[JBoss-user] [Installation & Configuration] - finding the number of active users
To all: Is there a way to find out how many active users are currently logged into an application using jmx-console? Or do you need to create a program that will keep track of the number of users? Thanks.

[JBoss-user] [Persistence & CMP/JBoss] - Optimizaed loading question
To all: System: JBoss 4.0, EJB 2.0 On a customer's database I was testing out an EJB bean for a view. I noticed that the transaction was timing out because it took too long to get the data (there is about 4,000 records for the table). On the test servers where the data is smaller the beans work fine. I tried using load groups and on-load strategies introduced in the Administration document (Chapter 11). But that did not improve performance at all. I also tried using normal PreparedStatments instead of EJB and this took too long too. The following is a code snippet from my jbosscmp-jdbc.xml. Did I miss anything? basicweb status wireCenter utNum clliCode payback histCost trackUnit ejbSelectGeneric java.lang.String java.lang.Object[] on-load 100 basicweb In my local test server the server log did indicate that the load group did get the primary key fields and the fields defined by the load group. Please let me know if I missed anything. Thank you.

[JBoss-user] [Persistence & CMP/JBoss] - Re: Why the multiple sql select for findByPrimaryKey JBoss
By setting read-ahead strategy to none you default it to the lazy-loading and it will do the multiple select statements. Try checking Chapter 11 "Optimized Loading" of the Administration document. This chapter explains the loading optimization.

[JBoss-user] [EJB/JBoss] - Re: accessing different instances of a database
Thank you for your replies. I tried deploying two different EAR files with two different datasources. The two EAR file has one bean that have the same name. When I tried to deploy it on the same machine, it returned an error javax.management.InstanceAlreadyExistsException For my problem, since the database schema is the same, I would need to rename all my beans and this could easily lead to maintenance issues. For now, I asked my manager if there was another machine where I can install JBoss and keep the EAR files separate. This way the URL would become: http://machine1:8080/dwm http://machine2:8080/dwm View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3873223#3873223 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3873223 --- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

[JBoss-user] [EJB/JBoss] - accessing different instances of a database
To all: System information: JBoss-4.0.0, Windows XP Pro, Database: Oracle 9i I apologize in advance if I posted this in the wrong forum. I?m trying to solve a problem where I have a web application that needs to access two different instances of a database (ex. we call the instances dwm1 and dwm2) that reside on the same machine. These two databases have the same exact database schema but the data might be different. The reason why there are two different instances is because a company was acquired and the database is kept on the same machine but the data is kept separate. The data that I would get from my web application has to be kept separate. Since the database schema is the same, I have one application EAR file which I would like to reuse for the two instances. To make a distinction between the two, I was thinking of having two different contextroot so it would access the two different instances. http://localhost:8080/dwm1 http://localhost:8080/dwm2 Is there a way to do this? If I were to make different EAR files and deploy it, it will probably cause conflict due to duplicate beans. Thanks you.

[JBoss-user] [EJB/JBoss] - Re: JBossQL, XDocletTags, and Date fields
Thank you for replying. I'm using Oracle9i. My problem is that whenever we tried to do a search based on a date field (ex. 1/27/2005). It works if the time was 00:00AM but it will not work if the time was 03:59AM. For testing purposes, we set up a dummy database table with a bunch of date fields (Date, TimeStamp). And for my EJB I tried to use java.sql.Timestamp, java.util.Date, java.lang.Long. When we tried to make a straight forward EJB-QL (select object(c) from TestDateSchema as c where c.tstampDate =?1) JBoss had problems parseing it. We also tried to see if it would work for dynamic queries but that didn't work either. Next, we thought it might work with JBoss-QL since it supports time information, so we changed the XDoclet tag from @ejb.finder => @jboss.query and this time it could not find the finder method. When we checked the ejb-jar.xml the finder method was empty and jbosscmp-jdbc.xml had the finder method. For your database do you have two date fields for start and end date/time? Have you ever tried searching based on a single date field? Since we do our search based on one date field we tried doing: select object(c) from TestDateSchema as c where c.dummyDate between ?1 and ?2 where ?1 and ?2 is equal to 1/27/2005 00:00AM and 1/27/2005 23:59PM so we would get data for that date. Thanks for all your help.

[JBoss-user] [EJB/JBoss] - JBossQL, XDocletTags, and Date fields
To all: System: JBoss-3.2.4, Eclipse 2.1.3, Lomboz 2.1.3 I was trying to create a finder method for a date field using JBoss-QL, since EJB-QL's support for date is restricted (problems with time information). I thought I could create the finder method using Xdoclet's @jboss.query tag but the compiler returned an error saying that the query method can not be found. I checked ejb-jar.xml and jbosscmp-jdbc.xml. It looks like the finder is put in jbosscmp-jdbc but ejb-jar.xml no longer has the finder method defined. Is there something I need to do?

[JBoss-user] [EJB/JBoss] - Re: EJB QL and time comparison
Thank you for the replies. The application that I am working on tries to do a search by the name of the table fieldname and the value. I discovered that when I try to do a search on a date (ex. 01/27/2005), I will get data for 01/27/2005 00:00:00AM. And it did not get data for other times (ex. 01/27/2005 15:59:00 PM). Which is why I needed to pass time stamp information. When data get inserted, the time information must be kept so that we can calculate how long it took for the job to be completed. I will try the java.sql.Timestamp. Worst comes to worst I think the other option would be to get all the data first and iterate it in a loop, get the date fields and convert it to a string, and compare the string values. Thank you for all your help.

[JBoss-user] [EJB/JBoss] - Transaction XAOracleDS vs OracleDS
To all: Before I posted a topic: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=53288 where I was having a problem where transactions did not update the database instantaneously. I solved the problem by using OracleDS (the usual Oracle driver) instead of the recommended XAOracleDS (the XA Oracle driver) mentioned in the document "Getting Started with JBoss". Once I started using the usual Oracle driver the database did get updated instantaneously. I tested insert and rollback and both worked. If I use OracleDS instead of XAOracleDS will it cause any performance problems? Right now I'm in a test environment so I am about the only person using it. I don't know if it will still work well in a production environment where there are hundreds of people using it. If anyone can point me to any other documents, web-sites that explain the differences I would really appreciate it. Thanks in advance for all your help.

[JBoss-user] [Persistence & CMP/JBoss] - transaction does not commit after server shutsdown
To all: I use: JBoss 3.2.4, Lomboz 2.1.3, Oracle 9i, WinXP I have web page project that adds data to a database table and show the contents of the table in the web page. I used CMP beans and I used CMT for my transactions. I tried to test what would happen if I shutdown JBoss. I did the following: 1. Add data. Once everything goes well I display the table in a web page. 2. I confirmed that the data shows up in the table. 3. I turn the JBoss server off. 4. Turn JBoss back on, and access the web page again and the data that I added is no longer shown. Shouldn't the transaction survive the server shutdown? If I let the server keep on running the web page will show the new data and the database will get updated. Also, I noticed it takes a long time for the database to get updated (~30minutes). Does this have an effect on whether or not the transaction survives a server shutdown? Thanks in advance for any help you can give me.

[JBoss-user] [EJB/JBoss] - Re: concurrency issue NoSuchEntityException
To all, I might have fixed the problem. However, I don't know why it worked. For my facade I put a xdoclet tag: "transaction-type=Container" This was something I found in a book "Enterprise JavaBeans" by Richard Monson-Haefel. Also, instead of using findByPrimaryKey() I created another finder method that will find data by the primary key. For example, the primary key was "geoUnitKey" and I created a finder method called findByGeoUnitKey(). I was just experimenting and it worked. Has anyone else experienced this kind of problem and did something similar? Can anyone tell me the technical reason why this works? I haven't figured it out yet.

However, I get the error: NoSuchEntityException: javax.ejb.NoSuchEntityException: Entity not found: primaryKey=14154 Basically, I can not edit data that was recently added. Also, sometimes I am able to add/edit without a problem. I've looked up some web sites regarding the error but was unable to find a solution that was good. Has anyone else got this kind of problem?

[JBoss-user] [EJB/JBoss] - JBossQL and DynamicQL
To all,
I was trying to implement a generic finder method that I found in :
http://www.mailarchive.com/[EMAIL PROTECTED]/msg05474.html
The goal was to pass select statements that you define yourself. (My code is at the
bottom.)
When I deploy it, I get the error:
11:04:49,055 WARN [verifier] EJB spec violation:
Bean : DWMUsrAdmin
Method : public abstract Collection findGeneric(String, Object;) throws
FinderException, RemoteException
Section: 10.5.6
Warning: Every finder method except findByPrimaryKey(key) must be associated with a
query element in the deployment descriptor.
Since @jboss.query is set to dynamic I thought that the query will be overridden and
having an empty query will not cause a problem. I checked the ejb-jar.xml and the
only thing that might be a problem was:
Is there something I am doing wrong?
I am using JBoss 3.2.4.
Thanks in advance for any help you can give me.
I have the following in my Bean:

[JBoss-user] [EJB/JBoss] - EJBQL and EJB 2.0 and Order By
To all, I'm using JBoss 3.2.4 and EJB 2.0. I have a EJBQL statement: "select distinct object(usr) from DWMUsrAdminSchema as usr, in (usr.userComp) as uComp where uComp.componentKey =?1 order by ?2 ". I read in another thread that JBoss extends EJBQL so that "order by ?2" would be legal even though it is EJB 2.0. When I deployed it, it returned errors. I also tried @jboss.query tags but it returned the same errors. The select statement worked only if I specify the field name for "?2". Is there a way to update EJB 2.0 to EJB 2.1 so that "order by ?@" works? Thanks in advance for any help you can give me.
