How can I export a .tld file from a jboss-module?

[michele.mazzei]

Hi to all,

I'm trying to port a spring-mvc based war to jboss AS7.

I've done the following steps:

1. I created a spring module as below:

<module xmlns="urn:jboss:module:1.1" name="org.springframework">

    <resources>

....

       <resource-root path="spring-context-support-3.2.0.RELEASE.jar"/>

....

            <resource-root path="spring-webmvc-3.2.0.RELEASE.jar"/>

....

    </resources>

    <dependencies>

          <module name="org.jboss.vfs" export="true"/>

          <module name="javax.servlet.api" export="true"/>

          <module name="javax.servlet.jsp.api" export="true"/>

          <module name="javax.servlet.jstl.api" export="true"/>

        <module name="javax.api" export="true"/>

        <module name="org.apache.log4j" export="true"/>

        <module name="org.antlr" export="true"/>

        <module name="org.dom4j" export="true"/>

        <module name="org.hibernate" export="true"/>

        <module name="javax.persistence.api" export="true"/>

        <module name="org.javassist" export="true"/>

        <module name="org.jboss.logging" export="true"/>

        <module name="javax.transaction.api" export="true"/>

    </dependencies>

</module>

2. I deployed my springmvc based application in a WAR using the following deployment structure:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">

          <deployment>

                    <dependencies>

                              <module name="com.h2database.h2" />

                              <module name="org.codehaus.jackson.jackson-core-asl" />

                              <module name="org.codehaus.jackson.jackson-mapper-asl" />

                              <module name="org.slf4j" />

                              <module name="org.springframework">

                                        <imports>

                                                       <include path="META-INF**" />

                                                       <include path="org**" />

                                        </imports>

                              </module>

                    </dependencies>

          </deployment>

</jboss-deployment-structure>

The problem is that it does not work because the jsp pages cannot read the tld (tag libraries) include in spring-mvc.jar and located under META-INF directory.

I declared to include all files under META-INF directory:

  <imports>

       <include path="META-INF**" />

       <include path="org**" />

  </imports>

But the error is :

org.apache.jasper.JasperException: The absolute uri: http://www.springframework.org/tags/form cannot be resolved in either web.xml or the jar files deployed with this application

org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:51)

org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:409)

org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:116)

org.apache.jasper.compiler.TagLibraryInfoImpl.generateTLDLocation(TagLibraryInfoImpl.java:239)

org.apache.jasper.compiler.TagLibraryInfoImpl.<init>(TagLibraryInfoImpl.java:152)

...

11:24:51,486 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/springmvc].[jboss-as-kitchensink]] (http--127.0.0.1-8080-2) Servlet.service() for servlet jboss-as-kitchensink threw exception: org.apache.jasper.JasperException: The absolute uri: http://www.springframework.org/tags/form cannot be resolved in either web.xml or the jar files deployed with this application

        at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:51) [jbossweb-7.0.13.Final.jar:]

Where am I wrong?

How can I instruct Jboss-Modules to export *.tld files?

The files missing are:

META-INF/spring-form.tld

META-INF/spring.tld

Of course, I can bypass the problem removing spring-webmvc.jar from the module and putting it inside the war, but I would like to try to solve this problem

making my application completed modularized.

Thanks

I found a same problem in:

https://community.jboss.org/thread/196133

And answered :

Right now JBoss conforms to the spec, in that taglib tlds are only automatically found in jars in the WEB-INF/lib directory.

You could extract the various Spring tlds and add them to each webapp in your build process.

Check the spec or a JSP book on where to put them.

Thus the only working solution is to put the tag files inside the war: it works but it is not a good solution.

I found a simple solution:

try to extract all tld files and put them inside the WEB-INF directory automatically using Maven:

   <plugin>

    <groupId>org.apache.maven.plugins</groupId>

    <artifactId>maven-dependency-plugin</artifactId>

    <executions>

     <execution>

      <id>extract-tld</id>

      <phase>generate-resources</phase>

      <goals>

       <goal>unpack</goal>

      </goals>

      <configuration>

       <artifactItems>

        <artifactItem>

         <groupId>org.springframework</groupId>

         <artifactId>spring-webmvc</artifactId>

         <version>${version.spring}</version>

         <outputDirectory>src/main/webapp/WEB-INF</outputDirectory>

         <includes>META-INF/*.tld</includes>

        </artifactItem>

       </artifactItems>

      </configuration>

     </execution>

    </executions>

   </plugin>

It works perfectly!

And the spring-webmvc.jar is loaded using the module definition.

Bye.
