Checked this and I see an issue in OpenEJB here. The web application holds this `web.xml`: ```xml <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="https://jakarta.ee/xml/ns/jakartaee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="https://jakarta.ee/xml/ns/jakartaee https://jakarta.ee/xml/ns/jakartaee/web-app_6_0.xsd"; version="6.0"> <session-config> <session-timeout> 30 </session-timeout> </session-config> </web-app> ``` This version is accepted by Apache Tomcat, but not by TomEE. This generates an error output like this: <details> <summary> Relevant part (expand for full trace): ``` Caused by: java.lang.NumberFormatException: For input string: " 30 " at

Reloading Context with name [/mavenproject2] is completed ``` </details> Reformatting the `session-timeout` element to: ```xml <session-timeout>30</session-timeout> ``` makes it work on TomEE too. The question is now: Is the problem in the `web.xml` or in the TomEE parser. Lets have a look at the definition of `session-timeout`. - https://jakarta.ee/xml/ns/jakartaee/web-app_6_0.xsd is referenced from `web.xml`, but does not directly hold the definition. - The definition is in https://jakarta.ee/xml/ns/jakartaee/web-common_6_0.xsd (referenced via the `web-commonType` group): ```xml <xsd:element name="session-timeout" type="jakartaee:xsdIntegerType" minOccurs="0"> <xsd:annotation> <xsd:documentation> The session-timeout element defines the default session timeout interval for all sessions created in this web application. The specified timeout must be expressed in a whole number of minutes. If the timeout is 0 or less, the container ensures the default behaviour of sessions is never to time out. If this element is not specified, the container must set its default timeout period. </xsd:documentation> </xsd:annotation> </xsd:element> ``` - So `session-timeout` is of type `jakartaee:xsdIntegerType`. That is defined in https://jakarta.ee/xml/ns/jakartaee/jakartaee_10.xsd (imported): ```xml <xsd:complexType name="xsdIntegerType"> <xsd:annotation> <xsd:documentation> This type adds an "id" attribute to xsd:integer. </xsd:documentation> </xsd:annotation> <xsd:simpleContent> <xsd:extension base="xsd:integer"> <xsd:attribute name="id" type="xsd:ID"/> </xsd:extension> </xsd:simpleContent> </xsd:complexType> ``` - The definition of `xsd:integer` can be found here: https://www.w3.org/TR/xmlschema11-2/#integer. The important part here is the fixed value of `collapse` for the whitespace facet - https://www.w3.org/TR/xmlschema11-2/#rf-whiteSpace indicates, that the treatment of the values should be: - apply `replace` behavior: All occurrences of #x9 (tab), #xA (line feed) and #xD (carriage return) are replaced with #x20 (space) - After the processing implied by replace, contiguous sequences of #x20's are collapsed to a single #x20, and any #x20 at the start or end of the string is then removed. Based on this, the parser should yield us: `30` for an input of: ``` 30 ``` And this is where I see the problem. The whitespace is not collapsed before the value is fed to `Integer#valueOf`. -- This is an automated message from the Apache Git Service.
