[jbosstools-issues] [JBoss JIRA] (JBIDE-21943) Errors validating jboss-ejb3.xml

Errors validating jboss-ejb3.xml -------------------------------- Key: JBIDE-21943 URL: https://issues.jboss.org/browse/JBIDE-21943 Project: Tools (JBoss Tools) Issue Type: Bug Components: upstream Affects Versions: 4.3.0.Final Reporter: Bartosz Spyrko-Śmietanko Assignee: Rob Stryker Priority: Minor Fix For: 4.3.1.CR1 Trying to include urn:trans-timeout element in jboss-ejb3.xml leads to a validation failure: {noformat} cvc-complex-type.2.4.a: Invalid content was found starting with element 'tx:trans-timeout'. One of '{"http://java.sun.com/xml/ns/javaee":container-transaction-entry}' is expected. {noformat} and a warning: {noformat} cvc-complex-type.2.4.a: Invalid content was found starting with element 'tx:trans-timeout'. One of '{"http://java.sun.com/xml/ns/javaee":container-transaction-entry}' is expected. {noformat} Example jboss-ejb3.xml file: {noformat} <?xml version="1.0" encoding="UTF-8"?> <jboss:ejb-jar version="3.1" impl-version="2.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:jboss="http://www.jboss.com/xml/ns/javaee" xmlns:tx="urn:trans-timeout" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.jboss.com/xml/ns/javaee http://www.jboss.org/j2ee/schema/jboss-ejb3-2_0.xsd http://java.sun.com/xml/ns/javaee http://www.jboss.org/j2ee/schema/jboss-ejb3-spec-2_0.xsd urn:trans-timeout http://www.jboss.org/j2ee/schema/trans-timeout-1_0.xsd " > <assembly-descriptor> <container-transaction> <description>foobar</description> <method> <ejb-name>foobar</ejb-name> <method-name>foobar</method-name> </method> <trans-attribute>Supports</trans-attribute> <tx:trans-timeout> <tx:timeout>100</tx:timeout> <tx:unit>Seconds</tx:unit> </tx:trans-timeout> </container-transaction> </assembly-descriptor> </jboss:ejb-jar> {noformat} I think the issue might be related to how Eclipse matches the entries in XML Catalog - giving priority to schemaLocation over namespace match [1]. Since the trans-transactions schema is only referenced via urn:trans-timeout namespace in the catalog, Eclipse tries to download it from jboss.org, fails and never uses the version shipped with Tools.
