Getting the webapp name in Custom tag?

Hi,
I have a custom tag that dispalys some search results, and at the bottom of the results is a link to a controller servlet to go ad get more results to display. (Sounds bad I know but the search is very quick).
I would like this tag to be used in webapps of different names, and so need to know the web app name to build the link.
I can use pageContext.getRequest().getRealPath(""), and chop the webapp name off the end, but I was hoping for a nicer solution?
My Tag extends TagSupport.
Thanks
James

((HttpServletRequest) pageContext.getRequest()).getContextPath();

How can I use evaluate to get the instance variable in customized tag

1.
At first , I create a class called bean,and declared several params in it and do not define any getter function for the param.
class bean{
String param = "test";
SomeClass scObj = new SomeClass();
2.
The second ,I use
request.setAttribute("beanObj",new bean());
3.
And then I wanna use the customized tag to show a text box , then initialize it's value.
<salt:text name="param" value="beanObj.param">
<salt:text name="obj" value="beanObj.scObj.func()">
4.
I tried the evaluator provided by JexlContext ,Struts, JSTL and it seems that if I do not define the getter for the variable ,I can not get the bean's instance variable's value.
Expression e = ExpressionFactory.createExpression( value );
JexlContext jc = JexlHelper.createContext();
jc.getVars().put(strInitBeanName, request.getAttribute("beanObj"));
Object obj = e.evaluate(jc);
the result of the obj is null....
Can anybody recommand some other evaluator can get the value of a instance variable from an object?

do you have any other suggestion ? Nops, somebody else may have though. AFAIK, all lookups of the type
beanName.propertyNameuse reflection on the getXXX() methods to access the property.
Having said that, I guess you could write one though in a custom tag, using the same - reflection (you will ahve to rely on the java.lang.reflect.Field class quite heavily) - but that would be reinventing the wheel for most other functionality that you would have to include (like looking up the bean in scope etc)

How do I get the file names on a customized proof sheet?

How do I get the file names on a customized proof sheet?

Actually, I really don't know what you say.
But when you see the properties of a file in Windows, you can see there are two file size. One is called "SIze" and the other one is called "Size on disk".
Therefore, I would like to know the size on disk but not just the size.

Getting the folder name of the service in Tomcat 5.5

Hi,
I am using Tomcat 5.5.
I have a problem getting the folder name my service is located in.
Ex.
\webapps\myApp\...
Here i would like the string "myApp" - does anyone know how to get this?
The reason for this is that i use a war file to deploy "myApp". I have a set of properties which i don't want to change so I put them in a file outside "myApp" called "myApp.properties". I can then easily change between a test environment and my online environment.

I don't think you understand his answer.
Reading properties files from the file system directly is a mediocre solution at best for a web application. Even if it happens to work in this particular situation.
For example you would be better off loading properties from a single properties file as classpath loaded resources and simply using the context as a key to the properties in question. You could also configure this from web environment parameters specific to the web application.
Anything that puts a hard dependency on a particular file system layout is a bad idea, anything that reads files from within a web application server is likely to be a brittle solution.
This may work, for you, in your current circumstances, but you need to understand why this is a poor approach in general.

How to get the JNDI name of an EJB from within itself

Hello,
I'm trying to find a way to get the JNDI name of a session bean from
within itself.
In the application I'm working on we need to support multiple
customers. In order to do that, each EJB has a normal home and remote
interface, a base class bean implementation and different children
bean implemetations for each customer (when the logic for the
customers is different). JNDI is used to get the proper implementation
based on the customer.
I've got an EJB that provides some services that are the same for all
customers, except for the fact that it contains one variable that
should have a different value depending on the customer. I don't want
to creat subclasses just for that. What I want is to be able to get
the JNDI name and set the variable based on the it.
Is there a way to get the JNDI name for the EJB from within itself?
TIA
MJ

How to get the Full Name from NT realm

I need to get the full name of the logged user not just the username. I get
the username defined in NT by request.getRemoteUser(). I need to get the
full name defined in NT server.
Thanks
madhu

Hi Madhu,
There are no apis to do this with WebLogic.
What I recommend is to do some JNI with Java
Create some custom class which retrieves the nt username and then makes calls to
microsoft libraries to return the full name.
I have no idea what these calls to microsoft libraries will actually be --
you'll probably have to do some research to see how to retrieve full usernames
from NT -- what libraries you need to use, etc.
Good luck.

I really liked your audit table concept. You inspired me to modify it so that, the entire recordset gets captured and added a couple of other fields. Wanted to share my end result.

How can I get the host name from Email address?

hi
When I using socket to develope an email-sending servlet,I don't know how to get the host name from emial address.can you help me,thanks

Stripping off the user name will give you the domain of from field in the message. This is not the same as the host. Take a look at:
http://www.stopspam.org/email/headers/headers.html
Theres a pretty good discussion about email headers and how to use the information. You probably want to check the information here against the RFC.

How can I get the path name and rename it?

I Hope someone who knows more about automator than I can help me out here. What I'm trying to do is get the path file name, while also changing part of it. Here is my example:
I can get the path name with this "Get Path" script I found http://automatorworld.com/archives/get-path/all-comments/
It does half the job so I just need to tweak it but know how. When I get the path this is what I'll get: /Volumes/Public/Creative Services/Campaigns/2010/NCDDiv-32CDV Upgrade/NCDDIV-32Versions.xls
I need to remove the beginning part"/volumes" to "file://///nhmanmkt01"
This is so I can send the path from our sever where we keep our files to my windows friends so they can open it.
Thanks for any help you can provide!

ok, make the following workflow.
1. get selected finder items.
2. run shell script

font-size: 10px;
margin: 0px;
padding: 5px;

title="this text can be pasted into the Script Editor">
for f in "$@"
do
echo "$f"|sed 's%/Volumes%file://///nhmanmkt01%'
done</pre>
set the script to accept input as arguments
3. copy to clipboard
save it as a finder plugin.

How to get the table name and bind columns names in an INSERT statement ?

I have an INSERT statement with input parameters (for example
INSERT INTO my_table VALUES (:a, :a, :a)) and I want to know
without parsing the statement which is the name of table to
insert to and the corresponding columns.
This is needed to generate the SELECT FOR UPDATE statement to
refetch a BLOB before actually writing to it. The code does not
know in advance the schema (generic code).
Thanks in advance,
Joseph Canedo

Once you have prepared your statement, you can execute the
statement with the OCI_DESCRIBE_ONLY mode before binding any
columns. Then you can use OCIParamGet to find out about each
column (column index is 1-based). You should get OCI_NO_DATA or
ORA-24334 if there are no more columns in the statement. Note
that the parameter descriptor from OCIParamGet is
allocated/freed internally by OCI; you do not need to manage it
explicitly. The parameter descriptor is passed to OCIAttrGet in
order to obtain for instance the maximum size of data in the
column OCI_ATTR_DATA_SIZE. You can also get the column name in
this way, although I do not remember the #define off the top of
my head. Getting the table name appears to be much more
difficult; I have never had to do that yet. Good luck. -Ralph
