Re: [JBoss-dev] JDBC SQL Extensions
When it comes to the outer joins I would be vary careful if not try to
avoid them altogether. The SQL spec is washy at best and I believe that
each vendor does it a little differntly , PostgeSQL only added outer
joins in version 7.1.
The IS EMPTY cluase ... after reading the spec are they assuming that
you are checking if an obects collect is empty or are you looking for
all ojects that empty collections? Either way I would look at the exists
clause.
Dain Sundstrom wrote:
all JDBC experts,
Is it common for the JDBC drivers to support the SQL Extension functions?
http://java.sun.com/j2se/1.3/docs/guide/jdbc/spec/jdbc-spec.frame11.html
I specifically need the functions: concat, substring, locate, length, abs,
and sqrt.
I'm planing on mapping these to {fn concat('str1', 'str2')} style functions.
If it is not common to support these fuctions I'll write a function map spec
in the xml.
Also, do most vendors support the {oj outer-join} syntax like:
SELECT *
FROM {oj order LEFT OUTER JOIN line_item ON
order.ordernumber=line_item.ordernumber}
I think I need this to support the IS EMPTY operator in queries like:
SELECT OBJECT(o)
FROM Order o
WHERE o.lineItems IS EMPTY
Thanks for any help
-dain
P.S. I just found some docs that say that Oracle drivers do not support any
of these portability features (my words). Does anyone find this
supprising? (I'll keep my feelings on this to my self). Any way, if it is
true, I'll implement this the hard way after I get the easy way working.

Sorry for the confusion. There are two issues here.

Issue1: use of the {fn concat(str1, str2)} style functions.
Solution: use fn style functions as default but have override in xml like:
concat-functionCONCAT (?1, ?2)/concat-function
or some thing simmilar.
==
Since I have only used the PostgreSQL driver hard to say how other
vendors JDBC drivers are but have heard lots of comments about Oracle
I would suggest you try and code to the lowest JDBC version and
wrap up the strange bits in the xml (more jaws stuff). For example in
Postgresql, concat is || so ..
concat-function?1 || ?2/concat-function
Looks like the way to go ... (Dam more work!)
Issue 2: IS EMPTY function. How should I map the following ejb-ql query:
SELECT OBJECT(o)
FROM Order o
WHERE o.lineItems IS EMPTY
Solution A:
SELECT o.ordernumber
FROM Order o
WHERE NOT EXISTS (
SELECT l.pk
FROM Order o, LineItem l
WHERE o.ordernumber = l.ordernumber)
I like this because it does not use an outer join (thanks Dave Smith). Does
it have performance problems?
Solution B:
SELECT o.ordernumber
FROM Order o LEFT OUTER JOIN LineItem l ON o.ordernumber = l.ordernumber
WHERE l.ordernumber IS NULL
This would be a major pain to map to all vendors.
Either way the query will have to read the entire order file to check
the lineitems . I would get it working first then optimize, might be
there but not offen used.

Re: [JBoss-dev] SQL function mapping
Dain
I added the function mapping code to the EJB-QL to SQL translation engine. I
added mappings for MS SQLServer, Oracle, MySQL and PostgreSQL to the
standard jboss cmp xmp file.
Notes:
- These mappings are completely based on info from the 'SQL in a Nutshell'
book, so they may not work (I don't use any of these databases).
- PostgreSQL doesn't have a three argument position function, so I didn't
It is simply two functions
position(?2 in substring(?1 from ?3))+?3
map it.
- Send me any corrections or change it your self.
- If not mapping is provided the system defaults to {fn concat(param1,
param2)} style functions.
The mappings follow this message.

The jaxp stuff is buggy with CL and it needs the local path stuff right now. I talked to their developer a couple of days ago (SUN kiddy, wouldn't cut it a day here ;) and they say the new version on apache fixes that. Same with log4j (g!) same ol' sun... don't know jack! lib/ext libraries are those loaded over the network. The ones we are talking about need to be present (the ones in lib). I think we could rename it /lib/boot and lib/services to be more explicit, I think lib/ext is confusing to many people. The jboss-service.xml should not reference lib/ stuff and if you don't specify a codebase it points to http/file://yourinstall/lib/ext... we could move that to yourinstall/lib/services what do you say? marcf So the upshot is ..for a network load you still need those three jars locally becuase they do not want to play nice with the CL.

Relax. The only reason you need the jbosscmp-jdbc.xml file is that you are
tiring to exactly specify the foreign key field. If you just let the system
define the foreign key field for you, you would not have any problems. I
have a test case that closely matches what you have coded except my case

So let me understand the order case above. Would the database schemas
look like this?
create table order (
objectid int default nextval('some sequence') primary key,
other fields ...
);
create table order_detail (
objectid int default nextval('some sequence') primary key,
order_oid int references order,
line_numint
other fields ...
);
Still having a hard time why you have to auto generate fk fields for
this case. It would seem this is what a dba would give you ... and if
the order/order_detail objects had all of the fields above nothing to
generate?
I think that your code is handling all of the difficult cases and is
ramming the easy ones into it. We really should have a waterfall type
style where we assume that it is the simple case and then have the
program add what's missing or have the user define it.
We should avoid creating tables if all possible. I would see only 3
cases where you need a third table
Many to Many
1 to Many (unidirectional. I can not come up with an example but it
would be valid)
Self referencing entry
A relation table is only required for a many-to-many relationship. A
unidirectional many-to-one relationship can always use foreign keys. The
trick is that the database mapping of the relationship does not have to
match the object level navigability. A self-referencing entity can also use
a foreign key to itself.
Time passes ...
I'm am really trying hard to not have to use this jboss-jdbc.xml ... For
composite foreign keys would could also the jdbc method
getImportedKeys() to figure out composite keys. This would mean the jdbc
driver would have to support the DatabaseMetaData method and the dba
would have to use the references in their table definition. We could
always fall back to the xml file if it did not exsist. So with a good
jdbc driver we really would only have to create an xml entry if we had a
specfic relation table we had already predefined.
This is a good idea but, would only work if there were only a single
relationship between the two entities. The problem is that it is very
common for entities to have multiple relationships. For example, order has
a shipping address and a billing address.
So what. There are two foriegn keys on a table. Could be hundreds ..

Re: [JBoss-dev] EJB 2.0 CMP
Got it now ... but it is still not seeing eye to eye ... comments below .. Dain Sundstrom wrote: Dave, We still don't see eye-to-eye, and I think I made the problem worse with my example. I think the most common type of relationship will be something like 'a cd has an artist' or 'a cd has a publisher.' In this cases, the foreign key for the artist or publisher would be just another column in the cd table. So we would have something like: String idbn pk String title ... Oid cd_artist fk Oid cd_publisher fk The oid is a place holder for what ever the pk for cd and artist (don't let it confuse you). I will argue that this is the most common relationship type and is auto created by the system. Sure, Oid could be artist number, name Now your mapping is very different from what we have above. Your mapping mapps a foreign key to one of the pk columns (multi-key). This is a very difficult mapping because of the way the cmp engine is architected. The CMP engine is field oriented as apposed to column oriented. A field can map to multiple columns (a feature that existed in jaws). Follow so far? Not a good database practice to have one field name map to multiple database columns, but you have to support it. I would suggest though most IDE's would map 1 column in the database to 1 field in the entity and that case should be the rule, not the exception. Now each entity is composed of a collection of cmp field field objects and a collection of foreign key fields (or relation table key fields). I'm only going to address foreign key fields here. When the system starts it initializes the cmp fields for every entity. After that is complete it initializes the relationships. For each cmr field in an entity, it locates the related entity and creates a set of foreign-keys that are a copy of the related entitie's pk field(s). Still with me? I'm with you but I think this is the rub. Why are we creating a copy of the related keys? Since you alredy have to create the actual implementation of the data for the entity bean, you must have code to map setfield and getfield calls into a set/retrive data out of the entity. Why not map the reference in the foreign key object to the entiy field and then just get it when you need it? Do they both not have to be in sync at all times anyway? The problem you mapping presents is you want to use a field for both an entity cmp and a relation foreign key field. In the current code these fields are different object. The caching code is also field oriented, so you would end up with two distinct caches of the code. Which could be a big problem. See above. Ok let's take a step back and examine the mapping from the spec perspecitve. Using a pk field as a relationship foreign key presents a problem because the spec requres that a pk never change after ejbCreate but also requires that a relationship can not be set until ejbPostCreate. This leads to the question, how exactly are you going to set the relationship? Any way, I don't think any of the above text is that important. Although I think what you ask will make your code not spec compliant, I also think this type of mapping is important. I will look into adding support for this type of mapping, but it won't happen soon. I am focusing on the features required for spec compliance. Then I am going to add performance enhancements. And finally additional features. Yup, thats a problem. Looks like we would have to use 10.8.3 to get around it. I would not have a problem sticking in an primary key oid to get around it but it is just extra table space. I would agree though that unless it is easy to implement this would be a low priority.

[JBoss-dev] EJB/QL - JBoss extentions
Well after doing some paying work I'm back to looking at and testing the new EJB 2.0 query methods. I have taken my current application (not written in EJB) and tried to convert some of it into EJB. I have come across the following problems/holes in the EJB/QL spec. Below is a summary of the key problems with examples. If I'm way off base please say so! 1. No order clause. Well ... this is obvious and I have not tested the current stuff to see if Dain put it in. 2. No limit/offset or cursors. In a word searches. If you are tring to search for something you display a list of current values based on a selection criteria. What happens when the list is 100,000 records. With current DB code you would declare a cursor or use offset and limits and only retreive a bit at a time. 3. Dynamic where clause Prompting the user for a search criteria and returning a result set based on those criteria. Also would be handy to have cursors/limit. 4. database functions If I am doing a query on a datestamp type field but I only care about the date part, in postgresql I need to use a postgresql function that only returns the date. For 1,3,4 I would propose that we add a special jboss function into the QL, something like jboss_sql_inline() and what is between the brackets is just passed through to the sql engine. Arguments could be passed through to parts of the code with ??1 etc, sort of an escaped argument. So you could have select object(o) from foo o where o.id=?1 and jboss_sql_inline(datefunc(datefield) = ??2) For option 2 could we not extend the Collection type that we return to not only do dynamic object creation but also dynamic lookup, so you would do the query return an empty collection with a handle back to the query. Once the collection was accessed then the requested element would be retreived. I beleive this would have to be a read-only list because if the object is not loaded it can not be locked. This would not be much of a drawback becuase for searches it is usally read only and then the users selects an object he wishes to modify/or view the object is locked. I'm willing to put some time into this. (ie coding) Comments? ___ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development

Close, but what if my initial list is 1 million records. That means that you still have to load and create 1 million pk's. I think you need to define the query and return the list.

Keep the result set open, retieve from the set as necessary, probably using a cursor. That way if someone is doing a search that has 1 million records and after I display the first 10 and the client chooses the 3rd one, we have only created 10 objects.

Re: [JBoss-dev] EJB/QL - JBoss extentions
As normal dain converts my ramblings into good ideas .. Comments below .. I suggest that we add an order element to the query section in jbosscmp-jdbc.xml file. Something like query descriptionFind all orders with the specified status/description query-method method-namefindWithStatus/method-name method-params method-paramjava.lang.String/method-param /method-params /query-method ejb-ql orderORDER_NUMBER/order /ejb-ql /query Note the order element would contain the exact sql that would appear in the order clause. I think that we should require the user to use the sql column names and not support a bean level field ordering. The reason being that it would be difficult to determine how multi column fields would be ordered, and it also allows the user to order by column that are not mapped. Cool . 4. database functions If I am doing a query on a datestamp type field but I only care about the date part, in postgresql I need to use a postgresql function that only returns the date. Date handling is EJB-QL sucks. Here is how you can do it myRef.date = ?1 and myRef.date ?2 Then pass in the day and the next day. The big benefit is its spec compliant. Bad example on my part. I think thought what is stated below will cover it. I don't recommend this. It would make the query engine much more difficult then it needs to be. Just off the top of my head how does this fit into the EJB-QL BNF? What is the type of a jboss_sql_inline function? What is the precedence? What is the allowed text inside of the function? Are path statements allowed? Are parameters allowed? How do we escape things that look like parameters or path statements if allowed? I have been thinking about statements like this for a while, and I think I have a solution that every one will like. I think the real goal is to allow much more complex queries then can be generated from ejb-ql, and to allow optimized queries (hinting). I think the best way is to support raw-sql queries. A raw-sql query would have the following properties: * allow any sql statement * hand mapping of results from selected columns * internal state of parameters may be used I am thinking of an xml spec that is something like query descriptionCount orders with same status as the specified order/description query-method method-nameejbSelectStatusCount/method-name method-params method-paramorg.foo.bar.Order/method-param /method-params /query-method raw-sql sql SELECT COUNT(order_id) FROM order WHERE status = ?1.status /sql results-map ordinal1/ordinal /results-map /raw-sql /query The results-map would have to be much more complicated to support multi-column pk keys and eager loading. The biggest problem with this solution is the raw-sql specification could be very difficult, so to go with this spec we would supply a tool that takes the current ejb-jar.xml (especially the ejb-ql section) and jbosscmp-jdbc.xml files and generates a new jboss-cmp.xml file with all of the ejb-ql statements converted to raw-sql queries. This is part of a tool set that I would like to write to help with the optimization process. It also do things like fill in all of the default mappings of tables. Any way, I think this would allow people who need advanced db features to do whatever they want, and allows us to keep the ejb-ql parser spec compliant. Also it would not be that difficult to implement, because the xml structure is similar to how the internal structure of queries are implemented in the engine. I hope all of this is intelligible. Yup, this is the way to do it. All extra stuff should be in the .xml config file. So with the above syntax for my own queries why not query descriptionMy own hard coded where clause /description query-method method-nameejbMyQuery/method-name method-params method-paramjava.lang.String/method-param /method-params /query-method raw-sql sql SELECT * FROM my_table WHERE ?1 /sql results-map ordinalMany/ordinal return_typeorg.foo.bar.MyTable/return_type /results-map /raw-sql /query As far as generating another file with optimized queries I think this is overkill, confusing and not necessary. With most databases the query optimizations are done at the sql level why not just use the above for queries that need to be optimized. For the

Re: [JBoss-dev] EJB/QL - JBoss extentions
Ok, so 20 or so e-mails later the summary .. 1) Right now if I want to use order I have to use declared-sql with an order by clause but dain wants to add an order tag to the xml config file. 2) For dynamic queries I just use declared-sql and do my normal SQL query. This could also be used if I had some strange SQL functions that needed to be called. 3) For only retreiving a partial list I'll have to use the limit and offset options in delcared-sql and then write some sort of wrapper object that keeps track of the current offset in the table as well as a limit size. So, I'll take my declared-sql and crawl back under the rock I came from. Dave Dain Sundstrom wrote: The example you have given can be done today with declared-sql. Declared-sql is designed to satify 95% of the cases. The other 5% are very important and should be addressed.

Agreed.
The second one is somewhat related. Since a field (really an object type /
class) maps to more then one column you will have an issue with query input
parameters. I suggest something like ?1.prop.prop (more like ejb-ql) or
{1.prop.prop} (I like this one, more like old jaws style, easier to parse).
I was going to write some helpers to extract properties based on a doted
structure, but haven't gotten to it yet.
Hmmm.. I was thinking that you would pass the whole sql command through,
execute it as is and then grab the metadata for the result set and then
try and fill the object. The problem with properties is when you are
doing dynamic queries you don't know how many input parameters you are
dealing with. If your input parameters are static then could you not use
delared-sql ?
So given that there are 48-60 hours in a weekend it is doable, but I would
shoot for 2 weekends. One to get the results half and the other for
parameters.

Scott, I hope you don't mind my quoting some of your technical remarks rather than rephrasing them just to avoid this. After a brief confusion at the outset, Scott realized that I was trying to ask the user for two separate pieces of information to uniquely identify them. I explained that I was planning to add another CallbackHandler and another Principal implementation to facilitate this. He said: Ok, I see the issue. However, when a login module is executed on the server in response to either an attempt to access an ejb or a servlet, there is no callback handler to which the request can be delegated. An extension to the current security manager would have to be made to allow one to configure a callback handler for a security domain. Also, the next logical step would be to have a properties based principal and callback object that allowed one to associate any number of attributes with a principal. The ASP use case is one that just uses a single organization property. Adding this as well as externalizing the callback handler for a security domain makes sense to me. As I said to him, this is more work than I probably have time to do right now, given the other deadlines I am facing, and it seems unlikely to me that this would be a good first project for a new jboss developer even if I did. Perhaps I will be able to contribute to the project in some way at a later time.

Finally, we are on the same page ..not even a blue moon ...
Yup this is a suggestion. I agree 100% we need to avoid using
jbosscmp-jdbc.xml.
Ulitmately at the database level for each table there has to be a unique
column name(s) that acts as a foreign key for the relation. It also
can only participate in 1 relation.
For a many to many relationship with a mapping table could be a problem
if the field name on both sides of the relationship were the same. But I
would see this as an exception not the rule.
For self joins you would have to do like you do in the EJBQL and prefix
the column with the table name. Not a bad idea for all relations so
select uuid from CDTrack where composer=?
would be
select c.uuid from CDTrack as c where c.composer=?

Do you have a jbosscmp-jdbc.xml file that specifies the relationship should

If it is a suggestion, say so, and I will consider it. My main goal when
creating column names it to always allow an ejb jar to deploy without
requiring a jbosscmp-jdbc.xml file. When explaining the suggestion explain

Don't be sorry, be happy ;) the problem is that the name specified in the cmr-field-name is not the database column. Jboss assumes that the database column name is the cmr_field_name (left side) +_ + cmr_field_name right side. What I think makes more sense is for the cmr_field_name by default to match the database column name the same way it does in CMP.

All column names are either generated, or specified in the jbosscmp-jdbc.xml file. Your opinion is that when jboss generates the column name for a relationship fk it should first attempt to the name of the cmr-field abstract accessors. Problems occur when the entity does not have an accessor for the relationship, and when the primary key related entity maps to more then one db column. What is your complete proposal for fk column generation and relation-table column generation? Be specific. Not quite I suggest you use the name of the cmr-field-name in the ejb-relationship. therefore when creating the column the field always has to be there. Now after great thought how do you keep the columns straight in a multi column pk? So if table1 has a primary key of a,b,c and the foregin key in the table2 is e,f,g and then to find the key a=g,b=f and c=e how do you specify this now? There is no guarantee on the order the fields are pulled out of the primary key. Is the order we specify them in the cmp-fieldfield-name have to be the same on both sides of the relation?

Re: [JBoss-dev] 1 to Many Relations
Uncle. It seems that JBOSS is designed assuming that it has full control of creating tables. Well in my case I already have a database allready set up so my view of things is how do I stuff this database into JBOSS. I don't think it is worth the discussion which approach is right or wrong but, we should document the view jboss takes and then write appropriate documention for the other approach. Dain if you could get at DTD for jbosscmp-jdbc.xml I'll tidy up xdoclet and write some documentation for I've got these tables now how do I do relations in JBOSS. This should eliminate this thread occurring over and over on the user mailing lists. Dave Dain Sundstrom wrote: If I use the jbosscmp-jdbc.xml file I can get it to work. Do you have to use the jbosscmp-jdbc.xml file? If you don't, what happens? Does the system generate two columns with the same name? The database table already exsists. Basically I have to use foreign-key-fields and set field-name and column-name attributes the same. Ok, now we are getting somewhere. If you want to use an existing database structure you must tell JBossCMP about it. JAWS had the same requirement. If your database happens to work by default, well you were lucky. We make no gaurentees that JBossCMP will map by default the way you want. We may decide that a default name was stupid and change it. Let make this very very very very clear. All column names are either generated, or specified in the jbosscmp-jdbc.xml file. All column names are either generated, or specified in the jbosscmp-jdbc.xml file. Your opinion is that when jboss generates the column name for a relationship fk it should first attempt to the name of the cmr-field abstract accessors. Problems occur when the entity does not have an accessor for the relationship, and when the primary key related entity maps to more then one db column. What is your complete proposal for fk column generation and relation-table column generation? Be specific. Not quite I suggest you use the name of the cmr-field-name in the ejb-relationship. therefore when creating the column the field always has to be there. What about many-to-one unidirectiona relationships that wish to use a fk? Now after great thought how do you keep the columns straight in a multi column pk? So if table1 has a primary key of a,b,c and the foregin key in the table2 is e,f,g and then to find the key a=g,b=f and c=e how do you specify this now? There is no guarantee on the order the fields are pulled out of the primary key. Is the order we specify them in the cmp-fieldfield-name have to be the same on both sides of the relation? Once you answer this I can pull the rest of the proposal together. Order has nothing to do with this. Each pk field is mapped by name in the foreign-key-fields element or the table-fields element. foreign-key-fields foreign-key-field field-namea/field-name column-namee/column-name /foreign-key-field foreign-key-field field-nameb/field-name column-namef/column-name /foreign-key-field foreign-key-field field-namec/field-name column-nameg/column-name /foreign-key-field /foreign-key-fields All of this information is mainatined in the field objects (see the bridge package). -dain ___ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development ___ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development

Weird. So this has to point to either the standardjbosscmp-jdbc.xml or jbosscmp-jdbc.xml. What's really strange is the default is null. This should come from standardjbosscmp-jdbc.xml.

Re: [JBoss-dev] Securing JNDI http invoker.
Ok. We got it to work but we had to call
new org.jboss.invocation.http.interfaces.Util();
after we logged in and before new did new InitialContext().
I think the test case works becuase it tests the failure first, which
would call the static part of Util to initalize the context, so when the
actual valid call is done the static method has been called.
Now do I have to hard code the http invokers into the jboss.xml
deployment file for each bean? Why does the naming lookup not update the
invocation context with the http invoker on the home methods and then
the home methods update the EJB clases with the home's invoker type?
I need both http invocation and rmi based on how the bean was looked up
in JNDI.

Re: [JBoss-dev] AOP versioned ACID objects 1st iteration
Too bad that the whole world is more intretsed whether or not JBOSS will become J2EE certified. I was reading an article about Unintended Consequences that made me think of the current J2EE cerification vs. JBOSS 4.0 with AOP. In 1349 the black plague was spreading around Europe. In castles and universities and town halls across Europe, great minds pondered the cause of the plague. And they came pretty close. The collective academic wisdom was that the source of the Black Plague was fleas. So the word went out from town to town across Europe - to stop the plague - kill the fleas - by killing all the dogs. And immediately the slaughter of all dogs began. But like lots of well-intentioned academic ideas it was somewhat wide of the mark...and had unexpected consequences. The cause was fleas all right, but not dog fleas...it was rat fleas. And in the 1300's what was the most effective way to hold down the rat population? You guessed it - dogs. So by suggesting that townsfolk kill their dogs, the wise authorities had unwittingly allowed the rat population to flourish and thus a new vicious rash of Black Plague began. Before it was over, three years later, nearly 1 out of 3 people in the world had died of the plague.

You can transactionally version an object. If you modify the object within a transaction, this modification is not seen by other transactions. If the tx commits, the changes seen, if a rollback happens the changes are rolled back. On commit, if another tx has modified the object, the tx will rollback (OptimisticLocking). The way it works is as follows: POJO pojo = new POJO(); pojo = (POJO)org.jboss.aop.plugins.Versioned.makeVersioned(pojo); calling Versioned.makeVersioned creates a proxy that sits in front of the real object. transactionManager.begin(); pojo.callMethod(); when callMethod is invoked since there is a transaction, an interceptor creates a copy of the REAL pojo and does all further invocations on this copy. pojo.someField = 5; If you have field interception turned on, public field will also be accessed via the copy/version tm.commit(); On commit, a tx Synchronization checks to see if the version you have created is the latest and greatest. If not an org.jboss.aop.plugins.OptimisticLockFailure exception is thrown in beforeCompletion. I'm not sure how this exception is wrapped. Some other semantics: 1. All method invocations force a version to be created. You can avoid this by declared class-metadata as follows: class-metadata name=234234 group=VERSIONED class=org.jboss.test.aop.bean.VersionedPOJO method name=get.* read-onlytrue/read-only /method /class-metadata A readonly method will not cause the creation of a version and the current object will be used. An example and unit test is under testsuite/src/main/org/jboss/test/aop/bean/VersionedObjectTester.java The example object VersionedPOJO.java, has 1 interceptor pointcut declared on the class to do Tx stuff. See testsuite/src/resources/aop/META-INF/jboss-aop.xml for more details. What would be nice is to also write a TransactionalLock interceptor for versioned POJO's that have high OptimisticLock failures.

Hi,
so I dug into the hotspot code for JDK 131, and I found the problem. I am too tired
now to think for a solution, this is for you brave guys :)
The problems arises from a 20 lines of code in
src/share/vm/memory/systemDictionary.cpp (attached), method
resolve_instance_class_or_null(...).
The loading mechanism of the JVM is done in 2 steps:
1- look in a dictionary, if not found, put there a placeholder, then
2- load the class, calling loadClassInternal().
Thread A comes in asking for class cls1 with classloader cl1, the class has never
been loaded, put a placeholder in the dictionary, and call loadClassInternal.
Thread B comes in asking for class cls1 with classloader cl1, there is already a
placeholder, throw CCE.
The key is to ask for the same class with the same classloader.
I think this may happen with the UnifiedClassLoader scheme in several occasions, a
simple example being:
class Base {}
class Derived1 extends Base {}
class Derived2 extends Base {}
If Base is loaded by classloader1, and we have 2 threads trying to load one Derived1
and one Derived2 (and both need Base), we end up with 2 thread using the same
classloader to load the same class, and the JVM code throws CCE.
I wrote a simple testcase (attached), but it does not use JBoss classloaders,
however should be trivial to code it against JBoss codebase. If someone can take care
of it... thanks :P
As I said I did not think enough to find a solution, but at least we all know where
to start.
Cheers
Simon

RE: [JBoss-dev] ClassCircularityError - PROBLEM FOUND !
Actully does not this part of the JVM spec basically say it all ... 5.3.2 Loading Using a User-defined Class Loader The following steps are used to load and thereby create the nonarray class or interface C denoted by N using a user-defined class loader L. First, the Java virtual machine determines whether L has already been recorded as an initiating loader of a class or interface denoted by N. If so, this class or interface is C, and no class creation is necessary. Otherwise the Java virtual machine invokes loadClass(N ) on L.1 The value returned by the invocation is the created class or interface C. The Java virtual machine then records that L is an initiating loader of C (§5.3.4). The remainder of this section describes this process in more detail. When the loadClass method of the class loader L is invoked with the name N of a class or interface C to be loaded, L must perform one of the following two operations in order to load C : 1. The class loader L can create an array of bytes representing C as the bytes of a ClassFile structure (§4.1); it then must invoke the method defineClass of class ClassLoader. Invoking defineClass causes the Java virtual machine to derive a class or interface denoted by N using L from the array of bytes using the algorithm found in Section 5.3.5. 2. The class loader L can delegate the loading of C to some other class loader L'. This is accomplished by passing the argument N directly or indirectly to an invocation of a method on L' (typically the loadClass method).

Ok, can you do one more test ?
Can you please print the classloader for your classes, via for example:
com.candata.gateway.EncryptionService.class.getClassLoader()
and for the lib classes, via for example:
com.entrust.toolkit.User.class.getClassLoader()
com.entrust.toolkit.credentials.Profile.class.getClassLoader()
I think Class.forName may be the source of the problem, as bypasses a direct call to
the classloader, going directly to the JVM class cache.

The -sevice.xml file that starts this is has them in a classpath def
pointing to the current directory. Where it is dieing it is simply
reading a file that has the x509 certificate info.
Ok, can you do one more test ?
Can you please print the classloader for your classes, via for example:
com.candata.gateway.EncryptionService.class.getClassLoader()
and for the lib classes, via for example:
com.entrust.toolkit.User.class.getClassLoader()
com.entrust.toolkit.credentials.Profile.class.getClassLoader()
I think Class.forName may be the source of the problem, as bypasses a direct call
to the classloader, going directly to the JVM class cache.

[JBoss-dev] JBoss through firwall - RMI -HTTP tunneling
Now I have my swing client running with a jboss backend I would like to move this beast out on to the internet.

Re: [JBoss-dev] JBOSS CMP - relations not using DefaultDS
Sorry.. I was trying give the solution the same time as the problem. My problem is if you are using foreign-key-mapping with two tables that are not in the default datasource the relation tries to execute the sql command on the default datasource. For table mapping you can specify the datasource for the relation table. For foreign-key-mapping we should use the datasource of the table not the default. So.. table a and b in datasource LocalDb. The default datasource is RemoteDb. a has a 1 to many unidirection relationship with b. When you are trying to access the collection it is looking for b in thew RemoteDb instead of the LocalDb.

RE: [JBoss-dev] http transport
The HTTP RMI tunning is the shits. Firstly there is no option to go with https without getting really ugly. Secondly, the whole cgi-script or servlet which then calls the local rmi listener generates two network calls for lookup. Since jetty is running in the container the servlet lookup should be a local JNDI lookup.

RE: [JBoss-dev] http transport
Snip ... You mean no url provider, but jndi.properties (=environment)? OK. But I can't live with global jndi.properties. I need them on a per *-ref basis, because the components I connect are spreaded across several different application servers. It would seem that you would still want a global JNDI directory with 1 point of entry. This could be a JNDI mbean that does nothing else than sit infront of all of your other application servers and keeps references to all the other beans in the other applcation severs JNDI directories. When a request came in it could lookup the actual reference, wrap in up in a proxy and hand it back. The proxy would then know which application server it would talk to. I think hard coding aliases into *-refs is a bad idea. It would be a maintence nightmare. A global lookup location would be way easier. So your jndi.properties would only have to get you to the global JNDI directory at boot time. These properties could change based on each client logging in and loading a profile.

Now I can hack around this but it does not make sense to have dependencies if you have to hack around them. A quick peek at the code shows the create method is being called and then the create method in the service control checks to see if the mbean has dependices and should be created/started. This seems backward. Should we not first check to see the dependices are met and if they are not simply register the name and do not try to instaniate the class. --- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ___ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development

[JBoss-dev] Bug in relations
I was testing the current state of the relation code and I believe I have stumbled across a bug. If the primary key class of relationship is different then it bombs. So if you have table_a and table_b in a 1-1 uni-directional relationship with table_a primary key class of TableAPk and table_b primary key class TableBPk it bombs. It looks like the problem is in JDBCCMRFieldBridge.java around line 780. When it is creating and setting the primary key of the CMRField. fk = foreignKeyFields[i].setPrimaryKeyValue(fk, fieldValue); The problem is that if fk is null it creates a Pk class but in foreignKeyFields the entity is current class not the related one. So for TableA CMR field is is creating a class of TableAPk not TableBPk. I added the this before the call and it seems to work if(fk == null) fk=relatedManager.getEntityBridge().createPrimaryKeyInstance(); ___ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development

Everything seems to work fine when JBoss is checked out as a whole. However, when I check out the 'jboss-mq' module from CVS anonymously, build it, and then run the server it doesn't deploy! No TCP/IP ports (or UDP/IP for that matter) are opened. So there's no endpoints for RMI to provide access to JNDI or the messaging transports.

[JBoss-dev] More relationship stuff
I've pulled the latest jboss head and I am testing a 1-1 uni directional
relationship. The database tables are already created. So I have
create table test_cust (
test_cust_id int PRIMARY KEY,
billing_address_id int
);
create table test_address (
test_address_id int PRIMARY KEY,
an_address varchar(50)
);
So TestCust ..
TestCust {
AddressLocal getAddress();
void setAddress(AddressLocal l);
}
jbosscmp-jdbc.xml
sniped ..
ejb-relation
ejb-relation-nameUni_1_to_1/ejb-relation-name
foreign-key-mapping
ejb-relationship-role
ejb-relationship-role-nameCust_has_an_address/ejb-relationship-role-name
fk-constrainttrue/fk-constraint
foreign-key-fields
foreign-key-field

ejb-relationship-role
ejb-relationship-role-nameAddr_has_no_idea_of_TestCust/ejb-relationship-role-name
/ejb-relationship-role
/foreign-key-mapping
/ejb-relation
So everything looks cool until it tries to add the address
INSERT INTO test_address (test_address_id, an_address, TestCust_address)
VALUES (?, ?, ?)
It looks like jboss is throwing in a CMR field even though it is only a
1-1 uni directional relationship.
Bug?

[JBoss-dev] JAAS with MDB
I am trying to get a MDB working with JAAS. Currently when message
delivery is attempted it throws an error Authentication exception,
principal=null. Now in the jms-service.xml I have added
attribute name=PrincipalMappingProperties
UserName=jboss
Password=jboss1
/attribute
but this does not do anything. I can not find any refences to this in
either the free or purchased docs. Can some one point me in the right
direction.
time passes ...
After further investigation it looks like it is not implemented. In the
JMSContainerInvoker it creates the method invocation with principal and
credential = null. Then when the SecurityInterceptor gets a hold of it
barfs. The snip, line 976 of JMSContainerInvoker.java
invoker.invoke(id,
// Object id - where used?
ON_MESSAGE,
// Method to invoke
new Object[]{message},
// argument
tm.getTransaction(),
// Transaction
null,
// Principal
null);
// Cred
How should I go about getting this to work?

Re: [JBoss-dev] JAAS with MDB
It actually goes a little furthur than that. I first tried to take out
the security interceptor in the MDB interceptior chain. This works fine
util your message bean then tries to call another EJB. So it would seem
that the Security Interceptor needs to just act as a login for the MDB.
Scott M Stark wrote:
MDBs need a different SecurityInterceptor that does not attempt
to authenticate the caller as there is none defined. An extension

The properties could be specified in the jboss.xml descriptor in
the message-driven bean section.

Re: [JBoss-dev] JAAS with MDB
So then in JMSContainerInvoker add the code to read the jboss metadata and then invoke the inteceptor chain with the appropreate princpal and credidentals? Or should the JMS message actually set properties in the message itself and a new Security Invoker to read this info and set the principal and credidents.

Re: [JBoss-dev] JAAS with MDB
OK. So I had a quick peek at the SpyMessage and there is a field called producerClientId that should do the trick. So I add an interceptor in front of the security interceptor that takes the first argument of the invoke , casts to a SpyMessage, grabs the id and sets the Principal in the method invocation and continues along the chain. Will the only type of message delivered to the invoker be a SpyMessage? or can it handle other messages that could cause a class cast error? Scott M Stark wrote: Authentication and Authorization need to be two seperate security interceptors. Authentication needs to validate the principal and associate the Subject with the MethodInvocation. The Authorization interceptor will handle role based permissions and run-as identities. The default MDB interceptor chain should not include an Authentication interceptor. If the jboss.xml metadata is enchanced to allow for caller identity to be obtained from the JMS msg than the container invoker will associate this information with the call and the Authentication interceptor can be added to the interceptor chain.

Re: [JBoss-dev] JAAS with MDB
Glad to see someone else is reading this thread. After some more hacking we should come up with new login and password tags. The current mdb tags require that each MDB that needs a durable subscription has to have a unique user name and password. For the case of security this is overkill and most likely these beans will be run under one common alias login. (Same way that the jboss server runs under the user jboss but no one can login as jboss) How about .. mdb-authentication-user mdb-authentication-password Mike Swainston-Rainford wrote: Hi Scott I found these during my code read through and investigation of current jboss.xml elements. mdb-user, mdb-passwd and mdb-client-id and mdb-subscriptin-id are all loaded in MessageDrivenMetaData.

Re: [JBoss-dev] message selectors
Go nuts. I have only used bison and flex and I have some pressing other
stuff to do now. The current problem with the message selectors is that
text is returned with the ' . So app_id='my app' turns into
EQUAL(
Start Identifier@app_id
Start 'my app'
Now it looks like the STRING token should not return the '
| STRING:
'
( (~[',\n,\r])
| ('')
)*
'
Go ahead and make the stuff case insensitive.

According to the JMS spec the reserved words are case insensitive. A
part of the TOKEN spec I use in the new EJB-QL parser follows:
TOKEN [IGNORE_CASE] : /* RESERVED WORDS */
{
FALSE: FALSE
| NOT: NOT
| NULL: NULL
| TRUE: TRUE
}
The boolean declaration won't work because you have the same regular
expression in two sections. Remember that token is part of the lexing
step where the input stream is broken into logical token. Then the
syntax part happens. If you need a production later in the grammar
which can be true or false, you would add the following bnf_prduction:
void Boolean() :
{}
{
(TRUE | FALSE)
}
I'm by no means a JavaCC expert (I'm still learning it my self), but if
you want, I'll look over your jj file when you finish.

OK. it looks like it does not like the BOOLEAN token as a combo fo the
TRUE and FALSE tokens. Inlining them works. Patch inclosed.
Now the selector will parse but still does not deliver it properly.
Going to bed , have a look in the morning...

Ok. First problem solved. We have to call the SelectorParser
constructor with at least a string reader. The problem is when you go
to run ReInit with the actual selector it throws a NPE. So in
SelectorParser.jj add the following to the no-args constructor
this(new StringReader());
Boolean slector still does not work ... looking

Can you please verify that things are still broken with the latest CVS
(with the changes I just commited). Please submit a testcase, if you
are in there and finding problems just throw something together and
submit it.

Actually it's worse than that. If you change the default parser to
SelectorParser, nothing works! So a simple slector like
type='cadex' bombs.

I did not think we were using the old parser anymore... Is there a
reason this is still around after Scott reimplemented in JavaCC?

After having a bad day trying to get a message selector working
for a topic listener I came across a few bugs.
1) If the message selector is invalid but the connection is not
started but no error is thrown. So if you createTopicSession
then createSubscriber and then start the connection the
connection looks good but there are no messages delivered. (I
spent most of the day trying to sort this one out)
2) The message selectors do not seem to like boolean types. My
query is
app_id='AK' and production=TRUE
3) What parser are we using for the message selectors. I thought
we were using javacc and jms.jj. But in Selector the default is
set to parser which is from jms.y. I don't even think this thing
is getting re-processed. I did swicth the default to
SelectorParser but that did not work as well.
