Import an Ontology into JSP with Jesstaglib

[Stanley Lin]

Hi,nice to meet you.
I would like to import an ontology into JSP with Jesstaglib and apply
facts and rules of Ontology on JSP. first of all , I attempt to
download Jesstaglib software from Sourceforge website and use ant tool
trying install Jesstaglib. but the command line shows plenty of mistakes.
I don't know how to install Jesstaglib and import Ontology into JSP.
Who could help me solve this problem? thanks.

Sincerely,

[Martijn Verburg]

[Ulf Dittmer]

That looks like you're trying to build the tag lib - is that really necessary? Don't you have jar files that make up the taglib? In any case, in order to compile it you need to have the JSP libraries in your classpath - search for a file called jsp-api.jar. It's part of your servlet container; in Tomcat it's in TOMCAT_HOME/common/lib.

[Stanley Lin]

Dear all
Thank for your solution. I've been built the Jesstaglib program successfully and try some examples within Jesstaglib directory.
but I still don't know how to import plenty of instances of Ontology into JSP with Jesstaglib. Can everyone provide some
example code or give me some guide documents to me? Thanks.

Sincerely,

[William Brogden]

OK, I'm mystified - Ontology as a general term I am familiar with - you appear to be dealing with some very specific implementation. It would be a really big help if you could point to a good source on this implementation.

"Import an Ontology" is just gibberish without details on the tools you are trying to use.

Bill

[Stanley Lin]

To Dear Friends
I am so sorry using the wrong word "import" . as a matter of fact , I would like to embed
the Ontology into JSP with Jesstaglib pattern. but I don't know how to embed.
Can anyone teach me how to do for next step or give me some code samples.
Thanks.
Sincerely,
