openoffice doc转PDF

[wangjiangbo2]

我用openoffice把doc文件转PDF，发生错误

java.lang.NoClassDefFoundError: com/sun/star/comp/helper/Bootstrap
at com.artofsolving.jodconverter.openoffice.connection.AbstractOpenOfficeConnection.connect(AbstractOpenOfficeConnection.java:61)



我下载源文件发现61行是 XComponentContext localContext = Bootstrap.createInitialComponentContext(null);



Bootstrap所在的jar包我已引进到项目里

错误信息是找不到 com.sun.star.comp.helper.Bootstrap

你说“Bootstrap所在的jar包我已引进到项目里”

但JVM是不会骗人的，所以还是只能自己检查检查实际的运行环境了。

public void docToPdf() {            
		Date start = new Date();                       
		OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);      
		
		try {    
			 XComponentContext localContext = Bootstrap.createInitialComponentContext(null);
			connection.connect();                
			DocumentConverter converter = new OpenOfficeDocumentConverter(connection);                
			converter.convert(inputFile, outputFile);            
		} catch (Exception cex) {                
			cex.printStackTrace();            
		} finally {                
			// close the connection                
			connection.disconnect();
		}
	}

我随便在一个java里加入 XComponentContext localContext = Bootstrap.createInitialComponentContext(null);
是不报错的

就这些 jar包 ，之前写的 ，可以的，必须启动openOffice，

cd C:\Program Files\OpenOffice.org 3\program
>soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

[MiceRice]

那么另一个问题是：
com.artofsolving.jodconverter.openoffice.connection.AbstractOpenOfficeConnection 这个类所在的JAR包，跟Bootstrap的JAR包，是在同一个装载层级的么？

或者说，你是怎么引入AbstractOpenOfficeConnection的JAR包的？如果是直接配置到CLASSPATH的话，那么Bootstrap的JAR包也需要配置到CLASSPATH中去。

[wangjiangbo2]

编译的时候不报错，但程序执行到XComponentContext localContext = Bootstrap.createInitialComponentContext(null);
还是报java.lang.NoClassDefFoundError: com/sun/star/comp/helper/Bootstrap


AbstractOpenOfficeConnection.class为jodconverter-2.2.2.jar包里的类，



OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);
8100端口我也用如下方法启动：
cd C:\Program Files\OpenOffice.org 3\program

soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

jar包我都有，版本都比你这个新，我下个老版本试试

[wangjiangbo2]

解决了，我换上cai5 的版本jar包就不存在这个问题

[liuguichuan666]

cai5 楼主是什么啊？
