how to access values stored in a 2D array inside a HashMap
Here is a drawing representation of the map.
So to get the KEYS I just have to execute this code:
this.allPeople = personInterests.keySet();But how can I get acces to the actual values inside the 2D Array?
My goal is to create a treeSet and store all the elements of the first array in it, then look at the second array if any new elements are detected add them to the treeset, then third array and so on.
I tried this code:
Object[] bands = personInterests.values().toArray();
     for( int i=0; i<bands.length; i++)
          this.allBands.add(bands.toString());
}But this.allBands.add(bands[i].toString())seems to be the problem, Dealing with a 2D array, this code only return a string representation of the Arrays and not a string representation of their elements.
Using my logic I tried to execute:
   this.allBands.add(bands[0][i].toString());But i get a ARRAY REQUIRED BUT JAVA.LANG.OBJECT FOUND
I really don't know the way to go.
Thanks to anyone that will help.
Regards, Damien.
Edited by: Fir3blast on Mar 3, 2010 5:27 PM

You'll just need to cast the object to the correct type. This is nothing to do with HashMap at all. If you don't know what that means then your google keywords are "java cast tutorial".
