Hi, guys, I'm a beginner of JAVA developing. I download the JCad source codes and try to test. Now some problems occur. First, I have read such files carefully: README INSTALL DOCS/hacking.txt DOCS/userguide.txt But I cannot find the file "JCad.jar". So I have to compile the sourcecodes on myself. First step, I compile them with JDK 1.2.2. I found that SAX classes are missing, so I download SAX2.0 from the official SAX website. Henceforth, I've got the JCad.class. Second, I try to run it as follows: ########################################################## C:\JCad>java org/jcad/JCad/JCad uncaught exception: java.lang.NullPointerException java.lang.NullPointerException at org.jcad.JCad.JCad.main(JCad.java:224) ########################################################## I found that JCad.java:224 is as follows: frame.getContentPane().add("Center", new JCad()); Can you do me a favor to help me out? Thanks in advance. /PowerGIS ______________________________________ =================================================================== ÐÂÀËÃâ·Ñµç×ÓÓÊÏä (http://mail.sina.com.cn) ÐÂÀË·ÖÀàÐÅÏ¢:·ÖÀàÐÅÏ¢ Ë´¦µß·å?
