错误：包含版本的项目 <unknown> 部署描述符需要XMI格式绑定或扩展文件。 IBM的web-bnd.xml

Question

I have upgraded editor from Rad 7.5 to 8 and maven 2 to 3 . This happens just after importing existing maven projects in RAD 8, but I have no errors on any pom files.

The issue is with two xml files :

Projects containing version deployment descriptors require XMI-format bindings or extensions files. ibm-web-bnd.xml /DocViewerWeb/WebContent/WEB-INF Unknown Validation Message

Projects containing version deployment descriptors require XMI-format bindings or extensions files. ibm-web-ext.xml /DocViewerWeb/WebContent/WEB-INF Unknown Validation Message

Contents of those two files are:

<?xml version="1.0" encoding="UTF-8"?>
<web-bnd 
    xmlns="http://websphere.ibm.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://websphere.ibm.com/xml/ns/javaee http://websphere.ibm.com/xml/ns/javaee/ibm-web-bnd_1_0.xsd"
    version="1.0">

    <virtual-host name="default_host" />

  <ejb-ref name="ejb/MaintenanceServices" binding-name="ejblocal:com.tscdv.document.b.MaintenanceServices" />
  <ejb-ref name="ejb/ServiceTipsDocumentServices" binding-name="ejblocal:com.tscdv.document.b.ServiceTipsDocumentServices" />
  <ejb-ref name="ejb/ActivityDocumentServices" binding-name="ejblocal:com.tscdv.document.b.ActivityDocumentServices" />
  <ejb-ref name="ejb/BulletinDocumentServices" binding-name="ejblocal:com.tscdv.document.b.BulletinDocumentServices" />
  <ejb-ref name="ejb/CommonService" binding-name="ejblocal:com.tscdv.document.b.CommonService" />
  <ejb-ref name="ejb/AdminServices" binding-name="ejblocal:com.tscdv.document.b.AdminServices" />

</web-bnd>

and

<?xml version="1.0" encoding="UTF-8"?>
<web-ext
    xmlns="http://websphere.ibm.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://websphere.ibm.com/xml/ns/javaee http://websphere.ibm.com/xml/ns/javaee/ibm-web-ext_1_0.xsd"
    version="1.0">

    <reload-interval value="3"/>
    <context-root uri="DocViewerWeb" />
    <enable-directory-browsing value="true"/>
    <enable-file-serving value="true"/>
    <enable-reloading value="true"/>
    <enable-serving-servlets-by-class-name value="true" />

</web-ext>

What could be the problem here?

I have posted another possibly related issue : JSR250: CommonAnnotations for Java, 2.3: @Resource methods must be setters that follow the standard JavaBeans convention

Answer 1

Projects containing web.xml with version="2.4" or lower require ibm-web-bnd. xmi and ibm-web-ext. xmi .

Projects containing web.xml with version="2.5" or higher require ibm-web-bnd. xml and ibm-web-ext. xml .

Perhaps the change in tool versions has upgraded your web.xml version to 2.5, and now RAD is warning that this is incompatible with your web.xml?

Answer 2

In extension to the comment on bkail's answer (which is helpful) if you want to use web.xml version 2.5 you should use the following prolog and parent node. Technically the comment is inaccurate as the namespaces are missing http:// and will cause additional errors if you do not use this:

<?xml version="1.0" encoding="UTF-8"?>
<web-app
  xmlns="http://java.sun.com/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
  version="2.5">
