php - Set the zoom level for the html file generated using PHPExcel? -

i trying generate html file using phpexcel. have more 30 columns , zoom page. i've tried using code below, hasn't worked. $objphpexcel->getactivesheet()->getpagesetup()->setfittopage(true); $objphpexcel->getactivesheet()->getpagesetup()->setfittowidth(2); i've tried using this, hasn't worked either. $objphpexcel->getactivesheet()->getsheetview()->setzoomscale(250); both options don't work in case of html page, zoom works if excel file. going wrong? as may see chaining of commands, setzoomscale() method part of worksheet class , have impact in case worksheet written, not when read. the phpdoc phpexcel lists internal command _writesheetviews() excel2007 writer , _storezoom old excel versions whereas phpexcel_writer_html doesn't offer similar behavior. what may try adding custom css styling created html file may use smaller font-sizes table. afaik won't able change zoom level of browser programmatically

Cassandra control SSTable size -

is there way control max size of sstable, example 100 mb when there more 100mb of data cf, cassandra creates next sstable? unfortunately answer not simple, sizes of sstables influenced compaction strategy , there no direct way control max sstable size. sstables created when memtables flushed disk sstables. size of these tables depends on memtable settings , size of heap ( memtable_total_space_in_mb being large influencer). typically these sstables pretty small. sstables merged part of process called compaction . if use size-tiered compaction strategy have opportunity have large sstables. stcs combine sstables in minor compaction when there @ least min_threshold (default 4) sstables of same size combining them 1 file, expiring data , merging keys. has possibility create large sstables after while. using leveled compaction strategy there sstable_size_in_mb option controls target size sstables. in general sstables less or equal size unless have partition key lo

web services - Random questions on JAX-WS and JAX-RPC compatibilities -

we have web service running on old version of application server. old application server running on java ee 1.4. clients on server running on same version of application server. the move upgrade our application server has started. new version run on java ee 6. thing is, clients still run on old version. still able access web service running on java ee 6? if yes answer #2, have follow question below our web service created using jax-ws. mean should generate client classes jax-rpc? clients running in old version able access it? if yes, how? to rephrase question, if have jax-ws web service, how generate jax-ws client , how generate jax-rpc client? ive done initial research , seem done same way, i'm not sure correct. im confused. thanks since mentioned j2ee 1.4, guessing web service based upon jax-rpc 1.x standard. java ee 6 based web service based on jax-ws, suggest generating client stubs using wsimport command using wsdl new service generate stub classes.
