no jacob-1.16.1-x86 in java.library.path

[George]

I am testing an upgrade to Railo 4.0.2.002. Generally stuff is working a bit slower but OK. Our maps are not displaying though. When I try to access them I get this error:

Railo 4.0.2.002 Error (java.lang.NoClassDefFoundError)
Message	Could not initialize class com.jacob.com.Dispatch

I can also see these errors in the logs:

I clearly have a problem with this Jacob fellow. Anybody knows where he went?

[George]

OK. I found that there is no link to C:railo\lib which is where jacob.jar resides. I included that there and now I am getting a new error that says:

ERROR","web-0","11/29/2012","16:48:38","","no jacob-1.16.1-x86 in java.library.path"

"Generally stuff is working a bit slower but OK" 

What is slower, you can point to something? Overall performance should be increased, not decreased.

Speed has increased since I deleted and then restored all caches I had. I found a possxible bug while doing this though. It is not possible to allocate any cache to Resource and function (but that is not the purpose of this post).

I also stated previously that after I included the required path to the java env (in railo-tomcat service control) I was getting a different message. That is not the case. I entered a wrong path and that is why I was getting a different message. The mapping still does not work and Jacob still has not been initialized.

Still struggling with this one. I can tell you though that it takes much longer to initialize applications the with the previous version. That means the first start up is much slower.

What's your setup like? Are you using Tomcat?

I used a windows executable that I downloaded from getrailo.org.It includes TOMCAT server. Normally I only upload a patch but I though that for a major upgrade it would be better to run the full package.


The server is Window$ 2003 + Railo + Tomcat + MSSQL 2005 server.

ok, so one known issue with Tomcat that might be the cause of your slow startup, is that Tomcat scans the whole /WEB-INF directory tree at startup.

that means that if you have a lot of files there it might cause the slow startup.

one potential issue with Railo is the .scpt files in the /WEB-INF/railo/client folder, which can have maaaany files if you have clientManagement on with default settings.

check that folder first, and other potentially overly-filled folders in /WEB-INF

HTH,

Igal

[George]

I do not have client folder there at all. Anyway. That was not the main purpose of this post. I had a problem with the jacob library. I downloaded an official jacob dll file and replaced "jacob.dll" in "C:\railo\lib\railo-server\context\bin\" by a downloaded file: "jacob-1.16.1-x86.dll"

My com objects now seem to work fine. This is a bug in Railo and it should be looked at.

I am having the same issue on Windows 2003 Web Edition.

Diagnostics: no jacob-1.16.1-x86 in java.library.path

I will try this fix.

Aaron

[Igal @ getRailo.org]

the Windows dll doesn't ship with Railo.

you can get it at http://danadler.com/jacob/ and put it somewhere on your Windows path


Igal

[Igal @ getRailo.org]

apparently the dll does ship with Railo but it seems like something is preventing it from working properly.

can you open a ticket in the JIRA for this please?
https://issues.jboss.org/browse/RAILO


Igal

[Igal Sapir]

This should be fixed in the next update.
https://issues.jboss.org/browse/RAILO-2191

Any chance that update is tonight? :-)

I either need to refactor some code or roll back to 3.3

Doh!

Aaron

[Igal @ getRailo.org]

all that the update is doing is save the dll to the right folder.

you can do that manually right now.  extract the correct dll for your OS bit-size from the attached zip and save it to
{railo-server}\context\bin

you can find the location of the railo-server from the main page in the server administrator.

then restart Railo and test.

HTH,


Igal

[Aaron Davis]

Above and beyond man! Ill get that done when I get the kids to bed and can focus.

Thanks!

Aaron

<jacob-dll.zip>

[Igal @ getRailo.org]

you're welcome :)

please let us know if it worked,


Igal

[Aaron Davis]

I couldnt get this to work. I ended up giving up and refactoring the app at hand. Needed to be done anyway, but just wasnt planning to stay up all night doing it.

Thanks again for your efforts.

Aaron

[Igal]

ok, sorry it didn't work for you.

I don't have a test case so I wasn't able to ensure that the suggested fix works.

the only other thing I can think of is that the dll should be renamed to jacob.dll but I'm not sure if that would make a difference.

Igal

[Aaron Davis]

No worries. I think that there are likely other factors in play. it was the first railo/windows setup we did a while back and I imagine there could be something wrong at that level.

Aaron

[George]

I did not rename the file at all. I left the original name (jacob-1.16.1-x86.dll) and everything works fine.
