[JBoss-user] new Pet Store, new patch?
Apparently, the new Pet Store 1.1.2 doesn't use the 'problematic' J2eeSecurityAdapter. This got me to thinking that a new patch would not involve changes to the code or a recompile. In this direction, I have been plodding along hoping to get the new store up and running with JBoss 2.2.1/Tomcat on Windows ME. Being that I am new to all of this, a few things have slowed me down. I am hoping that someone can rescue me - now that I am knee deep. ;-) My questions are: In the web.xml file for pet store, what value should I use to reference the JBoss 2.2.1 server? The previous patch used "JBoss 2.1 Pre (www.jboss.org)" inside of . My only guess has been to replace the "2.1 Pre" with a "2.2.1" but this has not worked. The petstore.ear file seems to deploy fine (but I never scrutinized all of those messages yet). Pointing my browser at http://localhost:8082 shows me a list of MBeans, but I see a pet store at http://localhost:8080. By running "netstat -a", I even know that nothing is listening on that port. How does Tomcat port get configured? Any suggestions? With respect to cloudscape, the patch said to simply start it. The only way that I been able to do this is through Sun's J2EE server (i.e. "cloudscape -start"). How should I start cloudscape when using it with JBoss? Anyways, thanks in advance for any help that I might get. Cheers, Mike Donnelly

The WebService MBean is small HTTP server used for serving classes to remote
clients. The deployer wants to tell this service about the classes that it
is deploying.
Problem: it hurts when I comment out the WebService MBean.
Solution: don't comment out the WebService MBean.

The session bean would check, if the conference is in process by accessing above ConferenceBean, (then check some other stuff accessing some other beans ...) and THEN: write the contribution into a table without using an entity bean in order to circumvent the primary key issue, which started this discussion.

RE: [JBoss-user] Anyone know how to federate across multiple jnp ...
I believe that I am close, but I still have no cigar. Having read most of
the jnp code, I realize that JNP has implemented LinkRef and not Reference
as I first thought. In looking through org.jnp.client.Mail, I see that
LinkRef is supportted and that the use of it is to bind a LinkRef object
with an embedded URL. This URL may start with jnp://somemachine:someport.
So I run an experiment with 2 separate instances of JBoss running on the
same machine and I have Naming enabled on two different ports (1099, 1098).
I basically do a bind of:
env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "syan.zantaz.com:1099");
env.put(Context.URL_PKG_PREFIXES, "org.jnp.interfaces");
InitialContext ic = new InitialContext(env);
... create a couple of intermediate levels of name foo ...
... create a NamingContext nc pointing to foo ...
nc.bind("linksomewhere", new
LinkRef(jnp://syan.zantaz.com:1098/foo1)); // this already exists
... later in the code I do ...
Context ctx = ic.lookup("foo/linksomewhere");
At this point, I am getting the following exception. Am I using this
incorrectly?
javax.naming.NameNotFoundException: foo1 not bound

sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteC
all.java:245)

at com.zantaz.base.temp.Test6.main(Test6.java:21)
In walking through the code, it looks like env for the InitialContext is
reapplied for LinkRef. This seems incorrect to me, but I don't claim to
understand everything.

[JBoss-user] DataSource problems solved.
Thanks Guy.
Any chance we could have something like this added to the faq or the how
twos?
How to get a DataSource from a pool via JNDI.
1) get your pool installed (see existing docs)
2) Hard code the name of the pool.
this is the quick and dirty way.
in ejb-jar.xml you need something like
SequenceBean
demo.ejb.SequenceHome
demo.ejb.Sequence
demo.ejb.SequenceBean
Stateless
Container
the db for key
sequences
java:/SQLServerPool
javax.sql.DataSource
Container
the important part is res-ref-name, where SQLServerPool is the name of your
pool. In jboss.jcml your pool mbean starts looks like.
the important part (for our purpose here) is
name=SQLServerPool"
your code should look something like
InitialContext context = new InitialContext();
DataSource ds = (DataSource)context.lookup("java:/SQLServerPool");
test.
3) Move up a level of indirection with jboss.xml
jboss.xml need to be beside ejb-jar.xml in meta-inf
for a new project all it needs is
java:/SQLServerPool
jdbc/sequence
modify ejb-jar.xml
SequenceBean
demo.ejb.SequenceHome
demo.ejb.Sequence
demo.ejb.SequenceBean
Stateless
Container
the db for key
sequences
jdbc/sequence
javax.sql.DataSource
Container
modify your code, (SequenceBean in this example)
InitialContext context = new InitialContext();
DataSource ds =
(DataSource)context.lookup("java:comp/env/jdbc/sequence");
notice that the name used in code "java:comp/env/jdbc/sequence" maps to the
name in the res-ref-name in
ejb-jar.xml and res-name in jboss.xml. the res-name-jndi-name maps to the
name of the pool in jboss.jcml
test.
this worked for me on jBoss 2.2.1

RE: [JBoss-user] Re: JAWS: Is this a bug, or is there another rational
I think streaming into postgres only works with the "Fasttrack" API. Have a look at the postgres JDBC doc - there are a few examples how to do it and I played around with it a while ago and it worked well. I think you have to downcast the statment and then there is a large object API. As far as I remember, the methods on statement dealing with streams are not implemented - have a look at the source.

Re: [JBoss-user] Transaction blocks forever, LOCKING-WAITING
Hi all,
since my original posting I upgraded from 2.1 BETA binary
distribution to the 2.2.1 binary distribution of JBoss and
testet again:
The problem essentially remains, the sequence of accesses has
changed a little, I can now access several beans in the first
place, but after a short while I again get a block in the JNDI
lookup() method followed by a transaction timeout message but
with no exception raised. The entity bean remains associated
with the transaction for ever; the next access to it again
produces the millions of 'LOCKING-WAITING (TRANSACTION)'
messages and only a server shutdown helps.
Are we doing it wrong, is a JNDI lookup inside a transactional
business method forbidden? Any other suggestions?
Thnaks in advance
my best regards
Georg

[JBoss-user] JAWS: Is this a bug, or is there another rational explanation.
Hello. I have an entity bean. Let's call it, Joemama. It uses CMP. I'm trying to create an instance of that entity bean, so I call a create method on its home interface. When JBoss attempts to insert a row into the database for this new bean instance, it calls PreparedStatement.setBinaryStream() for a column and the JDBC driver throws an exception saying that 'InputStream as parameter not supported'. I have a feeling JBoss might be trying to call setBinaryStream() on a column for which setBinaryStream wouldn't make sense. In fact, the table definition for storing the Joemama bean, created by JBoss using the PostGreSQL mapping is as follows: Table "joemama" Attribute | Type | Modifier ---+-+-- version | integer | catalog | text| modified | oid | type | oid | created | oid | id| integer | It's not clear to me that you'd want to call setBinaryStream() on any of those columns, but then again, I'm not sure about those oid columns. The actual stack trace from the server log looks like this: [Joemama] BaseItemBean: ejbCreate() [JAWS] InputStream as parameter not supported [JAWS] at org.postgresql.jdbc2.PreparedStatement.setBinaryStream(PreparedStatement.java:417) [JAWS] at org.opentools.minerva.jdbc.PreparedStatementInPool.setBinaryStream(PreparedStatementInPool.java:252) [JAWS] at org.jboss.ejb.plugins.jaws.jdbc.JDBCCommand.setParameter(JDBCCommand.java:326) [JAWS] at org.jboss.ejb.plugins.jaws.jdbc.JDBCCreateEntityCommand.setParameters(JDBCCreateEntityCommand.java:165) [JAWS] at org.jboss.ejb.plugins.jaws.jdbc.JDBCCommand.jdbcExecute(JDBCCommand.java:159) [JAWS] at org.jboss.ejb.plugins.jaws.jdbc.JDBCCreateEntityCommand.execute(JDBCCreateEntityCommand.java:135) [JAWS] at org.jboss.ejb.plugins.jaws.JAWSPersistenceManager.createEntity(JAWSPersistenceManager.java:122) [JAWS] at org.jboss.ejb.plugins.CMPPersistenceManager.createEntity(CMPPersistenceManager.java:207) [JAWS] at org.jboss.ejb.EntityContainer.createHome(EntityContainer.java:441) [JAWS] at java.lang.reflect.Method.invoke(Native Method) [JAWS] at org.jboss.ejb.EntityContainer$ContainerInterceptor.invokeHome(EntityContainer.java:639) [JAWS] at org.jboss.ejb.plugins.EntitySynchronizationInterceptor.invokeHome(EntitySynchronizationInterceptor.java:160) [JAWS] at org.jboss.ejb.plugins.EntityInstanceInterceptor.invokeHome(EntityInstanceInterceptor.java:87) (snipped to protect the innocent reader from what in reality is a very long call stack) At any rate, I'm not really sure why this is happening or what I can do about it. It looks like it might be a bug in JBoss's CMP code, or it may be the result of something screwy I've done. Any ideas? I've tried to run JBoss in jdb, but that didn't work for some reason. Hung when I asked it list threads. I may download Forte and check out that debugger. This is very strange, though, since I have another entity bean which is effectively identical to Joemama, same table structure, same CMP fields, and it works fine. The table in the database is identical, the code in the Bean class is identical, and I even copied the same deployment descriptor and only changed the name. Go figure. If anybody has any ideas, please let me know. I'll include the deployment descriptor for Joemama below.

Re: [JBoss-user] Oracle Sequences PK in Session bean
The currval column of a sequence in Oracle will always return the same value as
the last nextval in the current transaction. You should never have problems with
concurrent access by "someone else" unless you are not in a transaction. But I
have no idea how you'd achieve not being in a transaction in Oracle.
There is no need to retrieve the nextval in you bean before the insert. We used
the approach of retrieving currval after an insert for 10 years and have never
experienced a problem.

Re: [JBoss-user] Oracle Sequences PK in Session bean
This approach will not work reliably. Between your insert of nextval and
your select of currval, someone else may have inserted another row, such
that your currval will actuall retrieve the wrong currval. I suppose you
could address this with synchronized, but a better way (IMO) is to retrieve
the nextval into your code. You can then use it for the insert and also no
the value for any further use you may have, and not have to worry about
multi-user issues.
We always wrap the sequence with a getter function, and this has saved our
hides many times. For example, let's say you start by using the sequence
number as your primary key. Then someone comes along and decides that they
want the IDs to look like "CS1". You may have to change code in
several places if you just access the sequence directly, but if you wrap it
in a getter function, you don't have to change anything but that getter
function.

I'm not sure what you mean by the EJB needs to know the primark key to return it... All your entity beans need to have a primary key, but your home interface can have finder methods that don't need the primary key. If you have different people making contributions, then you are probably (my poor assumption) going to need a way to tell who made what? So you can search by the username field or something like that to get vack a COllection of all the entity beans that have that username. You can do this with ny field, of course, although I'm not exactly sure how it would work with a BLOB. > But I could also do it this way: > > I have an EJB which represents one collaborative session - let's call it a I'm not sure what a collaborative session is - one record or many?

Generally, a good EJB design will use a session bean to access entity beans. Your busines logic would go into the session bean, so methods that create new data, manipulate existing data and so on would go here. This presents a nice API to the rest of the code that you can change the implementation of. So the session bean might have a method like sendText(text, client) Now, the issue of the data and how its related. It seems like you are talking about having two entity beans. One to represent the person (or client?) making the contribution. This EB might have fields to identify that person. Next, you have an EB to represent the contribution. This EB might have a field to home the contribution, like a BLOB field. It would be easy if you hade only one contributiun type, but if you have multiple types (text, binary) you may want to look at multiple EBs for each type. So, your session bean would be handed the user id of the contributor and the contribution and told to make a new EB to represent the contribution. You would then find the EB for the contributor, get its remote inteface (using a finder from its home object) and give the remote interfce to the contribution EB to relate the two. EJB 1.1 does not handle these things very well if your using CMP, but thats being fixed in EJB 2.0. > That table could be created with an AUTOINCREMENT (or similar, depending > on the database) for the primary key and thus primary keys are generated > transparently by the database during the INSERT.

Probably, you might want to look at using BMP for this contribution bean. Under BMP, you write all the database code with JDBC. When the bean is created the create method you wrote is called. You could create the record and let your database init the autoincrement field, then read it back. Also, you would handle the relationship using the PK rather than a serialized remote interface. But I would not recomend that at all. I would recomend that you use a unique key genertor to create your key. If you don't you'll be heavily tied to whatever database you write this for. The java.rmi.server.UID class will generate a unique key for the machine your using, and you can add the IP address for global uniqueness. If your just starting pout with this, you may want to look at EJB 2.0. The spec is not final yet, but its close. EJB 2.0 CMP h

Re: [JBoss-user] Oracle Sequences PK in Session bean
(Note that this is Oracle specific - ie. non portable)
I'm not sure if this will help, since it is not a Sesion bean as you asked,
but...
This is the ejbCreate() method for an Entity Bean that I have come up with to
insert a new record into an Oracle Database Table where the primary key is
generated using a Sequence.
After inserting the record, I get the current sequence number and set the
Primary Key to it. I originally tried to do this step in the ejbPostCreate(),
but I needed to obtain the value for the Primary Key prior to returning from the
ejbCreate().
I hope that this helps

Re: [JBoss-user] Oracle Sequences PK in Session bean
I wrote a SequenceManager SSB, which takes plug-able (Sequence DAO objects) to access to underlying database. It could definitely use some improvements, like better value caching and such. I would be willing to share it, but I am not really sure where the appropriate place would be. Perhaps a contrib module? Though that seems a little overkill for one SSB. --jason On Mon, 7 May 2001, Sacha Labourey wrote: > Hello, > > Does someone already has developped a session bean for JBoss which sole purpose is >to get an Oracle Sequence value from an underlying Oracle database?

Re: [JBoss-user] Anyone know how to federate across multiple jnp...
Ok, I double checked (with the latest CVS JBoss), with the following:
from java.lang import *;
from java.util import *;
from javax.naming import *;
env = Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "jnp://reason.boldfish.com:1099");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
print env;
ctx = InitialContext(env);
print ctx
print ctx.lookup("java:/Mail");
ctx.close();
Using a classpath with the following:
jython.jar
activation.jar
mail.jar
jndi.jar
jboss-client.jar
jbosssx-client.jar
jbossmq-client.jar

from a war file if it wasn't extracted during deployment. Some application
servers don't extract ears, wars, & jars during deployment unless you
instruct it to do so. This probably doesn't apply to your situation because
you're serving files from a directory.

I was going to suggest using something like the IO taglib from
Apache-Jakarta http://jakarta.apache.org/taglibs/index.html. Unfortunately
the IO taglib link on this page is broken. I don't know if it contains a tag
specifically for this purpose but it seems like the best candidate. Perhaps
you should write a tag library to list files. I suspect taglibs already
exist that do this. I just didn't know of any other taglib lists off-hand.

Don't get a JDBC connection like that. Set up a DataSource and refer to it
using the java:comp/env JNDI context. See the many examples of this all
over the place.

Re: [JBoss-user] Callbacks with MessageDrivenBeans
Not tested on JbossMQ, however, it should not. You have to use filter to make sure of that. To make an instance-specific filter, I guess the worst case is you need a IDgenerator (some discussions in this mailing before, or, go to theserverside.com ), esp. if you have multiple instances of jboss and jbossMQs. However, you may just use the string form of the ejb's instance ID (not sure how unique it can last, should be longer thatn 30mins?)

Re: [JBoss-user] Anyone know how to federate across multiple jnp ...
Scott, thanks very much for the explanation. The reason I am doing this is that for security purposes, we want to move as much as possible off the standard ports (we'll have a firewall.) Is there anywhere an all-inclusive list of the ports that JBoss uses (out of the box - er, zip - I realize JBoss allows additional functionality to be plugged in), and how to change them? I know clients contact the naming service on 1099. Does this work like ftp, where the server will immediately spin off another port to carry on the conversation so that 1099 stays free for the next client? After lookup is complete and client instantiates the ejb remote interface, is there any way to know what port on the server side will be used for the ejb to talk to the client? Must we use a custom socket factory for that? > This jboss.jcml entry: > > along with this jnp.properties file: > ### JNP server configuration > jnp.port=1299 > jnp.rmiPort=0 > > results in the naming service starting on port 1299: ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

You get an exhausted result set exception when you scroll past the end of your result set and continue to try and extract results. Make sure you are using something like while(rs.next()) so you don't overrun your result set. Note this is a different exception than you get if you try to do to many getString's from a single row.

Re: [JBoss-user] (no subject)
We addressed this problem by doing the following (not saying this is an
optimal solution, but it is a solution). We used this solution for a
different purpose - to achieve portability between Unix and NT platforms,
but it should work for you as well.
1) In a well-known place in your document tree (i.e., somewhere where
Tomcat can see it), create a constants file. We put it in
/common/html/globaldef.jsp. In this file, have entries like this:
static final String aWarDir = "C:/JBoss/temp/deploy/MyWAR.war";
2) In your JSP page, now include this file and use the string. Yes, you
are still using a hard-coded directory, but you only have it in one place so
it is easy to manage.
3) Because your web1005 directory changes each time you deploy, you'll have
to search for it relative to the known directory.

But my apprehensions using XML have been - XML parsing is still non-trivial and resource intensive, they increase the amount of stuff passed over the wire and finally I really need to justify to myself the usefulness of an RPC mechanism! Probably for B2B scenarios - YES. For integrating between disparate systems - YES. But to use it indiscriminately would be expensive. Most often the payload proves much smaller than the tags! EJBs based around an XML - RPC mechanism? Why? Where would you want to have that? Since the underlying data format is XML [i.e. Strings] we would need to go about creating objects and stuff from them and that is also expensive.

I read a little quite a while ago about this simple yet amazing technology, but I thought it was some kind of M$ thing and so got disinterested by it. Now that I've looked it from a bit closer, I think it really is a great thing ! Not only because it lets Java applications talk to all other platforms and languages, but also because of its capability to deploy web applications that behave as services (yeah, I know this is M$ goo, but the word say it best). Apparently there's so little interest in this technology from the EJB community that the ZOAP project seems to be dead, and that the Apache SOAP team seems to be marginally interested in developing EJB support (they *did* work on that, but in my own short experience it works on windows and not on linux !!!). Because of the very little overhead associated with this kind of invocation (AFAIK), I think it could even be the default method for J2EE clients accessing remote EJB's, but that's just an idea...

JBoss hangs, because the database setup in your jboss.jcml contains true change this to 'false' and JBoss should throw an exception or at least return null.

Re: [JBoss-user] problem with JNDI lookup...
I got this to work by copying my ejb's jar file to JBOSS_HOME\lib\ext
I'm not sure why this is needed since this file is already in the deploy
directory.
Also, Can someone point me to a good resource to explain what .war and .ear
files are supposed to contain and what threir purposes are?
Thanks,

RE: [JBoss-user] SOAP
Web services concept uses WSDL file to describe the service and SOAP as a transport protocol. That WSDL file is essentially your 'simple declarative file'. You then register your service with a public or private UDDI registry via the WSDL file and your services/methods/functions/calls are available to the world. My sense is ejb is the middle-tier machine and this web services technology will provide b2b or xml portal or (how many buzz words can we throw in here?). Yes, parsing overhead and wrapper et al is not trivial so you don't use SOAP as a generic internal interface, but I believe it will become a key platform neutral external interface. (BTW, I've seen references of 40-400 rough-rough-rough calls per second w/ SOAP). Do we need to beat on this in jBoss now? No. As others have noted it's just another external API into our box. ALSO ALSO ALSO (wow), SOAP is keyed to XML Data Schema and that's much more powerful than DTD, so the parsers are having trouble. Check out comparisons of SOAP parsers. For trivial stuff they play nice together. But for arbitrarily complex input/output forget it. I'm running my mouth/fingers, but this is an interesting area for me.

[JBoss-user] Strange behavior at start up...
Hi all, I'm a newbie to jBoss... i'm testing it for a project. I observed a strange behavior of jBoss at startup... i added a data source at jboss.jcml using a postgresSQL jdbc connection, but have forgotten to add the jdbc driver for postgresql in the drivers section. At start up, jBoss prints : [PostgreDS] Starting[PostgreDS] XA Connection pool PostgreDS bound to java:/PostgreDS and then it hangs there indifinitely. My questions : 1)-How is it possible that jBoss can create connections pool using postgresql, while the acurate driver is not even loaded? 2)-Why jBoss hangs there? Why doesn't it just throw an exception, something like "Driver not found"? and last... 3)-How can i disable default data sources shipped with jBoss, like InstantDB and HyperSonic? I put in comment the tag describing them at jboss.jcml, but they refuse to go away ... jBoss always attempt to bind them to java:/InstantDB and java:/DefaultDS Thanks for your help. --hermann

You have two problems:
1. You need to have a jboss.jndi in your classpath somewhere, for jndi
to understand that it should be using jnp, eg:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=localhost:1099
java.naming.factory.url.pkgs=org.jboss.naming
2. You are using the wrong name for a topic connection factory. Do this
instead for example:
public class Main {
public static void main(String arg[]) {
try {
// Get access to JNDI
Context context = new InitialContext();
// Lookup the managed connection factory for a topic
TopicConnectionFactory topicFactory =
(TopicConnectionFactory)context.lookup("TopicConnectionFactory");
//This is the real JNDI name

RE: [JBoss-user] TRANSACTION ROLLBACK EXCEPTION:Could not activate
I assume, that the session object was destroyed while the exception occur. If the container can't get the session object he assume the session was passivated (and serialised). If You enclose the method, which may throw a rollback exception, in a try-catch block and throw a remote exception to the client, the client should be able to connect the session bean again.

String absPath = config.getServletContext().getRealPath("/");

[JBoss-user] Need help to run a message bean; LookUp-call to get TopicConnectionFactory fails.....
Hi! I really need assistance from You; can You help me understand how to set
up connection factory in JBoss-2.2.1?:
I'm trying to get a simple Message Bean to work on JBoss-2.2.1. JDK1.3 is
used.
My client fails when it tries to lookup the connection factory; What must I
do to get the client to recieve a connection factory? Must the XML
config-files be updated with connection factory parameters?
-
The message bean is like the simple "HelloWorld MDB" in the JBoss
documentation. The bean is OK deployed with this ejb-jar.xml:
http://java.sun.com/dtd/ejb-jar_2_0.dtd'>
MDB
test.bean.MDB
Container
javax.jms.Topic
NonDurable
MDB
onMessage
javax.jms.Message
Supports
-
The Message Bean is deployed with this jboss.xml:
MDB
Standard Message Driven
Bean
topic/testTopic
-
I have this client that tries to send stuff to the message bean:
import javax.naming.*;
import javax.jms.*;
public class Main {
public static void main(String arg[]) {
try {
// Get access to JNDI
Context context = new InitialContext();
// Lookup the managed connection factory for a topic
TopicConnectionFactory topicFactory =
(TopicConnectionFactory)context.lookup("TOPIC_FACTORY"); //HOW DO I
REGISTER THIS CONNECTION FACTORY?
//Create a connection to the JMS provider
TopicConnection topicConnection =
topicFactory.createTopicConnection();
// Creat a topic session
TopicSession session = topicConnection.createTopicSession(false,
Session.AUTO_ACKNOWLEDGE);
// Lookup the destination you want to publish to
Topic topic = (Topic)context.lookup("topic/testTopic");
System.out.println("Topic set...");
// Create a publisher
TopicPublisher pub = session.createPublisher(topic);
// Create a message
TextMessage message = session.createTextMessage();
message.setText("Hello World!");
// Publish the message
pub.publish(topic, message);
// Close the stuff
session.close();
topicConnection.close();
}
catch (Exception e) {
e.printStackTrace();
}
}
}
-
Sets this CLASSPATH before running the client:
set
CLASSPATH=D:\JBoss-2.2.1\client\ejb.jar;D:\JBoss-2.2.1\client\ejb.jar;D:\JBo
ss-2.2.1\client\jnp-client.jar;D:\JBoss-2.2.1\client\jta-spec1_0_1.jar;D:\JB
oss-2.2.1\client\jbossmq-client.jar;.;D:\JBoss-2.2.1\lib\ext\jms.jar;
When the Main-client is run this ERROR appears:
javax.naming.NoInitialContextException: Need to specify class name in
environment or system property
, or as an applet parameter, or in an application resource file:
java.naming.factory.initial
at

[JBoss-user] ClassCastException on forName ...
Hi all,
i'm trying to acces a SQL Server database through a stateless session bean called DCS.
When i execute the following code, i get a ClassCastException. And i can't figure out
why !!
the driver is in my path and classpath, the name is checked and ok, ...
code:
try
{
String myDriver = "com.inet.tds.TdsDriver";
String url = "jdbc:inetdae7://onuris.groept.be?database=JFK_CarTracker";
String loginname = "name";
String password = "password";
Class.forName(myDriver);
Connection con = DriverManager.getConnection(url,loginname,password);
...
Does anyone has an idea of what i am missing ??? Any help would be really appreciated !

That probably means that java.sql can't do it. Even if it could, that

Actually, the original question came up in this context:
I am developing a collaborative application which stores the contributions
of participants in a database. These contributions could be text messages
or other objects, stored as blobs. None of the individual elements will be
useful as a primary key and thus I thought, why not let the database create
a unique key. My original question arose from the fact that an EJB needs to
know the primary key in order to return it and my assumption that I have to
call create(...) on an EJB in order to insert new data.
But I could also do it this way:
I have an EJB which represents one collaborative session - let's call it a
Conference. It represents a record in a table called conferenceTable. In
creation of this conference, all the issues discussed concerning uniqueness
of keys are relevant. But because I create that only once I may even
trouble the creator to enter a unique conference id. (Don't we all know it:
"Your userid isnt unique. Try again. Suggestion: 'mk$rtio237k'. :-)". Then,
during the session, participants will add a lot of information and that's
where I want to minimize the effort for creating unique keys.
I can add methods to my Conference bean like Conference.sendText( text,
client ) or Conference.sendOtherStuff( blob, client ) and then within these
methods do INSERTs into another table which hold the contributions of
participants, somehow like this:
Conference.sendText( text, client ){
...
t_stamp = System.currentTimeMillis();
INSERT INTO contributions( confID, text, client, timestamp ) VALUES
conferenceID, text, client, t_stamp );
...
}
That means my ConferenceBean - which represents a record from the
conferenceTable - INSERTs data into another table.
That table could be created with an AUTOINCREMENT (or similar, depending on
the database) for the primary key and thus primary keys are generated
transparently by the database during the INSERT. But I don't need to know
it, because the INSERT is not performed in an ejbCreate() method and
doesn't need to be returned.
(In reality I will probably write a second EJB, which participants can use
but which does not allow access to all fields of the Conference record.)
Does that sound reasonable or am I in for trouble somewhere else?

[JBoss-user] (no subject)
Hello:
I am having a problem running a JSP and I was hoping for some advice. I am
running embedded Tomcat.
I have the following setup:
index.jsp
directory/fileA.txt
directory/fileB.txt
The job of index.jsp is to list the files in "directory." For this, I was
trying to use something like this:
File directory = new File("directory")
String[] fileList = directory.list();
Of course, because JSP needs to be compiled, and it is done so in another
directory, when this code is run index.jsp does not find the "directory"
directory.
If I change the file path to an absolute path
File directory = new
File("C:/JBoss/temp/deploy/MyWAR.war/web1005/directory");
it works fine. I am using this path because it is the only one I can find in
the JBoss directory and in the Tomcat directory. Of course, this is not a
standard path and, to make things worse, every time I deploy the WAR file
the "web1005" token changes to something else.
So the question is, is there a way to list files in a directory by using a
path relative to the location of a JSP page?
Thanks in advance,
Felix Munoz

Re: [JBoss-user] EJB question
Or, if you want a sollution thats free and lots easier, look at your java SDK docs at java.rmi.server.UID class. One of the major critisims of EJB as it currently exists is that it can't take advantage of a databases "serial" or "autoincrement" field. Of course, these all vary from database to database anyhow, and EJB is not even tied to a relational database. So using a primary key generator is a necessity if you can't create your PK from your data (maybe by combining other fields). Good luck!
