[JBoss] Error Starting JBoss Server 5 on NetBeans
a. Problem
java.lang.IllegalStateException: Incompletely deployed: DEPLOYMENTS IN ERROR: Deployment "AttachmentStore" is in error due to: java.lang.IllegalArgumentException: Wrong arguments. new for target java.lang.reflect.Constructor expected="java.net.URI" actual="java.io.File"
b. Cause
A bug that occurs with certain specific combinations of JRE and OS versions. Basically, the JBoss config is relying on reflection to return constructors in a certain order, and in some cases this order is different, causing the exception.
c. Solution
You need to change the content of
conf/bootstrap/profile.xml
. Look for the definition of theAttachmentStore
, and change the constructor line so that it starts:<constructor> <parameter class="java.io.File">
The original version doesn't have the
class="java.io.File"
attribute.[Tomcat] Tomcat Encoding Problems
a. Problem
Queryes the database with user input (search/paging by Japanese string using GET method). The problem is that accented characters are being transformed into weird letters like
ใในใ
=>ãã¹ã
.b. Cause
By default, Tomcat uses ISO-8859-1 character encoding when decoding URLs received from a browser. This can cause problems when encoding is UTF-8, and you are using international characters in the names of attachments or pages.
c. Solution
Setting the XML file encoding and the meta tags have no effect on HTTP request/response encoding. Only the following should be minimally configured for a JSP/Servlet based web application:
-
For HTTP GET requests, configure it at server level. In Tomcat, that's to be done by setting the
URIEncoding
attribute of<Connector>
in Tomcat'sconf/server.xml
<Connector port="8080" URIEncoding="UTF-8"/> <!-- If you are using mod_jk --> <!-- <Connector port="8009" protocol="AJP/1.3" URIEncoding="UTF-8"/> -->
- For HTTP POST requests, use a filter which does a
ServletRequest#setCharacterEncoding()
- For HTTP responses generated by JSPs, set
pageEncoding
attribute of<%@page%>
on a per-JSP basis, or, better, set<page-encoding>
entry inweb.xml
for an application-wide basis - For HTTP responses generated by servlets (wherein no JSP is been involved!) use
ServletResponse#setCharacterEncoding()
- Last but not least, make sure that your source code files are also saved as UTF-8. The exact configuration depends on the editor used. In case of Eclipse, you can control it via Window > Properties > General > Workspace > Text File Encoding
