Java SE (Java Platform, Standard Edition)

Hello Everybody,

I am building a project in Eclipse , using an ant build.
I used the Xlint Option , to determine the usage of deprecated API's.
I am building the project against JRE 1.5. I get the following compiler warnings
[javac] warning: [path] bad path element "C:\Views\snapshot\JRE5__cpnm2_0_proto.ntss\enm_herbie\framework\tools\external\jakarta-ant-1.5.1\lib\xalan.jar": no such file or directory

any idea as to why this is happening? what is that I need to chnage , in order to fix it ?

Thank you so much.
