Webapps for i-Jetty

Question

Hello,

Has anyone created an app for i-Jetty? I'm trying to get started using it but I don't understand what I need to do to create the .war file. When using the dx tool to change my .class files to .dex I get an

UNEXPECTED TOP-LEVEL EXCEPTION: java.lang.RuntimeException:\...\ijetty\hello\HelloWorld.class: file not found
at com.android.dx.util.FileUtils.readFile(FileUtils.java:55)

at com.android.dx.command.dexer.Main.main(Main.java:120)
at com.android.dx.command.Main.main(Main.java:89)
1 error; aborting

Is the code section usually difficult to format correctly? Took me 10 minutes to fix this small block...

I know I need to convert my class files to .dex and my libs, then convert to .war

If anyone could guide me out here I would greatly appreciate it!

Thanks, Chris

I had created a maven build file for i-jetty webapps some time back. Following is the directory structure of the webapp sources:

 sampleapp/
  |-- pom.xml
  `-- src
      `-- main
          |-- java
          |   `-- {java sources}
          `-- webapp
              |-- {html js css sources}
              `-- WEB-INF
                  `-- web.xml

On the command line export two environment variables:

  $>export ANDROID_HOME=/path/to/android/sdk
  $>export ANDROID_PLATFORM=7 OR 8 or whatever platform you are using

After you have done that, type: (Assumes that you have maven 2.1+ installed)

  $>mvn package

This will generate the sampleapp.war file in the target directory. Which can be deployed in i-jetty. Below is the pom.xml. Change the artifactId and name in pom.xml to suit your needs.
