Hi. I'm toatally newbie here and having a problem. I tried to POST a xml file which is made dynamically on other server. I want to upload it into PE server and convert it into PDF. Parameters I used with is file-type=xml, type=pdf, f=convert. I always has the result saying code:500 internal server error. Is there a good example to do this? What I want to do is, - Upload a XML file by HTTP/POST - Use xsl that was uploaded in PE server before - Get PDF as responce as application/pdf - Do this in Java I'd be really glad if I could get sample source or pointers(links). Would someone please help me?
