Weasis help

jwest · Jan 12th 2014

Mr Marcel,

I am needing your help, please.

I am using dgate 1.4.17beta3 on conquest server and on apache cgi-bin. My JRE is 1.7

I have had a relative success deploying weasis with conquest on my sistem with informations from this post http://forum.image-systems.biz…?f=33&t=3676&hilit=weasis .

I have two remotes PC. I have a PC with conquest server and I have an other PC hosting apache and tomcat.

So I have tomcat and apache installed and working.

1. From my PC station, If I am requesting studies via tomcat server, there is no problem.
In my PC, when I use http://my_site_with_tomcat/wea…iewer.jnlp?patientID=XXXX all works well showing stuydies.

2. From my PC station, If I am using wado server via apache server I have a problem.
When I use http://my_site_with_apache/cgi…=patientid+=+%27183692%27, JRE is showing and ask for confirmation to execute the file. I agree to execute and i have an exception after.

I get this exception:
Unexpected Exception
java.lang.NullPointerException

Hi Luiz,

you need 1.4.17c to run in the web server such that the scripts work. Not sure if you need to upgrade the dicom server itself too, I guess not.

Maybe best to start with all 1.4.17c files for cgi-bin.

Marcel

marcelvanherk · Jan 12th 2014

Hi,

the entries:

[weasisseriesxml]
source = viewers\weasisseriesxml.lua

[weasisstudyxml]
source = viewers\weasisstudyxml.lua

are missing from the dicom.ini from the distribution. If you add those everything works.

Marcel

jwest · Jan 12th 2014

Mr Marcel,

Thansk for your response.

If you look at my dicom.ini I already have setttings to
[weasisseriesxml]
source = weasisseriesxml.lua

[weasisstudyxml]
source = weasisstudyxml.lua

I had put all .lua, .cq into cgi-bin.
I just created a viewers subdirectory and move all .lua and .cq files to it.

I think it make no difference the location of .lua or .cq, since thy are setting in dicom.ini correcttly. I already have weasis working and showing images when I call studies via tomcat. Eg; http://my_site_with_tomcat/weasis-pacs- ... entID=XXXX all works well showing stuydies.

I just change dgate.exe from to 1.4.17c .

To upgrade to 1.4.17c , I only substitue dgate.exe on conquest server and on my cgi-bin. Is it ok?

After it I test again and when I call studies via tomcat. Eg; http://my_site_with_tomcat/weasis-pacs- ... entID=XXXX all works well showing stuydies images.
But, If i use weasis serie viewer with dgate: http://my_site_with_apache/cgi-bin/dgat ... 7183692%27, JRE is showing and ask for confirmation to execute the file. I agree to execute and i have tyhe same exception after.

The exception occurs only with weasis series viewer via dgate.exe on apache.

I have all last files in cgi-bin, cgi-bin/viewers.

The dgate.exe on apache server and conquest server is the same as 1.4.17c .

Regards,
Luiz

marcelvanherk · Jan 12th 2014

Hi Luiz,

are these files OK?

ACRNemaMap = C:\wamp\www\dicomserver\acrnema.map
Dictionary = C:\wamp\www\dicomserver\dgate.dic

And is the servers own AE, IP and port specified in acrnema.map?

Marcel

jwest · Jan 12th 2014

Mr Marcel,

>>are these files OK?
>>ACRNemaMap = C:\wamp\www\dicomserver\acrnema.map
>>Dictionary = C:\wamp\www\dicomserver\dgate.dic
Yes, It was setting ok. I just copied these files from my other PC running Conquest Server and put them in the other PC running WAMP.
They are identical copies from files of my other PC running conquest server.

I am using firefox 26.0 with windows XP.
if I change the dicom.ini configuration to viewer = imagejaviewer all works well. But with weasisviewer, I have an exception and Weasis doesn´t load.

I also tested it with a notebook running win 7. In this case, weasis viewer is loading but no imagens are showing.

I don´t know if the next log help, but I get the next log in java console when the error occurs:

Here is the log from java console in WIN XP:

Mr Marcel,

Only as additional information, here is my acrnema.map.
On PC runnning conquest server it is in default location directory
and on pc running WAMP : C:\wamp\www\dicomserver\acrnema.map

Mr Marcel,

I have installed JRE 1.7.0_45 and JRE 1.6.0_31.

At https://groups.google.com/forum/#!topic/dcm4che/L3d_Oer2qGU and https://groups.google.com/forum/#!topic/dcm4che/bOzKxH9EH6c, I found something about this problem related for others weasis users. Here is a snippet.

"Except the Java security restrictions described here, I forgot to mention another blocking issue (since JRE 1.7.0_40) which only allows to put property in resources when starting with "java." or "jnlp." in jnlp file. This issue has been fixed since Weasis 1.1.2 and in recent versions of weasis-pacs-connector. So, it concerns only other implementations that build the jnlp file (also the old dcm4chee-web implementation), see the workaround in the updated documentation on how to build jnlp."

If this is the problem, could you provide a fix?

Thanks in advance
Luiz

marcelvanherk · Jan 13th 2014

Hi,

I indeed use an older jav. You can try to use the updated jnlp file from:

http://www.dcm4che.org/conflue…sis+from+any+environments

to create a new launcweasis.cq

And insert:

<argument>$dicom:get -w %webscriptadress%?%extra%&mode=weasisseriesxml&series=%series2%&dum=.xml </argument>

in the correct place. This should enable the workaround.

Marcel

jwest · Jan 13th 2014

Mr Marcel.

Thank you. The first part is solved. I had success loading series.

But with studies I have another problem.
I have settings in dicom.ini to
viewer = weasisviewer
studyviewer = weasisstudyviewer

[weasisviewer]
source = viewers\launchWeasis.cq
header = Content-Type: application/x-java-jnlp-file\

[weasisseriesxml]
source = viewers\weasisseriesxml.lua

[weasisstudyviewer]
source = viewers\launchWeasisStudy.cq
header = Content-Type: application/x-java-jnlp-file\

[weasisstudyxml]
source = viewers\weasissstudyxml.lua

Here is my jnlp to studies:

Hi Luiz,

I cannot see what is wrong. Can you load the xml file with the link:

http://177.43.160.62:8040/cgi-….1332978647125.1&dum=.xml

And are you are using this as a studyviewer entry in dicom.ini?

Please also post the fixed launchweasis.cq.

Marcel

I have no problem with series viewer, only with studies.

Hi,

It must be a problem in: viewers\weasissstudyxml.lua

Ni,

>>It must be a problem in: viewers\weasissstudyxml.lua

Any help will be appreciated. I know nothing about lua.

Hi,

it works for me 1.4.17c release. Is this the weasisstudyxml.lua file you use?

Marcel

Hi, Mr Marcel,

>>it works for me 1.4.17c release. Is this the weasisstudyxml.lua
I am using a copy of weasisstudyxml.lua from 1.4.17c.
I don´t understand why weasisseriesxml.lua works and weasisstudyxml.lua doesn´t work.

To locate the problem, Is possible use only parts of weasisstudyxml.lua for test?
Could you suggest something?

Here is my weasisstudyxml.lua:

Code

print('Content-Type: application/xml\n')


local patid = string.gsub(study2, ':.*$', '')
local studyuid = string.gsub(study2, '^.*:', '')
local q = DicomObject:new()
q.QueryRetrieveLevel = 'SERIES'
q.PatientID = patid
q.StudyInstanceUID = studyuid
q.PatientBirthDate = ''
q.PatientName = ''
q.StudyDescription = ''
q.StudyDate = ''
q.StudyTime = ''
q.SeriesInstanceUID = ''
q.SeriesDescription = ''
q.SeriesNumber = ''
q.Modality = ''
r = dicomquery(servercommand('get_param:MyACRNema'), 'SERIES', q)


local s = DicomObject:new()


print([[
<?xml version="1.0" encoding="utf-8" ?>
<wado_query xmlns= "http://www.weasis.org/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" wadoURL="]]..webscriptadress..[[" requireOnlySOPInstanceUID="false" overrideDicomTagsList="0x00000000">

]])


for i=0, #r-1 do
  print([[
      <Series SeriesInstanceUID="]]..r[i].SeriesInstanceUID..[[" SeriesDescription="]]..r[i].SeriesDescription..[[" SeriesNumber="]]..r[i].SeriesNumber..[[" Modality="]]..r[i].Modality..[[" >
  ]])


  s.QueryRetrieveLevel = 'IMAGE'
  s.SOPInstanceUID = ''
  s.ImageNumber = ''
  s.SeriesInstanceUID = r[i].SeriesInstanceUID
  t = dicomquery(servercommand('get_param:MyACRNema'), 'IMAGE', s)
  for j=0, #t-1 do
    print([[<Instance SOPInstanceUID="]]..t[j].SOPInstanceUID..[[" InstanceNumber="]]..j..[[" />]])
  end


  print([[
      </Series>
]])
end


print([[
    </Study>
  </Patient>
</wado_query>
]])

Nver mind, I make a typo in dicom.ini
[weasisstudyxml]
source = viewers\weasissstudyxml.lua ----> I put many "s" letters
The correct would be source = viewers\weasisstudyxml.lua

Thank you so much for your help.

I have another question. I don´t know if I need open a new topic.

Is it possible you help to setting jpeg compression to send imagens from CQ via dicom wado server to client browser.
My imagens are stored uncompressed in conquest server.

Best regards,
Luiz

marcelvanherk · Jan 14th 2014

Hi,

Great that it is solved. Can you please post both updated cq files in the weasis 'sticky' post, so that others can find them as well? In addition, the WADO server responds to compression requests, so if you ask for jpeg (transferSyntax=1.2.840.10008.1.2.4.55) in the WADO request through the weasisseriesxml file conquest should compress on the fly. You will have to lookup weasis examples on how to do that.

Mr Marcel,
>>Great that it is solved. Can you please post both updated cq files in the weasis 'sticky' post, so that others can find them as well?
Certainly, I will do. But, sorry, my English is not so good. What is 'sticky' post? Is the current post or that I change the subject adding "Solved"? Or I have to create a new topic to post the files?

>> In addition, the WADO server responds to compression requests, so if you ask for jpeg (transferSyntax=1.2.840.10008.1.2.4.55) in the WADO request through the weasisseriesxml >>file conquest should compress on the fly. You will have to lookup weasis examples on how to do that.
I am going lookup weasis examples on how to do that.
Do i have to change some configuration in dicom.ini?

Luiz
