Question

我需要从pentaho ETL运行一个jar文件。我已将我的Testvmarguments.jar文件放在

中

服务器/数据集成服务器/ Tomcat的/ lib中

。创建作业，使用shell脚本步骤执行jar文件

以下是我的日志： -

有人可以帮助克服上述错误。

DI环境中的
jar文件.. !!!

请在link

找到附件

我使用shell脚本的原因是执行带有运行时参数的jar。

java -Dfilepath = / home / Myfolder / Myname / Test -Dname = Myname -jar Testvmarguments.jar

这是我的一段代码

 package com.alliance.test;

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;

public class TestCommandLine
{
  public static void main(String[] args)
    throws Exception
  {
    String filename = null;
    String employeeName = null;
    if (System.getProperty("filepath") != null) {
      filename = System.getProperty("filepath");
    }
    if (System.getProperty("name") != null) {
      employeeName = System.getProperty("name");
    }
    File file = new File(filename + "Test.txt");
    if (!file.exists())
      file.createNewFile();
    FileWriter fw = new FileWriter(file);
    BufferedWriter out = new BufferedWriter(fw);
    out.write(filename + "\n");
    out.write(employeeName);
    out.close();
    fw.close();
  }
}

谢谢，苏里亚

Answer 1

不要将其称为外部进程，因为您不必启动新的vm。而只是将jar添加到lib文件夹并从javascript步骤或udjc中调用它

Answer 2

将jar放入数据集成的目录文件夹（server / data-integration-server / tomcat）后尝试

Answer 3

我将jar复制到libext文件夹。在JS步骤中使用以下语句

var testval2 = org.wtc.pentaho.PentahoSample.testSample（“surya”）;
