Trying to execute a program, I get the following error: Exception in thread "main" java.lang.NoClassDefFoundError: " whenever I set up my CLASSPATH. export classpath=/opt/oracle/product/9.2.0/jdbc/lib/ojdbc14.jar:/opt/oracle/product /9.2.0/jdbc/lib/nls_charset12.zip javac Test.java ==> ok javaTest == > Exception in thread "main" java.lang.NoClassDefFoundError: " This is a CLASSPATH problem because if unset the classpath, I don't get any error. So it has nothing to do with the code in my program. I am using jdk 1.4.1_01 and the jdbc driver is thin (included with Oracle 9i).
Perhaps you need to include the current working directory in your CLASSPATH setting. The current working directory is denoted with a period. So, your CLASSPATH should be .:[OTHER LOCATIONS HERE] [ June 29, 2003: Message edited by: Dirk Schreckmann ]
you need to ser the classpath of your system to include the jar files in JDK. just write on the command prompt set CLASSPATH=e:\jdk1.4\lib\nameofJar.jar;%CLASSPATH%;.; where e:\jdk1.4 (is your java_home) and nameofJar is name os jar files in lib directory under java_home. Include all the jar files one by one. it will work for you. If everything goes well. Modify the classpath settings and reopen a new command prompt.
