Wildfly not loading the right library

[armahdi]

Hello All,

I am running into a situation where I have added the library but it is not being picked up

at java.lang.Thread.run(Thread.java:722)

My jboss-deployment structure:

<?xml version="1.0" encoding="UTF-8"?>

<jboss-deployment-structure>

    <deployment>

        <dependencies>

            <!--

            we want to use the saaj module provided by JBoss

            it looks like we can't use the implementation provided by the JDK - JBoss somehow does not seem to allow it

            -->

            <module name="com.sun.xml.messaging.saaj" />

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

            <module name="com.gbst.directregistry.configuration" />

            <module name="com.gbst.directregistry.hypersonic" />

            <module name="org.apache.commons-fileupload"/>

        </dependencies>

    </deployment>

</jboss-deployment-structure>

javax.servlet.api in the service/layers/... is where it is located and I have seen that the class is located there.

org.apache.commons-fileupload is something I made myself to contain a class to solve an issue when i had this:

<bean id="multipartResolver"

     class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>

seems like this CommonsMultipartResolver uses : org.apache.commons.fileupload.FileUpload which is not found in the system/layer/.. libs so i added my own lib in module\org\apache\commons-fileupload . Every time i try to invoke my url it throws the error above. Why is WF trying to find ServletInputStream in org.apache.commons-fileupload even though it is already there in the WF System/layers/ libs even though it is located in javax.servlet.api

The error which you are getting is as following:

ClassNotFoundException: javax.servlet.ServletInputStream from [Module "org.apache.commons-fileupload:main" 

Above indicates that your custom module "org.apache.commons-fileupload" module's   module.xml you should add a dependency to the <module name="javax.servlet.api"/>

So try editing your   $JBOSS_HOME/modules/system/layers/base/org/apache/commons-fileupload/main/module.xml and  add the dependency <module name="javax.servlet.api"/>  then restart Wildfly and retest.

Thanks Jay,

That worked. Awesome.
