Most of my tags are done with .tag files, as its much easier to work with html that way. However, my web applications expect these tags in the web.xml/tags directory, which is a pain when a tag is shared among multiple web apps.

If i understand correct, a java tag class that extends TagSupport can include the tld in the source code, and the tag can be imported easily. Can I do something like that for my .tag files so I can keep them in a shared parent project an开发者_StackOverflowd not worry about copying them to individual tag folders in my web applications? Is there a way for a tld to point to a .tag file on the classpath?


This page says:

Tag files can be placed in one of two locations: in the /WEB-INF/tags/ directory or subdirectory of a web application or in a JAR file (see Packaged Tag Files) in the /WEB-INF/lib/ directory of a web application. Packaged tag files require a tag library descriptor (see Tag Library Descriptors), an XML document that contains information about a library as a whole and about each tag contained in the library.

and

Tag files can be packaged in the /META-INF/tags/ directory in a JAR file installed in the /WEB-INF/lib/ directory of the web application. Tags placed here are typically part of a reusable library of tags that can be used easily in any web application.

Tag files bundled in a JAR require a tag library descriptor. Tag files that appear in a JAR but are not defined in a TLD are ignored by the web container.

When used in a JAR file, the path subelement of the tag-file element specifies the full path of the tag file from the root of the JAR. Therefore, it must always begin with /META-INF/tags/.
