Re: digest.txt.sig problem

If you are using Getdown as an applet, you need to generate a signature file which binds your signed applet to a particular application URL otherwise someone could use your signed Getdown applet to download and install their own software while impersonating yourself or your company. That would be bad. :)

When you invoke the digester to generate your digest.txt file, you need to pass information about the same keystore you use to sign the getdown applet .jar file. For example:

    <taskdef name="digest" classname="com.threerings.getdown.tools.DigesterTask">
      <classpath>
        <pathelement path="${deploy.dir}/lib/commons-codec.jar"/>
        <pathelement path="${deploy.dir}/lib/getdown.jar"/>
        <pathelement path="${deploy.dir}/lib/samskivert.jar"/>
      </classpath>
    </taskdef>
    <digest appdir="${app_dir}" keystore="${sign.keystore}" alias="${sign.alias}"
            storepass="${sign.storepass}"/>

In this case:

app_dir is set to the directory containing your application
sign.keystore is set to the path to your keystore
sign.alias is your signing key alias
sign.storepass is the keystore password

Re: digest.txt.sig problem

The code I showed you above will generate the digest.txt file *and* the digest.txt.sig file.

Re: digest.txt.sig problem

Eclips tell me that the com.threerings.getdown.tools.DigesterTask class cannot be found. This is my ant code:


    <taskdef name="digest" classname="com.threerings.getdown.tools.DigesterTask">
      <classpath>
        <pathelement path="lib/commons-codec.jar"/>
        <pathelement path="getdown-retro-pro.jar"/>
        <pathelement path="lib/samskivert.jar"/>
      </classpath>
    </taskdef>
    <digest appdir="1/" keystore="***" alias="***"
            storepass="***"/>

Whats wrong ??

Re: digest.txt.sig problem

When I use code like this gives me the same error.


    <taskdef name="digest" classname="com.threerings.getdown.tools.DigesterTask">
      <classpath>
        <pathelement path="${deploy.dir}/lib/commons-codec.jar"/>
        <pathelement path="${deploy.dir}/getdown-retro-pro.jar"/>
        <pathelement path="${deploy.dir}/lib/samskivert.jar"/>
      </classpath>
    </taskdef>
    <digest appdir="${deploy.dir}/1/" keystore="***" alias="***"
            storepass="***"/>

Re: digest.txt.sig problem

The jar files in the classpath section need to actually point to real jar files. So make sure those jar files exist at the paths that are specified.

Re: digest.txt.sig problem

Here on my hard disk I have whole getdown script:

C:\Documents and Settings\MARCIN\projekty\Projekty jME\getdown

How schould I write the paths in my ant script (getdown-retro-pro.jar and getdown-pro.jar are iC:\Documents and Settings\MARCIN\projekty\Projekty jME\getdown\lib the same as commons-codec.jar and samskivert.jar)

TIA

Re: digest.txt.sig problem

Make a "lib" directory in the same directory that you have your build.xml file. Then copy into that lib directory the commons-codec.jar, getdown-retro-pro.jar and samskivert.jar files from the other getdown directory on your harddrive.

Then change the build script to use:

        <pathelement path="lib/commons-codec.jar"/>
        <pathelement path="lib/getdown-retro-pro.jar"/>
        <pathelement path="lib/samskivert.jar"/>

and it should find the jar files that it needs to generate the digest.txt file.
