Problem with Template example: invalid ejb-name

[jiuyang]

Hi,

I am using Jboss 3.2 with ANT 1.5.3-1, Xdoclet 1.1.2, and jdk1.3.1_02 on Win2K. I tried to deploy the template by following the exact steps in the Getting Started document, but encountered a problem.

I created a build.properties, and changed the build.xml to point to this file. When I run 'ant main', jboss reported this error: "Error in ejb-jar.xml for Entity Bean test/TestEntity: The ejb-name for a CMP2.x Entity must be a valid Java Identifier"

How to resolve this error? Thanks in advance.

Ok I found a reference on how to solve this problem in a previous thread - http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t=

I am having the same problem you had. I followed the instructions in the other link and now I get the following, do you have any suggestions:

Hi,

Did you change yr ejb-name xdoclet declaration to @ejb:bean name="TestEntity" in yr bean code?

I have the same problem. When I run ant main:

I got the following:

Anyone can help with this

Thanks!

I have this problem also. I foillowed the instructions in the other thread and got:

Anybody got past this point ????

[smile]

Change the @ejb:bean name="test/TestSession" tag in TestSessionBean.java into @ejb:bean name = "TestSession".
This change is not stated in the other thread.....

[mdoherty]

Thanks for the suggestion but unfortunatly it did'nt work. Still get the same output as above.

Does anybody know what this error is telling us - why does it think this EJB is not defined and what stage of the xdoclet build process is this happening at ?

[jandrews]

I have implemented the changes in the reference message, and I'm still getting an error. Just to reiterate for users in this group (organized by file):

TestEntityBean.java:

a. remove "test/" from @ejb:bean everywhere it appears
b. remove "test/" from @ejb:ejb-ref
c. drop "@jboss:finder-query
d. add @jboss:finder name="findByName" query="SELECT OBJECT(t) FROM TestEntity t WHERE t.firstName = ?1 AND t.lastName = ?2"
e. add @jboss:finder name="findAnotherByName query="SELECT OBJECT(t) FROM TestEntity t WHERE t.id ?1 AND t.firstName = ?2 AND t.lastName = ?3"

SequenceGenerator.java:

a. remove "test/" from @ejb:bean wherever it shows up.

TestSessionBean.java:

a. remove "test/" from @ejb:ejb-rev ejb-name.

I'm now building successfully, but when I deploy, the jboss log gives me the following:

16:24:23,007 WARN [verifier] EJB spec violation:

Anybody have a clue here?

I had the same problem, because I misunderstood the advice about adding the @ejb:finder directives to TestEntityBean.java. Fortunately, someone had posted the correct source on another thread.

Make sure the @ejb:finder directives in the TestEntityBean.java file look like:

* @ejb:finder signature="java.util.Collection findAll()"
*
* @ejb:finder signature="test.interfaces.TestEntity findByName( java.lang.String pSurname, java.lang.String pLastName )"
* query="SELECT OBJECT(t) FROM TestEntity t WHERE t.firstName = ?1 AND t.lastName = ?2"
*
*
* @ejb:finder signature="test.interfaces.TestEntity findAnotherByName( int pId, java.lang.String pSurname, java.lang.String pLastName )"
* query="SELECT OBJECT(t) FROM TestEntity t WHERE t.id <> ?1 AND t.firstName = ?2 AND t.lastName = ?3"
Note that these are @ejb:finder directives, not @jboss:finder directives (though I'm not sure it makes a difference)

This should get you past the deployment error. However, you should also put the 'test/' string back into the directives in TestSession.java, otherwise the test client won't be able to find it via JNDI.

Best of luck!

BTW, the thread that led me to the solution is at

<http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t= in particular user hansbaus's post of Dec 18, 2002, which has an attached Java file.

[macamat]

Just wanted to say thanks for the great help in this post and others dealing with the example project. Getting it working on 3.2.1 is not easy for a newbie to JBoss but I just got there - it is possible!

[artmotion]

Good for you.
Could you put it somewhere online, so that other 3.2.1 newbees can start mor easily?

Or send it me, I put it onlin!
