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

Hello,
I don't know...but the good folks that monitor the EJB newsgroup [1]
would have a better shot at an answer.

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.

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 :
java.lang.NoSuchFieldException: id while setting container managed persistence.
Could you help me?
Regards

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)

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.

Error running weblogic.ejbc with Toplink 10G

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.
Ignacio.

Weblogic.ejbc - ClassNotFoundException

Executing the following
1. cd c:\weblogic
2. setenv
3. java weblogic.ejbc -classpath
C:\VisualCafeEE\Projects\Util\CLASSES;%classpath%;
C:\VisualCafeEE\Projects\JspBO\_JspBO.jar
C:\VisualCafeEE\Projects\JspBO\JspBO.jar
and getting ClassNotFoundException when trying to generate deployment JAR if
I put all classes from the C:\VisualCafeEE\Projects\Util\CLASSES in to the
_JspBO.jar then it works fine.
The stdErr is attached
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.

every possible combination of (ejb-ref) in the ejb-jar.xml and

Linked references fail and i get : **** not in archive $$$. It doesnt

however and the beans seem to deploy, but i really want to stabalize

Is there some way to force ONE classloader to deploy all the beans,

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).

WebLogic.ejbc vs weblogic.rmic

[att1.html]

Aseem Rastogi <[email protected]> writes:
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

Regarding Weblogic Portal certifications.

Hi,
I'm a beginner in Weblogic Portals.
Is there any certification with certification id "0B0-110" with respect to Weblogic Portals ? If yes, is there any prerequisites for that exam? We dont find any relevant information in this regard.
We also found other exam ids for Weblogic Portals which requires some prerequisites.
Please let me know if you have more details on Weblogic Portal certifications.
Thanks in advance,
Jeyageetha

Hello Jeyageetha,
This is the kind of information that can change at any time so check with Oracle University for the latest, but here is the story as of today:
The short answer is that the WebLogic Portal developer certification is now known as: "1Z0-110 Oracle WebLogic Portal 10g Developer" and that it does not have any required prerequisites but does have recommended prerequisites:
BEA WebLogic Portal 9/10: Develop Enterprise Portals: http://education.oracle.com/pls/web_prod-plq-dad/show_desc.redirect?dc=D70838GC10
OR
BEA WebLogic Portal 9/10: Develop Enterprise Portals – LWC: http://education.oracle.com/pls/web_prod-plq-dad/show_desc.redirect?dc=D54865GC10
OR
Oracle WebLogic Portal 10g R3: Develop Enterprise Portals: http://education.oracle.com/pls/web_prod-plq-dad/show_desc.redirect?dc=D56369GC10
If you look on the Oracle University website I think you'll find what you need:
OTN (Oracle Technology Network):
http://www.oracle.com/technology/index.html
"Certification" link goes to "Oracle University":
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=3
"Product Courses --> BEA" link:
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=84&group_id=1410
"BEA WebLogic Portal link:
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getlppage?page_id=212&path=WLPL
There is one learning path for administrators and one for developers. The dark gray shaded courses are marked as required.
To learn about the certification to which these courses apply, you can start at the "Certification" link at Oracle University:
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=39
If you look around there you will probably want to end up here:
"Oracle WebLogic Portal 10g Developer Certified Expert"
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=282
Also here:
"Important Changes to BEA Certifications"
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=285
I don't see a certification for administrators. You should probably ask Oracle University if that is what you want. You may want to ask them why they mark some courses as "required" in the course description but then only list "recommended" courses in the certification description. There are inconsistencies on the Oracle University website about what is a required prerequisite versus a recommended prerequisite and it is probably a mistake.

Regarding weblogic issue

Hi,
I have a problem with weblogic 8.1 server.
when i am trying to insert the fileds in a form and when i give the "clearing date" value as a blank it is displaying the value as '1/1/1900' in jsp.
whereas in Websphere it is not showing.
Ideally it should not show.
Please help me to resolve this issue if there are any settings to be made.

This is not enough information to help you. Do you have any code snippets and an explanation of what the inputs/outputs are?
