mySoftwareList is an ArrayList. SO if you write ${mySoftwareList.assetNumber}, you're asking the container to call the method getAssetNumber() on an object of type ArrayList. ArrayList doesn't have such a method.

If you want to call this method on every element of the list, then iterate through the list:

<c:forEach var="element" items="${mySoftwareList}>
    ${element.assetNumber}<br/>
</c:forEach>

If you only have one instance, then simply don't store it in a list and pass it directly to the view:

new ModelAndView("swl_mySoftwareList","devTechBean", devTechBean);

${devTechBean.assetNumber}
