Subject Re: TOmcat5.5.17 - jasper-runtime.jar ERROR
Date Mon, 04 Sep 2006 14:46:46 GMT
There *was* an outstanding bug where someone tried to cast a Vector to List
and then to solve the org.apache.jasper.runtime.JspSourceDependent.getDependants() 
method signature was then downcasted to return Object (instead of the original List)

More info is available at

I would suggest following up on the bug

Subject: TOmcat5.5.17 - jasper-runtime.jar ERROR



We have recently migrated from Tomcat 5.0.28 to Tomcat 5.5.17


In our component build we pre-compile all jsp files. 

However after changing to Tomcat5.5 the Jsp Pre-Compilation fails and
throws the following ERROR:


/view/sarag-latest-cct-ccm/vob/ccm/Projects/car/jsp_files/MAMgrSearch_js org.apache.jsp.MAMgrSearch_jsp is not abstract and does not
override abstract method getDependants() in

    [javac] public final class MAMgrSearch_jsp extends

    [javac]              ^

/view/sarag-latest-cct-ccm/vob/ccm/Projects/car/jsp_files/MAMgrSearch_js getDependants() in org.apache.jsp.MAMgrSearch_jsp cannot

    [javac] required: java.util.List

    [javac]   public Object getDependants() {

    [javac]                 ^

    [javac] Note: Some input files use unchecked or unsafe operations.

    [javac] Note: Recompile with -Xlint:unchecked for details.

    [javac] 100 errors


It looks like the files generated using JspC from
jasper-compile.jar is generating getDependants() method with signature:

List getDependants();


However the new jasper-runtime.jar expects a signature of the type:

Object getDependants();


Jasper-compiler.jar & jasper-runtime.jar are included in the class path
while compiling.


Is this a know issue? If yes, is there a work around for the same. 

Any help would be appreciated.


Thanks & Regards
