Re: Access jar files in a library directory in the jar file

[Raja Nagendra Kumar]

Hi, http://docs.oracle.com/javase/tutorial/deployment/jar/downman.html If you want to load classes in MyUtils.jar into the class path for use in MyJar.jar. These two JAR files are in the same directory and can't be packaged within MyJar.jar Regards, Nagendra Raja Nagendra Kumar Founder & C.T.O Mobile: +91-9886723872 Email: nagendra.r...@tejasoft.com IM: nagendra.raja (Skype)  http://in.linkedin.com/in/nagkumar TejaSoft Innovations Pvt Ltd Factor 4 Results See who we know in common Want a signature like this?  On 6/18/2013 4:38 AM, Joe Attardi wrote: Hi Rob, I don't think you can have JAR files inside the JAR file like that.

My problem is that Java does not seem to be able to find the libraries. I get this message when I try to run the jar file: java -jar LibraryAlmaInterface.jar Exception in thread "main" java.lang.NoClassDefFoundError: org/linfield/PreferencesManager/XMLPrefs at org.linfield.Library.PatronDataTransfer.<clinit>(Unknown Source) Caused by: java.lang.ClassNotFoundException: org.linfield.PreferencesManager.XMLPrefs at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 1 more You can see from the table of contents that the c;ass file is there: jar tf LibraryAlmaInterface.jar META-INF/ META-INF/MANIFEST.MF lib/ org/ org/linfield/ org/linfield/Library/ org/linfield/Library/Workers/ lib/jsch-0.1.49.jar lib/linfield.jar lib/log4j-1.2.15.jar lib/xerces.jar org/linfield/Library/CalculateBarcode.class org/linfield/Library/PatronDataTransfer.class org/linfield/Library/Workers/MyUserInfo.class org/linfield/Library/Workers/PatronLoadsXML.class org/linfield/Library/Workers/SecureFTPHandler.class And the linfield.jar contains the class that the loader can't find: META-INF/ META-INF/MANIFEST.MF org/ org/linfield/ org/linfield/PreferencesManager/ org/linfield/PreferencesManager/PreferencesParser.class org/linfield/PreferencesManager/XMLPrefs.class org/linfield/PreferencesManager/XMLPrefs.java org/linfield/PreferencesManager/PreferencesParser.java And the manifest in linfield.jar is: cat META-INF/MANIFEST.MF Manifest-Version: 1.0 Created-By: 1.4.0 (Sun Microsystems Inc.) And most importantly, here is the main MANIFEST.MF file (for LibraryAlmaInterface.jar): cat META-INF/MANIFEST.MF Manifest-Version: 1.0 Ant-Version: Apache Ant 1.8.3 Created-By: 1.6.0_45-b06-451-11M4406 (Apple Inc.)

Any help would be greatly appreciated. Thanks, Rob Tanner Linfield College
