WebLogic.ejbc vs weblogic.rmic

See examples/iiop/ejb/stateless/cppclient for an example of how to get
this to work. You have to jump through hoops with VisiBroker.
I have deployed a stateless EJB in WLS6.1sp1 / NT and I am trying to write a CPP
Visibroker 4.5 client to acces it...
The steps i took:
While doing the ejbc i have given the option -idl by using
java weblogic.ejbc -iiop -idl -idlDirectory d:\idls -idlVerbose -compiler javac
d:\lib\my.jar -d d:\testjava\my.jar
This file generates two IDL files xHome.idl and x.idl, x.idl contains the business method
of my bean
and xHome contains the ejbCreate method...
According to documentation i can use weblogic.rmic to get these same idls however when i
run
java weblogic.rmic -idl -idlVerbose -idlDirectory .\idls xBean
It creates an idl which has no business method in it but has all private variables
defined in my bean....
I am confused which idl file i should be using....??? as i understand if there is no
business method in IDL my client can't call those methods on EJB..The first two are the right ones.
I thought of going another step and try using both the idls one by one and see but
while compiling the idl by command
idl2cpp -I . -namespace -gen_included_files -root_dir .\corba x.idl
i get
idl2cpp: (warning)::CORBA::Environment declared ("orb.idl", line 28) but never defined
idl2cpp: (warning)(references to it will be permitted, but no code will be generated for
this definition)
idl2cpp:IDL native type ::CORBA::AbstractBase has no known translation; generated code
will not be valid
******************This is a VisiBroker bug - but I think you can safely ignore them.
The orb.idl i am using is from VisibrokerFor C++ 4.5
i tried compiling the orb.idl alone but got the same things..
has anyone else seen this behaviour or i am doing smthg wrong.???andy

Weblogic.ejbc wants weblogic.home sysproperty in ant - why

I found that I had to add the following 'sysproperty' line to an ant target which
runs weblogic.ejbc:
<target name="ejbjar" depends="jar">
<mkdir dir="${java.class.dir}/${package.dir}/tmp"/>
<java classname="weblogic.ejbc" fork="true" failonerror="true">
<sysproperty key="weblogic.home" value="c:/bea70/weblogic700/server"/>
<classpath>
<path refid="classpathWL"/>
</classpath>
<arg line="${java.class.dir}/${archive}.jar ${java.class.dir}/ejb-${archive}.jar"/>
</java>
</target>
If the line is not there I get an error:
[java] ERROR: Error from ejbc: error in finding weblogic.Home
If the line is there and points to an invalid weblogic.home directory the error is:
[java] ERROR: Error from ejbc: Installation file c:\temp\lib\persistence\persistence.install
does not exist. Could not initialize EJB container managed persistence.
However the file contains only one line:
WebLogic_CMP_RDBMS.xml.
Question: is there a way to specify this value directly to weblogic.ejbc without
the look-up to the file? In my case I would like to do a build on a machine where
weblogic is not installed (but of course weblogic.jar is available). It is trivial
to add the file to the FS somewhere but why bother?

here is my Ant target looks like...
<property name="classpath" value="${lib.ext.dir}/j2ee12.jar;${lib.ext.dir}/weblogic.jar;${lib.ext.dir}/log4j-1.2.9.jar;${lib.ext.dir}/struts.jar;${dest.dir}/${ant.project.name}.jar"/>
<target name="testjar">
<javac srcdir="${src.dir}" destdir="${ejbc.dir}" classpath="${classpath}"/>
<ejbjar srcdir="${dest.dir}" descriptordir="${desc.dir}" basejarname="test" classpath="${classpath}">
<weblogic destdir="${lib.dir}" classpath="${classpath}" oldCMP="false"/>
<include name="**/ejb-jar.xml" />
<exclude name="**/weblogic*.xml" />
<dtd publicid="-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" location="${lib.dir}/dtd/ejb20-jar.dtd"/>
<dtd publicid="-//BEA Systems, Inc.//DTD WebLogic 6.0.0 EJB//EN" location="${lib.dir}/dtd/weblogic-ejb-jar.dtd"/>
</ejbjar>
</target>
I a not sure where to specify <sysproperty....>
Please revert back if u know the answer.

Auto deploy, weblogic.ejbc, -iiop automatically?

Hi;
I am using WLS 6.1sp2 and I don't like to run weblogic.ejbc manually. I
let the server do it when I deploy when EAR file. Is there a way to make
the server specify the "-iiop" option when the server automatically runs
ejbc?
Paul Rowe

I guess that's what 'ExtraRmicOptions' property in the ServerConfig is for:
Returns the extra options passed to rmic during server-side generation.
in the console it is in the Server -> ... -> compilers tab.
(or it can be set per-EJB: Return the extra options passed to rmic during
server-side generation. Note: the default for this attribute must be null.
If no ExtraRmicOptions are specified on the EJBComponent, the default will
be pulled from Server.ExtraRmicOptions).

If you can have a look at a cmp example in the samples that ship with the server. My guess is that the weblogic-ejb-jar.xml file is missing the <persistence-use> element which for 810 would look like:
<persistence>
<persistence-use>
<type-identifier>WebLogic_CMP_RDBMS</type-identifier>
<type-version>7.0</type-version>
<type-storage>META-INF/weblogic-cmp-rdbms-jar.xml</type-storage>
</persistence-use>
</persistence>
I seem to recall that the elements might be slightly different in structure for the wls700 version of the DTD, so please check that (I cannot, I'm at home and don't have everything here).
Give that a try and see if it doesn't solve your compilation failure.
Also, the compilation should not be throwing a null pointer exception in a case like that, I consider that to be a bug.

Weblogic.ejbc compiler

Hi, i've a problem with the boot of the entity beans.
My entity beans extends a class in which there is a definition of a public variable Long which there isn't defined in the bean but it is in the ejb-jar.xml as cmp-field and in the weblogic-ejb-extensions as attribute map.
The weblogic.ejbc -i ejb-jar.xml -x weblogic-ejb-extensions.xml doesn't give me exception, but when i boot the application (tmboot -y) i've this log :
ERROR: While deploying bean it.sella.anagrafe.evento.EventoEJB
java.lang.NoSuchFieldException: id
174943.dcsv01!JavaServer.7981: main: EJB_CAT:28: ERROR: While deploying bean it.sella.anagrafe.evento.EventoEJB
: The EJB Container received weblogic.ejb.common.DeploymentException: EJB_CAT:28: ERROR: While deploying bean
it.sella.anagrafe.evento.EventoEJB :

Could you help me?

Error 28 indicates that there is a problem with the deployment descriptor. Check that -- ERROR 28: Make sure the deployable JAR contains a compliant deployment descriptor.
There are following the two xml files, The EventoBean class, the EntityBeanAdapter class extended by EventoBean and the primary key class DefaultPK
This is, i think,the better way to an help.
The problem is in the boot of the application( the same works fine with WLS5.1)

Confused about the role of ejbc in Weblogic 7

Howdy All
Here is my understanding of the role of ejbc in Weblogic 7:
* Let's assume I have a JAR containing an EJB (let's say a stateless session bean).
Let's call this the no-ejbc-JAR.
1. I run the no-ejbc-JAR through ejbc to create the container-ejbc-JAR which can
now be deployed in Weblogic.
2. I can run ejbc against the no-ejbc-JAR to create a client-ejbc-JAR for use
by clients wishing to access and use the EJB.
Questions...
MUST I run the no-ejbc-JAR through ejbc (to create the container-ejbc-JAR) before
it can be deployed in Weblogic 7?
If so, why?
I can sort of see why this may be necessary from the containers perspective, although
I would have thought the ejbc process could have been automatically applied by
Weblogic to no-ejbc-JARs being deployed.
But I am confused as to why ejbc would need to be used to create a client-ejbc-JAR.
From the client's perspective, isn't it simply enough to have the no-ejbc-JAR
(or a subset of the no-ejb-JAR) containing the EJB home and remote interfaces
(along with any non-ejbc generated support classes)? For use by the client, why
would it be necessary to run the no-ejbc-JAR through ejbc to create a client-ejbc-JAR?
Or do I have an incorrect understanding of the role of ejbc?
Thanks,
Rob

Hello Rob,
I will try to clarify a couple of your concerns. First of all, if your EJB jar
contains CMP 2.0 entity beans, the underlying JDBC implementations must be generated
for your respective abstract classes of the entity beans. EJBC will generate this
for you automatically. Also, the EJBC utility generates all of the other necessary
server classes that WebLogic requires for deploying your EJBs (such as custom
code for handling transactions, security, and other EJB services). When your EJB
utilizes remote home/component interfaces, the utility will also generate all
of the necessary client-side proxy and server-side byte code by running the RMI
compiler on your EJBs. In addition to the above code generation that takes place,
EJBC also checks all of your EJBs and makes sure that they are written according
to the EJB specification. This way you will always be sure that your EJBs will
be deployable on BEA WebLogic if EJBC returns with no error messages. You also
asked if EJBC must be run manually before deploying the EJBs. If you run your
application in exploded directory format, WebLogic will automatically invoke the
EJBC utility prior to deploying your EJBs. Please refer to the links below for
more information about the EJBC utility as well as deploying your application
in exploded directory format:
http://edocs.bea.com/wls/docs70/ejb/EJB_utilities.html#1075296
http://edocs.bea.com/wls/docs70/programming/deploying.html#1125152
Also, feel free to examine the code that EJBC generates to gain a better feel
for what's happening behind the scenes. Also, please be aware that ejbc has been
deprecated in WebLogic 8.1, in favor of the appc utility:
http://edocs.bea.com/wls/docs81/ejb/EJB_tools.html#1096936

The code generated by EJBC in Weblogic 5.1 is wrong!

I have a container managed bean that has a primary key named
productLicenseId as follows:
public class ProductLicenseBean implements EntityBean
public int productLicenseId;
I had this code running in Weblogic 4.5.1 and converted it to EJB 1.1
(now I use java.lang.Integer for the primary key class) and attempted to
build it using WebLogic 5.1. I built your container managed example
(AccountBean), which built fine (it is clear why your example did not
have the problem mine did- the primary key is java.lang.String). After
that, I tried to build my container managed bean, but without success.
Here is a description of my problem:
After trying to compile my simple container-managed program using EJBC
in Weblogic 5.1, I get the following error:
ProductLicenseBeanEOImpl.java:56: Incompatible type for =. Can't convert
int to java.lang.Integer
pk = bean.productLicenseId;
ProductLicenseBeanEOImpl.java is a class that was generated by EJBC. It
is clear that this code is incorrect! The generated code (pk =
bean.productLicenseId) attempts to assign the primary key in the
ProductLicenseBean (an int) to a java.lang.Integer (pk is of type
java.lang.Integer), which is wrong! The source code generated by EJBC is
wrong!
Do you have a bug fix for this, or is there something I'm just not
getting?? !!
I should be able to use a java.lang.Integer as a primary key.
Thanks much for your help.

I had the same problem. I had used the deployer tool and had specified a
primary key class AND a primary key field "ID".
This had put an extra tag in the ejb-jar.xml file <persistence field> which
I hadn't seen before.
Changing the primary key field to "none" fixed caused other problems to show
up in the deployer tool (finders). I had to redo the
deployer project from scratch, this time keeping the primary key field to
"none" and it worked.

Urgent pls ! Error during Container code generation using weblogic.ejbc

HI all,
Iam using weblogic6.1 and EJB 2.0. I have to communicate session and entity ejb's and iam using local interfaces for entity beans and access the entity beans thru session ejb's. After creating my programs and jar files, when i use java weblogic.ejbc code.jar Containercode.jar, i get the following error....
--------- Error -------------
C:\Sathish\Ejb\wl6.1\LocalInterfaces\Code\ejbcgen\CodeBean_tvm2r0_ELOImpl.java:34
0: cannot resolve symbol
symbol : constructor EJBException (java.lang.String,java.lang.Exception)
location: class javax.ejb.EJBException
throw new javax.ejb.EJBException("Unexpected exception in " +
^
1 errors
Exec failed .. exiting
Can anyone say why this error is occuring......
regards
sathish

In J2EE 1.3, EJBException added a third constructor of the form:
EJBException(java.lang.String, java.lang.Exception)
WebLogic contains a file called j2ee12.jar in the lib directory that when placed in front of the classpath, disables J2EE 1.3 features and replaces them with J2EE 1.2. In J2EE 1.2 this constructor did not exist.
So in order to compile using J2EE 1.3 features, you must make sure that j2ee12.jar is not in your classpath.

Usage of weblogic.ejbc

Hi Guys,
Well i am trying to use weblogic.ejbc to generate the ejb container specific code and create a new jar file which i can deploy.
But this command is throwing the following error shown below
The jar file contains the ejb class files and the 2 xml files [ejb-jar.xml and weblogic-ejb-jar.xml].
ERROR: ejb-jar file: /opt/.../frbom.jar could not be opened
Could anyone please let me know the possible reason for this error....
Thanking you
regards
richi
.

Hey,
Thanks for the immediate reply
I used the weblogic.ejbc command on a jar file containing my ejb classes[home,remote,bean],other classes and the required descriptors[ejb-jar.xml,weblogic-ejb-jar.xml]
to be precise i used the following command
prompt> java weblogic.ejbc /opt/.../frbom.jar output.jar
but this is throwing me an error
ERROR: ejb-jar file: /opt/.../frbom.jar could not be opened
What could be the possible reason??
Thank you
Regards
Richi

Error running weblogic.ejbc with Toplink 10G

I'm making some tests in order to move to Weblogic 8.1 and Toplink 10g in the near future, but I'm having some problems with my tests:

This is the part of the XML that I think causes the problem:

</toplink:call>
<toplink:reference-class>test.data.MessgeBean</toplink:reference-class>
<toplink:cache-usage>conform</toplink:cache-usage>
</opm:query>
Of course I don't see any problem with it.
After that I tried to run the examples but I'm seing the same error.
I must say that I'm not using the ANT scripts but doing it "by hand" building classes and making the naked jar for the bean in order to run ejbc on it, I'm pretty confident I am not missing anything.
I would like to know where the "ejbql-call" definition is as I have tried to find it with a grep in all the Toplink structure tree with no success. It is not clear to me how the xsd processor would find it's definition with just the: xmlns:toplink="http://xmlns.oracle.com/ias/xsds/toplink" instruction present in the header of my Message.xml file (modified based on the Account.xml of the examples).
I'm using Sun's JDK 1.4.2 and my $CLASSPATH is:
/opt/oracle/toplink10g/toplink/jlib/toplink.jar:/opt/oracle/toplink10g/lib/xmlparserv2.jar:/opt/oracle/toplink10g/jdbc/lib/classes12.zip:/opt/bea/wlserver8.1sp1/weblogic8.1/server/lib/weblogic.jar
Any idea?
Thanks in advance.

What I don't understand is: if examples include that toplink:ejbql-call it should be declared into the xsd isn't it? It will be included in the future (final) release then?
Thanks again.

C:\VisualCafeEE\Projects\Util\CLASSES;%classpath%;
C:\VisualCafeEE\Projects\JspBO\_JspBO.jar

I put all classes from the C:\VisualCafeEE\Projects\Util\CLASSES in to the
_JspBO.jar then it works fine.

What am I doing wrong? Please help.
[error.txt]

Yes, it works fine with wlfullclient.jar. But I am trying to avoid forcing the user to get a 60MB jar file to run 10 lines of code. Since my other client/ejb works fine with only wlthint3client.jar, I'm trying to figure out what is different with this client/ejb.

Weblogic.ejbc issue in 5.1

Hi,I use weblogic 5.1I tried to generate the server skels and stubs with weblogic.ejbc.its giving me an exception "File not found weblogic.ejb20..."But this package comes with weblogic.jar in 6.0 not in 5.1.Do i miss something in classpath for 5.1Please help me out of this.Thanks,Jegan G Karunakaran

I believe the solution is to ignore the message. It's looks nasty but it is harmless.
Probably got left in the release code by accident. I think SP9 does not print
the message.

What is the proper way to cross link EJB entity beans in 5.1? Ive
tried
every possible combination of (ejb-ref) in the ejb-jar.xml and
(ejb-resource-ref) in weblogic-ejb-jar.xml and when i deploy the beans.
Linked references fail and i get : **** not in archive $$$. It doesnt
crash
however and the beans seem to deploy, but i really want to stabalize
this.
Is there some way to force ONE classloader to deploy all the beans,
or
do i simply need to dump more of these ejb-ref ' s everywhere??
thank you for any assistance.
