Java XML Tutorial and How to read UTF-8 XML file in Java – (SAX Parser)

First Step:
Convert the cert into a Java Keystore:
openssl pkcs12 -export -name mycert.local -in /etc/ssl/certs/mycert.local.cert -inkey /etc/ssl/private/mycert.local.key -out mycert.local.keystore.p12

Second Step:
Import the new keystore (Using the primary java keystore of an Oracle Java install on Linux here:
keytool -importkeystore -srckeystore mycert.local.keystore.p12 -destkeystore /usr/lib/jvm/default-java/jre/lib/security/cacerts -srcstoretype pkcs12

Debugging with eclipse tips from codecentric.de

Particularly useful to me were the sections:
Navigation: Drop to Frame, Variables View: Show Logical Structure

The stuff on Detail Formatters was useful as well.

Note that Eclipse will truncate long strings in the detail view, but you can increase this limit. However, with very large values, you'll find it much easier to change the underlying code adding a log statement due to the detail view being really slow to render.

In your ~/.grails/settings.groovy

String archivaUsername = "daniel"
String archivaPass = ""
String archivaHost = "myArchivaHost.bowerstudios.com"
grails.project.ivy.authentication = {
credentials {
realm = "Repository Archiva Managed releases Repository"
host = archivaHost
username = archivaUsername
password = archivaPass
}
}
grails.project.repos.bowerStudiosArchiva.url = "http://${archivaHost}/archiva/repository/releases"
grails.project.repos.bowerStudiosArchiva.username = archivaUsername
grails.project.repos.bowerStudiosArchiva.password = archivaPass
grails.project.repos.default = "bowerStudiosArchiva"

Then, as long as you have the release plugin installed:
To install to your local maven cache:
grails maven-install
To install to Archiva:
grails maven-deploy

Created a private key and cert request using openssl. Sent it off to get a Rapid ssl cert, and had to do the following:

Concatenate the primary and secondary ca certs with the cert issued by rapid ssl:
cat primary_inter.cer secondary_inter.cer host.bowerstudios.com.cert > certs.cert

Next, I used openssl to create a "combined store"
openssl pkcs12 -export -in certs.cert -inkey host.bowerstudios.com.key -certfile certs.cert -name host.bowerstudios.com -out host.bowerstudios.com.p12

Now, import the keystore into a java keystore
keytool -importkeystore -srckeystore host.bowerstudios.com.p12 -srcstoretype pkcs12 -destkeystore tomcat.keystore -deststoretype JKS

In the DataSources Config:
// datasource via jndi
dataSource {
pooled = false
jndiName = "java:comp/env/jdbc/myAppDatasource"
}

In Tomcat's lib directory, you'll need your database driver, tomcat-dbcp.jar and tomcat-jdbc.jar

In Tomcat, in the server context.xml, in the Context element:
<ResourceLink type="javax.sql.DataSource" name="jdbc/myAppDatasource" global="jdbc/myAppDatasource" />

In Tomcat in the server's server.xml, in the GlobalNamingResources element:
<Resource name="jdbc/myAppDatasource"
auth="Container"
type="javax.sql.DataSource"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
testWhileIdle="true"
testOnBorrow="true"
testOnReturn="false"
validationQuery="SELECT 1"
validationInterval="30000"
timeBetweenEvictionRunsMillis="30000"
maxActive="10"
minIdle="5"
maxWait="10000"
initialSize="10"
removeAbandonedTimeout="60"
removeAbandoned="true"
logAbandoned="true"
minEvictableIdleTimeMillis="30000"
jmxEnabled="true"
jdbcInterceptors="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState"
username="root"
password="password"
driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://127.0.0.1:5432/my_db"/>

If you're sharing it with a spring app, you can use the jee namespace in your spring app:
xmlns:jee="http://www.springframework.org/schema/jee"
and then:
<jee:jndi-lookup id="dataSource" jndi-name="jdbc/myAppDatasource">

You can try on the command line:

java -d64 -version

If it's not a 64-bit version, you'll get a message that looks like:

This Java instance does not support a 64-bit JVM. Please install the desired version.
