[Biojava-l] Problems for testing demos

[mark.schreiber at novartis.com]

The most likely answer is that the folder containing TestEmbl.class is not 
on your class path. Either that or you could put TestEmbl.class in your C:\Program Files\Java\jdk1.5.0_06\jre\lib\ext folder.

By the way, using the ext folder can cause problems if you have different 
versions of JAR files or files with conflciting names, however for testing 
it should be fine.

Dear all,

I  am new to Biojava. I install 
1) JDk on my Windows XP under c:\Program
Files\java\.....,
 2)  biojava.jar, bytecode-0.92.jar,
 commons-cli.jar,  commons-collections-2.1.jar
 commons-dbcp-1.1.jar, commons-pool-1.1.jar all under
c:\biojava folder. Then I go to >demos>seq and type
javac  TestEmbl.java I get some information on the
screen. After searching google  I put all *.jar files
into this folder:

C:\Program Files\Java\jdk1.5.0_06\jre\lib\ext

I compile the code again:

go to >demos>seq and type

javac  TestEmbl.java 

and I get a new file and looks like it works:

 TestEmbl.class

Then I type 

java TestEmbl

I get these infomration on the screen:

Exception in thread "main"
java.lang.NoClassDefFoundError: TestEmbl (wrong name:

        at java.lang.ClassLoader.loadClass(Unknown

        at
java.lang.ClassLoader.loadClassInternal(Unknown

I am not sure how to fix it. I search Biojava archies
but get no answers. Any idea will be aprreciated.
