Probably "session" was a wrong word to use ..I think I got the discussion off track here ...

Let me try with an Example ...

This web page has a general URL (GET) where the last part of the URL is an everchanging ID
http://www.ncbi.nlm.nih.gov/entrez/viewer.fcgi?db=nucleotide&val=AI847983

For our purposes I am assuming that I would want to make the above web application a portlet

Say a user (external user not from www.ncbi.nih.gov) wants to get the information about a gene(from his web application) he would dynamically change the ID that would lead him to this web site.

If my purpose is to make a portlet out of this(www.ncbi.nlm.nih.gov) where the external users can link by the changing the ID ..how would I do this ?

I have not used struts (we use our own framework) , but if this were a normal
MVC jsp with a controller , I would do something like this

In the JSP

<tr><td><a href="<portlet:actionURL>
<portlet aram name="mainGet" value="yes" />
</portlet:actionURL>">
<b> D</b></a></td></tr>

In the Controller :
In the Process action direct , interact with the model and the requisite logic and move the action to the VIEW which would display the JSP

public void processAction(ActionRequest request, ActionResponse response) throws PortletException, java.io.IOException {
....
....

if(command.equals("MASTER"))
request.getPortletSession().setAttribute("page",PAGE_MASTER);

}
response.setPortletMode(PortletMode.VIEW);


Thinking in these lines should help you for your struts app.

Hope this helps

I am not sure if this is a drawback for portlets (and portals) in general , but I am wondering if there is a workaround for this.

In the field of Bioinformatics (where I currently work) there is a heavy use of GET method where ID's are passed around in the URL .Is there a way in Portals where we can mimic this functionality ...so as to jump to a specific
"session" directly bypassing the "usual stuff".

Thanks

I would check with a simple portlet to begin with

If it is a Websphere portal I would go with the example given in IBM Redbooks http://www.redbooks.ibm.com/redbooks/SG246681/wwhelp/wwhimpl/java/html/wwhelp.htm
Look at chapter 13 and 14 carefully , they go through the process of creating a "struts based portal".This might help for a simple portal.

But if it is not a Websphere portal make sure that the example is not using the Webshphere API .(Will not work on non-websphere)

Test 257 Enterprise Application Development with IBM Rational Application Developer for WebSphere Software V6.0

Seems to be the most comprehensive and updated , is this the most sought after
in the category ? ..I am confused in here (literally feel this)
Hello ,
I have cleared SCJP,SCWCD,SCBCD and was looking at certifications offered at IBM.But I am not sure which one of these suits me (There are a plethora of those ) .I am really confused with the details in there.I am not even sure if some of the exams there are relevant ...

Aprreciate yor time.
I have just cleared the 310-090 (EJB) exam and am contemplating whether to take the SCEA or the webservices exam .

I have a couple of questions regarding the same ...

1.Do I get Individual certificates for each part of the SCEA exam .
2.Does the 310-090 (EJB) help while preparing for the SCEA ( I see there is a EJB component to this)


Thanks for your time.

Hello All ,


When we write EJB-QL queries and work on entity beans , are they (EJB-QL) compiled to normal SQL (somewhere ...) if so ,who does it ?.And , is this (QL-SQL) the only way that it is done ?

Thanks for your time.

Chaitanya
Congratulations !!!

If you dont mind could you answer a few questions of mine ...

1.Did you have EJB experience before ?
2.How many days did it take to prepare for the exam ?
3.What was your score in the HFEB mock exam ?

Appreciate your time.

Thanks
