Subject difference between Thread.currentThread().getContextClassLoader() and this.getClass().getClassLoader()
Date Tue, 22 Jul 2003 03:54:48 GMT
Hi,
      When I was debugging the code and verifying the log. I found the code
snippet mentioned below is behaving erratically in iPlanet/Sun ONE Web
Server. I  have no idea what is the purpose of the following code and why
it should behave differently in two different web servers.

PropertyMessageResources.java

        ClassLoader classLoader = Thread.currentThread
().getContextClassLoader();
        if (classLoader == null) {
            classLoader = this.getClass().getClassLoader();
        }

   If I change the code as mentioned below, it works. This is the code
which was there in struts 1.0.2.

       ClassLoader classLoader = this.getClass().getClassLoader();

   And wherever this code block is used there also it throws exceptions.

   The same code is used in the following sources also.

ActionServlet.java(437)
FormBeanConfig.java(315)
FormPropertyConfig.java(257)
RequestUtils.java(201)

   Could somebody explain the purpose of this code and why was it changed
in 1.1?

   If I change the code to 1.0.2 style will it have any impact on the
struts functionality.

Best Regards,
Thiru

          SP5 throws exception


Sometimes back i had issue with iPlanet web server 6.0 with SP1. Now my app
is running well on iWS with SP1. Am sure it should work well with later SP
versions. Did you make sure your lib and tlds are getting picked up? Take a
look at your _Welcome_jsp.java line 226 on which you are getting error in
your error trace.

Hi,

When I debugged the location of the line of messagetag.java, i
found it is not able to retrieve the message from the properties file.

But the message source has been configured in the struts-config.xml
file. I said null=true in action servet configuration, then it started
giving the values like ???en.welcome.heading???, ???en.welcome.message???.

I commented the message resouces entry in struts-config file and
added the application entry in web.xml. Still it is not picking up the
messages.

This happens only in iPlanet, in Tomcat as soon as deployed it
started working.

10:17 AM exception





Hi,

I have deployed the struts-blank.war file in Sun ONE Web Server
6.0(iPlanet) SP5. When I access the application through the URL it throws
an exception as mentioned below.

In the documentation I believe it mentions it will work in SP2+.

Please do the needful.
