Getting WriteBeyondContentLengthException #6

Open johnsmitherpn5 opened 9 years ago

johnsmitherpn5 commented 9 years ago

Hi,

We have an internal Spring framework mvc web application. Which is running on WebSphere 8.5.

I am trying to setup stagemonitor to see the "In Browser Widget". Followed your wiki "Set up stagemonitor with your own Application".

But getting WriteBeyondContentLengthException when I try to access the login page itself. Please see the console log below...

Please let me know if I need to use any specific settings....Thanks.

@johnsmitherpn5: I think i know the cause of this issue.

@felixbarny: The reason is probably that the Content-Length HTTP-Header is not recalculated after injecting the stagemonitor html snippet. I've created an issue in the corresponding project: https://github.com/stagemonitor/stagemonitor/issues/74

I'll have a further look at this on sunday.

johnsmitherpn5 commented 9 years ago

@trampi : Thank you for the quick response. Will look forward for the fix.

trampi commented 9 years ago

@johnsmitherpn5: sorry for the late answer but i haven't found time on sunday or today. However, tomorrow should a pull request be ready.

felixbarny commented 9 years ago

@johnsmitherpn5 could you try out the fix? This is how to install the latest version into your local maven repository (~/.m2/repository)

git clone git@github.com:trampi/stagemonitor.git
cd stagemonitor
git checkout recalculate-content-length-header

Then build the project as described here: https://github.com/stagemonitor/stagemonitor#build-locally

If you're using maven, all you have to do is to update the version in pom.xml to 0.15.0-SNAPSHOT.

johnsmitherpn5 commented 9 years ago

@felixbarny : Sorry for the delay. Completely tied up in meetings. I am not able to install the fix. We are using maven but when I update the version in pom.xml to 0.15.0-SNAPSHOT getting maven dependency error. I tried git clone also but getting below error...

git clone git@github.com:trampi/stagemonitor.git

I could reproduce the mentioned WriteBeyondContentLengthException. I am working on a solution.

trampi commented 9 years ago

Further investigations showed that this exception happens in spring petclinic even without stagemonitor. The stagemonitor part however seems to work even with that exception. Unfortunately i can not find any information regarding the WriteBeyondContentLengthException in IBM WebSphere.

One last idea: Remove all calls to setContentLength in your application. It is not required. It is just nice to know in large file downloads to indicate the progress and to display the complete file size.

johnsmitherpn5 commented 9 years ago

@trampi : I am able to run petclinic example with stagemonitor on WebSphere. I am getting this issue in our application (spring based web application) and we don't have any setContentLength calls. I found something related to this in the below link. http://www-01.ibm.com/support/docview.wss?uid=swg1PI12194

But we are using latest version WebSphere than what they mentioned in the link. Below is the link to download the WebSphere Liberty Profile which is free for development and we are using same.

https://developer.ibm.com/wasdev/downloads/liberty-profile-using-non-eclipse-environments/

Also I am not able to download 0.15.0-SNAPSHOT using maven which @felixbarny mentioned.

felixbarny commented 9 years ago

I have finally found some time to look at this. The petclinic example runs fine for me on websphere. Do you have any example application that I can use to reproduce your problem? I have just released 0.15.2 in which I set the Content-Length header to -1 if it has already been set and if the widget is injected. That may fix your problem. Would you try out again?

janakarajp commented 8 years ago

did any one used / tested the option as mention the above post to fix issue, I am not sure which file we need specify " set the Content-Length header to -1" , Please do share the feedback.

felixbarny commented 8 years ago

You don't have to do this manually. Do you encounter simmilar problems?

janakarajp commented 8 years ago

Hi,

Yes, I do have slimier issue
