RE: Loadbalancer.jar HOWTO?
OK, I have find out how to do this You have to edit a loadbalance.xml, like -= load-balancer host="[ALL]" port="80" selection-type="random" use-ip="false" use-session-id="true" island backend-server host="localhost" port="8080"/ /island island backend-server host="localhost" port="8081"/ /island /load-balancer then run clusters and loadbalancer( by java -jar loadbalancer.jar) but I found the follwing bugs and weakness 1. -config parameter not work, loadbalancer will always use config/loadbalance.xml and not the default config file config/load-balance.xml it says. 2 use-ip can't be "true" , I don't know why , just can't 3. if island is down, then loadbalancer will remove it , but loadbalancer will never know it has recover, and the island will remove forever the report was tested on Orion 1.3.1 with Win2k -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Karl Avedal Sent: Wednesday, September 06, 2000 3:29 PM To: Orion-Interest Subject: Re: Loadbalancer.jar HOWTO?

Declare variable using Taglib TEI
While I am tring to declare variable in TEI
I return the VariableInfo array in TEI class like this
==
return new VariableInfo[]
{
new VariableInfo[]{
data.getAttributeString("errorId"),
, "java.lang.String[]"
, true
, VariableInfo.AT_END
}
{
Orion just told me that
No such bean type "java.lang.String[]"
It's terrible that I can't delcare array type. Now I use Collection instead, but this
is not a good way.
Is this a bug?

RE: Declare variable using Taglib TEI
So, there is no way to declare array of any type?
I don't understand and hardly to believe TEI has such limitation.

Well its not a bug because VariableInfo takes a class name as a parameter

Hi Jen,
--From the dtd

The context-param element contains the declaration of a web
application's servlet context initialization parameters.
--
!ELEMENT context-param (param-name, param-value, description?)
--this are parameters that apply to the application scope it looks like
to me
!--
The web-app element is the root of the deployment descriptor for
a web application
--
!ELEMENT web-app (icon?, display-name?, description?, distributable?,
context-param*, servlet*, servlet-mapping*, session-config?,
mime-mapping*, welcome-file-list?, error-page*, taglib*,
resource-ref*, security-constraint*, login-config?, security-role*,
env-entry*, ejb-ref*)
in your app grab the values from the application scope.
Let us know if it works for you.

Bug of RC2? - About Javac instantiating

Orion behavior of getWriter() in JSP
Orion JSP seems take getWriter() method as illegal, but it works fine on JSWDK, Tomcat, JRun, WebShpere, or Resin. So, I think this is a mis-behavior of Orion JSP. Did JSP Spec descript about this ?
RE: Bug of RC2? - About Javac instantiating
Sorry for my unclear Bug report, but the error message is very odd, of cause, I have copy tool.jar to orion lib directory, in fact the same configuration works fine just under RC1, so this should not my fault, this should be a strange bug. The error message just report on auto-recompile servlet not report on JSP complie and just show Internal error 500. Now, I use jikes instead sun javac, it works, but jikes don't support i18n. Although the new version of Jikes support i18n, but you have to give the encoding, but because Orion configuration can't set any parameter to jikes, so it still cant support i18n.

Primary Key and OR-mapping - use String
Can somebody give sugesstion in EJB how to use String as primary key and cmp-field? Some database dont' allow too larg varchar type to be primary key but if I set the String OR-Mapping to small, the String langth will be limit on other EJB cmp-field, I know build my table by hand, by is there any better idea?

BUG: Taglib dont support double byte character set
the taglib seems can't handle i18n correctly, for ex: test:loop count="10" ¤¤¤å /test:loop it works fine, but if the body of taglib is a dynamic body, ex test:loop count="10" %="¤¤¤å"% /test:loop it works incorrect.
behavior of encodeRedirectURL()
the encodeRedirectURL() is used when you generate a dynamic url without cookie support. encodeRedirectURL() in Orion will always generate session id , but I think it should be use only when the cookie is disable.
Bug of Taglib and many i18n issue of Orion JSP
Taglib can handle i18n correctly. If I want use Big5 for my JSP page enocoding, according I have to set %@page contentType="text/html;charset=Big5" otherwise the dynamic string, ex %="¤¤¤å"% won't be correct. I find Orion handle it fine, but if in taglib body , it goes wrong. This perhapers the taglib out put stream use the io stream that don't support i18n. NOW I have serveral suggestion to orion, hopes the orion team can look the JSP i18n issue otherwise the orion can't deploy to the double byte enviroment. 1. use the system default encoding (file.encoding)be the JSP content-type encoding to ease development. So I dont need to type %@page contentType="text/html;charset=Big5" on every JSP page. 2. use the content-type to parsing the JSP to let JSP support multi-language 3. allow user to set JSP encoding in the orion web config 4. fix the TagLib and POST/GET value i18n problem
POST value encoding problem
Orion JSP/servlet has the POST problem, that many JSP/servlet engine have already fix long time ago. I am amazing that Orion havent found this bug. If Orion use the java.net.URLDecoder to parse the Form data, the post valuse won't support i18n. Make a new URLDecoder and parse data according the contentType of JSP page, replace the java.net.URLDecoder could fix this bug. The best jsp engine support i18n that I have seem is Resin of caucho.com, hope Orion can be as good as it.
Does Orion really support clustering?
the document says orion support jsp/servlet clustering. but I cant figureout how to setup a clustering server. Doest orion really support clustering or just going to ? Please give me a clear answer, thanx.
