Applet Signing problem with singletons

Newbie & Debugging Questions
#1

Hi, I can sign my applets now and they work when I make small, 1 class programs. But when I make try to sign big applications or ones with Singleton classes it doesnt work. Does anyone know why?

#2

suggest using ‘ant’ to compile the jars, and then signing the whole jar. Never had any problems with it.

#3

thanks for the reply

I’m using Eclipse 3.4.1
Is the default jar builder ant? or do i have to change the exporter somehow / download a plugin?

#4

I haven’t actually signed any eclipse built jars directly,
antenna is really meant for J2ME but it’s handy to
create alternative builds.

Here’s an example of how I work with it, but I think some
feedback from people who sign jars straight off eclipse would be welcome also.

(ForceDel is a hack to delete the old junk from underneath, could be done cleaner)


<project name="Build jars" default="build_jar_applet" basedir=".">
<property name="output_dir" value="jars"/>
<property name="output_jar_udpclient" value="jars/udpclient.jar"/>
<property name="output_jar_udpserver" value="jars/udpserver.jar"/>

<target name="build_jar_udpclient">
	<mkdir dir="${output_dir}"/>
	<exec executable="utils/ForceDel.exe">
		<arg line="${output_jar_udpclient}"/>
	</exec>
	<jar jarfile="${output_jar_udpclient}">
	 	<fileset dir="bin/" includes="**/*.class"/>
		<fileset dir="../archon_common/bin/" includes="**/*.class"/>
	</jar>
	<signjar jar="${output_jar_udpclient}" alias="archon" storepass="secret" keystore="archon.keystore"/>
</target>

<target name="build_jar_udpserver">
	<mkdir dir="${output_dir}"/>
	<exec executable="utils/ForceDel.exe">
		<arg line="${output_jar_udpserver}"/>
	</exec>
	<jar jarfile="${output_jar_udpserver}">
	 	<fileset dir="bin/" includes="**/*.class"/>
		<fileset dir="../archon_common/bin/" includes="**/*.class"/>
	</jar>
	<signjar jar="${output_jar_udpserver}" alias="archon" storepass="secret" keystore="archon.keystore"/>
</target>

<target name="gen_keys">
	<genkey alias="archon" storepass="secret" keystore="archon.keystore">
		<dname>
		    <param name="CN" value="SNS Company Ltd."/>
		    <param name="OU" value=""/>
		    <param name="O"  value="slicksandslide.com"/>
		    <param name="C"  value="FI"/>
		  </dname>
	</genkey>
</target>
	
</project>

presume you’ve read http://www-personal.umich.edu/~lsiden/tutorials/signed-applet/signed-applet.html
Can you give more clues, error messages etc?
Maybe make a tiny test with 2 classes. I don’t remember a static class being forbidden explicitly…
