RE: JSON Property
Hello,
I'm trying to use this combination of tags to convert to JSON, but it seems I have some problems with the TLD. I'm getting the following error:
manageDocuments.jsp:2:5: No tag library could be found with this URI. Possible causes could be that the URI is incorrect, or that there were errors during parsing of the .tld file.
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
Which is the correct url? and I suppouse I need the jar that implements the tags, right?where can I find the it?
Thanks
Jose Luis

That was the problem. I hadn't included the jstl library. It works fine now. Thanks!!

The right url should be http://java.sun.com/jsp/jstl/core,
http://java.sun.com/jstl/core is the old one.
Did you include the jstl library?

RE: JSON Property
Posted by Jose Luis Martinez Avial <jl...@pb-santander.com>.
never mind, it can be avoided with the attribte escapeXml='false' in the tag.

Subject: RE: JSON Property
Question, the tag is writing the quotes as ", so I'm getting something like this:
var distributionListContent = {"identifier":"idDistributionList","items":[{"dateCreated":"2011-01-08T15:38:25","distributionListName":"EDP\/SPR","idDistributionList":"3"}],"label":null};
How can I avoid that?

The right url should be http://java.sun.com/jsp/jstl/core,
http://java.sun.com/jstl/core is the old one.
Did you include the jstl library?

RE: JSON Property

Question, the tag is writing the quotes as ", so I'm getting something like this:
var distributionListContent = {"identifier":"idDistributionList","items":[{"dateCreated":"2011-01-08T15:38:25","distributionListName":"EDP\/SPR","idDistributionList":"3"}],"label":null};
How can I avoid that?

Re: JSON Property
Posted by Maurizio Cucchiara <ma...@gmail.com>.
The right url should be http://java.sun.com/jsp/jstl/core,
http://java.sun.com/jstl/core is the old one.
Did you include the jstl library?

Hello,
I'm trying to use this combination of tags to convert to JSON, but it seems I have some problems with the TLD. I'm getting the following error:
manageDocuments.jsp:2:5: No tag library could be found with this URI. Possible causes could be that the URI is incorrect, or that there were errors during parsing of the .tld file.
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
Which is the correct url? and I suppouse I need the jar that implements the tags, right?where can I find the it?
Thanks
Jose Luis

RE: JSON Property
Posted by "Biesbrock, Kevin" <Bi...@aoins.com>.
I google searched "jstl" and clicked on the first link to find:
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>

Subject: RE: JSON Property
Hello,
I'm trying to use this combination of tags to convert to JSON, but it seems I have some problems with the TLD. I'm getting the following error:
manageDocuments.jsp:2:5: No tag library could be found with this URI. Possible causes could be that the URI is incorrect, or that there were errors during parsing of the .tld file.
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
Which is the correct url? and I suppouse I need the jar that implements the tags, right?where can I find the it?
Thanks
Jose Luis
