SV: Re[2]: R: R: frustrated - jdbc: No suitable driver
You shouls check out the getConnection implementation on the datasource. It gets a reference it pass on to the client, so the client need to have the jdbc interfaces to do this, but it dont need the database drivers. It works much like the same way as an entitybean works (datasources)... Have fun. Klaus -Opprinnelig melding- Fra: Jeff Schnitzer [mailto:[EMAIL PROTECTED]] Sendt: 5. februar 2001 12:17 Til: Orion-Interest Emne: RE: Re[2]: R: R: frustrated - jdbc: No suitable driver I'm fully prepared to believe that my understanding of how this works is wrong, but if so it raises quite a few questions for me. Connection, Statement, ResultSet, etc are just interfaces; something must implement them. Normally they are implemented by the JDBC driver, thus allowing the client to communicate with the database using whatever the database uses asa native wire protocol. We have an application client which we want to communicate with the database using JDBC. If we want to use the database's native wire protocol to communicate from the client box to the database box, the JDBC drivers *must* be loaded into the client's VM and used. Alternatively, the app server could act as an intermediary, providing a proxy JDBC interface to the application client and making JDBC calls into the real JDBC driver within the application server. This would obviate the need for the database's JDBC driver on the client, but it would also require inventing a whole new wire protocol for this middle link... sending partial result sets in chunks, maybe caching query results in the client, etc. So now I'm thinking, that sounds painful, but it's possible. It's not like writing an app server is supposed to be *easy* or anything :-) No, Karl and Magnus are supposed to suffer so that it's easy for *us* to write applications :-) But a casual purusal of the decompiled Orion source code (that can be made out through the obfuscation, which is quite a bit) turns up no evidence of such a proxy. In fact, it looks very much like this is not the case. Getting more curious, I checked the JBoss source tree, and while I can't be sure in such a quick study, it doesn't look like there is any sort of intelligent JDBC proxy in that server either. Am I just missing it, and all app servers implement such a proxy? Or is it just WebLogic - allowing the behavior described in the original post? Or is WebLogic doing http-type classloading to get the JDBC driver into the client (a prospect I am considering less likely the more I think about it)?

SV: When using autonumber for the primarykey...
That is right...
The Counter.jar EJB marks a pool of ids it can deliver, just as the
databases identity column does it to keep performance.
If you need perfectly sequel numbers you have to implement your own EJB to
do so. But then you will get a performance hit on 5-10 inserts a second or
so. When you do the buffering Counter.jar does its quite nice performance :)
And for the comment it cant be right...It is right, this is the way you do
identity columnts in ejb with performance and so on. If you need the
database to do it for you, there is only one choice...That is BMP with the
implementation of post create.
Inserts is generally not as performance critic as selects, since inserts
usually is less data than the selects going through thte databases... That
is why you seldom has to tune an insert :)

Here's the relevant code from CounterEJB.java:
public String ejbCreate(String name)
throws CreateException
{
this.name = name;
currentID = 1L;
currentPrivateID = 0L;
return null;
}
public long getNextID()
{
if(currentPrivateID == 0L)
currentPrivateID = currentID;
for(; currentPrivateID >= currentID; currentID += 10L);
return currentPrivateID++;
}
currentPrivateID is not an entity field.

You will have to define the jdbc connection in the datasource configuration
file on the appserver though.
The client should never use any jdbc directly :)
The Entity beans can be mapped using cmp or bmp and the lookup through the
JNDI context for the suitable connection instance is
done through the J2EE context classes as explained by Burr..
A normal method to do this is (inside an EJB in this example):
Connection conn = null;
try {
InitialContext ic = new InitialContext();
/* Here is the JNDI name...check orions data-sources.xml
* file in the config directory to see examples with hsql
*/And note that you should prolly choose to use the pooled-location
name
DataSource ds (DataSource)ic.lookup("jdbc/ProdObjectSpacePooledDS");
conn = ds.getConnection();
} catch (Exception ex) {
throw new EJBException(ex);
}
// .. do some JDBC stuff
conn.close();

Hey Tom,
Potentially silly question (somewhat new to Orion but I've used a few other

I disagree. Part of the benefit of a DataSource is that it can abstract
the actual driver or database being used. If I can ask a DataSource for
a database connection and not have to care about which client-side
driver to load, and (less practically), even what rdbms i am using.
That way, the app server can change databases, drivers, even vendors
without its clients being aware.
I experienced this issue porting an app from WebLogic. I used the same
schema and sql with SQL Server and Postgres on WebLogic. My client
application (which both queried and populated the database) never
changed. It just got a Context from the app server, gfot a DataSource
by name, then got plain old JDBC Connections from there. No JDBC
drivers at all.
I think that is a useful layer.

SV: When using autonumber for the primarykey...
One approach is to use bean managed persistence and implement the
ejbPostCreate method to retrieve the generated id into the instanciated
bean.
Its a slow approach but the only one you can get working, since the ejb spec
does not handle identity fields.
If you want to use identity fields and have control over the db-schema you
can use the Counter ejb from evermind or write your own identity generator
bean that generates new ints for tables. This is the approach you have to
use with containermanaged persistence...
Good luck.

If it's actually an autonumber field (at least with SQL Server), just insert
the rest of the fields (not including the autonumbered field), e.g.
(presuming your table includes First_Name,Last_Name, and an
autonumber...say, a Customer_ID field):
"INSERT INTO tblMyData(First_Name,Last_Name) VALUES('Sam','Adams')"
The table will automatically generate the autonumber for the ID field, hence
the name ;-). Additionally, if you *try* to insert a value into the
autonumber field, SQL Server will generate an error. I'm not sure whether
there may be different behaviors in different DBs...anyone?

SV: Disregard: Re: BUG: Can't cast RMI interfaces in 1.4.5
This is not a bug :)
You should use the narrow method to do this, or you are not ejb2.0
compatible or corba to be more spesific.
Here is an example on how i would do it:
* SNIP START
Context ctx = new InitialContext();
MyRemoteHome home = (MyRemoteHome)
PortableRemoteObject.narrow(ctx.lookup("java:comp/env/myserver"),
MyRemoteHome.class);
MyRemote remote = home.create(); // for session beans ofcourse :)
* SNIP END
This is the way you should do itBtw to be corba aware with session beans
do a remote.remove() when done with the session bean in the client...Many
dont do this, and then they get humongus memory problems very fast
:)remember corba dont do distributed GC like RMI does
Now have fun!! Hope you get it working :)

There is one thing you have to remember conserning sybases JDBC driver. You have to install the procedures (a script file coming with the driver) before it works correctly. Other then that i have been using 11.5.2 and 11.9.2 + 12.0 without any problems, actualy I am impressed by how well the JDBC driver works :) Klaus -Opprinnelig melding- Fra: Chris Bartling [mailto:[EMAIL PROTECTED]] Sendt: 20. januar 2001 23:52 Til: Orion-Interest Emne: RE: Sybase experience anyone?

SV: Getting the home interface of another EJB from within an EJB
You work with EJBs inside another EJB the same way as you do inside a JSP
Remember you have to use the JNDI name, not the home interface name, so a
lookup("ejbSomeExample") will ofcourse return the home interface :)
Hope this helps (ps remember ejb-refs to the objects you wish to use from
the bean you are calling from or it will not work..

Emne: Getting the home interface of another EJB from within an EJB
>From inside an entity bean you can get hold of your Home interface by
calling
myBeansEntityContext.getEJBHome()
but how do I get hold of the home interface of _another_ bean?
I assume this requires some kind of lookup. In JSP files one would simply
use "new InitialContext()" and perform a lookup on this context, but if I do
so within an EJB, I am not able to find any home interfaces at all - I get a
NameNotFoundException.
Now, is it really necessary to go all the way and get an InitialContext by
setting up environment properties and creating an InitialContext from these
plus adding an "application-client.xml" to the deployment?? - After all
I am still inside an EJB...
Any hints would be appreciated.

SV: large field bug ??
Yes its possible, but not very wise...
What happens when you want to make a field that is a varchar??
A blob is a Binary Large OBject right, if you have the text datatype in your
database this is a way better sollution, but still not a good one
Varchar is the best mapping for string.
If you use blobs on every one string you store in the database its ok...For
instance :
name: blob
address: blob
sex: blob
See my point?
What you might want to do is make your own BigString that is mapped into an
blob in the database, if you want to do this. Look at the oracle-schema to
find how to do this.

Some thoughts...
You are right, that such a work-around would work, but having to keep your
Strings stored in memory as Objects i not very nice - can't the mapping be
changed, so Strings are mapped to Blobs...?
If not, I would use StringBuffer (which is probably mapped to BLOB) instead
of Object to store my Strings.

had that problem
it's a mapping problem... (oracle-schema)
Strings get Mapped to varchars(size)...
They get chopped at size chars...
the only solution is to declare the field as java.lang.Object
then use it as string
public Object name;
public void setName(String name)
{
this.name = name;
}
public String getName()
{
return name.toString();

SV: JSP vs PHP
Very true. PHP is a strange mix between java, perl and c++, but it has some very interesting plugins that can speed development. PHP can allso use javaobjects :) that is a nice feature.Even EJB. Still when youve done a couple of JSP projects you are likely to have built yourself a set of good modules of some sort to use in JSP so i dont think this is something to think about. If you know Java and not PHP, it is extremely easy to learn yourself JSP. The speed of PHP comes only in 1 (maby two) configurations, one is if you integrate it into apache so it dont run it as cgi, or maby (havent tested) when you compile pure java integration (not cgi)... Somehow i have met some distros that will only run this thing as cgi :P Still on a server with lots of memory and a good JSP engine i dont think you will see any speed differences on solaris or windowsLinux still have a small issue with speed and memory usage in the vm, this will prolly get better pretty soon :) JSP engines exists for virtually any webserver out there on any platform (allmost) so its a very good choice to know this technology, and i see my own customers throwing away those old ASP engines and porting applications over to JSP all the time... And for those who want to flame me for not liking PHP i can only comment: I like PHP but i like JSP and its taglibs a bit better, especialy because there are loads of documentation and a very easy learning how to use if you are proficient in Java + you have an excelent server development spesification called J2EE that is starting to get widely used now.

We use Orion and Sybase EAServer 3.6.1 wich are excelent (except from Orions applet jndi bug which is horrible and critical for our environment, thats the only reason why we went to Sybase J2EE certed server, yepp one of the four that has the CERT (not the licence, licence dont mean anything, its the cert that means anything)) If orion wants to get through the J2EE test suite they have a lot to do, amongst other things corba has to be supported for the ejb2.0 spec and so on. But hey its a good alternative anyways if you only drive web applications, and if you have dicipline enough to keep within the spec when making your applications even if you meet bugs and have to do workarounds. In the long run you will probably get a better server platform for all but the standard have to get some time to stabilize (this is a quite new technology, so things have to stabilize a bit before vendors have time to cert their servers and get up to date). Just think about it, EJB1.1 spec isnt to old, and now EJB2.0 is coming fast (with huge mods), what should a vendor do, every one wants to be the first with ejb2.0 support and get the publicity for that + be a contender in the race, and certing for them means to stop at their development branch and do "bugfixing and mods" to the existing code to get the test suite to run flawlessly. Its not a difficult choice when customers are screaming for new versions :) I do think we get atleast another year with "chewing in" and accepting the shortcomings of some servers out there. When it comes to the pricing parts ofcourse there are differences. But hey you choose after what your boss desside :), and if you are on a project that dont need good support and documentation, you can choose Orion, but if you are working on a high scale project that will need to be scalable and have a support system that responds fast + engeneers that can come on site to fix up in your problems, you choose someone else. If you need to use applets or webstart applications you choose someone who have got a client library :) since its not cool downloading an applet containing lots of useless jars and takes forever to run when you only really need a thin client driver. ¨ PS. One of the four largest application server vendors is Sybase (see http://my.sybase.com/detail?id=1009721)... Still i allso think prices on some application servers are a bit stiff yes, but look what they have support for (some of them), look at the organization around the product, and look on the documentation. I was impressed printing out the programmers manual of EAS driving 730 A4 pages of usefull information. But if you dont need this, and you have the possibility in your project to solve everything yourself Orion has no competition, its just a big heap of server for the price :).. (There is never one side to any case) I would presume i got a flamebait here. But hey what are lists for! :) But still the best advice is to not get all fired up now before x-mas :) gota have a good holiday right! Merry x-mas everyone..

Youre right is flamebait :) I do use vi aswell, but for an enterprise editor that should save you work, JBuilder dont work, since there is no synchronization of remote/home/bean/deploymentdescriptor + no database generation of Containermanaged beans I can't see the point using that much money on an editor.

And they have an excelent deployment descriptor editor for EJB, but hey its not the deployment descriptor thats the prob, its all that code editing :) If anyone have any tips on IDEs that support synching of EJBs (remote, home, bean, pk, deployment-descriptor) pls post a note on this list :) My department is looking for one.

After looking on JBuilder 4 Enterprise im dissapointed. The editor is huge, but JSP support is really bad, + EJB support is virtually not there. For a påroduct that expensive i recomend you to stay FAR away from it, its not worth it. Visual Cafe is sold from webgain (See webgain studio, looks like a good package).. Forte Internet edition actually support Enterprise development just as good as JBuilder, only the CVS support in forte is good enough to work against a pserver, JBuilder dont have support for notification/edit-unedit + branching + some basic cvs commands like add and so on, so the CVS support JBuilder claims to have is just on paper nothing else.

Use optimistic locking.. All updated data gets a timestamp and all retrieved data keeps the timestampBefore update compare the timestamp, if its a match noone has done an update. If it dont match you should refuse the update and give the user a message about this. Problems with webbrowsers are many, and the worst is that you can never depend on the browser or whatever is within to participate in a transaction (since the browser fetch and forget..)

I agree with you, it's hard to find information on that subject. I've been reading this list and the sun J2EE interest for a couple of months now and am almost ready doing my first complete EJB / JSP app. The thing I found is as follows. It seems that by using a tag-lib you can use your EJB directly in your jsp's, but the general opinion in this list and others is that the way to do such things is by creating 'common' java beans or classes to use with the tags in the jsp. These classes than refrence stateful or stateless session beans, which in turn reference the entity beans. sven -- == Sven E. van 't Veer http://www.cachoeiro.net Java Developer [EMAIL PROTECTED] ==
SV: Newbie Q: Can't find bean?
Here is an example of a bean lookup method:
private SomeEntityHome getSomeEntityHome()throws NamingException {
Context context = new InitialContext();
SomeEntityHome home = (SomeEntityHome)PortableRemoteObject.narrow(
context.lookup("java:comp/env/ejb/SomeEntity"),
SomeEntityHome.class);
return home;
}
This one should be usable :)
Then its ready to call findermethods and so on.For instance, to fine a
row in the database based on the pk:
try {
SomeEntityHome home = getSomeEntityHome();
SomeEntity remote = home.findByPrimaryKey(new SomeEntityPK(34));
catch (NamingException ne) {}
The JSP page can be coded just the same way as anything, only you dont have
to give any urls or providers and so on
to do it (if youre in the same vm/applicationserver) the ejb tag library i
mentioned earlier use this stuff inside the tag lib so the JSP code gets a
whole lot cleaner...

Emne: Re: Newbie Q: Can't find bean?
Thanks for your reply Robert, however I don't really feel it's fair
for you to have judged me ignorant of both Java and the J2EE in
general. I've done quite a bit of development with session beans, but
very little front-end (read JSP) development, and no EntityBean work,
as it wasn't supported by the EJB (1.0) containers we were working
with.
I've been through the JSP specification, and don't see anything in
there pertaining to how EJB are expected to be referenced. There is
section 2.13 describing the tag, and unfortunately
thought it would perhaps provide the needed functionality to automate
the bean lookup process.
In addition to the specification, I have a copy of the
Monson-Haefel book on Enterprise JavaBeans, but there is virtually no
mention of JSP-EJB interaction. I also spent some time earlier today
browsing JSP-centric books in the local bookstore, and found little
mention (usually about 1 paragraph) regarding EJB's.
Obviously, using the same method that is used in a Servlet allows me
to do what I need to do. I was simply looking for a way to skip that step.
I've seen some code posted to the list using tags in the
namespace, but haven't located any documentation for that particular
taglib. Perhaps you could be so good as to provide a link?
I'm in the process of downloading the Romans book, so perhaps that
will have the details I'm looking for.
Thanks for the pointer.

SV: JNDI Properties? Why EJB can't find another EJB..
A
possible problem is that you have forgot to add ejb-refs for the beans you wish
to use from your bean on your bean in the deployment descriptor (ejb-jar.xml) in
the bean jar file.
Then
you will get problems like this...

21:25Til: Orion-InterestEmne: JNDI Properties? Why EJB
can't find another EJB..
Strange thing..I posted this a couple of times
too. For some reason, I can NOT get my ejb to find another ejb. I am able
to find both ejbs from the servlet just fine, but I can't get one ejb to
use the other. Right now its one session trying to use another..but it
worries me when it comes to entity CMP use. I can only think of one
problem..that my ejb is not using the proper context. I do this in the
ejb:
Context context = new
InitialContext();
Object ref =
context.lookup("java:comp/env/ejb/EJB2");
That always throws a NamingException (or it
might be RemoteException..I can't remember which one it is that I always
get).
So, looking at the ejb example(s) with Orion, it
appears they all have a jndi.properties file with them, and I recall
reading in my ejb book that supposedly each vendor has different settings.
So the question is..do I need to create the context in one ejb with these
properties set? What is the code used to find one ejb from inside
another?
Thanks.
SV: Problems with EJB.
Check if you have added your correct ejb-refs in the web.xml file for the web application youre using the servlet from. The application-client.xml is for applets and applications, while the ejb-refs for servlets and jsps are defined in the web.xml file Hope its something like this and not a bug :) Have a nice weekend all!!

Hi there, I know that the question has been discussed here before, but I'm still a little confused about using MYSQL together with Orion. I've just downloaded mysql (version 3.23.22 beta) and the manual announces that mysql is now supporting transactions. If I understood it correctly, that would mean, that it should be possible to use mysql with entity beans. Am I right ?? What's confusing to me is the fact, that I only find news in mailing-list, that mysql is not supporting transactions. So I don't really now, if I can use mysql for entity beans. If not, which database would you suggest ?? It should work on NT and not be the most expensive one as I use it 'only' for writing my Master's Thesis. Thanks in advance, Michel

Hey.. I'm in the middle of developing the next version of our software platform for quality management and I have run into the following problem. The current development platform is ASP/COM but we are moving to J2EE and orionserver as our platform of choice. This is the problem When a user connects to the application, he chooses the company that he belongs to. This sets the context of the program to point to the database of that company and all operations are performed on that database. This if Company A has the database 'COMPANYA' and Company B has the database 'COMPANYB' users belonging to company A will be using the data in COMPANYA when performing EJB transactions, While Users in Company B will use COMPANYB when performing EJB transactions. Now the problem lies in my tellin the EJB to use database COMPANYB when a user from company B logs on and COMPANYA whem a user from company A logs on. Of course we are talking about hundreds and hopefully thousands of databases over time, so the context must be possible to switch easily. Can I do this someway with EJB, without resulting to the situation of modifying SQL sentences. Christian Kvalheim Qm plus __ Do You Yahoo!? Yahoo! Messenger - Talk while you surf!

SV: Ok. I feel dumb. Data Sources and MS SQL.
Actualy the windows version of the Sybase database is just as pleasant to work with as SQL server when you use the gui tools. And a bg advantage is that the jdbc driver that is made for the database is very pleasant to work with :), and when you need extra performance you can set the server on a Solaris machine and still use the windows admin tool against it for easy administration. ASE12 allso supports java in the database something that can be quite usefull if you have some routines that is neaded when you import data to make sure things are allright and so on. But don't missunderstand me, i allso use MS but not in a java environment (if I can get around it) Have fun!

Data Sources and MS SQL. Hey, there is nothing wrong with MS SQL Server and Win2K. As someone who is not a professional DBA and has no desire to become one (I like building things, not maintaining tempermenal third-party software systems), I find that SQL Server is by far the most pleasant of the big relational databases (Oracle, Sybase, DB2, Informix) to work with. The GUI tools work well, and most tuning is done automagically. The JDBC driver support is a bit of a problem, though. Conventional wisdom 'round here is that the JDBC-ODBC bridge is trouble and should be avoided in a production environment. It has native code and it will lock up the JVM periodically under heavy load. Someone on this list suggested this type IV driver: http://www.inetsoftware.de/English/Produkte/JDBC2/Default.htm The most basic license is $250, limited to 20 connections, and "may not be used with the Internet", whatever that means. Dunno if this restriction includes code running in an app server. Here is my data source: Make sure you put SQL Server in Mixed Authentication Mode. And take a vacation already!

SV: Using Orion As a Plugin to IIS for Servlets/JSPs
I have runned a full dynamic site with ASP, and it needed restart every week or it would crash because of an out of memory error, + if you look on the old benchmarks from the orion team you see that dynamic performance degrade over time with IIS 4.0, im not to confident about the IIS 5.0... Yes IIS is fast providing you use only static content, but when you use dynamic content, you get problems, and the reason IIS is fast for static content is because they hooked the server into the kernel of windows (smart). Same thing is coming to linux kernel pretty soon (the unstable versions have it allready)... But how many sites use static content. As long as i have been working, you will find maby 10% static content, and then dynamic performance is the thing that is important (and stability ofcourse).

It also does very well with dynamic content provided by ISAPI DLLs. Why do you believe it is "full of memory leaks"?

SV: Using Orion As a Plugin to IIS for Servlets/JSPs
Ofcourse it works, install suns com-rmi bridge and youre off.. But it will not work with isapi or any other filters.. You have to redirect inside the code... And for the one mentioning weblogic..You dont get any isapi filters for Weblogic either, you have to redirect calls the same way as you have to do to orion. It would be the same as to claim Apache has to get an isapi filter for IIS to serve php for IIS. Ok mention JRun that is a servlet engine and not a webserver, that one would ofcourse have a filter to run jsp and servlets inside IIS (or do a invis redirect) but thats not a webserver.. Ps: Orion is faster than IIS, so is most other webservers.. IIS is full of memory leaks and other stuff that make it bend when the load is really hard, and over time. Check the benchmarks on orion page, its done with microsofts own benchmark utility so :) Tip to use orion in cooperation with iis is: forget session tracking between the different servers, but you can easilly call webpages inside orion from iis and present them in the same frame or so. You can allso use Suns rmi-com bridge to call biz logic if this one can run with orionservers protocol. Have fun!

For what it's worth, here's what I've noticed while running Sun's jdk1.3 under Linux: When Orion is started, there are about a dozen jdk1.3 processess that start up simultaneously! Under jdk1.2.2, there was only one. As I modify the server.xml file - adding or dropping sites, the number of jdk1.3 instances increases dramatically. If I kill the first jdk1.3 instance started, they all terminate. Under jdk1.2.2, I've never noticed any additional processes start up. I don't know what these processes are doing, or why this happens, but it's just something that I've noticed, and the fact that the number of processes rapidly increases is pretty alarming. So... I went back to jdk1.2.2 for now, and that works fine. I'd suggest that maybe you can check out the number of processes running under NT, and see if perhaps you're experiencing something similar. -Dale

SV: Cascade Delete
Cascading delete is something that some database servers support, so far i havent seen anywhere that Orion is to support that in the buissiness layer.

When i delete the ejb by ejbobject.remove() method the dependent objects and relationship entries are not deleted from the database. Should this not be done automatically by the app server.

Hi i have just deployed a stateless session bean to orion 1.2.9. My
question
is how do you access the bean from a client? In the service console i make
a
client app to the bean i want, and in that directory a make a simple client
that looks up to the bean with this code:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.ApplicationInit
ia
lContextFactory");
env.put(Context.PROVIDER_URL,"ormi://localhost/Test2");
env.put(Context.SECURITY_PRINCIPAL,"harley");

Context initial = new InitialContext(env);
Object objref = initial.lookup("java:comp/Test2");
//Object objref = initial.lookup("bean");
Test2Home home =
(Test2Home)PortableRemoteObject.narrow(objref,
Test2Home.class);
Test2 bean = home.create();
The bean is published as Test2, same as the remote interface, and the home
is
Test2Home.
It only compiles if i put the Client and the bean files in the same
directory
in the class path, but when i do that and run the file i don't get any thing
pack when calling a method on the bean.
The folder d:\orion\test2 hold the bean and within that is the client
directory. The bean meta inf has application-client.xml with reference to
the
remote and home interfaces of the bean. What else do i have to do to get
the
client to work with the bean probally and calling methods??

SV: Doubts on finder methods & orion-ejb-ar.xml
When you use the finde method you have to think the same way as when youre using a PreparedStatement. a value of ' name = = ' will be expanded to the following when a string is set into the prepared statement: ' name = 'string' ' so query="name like '%value'" is not likely to work if its a parameter, BUT if its a static value it works :) There is a couple of matters you have to take into consern depending on what database that is in the bottom of the system. 1) never set the dynamic value as the first in a comparance ie. "$1 = $name" you should allways set the field name first ie. "$name = $1" because of the database optimizer. 2) when using like keyword the best way to use it is to inform the users that % is the wildchar and then you will soon see some extremely cool usage of your finder methods :) ive seen search criterias like this before: "Fa%li%ca%" :) to use this in your finder use: query="$name like $1".' 3) remember its the field mapping inside your bean that is used to search against first in your appserver, so you should use the cmp field name not the percistence name in your finder query. So your fantasia example () should be written: But still my preference is to inform the users and do :) This is because if a user wants to type in a name without wildchars the database woill optimize the like the same way as if you did = in the select and the user will have better controll over the search... If you want the programmer to have control, you should make a session proxy bean that will add the % to the field, then the entity beans finder method can be used for more than that one spesific usage. Where I work we allways put a session proxy bean between the entity beans so we can chew the finder data before we do the search, so the entity layers finder method can be made more reusable throug the applications inside the appserver.

SV: IDE use with Orion
What auto and live deploy? As far as i have seen its just restart orion and it deploys. The IDE's i have used against Orion is: Vi, emacs, xemacs, forte4j, borland jbuilder, ibm visual age for java, Visual Cafe, pico, notepad, write. So far i havent found any that is better than the other when it comes to the integration against orion, but i can see potential for the orion crew to make a couple of modules for forte to get an "ide" that has ejb generation and so on matching Orion. This way orion application server would allso have a tool that does it good, like Sybase ASE has PowerJ, Weblogic has Visual Cafe and so on. Forte has an api to code plugins for the IDE to do vareous things. PS Orion crew, would like to see a module for forte4j that generates an CMP entity bean from a database table :) (its just so boring writing all those setters and getters, + synching the xml, hehe) and maby make a network deploy option for orion and make that as a module for forte aswell..

SV: Specifying finder-methods (full query)
The normal way of doing this is by implementing several finder methods, and
let a session bean do the entity querying..
For searching on names with wildchars just do:
query = "$name like $1"
this will actually serve as several finder methods (see examples under).
findByName("Bob");
This will return the same as the =.
findByName("Bo%");
This will return all matching records for Bo* and so on.
You can even do this:
findByName("Bo% %mi%th%");
Nifty :)..
For the other stuff you have to add more finder methods. Or make it a bean
managed persistance bean where you can toy around with the finder methods as
you like :)
Btw, important notice is: all findermethods implemented using like has to
return Collection not remote interface.
Have fun, hope this helps better :)

Hi Frank,
I apologise that my earlier reply was a bit off the mark. I hadn't read
the whole email carefully enough to realize exactly what it was that you
wanted to do.
So far as I know, the accepted solution to your problem is exactly the one
you tend to reject; using a stateless session bean to perform the direct
SQL queries for you. I agree that this sounds a little unsatisfactory.
After all, shouldn't the entity bean do everything to do with the entities?
A slightly more elegant solution may arrive when EJB 2.0 is fully
implemented. In EJB 2.0 the home interface of an EJB can also define
arbitrary (non-finder, non-create) methods. That may be a more logical
place to put a home-grown finder perhaps?

Well we have a project running tremendous amounts of EJBs, but what takes time is the Entitybean deployment. We get up to 15 minutes deployment time on a P600III on the full deployment. So what we did to speed up deployment was: Divide your application into specialized areas and make ejb-applications of them so you can redeploy one area at a time... Then you will only get that huge deploy everytime you do a full code refresh. :).. The other thing is to get a faster database :) Hope this helps .

I agree with JAAS as a good auth mechanism to use in orion. The only thing i can see as a good argument against it is they have to make a LOT of modules for different OSes. Still if there was a standard implementation of the user manager in orion so one have the choice of using the JAAS instead of principals.xml file, there should not be any downsides right orioncrew? It would be great to have JAAS, like for instance now, were running several projects where i work that needs to authenticate against a windows nt domain to get access to the application server, right now were looking on switching from orionserver to another brand just because of that it hasnt got any possabilities to authenticate against the oses rights.

Its actually important to us to get this information into the database server so we can see deadlocks and so on and if its our things that make them and so on.

SV: Orion 1.0 : Problem With Access DB (Ultradev Tutorial)...
Ok ill tell you something about ODBC: (I hate it :)
Ok nuff said about that, but i can tell my experiences accessing Microsoft
SQL Server 6.5 through jdbc:odbc. I had the exact same problems as you have,
but i found a working workaround for that:
1) When you get data from the result set don't use column names names, use
column numbers ie: (1) instead of ("Name") when fetching the data.
2) Never get column 2 before column 1 (and so on) or you will get some
strange error? don't ask me why I just found the workaround :). So in other
words if you are to use four columns get them out in local variables before
you start doing stuff, to make sure that the right sequence in the datafetch
is done against the result set.
Have a nice summer holiday all.

Hello !
As you suggested, I started looking at Dreamweaver Ultradev's generated
code:
Driver DriverrsReleaseSummaries =

Connection ConnrsReleaseSummaries =
DriverManager.getConnection("jdbc:odbc:scaalcoffee","","");
PreparedStatement StatementrsReleaseSummaries =

//StatementrsReleaseSummaries.setQueryTimeout(0);
ResultSet rsReleaseSummaries = StatementrsReleaseSummaries.executeQuery();
boolean rsReleaseSummaries_isEmpty = !rsReleaseSummaries.next();
boolean rsReleaseSummaries_hasData = !rsReleaseSummaries_isEmpty;
int rsReleaseSummaries_numRows = 0;
I commented out the setQueryTimeout() call (since this is apparently not
supported by the access ODBC driver) and this took care of the error I
mentioned in my first message. I am now having various problems with the
query itself.

What are the requirements for the JAX layer as far as the database is
concerned ? Do you need an "id" column in each table ? The second error is
something strange with using the prepared statement ??
Maybe you can make some sense of this. I would actually like to use some
other database like interbase but the product comes with this tutorial
database and I don't have the schema for it.

SV: Data integrity using JSP - EJB???? (Urgent)
Thanks for the answers. As far as using direct Entitybean access this is not anything i want to do, just because it can hold locs for longer than ai want them to do. Now I am implementing a model Christophe Hartwig agrees with me on (thanks for your mail) where i compare last timestamp on update to see if it match before update. This way i can serve loads of users and still contain the dataintegrity im after, and keep the locks to a minimum. When accessing Entity beans directly from a jsp you never know when to release the lock so i leave that to Stateless session beans where I give out Javabeans that can be played around with as i like in the jsp (i can forget about those guys whos browsers crash, those guys who run 4 sessions against the application and those guys who open the edit page and leaves for lunch :)). Now have a nice summer holidays everyone!

Did you use CMP entity beans to make your display beans from the session beans? This is how the pet store does it. If you do then the entity bean for that row will already be loaded so asking for it in your edit page would not be expensive except for all the calls to display the attributes.

Data integrity using JSP - EJB???? (Urgent)

BUG-Report: CMP and finder methods
Earlier on a colegue of mine posted a "note of frustration" on findAll(). I think i have found the reason. Reason: If you wrongly map the entity fields against the database, mismatches in the entity bean will make orion do strange things. Try map a sql char(1) to a java char :) When i remapped those to Strings all finder methods worked just fine. Symptome: All finder methods returning Collections fail until you reget the result as many times as there are rows in your search criteria. When you get the data all primary key fields will report null. Software used: - Orion1.0RC1 and RC2 - JDK1.3 Release - Sybse 11.5.1 with stored procedure upgrade for 12.0 so JDBC works properly - JConnect 5.2 and 4.2 Bug: Orion don't catch datatype mapping errors like char -> char(1) that should be String -> char(1), and the result is hassardous and very hard to find bugs. Thanks for a great product so far, now im just waiting for network deployment possability (hint hint) :) Med vennlig hilsen Klaus Myrseth Senior system consultant Exense ASA
Problems with JNDI context
We have some strange results when trying to sew our application together. Calling our EJBs from JSP pages worked fine for the EJB dev team, but when merging the different modules together to make one application after initial development of base modules didnt work to fine. We merged a Webapplication and an ejb application to one, and synchronized the configuration. But now it seems when browsing the JNDI context within JSP there is no beans deployed, but when using a java client we get access to the beans, and can browse the JNDI context Anyone have any ideas?? /Klaus
[TagLib] I have made a taglib that have some tags making things a whole lot easier for me but....
I use some jsp tags in the processed output, and is there any way i can process this after the taglib has walked through it an example of a page written by my library: Some page things in here <%= somevar %> My page wil generate amongst other things the errorpage tag <%@ page errorPage="/somwhere/errorpage.jsp" %>. Is it possible to make the jsp processor to extract my oputput from the taglib??? Med vennlig hilsen Klaus Myrseth System Konsulent - Info-expert AS Telenor Mobil AS - Planavdelingen
SV: jsp generating wml
This is a normal error to do in XML generation. The has to be the very first thing shown to the browser reading the file. The spec says no whitespaces are alowed before this very tag... So in your case you just have to remove some whitespaces in front of your tag. See under: <%@ page contentType ="text/vnd.wap.wml" session="true" %> If you do it like this i would belive youre going off with your first vml page :) You allso have to add you text inside the card inside a paragraph aswell: hi all If you use jsp pages to show all your cards like i do you dont have to configure the mime types at allThats what the content type is all about. PS. Wml browsers in phones dont handle cookies do add url tracking and dissable cookie tracking if you want sessions to work in all browsers. (to be sure to make this work post or get a variable called j_session? (dont remember) with the session id.. Good luckIts easy as soon as you get track of those stupid strange restrictions thats not to well documented :) Klaus Myrseth -Opprinnelig melding- Fra: Fiorini Simone [ mailto:[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> ] Sendt: 14. februar 2000 15:23 Til: [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> Kopi: Klaus Myrseth Emne: jsp generating wml Hi all Orion users, I have a jsp but I cannot generate a simple wml page: <%@ page contentType ="text/vnd.wap.wml" session="true" %> http://www.wapforum.org/DTD/wml_1.1.xml <http://www.wapforum.org/DTD/wml_1.1.xml> "> hi all I've also added the new mime types in the orion/config/mime.types file: text/vnd.wap.wmlwml application/vnd.wap.wmlcwmlc text/vnd.wap.wmlscript wmls application/vnd.wap.wmlscriptc wmlsc image/vnd.wap.wbmp wbmp Any help appreciated; also have you got any example of some simple Jsp which succesfully generates a wml page?

RE: Orion vs Apache, A Study of Features
> Designer thing.. Hey someone has to take those guys under their hat :) (didn't mean to make it that hard, was trying to make a joke aswell, but heh when i read it myself i sound angry rofl) Btw sorry for being so hard. But my first thought when reading your posting forced me to press the reply button with a provoked mouse click :) Its good to hear you are not serious about the first mail completely, since it all really has to do with budgets and customer preferences. (ps it's late here to :) And thanks for the 1.3 release candidate 1 tip, was waiting for it :) Klaus
RE: Orion vs Apache, A Study of Features
> A lot of these are obsolete technologies that Orion has better ways of > implementing. > Orion does that JServ/Tomcat can't do. What you are trying to do here, is to compare a Volvo with a Porche, and that is plain unfair. Apache and Tomcat is made for one thing, to be a webserver (It don't even come close to supporting the J2EE standard). Orion is something else, its a server that complies to the J2EE technology, and that technology is FAR more than a webserver. If you want to compare servers, you will have to take BEA WebLogic, Sybase EAS 3.5, with J2EE Service upgrade and so on. Orion is a good technology, dont missunderstand me, but get objective and compare it to someone its own size if you catch my drift :) > I also think Orion is better than say WebLogic because it is > so much easier to administer. Ofcourse its easier to admin, I would guess that the J2EE part of the server is just as easy to admin, have you seen all that stuff the WebLogic server supports, its the admins nightmare, and thank good its not my job, but its two servers of the same class. So if you compare them use some real arguments like, performance, price, uptime and so on. I think Orion is the best bet for a small to medium company who is looking for a total sollution to get on the web. WebLogic is a killer server whitch large organizations go for, because of its known and has been tested in HIGH trafic areas like Amazon.com and so on. Don't missunderstand me, i use Orion all the time at my customers, AND for development at my machine (size is everything hehe). If you are coming to a company with several different technologies in use for development, like visual basic, c++, powerbuilder, java, cobol and so on. I would actualy look at Sybase or BEA. But for a pure java sollution i think i would go for Orion, because its got good performance and is stable enough to impress any admin department running Microsoft :).. > we all know how dumb designers are Im a developerBut i would like to see your arguments for why designers are dumb? I know loads of them and they are highly inteligent (most of em anyways :) but ofcourse theyre experts at different areas than I (and thank good, then I don't have to do those things). I think you should do some more thinking before posting a letter like this. I still think Apache for instance is a killer for some firms. Depending on what theyre hosting there (its free you know, eaven for commercial hosting). And last time i checked Orion was still a Beta :) As a closing thing after so much negative speaking I want to say to the Orion crew: Good work, hope you will be ready for releasing your product with config panels and get a widely used product pretty fast. I like the product so far, I allready deployed one sollution on it, and the customer is happy (migrating from IIS). This product has huge potential, amongst other things because of the speed of the server, and since i just love java server implementations :), their SOO portable between platforms :)... Klaus Myrseth Orion is our firms prefered platform for Linux and WAP deployments btw :)
I have come to a strange problem with JSP - WAP dev...Keep alive, how do i switch it off???
I have some strange problems with the orionserver against wap phonesAs all prolly know, they dont support text/html mime type. My problem is that keep alive is sent in text/html, how do i switch this off It would be great having the option to switch this off in the web application. Do anyone know when the WAP addon for orionserver is done? Klaus MyrsethSystem KonsulentPostboks 70 Bogerud0621 OsloTlf: +47 22 62 70 10Fax: +47 22 62 70 10Mob: +47 95 23 75 37
RE: Orion on Linux
Luckily for you this is a typical error for linux when the Kaffe java is still installed...Just remove the kaffe java package from your linux installation or make the jdk bin directory show up before the other installation in your path. So your problem is that the kaffe 1.1.6 or something is trying to invoke orion instead of the jdk1.2.2. Hope this helps :) Happy new millenium guys.
