Java Forum / First Aid / February 2006myjavaserver and JAR files
Does anyone know whether or not myjavaserver.com allows for storage and utilization of JAR files? I need to be able to import tcl.lang.* within one of my classes and have no ability to do so (keep getting NoClassDefFoundError tcl/lang/TclException. Do I need to create a /tcl/lang folder and place the JAR file in it for it to work? What do you advise?

If I remember correctly (forgot my password so can't check), all your classes need to be in a package name starting with your account name. So either ask to have the TCL libraries added, or rename them somehow. Come to think of it, you could use URLClassLoader.newInstance to load the libraries, but you would need all your code that uses TCL to be loaded by the same class loader.

You would need to create one instance (with URLClassLoader.newInstance), which would load all of the TCL library and all of your code that uses it. I've not tried it, so I can't be sure myjavaserver permits the technique. Tom Hawtin SignatureUnemployed English Java programmer http://jroller.com/page/tackline/ > > How would I use URLClassLoader?

So I would have a "wrapper class" that would have URLClassLoader.newInstance that would load the TCL library, code, etc. Or would I have, in my original class (in this case, HTMLParser), a URLClassLoader.newInstance that loads the TCL libraries, etc.? Assuming I do not import, would I have to call any classes via tcl.lang.* like URLClassLoader.newInstance(); //... tcl.lang.Interp interp = new tcl.lang.Interp(); Phil > Tom Hawtin > -- > Unemployed English Java programmer > http://jroller.com/page/tackline/ Free MagazinesGet these publications absolutely FREE for up to 12 months.
