[EJB 3.0] - class cast exception
by razvanc
Hello,
I am using JBoss 4.0.4.GA and i have the following problem:
I have two ears,
- first contains the ejbs jar + the ejb interfaces jar. The ejb jar refers the ejb interfaces jar.
- the second ear contains a war archive that refers the ejb interfaces jar file. it also contains the ejb interfaces jar file in root.
I also changed the ear deployer.xml to have isolation and call by value set to true.
when I try to acquire a reference to a stateful session bean located in the first ear from the second ear, i get a class cast exception:
SEVERE: Error Rendering View[/view_server.xhtml]

at org.jboss.seam.interceptors.JavaBeanInterceptor$1.proceed(JavaBeanInterceptor.java:80)
basically after i've done some reading it seems it's a classloader problem.
however, i need to separate the two ear files as they will ultimately be deployed on separate machines.
Can you ples tell me how can i solve this?

I put thoes pojos into JBossCache-1.4.0.GA\tools\src and ran the ant all to generated the aopc classes(Persion.class,Persion$*.class,Address.class,Address$*.class,))
Then I tested POJOCache base on those class file, but hit error

[Tomcat, HTTPD, Servlets & JSP] - JBoss 4.0.2 and JDK 5.0
by sasi2103
Hi all,
I deployed an application on JBoss 4.0.2 with JDK 5.0
When I load one of my jsp page, that contains list with generics, (e.g. List), I get the following error:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 8 in the jsp file: /generics/upperboundwilcards.jsp
Generated servlet error:
Syntax error on token "<", invalid AssignmentOperator
An error occurred at line: 8 in the jsp file: /generics/upperboundwilcards.jsp
Generated servlet error:
Syntax error on token "=", != expected
An error occurred at line: 8 in the jsp file: /generics/upperboundwilcards.jsp
Generated servlet error:
Syntax error on token "<", ( expected
An error occurred at line: 8 in the jsp file: /generics/upperboundwilcards.jsp
Generated servlet error:
Syntax error on token "(", invalid Expression
My question: Is JBoss can't compile JSP's that compiled in JDK5.0?

[JBossWS] - Example for transmitting a pojo
by Juergen.Zimmermann
Is there a working example on how to transmit a pojo from the server to the client? Any hint is highly appreciated!
I'm using JBoss 4.0.4-Patch1 with EJB 3.0RC8_FD, JBossWS 1.0.2 and JSR-181 EJB endpoints with BASIC authentication.
I'm struggling with the transmission of pojos. I use wstools to generate jaxrpc-mapping.xml and the wsdl file. The jaxrpc-mapping.xml file is on the CLASSPATH. However, I always get exceptions like:
Call invocation failed: org.jboss.ws.binding.BindingException: org.jboss.ws.jaxb.UnmarshalException: Failed to parse source: Requested element {urn:mydomain}myproperty is not allowed in this position in the sequence. The next element should be myproperty; nested exception is: javax.xml.rpc.JAXRPCException: org.jboss.ws.binding.BindingException: org.jboss.ws.jaxb.UnmarshalException: Failed to parse source: Requested element {urn:mydomain}myproperty is not allowed in this position in the sequence. The next element should be myproperty
BTW, I tried GLASSFISH to implement my client and had only a few problems. Is there no chance to use JBossWS for pojos? Actually I don't want to use two products...
