how can i add parameter annotations to the parameters of a method?
*Assume the scenario*
public class A(){
public int sum(int a,int b){
return a+b;
}
public int totalsum(int a,int b,int c){
return a+b+c;
}
}
now the name of this class is passed to the method which will dynamically generate a new well annotated class, say dynamic(String className). The new class should appear as:
@Start
public class newA(){
@MethodStart
public int sum(
@Param1(value="1st Parameter")
int a,
@Param2(value="2nd Parameter")
int b
){
return a+b;
}
public int totalsum(
@Param1(value="1st Parameter")
int a,
@Param2(value="2nd Parameter")
int b,
@Param3(value="3rd Parameter")
int c
){
return a+b+c;
}
adding annotation to the start of the methods and class is simple but the trickiest part is adding parameter annotations to the variable no of parameters. i found few users on net discussing a solution to this problem but it didn't seems to be working.

[Javassist Development] - invoking a method with the help of object instance from a dynamically generated method using javassist

"invoking a method with the help of object instance from a dynamically generated method using javassist"

--------------------------------------------------------------
i want to invoke a method with the help of object instance of the same class from within a method which i m generating dynamically with the help of javassist, i m finding it difficult to implement. A similar method is present with javassist called http://www.csg.ci.i.u-tokyo.ac.jp/~chiba/javassist/html/javassist/CtNewMe... delegator
for reference : with the help of delegator we can call the same method with super
int f(int p, int q) {
return super.f(p, q);
}
i wish to generate the method f dynamically and call the base class method f with the help of the object instance of base class which is injected to the dynamically generated class.
int f(int p, int q) {
return objectInstance.f(p, q);
}
i m getting this objectInstance before generating this class and use it to set the field which is also being added dynamically to this class.
*assume the scenario below for better understanding:*
public class A(){
public A(Object B,Object C){//A's constructor}
public int f(int p, int q){
return p+q;
}
}
main(){
C c=new C();
B b=new B();
A a=new A(b,c);
dynamic(a);
}
i want to code dynamic(Object objectInstance) i a way such that the dynamically added class looks like...
public class newA(){
private Object objectInstance;
public void setter(Object obj){
this.objectInstance=obj;
}
public Object getter(){
return this.objectInstance;
}
public int f(int p, int q) {
return objectInstance.f(p, q);
}
}

[EJB3 Development] - JBoss 7.1.1 MDB with IBM MQ - MessageDriven Annotation not configurable
by Bharadwaja Dasari

"JBoss 7.1.1 MDB with IBM MQ - MessageDriven Annotation not configurable"
To view the discussion, visit: https://community.jboss.org/message/821608#821608
--------------------------------------------------------------
I have implemented MDB with Jboss 7.1.1 using IBM MQ Listener. My Listener Code is below
@MessageDriven(
activationConfig = {
@ActivationConfigProperty(propertyName = "hostName", propertyValue = "111.11.11.11"),
@ActivationConfigProperty(propertyName = "port", propertyValue = "1420"),
@ActivationConfigProperty(propertyName = "channel", propertyValue = "Channel Name"),
@ActivationConfigProperty(propertyName = "useJNDI", propertyValue = "false"),
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
@ActivationConfigProperty(propertyName = "destination", propertyValue = "Name of Destination Queue"),
@ActivationConfigProperty(propertyName = "queueManager", propertyValue = "Queue Manager Name"),
@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"),
@ActivationConfigProperty(propertyName = "maxSession", propertyValue = "50")
})
@ResourceAdapter(value="wmq.jmsra.rar")
All this works perfectly(only change here is I have masked the actuals and replaced it with dummies in property values) but the problem is this is all hardcoded. I want it to be configurable, like say if I am in one environment, I want to pick it from properties files for that particular environment
OR if I use the command to start ./standalone -c standalone-full-xyz.xml, and this standalone-full-xyz.xml should have all the config properties for that environment, so atleast that will help make it configurable
How can I acheive this? Any help.

Actually we are migrating from Jboss-4.2.2GA to Jboss As7 it is good to work
with Jboss As7 but the problem is that in Jboss-4.2.2GA the SSL is enabled
and working fine for HTTPS with port 8443 for given following configuration (1)
in Server.xml.
1. SSL Configuration for Https Secure port in *Jboss-4.2.2 GA*
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="250" scheme="https" secure="true"

sslProtocol="TLS"
SSLHonorCipherOrder="On"
ciphers="SSL_RSA_WITH_RC4_128_MD5,SSL_RSA_WITH_RC4_128_SHA"

Where as in *Jboss AS7* with given following configuration (2) in Standalone.xml when
start up jboss it throws the following error observed in server.log
2. SSL Configuration for Https Secure port in Jboss As7

Following is KeyStore information
====================================
> keytool -v -list -storetype PKCS12 -keystore server.keystore
Enter keystore password:
Keystore type: PKCS12
Keystore provider: SunJSSE
Your keystore contains 1 entry
Alias name: 1
Creation date: Jun 5, 2013
Entry type: PrivateKeyEntry
Certificate chain length: 1
Certificate[1]:
Do i need any changes in configuration of Jboss AS7 to Successfully enable SSL in as compared to Jboss 4.2.2GA ?
what "keystoreFile" element in Jboss 4.2.2GA configuration represents and
what "certificate-key-file" element in Jboss AS7 configuration represents
These two represents same (i.e keystore) or different ?
Please suggest me for the above so that can move further.
Thank you in advance

Hi,
i'm trying to migrate an application from jboss 5 to version 7.1.
In my application there is a 2.1 version BMP entity...
i've searched throught the documentation but i cannot find how to migrate this portion of configuration...
in my jboss.xml (jboss 5) i have :
...
...
<container-configurations>
<container-configuration extends="Standard BMP EntityBean">
<container-name>Clustered Legacy Locked BMP EntityBean</container-name>
<instance-cache>org.jboss.ejb.plugins.PerTxEntityInstanceCache</instance-cache>
<locking-policy>org.jboss.ejb.plugins.lock.NoLock</locking-policy>
<commit-option>B</commit-option>
</container-configuration>
</container-configurations>
...
...
Any suggestions? how could i configure jboss7.1 so that it behaves as in JBoss 5.
Thanks,
Ale
p.s.: sorry for my english...
