Yes, you will not get it to work because of the different JBoss versions. If the book uses JBoss AS 3, then in order to get their sample to work you need JBoss AS 3. In JBoss AS 4 files like

%JBOSS_DIST%\client\jcert.jar; %JBOSS_DIST%\client\jmx-connector-client-factory.jar; %JBOSS_DIST%\client\jmx-ejb-connector-client.jar;

Are not in the client directory. Those jars do not exist in JBoss 4.0.

So you can either use the EJB tutuorials from JBoss that work with JBoss 4.0, or look at your bat file and remove all the jars that are no longer in the client directory of JBoss.

Thanks a lot for the explanation Mark. Really appreciate.

I'll try to change the content of the bat file and see if it works.

Thanks again.

Hello Sheethal,

Well, according to this book J2EE RI is a server, although a simple one. But I might have misread it or misinterpreted it so please advise me.

Thanks

Thanks for the reply Vyas. I'll try to use NetBeans.

Hello,

I am using Sun Application Server 9 on my machine. I also have JaveEE and I was trying to deploy one of the sample ejb examples as described in the JavaEE Tutorial. In the tutorial, ant is used to build and deploy the project. When I typed ant it built and gave me all the necessary files but when I tried to deploy it using ant deploy, it gave me this error:

C:\Documents and Settings\HP_Administrator\Desktop\javaeetutorial5\examples\ejb\
converter>ant deploy
Buildfile: build.xml

check:

BUILD FAILED

roject\app-server-ant.xml:417: Property javaee.server.passwordfile not specified.
Please specify the javaee.server.passwordfile property in 'bp-project/build.properties'.
You will also need to ensure that the passwordfile is present and contains AS_ADMIN_PASSWORD.

I don't really understand what this error means. Can someone please help me with this.

Hello,

I am trying to set up J2EE 1.3 RI on one of my machines for running sample applications from the book Head First EJB.

But when I try to run this server I get the following error:

C:\Documents and Settings\Administrator\Desktop\HFEcode\HFEJBCODE\advice>j2ee -v
erbose
ERROR: Set J2EE_HOME to the path of a valid j2sdkee.

I have already set the path of J2EE_HOME to C:\j2sdkee1.3.1

I do not understand why it isn't working and would be really thankful if somebody could help me with this.

Thanks

Hello,

I am new to EJB and am trying EJB for dummies. I tried to deploy a sample application that can be downloaded from the book website - HelloWorld.

I followed the instructions and everything went well till I reached the section where I have to run this bat file. I get errors when I run it.

By the way, Dummies uses JBoss 3.0.0 while I am using JBoss-4.2.0.GA so I believe there is a problem with the path. Two things I noticed. Firstly, in the bat file the author has used %JBOSS% - Should I change it to something else. Secondly, I notice the files listed in the bat file are different from the ones I have in the client directory of my JBoss installation. So do they all need to be listed or changed.

I have pasted both the bat file and the error I get below. Would be really thankful if someone kindly guides me how I can solve this isssue.

Thanks in advance.

I'd suggest you not compile classes into the same directory as the source, but specify a different destination directory. Either way, you must include the destination directory in your classpath. example:
javac -c ../../../WEB-INF/classes;%classpath% -d ../../../WEB-INF/classes LoginBean.java

Hello Merrill,

Thanks for the reply and advice. I tried what you suggested but I got a lot of errors. The whole of the errors are pasted below. I think I might have to add something to the classpath. Can you please advise what I can do?

Thanks in advance.

Hello,

I am writing a simple JSP page in which the user enters the color that she wants for background and on submission the color is displayed in the background. I want to modify the code so that if the user hits submit without entering anything, then the color should be blue.

My attempt is below. Can somebody please advise where I am wrong as at the moment if I leave the field blank then it displays white background.

Thanks
Ricky

Hi,
You may try to get the background parameter from the request and, if not null, set it into the application scope.Instead, if it's null, you read it from the application scope.

Hello Mirko,

Thanks for the tip. I'll try that.

Cheers

Hello,

I am working on this exercise (pasted below) from the book More Servlets and JSPs by Marty Hall. Would be really thankful if somebody could advise how I should approach this exercise.


"Make a JSP page that lets the user supply a request parameter indicating the background color. If no parameter is supplied, the most recently used background color (from a previous request by ANY user) should be used."

I have attempted this exercise but don't really know how to approach the second part.

Thanks in advance.

Refactor your code to return a value at the end of the method. So in your if blocks you set the string you want to return to some variable.

if(..) { value = "This is want I want to return"; } ... return value;

Thanks a lot Kel.

That resolved the issue.

Really appreciated.

Hi,

I have written a simple method that returns the name passed and an int variable that counts the no. of visits.

When I try to compile this it give me an error saying that a "return statement is required".

Would be thankful if somebody advised me how I may resolve this issue.

public String say(String name) { this.name = name; visitCounter ++; if (visitCounter == 1){ return "Hello " + name; } else if (visitCounter == 2){ return "Welcome back, " + name; } else if (visitCounter >= 3){ return "You are very welcome, " + name; } }

Thanks
Ricky
