java - JMS strange problem -

-

i have problem in system ~500 servers communicating central server through jms on ~1000 topics. it's 10 year old system , worked until few months ago.

in last 3 months had these types of errors:

  • central server can't deserialize integer because integer in message has wrong serialversionid

    deserialize message failed. - cause: java.io.invalidclassexception: java.lang.integer; local class incompatible: stream classdesc serialversionuid = 1360651450463909473, local class serialversionuid = 1360826667806852920

  • central server can't deserialize unknown class

    deserialize message failed. - cause: java.lang.classnotfoundexception: no classloaders found for: javnteger.integer

  • jms tries instantiate number class abstract

    caught jvm error: java.lang.instantiationerror: java.lang.number

for errors problem localized in 1 random topic. if messages topic deleted , sent again servers went ok.

i'm suspecting jms hardware. hdd ok. need test memory , don't know next.

anyone has suggestion?

it's not jvm issue. @ least far jdk 1.2 (actually 1.0.2 if believe comment in java.lang.integer source distributed jdk), integer's serialversionuid has been "1360826667806852920l", matches "local class" version. they've never changed in order preserve backward compatibility. fact combined "classnotfoundexception: javnteger.integer" (should java.lang.integer) points unmistakably data corruption. either sender, receiver, or network corrupting messages. bad ram seem culprit, if it's intermittent , seldom. if network, happen more , less predictable.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
