How to Persis session between two ear files

Can anybody tell me how to persists session between two ear files?
Please Help its urgent!!
Rahul

Rahul -- there's nothing as a J2EE spec requirement or even a proprietary feature of OC4J/OracleAS which will enable this.
If you have two different EAR files, then they are two different applications, and each will have their own session which can't be shared amongst each other.
If you have data which needs to be shared across different applications then you could either put it on a shared file system or write it to a database which you can then read from in the other application.
One way to do this is to implement the HttpSessionAttributeListener interface which will be called when object are added/removed/updated from a session, and then make a determination on whether the new object needs to be stored in a common place to facilitate sharing between applications.
This is more likely to be a hackaround and ideally you'd examine why you want to share session state across applications and rearchitect so you don't need to do it -- but if you want to try a solution without a major revisiting of the whole application, then perhaps it's an option.

Hi,
No it would not be possible to differentiate the data just by using the dump files. You need to import these dump files in the database and then you can compare it for any difference.

How can pass information between 2 par file in iView???

Hello,using PDK i've have created an iview calling 2 .par file, the first par file contains a menu that the user selects a products and then when press load button generates a table with information. The table with information is generated in second .par file, that collects the information passed by the menu (through beans) and with a BAPI generates the table. I made it because the menu must be separated in one frame, and the table in other...(and the first frame must displace, how a html frame)
The question, how can pass information between two par files or if are another method to made 2 frames????
I'm using jsp,HTMLB .
Thanks.

How to pass data between two internal sessions using ABAP memory?

Hi,
How to pass data between two internal sessions using ABAP memory?
It would be fine if you could explain with an example.
And also let me clear about the data passing between two main sessions and two external sessions with specific examples.
Thanks.

Hi ,
check the example.
Reading Data Objects from Memory
To read data objects from ABAP memory into an ABAP program, use the following statement:
Syntax
IMPORT <f1> [TO <g 1>] <f 2> [TO <g 2>] ... FROM MEMORY ID <key>.
This statement reads the data objects specified in the list from a cluster in memory. If you do not use the TO <g i > option, the data object <f i > in memory is assigned to the data object in the program with the same name. If you do use the option, the data object <f i > is read from memory into the field <g i >. The name <key> identifies the cluster in memory. It may be up to 32 characters long.
You do not have to read all of the objects stored under a particular name <key>. You can restrict the number of objects by specifying their names. If the memory does not contain any objects under the name <key>, SY-SUBRC is set to 4. If, on the other hand, there is a data cluster in memory with the name <key>, SY-SUBRC is always 0, regardless of whether it contained the data object <f i >. If the cluster does not contain the data object <f i >, the target field remains unchanged.
In this statement, the system does not check whether the structure of the object in memory is compatible with the structure into which you are reading it. The data is transported bit by bit. If the structures are incompatible, the data in the target field may be incorrect.
PROGRAM SAPMZTS1.
DATA TEXT1(10) VALUE 'Exporting'.
DATA ITAB LIKE SBOOK OCCURS 10 WITH HEADER LINE.
DO 5 TIMES.
ITAB-BOOKID = 100 + SY-INDEX.
APPEND ITAB.
ENDDO.
EXPORT TEXT1
TEXT2 FROM 'Literal'
TO MEMORY ID 'text'.
EXPORT ITAB
TO MEMORY ID 'table'.
SUBMIT SAPMZTS2 AND RETURN.
SUBMIT SAPMZTS3.
The first part of this program is the same as the example in the section Saving Data Objects in Memory. In the example, the programs SAPMZTS1 and SAPMZTS2 are called using SUBMIT. You can create and maintain the programs called using the SUBMIT statement by double-clicking their names in the statement. For further information about the SUBMIT statement, refer to Calling Executable Programs (Reports)
Example for SAPMZTS2:
PROGRAM SAPMZTS2.
DATA: TEXT1(10),
TEXT3 LIKE TEXT1 VALUE 'Initial'.
IMPORT TEXT3 FROM MEMORY ID 'text'.
WRITE: / SY-SUBRC, TEXT3.
IMPORT TEXT2 TO TEXT1 FROM MEMORY ID 'text'.
WRITE: / SY-SUBRC, TEXT1.
Example for SAPMZTS3:
PROGRAM SAPMZTS3.
DATA JTAB LIKE SBOOK OCCURS 10 WITH HEADER LINE.
IMPORT ITAB TO JTAB FROM MEMORY ID 'table'.
LOOP AT JTAB.
WRITE / JTAB-BOOKID.
ENDLOOP.
The output is displayed on two successive screens. It looks like this:
and
The program SAPMZTS2 attempts to read a data object TEXT3 from the data cluster "text", which does not exist. TEXT3 therefore remains unchanged. The existing data object TEXT2 is placed in TEXT1. In both cases, SY-SUBRC is 0, since the cluster "text" contains data.
The program SAPMZTS3 reads the internal table ITAB from the cluster "table" into the internal table JTAB. Both tables have the same structure, namely that of the ABAP Dictionary table SBOOK.

How to get relationship between two views in the reports

How to get relationship between two views in the reports, I am doing a deletion program , it is fully relates to views , how to get relationship between them in the reports

Hi,
Please explain your question in detail...what do you want to read ?
If you want to know about the navigation links between the views then you can use APIs like
wdComponentAPI.getComponentInfo().findInWindows("windowName").getViewUsageByID("Name").getNavigationLinks();
Iterate through the navigationLinkInfo from above collection and can read the other properties .
I haven't tried the above , but it should work !!!

How can we navigate between two windows of same component in webdynpro ABAP

Hi
how can we navigate between two windows( not views ) of same component in webdynpro ABAP. its an urgent requirement
Thanks in advance.
Regards
Laeeq

Hi Laeeq,
You cannot navigate between windows of one component. You can only call a dialog box showing the contents of a second window, or you can embed the contents of a window of a different component.
Just add all the views you need to the one and only main window of the component.
