one of servers running out of capacity, due weblogic's stage folder. i've been looking information , seems temporal folder, unlike older versions, on wl11g folder out of tmp folder. i'm not sure whether or not can safely remove it. stage directory weblogic copies applications needs deploy on managed servers. wls not delete file folder. in long run if have done deployment of many versions of application folder can become rather large. so yes can delete contents of folder. @ time of restart wls copy necessary files folder (this take time).

the following cryptojs code run in normal speed in ie9 very slow in ie7, reason behind , method speed script in ie7? var keylength = 256; var iteration = 1000; var salt = cryptojs.lib.wordarray.random(128/8); var key = cryptojs.pbkdf2(passphrase, salt, { keysize: keylength/32, iterations: iteration }); var iv = cryptojs.lib.wordarray.random(128/8); var loginpassword = document.getelementsbyname("password")[0].value; var encrypted = cryptojs.aes.encrypt(loginpassword, key, {iv:iv},{mode:cryptojs.mode.cbc,padding: cryptojs.pad.pkcs7}); microsoft has improved speed of javascript engine in ie9 bring par other modern js engines (see here ). i'm afraid there's nothing can done improve performance of ie7 engine. of course, in specific case, reduce number of iterations, although not familiar enough pbkdf2 how far can reduce before function becomes unsafe. option consider moving password hashing server...

assume have 3 bundles a , b , b1 . bundle a starting point of application. bundle b provides api of service used a . bundle b1 implementation of service. basically, bundle a has set of records processes 1 after other. there no order processing records. i improve performance of application processing subsets of records concurrently. i thought 2 different ways: multiple instances of bundle and, bundle multiple threads. afaik, not possible add multiple instances of same bundle (i.e. same osgi identity) in osgi container. regarding second possibility, each thread created bundle a have own identity. , service exported b1 needs know identity of thread uses it. thus, thought servicefactoy fit here. however, i've read once service instance obtained bundle, cached. therefore, threads same service instance. am right? if yes, "right way" implement model? feel free propose me different approach more osgi friendly. thanks, mickael edit: another possibil...
