Jserv Compiling error

[Liang, Daisy]

Hi there :

I have an application using ApacheJServ/1.0,  The testing file hello.jsp works fine.  When needs to bring up application's first page,  it comes out these 2 errors :

--------------------------------------------------------------------------
Error compiling source file: file:/web.tst.sys/htdocs.insite/apps/filecabinet/enterfilecabinet.fc builtin-javac -classpath /opt/java/lib/classes.zip:.:../JSDK2.0/lib/jsdk.jar:../lib/ApacheJServ.jar:../lib/classes111.zip:/web.tst.sys/jserv/filecabinet/servlet:../lib/javaxservlejsp.jar -d /web.tst.sys/tmp -deprecation -encoding 8859_1 /web.tst.sys/tmp/jsp__apps__filecabinet__enterfilecabinet_2ejsp.java /web.tst.sys/tmp/jsp__apps__filecabinet__enterfilecabinet_2ejsp.java:17: Cyclic class inheritance or scoping. public class jsp__apps__filecabinet__enterfilecabinet_2ejsp extends org.gjt.jsp.HttpJspPageImpl{ ^

 2 errors
------------------------------------------------------------------------------------

no errors in the log files (jservctl.log   httpdctl.log).    Same source code runs well in other Environment ( using  ApacheJServ/1.0 too),  don't understand what is this Cyclic class inheritance or scoping  problem , where can I find this  org.gjt.jsp.HttpJspPageImpl ? 

Any tip or hint is appreciated.

Thanks
