Can't access env-entry s in init()

          Hi all,
          How can I access the <env-entry>'s I have in my deployment descriptor in my servlet's
          "init()" method? I'm not getting the values from there.
          Should I pass parameters to my "new InitialContext(...)" call? What params do
          I pass?
          Thanks,
          Boogie

Then it is probably a WebLogic bug.

Accessing env-entry value from a java class

Hi,
I have my env-entry element declared in ejb-jar.xml like this
<env-entry>
<env-entry-name>ConfigFile</env-entry-name>
<env-entry-type>java.lang.String</env-entry-type>
<env-entry-value>centaur</env-entry-value>
</env-entry>
and if I access that value from the EJB of that ejb-jar.xml, it is giving the right value. But when I am trying to retrieve the same from a java class, that is throwing exception "javax.naming.NameNotFoundException: Unable to resolve 'ConfigFile' Resolved ; remaining name 'ConfigFile'"
I think this is because env-entry has access to only EJB to maintain security?
or can env-entry elemenets cab be accessed outside the EJB and some thing I am doing wrong here?
can some one help me here?

Hey Frank,
The JCo, DI API and DB are all on PL 18. I have found that the error only occurs for one business partner, and that business partner had a service contract added to it the day before the error started to occur. Also the business partner in question is the only business partner with a service contract which would explain why it is the only one experiencing these problems. It could be a coincidence but I will let you know what the outcome is.

Accessing env-entry from out side bean

But when I am trying to retrieve the same from a java class, that is throwing exception "javax.naming.NameNotFoundException: Unable to resolve 'ConfigFile' Resolved ; remaining name 'ConfigFile'"
          I think this is because env-entry has access to only EJB or MDB to maintain security?

          can some one help me here?

The java:comp/env namespace is local to the J2EE component (ie the EJB).
          You could certainly have a business method that returned the value and call the business method from a java class.
          Or your EJB could lookup the env-entry in JNDI and store it in another data structure.

Issue with [env-entry] element in web.xml

I know it's possible to define [env-entry] elements in web.xml for environment
properties of a web application. But how do you access [env-entry] elements from
classes that do not exist within a web application? In other words, this is my
problem:
I have an EAR file, enterprise.ear, which contains the following...
employee.jar
employeeSearchEJB.jar
webApp1.war
META-INF/
application.xml
The employee.jar file is a utility archive that contains common classes, one of
which is a class called LogManager. LogManager needs to read environment properties
in order to initialize itself. Currently, LogManager reads these properties from
a property file, and therefore it needs to know the name of the property file
in order to access it. I dont like this approach because I'm forced to hard-code
the name of the property file in LogManager. I would rather leverage the power
of J2EE deployment descriptors and use the [env-entry] element to define the environment
properties for the LogManager class. Then, I would simply use JNDI to get the
values of the [env-entry] elements without ever having to specify their location
aside from the default JNDI context; java:comp/env, which is standard anyway.
The problem I'm having is that you can define the [env-entry] element in only
2 types of deployment descriptors; namely, web.xml and ejb-jar.xml, neither of
which are available to LogManager because LogManager exists at the EAR root level.
I was hoping application.xml supported the [env-entry] element, but it doesn't.
Any suggestions?

SAF,
I am not sure if this applies to you situation but if you create an initial context
instance and then grab the value using the jndi name within that context then
you should be able to grab that environment variable.
I have a helper class that is used as part of a deployed application. The helper
class doesn't have access to the Servlet context but it is created as part of
the application workflow. When it gets initiated it grabs an env-entry created
in the web.xml deployment descriptor to find the default url for a content path.
After I create an initialContext, I perform a initContext.lookup("jndi.env.entry.here")
where "jndi.env.entry.here" is the name specified in the env-entry tag.
This returns the value of the entry.
This works under both Jrun and Weblogic so my guess is it should work for you.
Again, I am assuming that your class will at least be able to grab a context
object to communicate back to the server.
Hope this helps,
Troy

Can not access cache in entry processor

Why the cache where the entry object exists can not be accessed in entry processor?
The calculation in entry processor will not always be one grid object operation.
One object would be related to other objects.
If we could not do such thing in entry processor, we have to process calculation outside of the entry processor. However, caculation out of grid would not be a very efficient way for generating result.
Does anyone have good idea on this?

Hi, Robert,
I understood your meaning.
Invocable is an alternative solution for processing data. Use it outside of entry-processor, no dead lock would happen.
I paste piece of my code here. Following codes can not work properly. Just like you said, can not wait for result inside of entry-processor. My original purpose is that get "Nation" property from another data object. Now, I only can do it outside of entry-processor.
public class UpdateFxProcessor extends AbstractProcessor {
     public Object process(Entry entry) {
          HtWsMeasuresUsdFx hfx = (HtWsMeasuresUsdFx)entry.getValue();
     InvocationService service = (InvocationService)
CacheFactory.getConfigurableCacheFactory()
.ensureService("InvocationService");
     Map map = service.query(new NationInvocable(hfx.getWsNationCode()), null);
     String nation= (String)map.get(service.getCluster().getLocalMember());
          hfx.setNation(nation);
// ... other logics for calculating hfx....
          return null;
My data grid environment will store more than 10 million HtWsMeasuresUsdFx objects. I hope that calculation on these objects could be executed in parallel. Maybe I misunderstood the function of entry-processor. If we use Invocable outside of entry-processor, it is hard to control its calculation in parallel, isn't it?

OK,
Let's say I have to intialize Environment, and call method initEnvironment() in Applet's init(). Environment class:
class Environment
     private KeyStore keyStore;
     private Enumeration<String> aliases;
     public void initEnvironment() {
          Security.addProvider(new sun.security.mscapi.SunMSCAPI());
          keyStore = KeyStore.getInstance("Windows-MY");
          keyStore.load(null);
          aliases = keyStore.aliases();
}Applet is signed, I trust signer.
Since Applet is signed I'm able to overwrite existing .java.policy under user.home.
This doesn't work if I don't have .java.policy:
grant {
permission java.security.SecurityPermission "insertProvider.SunMSCAPI";
permission java.security.SecurityPermission "authProvider.SunMSCAPI";
permission java.util.PropertyPermission "jsr105Provider", "read";
permission java.util.PropertyPermission "com.sun.xml.internal.ws.api.pipe.Fiber.serialize", "read";
permission java.lang.RuntimePermission "setContextClassLoader";
permission java.util.PropertyPermission "com.sun.xml.internal.ws.api.streaming.XMLStreamWriterFactory.noPool", "read";

permission java.lang.RuntimePermission "accessClassInPackage.com.sun.xml.internal.ws.fault";
permission java.util.PropertyPermission "com.sun.xml.internal.ws.api.streaming.XMLStreamWriterFactory.woodstox", "read";
};P.S.
Does it make sense to be able to make changes to file system and not be able to make actions from above policy?!?!

Env-entry reachable from more than one bean

Is it possible to reach env-entries of one session-bean from another session-bean within same ejb-jar.xml?
Or is the only way to write them twice, once per each bean.

Greetings,
Is it possible to reach env-entries of one
session-bean from another session-bean within same
ejb-jar.xml?In theory, a JNDI namespace is hierarchical (a tree structure - like a filesystem) - and a server typically maintains a global namespace - so as long as your bean knows the lookup name of the entry it can be accessed regardless of the locality of the bean (ie. it may even exist in a separate application running on the same server!). However...
Or is the only way to write them twice, once per each
bean.The purpose of environment entries is to provide "post-compile time" customization to your beans and so ideally each bean should have it's own env-entries specific to it's needs. Additionally, depending on your vendor implementation private namespaces for env-entries might be provided and/or you may also get assembly/deployment errors for beans performing lookups against the namespace for which assembly mappings were not provided. In these cases you will have to devise a mechanism for the passing the env information between your beans (since the specification prohibits beans from modifying their runtime environments. ':-o ).
I hope this helpful.

Env-entry-mapping in orion-application-client not available in JNDI lookup

I have an application client module in my EAR file that I've configured to auto-start.
It has a few env-entry defined in it's application-client.xml.
When I deploy the EAR file to OC4J 10.1.3, the application client module gets started and can access these env-entry properties from its JNDIContext.
Now, comes the problem. During the deployment process, I edit the Deployment Plan, and change the env-entry property values, and then deploy the application.
However, the application client module still gets the original values when it does the JNDI lookups of those env-entry names.
I have checked to see that OC4J creates an orion-application-client.xml during deployment and it shows the env-entry-mapping elements with the updated values.
Why is the JNDI lookup returning the values from application-client.xml and not the overriden values set in orion-application-client.xml?
I have tried this on OC4J 10.1.3, as well as 10.1.3.1.0 - got same behavior.
Is this a bug in OC4J? This seems to work fine with ejb modules, but not application client modules.
Thanks,
Kalpak

Avi!
Of course, I had tried it before I wrote the question. I put the modified xml file into the application area. After that AS restarts OC4J instance. And then I find my xml without any changes I made! I tried to do the same thing from the AS console. The same!

Global env-entry JNDI variables space for same ejb-jar.xml file

[Software]
jboss4.0.5
jdk 1.5
[Problem]
Is there any global <env-entry> tag for a Single EJB Module. Is there any way by which the JNDI variable can be accessed by all the modules except by binding the variables in the JNDI explixity in the code
Thanks in advance
CSJakharia

Unfortunately not. The EJB specification has always scoped the component environment
(java:comp/env) as a private environment for each EJB. The advantage is you can
assign entries within each bean easily without worrying about clashing with names selected
for other beans in the ejb-jar. That eases the process of assembling beans developed
separately into one ejb-jar since there is no possibility that their component environments
will clash.
However, the downside is just what you're pointing out, which is that in many cases
developers prefer to define a single dependency that is shared among all the
beans in the ejb module. That is the behavior of the component environment in a
web application.
We'll be looking into ways to simplify this for ejbs in a future revision of the specification.

Updated env-entries in web.xml

          We are using WLS 5.1 SP10.
          In a web-application we like to have some parameters (related to the webapp as
          a whole) which can easily be changed (without having to restart the server).
          What is the best way to do that?
          I was thinking of env-entries.
          But when I change them the web.xml is not reloaded and the changes have no affect.
          Is dynamic reload of web.xml possible under WLS5.1 SP10?
          When should env-entries be used, and when init-params?
          Init-params seems to be servlet(JSP) related, while the environment entries affect
          the web-app environment. Are there other elements to take in consideration?
          In the doc I found no real explanation of when to use what...
          Any help would be appreciated,
          Frederic

Hi,
these are only configurations and don't cause a harm or use resources. So I suggest to leave them in just in case yu need them later

Weblogic jndi env entries

Hi,
I have a little problem. i have a webapplication deployed in weblogic 6.1, now i tried to create an env entriy (in the web.xml) and now i want to access this env entry from within my jsp page.
I have created a new InitialContext and then just called
System.out.println(ctx.lookup("myenv"));
But weblogi can't find the environment myenv. -> NameNotFoundException
is there another way to access those env entries like in j2ee "java:comp/env/myenv" ????

everything ok now..it is "java:comp/env"! i had to reinstall weblogic before it worked.. don't ask me why.
