jstl + string
hello, has anyone used the jstl along with apache's string tag library. I can't seem to get them to work together. Independently they both work fine, but when I add the string tag library to my jsp application which is using jstl, and go to the page which utilizes the string tag library i get: org.apache.jasper.JasperException: org/apache/commons/lang/NumberUtils What am I doing wrong? Has anyone gotten these two to work together. Thanks

From this error report I'd say that you don't have the Apache Jakarta
Commons Lang jar downloaded, it's a dependency of the String Taglib from
1.0 onwards.
Additionally, the current nightly build of the String Taglib ought to
interact a lot better with JSTL in that it should understand ${foo} EL
variables etc. The nightly build has an important bugfix to do with using
string tags inside loops as well.

RE: FW: String TagLib 1.0 wordWrap StringIndexArrayOutOfBoundsException(Bug#15321)
Okay, was an odd bug :) It occured on the 80th, 155th, 259th, 497th, 591st... element. Which might just be dependent on the random string i was throwing into it. Anyways, I've protected against it, and after I commit it'll go into tonight's nightly build. I've only tested the underlying Java util class, but it's there where the real bug is. The taglib should reflect the fix fine. wordWrap is one of those methods I know I should have done with far more beauty, but it's managed to evolve to pretty much do what it's meant to. I overestimated the pain of this bug I think :) Let me know if this fixes things for you tomorrow, Hen On Tue, 28 Jan 2003, Robert Taylor wrote: No worries.

How do tag libraries handle final references to specific images used in custom tags?
I'm familiar with the HTML tags for specifying images, either as a static image or as a button. I'm also familiar with how tag libraries work. What are useful conventions for building custom tags in a tag library that come with canned images? For instance, if a tag library provides some sort of tags which allow the user to specify moving forward and backward in a list, and the tag library provides the default images to use for the arrows, what provisions are commonly made for referencing the images from the generated HTML (or any other references)? Is there any history of making the generated HTML reference a servlet (or Struts action) with an attribute specifying an image name, and having the servlet stream the image from the classpath? If this is a reasonable strategy, what are issues/tradeoffs with this approach? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
