i trying create pdf using tcpdf library. have problem table written method writehtml() though. when table has many rows, rest of moved next page. proper behavior, need to have top margin on new page. tcpdf making default margin, small in case. ive tried use setmargins(), setxy() nothing seems work. looks general margins of pdf has no influcence on content created writehtml(). had similar problem? tcpdf::setmargins($left,$top,$right = -1,$keepmargins = false) and describes parameters as: parameters: $left (float) left margin. $top (float) top margin. $right (float) right margin. default value left one. $keepmargins (boolean) if true overwrites default page margins so, right margin -1 used indicate no right margin supplied , use same left margin. using -50 not valid margin. try instead: $pdf->setmargins(10, 10, 10, true);

what best way of implementing roundtrip receiving xml files , persisting data database using java. have: 1. xml schema & xml data files send me - xsd complex , belongs external party, can not change it 2. created java classes - jaxb generates on 150 classes, unfortunately schema can change - have used maven pom automate process 3. unmarshall xml data files java objects (with jaxb annotation) - data displayed user manipulated 4. persist java objects rdbms (oracle / mysql) - seems jdo suitable solution 5. exporting data - data can exported again xml or excel (for example) i can not find suitable way add jdo metadata or annotations java source code (generated during jaxb process) ensure can persist java classes. working following technologies: - java, maven, jaxb, jdo & jdbc i think datanucleus suited might have change datastores (rdbms / xml / excel) between environments different export destinations. other 2 technologies might need consider is: - spring , ...
