escape characters in #set
Hi!
i writing a template for ANT, with a lot of ${..}, and
i found a little problem:
set ( $myvar = "\${project}")
because i want my $myvar contains "${project}" without
be used by velocity.
this cause an error:
org.apache.velocity.runtime.parser.TokenMgrError:
Lexical error at line 23, column 15. Encountered: "$"
(36), after : "\"\\" at
org.apache.velocity.runtime.parser.ParserTokenManager.getNextToken(ParserTokenManager.java:3496)

the workaround is:
set ($usd = "\$")
set ( $myvar = "$usd{project}")
Thank you,

Velocity FileResourceReader, How do I obtain the path and filename used ?
Posted by "Gerald E. Bennett" <mr...@austin.rr.com>.
When obtaining a template, if the resource is a FileResourceReader is there
a way to obtain the extended filename ?
If not could this be added somehow ?
I have tried the following in my code except not sure what to do for the
"??":
ResourceLoader resourceLoader=template.getResourceLoader();
if(resourceLoader.getClassName().endsWith(".FileResourceLoader"))
{
System.out.println("Parsing...");
System.out.println("FileName:" +?? +"\nFilePath:"+??);
}

Re[2]: Velocity on weblogic
Posted by daljeetsingh <da...@softhome.net>.
Weblogic has these three folders setup at installation:
public_html: Put ur JSP/HTML etc
serverclasses: Put ur beans and other non reloadble classes
servletclasses:Put ur servlets here.
i have tried to put Web-inf in all the above folders. Doesn't help. With
the contexts it works, I have installed the war files that come with
struts. So within web applications it understnads the web-inf folder.
Thanx

That sounds fine. Maybe it does work.
What if I am already into a project that doesnot use contexts as they
are in TOMCAT. Just want to use velocity with the existing application.
There are a lot of people who will be in a similar position.
We have an app that already works under the default folders and doesnot
use contexts. Maybe I need to port this somehow.
But i will keep u posted.

You'd think you would get good documentation for US$30,000.00 per
processor...
Hm. Looking at it, they aren't bad.
http://www.weblogic.com/docs51/classdocs/webappguide.html
Here's what I am guessing you will have to do...
1) setup a directory for your web app. Assuming unix :
/opt/mywebapp
/opt/mywebapp/templates
/opt/mywebapp/WEB-INF
/opt/mywebapp/WEB-INF/lib
/opt/mywebapp/WEB-INF/classes
where 'mywebapp' is the name of the webapp. And it doesn't have top be
in /opt
2) Put the velocity-XX.jar into mywebapp/WEB-INF/lib above
3) Put the SampleServlet.class into the mywebapp/WEB-INF/classes above.
4) Put a web.xml with the following you have been quoting into
mywebapp/WEB-INF
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2.2.dtd">
<web-app>
<servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>SampleServlet</servlet-class>
<init-param>
<param-name>properties</param-name>
<param-value>velocity.properties</param-value>
</init-param>
</servlet>
</web-app>
5) Put sample.vm into mywebapp/templates
6) make a file velocity.properties, place in mywebapp/ and make it
include the line
file.resource.loader.path=/opt/mywebapp/templates
runtime.log=/opt/mywebapp/velocity.log
7) In the weblogic.properties file, add the line
weblogic.httpd.webApp.mywebapp=/opt/mywebapp
8) Bounce or start weblogic.
If this does indeed work, please, please, *please* let me know, so we
can document this in our docs. I will also provide a WAR somewhere to
make this easier for people.

Hello,
U see my problem I dont even know where this folder goes under weblogic
5.1
It has public_html, serverclasses and servletclasses. I kept Web-inf in
all three with a web.xml that contains:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2.2.dtd">
<web-app>
<servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>SampleServlet</servlet-class>
<init-param>
<param-name>properties</param-name>
<param-value>velocity.properties</param-value>
</init-param>
</servlet>
</web-app>
but i still cant access the servlet SampleServlet as MyServlet. I can
though access SampleServlet.
Will look further and let u know.
Thanks

nope - it's just that the example seemed a good place to start :-)
the example in the documentation didn't work for me so i had to modify it (a
little).
thought you might as well have the results since you don't have an example at
the moment.
i'm actually working on some stuff with regard to using texen to generate java
classes (to be used in ecs, as it happens).

It's an active part of the Velocity project. If you are referring to

Both. I would say that texen development questions can go to velocity-dev.

I am actually a little startled that you can't use a web.xml deployment
descriptor in WebLogic. Reading the Servlet Spec 2.2, page 44, pte
pretty clear that
WEB-INF/web.xml
is part of the spec.
Have you tried it? There may be some implementation issues in WebLogic,
but if you could try this, we are very interested in seeing it work for
you, and selfishly, getting this information into our documentation.

Re: Velocity on weblogic

Hello,
Well now I was able to change the default properties file and place the
vm files in the correct place. One question still remains that where in
weblogic 5.1 we can put these settings:
<servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>com.foo.bar.MyServlet</servlet-class>
<init-param>
<param-name>properties</param-name>
<param-value>velocity.properties</param-value>
</init-param>
</servlet>
In TOMCAT they go into the web.xml file. Any ideas where it goes on
weblogic 5.1
Otherwise it seems to be running well.
Thanks,

Velocity on weblogic
Posted by daljeetsingh1 <da...@softhome.net>.
Hello,
Can anybody describe the installation procedure for velocity on weblogic
5.1 server.
The problem is where do the following things go
1. velocity.properties file
2. Templates
3. Also since there is no web.xml file where will I write the following
(from velocity user guide)
<servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>com.foo.bar.MyServlet</servlet-class>
<init-param>
<param-name>properties</param-name>
<param-value>velocity.properties</param-value>
</init-param>
</servlet>

Velocity won't interpolate values in a string literal if you use single
quotes. Is that what you mean?
I'll take a look at the parser error, but the above I think is what you
want to do.
