[JBoss-user] [Persistence CMP/JBoss] - Re: Mapping Entity Beans to Database Tables
After looking carefully at your traces, I agree with you. The error concerns the findByprimaryKey on your QuestionBean. And the SQL string refers to a question table which is your bean name. The datasource mapping for the QuestionBean is missing, and the datasource and datasource mapping for the QuestionCategorybean is also missing. Try to specify the datasource mapping to PostgreSQL3 OR PostgreSQL 7.2, depends on your version in the jboss.persistence tag I don't understand you don't have a deployment error. With JBoss 3.2.3, I have a deployment error Error in jbosscmp-jdbc.xml : datasource-mapping not found if I do the same thing.

No matter the matching between table names and bean name, or field name and column name, all the mapping is done in jbosscmp-jdbc.xml. I think the problem is the space in your Question Categories.

I don't know which findByPrimaryKey throws an error, but the second one (for QuestionCategory bean) has an error. Your bean abstract schema name is QuestionCategory not QuestionCategorybean. It's surprising you have no errors at deployment. But as says Erik, you can remove both.

I think I got it ! Your primary key class have only one field, and unfortunatly for you, JBoss 3.2.3 is bugged : where the primary key class has only one field, the generated SQL for testing a entity existence before its creation is incomplete (the formet depends for each database : with MSSQL, the WHERE clause is empty). So you have two solutions: 1) Migrate to another version of JBoss (I don't know the one which solve this) 2) As your primary key class contains a single field, you don't need it. Just declare the productID field as the primary key of the bean.

[JBoss-user] [Persistence CMP/JBoss] - Re: adding record to CMR field
As I say to you before, two bad things:
1) Your LectureEntity bean has a cmp field named questions, and a cmr field named also
questions. Remove the tags I indicate before:
| @ejb:persistent-field
| @jboss:column-name name=questions
|
or rename one of them (cmp or cmr) and put the appropriate getter and setter.
2) The QuestionEntity (addQuestion parameter) is a remote interface. You cannot set a
cmr field with a remote interface (only a local). For that, you have two solutions:
2.1 : retrieve a local interface from your client if you can and change your method:
| public void addQuestion(QuestionEntityLocal question) {
| this.getQuestions().add(question);
| }
|
2.2 : if you can't, just pass the primary key and retrieve a local interface in the
method:
Add an ejb-ref to your bean:
| * @ejb.ejb-ref
| * ejb-name=QuestionEntity
| * view-type=local
|
Then in your method:
| public void addQuestion(Long questionId) {
| try {
| javax.naming.Context ic = new InitialContext();
| Object obj = ic.lookup(Your Question bean JNDI name);
| // Something like java:comp/env/ejb/QuestionEntityLocal
| QuestionEntityLocalHome Home =
(QuestionEntityLocalHome)PortableRemoteObject.narrow(obj,QuestionEntityLocalHome.class);
| QuestionEntityLocal question = Home.findByPrimaryKey(questionId);
| this.getQuestions().add(question);
| } catch(Exception e) {
| // Error handling
| }
| }

Even beans are loaded ot not, the collection size is always the total count because the container get the ID's list before loading the beans. If the size is 0, then probably your relationship is not correctly defined. So, post the relevant snippets (descriptors, code) in order to investigate.

No, definitively, I don't see any error in your descriptors. Perhaps the error is a database issue. You are using MySQL 5.0.0A which is not a stable version. Try with the production release 4.0.X. Perhaps the datasource-mapping tag in jbosscmp-jdbc is not set, or the mySQL mapping is not compatible with the 5.0.X version.

You can do what you want with DynamicSQL, which is specific to JBoss. But the J2EE spec do not address your needs.

Hi westmeier, You comfort me because my account also got lost, so I was asking myself if I was running on a third dimension (like in a bad movie but so real ;-). So, You says that you are using the 3.2.4 version. I have seen other recent topics (but some are destroyed now) about the 3.2.4 version problems. Do you try the 3.2.3 version ? I confirm that it works fine with 1000 elements in a collection retreived from a finder usins the XA driver. Normally, the SelectMethod=Cursor is the default if you do not change it in the -ds file. I think also that specifying read-ahead option with a fixed page-size on version 3.2.4 can help, because there is some differences between two versions on this subject. Alex (loubyansky), the JBoss CMP guru says on the previous topic that the version 3.2.3 was bugged for on-find read-ahead option for single object finder. But for both topics, everything works fine with 3.2.3 version, and is ugly or crashes with 3.2.4 version. So, conclude yourself. Iron, the metallic bird from Atlantica.

After a look at your descriptors, We can say that you are not using the XA driver. Try to cut out the | min-pool-size2/min-pool-size | max-pool-size20/max-pool-size | tags. You are already using a read-ahead opion: read-ahead | on-load | page-size1000/page-size | eager-load-group*/eager-load-group | /read-ahead | But why are you using the on-load option ? With the number of beans you are loading, on-find is better I think. You can put also this read-ahead tag within the query tag of your finder if you want using on-find just for the finder.

[JBoss-user] [Persistence CMP/JBoss] - Re: Seeking Clarification (fk constraints)
You are a little bit lazy, but nice and relevant. I read the specs and your understanding is perfectly right. So blame SUN, not JBOSS. My opinion is that the spec is unperfect for relationships and many features are ugly. For example, when you get a collection of child entities with a CMR getter, the container first get all the id's, then retreive all the fields with a WHERE clause like that: (ID=?) OR (ID=?) and so on with all the child Id's. You can imagine with 1000 childs. So, I suggest you a third solution: Do not use relationships. Just get childs with a finder taking the foreign key as parameter, then you can remove them without hurting the database relational integrity. Also, the finder will be faster than the CMR getter.

[JBoss-user] [Persistence CMP/JBoss] - Re: Problem, when
It works fine for me under JBoss 3.2.3 with a collection of 1000 elements (with the MSSQL XA driver). So for me 3 solutions: 1) JDBC XA procedures perhaps not installed 2) CMP engine for JBoss 3.2.4 bugged (other topics in this forum seems to prove that). 3) Use read-ahead with fixed page size to prevent the CMP engine making its own choices.

[JBoss-user] [Persistence CMP/JBoss] - Re: Problem with One to One Unidirectional Relationship
I suggest you to adopt a pragmatic method. Nothing's logical in all this. The first error talks about the getCid() getter, nothing to do with the usertDetails field. So: - Keep a known configuration of your beans and relationships (DO NOT CHANGE BETWEEN POSTS). - Activate CMP plugin traces adding | category name=org.jboss.ejb.plugins | priority value=TRACE class=org.jboss.logging.XLevel/ | /category | in Log4j.xml - Post the server log file content (or the appropriate snippet if too long) - Post your exact descriptors (from your post : what the USER_ID column got to do with relationships ???)

[JBoss-user] [Persistence CMP/JBoss] - Re: Bean not found for relation
It is perfectly defined in the spec and the descriptor schema: | xsd:complexType name=ejb-nameType | xsd:annotation | xsd:documentation | The ejb-nameType specifies an enterprise beans name. It is | used by ejb-name elements. This name is assigned by the | ejb-jar file producer to name the enterprise bean in the | ejb-jar files deployment descriptor. The name must be | unique among the names of the enterprise beans in the same | ejb-jar file.There is no architected relationship between the used | ejb-name in the deployment descriptor and the JNDI name that | the Deployer will assign to the enterprise beans home. | The name for an entity bean must conform to the lexical | rules for an NMTOKEN. | Example: | ejb-nameEmployeeService/ejb-name | /xsd:documentation | /xsd:annotation | For the ejb-name, you can use a path name relative to the referencing ejb-jar file. Appends the ejb-name of the referenced bean to the path name separated by #.

[JBoss-user] [Persistence CMP/JBoss] - Re: curious SQL-Statements when loading related data
Your descriptors are OK, means using default values. Do you try on JBoss 3.2.3 ? I have seen many peculiarities for the ejb plugin on JBoss 3.2.4 series. Perhaps try also to optimize loading. Is your problem occurs after a long run or from the start ?
