Anyone successfully deployed a Creator app to Tomcat ...?

Question

Without running into connection pool problems?
If so, could you share some insights?

Answer 1

There are two good tutorials on this
http://developers.sun.com/prodtech/javatools/jscreator/reference/tips/deploy_to_tomcat.html
and at
http://wiki.java.net/bin/view/People/DeployingCreatorApps
However I thought I would add something new here which how to modify the generated build-impl.xml run from inside of creator (EA2) to deploy to tomcat when hitting the green arrow button and run inside of tomcat instead of deploying to SunAppServer8. There are several nice things about this. Im developing on windows machine and deploying to tomcat 5.5.9 on linux which I have mounted via samba drive , however you could also have tomcat running locally as well.
Follow the isntructions above in the tutorials ... namely
You need to make sure the the Jdbc driver of your choice is in
$CATALINA_HOME/common/lib
And need
To put
jstl.jar standard.jar
into
$CATALINA_HOME/shared/lib
Configure the dbcp connection pool in server.xml for your application. Alternatively you can place this in the context.xml file.
Here is an example
<Context path="/yourapp" docBase="yourapp"
debug="5" reloadable="true" crossContext="true">
<Resource name="jdbc/schemauser" auth="Container" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="user" password="pass" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/schemauser?zeroDateTimeBehavior=round"/>
</Context>
And configure a datasource in your app with the same name as what you put in your server.xml file (in the above example this would be schemauser.
You will next need to modify the generated build-impl.xml to export war, copy file to $CATALINA_HOME, stop , start the web application and display browser.
In order to reload the app we need the version of Catalina ant jars in the asant classpath
Copy
catalina-ant.jar
catalina-deployer.jar
from
$CATALINA_HOME/server/lib
to
C:\Program Files\Sun\Creator2ea2\SunAppServer8\lib\ant\lib
and
C:\Program Files\Sun\Creator2ea2\ide5\ant\lib
Then restart the IDE, must restart after jars are copied.
Then copy the build-impl.xml from inside of My Documents/creator/src/nbproject to build-impl-original.xml ( to make a back up).
Next modify the build-impl.xml to add the Catalina Ant tasks
Here is the modified section
Place this in between the export.war and the run target and comment out the original run target
<!--- ORIGINAL export -->
<target name="export.war" depends="dist">
<copy file="${dist.war}" tofile="${jscreator.dest.war}"/>
</target>
<property environment="env" />
<property name="catalina.home" value="${env.CATALINA_HOME}" />
<property name="manager.url" value="http://yourserver:8080/manager" />
<property name="manager.username" value="user"/>
<property name="manager.password" value="pass"/>
<property name="app.name" value="subscriber"/>
<property name="app.path" value="/${app.name}"/>
<target name="export.war.tomcat" depends="dist">
<copy file="${dist.war}" tofile="${catalina.home}/webapps/${app.name}.war"/>
          <unwar src="${catalina.home}/webapps/${app.name}.war" dest="${catalina.home}/webapps/${app.name}"/>

<!-- HERE IS THE MAIN TASK THAT GETS RUN WHEN YOU HIT THE RUN BUTTON-->
<!--
Original Run target COMMENT THIS OUT

Then test by hitting the run button on your project and see what happens.
Let me tell you if your editing from a windows box and you dont have 2gb of memory its pretty nice to not have to run the app server!
