This happens when hibernate gets the currentSussion

Hi Claude, i opened the ibm-ejb-jar-bnd.xml and noticed that remote beans are referenced in two ways, using <interface /> tag and others <ejb-ref /> tag... In our architect design the <interface /> references the session facade EJBs and <ejb-ref> to Business objects EJBs (BOBeans). Only the BOBeans referenced with <ejb-ref> are visible under ejb-references in my app on admin console. Mine is mapped using <interface />
Hi, our ibm-ejb-jar-bnd.xml containes quite a number of session beans with remote/local references. I noticed that not all of them are loaded to the container. I see this when i open ejb references on websphere admin console within the application. Aslo, if i deploy the application using the workspace it takes forever, but installing it through admin console gets through successfully, except the above. Is this caused by the cache size or bean allowed in the session?

Hi .. say i have three tables Override (Parent), OverrideItems (Link Table), Items (Child). Item has only two columns "ItemID" (primary key) and "ItemValue". When i add new Override and its items i would like to reuse existing ItemValue if user has entered existing ItemValue for the new Override. Otherwise inserts new ItemValue if none existing. I noticed a "many-to-many" unidirectional mapping will allow duplications meaning i could have same item inserted with different ItemID, how do i avoid this? Is making ItemValue UNIQUE Index/Constraint enough to enforce this

Alright thanks

If your OverrideID is an identity column (autonumber, sequence etc.) than it should work else it will not cause this is what is using the identity generator class.



Thanks Bogdan, was also more worried about the children's ID (ItemID) ....
Hi, i'm having a parent to children mapping with a link table



if i use session.saveOrUpdate(batchOverrideDo) without having set the overrideId and all the children IDs (all null), will hibernate take care of that or should i at least set the children IDs to a value? TaskOverride and OverrideItem are my two link tables for my children
Th e HttpSession seems to be working for both

Here, you have given the submit-button the same name you've given for your select box. You don't need a name for a submit button. Even if you provide, it'd be better to use a unique name.

HTH,

I removed the name attribute and gave it the value attribute... Another question on HTML, i need to do two things

1. Pass a list of objects from doGet() to doPost() .. should i just put it on HttpSession?
2. Keep track of the EJBRemote reference so that i don't have to look it up on the JNDI context everytime i need it. I tried putting it on the HttpSession but it becomes null

Thanks

i had to set the selected value to get it working


But still the getParameterNames didn't get me the values. I had to change code to the following to get it to work, not sure why

Hi, i have the following form

and this is how i plan to get the values

only "parameters exhausted ...." is displayed which means the param list is null/empty... Is JSTL setting 'username' parameter?

1. If you are using EJB3 then you will need Remote interface file with annotation @Remote.

2. The bean class will need to implement the remote interface. It will have @Stateless annotation.

3. Under same JVM, the JNDI lookup code should be done using the full qualified remote interface class name.

4. Suggest you clear the websphere temp dir and see if anything changes.



Hi Deepak, my mistake was still using the server code not the stub created to declare the remote object. Both these are in the same workspace.. Its now working thanks

Hi, i have created a servlet class with doGet()/doPost() methods and a jsp file. I need to populate this JSP with dropdown list data from the database. All i have is a dropdown box on the jsp
and here's my servlet

To run this app i went to jsp right clicked and Run on server. The page loads with no errors by i think the doGet() was never invoked. No logs, errors or warnings, just an empty drop down
here's my web.xml

am i missing a step here? do i need an index page

They both on the same JMV... Am running Websphere locally if you like. By the way, do i need EJBRemote in this case?
