hi, i'm trying to get idl to execute some java (my language may betray that i'm a java newbie). i'm using a pre-made idl routine that should be calling some java "stuff" (methods? classes?). my fingers were crossed that it would work straight away, but i got this strange looking java stack trace. so i went to the java examples that come with idl, as a launching point to understand things. at this point, something weird happened. i ran hellojava fine. then i tried to run hellojava2 and got the following error: IDL> hellojava2 % ERR -ReflObject::doesClassExist exc:null % java.lang.InternalError % at java.util.zip.Inflater.init(Native Method) % at java.util.zip.Inflater.(Inflater.java:75) % at java.util.zip.ZipFile.getInflater(ZipFile.java:375) % at java.util.zip.ZipFile.getInputStream(ZipFile.java:320) % at java.util.zip.ZipFile.getInputStream(ZipFile.java:286) % at java.util.jar.JarFile.getInputStream(JarFile.java:387) % at sun.misc.JarIndex.getJarIndex(JarIndex.java:92) % at sun.misc.URLClassPath$JarLoader.(URLClassPath.java:547) % at sun.misc.URLClassPath$3.run(URLClassPath.java:324) % at java.security.AccessController.doPrivileged(Native Method) % at sun.misc.URLClassPath.getLoader(URLClassPath.java:313) % at sun.misc.URLClassPath.getLoader(URLClassPath.java:290) % at sun.misc.URLClassPath.getResource(URLClassPath.java:160) % at java.net.URLClassLoader$1.run(URLClassLoader.java:192) % at java.security.AccessController.doPrivileged(Native Method) % at java.net.URLClassLoader.findClass(URLClassLoader.java:188) % at java.lang.ClassLoader.loadClass(ClassLoader.java:306) % at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:268) % at java.lang.ClassLoader.loadClass(ClassLoader.java:251) % at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) % at java.lang.Class.forName0(Native Method) % at java.lang.Class.forName(Class.java:164) % at com.rsi.javab.ReflObject.doesClassExist(ReflObject.java:601) % Class helloWorld not found % Execution halted at: HELLOJAVA2 19 /usr/local/itt/idl/resource/bridges/import/java/examples/hellojava2.pro % $MAIN$ this error is very similar to the error i got when trying to run my out-of-the-box java from before (the last 10 lines were exactly the same). then i tried some of the other example programs, and after running those successfully i went back to try hellojava2.pro and it worked (after a recompile...didn't try it without). so does this error look familiar to people? any guidance would be appreciated. gh
