Hi,

We have one very old application which is running on Tomcat3.2. We have modified one of the JSP file(wb.jsp) recently and after that we started getting below error during loading of application but the error disappeared if we revert back the original file. Then we found that Tomcat is using old compiled file from 'work' folder becuase if we clean up 'work' folder of Tomcat then also we are getting below compile exception.We also verified physical location of rwptaglib.tld file.


Could you please let me know the root cause of this issue.

Thanks,
-Bikash

I suspect that the TLD file has a URL in it that points to a defunct website.

Hi,

Thanks!!!

The below mentioned URL in the rwptaglib.tld file doesn't exists anymore.



They changed the DTD file name to "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd"

So compilation exception disappeared after modification in the name of DTD file.

Thanks,
-Bikash
