Support Jakarta EE 10 including major dependency updates (spring boot 3.3, camel 4.4, CXF 4.1)

[Thopap]

As part of this issue, IPF will be updated to the Jakarta EE 10, which also require certain other major dependency updates.

• Migrate from javax -> jakarta (JEE 10)
• Java 17 as minimum
• Spring Framework 6
• Spring Boot 3
• CXF 4.1 (waiting for https://issues.apache.org/jira/browse/CXF-8671)
• Camel 4.4 (planned for may 2023: https://camel.apache.org/blog/2023/01/camel4roadmap/ )
• Tomcat 10
• HerasAF 3.0.2 (Support Jakarta EE 10 tailorfastGmbH/herasaf-xacml-core#13)
• Hapi FHIR 7.x (Migrate javax.servlet to jakarta.servlet and upgrade to Spring 6 and Boot 3 hapifhir/hapi-fhir#2082)

There is a blocker so far as hapi-fhir is still on javax-based JEE version. There is increasingly interest documented in hapifhir/hapi-fhir#2082. There is a survey on https://forms.gle/tMybKV9VrGRaTsrf9, end of 2023 could be a delivery date for Jakarta EE support

Another issue is HL7v3 request/response translation from IHE Gazelle JAXB models (net.ihe.gazelle:hl7v3-code-jar and its transitive dependencies) that are also annotated with the old XmlBind annotations.
Same is true for herasaf-xacml-core

[Thopap]

For heras-xacml-core a new version 3.0.2 with J2EE 10 Jaxb compatiblity is now available.

Hi @Thopap, We are using IPF's latest version i.e., 4.7.0. We wanted to upgrade our projects to spring 6 but due to incompatibility with IPF modules we could not do it. I could see there are couple of mile stones.
Is there any timeline that we have for the release of IPF 5.0 ?

[ohr]

We mainly depend on hapifhir/hapi-fhir#2082 to be fixed, which seems to be targeted towards November 2023. Camel 4.0 should have a release, too, but this can be expected soon.

Some HL7v3 model library is also stuck on javax, but I don't expect this to change anytime soon; so I would rather remove this library.

Are you referring to the gazelle library? If this library is removed, does this also affect ITIs, such as ITI-44,ITI-45 which are based on it? Will they also be removed from ipf?

[unixoid]

@cyrillzadra No worries, this library is not essential for HL7v3 components. Moreover, we need these components by ourselves and would not remove them :-)

For info, HAPI FHIR has completed the migration to Jakarta:

HAPI FHIR 6.11.5-SNAPSHOT and later are using the new Jakarta APIs. This will be released as HAPI FHIR 7.0.0 in Feb 2024.

CXF 4.1 is then the last blocker?

[ohr]

HAPI FHIR has merged back the migration into its develop build, but there are no tags yet we could consume.
I keep the feature/414-jee10 branch updated with all the other stuff, but I have left all FHIR libraries disabled there.

Regarding Gazelle HL7v3 model library (hl7v3-code): this library and its dependencies don't come with any licensing information, so we have to remove it from the IPF distribution. A license is a grant of rights. No license - no rights to use.

For documentation purpose:

CXF 4.0 + IPF 5 is basically working fine with the following limitation / special-case-exception:
In Case a async webservice responder endpoint is used + cxf Message Logging is enabled, CXF will run into a NullPointer in Netty because CXF preserve the HTTP Servlet Request object even if the HTTP request / response is already done.

In IPF one testcase was affected (testIti56 ) which was currently fixed by disable the Message Logging (84c8591)

So basically CXF 4.1 will fix this handling:

Great work, all!

I'm testing our software in combination with this branch. The major upgrade is looking good.

CXF 4.1 https://github.com/apache/cxf/releases/tag/cxf-4.1.0 resolved https://issues.apache.org/jira/browse/CXF-8671 cool! 🥳
