Eclipse shows the following errors in my Spring applicationContext.xml:
cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'dwr:configuration'. myappservlet-servlet.xml MyApp/src/main/webapp/WEB-INF line 23 XML Problem cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'dwr:controller'. myappservlet-servlet.xml MyApp/src/main/webapp/WEB-INF line 21 XML Problem cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'dwr:remote'. myappservlet-servlet.xml MyApp/src/main/webapp/WEB-INF line 41 XML Problem
When I hover over a position error, it also says:
- schema_reference.4: Failed to read schema document 'http://www.directwebremoting.org/ schema/spring-dwr-3.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.
I confirmed that the root element is actually <xsd: schema>. When I use autocomplete, typing <dwr: Eclipse correctly shows me various options, such as <dwr: configuration>, <dwr: controller>, etc. How can Eclipse know this without reading the diagram?
I use many different namespaces without problems; DWR is the only one that is not allowed. Here is the announcement:
<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.directwebremoting.org/schema/spring-dwr http://www.directwebremoting.org/schema/spring-dwr-3.0.xsd" default-autowire="byName">
I have the latest DWR 3.0.0.116.rc1 in my classpath. If I rip the can of DWR, I find META-INF / spring.handlers containing:
http\://www.directwebremoting.org/schema/spring-dwr=org.directwebremoting.spring.DwrAnnotationNamespaceHandler
and META-INF / spring circuits containing:
http\://www.directwebremoting.org/schema/spring-dwr-2.0.xsd=org/directwebremoting/spring/spring-dwr-2.0.xsd http\://www.directwebremoting.org/schema/spring-dwr-3.0.xsd=org/directwebremoting/spring/spring-dwr-3.0.xsd
Colon acceleration threw me a little, but I assume that everything is correct, otherwise all DWRs will be broken.
Before I grabbed this particular circuit in real time from the DWR site, but I realized this when my production system crashed because the DWR site was omitted.
