Render an Image
Hi,
i tried several ways to render an image with an myfaces-tag but with no success.
Really frustrating...
How can i render this Hex-String???
Hex-String:FFD8FFE000104A46494600010100000100010000FFDB004300080606070605080707070909080A0C140D0C0B0B0C1912130F141D1A1F1E1D1A1C1C20242E2720222C231C1C2837292C30313434341F27393D38323C2E333432FFDB0043010909090C0B0C180D0D1832211C213232323232323232323232323232323232323232323232323232323232323232323232323232323232323232323232323232FFC00011080066006A03012200021101031101FFC4001B00000202030100000000000000000000000506030700010402FFC4003A100001030302050204030605050000000001020304000511122106133141512261147181911523A1073242B1C1D11625337292445273E1F1FFC4001B01000203010101000000000000000000000203000105040607FFC40029110002020201040201030500000000000001020011030421122231410513517191B1326181C1F0FFDA000C03010002110311003F00BBF462B34835269F7AC29DEA4A322D2335B2302BDE2B4A1EF5254E75AC246F5CCF3FE9246F53C864A9340AE53D9B61692FA88E728A13B77092AFE9FA8A186A09200904B9B97797A8051DC027734354A4B849041DF071E6B924BECCBB846255BB8A2948FA7FEAA6BADBA4DBE1A64C2381AFF312AF56AFBFCBAD0DDCD56F8C2AA075771F466CA6B4123BD430E7A266B484143A8FDE41F1E6A742D2E36169E86A5CCECB89F131471444D288C6C2A322A6C77AF045145484A76F35E748F153115AD3524966815B20019AE69AF2E3DBDF79BD216DB654350C8D8668143E2A796C85C8880A543214D1C7E87FBD5DC763D7C9914B20B99378DAD6CC72B88B5497356909D25001F7246D40A771A4D47E53F1A13AD389FF004D2B215F7CD03F8B448BA4A6647362B4EACAD4D2104EA24EF8237C6F5CB7E54416F31ADF05C2F20613AD18A0622AEE7A3C1F17AEAC15D49B8FB68E21FC4186D214528650A71D2EEEE2C0380079EBD7DBA026A296B62E17882A5A1C69D4092CA01E9CDC247D7D3A8D23DB5892988CA96F24940C38D058D4B237054904109CF7F38DB15E5574B8DC50A3F1ED32B66407A2B8B7348192A4AB71D09DC907A8E80770B3EE646D691C3909C7C8063140B0B264B6F15BA892824A139CFD68D4C8373723968C825B3FF73605295A7F6806DEC08E23EA4B49012A7318E83A104E71D3B5754BFDA4392195A52C202B1E9232403EF427228334FEBDBCCC1FA78FEF03CE8AB66E8CB5CF2DAD4541B7104EF8EC718AEFB44C4A9975A71785B654BCAB00E9D4704FDB140DFBC26E717E1DC6D2D3E824A16938C1ED8F150BB70369B84889CD0B473429CDC12A20023A9FF6E7E46A06F703E4B19C8CB8EBBA39B8EA10E21A2AF5AF3A479C56CEE4508B8B0FC8B5C39915CD4EE703AFEF75F1DF15E3F107E1BC639482509D6E6BCF53D81F6E9F4A3EAE67037C639A18CD9863A1AD64D41125B731AD68D88EA3C54D9A3B99CE8C8C5585112CB5A10E36A42D21485021408C822AB9E2616FE1DB9B0C3525C4A1C6CAD4D294484277031F3DF626840E28E208CDAA6B4B712DA54094BAA2B0B1EC0D735C2EF1AE73D976EACF343E8CBA1274A920F4D3E081DBFBD0B357137F5FE3F36ABF539B5FC08CF61F87B9A549412C2746B494A02750C907AF8C7EA2B2F8888DC6434C32D28B848321C1929C75273BD2B44BEB906D2E301AE6436DC7034E9187084EC7D23AECAEA2B96E7C62C048E52A3A0A87A836BCEE3000391B0D3FCBEE9390D54A0E464FB2FB4425780A836D4C3B4447A4ADC5A4499206025246773DBFA0AE662DAC4AB6261CF774A8ACB6D3CDED839DBE5D850B7AF93DA80A62DA996653993312D37A4249CE00DFD49C139073ED8CEFE33727EDCD3658E5A82794DB415B04000A4EFBEAC9567BF4AB37E63B57672E4CB46E8FBFF70CDB6D522DAEA605C2536438AC34F2919D43B0CF407E74C0BE1980980B752D871C2082A50DC7CBC556B278967429288B3DCD6D8243895AB6C8247A4F5EDF4A6CB0F14485A64C4E496CA521495ABA818CE77FFE6C6A0715551BB3B2C4F0DFAFA83AE36A8E5890A4B8E2567263841034A87CF3B1C8F277EB4AC1B75CBC290FB8D9E78217858D8050C0DFDBC669BAEE1E936C0FEB743CE0284290A4A90AC02474EE493EDF4A0379B6AE64054C7141B623B6A79A2D1042403E3B93B7CF0286ED666E7DB36AD76C3F69616965888D679A1B08294A501435103A8F3DE82DD2F909B8CCB4EB6B53E145B775104A0F639EE0E7CD2831C560CC8F15B79EE621010E3870A39246C803A1CF5EF44EF30DD8D1E7F3125C52C21E46A1D73B1FB6D54B7EE68682FD9DC4C231AEAB8D2F5F213CB53606869272A3D8E7A79A636DF4ADB4ACE125401C1232292956E751711094B5A5943292A0125795637E9F5AE25DBE66B56195119D8E834E5EAA9D1B1F109B043DD1A960BF6ABA5DADED28940612AC6948D2563CEF41AE76888C3A57314E87BB15AC003ED4D77CE2111E386EDAB654B3B1D63013F2CE01A54BA58E3DEED1326FC53AECD2D6A0864EA208E9E9EF9A17367C45E3CB902F538A58BDFE1A1C5680B8AFA90C32E969D7F195149C9C01D3B7EB441CE0D6AD780DC343AD1FE2527513F3CF7A09FB38BE474F13336F70A12DAD2E32877F894A51053ABB744E07CEADF75F10DEE52C0C647DB342454E6C39D5DD9C2837FC4AE2D56DBA4994EC78062B0C8253839C800EDE9FD6883F0FF01B9B082F29E050A75DC8D93818D80F7ED4D2E4045D9F57C132528CE92F23657F4C57A7787A3C16D521D0AE6018E6BCE6B5A8F603B0A3A153BDF752FA4F02BC4AEB87B845EE21E279326F081F0CB25D119432A482720157F0F4E82A1E2C8B6E6FF680D263A96151DB02436DA494A800545381D4E9C78EB9A6E55D1AE19616E25465CE782821A6F7D6E1DC247B0006F55719B74B7DF3E29C71ED4EBC5C794E6A090E28602F18ED9F1B8DB7A83998DB8A12C278FCC7C525E9DC3864E5687186D41B584941D58C6BED9CE07D303B50B6E24FB9DADC5C779C941AD215AD6773E319C1C0C7DA8EC579A7AD4875B53C44E569521D0525202402529C74E9B93DCF9DA7E05893E3D9DF61B6995ACBEAD654ACE0EC318FA50A79AA9DBA8B88E3190A8247E62632A810662CAE325995904BC5AF56A07AEE3AE7BD33AA7377EB7729450890941E52D3D1C1DC63B7F7A277EE119F2D0243A865206492D20E7E477DEABBBF596EB0E3B6988E1E6A5649D04A15823B66ACA91EE76E46C431FD983C8E684B17876E7165CA7E4ADB70B8A6DB4A90119214010451FF00888C7FE99DFF0085549C3122F165962535394F13853F124A756B1FEEC9C1F7FBD195F135CDC714B10D785124618591BFD2AC3902711CBF6B13447F99E60710393E6F29119D756A0400A4E76FBED4CFC3D02642E218EE3E421B7F5214D206C3D24E7EE29B6C7C311E2A43CA6407C8F52B6C9F9E2BBAE111B6A430E818E52B24FD08FEB53A4D7718DD8F93C7918E2C6BC115288E33E01916CBEC8B8D894

I don't know how to do that and i haven't find any solution to do that with a myfaces-tag.
In the myfaces-examples a servlet will do that, but how can i render that with a myfaces-tag???
Thanx for your help!

Another component can support this feature. I did not mean <h:graphicImage>
should support this.
But a byte[] in a session bean should be viewed easily on a page. I think I
am not the only one who has a requirement like this.
Cause a component,s:graphicImageDynamic, has already implemented.
A phaselistener like jsf Chart's one and an appropiate component can resolve
this issue I think.
Thx Matthias & Mike..

There's a sandbox component that does this.
s:graphicImageDynamic
However, I don't know if all of the bugs are worked out of it yet --
it tries to do it without a servlet which makes it very difficult.

That doesn't make any sense. h:graphicImage renders a tag not an image.
<img src="..." />
Images are not actually in HTML pages, just tags that insert images.
Then the browser uses an HTTP request to get the images from the
server to insert into the page when the page is rendered. If there was
a byte[] array in the JSF graphicImage component, what would JSF do
with it? It cannot render those bytes in the response as a browser
would not know what to do with them.
If you want a dynamic image, best thing to do is create a servlet then
have the tag just point to that servlet with path & query strings
configured as you need them.
