Hi,
I am running files reading java class but encountered error:
java.lang.ClassNotFoundException

Is there a way to overcome this error? I am new to using java in linux.

Thanks for any help in advance.

Regards
Michelle

sure, there is a way, but we need more info. At least the full error message, but would be better to explain something about your source files also.

Hi

I am attaching file with error message so it makes clearer what the problem is. Also info on java jdk that I have installed on linux. Hope to get more detail info on how to overcome this problem.

Thanks

Obviously no JAVA_PATH or CLASS_PATH are present in your environment.

Try manually setting them.

Tried setting Classpath & Java-Home as below, the same errors still appear. Hope can get some help on overcoming it. Thanks.

export CLASSPATH=/home/tools/opennlp/maxent/
export JAVA_HOMe=/usr/bin/java

if you have got the same error your CLASSPATH is still not set correctly. You would better read some documents on it (how to set up a java environment) . Maybe you need to download/install some packages also. Unfortunately the information you gave is not sufficient to solve it from here.
