This is not a general problem as for example Tomcat 10 happily deploys the example application and also parses the web.xml. I validated that by adding `context-param` elements to `web.xml` and changing `session-timeout` and read these values successfully from a JSP page. Why do you think this is an issue rooted in NetBeans and not in OpenEJB? Let me explain: - we need to examine the XML schema for the file. That is references from the root element and is `https://jakarta.ee/xml/ns/jakartaee/web-app_6_0.xsd`. - that schema does not hold the definition for `session-timeout`, so we follow the import into `https://jakarta.ee/xml/ns/jakartaee/web-common_6_0.xsd` - There `session-timeout` is typed as `jakartaee:xsdIntegerType`, so we need to locate that - That type can be found in the import `https://jakarta.ee/xml/ns/jakartaee/jakartaee_10.xsd` - The type is an extension of `xsd:integer` - For the definition of `xsd:integer` I would checl the XML Schema spec and land here: https://www.w3.org/TR/xmlschema-2/ - There `integer` is defined to be derived from `decimal`, which in turn is a basic type, ok, not too helpful - But the documentation of `decimal` links to `whiteSpace` (Section 4.3.6) and here it becomes interesting. > whiteSpace is applicable to all [·atomic·](https://www.w3.org/TR/xmlschema-2/#dt-atomic) and [·list·](https://www.w3.org/TR/xmlschema-2/#dt-list) datatypes. For all [·atomic·](https://www.w3.org/TR/xmlschema-2/#dt-atomic) datatypes other than [string](https://www.w3.org/TR/xmlschema-2/#string) (and types [·derived·](https://www.w3.org/TR/xmlschema-2/#dt-derived) by [·restriction·](https://www.w3.org/TR/xmlschema-2/#dt-restriction) from it) the value of whiteSpace is collapse and cannot be changed by a schema author; My understanding that `integer` qualifies as atomic. And thus whitespace handling `collapse` applies: > **replace** > All occurrences of #x9 (tab), #xA (line feed) and #xD (carriage return) are replaced with #x20 (space) > **collapse** > After the processing implied by replace, contiguous sequences of #x20's are collapsed to a single #x20, and leading and trailing #x20's are removed. For the concrete case in the default `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> ``` we find the sequence: "newline", "a few spaces", "the numbers 3 and 0", "a few spaces" "newline", "a few spaces" as the content of `session-timeout`. Applying `replace` we reach "a few spaces", "the number 3 and 0", "a few spaces". Applying `collapse` we reach "the numbers 3 and 0". That in turn should parse cleanly as an integer. -- This is an automated message from the Apache Git Service.
