Ant Script To Sign A JAR File

To sign a JAR file you need a ‘keystore” first. You can create a sample keystore using the following simple command.

keytool -genkey -keystore <filename.store> -alias <aliasname>

After creating the keystore, you can add the following Ant tag to sign the JAR file using it.

<signjar jar="<JAR file to be signed>" alias="<Keystore Alias Name>" 
                keystore="<Keystorefile.store>" storepass="<Keystore password>"/>

Attributes used are

jar – The JAR file path which needs to be signed.
alias – Keystore alias name, given in the ‘keytool’ command to create the keystore.
keystore – Path to the keystore file, which was created using the ‘keytool’ command.
storepass – Keystore password used while creating the keystore using ‘keytool’ command.

Hosting Multiple Domains In Tomcat

Tomcat allows us to host multiple domains in one instance, using multiple ' Host ' tags. In this article I will explain how to do it on Tomcat. This is very simple configuration using ' Host ' tags in your server.xml . A novice can also understand this configuration very easily. Before going into the details of the configuration first lets have a look at the ' Host ' tag, ' Context ' tag and ' Alias ' tags first. <Host name="domain1" appBase="[application base]" autoDeploy="[true/false]" unpackWARs="[true/false]"> <Alias>...</Alias> <Context path="" docBase="" reloadable="[true/false]"/> </Host> First lets have a look at ' Alias ' tag.

I tried to make the example as simple as possible, hope it helps those early birds. Example uses JSP to provide the pages with form where user can select the file to upload with other form fields, Commons File Upload API to process submitted form and read form fields separately, and Servlets as middle layer between JSP and Commons File Upload API, example also has ANT build script to generate the distributables. All the code can be downloaded, links to these resources are provided at the end of this post, lets get on with the example then. The flow in this example is as depicted in the following picture. As you can see, user selects the file to upload and provides normal form data as well, using "index.jsp" and submi...
