Otherwise, You may also choose to use, distribute or otherwise make the Covered Software available under the terms of any subsequent version of the License published by the license steward. + o + + 4.3. Modified Versions. + + When You are an Initial Developer and You want to create a new license for Your Original Software, You may create and use a modified version of this License if You: (a) rename the license and remove any references to the name of the license steward (except to note that the license differs from this License); and (b) otherwise make it clear that the license contains terms which differ from this License. + * + + 5.

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU. + * + + 8. U.S. GOVERNMENT END USERS. + + The Covered Software is a âcommercial item,â as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of âcommercial computer softwareâ (as that term is defined at 48 C.F.R. § 252.227-7014(a)(1)) and âcommercial computer software documentationâ as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government End Users acquire Covered Software with only those rights set forth herein. This U.S. Government Rights clause is in lieu of, and supersedes, any other FAR, DFAR, or other clause or provision that addresses Government rights in computer software under this License. + * + + 9. MISCELLANEOUS. + + This License represents the complete agreement concerning subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable.

Any litigation relating to this License shall be subject to the jurisdiction of the courts located in the jurisdiction and venue specified in a notice contained within the Original Software, with the losing party responsible for costs, including, without limitation, court costs and reasonable attorneysâ fees and expenses. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded. Any law or regulation which provides that the language of a contr act shall be construed against the drafter shall not apply to this License. You agree that You alone are responsible for compliance with the United States export administration regulations (and the export control laws and regulation of any other countries) when You use, distribute or otherwise make available any Covered Software. + * + + 10. RESPONSIBILITY FOR CLAIMS. + + As between Initial Developer and the Contributors, each party is responsible for claims and damages arising, directly or indirectly, out of its utilization of rights under this License and You agree to work with Initial Developer and Contributors to distribute such responsibility on an equitable basis. Nothing herein is intended or shall be deemed to constitute any admission of liability. http://git-wip-us.apache.org/repos/asf/cxf/blob/23d6d663/distribution/src/main/release/samples/jax_rs/sse/README.md ---------------------------------------------------------------------- diff --git a/distribution/src/main/release/samples/jax_rs/sse/README.md b/distribution/src/main/release/samples/jax_rs/sse/README.md new file mode 100644 index 0000000..3f98f8c --- /dev/null +++ b/distribution/src/main/release/samples/jax_rs/sse/README.md @@ -0,0 +1,4 @@ +How to use +============== + +http://localhost:8686/static/ http://git-wip-us.apache.org/repos/asf/cxf/blob/23d6d663/distribution/src/main/release/samples/jax_rs/sse/pom.xml ---------------------------------------------------------------------- diff --git a/distribution/src/main/release/samples/jax_rs/sse/pom.xml b/distribution/src/main/release/samples/jax_rs/sse/pom.xml new file mode 100644 index 0000000..7dde933 --- /dev/null +++ b/distribution/src/main/release/samples/jax_rs/sse/pom.xml @@ -0,0 +1,152 @@ +<project xmlns="http://maven.apache.org/POM/4.0.0";
