Using Guava with GWT

Could someone tell me what I need to do to enable Guava support in GWT. I have downloaded Guava R07 and in there there are the following two files: - guava-r07.jar - guava-r07-gwt.jar I have a few questions regarding this: - Where do these files go? I am guessing that the standard Jar is made available to my IDE for coding, and that both are made available to the GWT compiler for building the JavaScript? - Do I need to add all the .gwt.xml files from the -gwt.jar into my project's main gwt.xml file or only the portions I need? - There are other Jars on the trunk of the Guava&GWT project (ie not in the download, such as one for jsr305) which I think I may need, but I'm not sure. Sorry, normally I don't have trouble with this kind of thing, but I can't quite work out what goes where. FYI I'm using GWT 1.6 for the time being, but am hoping to move to 2 soon. If Guava isn't compatible with 1.6 that is not a problem. Update I have the following files in a folder called gwtlib: - guava-r07-gwt.jar - guava-r07.jar - jsr305-1.3.9.jar And my Ant script does the following: ``` <path id="project.class.path"> <fileset dir="gwtlibs" includes="guava-r07.jar"/> <fileset dir="gwtlibs" includes="guava-r07-gwt.jar"/> <fileset dir="gwtlibs" includes="jsr305-1.3.9.jar"/> <pathelement location="${gwt.sdk}/gwt-user.jar"/> <fileset dir="${gwt.sdk}" includes="gwt-dev*.jar"/> </path> <target name="gwtc"> <java failonerror="true" fork="true" classname="com.google.gwt.dev.Compiler"> <classpath> <pathelement location="app"/> <path refid="project.class.path"/> </classpath> <jvmarg value="-Xmx256M"/> <arg value="-localWorkers"/> <arg value="2"/> <arg value="-war"/> <arg value="gwt-public"/> <arg value="Main"/> </java> </target> ``` Running the above command, I get the following errors: - Errors in 'jar:file:///project/gwtlibs/guava-r07-gwt.jar!/com/google/common/collect/Constraints.java' - Line 254: The method subList(int, int) is undefined for the type List Without the jsr jar on the classpath, I get the following errors: - The import javax.annotation cannot be resolved - Nullable cannot be resolved to a type Thanks Rich
