ejb in other application ?
Hellu, What (extra) do I need to do to be able to call a bean in another application (from a servlet/bean in another application)? When I call the bean in the same application, everything is ok. However when I do the same in another application, Orion isn't able to find the Bean. Hh I think I need to configure something extra, but can't find what. Some help please ? Eddie
Re: Paged search results
My first thought is that a cache should not be stored in a session, since that would only be available in that session and "cannot" be shared... Better to store a searchresult in the application object ( if the result is static and is the same for all users). If the searchresult is specific to a certain user, then you could store it in a session. For multibrowser usage, there will be separate sessions for those. There is probably a way to get them to use the same session, but I haven't tried this. In this case I suggest a hashtable in the application object and an id string ( key in hashtable ) in the session. Hope this at least gives you a couple of ideas on how to get started. regards Johan - Original Message - From: "Holden Glova" <[EMAIL PROTECTED]> To: "Orion-Interest" <[EMAIL PROTECTED]> Sent: Wednesday, March 28, 2001 6:19 AM Subject: Paged search results > Hi all, > > Perhaps this is slightly off topic and > if so, I apologize and feel free to > ignore this.

Hi all, Perhaps this is slightly off topic and if so, I apologize and feel free to ignore this. My knowledge of j2ee is not high but I would like to know the best way to handle this with of course, minimal complexity. I am not sure where else I can find information on this subject from knowledgeable people though, so here goes. We are wondering what the best approach would be move through a collection of page results that come back from a search. We have thought about using sessions to cache the results and help keep track of what the current result view consists of, but we are not sure if this is the best way to handle something like this. Some things that come to mind are what would happen if we have multiple browsers open trying to perform different searches at the same time, would we need a separate SessionBean to cache these results in? What could be some of the advantages and disadvantages of using sessions for this problem? Can anyone point me to some other ways of approaching this problem aside from using sessions?

Sounds like the flush=true is committing the response stream before you add teh cookie. This is not a bug.

Cookie creation bug (?) for servlet-including jsp files
I am working on a web-app (powered by Orion 1.4.5) that uses a jsp page with several Java servlets included within it that do the more complex computations. The jsp file has lines like: "" that load the servlets. This does a request on the servlet and inserts the HTML they return at the include point. The problem is that in one of the servlets I am trying to create some cookies using the standard HttpServletResponse.addCookie(new Cookie(name, val)) code. If I run the servlet directly without embedding it in a jsp file then the cookies get created just fine. But when I try to execute the servlet from within the jsp file, then the cookies do not get created, even though I know that the addCookie() method is being reached and executed. This same jsp and servlet combination worked and created the cookies without problems when run under Allaire's JRun 2.3. Is this an Orion bug? And can anyone think of a work around that won't involve massive changes to how the code is organized? - Mike

Collection Finders With Entity Argument Always Return Empty Collection
My last shred of sanity is vapourizing as I type. I've spent several
fruitless days trying to work around Orion 1.4.7's inability to generate a
working finder method that takes an Entity reference as an argument. When I
finish composing this message I think I'll gibber under my desk for a while.
Help.
Among many others, I've got two Entity EJBs built: CatalogEJB and
CatalogEntryEJB. Both are CMP entities. CatalogEntryEJB has a working 1:1
CMR uni-directional relationship to CatalogEJB. I've defined the following
finder method in the home interface of CatalogEntryEJB so that a CatalogEJB
instance can find all the CatalogEntryEJB instances that 'belong' to it:
Collection findByCatalog(Catalog catalog)
throws EJBException, RemoteException, FinderException;
Once deployed, the descriptor entry for CatalogEntryEJB contains the
following:
CatalogEntryEJB
findByAll
CatalogEntryEJB
findByCatalog
com.canlink.components.model.catalog.Catalog
When called from a method in CatalogEJB, the findByAll method works fine,
returning all the CatalogEntryEJB instances in existence. However, the
findByCatalog method always returns an empty Collection, no matter what may
exist in the database. There is never any exception thown, it just always
returns an empty Collection. If I manually execute the generated SQL
statement, I do in fact get the appropriate results.
Investigating deeper, I've aimed Together Control Center's debugger at this
bit of the generated code for the CatalogEntryEJB Home's findByCatalog
method:
java.sql.PreparedStatement statement = connection.getCustomStatement("select
CatalogEntryEJB.identity, CatalogEntryEJB.catalogIdentity,
CatalogEntryEJB.catalogLocale, CatalogEntryEJB.label,
CatalogEntryEJB.targetRoleIdentity, CatalogEntryEJB.referenceidentity,
CatalogEntryEJB.price, CatalogEntryEJB.discountRate,
CatalogEntryEJB.parentreferenceidentity, CatalogEntryEJB.referenceTypeInt,
CatalogEntryEJB.productCode, CatalogEntryEJB.description,
CatalogEntryEJB.extendedDescription, CatalogEntryEJB.listIndex,
CatalogEntryEJB.created, CatalogEntryEJB.creator, CatalogEntryEJB.modified,
CatalogEntryEJB.modifier from CatalogEntryEJB where
CatalogEntryEJB.catalogIdentity = ? and CatalogEntryEJB.catalogLocale = ?");
try {
com.canlink.components.base.LocalizedEntityPK primaryKey398 =
argument0 == null ? null :
((com.canlink.components.base.LocalizedEntityPK)
argument0.getPrimaryKey());
{
if (primaryKey398 == null) {
if (((java.util.Locale) null) == null) statement.setNull(1,
java.sql.Types.VARCHAR);
else
statement.setString(1,
com.evermind.util.ObjectUtils.toString(((java.util.Locale) null)));
if (((java.lang.String) null) == null) statement.setNull(2,
java.sql.Types.VARCHAR);
else
statement.setString(2, ((java.lang.String) null));
}
else {
if (primaryKey398.locale == null) statement.setNull(1,
java.sql.Types.VARCHAR);
else
statement.setString(1,
com.evermind.util.ObjectUtils.toString(primaryKey398.locale));
if (primaryKey398.identity == null) statement.setNull(2,
java.sql.Types.VARCHAR);
else
statement.setString(2, primaryKey398.identity);
}
}
}
finally {
}
java.sql.ResultSet set = statement.executeQuery();
while (set.next()) {
}
Although I can't inspect anything while debugging this code (presumably
because Orion compiles it without debugging info), I can step through it and
observe that primaryKey398 is not null, and that both appropriate
statement.setString() methods are being called. I can also observer that
much to my disappointment, the ResultSet never returns true from its next()
method since the contents of the while{} block at the end of this snippet is
never executed.
Interestingly, the generated code (below) for the findByAll method always
works: the ResultSet contains all the extant CatalogEntryEJB rows, and the
while{} block gets executed for each one.
java.sql.PreparedStatement statement = connection.getCustomStatement("select
CatalogEntryEJB.identity, CatalogEntryEJB.catalogIdentity,
CatalogEntryEJB.catalogLocale, CatalogEntryEJB.label,
CatalogEntryEJB.targetRoleIdentity, CatalogEntryEJB.referenceidentity,
CatalogEntryEJB.price, CatalogEntryEJB.discountRate,
CatalogEntryEJB.parentreferenceidentity, CatalogEntryEJB.referenceTypeInt,
CatalogEntryEJB.productCode, CatalogEntryEJB.description,
CatalogEntryEJB.extendedDescription, CatalogEntryEJB.listIndex,
CatalogEntryEJB.created, CatalogEntryEJB.creator, CatalogEntryEJB.modified,
CatalogEntryEJB.modifier from CatalogEntryEJB");
java.sql.ResultSet set = statement.executeQuery();
while (set.next()) {
...
}

There is no workaround. If they do not fix this bug, we will need to deploy on another

RE: java.lang.OutOfMemoryError
We found we could force passivation in the later orion builds - not sure exactly whch builds it works in, but its OK in 1.4.7. Create a directory called orion in the root of your ejb jar (i.e. as a sibling of your META-INF directory). In the orion folder, create a file orion-ejb-jar.xml (The easy way is to copy the one that was auto created on a previous deployment - look in the $ORION_ROOT\application-deployments and the correct sub-folder.) Edit the file so that there is a max-instances="100" attribute on each of the entity-deployment entities. Delete the previous deployment directory (otherwise the new file will not be copied over), and repackage/deploy. Seems to work for us.

Ah yes, I think you're right. I think that I tried to get around this by copying a
sample application-client.xml file into META-INF on the client side, and that had no
effect at all. Perhaps the contents did not make Orion happy.

Serious indeed. What are you doing for a work-around?
Bugs aside, the amount of work required to deploy code on Orion is pretty
mind-boggling. That, combined with the lack of detailed documentation, is
disasterous. I've only had experience with one other J2EE server, JBoss. JBoss can
be a real pain to set up, and like Orion has useless or missing error messages, but at
least deployment is relatively painless. Orion is my private nightmare - I've wasted
days trying to get the simplest things to work, like this JNDI lookup. I *want* to
use Orion, but it doesn't want me to use it!

Re: Oracle Clob Prob
Claus,
If you use a StringBuffer instead of a String to copy the bytes into, you won't
be allocating/deallocating as much memory.

RE: Orion + IE + HTTPS = Trouble
We have experienced session problems with both Bluestone's product and Orion. This only happened to us when using IE 5.5.

EJBUser & User
Hi people, I'm trying to figure out how to set up a usermanager for my application, and since the User is supposed to be an EJB, I'm having a look at the EJBUserManager. But I can't figure out why the User interface is not a superinterface of the EJBUser interface, and the EJBUSerManager methods return a User interface. Any clue? Is EJBUser ejbUser = (EJBUser) ejbUserManager.getUser(username) where ejbUserManager is my EJBUserManager supposed to work? Greetings Diego
