texte = Okay, now that the engine is loading the java VM libs, there are a couple other issues to consider. First, your JavaClassPath pref should contain all the paths needed for your java class/jar files. In your case, it seems that the path is setup correctly. Second, the [Object] context can only call Java methods that fit this particular 'signature' (prototype):public static String MyJavaFunction(String[] args, int []type)So this should work... public class WebDNAJava{ public static String TestMethod(String []args, int []type) { return Hello from java!!!!!!!!; } }And in your tpl file.... [object objname=WebDNAJava&call=TestMethod&type=1&classpath=][/object] Also, the method you are trying to call can not be the 'main' method.In some cases the method you wish to invoke may not 'fit' that prototype. In that case, you can create a new java method that acts as a 'middle man'. So the [object] context would call your 'middle man' method, and you 'middle man' method would then call the desired method.> -----Original Message----- > From: WebCatalog Talk > [mailto:WebDNA-Talk@talk.smithmicro.com]On Behalf > Of Sage Hobbs > Sent: Friday, September 20, 2002 1:32 PM > To: WebCatalog Talk > Subject: Re: Has ANYONE gotten the [object] context to work with Java > (OSX) ???
