How to set the classpath and path from the jsp to call java class function

Hi Exprets,
I have a requirement to call a java class function which returns a hashmap object from the jsp. The java class in present in one jar file and that jar file is location somewhere in unix path. So the requirement is to set the classpath for that jar file and then create the object of the java class and then call the function.
If any one know how to achieve it, please reply as soon as possible.

It is never advisable to store large data sets in the session. But it will depend on a lot of factors:
1. How costly is the query retrieving the data from the database?
If it's a complex query with lots of joins and stuff, then it will be better to store it in the session as processing the query each time will take a lot of time and will decrease performance. On the other hand if the query is simple then it's advisable not to store it in the session, and fetch it each time.
2. Are there chances for the data to become stale within a session?
In this case storing the data is session will mean holding the stale data till the user session lasts which is not right.
3. How many data sets does the session already holds?
If there are large no. of data sets already present in the session, then it's strictly not advisable to store the data in the session.
4. Does the server employ some kind of caching mechanism?
Using session cache can definitely improve performance.
You will have to figure out, what is the best way analyzing all the factors and which would be best in the situation. As per my knowledge, session is the only place where session specific data can be stored.
Also, another thing, if the data set retrieved is some kind of data to be displayed in reports, then it would be better to use a pagination query, which will retrieve only the specific no. of rows at a time. A navigation provided in the UI will retrieve the next/previous data set to display.

now we are trying to rebuild new servers to restore DB's. the new servers is prompting the product key to be entered. unfortunately we don't have product keys of exchange 2010. since we are gold partner we have partner network portal. when i tried to get
the product key from portal am able to see only 2013 keys. we called up Microsoft and explained but no use. they said we have to use exchange 2013. but we cant simply go ahead and migrate.
but the only option is we have exchange 2010 installed servers they all act as CAS/HUB server with the same licence. please let me know how do i retrieve exchange 2010 product keys from an existing servers. Please advise me its very critical.

It would have helped if you had posted your code as CODE but as it is, I could hardly read it. My guess about what you are asking is, if you want a template to return a value, just write that value to the result stream inside the template.
If that wasn't what you were asking, then please post your code in a readable format.

Jsp:usebean How to get value of an object from a bean

I am new to JSP and am struggling from past few days to solve a problem. Consider the below scenario
Class Book{
private String author;
public void setAuthor(String author)
public String getAuthor(){
return author; }
Class Rack{
private Book []books;
public []Book getbooks()
return books;
public void setbooks([]Book val){....}
Suppose Books gets populated only using Rack and I have Rack populate in my session, using jsp:usebean or any other tag how can I get value of author? Does using tag handle null value check of books, if books are not set by any chance?
Regards,
Dhyan

I got a way out to access the attribute, i feel it is
<jsp:usebean id="myRack" class="settings.Rack"/>
<c:foreach var="book" item="myRack.books">
</c:foreach>
I am not able to check if this is correct or not because myRack.books is not having any value set by me in the request scope. How do i get instance of Rack class set by another page in the current request? I can get the value if i use scriptlet but i dont want to use scriptlet.
I am continiously trying, if I get an answer, I shall post, else pls somebody guide.

How to get value in backing bean from application module

Hi all.. I'm new in jdeveloper and adf..
I need to use value from backing bean and use that value in application module.
But I don't know how to get it.
Do you a have any solution?

suppose you have myMethod(String argumentName1,String argumentName2) in your Application Module
then to access a method binding from a managed bean, use the following code,
BindingContext bctx = BindingContext.getCurrent();
BindingContainer bindings = bctx.getCurrentBindingsEntry();
OperationBinding operationBinding =
       bindings.getOperationBinding("name_of_method_binding");
//Here you can pass the parameters value to the AM method
operationBinding.getParamsMap().put("argumentName1",value1);
operationBinding.getParamsMap().put("argumentName2",value2);
//invoke method
operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {

How to get value object (entity abject) from ViewObject?

How to get data from ViewObject in the form of value object? I know BC4J creates entity object for database table/view (looks like value object) but I did not find api to get entity object from ViewObject.
Thanks.

BC4J provides an implementation of the value object design pattern for you, so you don't have to waste time writing your own.
I wrote a whitepaper illustrating how to take advantage of this at:
Implement Collections of Value Objects for MVC Apps with BC4J
This allows clients (like a servlet, a JSP, a Swing client, etc.) to get value objects from the collection of value objects that BC4J supports.
However, if you are writing code inside your view object implementation class and want to access the entity object, just call the accessor that we generate into your view row implementation class for you. For example, for a VO named EmployeeView that uses an entity object named Employee, there will be a private accessor method getEmployee() that will give you the entity.

How to get value in dashboard prompt from database

Hi All,
I am using dashboard prompt (Year Prompt) to filter reports on year basis.
fact table stores the hit date on a particular site linked with date dimension table .
I have Datas in fact table say from year 2005 to 2009 .In dashboard Prompt it is showing me all the years 1990 to 2021(that are in date dimension).
I hard coded the value of years in prompt now it only showing me years 2005 to 2009.
My question is that is their any way that prompt automatically take values from database, those years which are stored in fact table ?
Thanks in advance.

Hi...
Try writing query for dashboard prompt to get desired values..
*select distinct year(FactTable.HitDate) from SubjectAreaName*
To work this.. you should have HitDate column in presentation layer. (You can drag this column from fact in BMM and drop in any dimensions of presentation Layer, and name it as HitDate (Fact).. some thing like this...

How to get value of a structure from a standrd program to Z program

There is a standard program which generates a file when it is run a file is created
The name of the file is stored in a structure. I am submitting this standard program in my Z program I have to get the file name from the structure

Hi,
Does this help?
you can retrieve the content of a structure from another shared memory by assigning it with a field symbol:
e.g.
FIELD-SYMBOLS: <staffel> TYPE table.
* get itab data from SAPMV13A
ASSIGN ('(SAPMV13A)STAFFEL[]') TO <staffel>.

How to get values/data stored in the database into a list-item.

how to get values/data stored in the database into a list-item.
i tried to make a list item without any values assigned to it...but i got the below error.
FRM-30191: No list items defined for required poplist.
or
FRM-32082: Invalid value for given item type.
List EMPNO
Item: EMPNO
Block: EMP
Form: MODULE5
FRM-30085: Unable to adjust form for output.
then according to some docs, i tried the the following for the trigger
when-new-form-instance
declare
     rg_name varchar2(40) := 'emp_rec';
     status number;
     groupid recordgroup;
     it_id item;
begin
     it_id := Find_Item('empno');
     groupid := create_group_from_query(rg_name, 'select empno from emp');
     status := populate_group(groupid);
     populate_list(it_id, groupid);
end;
but yet didnt work... :(
so how the heck do i get values fetched from the database table into the list item?

for list items you need to values in the record group, one is the shown value and one is the returned value.
Check out the online help for the populate_list built-in.
You'll need something like select ename,ename from emp as the record group query.

How to get password as string back from encrypted password byte array.

I am storing encrypted password and enc key in the database.(Code included encryptPassword method for encryption and validatePassword method for validating of password). Problem is that for some reason i need to show user's password to the user as a string as he/she entered. But i am not able to convert the encrypted password from D/B to original String.
Tell me if any body know how to get the string password back from the encrypted password byte array after seeing my existing encryption code.
//********* Code

Hi All,
I am storing encrypted password and enc key in the
database.(Code included encryptPassword method for
encryption and validatePassword method for validating
of password). Problem is that for some reason i need
to show user's password to the user as a string as
he/she entered. But i am not able to convert the
encrypted password from D/B to original String.No, you are not encrypting the password in your code, you are merely signing it.
Tell me if any body know how to get the string
password back from the encrypted password byte array
after seeing my existing encryption code.It is impossible to retrieve the original text out of a signature.
You should read up on some encryption basics in order to understand the difference between signing and encrypting. Then you can find examples of how to encrypt something here: http://java.sun.com/j2se/1.4/docs/guide/security/jce/JCERefGuide.html.
Actually there is one class specifically for keeping keys secure, KeyStore http://java.sun.com/j2se/1.4/docs/api/java/security/KeyStore.html

How to get the Portal Page name from PLSQL?

Can anyone tell me how to get the portal page name from my dynamic page using plsql?
Apparently you can get the page id and work it out from there, but my calls to get the page id are not returning any values anyway.
My code for attempting to get the page id is below.
<oracle>
declare
v_pageid varchar2(30);
begin
v_pageid := wwpro_api_parameters.get_value('_pageid', '/pls/portal30');
htp.print('Page is '|| v_pageid);
end;
</oracle>
Ideally I'd actually just like to get the page name. Is there a straightforward way to do this?
Thanks in advance!
Sarah

Few clarifications -
1. wwpro_api_parameters cannot be used to get default portal
page parameters such as '_pageid', '_dad', '_schema' etc.,
2. Page information can be obtained through any components which
are available in that particular page. For example, in case of
dynamic page, we need to publish it as a portlet and add it to the
page. This process creates necessary packages in the DB, but we
will not have access to the portlet methods.
So, I would prefer creating a simple DB provider & portlet and access
page title from its show method as follows -
//Declare local variable l_page_id, l_page_title as varchar2
select page_id into l_page_id from wwpob_portlet_instance$ where
portlet_id = p_portlet_record.portlet_id and
provider_id = p_portlet_record.provider_id;
select name into l_page_title from wwpob_page$ where id=l_page_id;
More information on DB provider can be found at
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/articles/understanding.database.providers.html
Secondly, usage of wwpro_api_parameters.get_value method is
incorrect. This method expects two arguments -
<ul>
<li><b>p_name : </b> The name of the parameter to be returned.</li>
<li><b>p_reference_path : </b> An unique identifier for a portlet instance on the current page.</li>
</ul>
p_reference_path would be something like 99_SNOOP_PORTLET_76535103 and not some type of path as its name suggests.
The following code fragment fetches all parameters available
for a portlet.
Note : Copy this code into 'show' method of your portlet.
//Declare l_names, l_values as owa.vc_arr
* Retreive all of the names of parameters for this portlet
l_names := wwpro_api_parameters.get_names(
p_reference_path=>p_portlet_record.reference_path);
* Retreive all of the values of parameters for this portlet
l_values := wwpro_api_parameters.get_values(p_names=>l_names,
p_reference_path=>p_portlet_record.reference_path);
//Loop through these arrays to get parameter information
htp.p('<center><table BORDER COLS=2 WIDTH="90%" >');
htp.p('<tr ALIGN=LEFT VALIGN=TOP>');
htp.tableData(wwui_api_portlet.portlet_heading('Name',1));
htp.tableData(wwui_api_portlet.portlet_heading('Value',1));
htp.tableRowClose;
if l_names.count = 0 then
htp.p('<tr ALIGN=LEFT VALIGN=TOP>');
htp.p('<td COLSPAN="2">'
||wwui_api_portlet.portlet_text(
'No portlet parameters were passed on the URL.',1)
||'</td>');
htp.tableRowClose;
else
for i in 1..l_names.count loop
htp.p('<tr ALIGN=LEFT VALIGN=TOP>');
htp.tableData(l_names(i));
htp.tableData(l_values(i));
htp.tableRowClose;
end loop;
end if;
htp.p('</table></center>');
Hope it helps...
