[JBoss Seam] - s:graphicImage and s:transformImage VERY, VERY slow
by wquraishi
I've got an object of blog which contains a collection of blog_photos. The blog_photos are persisted in a mysql db as binary data. This works great. When I render the view, the s:graphicImage takes an enormous amount of time to render. At first, I thought, it was the transform but that only adds a second. Here's the code:
| <rich:dataGrid value="#{blog.photo}" var="blogPhoto"
| columns="3">
| <rich:panel rendered="#{blogPhoto ne null}">
| <s:graphicImage value="#{blogPhoto.data}"
| style="border: 1px;"
| rendered="#{blogPhoto ne null}" styleClass="boxed">
| <s:transformImageSize height="97" maintainRatio="true" />
| </s:graphicImage>
| <rich:toolTip followMouse="true" direction="top-right"
| value="#{blogPhoto.photoDescription}" horizontalOffset="-50"
| verticalOffset="5">
| <s:graphicImage value="#{blogPhoto.data}"
| style="border: 1px;"
| rendered="#{blogPhoto ne null}" styleClass="boxed">
| <s:transformImageSize height="450" maintainRatio="true" />
| </s:graphicImage>
| </rich:toolTip>
| </rich:panel>
| </rich:dataGrid>
|
| |
| | I'm sure this is the cause b/c when I comment out the code, the page renders in a second. With 12 images or so, i takes about 12 seconds.

[JBoss Tools (users)] - Problem about specifying a jndi source for eclipse hibernate
by haoniukun
Dear all,
I've just used create a project with eclipse with hibernate support.
After adding a console configuration, I fail to run hibernate code generation with the following error:
| [FATAL] DatasourceConnectionProvider - Could not find datasource: java:/comp/env/jdbc/xxxx <javax.naming.NoInitialContextException: Need to specify class name in environment or system property
| , or as an applet parameter, or in an application resource file: java.naming.factory.initial>javax.naming.NoInitialContextException: Need to specify class name in environment or system property
| , or as an applet parameter, or in an application resource file: java.naming.factory.initial
|
I'm sure that my jndi name is correct since the program works fine with tomcat.
I just want hibernate plugin generate hbm file for me.
So how can I specify an initial context for console configuration?
Any help would be appreciated and thanks in advance.
