## Axis 1.0 RC1 Release Notes

This is the RC1 release of the Axis SOAP library.

### Rationale for Releasing Axis 1.0

Many users have requested a v1.0 so that they can work from a relatively stable base. Some users have even remained on Apache SOAP until v1.0 of Axis is available. Now Axis has surpassed Apache SOAP in function, performance, and interoperability and, in particular, has passed Sun's JAX-RPC and SAAJ compliance tests, we decided to ship v1.0 as it currently stands.

However, this is far from the end of the road for Axis: there is more documentation to be written; the SOAP v1.2 spec. needs to be tracked to completion and implemented fully; major functional enhancements and architectural improvements are being considered. We particularly encourage you to submit improvements to the documentation, however large or small and in any format, to axis-dev@xml.apache.org. Also, interoperability is always a concern, so please report all replicatable bugs.

### JAX-RPC

This release is intended to be 100% compliant with the JAX-RPC and SAAJ specifications from Sun. The Axis code has successfully passed the all of the JAX-RPC and SAAJ TCK (Technology Compatibility Kit) tests.

### Why AXIS over SOAP 2.2?

The Axis code has:

- Significantly higher performance than Apache SOAP 2.2
- Good interoperability with other SOAP implementations
- A streaming-oriented model for message parsing (SAX, not DOM)
- A modular, configurable message handling architecture
- A pluggable transport framework
- Support for WSDL generation and code generation from WSDL
- An extensive package and functional test suite

### What's New?

Changes since beta-3

- Axis now passes the JAX-RPC and SAAJ TCK test suites.
- Many bugs have been fixed.
- Axis now supports (almost) all XML Schema types in WSDL
- Some basic performance tuning has been done
- Attachments are now supported in WSDL2Java

Changes since beta-2:

- Support for the new version of the DIME spec

Changes since alpha-3:

- Closer to JAX-RPC compliance.
- Support for SOAP Messages with Attachments.
