pipi.jaf.StringDatasource.java
==============================

package pipi.jaf;

public class StringDataSource implements javax.activation.DataSource{
private java.lang.String data;
private java.lang.String type;

public StringDataSource(java.lang.String data,java.lang.String type){
this.data = data;

}

public java.io.InputStream getInputStream() throws java.io.IOException{
return new java.io.StringBufferInputStream(data);
}

throw new java.io.IOException("it does not support this method now!");
}

public java.lang.String getContentType(){
return type;
}

public java.lang.String getName(){
return "pipi";

//获得邮件会话对象

//创建MIME邮件对象
