Unable to run helloWorld Struts web app on Tomcat 5.5 with Eclipse and Maven

please let us know which version of struts you are using and also provide web.xml and also the path structure where you are keeping the tlds?

hi

struts-tags.tld is not anywhere in my project. i never explicitly included it and i supposed that it wasn't pulled-in from anywhere. the only two things i specifically added to my eclipse project were: struts2-code-2.1.8.jar and xwork-core-2.1.6.jar from the struts-2.1.8/ lib directory

i looked at http://forums.sun.com/thread.jspa?threadID=5361407 but it didn't address my problem which i suspect is that struts-tags.tld is missing completely. where can i find it and include it?

i looked for it under the whole linux struts-2.1.8/ directory hierarchy with:
"find struts-2.1.8/ -name struts-tags.tld -print"
but the search didn't yield any results.

i also looked for it in the workspace using the  the IDE's Search utility with the follwoing pattern but nothing found there either:  struts*.tld

also notice, in the attached image which also shows struts.xml that the Java Resources tree is marked as having an error but if the tree-views are expanded the error is not visible anywhere further down the tree hierarchy

please look at attached image for IDE image and web.xml

You need to have struts.jar in class path. I didn't find the same. Please include in the classpath and try.

the latest struts (2.1.8 at least) no longer have struts.jar. now there are multiple jar files that contain the various resources

tnx

1.The minimum set of libraries you must include in your application:
-struts2-core.jar
-xwork.jar
-ognl.jar
-freemarker.jar
-commons-logging.jar
-commons-fileupload.jar
-commons-io.jar

2. The struts-tags.tld is located in the META-INF folder within struts2-core.jar.

You have also to include in the web.xml file:

<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>        
</filter>

<filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

hi ioanton

thanks for the advice but that doesn't work

the IDE was still complaining that it couldn't find the tld so i extracted it from struts2-core-2.1.8.jar and imported it into the project's META-INF folder and changed the jsp to point to it:
<%@ taglib prefix="s" uri="META-INF/struts-tags.tld" %>


i also added the directives you mentioned in web.xml but now get a different problem:
this is out of Eclipse's  server Console:
Exception starting filter struts2
ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

then a stack trace follows and finally:
05-Nov-2009 20:53:05 org.apache.catalina.core.StandardContext start
SEVERE: Error filterStart

i think there's something wrong with my install.
it's as if the classes and resources in my jars are not being detected in full. that is perhaps why the tld is being missed in the first place although it's in the struts2-core-2.1.8.jar

which is funny cause i just use the IDE to add them

thnx for any help

Make sure the whole set of libraries is located in the WebContent/WEB-INF/lib folder. You don't need to extract the struts-tags.tld from its jar file. The framework finds it automatically.
I don't see in your screenshot the struts.xml file. It must be located in the src directory, and will end up in the WEB-INF/classes folder after deployment.

the IDE won't allow me to drag and drop the libary files in WebContent/WEB-INF/lib folder
neither will it let me move the struts.xml out of WEB-INF/lib

?????

Change the view by selecting Window->Show View->Navigator menu items. This view lets you organize the directory structure as you want.

nope.

managed to move the struts.xml but the jars aren't visible to drag and drop.

also cant run the app without having the tld hard-wired to its external location on the filesystem.

either way i get the error:
org.apache.jasper.JasperException: /index.jsp(8,12) Unable to load tag handler class "org.apache.struts2.views.jsp.PropertyTag" for tag "s:property"

Can you show me the content of the file index.jsp?

<%@ taglib prefix="s" uri="WEB-INF/struts-tags.tld" %>

<html>
    <head>
        <title>Hello World!</title>
    </head>
    <body>
        <h2><s:property value="message" /></h2>
    </body>
</html>

Replace the first line with:

<%@ taglib prefix="s" uri="/struts-tags" %>

i did, but the the IDE then underlines the URI as undetectable and the compiler/deployer then complains also... :(

i ended up importing the jars from the project's Properties->Add external jars dialog BUT then I ALSO had to manually copy them to the WebContent/WEB-INF/lib folder as you had suggested. It kind of works now although i have yet to see Hello World on my screen...

thanks for your help
