create new app as follows
cd ~/projects-try

sencha -sdk $EXTJS_SDK generate app CCAProject ~/projects-try/ccaApp

== to build app first cd to it and then build
cd ~/projects-try/ccaApp

Make sure you set the arraysize of SQL*PLUS (or whatever) small enough, otherwise you will get a bunch of results at once, not when they occure.

set arraysize 1

select * from table(dummy());

gives

COLUMN_VALUE

git and eclipse

Git ref 
to import a project into git from say CVS

cd ~/projects/camscapa-project/
mkdir CAMS2
cp -R ../cams2-project/CAMS2/* CAMS2
cd CAMS2

mvn clean

for d in `find -type d -name 'CVS'`; do rm -rf $d; done
for d in `find -type d -name '.settings'`; do rm -rf $d; done
for d in `find -type f -name '.project'`; do rm -rf $d; done

git init
git add .
git commit -a -m 'all commit first time'
cd ..
git clone --bare ./CAMS2 ~/z-git-repos/CAMS2.git
mv CAMS2 CAMS2_after_init
git clone git://rpradeshik/CAMS2.git
cd CAMS2
pwd

# add gitigone with target classes etc.,

git add .
git commit -m 'ingone file' .
git push

To import in eclipse

1. Open "Git Perspective", do "Add existing local repo"  and choose "~/projects/camscapa-project/CAMS2" 
2. RClick on CAMS2 node and select "Import Projects"
3. in 3 radio options choose "Import as general Project", then "CAMS2", finish
4. This should bring CAMS2 as project into workspace, goto java perspective
5. to import single modules inside CAMS2 say "cams-dri" RClick and do maven import
6. Make sure maven 304 is in eclipse installation

To update version of maven for portal project
Manually update express/portal/pom.xml

mvn versions:update-child-modules -DgenerateBackupPoms=false
OR
mvn versions:set -DnewVersion=1.3-SNAPSHOT
mvn versions:commit

JBoss 7 re-deployment

The reason using these manual steps is war:inplace makes a mess if there are war overlays
In Jboss standalone.xml make sure you disable scanning for exploded deploys
<subsystem xmlns="urn:jboss:domain:deployment-scanner:1.1"> <deployment -scanner="-scanner" auto-deploy-exploded="false" auto-deploy-zipped="true" path="deployments" relative-to="jboss.server.base.dir" scan-interval="5000"> </deployment></subsystem>
Make sure you install inotify-tools (in ubuntu) test for exec as inotifywait
in war maven pom.xml have for exploded as <build> <plugins> <plugin> <groupid>org.apache.maven.plugins</groupId> <artifactid>maven-war-plugin</artifactId> <configuration> <webappdirectory>${env.JBOSS_HOME}/standalone/deployments/test-ui.war</webappDirectory> </configuration> </plugin> </plugins> </build> </project>
To deploy un-zipped run command as "mvn war:exploded"
To force reload of app in jboss make a touch as "touch $JBOSS_HOME/standalone/deployments/test-ui.war.dodeploy"
To Make a inotify cron rsync do as follows, have a shell script as #!/bin/bash SRC_DIR=src/main/webapp/jsp EXCLUDES="CVS" DESTN_DIR=$JBOSS_HOME/standalone/deployments/test-ui.war while inotifywait -r --exclude $EXCLUDES -e modify -e create -e delete $SRC_DIR ; do rsync -azrv --exclude "$EXCLUDES" $SRC_DIR $DESTN_DIR done

to install conscript do this
>>curl https://raw.github.com/n8han/conscript/master/setup.sh
it pus cs in ~/bin

some help:

scala example https://github.com/padcom/spring-example

append with EMPTY new line another sbt plugin common for user machine as
~/.sbt/plugins/plugins.sbt
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.1.0-RC1")


run as follows to create a sample project
g8 chrislewis/basic-project
(say you create testApp)

to create eclipse files

cd testApp

sbt eclipse (this create eclipse files, use Indigo to open project) !
