Hmmm, apparently Serialization and I/O libs have received a lot of attention. Guess that would have a positive impact. Especially the way things are serialized. We looked at this and found that there is lots of room for improvement... (pre 1.4). *sigh* Sometimes it's just all too visible that different groups within Javasoft are working on parts of the core SDK. It's sometimes so inconsistent and the quality varies greatly. ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

[JBoss-user] Strange Session Bean behaviour in 2.4.1
Hmmm, I am deploying the same application on 2.4.0 and 2.4.1. Now, I've got a logging statement in the create method of the session bean and to my surprise I noticed that in 2.4.0 the statement only appeared once when I connected with the client, in 2.4.1 however they appear numerous times which is kind of strange and slowing things down unnecessarily.

In fact, it was Marc that raised the controversy with EJB and persistence. I don't think that a different app server will solve that problem. However, I really don't know why you need such high numbers of concurrent connections? Also, if you are using EJB and are worried about the persistence part, I recommend you give PostgreSQL a try since it's locking is much more fine grained and thus better suited for systems that make a lot of small requests. I've noticed a big performance increase --which kind of surprised me. I recommend you compile the Postgres JDBC driver yourself and give that a go.

If you are try to log from within any of your Beans you can do the
following:
==
import org.jboss.logging.Logger;
.
.
.
.
.
Logger.warning ("Problem locating UDFs for removal:" + e);

I think you need to add jboss.jar to your classpath.

I am not sure what the limits of your mysql/jdbc-driver combo are wrt concurrent connections. There could be OS limitations as well. You can make a direct connection to the database by getting the DataSource via JNDI and then use it just like with BMP. There is an example of that in the JBoss docs IIRC. You could drop the entity bean stuff entirely and just access the DB from session beans. In some cases this is quite desirable, as I found out. > I understand since Blocking is set to true that it waits for a new > connection.

In the first place I'd check my OS limitations for concurrent network connections and then the database and make sure that the driver doesn't bomb out. It's quite unlikely that it's XADataSourceLoader. Try setting the max value to 200 and see whether the problem persists.

[JBoss-user] JAAS and JSP
I need help in security matters. I've read the JAAS Howto and got the (thin) client to sucessfully authenticate itself etc... (using DatabaseServerLoginModule). I'd like to try out the same with JSP pages (unfortunately no example but cannot be that different since it is in essence a servlet itself) but appear to have some problems. First, the web server doesn't give me the popup box for authentication (as advertised in the Howto), so I decided to do this via a login page. Not a big problem since this is much closer to a real-life scenario anyway (we'll need this later on). The first problem is that the webcontainer does't seem to know about the security-authentication mechanism since it says: [Default] java.io.IOException: Properties file users.properties not found [Default] at org.jboss.security.auth.spi.UsersRolesLoginModule.loadProperties(UsersRolesLoginModule.java:200) I'd expect any errors to come from the DatabaseServerLoginModule. What didn't I do, and where should I put my client's auth.conf? WEB deployment descriptors attch'd.

JAWS can create custom finders for you. However, since these finders sitting on the home interface want to activate a bean, they may not always what you want. I recommend you use a session bean for the workflow part. This way you can comfortably handle relationships over multiple beans with the benefit of a transaction rollback should something go wrong. Other possiblities include "mixing" BMP and CMP. Some beans I've deployed as CMP but implemented some custom methods which look up the datasource and do some custom SQL --just like in the ol' days :) Works a treat. -- Nicolai P Gubahttp://www.gnu.org http://www.frontwire.com mailto:[EMAIL PROTECTED] mailto:[EMAIL PROTECTED] GSM: +44 (0)7909 960 751 DDI: +44 (0)20 7368 9708 ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

[JBoss-user] Writing custom SQL in CMP Bean
Is it possible to write some custom SQL for a CMP Bean?
Something along the lines of:
public void setCompanyStakeholders (ArrayList a,
long firstIdBlockNum)
throws RemoteException
{
final String query = "INSERT INTO Stakeholder (id, companyId,
firstName, lastName, email, dateCreated, lastModified, createdBy,
mimeTypePreference, modifiedBy, source, neverContact, validEmail,
optIntype, optInVerification) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?,
?, ?, ?, ?)";
Connection connection = null;
PreparedStatement prepStmt = null;
try {
connection = this.dataSource.getConnection();
prepStmt = connection.prepareStatement (query);
long id= firstIdBlockNum;
int size = a.size();
for (int i = 0; i < size; i++) {
StakeholderData data = (StakeholderData) a.get (i);
Timestamp timestamp = JDBCHelper.getTimestamp();
id = id++;
prepStmt.setLong (1, id);
prepStmt.setLong (2, data.companyId);
prepStmt.setString(3, data.firstName);
prepStmt.setString(4, data.lastName);
prepStmt.setString(5, data.email);
prepStmt.setTimestamp (6, timestamp);
prepStmt.setTimestamp (7, timestamp);
prepStmt.setString(8, data.createdBy);
prepStmt.setString(9, data.mimeTypePreference);
prepStmt.setString(10, data.modifiedBy);

prepStmt.setBoolean (13, data.validEmail);
prepStmt.setInt (14, data.optInType);
prepStmt.setInt (15, data.optInVerification);
prepStmt.executeUpdate();
prepStmt.clearParameters();
Log.debug (this, "setCompanyStakeholders: " + data.email);
}
etc ???
I don't think it would be possible since I tried deploying this and got
the following back:

[JBoss-user] java.lang.ClassCastException: $Proxy339
A small problem with BMP. I need some methods to return large amounts
of data. I noticed that initializing a new entity bean for every single
data item (there are more than 50,000 rows), is very time consuming and
not really required in this scenario. So I switched to BMP and defined
the following finder method:
public Collection ejbFindByCompanyId (long companyId)
throws FinderException, RemoteException
{
Connection connection = null;
PreparedStatement prepStmt = null;
ResultSet result = null;
ArrayList list = new ArrayList();
try {
connection = this.dataSource.getConnection();
prepStmt = connection.prepareStatement (companyIdQuery);
prepStmt.setLong (1, companyId);
result = prepStmt.executeQuery();
while (result.next()){
loadStakeholderData (result);
if (this.id > 0) {
StakeholderData data = new StakeholderData();
data.id = this.id;
data.companyId = this.companyId;
data.firstName = this.firstName;
data.lastName= this.lastName;
data.email = this.email;
data.createdBy = this.createdBy;
data.dateCreated = this.dateCreated;
data.mimeTypePreference = this.mimeTypePreference;
data.modifiedBy = this.modifiedBy;
data.neverContact= this.neverContact;
data.optInType = this.optInType;
data.optInVerification = this.optInVerification;
data.source = this.source;
data.validEmail = this.validEmail;
data.lastModified= this.lastModified;
list.add (data);
System.out.println ("ejbFindByCompanyId: Adding " +
data.email);
}
else {
System.out.println ("Invalid Stakehodler.id" +
this.id);
}
}
return list;
}
catch (SQLException e){
throw new EJBException (e.getMessage());
}
finally {
JDBCHelper.close (connection, prepStmt, result);
}
}
Note that StakeholderData is a class implementing Serializable. Now,
when I call this finder from a session bean like:
public ArrayList getCompanyStakeholders (StakeholderData data)
throws RemoteException, FinderException, EntityDataException
{
this.verifyLongId ("StakeholderData", data.companyId);
try {
Collection c = this.stakeholderHome.findByCompanyId
(data.companyId);
ArrayList list = new ArrayList (c);
int size = list.size();
System.out.println ("list size = " + size);
for (int i = 0; i < size; i++ ){
StakeholderData o = (StakeholderData)list.get(i);
System.out.println (o.email);
}
return list;
}
catch (FinderException e){
throw new EJBException (e.getMessage());
}
}
I get the following:
[ClientController] list size = 20

Oh dear! Looks like either your ant version is not the expected one or
that the build.xml file needs looking into. Looking at the error
message, why does it think that the client file is called ${client}?
Shouldn't this value have been substituted?

[JBoss-user] [HOWTO] Autoincrementing Primary Key with CMP
e PostgreSQL uses for sequences [a much better way of doing it than mySQL IMO]). Not all databases support such feature. However, I believe that it should be possible to provide a facility that returns the value for the row_id even if the database has no facilities as such. The backend implementation would then simply provide the number from the sequence generator utility. Whether this makes sense for Jboss or not is something I haven't thought about much. It would definitively be a bonus for developers. However, what would definitively be a winner is to provide a sequence generator implementation with JBoss, similar to Orionserver.

public static void close( Connection c, PreparedStatement s, ResultSet r )
{
try {
if( c != null ){
c.close();
}
if( s != null ){
s.close();
}
if( r != null ){

}

Now what? It appears as if the PreparedStatements are being cached
(not necessarily a bad idea) but do these resources get reclaimed by JBoss?
H Could not find much info about this.

Not sure whether I am able to accurately pinpoint why the system thinks it is out of memory... :( npg@raphael:~$ free total used free sharedbuffers cached Mem:255332 253244 2088 0 0 153308 -/+ buffers/cache: 99936 155396 Swap: 497972 0 497972 [User] TRANSACTION ROLLBACK EXCEPTION:unable to create new native thread; nested exception is: java.lang.OutOfMemoryError: unable to create new native thread [User] java.lang.OutOfMemoryError: unable to create new native thread [User] at java.lang.Thread.start(Native Method) [User] at sun.rmi.transport.DGCClient$EndpointEntry.(DGCClient.java:218) [User] at sun.rmi.transport.DGCClient$EndpointEntry.lookup(DGCClient.java:190) [User] at sun.rmi.transport.DGCClient.registerRefs(DGCClient.java:108) [User] at sun.rmi.transport.LiveRef.read(LiveRef.java:267) [User] at sun.rmi.server.UnicastRef2.readExternal(UnicastRef2.java:57) [User] at java.rmi.server.RemoteObject.readObject(RemoteObject.java:203) [User] at java.lang.reflect.Method.invoke(Native Method) [User] at java.io.ObjectInputStream.invokeObjectReader(ObjectInputStream.java:2213) [User] at java.io.ObjectInputStream.inputObject(ObjectInputStream.java:1410) [User] at java.io.ObjectInputStream.readObject(ObjectInputStream.java:386) [User] at java.io.ObjectInputStream.readObject(ObjectInputStream.java:236) [User] at org.jboss.ejb.plugins.jrmp.interfaces.GenericProxy.readExternal(GenericProxy.java:166) [User] at org.jboss.ejb.plugins.jrmp.interfaces.HomeProxy.readExternal(HomeProxy.java:265) [User] at java.io.ObjectInputStream.inputObject(ObjectInputStream.java:1212) [User] at java.io.ObjectInputStream.readObject(ObjectInputStream.java:386) [User] at java.io.ObjectInputStream.inputClassFields(ObjectInputStream.java:2262) [snip] -- Nicolai P Gubahttp://www.gnu.org http://www.frontwire.com mailto:[EMAIL PROTECTED] mailto:[EMAIL PROTECTED] GSM: +44 (0)7909 960 751 DDI: +44 (0)20 7368 9708 ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

Very sorry to hear that your employer's business went belly-up. Talking about JBossPool features Is it possible to add a new connection to the pool without having to restart the server? -- Nicolai P Gubahttp://www.gnu.org http://www.frontwire.com mailto:[EMAIL PROTECTED] mailto:[EMAIL PROTECTED] GSM: +44 (0)7909 960 751 DDI: +44 (0)20 7368 9708 ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user

You prolly have a line like: taglib PUBLIC "-//SunMicrosystms, Inc.//DTD JSP Tag Library GS> 1.1//EN" "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd"; Simply repace the URI "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd"; with "file://path/to/your/dtd/stuff/web-jsptaglibrary_1_1.dtd" Making sure the DTD is installed there (of course).

I've never managed to get a mySQL connection pool going without having to provide at least a password. I am not sure wether this is a bug or a feature. Maybe a different connection pool would provide such feature? -- Nicolai P Gubahttp://www.gnu.org http://www.frontwire.com mailgo:[EMAIL PROTECTED] mailto:[EMAIL PROTECTED] GSM: +44 (0)7909 960 751 DDI: +44 (0)20 7368 9708 ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
