Running Seam examples with Apache Tomcat

Using seam 2.0.1 with tomcat 6.0.16, I had to add asm.jar to the deployed war's WEB-INF/lib/ directory.

which asm.jar have you used, with asm-3.1.jar I receive: java.lang.NoSuchMethodError

I simply copied the jar file bundled in the seam 2.0.1-GA download, which is located at jboss-seam-2.0.1.GA/lib/asm.jar.

thanks,with that jar is working

First. there isn't lib//hsqldb.jar file in jboss-seam//examples//jpa directory. I found it on seam-gen//lib directory.

Second. I have following in tomcat log:

SEVERE: Error listenerStart 13.03.2008 15:13:48 org.apache.catalina.core.StandardContext start SEVERE: Context jboss-seam-jpa startup failed due to previous errors Example app not working for me. Tomcat6, Seam2, Java6

I am having issues deploying on Tomcat 6 as well. You should check your logs ... you will probably find NoClassDefFoundError. I've had to copy several of the war's jars into Tomcat/lib. So far, I've had to copy all of the jsf libs and commons-logging.jar. Particularly irking is the fact that the commons-collections.jar in the war has the wrong version ... the example apparently needs the collection that contains AbstractHashMap, so I had to find the jar containing AbstractHashMap.

My latest issue is an ajax4jsf class not found... i can't find any ajax4jsf jars anywhere in the war. I must be doing something wrong: this is way harder than it should be.

I replaced the commons-collections.jar in the generated war with commons-collections-3.2.jar and added the asm.jar as well, and it works now! Link to download : commons-collections-3.2.jar

I am also trying to make seam simply work on tomcat with facelets, jsf and richfaces but with no luck. The webapplication seems to be working, but with weird unresolved issues: 1) I get this exception: java.lang.RuntimeException: error while reading /WEB-INF/components.xml at org.jboss.seam.init.Initialization.initComponentsFromXmlDocument(Initialization.java:154) at org.jboss.seam.init.Initialization.create(Initialization.java:104) at org.jboss.seam.servlet.SeamListener.contextInitialized(SeamListener.java:34) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3843) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4350) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:791) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:771) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:525) at org.apache.catalina.startup.HostConfig.deployDescriptor(HostConfig.java:626) at org.apache.catalina.startup.HostConfig.deployDescriptors(HostConfig.java:553) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:488) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:1147) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:311) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:117) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1053) at org.apache.catalina.core.StandardHost.start(StandardHost.java:719) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:443) at org.apache.catalina.core.StandardService.start(StandardService.java:516) at org.apache.catalina.core.StandardServer.start(StandardServer.java:710) at org.apache.catalina.startup.Catalina.start(Catalina.java:578) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:288) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413) Caused by: java.lang.IllegalStateException: Two components with the same name and precedence - component name: org.jboss.seam.transaction.transaction, component classes: org.jboss.seam.transaction.EntityTransaction, org.jboss.seam.transaction.HibernateTransaction at org.jboss.seam.init.Initialization.addComponentDescriptor(Initialization.java:489) at org.jboss.seam.init.Initialization.installComponentFromXmlElement(Initialization.java:389) at org.jboss.seam.init.Initialization.installComponentsFromXmlElements(Initialization.java:280) at org.jboss.seam.init.Initialization.initComponentsFromXmlDocument(Initialization.java:150) ... 26 more

2) I get this warning in the log file: The listener org.jboss.seam.servlet.SeamListener is already configured for this context. The duplicate definition has been ignored

3) This is the most annoying issue (since from the rest I could have ignored at this point in development): In a simple login example I am doing it seems like the action method is called twice in the server. I have a feeling this will happen in any other action and not just in this login example... Mybe it is related to the message I am getting at 2)...

Did you ever get this working.??

I am starting to add Seam to my JSF/RichFaces Project in Tomcat 6

Phil

i could run without any problem. i've just followed the instruction except ant tomcat55 instead of ant tomcat6 and that it, its working now.

Ant? We are need for IDE c support Seam. And problems are present!

But...

See my forum, questions and answers, for this problem.

|Command line deployment worked fine for me with:

Tomcat 6.0.16
Seam 2.0.3.CR1

I copied Seam's hsqldb.jar to Tomcat's lib/, then
ant tomcat6
then copied jboss-seam-jpa.war to tomcat's webapps/ 

I had no issue in running seam jpa example with tomcat 6(using ant tomcat6).

I would suggest that most people should stick with JPA (instead of embedded ejb)- as JPA is just a simple wrapper over hibernate methods.

You could seem my blog at : http://www.jroller.com/seam on how to setup seam-gen with tomcat 6.(which is ultimately what most people would need -after they tried running the examples)

In second step (Go into the boss-seam/examples/jpa directory) did i want to build or just copy this to tomcat what i need to do???? Where i can download this war file... dist-tomcat6/jboss-seam-jpa.war

please wats wrong with my project..... FAIL - Application at context path /jboss-seam-jpa could not be started

Download and install Tomcat 6.x
-------------------------------
(http://tomcat.apache.org/download-60.cgi)
.
.
.
mkdir /Library/Tomcat
gunzip apache-tomcat-6.0.20.tar.gz

tar -xvf apache-tomcat-6.0.20.tar /Library/Tomcat

the above line is wrong, replace with:

cd /Library/Tomcat
tar -xvf path-to-downloaded-file/apache-tomcat-6.0.20.tar

.
.
.

The rest of it remains the same. Sorry about that. path-to-downloaded-file should be replaced with the actual path to where you downloaded the file.

org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart Dec 20, 2009 12:24:56 PM org.apache.catalina.core.StandardContext start

Everything i deployed in tomcat server while run this http://localhost:8080/jboss-seam-registration/ showing the above error.. Please reply..

I had to add the following libs in apache-tomcat-6.0.20/lib

jsf-api.jar
dom4j.jar
log4j-boot.jar

tem certeza que esse negócio roda mesmo no tomcat? Eu não consigo rodar de jeito nenhum! Será que não é melhor dizer logo que não roda?

Frankly speaking, it is not easy to deploy a seam application in Tomcat. In the websites of seam, they always talk big, they advertise in such a way that it seems like a plug-n-play type deployment; but real story is different.

Yes it is possible to deploy in Tomcat but it comes with a price of painful tasks. First of all, you will get some ClassNotFoundException, you resolve those one by one; then you will get a conflict class file versions; you resolve those and then you will get project facets issue.. and this goes on ... simply put, it is not a easily deployable in Tomcat. So is true for Weblogic and WebSphere. The only painless deployment that is possible is with JBoss AS.
