Improve feedback after invalid request for creating a datasource ---------------------------------------------------------------- Key: WFLY-8462 URL: https://issues.jboss.org/browse/WFLY-8462 Project: WildFly Issue Type: Enhancement Components: JCA, Web Console Affects Versions: 10.1.0.Final Reporter: Karl-Philipp Richter Assignee: Harald Pehl Priority: Major After creating a Non-XA datasource in the web frontend and pressing finish on the last dialog page, I get the message "Unknown error" and the data entered into the form is lost. Clicking on "Unknown error" a dialog is displayed with the content ``` Unexpected HTTP response: 500 Request { "name" => "jdbc/linuxtracker2", "jta" => true, "enabled" => true, "user-name" => "APP", "password" => "APP", "jndi-name" => "java:/jdbc/linuxtracker2", "use-ccm" => true, "pool-name" => "jdbc/linuxtracker2_Pool", "connection-url" => "jdbc:derby://localhost:1527/derby-pool", "driver-class" => "org.apache.derby.jdbc.ClientDriver", "driver-name" => "jdbc/linuxtracker2", "operation" => "add", "address" => [ ("subsystem" => "datasources"), ("data-source" => "jdbc/linuxtracker2") ] } Response Internal Server Error { "outcome" => "failed", "failure-description" => { "WFLYCTL0412: Required services that are not installed:" => ["jboss.jdbc-driver.jdbc/linuxtracker2"], "WFLYCTL0180: Services with missing/unavailable dependencies" => [ "org.wildfly.data-source.jdbc/linuxtracker2 is missing [jboss.jdbc-driver.jdbc/linuxtracker2]", "jboss.driver-demander.java:/jdbc/linuxtracker2 is missing [jboss.jdbc-driver.jdbc/linuxtracker2]" ] }, "rolled-back" => true } ``` which is extremely unhelpful given the fact that an error message listing and explaining the cause for the failure could be displayed (e.g. "the datasource xy couldn't be created because the name doesn't match the requirement yz"). It's hard to guess that clicking on the "Unknown error" popup opens a dialog.
