トラブル/Java

はじめに

http://blogs.yahoo.co.jp/dk521123/36056462.html
で行った「Axis2 と Eclipse を使って、 新規にWebサービスを構築する」際にトラブルがあったので
解決策を記録しておく

[1] エラー「NoClassDefFoundError: org/apache/ws/commons/schema/resolver/URIResolver」が表示

 * Axis2でWebサービスを構築し、Tomcatを起動すると以下「エラー内容」が表示されてしまう

原因

 * XmlSchema.jar がなかったため

解決策

以下のJARをTomcatは以下のlibに追加する
 * XmlSchema.jar(今回は「xmlschema-core-2.2.1.jar」)

[INFO] org.apache.axis2.deployment.DeploymentException: java.lang.NoClassDefFoundError: javax/ws/rs/Produces

原因

 * jersey.jar がなかったため
 * なお、余談だが、jersey(ジャージ)については、以下の関連記事でも扱った
http://blogs.yahoo.co.jp/dk521123/32824085.html

解決策

以下のJARをTomcatは以下のlibに追加する
 * jersey.jar(今回は「jersey-bundle-1.19.1.jar」)
https://jersey.java.net/download.html
