hi,

i have an EJB 3.0 application which extract text-data from MySQL Database. Only the EJB application works fine.

Now, i want get the data in compressed form by using CompressedSocket. Therefore, i've create the CompressionSocket classes from the "org.jboss.test.jrmp.ejb" package. In additional, i wrote the following jboss.xml deployment descriptor:

<?xml version="1.0"?>
<jboss>

 <container-configurations>
 <container-configuration>
 <container-name>Standard Stateless SessionBean</container-name>
 <invoker-proxy-binding-name>stateless-compression-invoker</invoker-proxy-binding-name>
 <container-invoker-conf>
 <Optimized>true</Optimized>
 <RMIObjectPort>0</RMIObjectPort>
 <RMIClientSocketFactory>de.einsundeins.socket.CompressionClientSocketFactory</RMIClientSocketFactory>
 <RMIServerSocketFactory>de.einsundeins.socket.CompressionServerSocketFactory</RMIServerSocketFactory>
 </container-invoker-conf>
 </container-configuration>
 </container-configurations>

 <enterprise-beans>
 <session>
 <ejb-name>TextBean</ejb-name>
 <configuration-name>Standard Stateless SessionBean</configuration-name>
 <invoker-bindings>
 <invoker>
 <invoker-proxy-binding-name>
 stateless-compression-invoker
 </invoker-proxy-binding-name>
 <jndi-name>CompressedApp/TextBean/remote</jndi-name>
 </invoker>
 </invoker-bindings>
 </session>
 </enterprise-beans>

 <invoker-proxy-bindings>
 <invoker-proxy-binding>
 <name>stateless-compression-invoker</name>
 <invoker-mbean>jboss:service=invoker,type=jrmp, socketType=CompressionSocketFactory</invoker-mbean>
 <proxy-factory>org.jboss.proxy.ejb.ProxyFactory</proxy-factory>
 <proxy-factory-config>
 <client-interceptors>
 <home>
 <interceptor>org.jboss.proxy.ejb.HomeInterceptor</interceptor>
 <interceptor>org.jboss.proxy.SecurityInterceptor</interceptor>
 <interceptor>org.jboss.proxy.TransactionInterceptor</interceptor>
 <interceptor>org.jboss.invocation.InvokerInterceptor</interceptor>
 </home>
 <bean>
 <interceptor>org.jboss.proxy.ejb.StatelessSessionInterceptor</interceptor>
 <interceptor>org.jboss.proxy.SecurityInterceptor</interceptor>
 <interceptor>org.jboss.proxy.TransactionInterceptor</interceptor>
 <interceptor>org.jboss.invocation.InvokerInterceptor</interceptor>
 </bean>
 </client-interceptors>
 </proxy-factory-config>
 </invoker-proxy-binding>
 </invoker-proxy-bindings>

</jboss>

Now, i get the same result when i deploy and start the application as previous. I don't get an error message if i rename the clientSocketFactory or serverSocketFactory class. First, i think that the jboss.xml file is never read but the application doesn't run when i modify the Enterprise-bean settings in this file.

The code of the TextBean.class:

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import org.jboss.annotation.ejb.RemoteBinding;
import de.einsundeins.ccsys.util.DBConnection;
import de.einsundeins.ccsys.interfaces.*;


@Stateless
@Remote(TextRemote.class)
//@RemoteBinding (jndiBinding="CompressedApp/TextBean/remote")
public class TextBean implements TextHome, TextRemote {

 private static final String QRY_TEXT_SEL = "select text.data from textandbinary.text LIMIT 100";


 public String getText() {


 try {
 Connection ConMySQL = DBConnection.dbMysql(DBConnection.MySQLURL);
 PreparedStatement prepStmt = ConMySQL.prepareStatement(QRY_TEXT_SEL);
 ResultSet rs = prepStmt.executeQuery();
 String text = "";

 while(rs.next()){
 text = text + rs.getString("data");
 }
 return text;
 }
 catch(ClassNotFoundException ex){
 ex.printStackTrace();
 }catch (SQLException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 }

 return null;
 }
}

TextRemote.class Interface:

public interface TextRemote{

 public String getText();

}

CompressedClient.class

import de.einsundeins.ccsys.interfaces.*;
import javax.naming.InitialContext;



public class CompressedClient {

 public static void main(String args[]){

 try{
 InitialContext ctx = new InitialContext();

 TextRemote remote = (TextRemote)ctx.lookup("CompressedApp/TextBean/remote");
 System.out.println(remote.getText());
 }
 catch(Exception e){
 e.printStackTrace();
 }
 }
}

I deploy the application as an EAR-file with following structure:

CompressedApp.ear
- application.xml --> META-INF
- ejb-app.jar
- TextBean.class
- TextRemote.class
- CompressionClientSocketFactory.class
- CompressionServerSocketFactory.class
- CompressionServerSocket.class
- CompressionSocket.class
- CompressionInputStream.class
- CompressionOutputStream.class
- CompressionConstants.class
- jboss.xml --> META-INF

Is it possible that i have make for error in the jboss.xml file or i have forget about something?

I don't know it.

I would be grateful for every help.

Best regards
Markus
