Been trying to get this to work, but no luck. How do you use JbossQL with Xdoclet for an EJB.SELECT? The following does not work, and some of the mailing lists mention that jboss.query is NOT for SELECT (SELECT is method level while jboss.query is class level), so what would one use? /** * @ejb.select *signature=java.util.Float ejbSelectStoreSum(java.lang.String store, java.util.Date theday) *query = SELECT o.amountpaid FROM Store AS o WHERE ((o.store = ?1) AND (o.transday=?2)) * @jboss.query *signature=java.util.Float ejbSelectStoreSum(java.lang.String store , java.util.Date theday) *strategy=none *query = SELECT SUM(o.amountpaid) FROM Store AS o WHERE ((o.store = ?1) AND (o.transday=?2)) **/ p.s. seems silly to declare an ejb.select for a JbossQL SUM that you know will not work as expected outside of Jboss.

[JBoss-user] RE: Challenge for EJB-QL, JBossQL, or declared SQL?
I imagine ORDER BY is part of it, but the harder piece is getting the last sequence per batchnumber and THEN return that collection of objects (see example results below). Regular SQL would be something like SELECT batchnumber, MAX(sequence as MAX_sequence) FROM thetable ORDER BY batchnumber for JUST getting the last sequence number. You still have to do a JOIN or SUBSELECT from this query to attach to the actual search critera (item = foo or what-have-you). Then, the end result is still to return a collection of EJB local or remotes. Is there an elegant, object-oriented way of handling this kind of scenario? A 'J2EE' way of handling it? -D Subject: RE: [JBoss-user] Challenge for EJB-QL, JBossQL, or declared SQL? From: [EMAIL PROTECTED] Date: Thu, 6 Nov 2003 10:52:24 +0100 ORDER BY works in JBossQL.

[JBoss-user] Frustrated with CMR on Jboss
Hey all, been banging my head on CMR for couple of weeks now, and since my desk broke it's about time to ask the mailing list for some help ;-) If you have a 1-N relationship between, say, an Organization bean that has many Gangsters. And, let's say you want to return a collection of value-objects of the Gangsters for use in Web/Thick-Client/what-have-you. I would think you would simply have something like: /* *CMR Relational Methods */ /** * @ejb.interface-method * view-type=local * * @ejb.relation * name=Organization-Gangsters * role-name=one-organization-has-many-gangsters * cascade-delete=no * * @ejb.value-object * aggregate = com.mycompany.entity.interfaces.GangsterValue * aggregate-name = AllGangsters * match = * * members = com.mycompany.entity.interfaces.GangsterLocal * members-name = Gangsters * relation = external * type = Collection * exclude=true * * @jboss.relation-mapping style=foreign-key * */ public abstract java.util.Collection getGangsters(); And then call Organization.getGansters(). But no...you get the stupid-ass 'CMR can only be used in the transaction in which it was created'. Ok, so use a method that puts them in ValueObjects - with Xdoclet it will also create the aggregate method called getAllGangsterss() for the OrganizationValue object that will return a collection of GangsterValue objects, but that ALSO comes up with the same error. I've gone through the mailing lists and the forums, and there was a reference to using UserTransaction, but that caused some issues when pushed beyond one concurrency (and doesn't seem like the best solution). I remember someone stating this is how it is supposed to act in regards to specs, but that does not make sense - how do you get the information out?

RE: AW: [JBoss-user] JBoss: Not Ready For Prime Time
Thank you Dr. Christoph, this seems to be going towards the actual crux of the conversation, and very good stand. From my standpoint, going use a non-technical example, people buying furniture... *Some people like to buy nice, warranted, expensive furniture for their home, ready to go and shipped to their house and transported in and setup. If something fails or breaks during transport, moving it in, or setting it up, they can demand a replacement or compensation. - FULL SERVICE *Others go to the local store, get something that works for them, and move it themselves and then expect nothing to go wrong until it is time to replace it, or it is asked to do more than expected. - EFFICIENCY *Then there are the people who will get unfinished/unassembled furniture at relatively low cost and put it together themselves. Maybe make their own little changes like different color/laquer, or maybe do a little woodwork or upholstry to meet their needs. - SELF SERVICE *Last, and not least, are those people that will start with paper and pen tools to design what they want, research and identify the tools and materials they need, then spend time building exactly what they want or what other people may want. - I WANT A RECLINING, MASSAGING, HEATED COUCH WITH BUILT-IN REMOTE, MINIFRIDGE, AND A CUP-HOLDER THAT WILL FIT MY BEVERAGE. It is these last people with innovations that make our world go forward, challenging ideas, making a better life for those of use who may want SELF SERVICE, EFFICIENCY, or FULL SERVICE. Open Source is unique in that it can offer tools for most, if not all these people at lower costs then elsewhere. There are FULL-SERVICE contracts using open-source software available, including JBoss if this is what you are looking for. p.s. As for the Axis comment, I think everyone that has decent technical experience realizes that the JBoss.Net/Axis project is new, unique innovation, attempting to reduce development time by making single POJO (Java Objects/Classes) that can be used both in the Java/EJB world *AND* the Web Service world through Axis, all through the same platform.

RE: [JBoss-user] Store large pdfs with JBoss
Just throwing in my two cents - Outside of JBoss, with Content Management Systems, the most common problem is how to handle large amounts of data, which is the case here. With databases, you have to scale your server up to handle it. With a Filesystem approach, you can take advantage of HSM - Hierarchial Storage Management - to manage the large amounts of data. You create/add files to your environment, and at some point they reach a state where the file will no longer change (maybe right after creation) and will not be requested frequently (ready to be archived). Usually you can figure out that in your environment a plan - for instance, after a file has been added it is less-frequently requested after 90 days. At this time, you can burn those files to CD or DVD and put them in a jukebox, migrating to a less expensive and less fast storage environment. After 3 years, store offline on tape. Just an example, your environment will be different. The best approach to this is to have two keys in your database - one that is the unique identifier of the file you are looking for, the the second is the actual pointer to the file. This way, if you HSM and move files to CD/DVD, you're system still maintains integrity of the unique identifier for lookups, but the pointer can change as-needed. You can also archive your files offline on tape and just have a pointer that will bring up a 'quickfind' page of the location, vault #, box #, tape #, and file to find the stored offline file. There are a lot of content management/HSM products already out there, but I personally have not found one within Open Source world that would satisfy my requirements, maybe you'll have better luck and share with us? :-) two cents, -D, CDIA+ - Guy Rouillier [mailto:[EMAIL PROTECTED]] wrote: Just store areference to a location in the filesystem, and keep the binary files in the filesystem. You can back up your filesystem as easily as you can back up your Oracle logs. I tried this for a content management system I worked on once. We had terrible problems keeping the database and the filesystem in sync. For one thing, the database is transactional; the filesystem isn't. You can roll back an operation on the database, but not on the filesystem. Therefore, if your application crashes, you've lost all guarantees of referential integrity, which a database by itself can provide. If you have everything in the database, you can back it up by using the database's own replication facilities to create a mirror, without shutting down the application. But if you keep your PDFs in the filesystem, the only way to be sure of making a consistent backup is to shut down your application, because you need to make sure that (a) there are no files that containing data for uncommitted transactions, and (b) all the files for committed transactions have been written. Also, most filesystems are notoriously poor at storing huge numbers of files in a single directory. Even if you store files in subdirectories and sub-sub-directories, you'll be limited by the speed at which your filesystem can traverse directory hierarchies and match filenames. Different filesystems may or may not be optimised for that sort of access. Databases, on the other hand, are designed to quickly store and retrieve items in tables containing millions of rows. Every time you do a full database backup, you are going to be backing up that same, **unchanged** 20 GB of PDFs! In most databases, most of the data remains invariant most of the time. So this point applies to most databases, not just the ones that store PDFs. The answer is not to do full database backups; instead, use the database's own replication facility, which is designed to do this job efficiently.

Re[4]: [JBoss-user] Optimistic locking ported to JBoss-3.2
Ah, thanks Alex! Unfortunately, answering some questions lead to more questions for even better understanding ;-) Using the Version Strategy as an example, if you have one app server talking to one database (equiv to commit-option B), will this make mostly-read transactions better or not make that much of a difference? Actually, now that I'm thinking about it, would someone help enlighten my dim LED with a simple layout about when this cool Optimistic-Locking would offer the best results, and when it is not (I assume highly-volatile Tx entities would not, but assuming equals ass-u-me)? Single JBoss, Commit-Option A, D --Read only entities, mostly-read entities, and highly-volatile entities Single JBoss, Commit-Option B --Read only entities, mostly-read entities, and highly-volatile entities Multi-Jboss Cluster, Commit-Option C --Read only entities, mostly-read entities, and highly-volatile entities Gone through Dain's great JbossCMP pay-for docs, well worth it! DJ I don't understand how this works yet. I'd really appreciate a detailed DJ explanation of what happens when 2 threads/transactions simultaneously DJ access one entity. I'd like to know what state the jboss entity values DJ are in and what state the database is in at all points of such an DJ interaction. Well, I'll try to explain. Suppose, we use version column strategy, i.e. counter column that will be increased by 1 after each update. Now, suppose, there are two concurrent clients running in each own tx trying to modify some data in the same entity. When tx from the first client reaches the entity, i.e. when the first client reads or modifies some data of the entity, JDBCOptimisticLock locks the version field. That means it stores version field and version value. It stores it in a TransactionLocal, similar to ThreadLocal but keyed by tx. Ok. Suppose the first client continues with its tx. Now comes the second client with its own tx. Again, when this tx reaches the same entity, JDBCOptimisticLock does the same thing as it did for the first tx, i.e locks version column and value and stores it in TransactionLocal. Note, that it deals with not modified by the first client version of the entity. At least, my tests show it. But I'd would appreciate others to try it. Then, suppose the second client stores the entity, before the first client. The changes made by the second client are persisted and version number is incremented. Then, the second client commits its changes. But as the version value locked differs from the value in the db, it fails. Hope this one is better. alex --- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

Can you send me this code so I can test with a profiler? I want to know where all the time is spend. What version of JBoss are you using? I am not interested in any CMP vs non-CMP debate. TSS may be a better place for this. Agreed. It would be convenient, if the size of the result sets, that can be handled using CMP, coincides with the number of rows you should/could reasonably display in a dialog or page in your (web-based) GUI. This would remove the need to switch to raw JDBC, when doing the CMP equivalent of plain vanilla (for instance) select * from BeanTable where lastUpdate = '10/20/2002' queries. That's all I hope for. You lost me. JBoss 4.0 will have support the LIMIT someNumber OFFSET someNumber syntax. Is that what you are talking about. I would like to be able to support Date literals, but I don't want to get too far in front of the spec. Does anyone know where I can find the ANSI SQL spec on date literals?

[JBoss-user] False-positive LDAP Authentication when no password entered....also TLS?
Hi all, Running Jboss 3.0.1RC1_Tomcat with OpenLDAP 2.0.21 LDAP backend. Other applications are using this LDAP backend and do not have any security problems, isolating to just this troublesome Web Application. ;-) Running into an issue with supposedly Secured Web Applications during authentication. If the user puts in an authorized (not to be confused with authenticated) username but no password on the browser security pop-up, they get authenticated into the web application (even though that user DOES have a password). Have tried on most recent IE, Netscape, and Mozilla browsers, so not a browser problem. Also seems to do false-positive authentication if the user has a long password but puts in only the first 8 characters. TLS seems to also not work correctly, but I think I might be missing a configuration piece, just not sure where...the LDAP server is setup for TLS and TLS does work with other applications, but JBOSS applications continue to use cleartext across the wire. Now, has anyone else also run into these issues and/or can confirm these issues? I'm only one guy trying to get things locked down, want to make sure it isn't my ignorance. :-) What JBOSS logs say: - DEBUG [org.jboss.security.auth.spi.LdapLoginModule] Bad password for username=null - Here is the testLDAP config snip from login-config.xml: application-policy name = testLdap authentication login-module code = org.jboss.security.auth.spi.LdapLoginModule flag = required module-option name = java.naming.factory.initalcom.sun.jndi.ldap.LdapCtxFactory/module-op tion module-option name = java.naming.provider.urlldap://myldapserver_removed//module-option module-option name = java.naming.security.authenticationsimple/module-option module-option name = java.naming.security.protocoltls/module-option module-option name = principalDNPrefixuid=/module-option module-option name = uidAttributeIDuid/module-option module-option name = roleAttributeIDemployeeType/module-option module-option name = principalDNSuffixtree_removed/module-option module-option name = rolesCtxDNtree_removed/module-option /login-module /authentication /application-policy jboss-web.xml for Secured Web Application: -- jboss-web security-domainjava:/jaas/testLdap/security-domain /jboss-web Snip from web.xml for Secured Web Application: - security-constraint web-resource-collection web-resource-nameSecure Web Application thingy/web-resource-name url-pattern/*/url-pattern /web-resource-collection auth-constraint role-nameMySecureRole/role-name /auth-constraint user-data-constraint transport-guaranteeNONE/transport-guarantee /user-data-constraint /security-constraint login-config auth-methodBASIC/auth-method !--auth-methodDIGEST/auth-method -- realm-nameSecure Web Application/realm-name /login-config security-role descriptionsome description/description role-nameMySecureRole/role-name /security-role END DISTRESS CALL FOR HELP :-P --- This sf.net email is sponsored by: OSDN - Tired of that same old cell phone?
