[Lift] Re: File Download

[DavidV]

I have recreated a number of StreamingResponse methods from both the
Loop link above and the Lift book and I still can't seem to get the
desired effect.  I have been able to get a PlainTextResponse to work
by using LiftRules.dispatch in the Boot, like so:

LiftRules.dispatch.prepend {
  case Req(("analysis" :: "inprocess" :: Nil), _, _) =>
() => Full(PlainTextResponse("test"))
}

However, I am unable to get any sort of streaming response to work in
the particular snippet which contains the data I would like to use.
Here are some of the methods I've tried:

  def textResponse: Box[LiftResponse] = {
println("TEXT RESPONSE")
val ab = "text would go here"
Full(PlainTextResponse(ab,
  ("Content-Type" -> "text/plain") :: Nil, 200
))
  }

  def streamingResponseFile: Box[LiftResponse] = {
println("STREAMING RESPONSE FILE")
val file: File = new File(
"C:\\Source\\trunk\\eclipse\\testLift\\src\\main\\webapp\\images\
\ultra.png"
)
val length = file.length
val fileInput = new java.io.FileInputStream(file)
Full(StreamingResponse(fileInput,
  () => { fileInput.close },
  length,
  ("Content-Type" -> "image/png") :: Nil,
  Nil,
  200)
)
  }

Do I have to make a LiftRules.dispatch function in the Boot in
addition to the StreamingResponse in my snippet?

I am trying to download plain text, but it is variable and dependent
on some parameters and other variables in the particular Snippet
class.  Would I have to pass that data into the boot method in order
to get the desired response?  I would prefer to handle it entirely in
the snippet itself.

Finally, I'm not really sure how exactly to handle the
Full(StreamingResponse) once I have created it in order to actually
download the data and save it to the client computer.  Although I
assume the browser will handle this one I've formatted the Response
correctly and actually have it working.

Thanks again,
David

[Lift] Re: File Download

[DavidV]

I am also looking to download a file from the server that is hosting
my Lift web app.  There is a very useful fileUpload method in the
SHtml class and I was wondering if there may be something similar for
a file download?  I was unable to find anything, and searching for
"Lift" or "Scala Lift download" on Google returns nothing but pages to
download the libraries, plugins or source code.  I suppose I could use
the StreamingResponse, but I am already saving the file I need to the
server and it would be nice to be able to download it to any client
computer with the typical "Browse" button, similar to the upload,
Thanks,
David

[Lift] Re: stateful submit

[DavidV]

Capturing the value depends on reading it from the URL as a parameter,
so even if it's local, after I submit the form and the page reloads
without the "id" parameter in the URL, I still get the None.get error
because it is trying find a parameter that isn't there.  I need some
way to keep the parameter in the URL after the form is submitted...

[Lift] stateful submit

[DavidV]

I have searched a number of threads and have found similar posts but
nothing the exactly answers this relatively simple question.
I am using the Lift submit method (net.liftweb.http.Shtml.submit) to
submit a form.  Upon submission, I want to execute another method
called getImgs(s: String), so I have set up my submit button as so:

def chooseIndex: NodeSeq = {
...
{submit("Metabolic Reserve Index", () => getImgs("met"))}
...
}

In my .html file for this page I call the snippet with form="post"


The getImgs method has a variable that relies on a URL parameter that
is lost when I click the submit button, so my S.param("id").get
returns a None.get error.  How can I retain the parameter through the
submit process?  Is it best to use a StatefulSnippet?  Can I read in
the parameter as an attribute?  I feel like like there are a number of
ways to accomplish this, but what is the best, or most "lifty" way?

Thanks,
David

[Lift] Re: problems with tomcat

[DavidV]

Update:
The tomcat incompatability with the external server was caused by a
Java version mismatch.  I was compiling my scala code with a newer
version of the JDK.  I had an older JDK installed on the external
server and this was causing a problem with some of my class files (but
not others, oddly).  Anyway, I updated my JDK version on the linux
server and now the website is working correctly.  Thanks for all the
help!

[Lift] Re: problems with tomcat

[DavidV]

I skipped the Test portion of mvn package by removing the testCompile
goal from my pom file under the maven-scala-plugin.  War packaging is
now working correctly, but the webapp still isn't deploying on the
remote Tomcat server...will keep at it and will post my solution if I
find one...  I think it still has to do with my database connection

More specifically, I am trying to follow the stack trace to lead me to
some sort of URL so that I can see where and why this connection is
trying to be made.  I'm not sure why the AppTest needs to make a
connection in the first place.  Can I just skip the Test portion of
the mvn package command?  Or do I have hard code the proxy settings
somewhere other than in my maven settings.xml file?  I'm still
struggling with this problem...

[Lift] Re: problems with tomcat

[DavidV]

For the time being I have code that compiles correctly and I am
leaving eclipse completely out of the picture.  I am running Windows
Vista 64bit. I have quit eclipse and tried to run a "mvn clean
install" to rebuild my project, but I get the exact same error that I
previously posted (ConnectException) regarding the AppTest failure
when the install command executes the "TESTS".  Therefore, the build
fails.
...

Running net.genomas.lift.test.AppTest

If I run the project with "mvn clean tomcat:run" it works fine because
it doesn't execute the "TESTS" step.

I think that my problems with remote tomcat server may stem from
eclipse messing up the correct maven packaging of the .war file.  I'm
still trying to figure out what is causing this ConnectException
whenever AppTest.scala is executed that is preventing me from
performing a normal "mvn package"

I am working behind a firewall that is important for the security of
our data where I work, so it cannot be disabled.  I also work behind a
proxy but I have configured the maven settings.xml file to get past
the proxy, and that definitely works because I am able to
download .jar files, etc from the internet when I update to newer
versions of scala/lift.

I would like to be able to run "mvn clean package" successfully
without using eclipse at all to ensure that I am getting a correctly
configured .war file.  This may be the reason that I am having trouble
deploying to Tomcat.  Any ideas regarding how to fix this connection
failure?

Thanks,
David

[Lift] Re: problems with tomcat

[DavidV]

Another potentially helpful detail is that I get the same liftFilter
error when running on a local jetty server through maven as I do when
running on tomcat (also through maven).  I am executing a clean
command before running the web app each and every time.

This seems more consistent with whatever is happening on the external
tomcat server...
Thoughts?  Also, any ideas about the test failures during the mvn
clean package command?

Thanks, I finally feel like I'm getting somewhere now!

[DavidV]

On a side note, while I'm installing Lift 1.0.2 with Scala2.7.5, I
always execute a "clean" command before the mvn package.  However, I
also need to execute a "clean" in eclipse before the mvn package works
properly.  Otherwise, I get this error:

[Lift] Re: problems with tomcat

[DavidV]

I don't appear to have any conflicting jars in my TOMCAT_HOME/common/
lib folder, however, I am now realizing that I have a postgres
jdbc3 .jar file in there and I am using a jdbc4 .jar postres file in
my webapp.  Perhaps that is the problem?  I'll check that out.

I am using Lift 1.0.1 with Scala version 2.7.5
It does work with the tomcat on my computer, which leads me to believe
that it should be compatible with the current versions of Lift/Scala
that I'm using.  Maybe that's an incorrect assumption though, as I'm
not very familiar with tomcat.

[Lift] problems with tomcat

[DavidV]

I am having some issues deploying my Lift web application to a tomcat
server.
When I run tomcat through maven (mvn tomcat:run), the web application
works properly and connects to my postgres database.  However, when I
use mvn package to create a war file which I then deploy to a local
tomcat server (on my computer) only the HTML of the web application
appears and the snippets with the application's content fail.  It
appears to be a problem with the sitemap loading properly, because I
changed the sitemap by deleting one of many Loc.If parameters and the
web application then worked as expected.  However, when I then tried
to deploy the same .war file to a tomcat server on a different
computer, the web app failed again, showing only the HTML and not the
snippets.  I suspect that perhaps this is because I need to change my
url to the postgres database, but I've tried many permutations of the
url and none seem to work.
To make things worse, the logging doesn't seem to be working properly
making it difficult to diagnose the exact problem.  I can't locate a
stdout.log file anywhere.  In my catalina.out file I get the following
error:

java.lang.NullPointerException
at scala.runtime.BoxesRunTime.boxToInteger(Unknown Source)
at scala.actors.Actor$$anonfun$scala$actors$Actor$$seq$1.apply
(Actor.scala:800)
at scala.actors.Actor$$anonfun$scala$actors$Actor$$seq$1.apply

(ThreadPoolExecutor.java:650)
at java.util.concurrent.ThreadPoolExecutor$Worker.run
(ThreadPoolExecutor.java:675)

I also get an error that says:
log4j:WARN Please initialize the log4j system properly.

Do I need to configure log4j in order to get the stdout.log file?

Any ideas of what might be going on here?

Thanks,
David

[Lift] Re: Announcing 1.0.1!

[DavidV]

I am running Scala 2.7.5 final and would like to upgrade to Lift
1.0.1.  I have never upgraded my Lift before (still running 1.0) and
am not sure how to do it without creating a new project.  I using
Maven and the jetty server to compile my lift code.  I know how to
modify a .pom file and some basic command prompt maven commands.  Can
I use mvn install, or mvn update or something similar?  I'm sure this
is very straightforward and easy but am having a hard time figuring it
out and certainly don't want to mess up my webapp.
Thanks and looking forward to working with 1.0.1

[Lift] Mapping MappedDouble to Postgres database

[DavidV]

I am trying to map a MappedDouble object to a postgres database and I
get the following error:

Exception in thread "main" org.postgresql.util.PSQLException: ERROR:
type "double" does not exist

I am looking through the Schemifier to try and figure out where the
database type is assigned and how to override it.  Postgres has a
"real" type which would be appropriate for the DB columns I am
creating.

Can anyone help me in converting the MappedDouble to create a DB
column of type "real" in postgres?

Thanks,
David

[Lift] Re: syntax question

[DavidV]

Sorry for the confusion.  The way I initially represented the table,
it did not compile.  I got the following errors:

in XML literal: '>' expected instead of '0'
in XML literal: '>' expected instead of '0'
in XML literal: expected closing tag of -
in XML literal: expected closing tag of -

on lines: 3, 5, 8 and 10, respectively.

1 def resultTable: NodeSeq  = {
2  
3   for (r <- 0 until analysis.slots.length) {
4 
5 for (c <- 0 until test.testvars.length) {
6   new CellType(calls(r)(c).output)
7 }
8 
9   }
10   
11  }

I have tried a number of different ways to add the curly braces that
makes it compile, including they way you suggested.  However every
time I succeed in making it compile with curly braces it returns an
empty table.

[Lift] Re: syntax question

[DavidV]

Like this?

def resultTable: NodeSeq  = {
  
  {for (r <- 0 until analysis.slots.length) {

{for (c <- 0 until test.testvars.length) {
  new CellType(calls(r)(c).output)
}}

  }}
  
  }

that is not working for me either, it still returns an empty table...

can you by any chance demonstrate by editing this table?


  
for (c <- 0 until 10)  {
   {array(c)} 
}
  



thanks,
David

[Lift] syntax question

[DavidV]

This may be more of an HTML question, but since I haven't found an
answer online, I'm working in Lift and I'm sure most people here can
answer this easily I figured I'd ask.

I am trying to create a dynamic HTML table, by looping through the
rows and columns of the table and inserting variables from a two-
dimensional array.

my array is "calls" and is an Array[Array[Result]]

The basic structure of the table that I want to create is:

def resultTable: NodeSeq  = {
  
  for (r <- 0 until analysis.slots.length) {

for (c <- 0 until test.testvars.length) {
  new CellType(calls(r)(c).output)
}

  }
  
  }

I have a class CellType that returns a  variable content 

The resultTable method is in a snippet class and I am calling it from
a separate HTML file.  All other mechanisms are working well since I
tested a simple TEST within the same method and it
created the table as expected.  Therefore, this is simply a syntax
error.  I know you have to use {} to isolate scala code/variables in
HTML, but I'm not sure how to do that when the brackets are necessary
for the loop.

Thanks for the help,
David

[Lift] lift request param

[DavidV]

For the laboratory website I am building I need to keep track of
batches of samples as they are being processed, and would like to do
so with a request parameter in the URL.  Right now, I am manually
adding this parameter to every link:

object batch extends MappedLong(this) {
override def displayName = "Batch"
override def asHtml: Node = http://groups.google.com/group/liftweb?hl=en
-~--~~~~--~~--~--~---

[Lift] Re: simple syntax question

[DavidV]

For now I have fixed the problem by calling a new method in my snippet
that accesses the variable with { } in the input tag.  I would be
interested to know if there is a way to do this with a bind tag
directly in the  tag in the .html file, because I feel like my
current solution is a bit of a kludge...

[Lift] simple syntax question

[DavidV]

I would like to include a variable value in an  tag in my .html
file.  I have defined a tag as follows:

  def upload(xhtml: Group): NodeSeq =
if (S.get_?) {
  bind("ul", chooseTemplate("choose", "get", xhtml),
"file_upload" -> fileUpload(ul => theUpload(Full
(ul))),
"batch" -> currBatch
  )
}

thus,




returns the variable value that I need

How can I retrieve this variable for the "value=" attribute of my
input tag?  For instance, right now I am trying to do it like this:
 />

but that is not working.  It also doesn't work like this:

[Lift] Re: file upload

[DavidV]

I was able to find the code and have a program ready to parse the
files as soon as I can upload them.  I tried writing my own version of
the code found here:
http://github.com/dpp/liftweb/blob/dcc7b064a42832b06e4523d1a35351967d7a46b2/sites/example/src/main/webapp/file_upload.html
but I got the following error when I tried to load the page on my
browser:

XML Parsing Error: prefix not bound to a namespace
Location: http://localhost:8080/analysis/inprocess
Line Number 78, Column 1:

^

I am not sure what "choose" is or where to find it and am having
trouble finding documentation online.  I am still working with
Lift-1.0, could this be the problem?

Thanks,
David

I would like to upload a .csv file onto the web server so I can then
parse it in my webapp, and put certain fields into my database.  I
would like a "Browse..." button, much like the one shown on this Lift

Can anyone point me in the right direction as to how to get started
doing this, or tell me where I can find the example code for the link

[Lift] Re: NULLable MappedForeignKey

[DavidV]

As you can probably tell from the question, I'm still a beginning
programmer and just learning Scala/Lift, however, I do have a basic
understanding of the difference between option types and null
references.  In this particular case, there are definite cases where
the field will be assigned a value and others where it will be empty,
thus I will set it as Empty where appropriate following David Pollak's
instructions.
Thanks

[Lift] Re: Menu widget

[DavidV]

I posted this yesterday but I haven't seen it appear yet...sorry if it
is here twice.

I downloaded the scripts separately because I didn't know how to
update my repository/library to include the MenuWidget class and the
appropriate .js and .css files.  I tried running "mvn install" on my
webapp, but it didn't download those new files.
I fixed the problem with my .css file so it compiles now, however I'm
still not getting the nice stylish superfish navbar.  Instead, I'm
getting a vertical bulleted list of links to my different pages.  I
think it's a problem with my template.  Here are the relevant
sections:

I figured out what I needed by checking out the "counting" link on the

appreciate it.

[Lift] Re: Menu widget

[DavidV]

I would like to use this new MenuWidget, so I got the source code from
GitHub and put it into my application as a snippet.  I also downloaded
all of the necessary superfish .css and .js files from the superfish
website and put those in local sub-directories of the "src/main/
webapp" folder.  When I try to compile the code in maven, however, I
get the following error.

Does anyone know where I could find some example code of SessionVar or

SessionVar or a RequestVar so that I can maintain and update the value

[Lift] Re: MappedTextarea problem

[DavidV]

As Tyler suggested, I would like to create my own style sheet for my
webapp.  My app is currently using the blueprint CSS boss, but I can't
find the screen.css file anywhere on my computer.  Is it being called
from within a jar or war file?  I can access it by putting the URL in
my web browser, but then I can't find the directory in windows
explorer.  I used firebug and confirmed that I can fix this problem by
altering the css style sheet.  How can I create my own and where
should I store it in my project folder?
Thanks,
David

[Lift] Re: MappedTextarea problem

BlueprintCSS is indeed the CSS boss for my app.  I'd like to add my
own style-sheet as Tyler suggested, however I can't seem to find the
screen.css file anywhere on my computer.  The directory that it points
to (/classpath/blueprint/screen.css) does not exist in my project
directory.  Any ideas on where this file is located or how I can go
about making my own style-sheet and where I should store it in my
project?
Thanks,

[Lift] access object field after snippet form submission

[DavidV]

In the webapp I'm working on, I have three separate forms (snippets)
linked to three separate objects.  I would like to maintain a link
between the objects through ID fields, since all three forms contain
information pertinent to one individual record.  The problem is, after
I submit the first form I can no longer access its ID field from the
second form.  So, when I try to use a MappedLongForeignKey to link the
two objects, the field is blank in the database.  Is there any way to
either access the ID field value from the first form after it has
already been submitted and saved?  Is there a way to save the values
after submission of the form without using a StatefulSnippet?
If this is unclear let me know and I'll include some actual code to
better explain what I am trying to do.
Thanks,
David

[Lift] MappedTextarea problem

[DavidV]

For some reason when I override the textareaRows and textareaCols
methods in MappedTextarea, the size of the text block appears the same
in my web application no matter what size I assign to the rows and
cols.  Does anyone know how to decrease the size of the blank text
area that shows up on the webpage?

[Lift] Re: populate DB table upon creation

[DavidV]

I mentioned that I would post the final code once I worked out all the
bugs, so here is what I came up with:

object SampleType extends SampleType with LongKeyedMetaMapper
[SampleType] {
  override def dbTableName = "sample_type" // define the DB table name
  val choices = SampleTypeList.names
  def writeToTable(c: SuperConnection) (cmd: () => String) {
val makeSql = cmd()
val st = c.createStatement
st.execute(makeSql)
println(makeSql)
st.close
  }

  override def dbAddTable = {
DB.use(DefaultConnectionIdentifier) {
  con =>
val connection = con // SuperConnection(con)
  val driver = con.calcDriver
(connection.getMetaData.getDatabaseProductName)
  Full(
() => {
  for (i <- 1 to choices.length) writeToTable(con) {
() => "INSERT INTO "+dbTableName+" (id, name) VALUES ("+i
+", '"+choices(i-1)+"')"
  }
}
  )
}
  }
}

Hope that helps anyone with the same problem in the future.

[Lift] populate DB table upon creation

[DavidV]

I wondering how to populate rows of a DB table upon it's creation.
First, where in the lift code are tables created?  Is it in trait
BaseMapper's dbAddTable method?  I have an Array[String] I would like
to add to the table when it is being created.  Which method can I
override to achieve this and how should I do so?

Thanks!
-David

[Lift] Re: Help on getting Eclipse/Maven/Lift working

[DavidV]

Hi Thomas,
I've been having the same troubles and found that these instructions
helped me a bit:

http://liftweb.net/index.php/Using_eclipse_hotdeploy

if you left-click on the RunWebApp application and go to "Debug As"
and don't see an "Open Debug Dialogue" option, just try clicking on
"Scala Application"...that worked for me.

Good luck!
-David

[Lift] Lift 0.10 example code

[DavidV]

Is there Lift example code, compatible with the 0.10 version library
that is more robust than the lift-blank and lift-basic archetypes
highlighted here:
http://liftweb.net/index.php/Archetypes

I'm looking for something more like the demo available from liftweb:
http://demo.liftweb.net/

Thanks,
-David

[Lift] Re: [ANN] Compiling Lift with Scala 2.7.2.RC2 and Eclipse Plugin

[DavidV]

I followed the instructions outlined by Jorge exactly and everything
seemed to be working fine, but I got the following error when trying
to create the liftweb git repository as outlined in Step 1:

...walk a4ce14468f18844414e001f3353b93bfb3250b91

fatal: Fetch failed.

the repository was not fully created as evidenced by the error that
came when I tried to go on to Step 2:

[EMAIL PROTECTED] /c/Source/Lift
$ cd liftweb

[EMAIL PROTECTED] /c/Source/Lift/liftweb
$ git checkout master
fatal: Not a git repository

Any ideas on how I can bypass this problem?  I don't even know where
to start at this point.

Thanks,
David

[Lift] Re: [ANN] Compiling Lift with Scala 2.7.2.RC2 and Eclipse Plugin

[DavidV]

I'm using the latest version - 1.6.0.2 for windows.  I got it from
this website:
http://code.google.com/p/msysgit/downloads/list

I figured it was OK since all the versions are listed as "Beta"...
