I Got a source code which has a row: import ag.*; now I got a jar file(ag.jar) which should contain all the classes in ag-package. Tried to get them in the project through configure\options\jdkprofile\j2sdk1.4.03\edit->add archive->ag.jar from directory. Do I need the row import ag.*; still? I think i do not. When compiling, it gives a error message that package ar dosn't exist, which I think is correct. But still the compiler canot recognize the classes sopposedly under ag.jar. When I try to extract the files from ag.jar(to get the source code package) (jar xf ag.jar)I get error message java.lang.IllegalArgumentException at java.util.Zip.zip.ZipInputStream.getUTF8String, how should I interpret that? Does someone know how could i Examine what in jar-file? or alternatiely have I done something wrong in includin the ag.jar file, is there something else I shoul do there....? thanks for your time.

says still package ag doesn't exist, liked to see what's in the ag package, but it I try to examine it in command prompt with: jar tf ag.jar it gives error message like: META-INF/ META-INF/MANIFEST.MF java.lang.IllegalArgumentException at java.util.zip.ZipInputStream.getUTF8String(ZipInputStream.java:284) at java.util.zip.ZipInputStream.readLOC(ZipInputStream.java:237) at java.util.zip.ZipInputStream.getNextEntry(ZipInputStream.java:73) at sun.tools.jar.Main.list(Main.java:736) at sun.tools.jar.Main.run(Main.java:192) at sun.tools.jar.Main.main(Main.java:904) Still wondering why it does'n find ag package. Is it possible that there isn't package ag under ag.jar-file?
