Kettle3.2的Webstart

在尝试Kettle的webstart方式运行时，遇到了一点问题，最终解决。

 

一、下载kettle

从http://sourceforge.net/projects/pentaho/files/下载pdi3.2(也就是kettle)。

 

二、ant webstart

解压后等到kettle trunk目录，在cmd下，直接ant webstart

如果出现编译错误，是因为没有把当前路径加到classpath。

 

再尝试，会出现以下错误：

signjar] Signing JAR: G:\Work\Kettle\webstart\libext\salesforce\saaj.jar
  [signjar] 警告： 签名者证书将在六个月内过期。
  [signjar] Signing JAR: G:\Work\Kettle\webstart\libext\salesforce\salesforce-1.0.jar
  [signjar] jarsigner： 无法对 jar 进行签名 ： java.util.zip.ZipException: duplicate entry: com/sforce/soap/partner/AssignmentRuleHeader.class BUILD FAILED

 

产生的原因为libext\salesforce\salesforce-1.0.jar 里面有重复的文件，不知道为什么会这样，删除重复的文件后（可先用WinRAR解缩，再用压缩），就正常了。

 

三、部署

将生成的war包，改名为了kettle.war，放到Tomcat的webapps下。

访问http://localhost:8080/kettle，就可以页面上看到一个链接，点击链接将开始下载jnlp依赖的jar文件。

如果你使用的Tomcat是6.0之前的，请在%tomcat_home%/conf/web.xml文件中，添加

 <mime-mapping>
        <extension>jnlp</extension>
        <mime-type>application/x-java-jnlp-file</mime-type>
    </mime-mapping>

 

下载过程中，会出现一个“jar签名不一致 ”的错误，产生的原因是spoon.jnlp依赖到的部分jar，已经有其他厂商签名过了。

请删除spoon.jnlp中这段代码：

<jar href="libswt/common.jar"/>
  <jar href="libswt/commands.jar"/>
  <jar href="libswt/jface.jar"/>
  <jar href="libswt/runtime.jar"/>

 

继续尝试，还会提示找不到Spoon类 ，需要修改spoon.jnlp，指定Main文件所在的jar

 <jar href="lib/kettle-ui-swt.jar" main="true"/>

 

继续尝试，已经可以完全下载，出现安全提示，点击“运行”之后，屏幕闪了一下，就没有任何显示了。

 

启用Java 控制台，发现错误如下：

Exception in thread "javawsApplicationMain" java.lang.NoClassDefFoundError: org/pentaho/di/core/database/DatabaseMeta
	at java.lang.Class.getDeclaredMethods0(Native Method)
	at java.lang.Class.privateGetDeclaredMethods(Unknown Source)
	at java.lang.Class.getMethod0(Unknown Source)

 

因为没有导入kettle-db.jar，修改spoon.jnpl

 <jar href="lib/kettle-core.jar"/>
  <jar href="lib/kettle-ui-swt.jar" main="true"/>
  <jar href="lib/kettle-engine.jar"/>
   <jar href="lib/kettle-db.jar"/>

 

还是会有异常出现说找不到图片文件。

将源文件的ui目录复制到桌面，再运行，窗口已经可以显示，但还是有错误信息：
