[JBoss-user] Please Help Me
Hi all , I really hope i will get a reply this time i have been struggling with this for quite some time My application uses a JTree to help ease the navigation through the whole application. The problem i am facing is that , it is authenticating the users present in the LDAP Server. But when it is trying to initialize the applet it is asking once again for the username and password (saying enter the network password!). There even if i give junk values it accepts ... even if i don't give any values it makes no difference. I have to click on that login pop up at least 10 times , then it allows me to enter the application, else the left side JTree Appletdoesn't show up at all. Because of this my application is not getting authenticated. It is saying the principal is null ... see the Exception, java.lang.SecurityException: Authentication exception, principal= at org.jboss.ejb.plugins.SecurityInterceptor.checkSecurityAssociation(SecurityI nterceptor.java:173) at org.jboss.ejb.plugins.SecurityInterceptor.invokeHome(SecurityInterceptor.jav a:94) at org.jboss.ejb.plugins.LogInterceptor.invokeHome(LogInterceptor.java:129) at org.jboss.ejb.StatelessSessionContainer.invokeHome(StatelessSessionContainer .java:300) at org.jboss.ejb.Container.invoke(Container.java:730) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:517) at org.jboss.invocation.local.LocalInvoker.invoke(LocalInvoker.java:98) at org.jboss.invocation.InvokerInterceptor.invoke(InvokerInterceptor.java:102) at org.jboss.proxy.TransactionInterceptor.invoke(TransactionInterceptor.java:77 ) at org.jboss.proxy.SecurityInterceptor.invoke(SecurityInterceptor.java:80) at org.jboss.proxy.ejb.HomeInterceptor.invoke(HomeInterceptor.java:198) at org.jboss.proxy.ClientContainer.invoke(ClientContainer.java:76) One possible explanation that i got is that it is trying to get all the jars needed by the applet from the server , hence is trying to authenticate each time. Is there any way to avoid this?? Why is it trying to authenticate the applet in the first place.Since i have already defined all the permissions for the applet in the Policy file. I hope i have been clear in explaining my problem to you. Please let me know If there is some other configuration i need to do.

Re: [JBoss-user] Please help me! Transaction problem
From where does EditStudentInfoAction get its session bean reference? Does it create a new one for each request, or does it create just one and try to re-use it for each request? The latter situation is guaranteed to cause the problem below. If that is not the cause, then show me your implementation of EditStudentInfoAction.execute.

Hi All. I have got one problem and I can't get the right way. I have database and I wrap this database with EntityBeans. But now I need build report and I need summary information (in SQL: select sum(myColumn) from myTable group by myID) I see any ways how to do it. 1. Build the new EntityBean which will execute SQL and will represent summary information (but I see something wrong here) 2. Build a SessionStateless bean and execute SQL to get this summary information 3. Build SessionStateless bean to get data from my EntityBean-s and group this data manualy.

Re: [JBoss-user] Please help me ...
Aggregate queries are usually best performed by a SLSB using an SQL statement. One exception is if the query range is a small number of records whose corresponding EBs can be readily activated by a finder, e.g. a sum over a user's account balances where the account EBs are fetched by a UserHome finder. The finder alternative is esp. appropriate if the use case calls for a subsequent drill down into the detail EBs. Moral: depends on the app usage model, as usual.

I agree with the Fred that the SLSB is the better route and cleaner overall. In any event, you are only going to return an int. So, in your remote interface add a public int getXYZ() ... and then add the same to the Bean. The following is from a SLSB but the same would work in a Entity Bean. Note: we put the name of our datasource into an env-entry rather than hard code; you wouldn't need to do this.

Title: RE: [JBoss-user] Please help me ... Andrius, Good point, then it comes down to what you are trying to get the sum of. I have tables w/ million+ active records, multiple containers, commit-option=B/C and our sums/counts are of big results so the collection route was a bad thing (for me). Even so I'm wondering, on smaller collections how would jboss know that it had all of the records that qualified for the query unless it was a result of a finder method for which the results were still cached? It seems like it would still have to go back to the DB and re-retrieve the keys to verify against the cache. john -Original Message- From: Andrius Juozapaitis [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 24, 2001 10:04 AM To: [EMAIL PROTECTED] Subject: Re: [JBoss-user] Please help me ...

Re: [JBoss-user] Please help me ...
Any time you call a finder there's at least one hit on the database, for that very reason. Even with commit option A, the container hits the database to get (at least) the keys. -danch John Moore wrote: Andrius, Good point, then it comes down to what you are trying to get the sum of. I have tables w/ million+ active records, multiple containers, commit-option=B/C and our sums/counts are of big results so the collection route was a bad thing (for me). Even so I'm wondering, on smaller collections how would jboss know that it had all of the records that qualified for the query unless it was a result of a finder method for which the results were still cached? It seems like it would still have to go back to the DB and re-retrieve the keys to verify against the cache. john -Original Message- From: Andrius Juozapaitis [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 24, 2001 10:04 AM To: [EMAIL PROTECTED] Subject: Re: [JBoss-user] Please help me ... RE: [JBoss-user] Please help me ...IMHO slsb + entity bean collection approach looks like a better and more universal one. with jboss caching the entities, you might not get a db hit at all. and if your data is more or less static, there is a way to use read-only entity beans, look in the archives for more info on this regards, --andrius - Original Message - From: John Moore I agree with the Fred that the SLSB is the better route and cleaner overall. In any event, you are only going to return an int. So, in your remote interface add a public int getXYZ() ... and then add the same to the Bean. The following is from a SLSB but the same would work in a Entity Bean. Note: we put the name of our datasource into an env-entry rather than hard code; you wouldn't need to do this.
