Building the correct WARs for Tomcat

[tim_perrett]

Hey all

I have constucted an Ant script that *looks* to build the correct type of WAR file for deployment in tomcat. However, and im not sure if i think this is a tomcat issue or one related to seam but it doesnt actually deploy in tomcat. I have set it up so that it includes the correct JARs... here is my ant script (below)

Im using tomcat 6, and i recive the following error:

SEVERE: Error listenerStart
Apr 21, 2007 12:43:19 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/seam-hello] startup failed due to previous errors

The seam app i am trying to deploy only has one class, that is a simple hello world example!! lol I dont belive it cant be this difficult to deploy surly?

Any help would be appreciated guys

All the best

Tim

Not that I know anything about tomcat, but what is the previous error?

[tim_perrett]

From what i can find out it seams to be a generic error that tomcat produces when it cant do somthing. Which is, well, not very helpfull to be honest!

There looks to be an active seam comunity but i guess your all using JBoss AS? I am running OSX and linux, so perhaps I might change development platform perhaps... what do people suggest, as i am wholy flexible at this point in time.

I am only trying to do a simple hello world app at the moment yet there do not seem to be any basic basic tutorials on first getting running, especially when using tomcat! lol

All the best

Platform wise theres a complete mix, but I think most of us use JBoss AS on a day-to-day basis. Thats not to say it doesn't work on Tomcat (I just never use Tomcat). Chapters 1 and 2 of the reference manual should give you a good intro to Seam and to starting a project (Seam-gen really is the way to go)

It may be the case you need Tomcat 5.5...

[tim_perrett]

For sure, i have the examples working on tomcat no problem at all. Thats the ironic thing.... The examples worked out of the box, it just did what it said on the tin! lol

I have been using seam-gen to build my projects so far with no problems. I just thought that i would keep it 100% simple, with a good old hello world example!

I get errors when i try to deploy the examples into my JBoss install however. Is there any additional config i would need to do from an out of the box install of JBoss on OSX?

Cheers

I get the following error when deploying to Jboss

org.jboss.deployment.DeploymentInfo@37464ce7 { url=file:/Applications/jboss-4.0.5.GA/server/default/deploy/jboss-seam-contactlist.ear }

Please if anyone has any ideas that would be splendid!

Install the AS using the JEMS installer, make sure to choose EJB3, as described in the getting started guide.

[tim_perrett]

lol excellent - its working, the examples anyway!

JBoss gives me better errors than tomcat and seems to work just as well so all good. Just a quick one about seam...

After creating a new project using seam gen, would you expect that to just work or does it *always* require extra config to start off with?

Cheers

Tim

[pmuir]

Well, if you generated an empty project then it should work ootb. If it's got some reverse engineering in it from an existing database schema it may need some tweaking.

[tim_perrett]

oh ok cool.

The thing is it keep generating Authenticator.java..... which looks to be a method for loggin in, wont this cause errors ootb?

I have the examples all working both tomcat and JBoss AS now, but i'll be dammed if i can make an seam-gen one work correctly lol

Even with a basic helloworld class it complains there is no table called "Greeter" - why would it need a table to say helloworld? is this some kind of built in default?

package com.timperrett.seam.helloworld;

import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import org.jboss.seam.annotations.Name;

@Entity
@Name("greeter")
public class Greeter implements Serializable {

 private static final long serialVersionUID = 1L;

 Long id;

 String message = "Hello world!";

 @Id @GeneratedValue
 public Long getId() {
 return id;
 }

 public void setId(Long id) {
 this.id = id;
 }


 public String getMessage() {
 return message;
 }

 public void setMessage(String message) {
 this.message = message;
 }
}

Cheers, appologies for these dumb questions, im very new to seam!

The authenticator is indeed for security, but the authenticate method just returns true (i.e. you have passed authentication) by default.

You've made your class below an @Entity - so it's backed by the database. Set hibernate.hbm2ddl.auto to true in persistence.xml for Hibernate to autonmatically create the schema. Also, to start, its best to use the HSQL defaults suggested by seam-gen as then you don't have to worry about problems connecting to the database.
