Java/Struts training

Greetings!
I'm a developer with extensive background in Perl, C, Oracle and OBIEE. However I've never had to deal with Java. My boss wants me to work on some Java/Struts project and wants to send me to training.
I wonder if anyone could advice me:
First - what exactly classes I should take. I would assume I would have to take some Java for beginners class, and then a Spruts class?
And second - if anyone can recommend a training facility in DC/VA/MD area.
All suggestions appreciated. Thank you!

Struts specific training may not be available, but Struts as a component of a training module would be available. Refer

How to use VPD in Java/Struts JSP portlet with SSO

DB = 10.1.0 (Standard Edition)
Portal = 9.0.4.1
10gAS = 9.4.0.1 (EE)
I am in the beginning stages of developing some portlets that will be Java/Struts JSP based. We use SSO and have implemented some VPD security in our DB by creating some views that use SYS_CONTEXT('USERENV','CURRENT_USERID').
These Java portlets connect to the DB using a defined JDBC connection for the OC4J container they are deployed in. The problem I'm having is that the call to SYS_CONTEXT is returning the user of the JDBC connection and not the SSO user. So far I have been unable to find any documentation that will point me in the right direction to get this configured properly.
Deployment and configuration are as follows. Deploy war file to custom container on app server. In the configuration of the OC4J contain the app used the containers default JDBC connection using the oracle.jdbc.pool.OracleDataSource class. Max and Min open connections are blank.
In the portal configuration under Navigator - Providers tab we defined a new Registered Provider. In the Connections tab for the provider we Specify the URL Http://hpsrv02.simsol.com:7777/discovery-portlets/providers. Under "Specify how the user's identity will be set by the Portal..." the "The user has the same identity in the Web providers application as in the Single Sign-On identity" is selected. Under "User/Session Information" User is selected and Login Frequency is set to "Once per user session". Then we created a new portal page and created a new portlet with the new provider.
Just an FYI I do have Discoverer working with VPD and any report portlet, dynamic page portlet and any other type of portlet I created all work correctly with VPD it is just the java/struts one that is not working.
So does any one have any insight into what configuration steps I have missed?
Any help is much appreciated,
Ed Klinger

Ed,
Your java code must get the SSO username (it's just a HTTP header variable) :
ie: code sample...
Enumeration e = request.getHeaderNames();
while (e.hasMoreElements()) {
String name = (String)e.nextElement();
String value = request.getHeader(name);
out.println("<br> "+name + " = " + value);
if (name.toUpperCase().trim().equals("OSSO-USER-DN")){
dn_user=value;
out.println("<br>******** USER DN = "+dn_user);
Then, the SSO username can be used in the VPD policy.
Note that there is a difference between the sso username and the database username . SSO username is not known by database (CURRENT_USERID will return a database username)
Discoverer worked OK in your case with the SYS_CONTEXT (.. CURRENT_USERID) because authentication is made by database user, probably.

Hi
See my answers below
1) Will we be able to re-use our 8.2 scripts (Functional and Load Testing) in 8.5 or 9.0, or will they require re-writing?
You can reuse the scripts as long as they don't have any VB in them, as the VB engined has been removed
2) Will we be able to continue to write our scripts in Functional Tester and play them back in the load tester (thin client) as we have been doing.
No OpenScript separates both scripts you will not even be able to see the script in the e-load interface
3) Are we forced to learn OpenScript and use OpenScript (either for 8.5 / 9.0 or in a soon upcoming release)?
Yes, e-tester support will end soon and will be replaced with OpenScript, OpenScript has been developed by the same team that did e-tester so changing from one tool to the other should not be difficult.
4) Will scripts created in OpenScript for Functional Testing, be usable in Load testing or will we need to create seperate scripts again.
No, there may be support for that in the future but not now.

Alex

Complete Java 2 Training Course

Hello
Has anyone tried Complete Java 2 Training Course by Deitel? The 5th edition is about $109 but I can get a 4th edition for about half of that. 4th ed is 2002 and I wonder how different it is. A self paced course may be a good way to go.
thanks,
Hal

I agree - seems pricey.
What's wrong with the on-line tutorials from Sun? They're free and self-paced. - MOD

Announce: Online struts training

It would be great to attend more advanced training on Struts. But maybe it
          is hard for you to get to the city of the presentation. What if you could
          from home attend 4 different published authors?
          What if additionally there were labs by "Best Training" as voted by JDJ?
          What if you could view the presentations, ask questions, do the labs and
          hear the presentation from your home?
          Announce: "*Best Practices in Struts - Web Training*" by Cekvenich, Husted,
          and Turner and a presentation by Momjian on PostgreSQL. (each a published

Calling a BPEL process from java (STRUTS)

Hi,
IÂ´ve a workspace where I have all the deployed bpel processes, and IÂ´ve other workspace with a Struts project. I deployed my Struts project in the OC4J Server where the BPEL processes are deployed.
IÂ´m trying to initialise Locator instance in a .java file. The Locator will search the bpel processes in the default domain. I get an exception when I run the project, dont know what IÂ´m doing wrong. (canÂ´t copy the exception from the Embedded OC4J Server)
THE CODE:
static Locator locator = null;
static String bpelDomain = "default";
static String bpelDomainPassword = "bpel";
static String orabpelPlatform = "oc4j_10g";
static String javaNamingFactoryInitial = "com.evermind.server.rmi.RMIInitialContextFactory";
static String javaNamingProviderUrl = "ormi://develc15:23791/orabpel";
static String javaNamingSecurityPrincipal = "admin";
static String javaNamingSecurityCredentials = "welcome";
static String dedicatedRmiContext = "true";
public static void invokeProcess(String processName, String operationName, String sXml)
try
Properties props = new java.util.Properties();
props.setProperty("orabpel.platform",orabpelPlatform);
props.setProperty("java.naming.factory.initial",javaNamingFactoryInitial);
props.setProperty("java.naming.provider.url",javaNamingProviderUrl);
props.setProperty("java.naming.security.principal",javaNamingSecurityPrincipal);
props.setProperty("java.naming.security.credentials",javaNamingSecurityCredentials);
props.setProperty("dedicated.rmicontext", dedicatedRmiContext);
locator = new Locator(bpelDomain, bpelDomainPassword,props);
} catch (Exception r)
r.printStackTrace();

I tried to call an async BPEL process from simple Java client. The only difference that I see in your code and mine is, that I haven't specified the "orabpelPlatform" and "dedicatedRMIContext" properties. Also, another diferenece is the ProviderURL used. I have copied the settings as found under "samples/tutorial/102.InvokeProcess/rmi/Context.Properties".
While setting the properties use -
Context.INITIAL_FACTORY
Context.PROVIDER_URL
Context.SECURITY_PRINCIPAL
Context.SECURITY_CREDENTIALS
instead of specifying java.naming.xxxxxx class names.
Please check the file to see what are the Context properties set during installation for your BPEL PM. Use the same to define Properties to be passed as parameter in the Locator constructor.

New Open Source Project - Java, Struts, EJB

There is a new open source project called Centraview. This is an open source CRM/SFA application which can provide a business a full view of their enterprise from lead generation, sales, contact management, project management and integrate into accounting. The development has been going on for more than a year now and they've now taking this open source, so there is alot of opportunity for Java developers to get involved with project that really takes advantage of Java technology. The system is built on the Struts framework and utilizes JBoss as the EJB container, the back-end database is MySQL although there is some initiatives to look at DB abstraction. Anyway here's the link:
http://sourceforge.net/projects/centraview/
Anyway I decided after examining Centraview, that we're not going to be building our own, but using Centraview and it's nice to know we can take part in development and understand the inner workings, so we never limit ourselves.

Presumably you mean GUI and not web.
I have used AutoIt to drive GUI window applications.
[http://www.autoitscript.com/autoit3/]
Seemed pretty easy when I used it. It had a recorder.
On windows I believe you can also use "script host" and the newer powershell but I have used those.
You could also look at the java Robot class or whatever it is called.

Hey henhowc,
Kst8no1 is correct here: last week's staggered midnight opening events were specific to Call of Duty: Advanced Warfare due to its Day Zero promotion. There's always a possibility other developers may choose to follow suit the future though, so the best advice we can give would be to keep an eye on our midnight opening announcements on BestBuy.com for updates.
Thanks for your pre-ordering with us!

Hey thanks again.
The part of the article that talks about "which Discovery sytem do I have" kind of made it clear.
I heard SAP does the remote access kind of a thing with their R/3 systems , something called the IDES access , and that made me thinking if they do something similar with MII as well.
I guess they don't.
Thanks.
