Struts Tag Libraries / NoSuchMethodException

[sdupont73]

I'm just getting struts 1.1 up and running with Tomcat 5.0. Tomcat is running fine. I am attempting to use the Struts Logic Tag Library by adding :

<%@ taglib uri=&quot;/WEB-INF/struts-logic.tld&quot; prefix=&quot;logic&quot; %>

... to the top of my jsp. I have my tld files in the correct place as shown above. I have all the struts jars in my classpath. My application is up and running fine. However, as soon as i add the tag library include and reload my jsp, I get a NoSuchMethodException:

It appears that Jasper is trying call a 2-String constructor of javax.servlet.jsp.tagext.TagAttributeInfo. However, I have looked at the jasper source and it specifically calls the appropriate 5 param ctor. I am utterly baffled by this out-of-nowhere exception.

I am wondering if anyone else has encountered this problem and the steps they took to solve it.

Thanks in advance

Hi,

Did you add the tld in web.xml ?

Cheers,

Yes, the tlds are correctly in place.

After looking at this more carefully, I begin to suspect that TagLibraryInfoImpl.createAttribute() IS actually calling the 5 param constructor. Upon careful examination ...

java.lang.NoSuchMethodError: javax.servlet.jsp.tagext.TagAttributeInfo.<init>(Ljava/lang/String;ZLjava/lang/String;ZZ)V

... the 'Z's actually probably represent boolean params. The ctor, thus takes as params: a String, a boolean, String, boolean, boolean. In fact, this is just the constructor that TagAttributeInfo has. I now therefore suspect that somewhere in my set of libraries is an older version of that class that superceded the one I know exists in the most recent servlet.jar. Do you concur?

Thanks.

I was having the same problem after upgrading my JBoss 3.2.3 server configuration from Tomcat 4.x to 5.0.x.

I had copied the /jboss-3.2.3/docs/examples/tomcat/jbossweb-tomcat50.sar to my server configuration without using the build script they provide (same directory: build-tc5-config.xml).

The important step that was missed as a result of my copying by hand was that the javax.servlet.jar should not be under your /jboss-3.2.3/server/<you configuration>/lib directory when using Tomcat 5.0.x. So I just whacked it and now everything is fine!
