Some months ago when installing\/removing\/upgrading several Documentum components, we ended up facing a strange issue (yes I know, another one!). We were able to see these specific errors during the installation or removal of a Docbase, during the installation of a patch for the Content Server, the installation of the Thumbnail Server, aso… The errors we faced change for different installers but in the end, all of these errors were linked to the same issue. The only error that wasn’t completely useless was the one faced during the installation of a new docbase: “Content is not allowed in trailing section”. Yes I know this might not be really meaningful for everybody but this kind of error usually appears when an XML file isn’t formatted properly: some content isn’t allowed at this location in the file…<\/p>\n

 <\/p>\n

The strange thing is that these installers were working fine a few days before so what changed in the meantime exactly? After some research and analysis, I finally found the guilty! One thing that has been added in these few days was D2 which has been installed a few hours before the first error. Now what can be the link between D2 and these errors when running some installers? The first thing to do when there is an issue with D2 on the Content Server is to check the Java Method Server. The first time I saw this error, it was during the installation of a new docbase. As said before, I checked the logs of the Java Method Server and I found the following WARNING which confirmed what I suspected:<\/p>\n

So the error “Content is not allowed in trailing section” comes from the JMS which isn’t able to properly read the first character of the line 40 coming from an XML file “deployment descriptor”. So which file is that? That’s where the fun begin! There are several deployment descriptors in JBoss like web.xml, jboss-app.xml, jboss-deployment-structure.xml, jboss-web.xml, aso…<\/p>\n

The D2 installer is updating some configuration files like the server.ini. This is a text file, pretty simple to update and indeed the file is properly formatted\u00a0so no issue on this side. Except this file, the D2 installer is mainly updating XML files like the following ones:<\/div>\n
    \n
  • $DOCUMENTUM_SHARED\/jboss7.1.1\/server\/DctmServer_MethodServer\/deployments\/ServerApps.ear\/META-INF\/jboss-deployment-structure.xml<\/li>\n
  • $DOCUMENTUM_SHARED\/jboss7.1.1\/server\/DctmServer_MethodServer\/deployments\/ServerApps.ear\/DmMethods.war\/WEB-INF\/web.xml<\/li>\n
  • $DOCUMENTUM_SHARED\/jboss7.1.1\/server\/DctmServer_MethodServer\/deployments\/bpm.ear\/META-INF\/jboss-deployment-structure.xml<\/li>\n
  • $DOCUMENTUM_SHARED\/jboss7.1.1\/modules\/emc\/d2\/lockbox\/main\/module.xml<\/li>\n
  • aso…<\/li>\n<\/ul>\n
     <\/p>\n
    At this point, it was pretty simple to figure out the issue: I just checked all these files until I found the wrongly updated\/corrupted XML file. And the winner was… the file web.xml for the DmMethods inside the ServerApps. The D2 installer usually update\/read this file but in the process of doing so, it actually does also corrupt it… It is not a big corruption but it is still boring since it will prevent some installers from working properly and it will display the error shown above in the Java Method Server. Basically whenever you have some parsing errors, I would suggest you to take a look at the files web.xml across the JMS. The D2 Installer in our case added at the end of this file the word “ap”. As you know, an XML file should be properly formatted to be readable and “ap” isn’t a correct XML ending tag:<\/p>\n

     <\/p>\n
    So to correct this issue, you just have to remove the word “ap” from the end of this file, restart the JMS and finally restart any installer and the issue should be gone. That’s pretty simple but still annoying that installers provided by EMC can cause such trouble on their own products.<\/div>\n
     <\/p>\n
    The errors mentioned above are related to these XML files being wrongly updated by the D2 installer but that’s actually not the only installer that is often wrongly updating XML files. As far as I remember, the BPM installer and Thumbnail Server installer can also produce the exact same\u00a0issue and the reason behind that is probably that the XML files of the Java Method Server on Linux Boxes have a wrong FileFormat… We faced this issue with all versions that we installed so far on our different environments: CS 7.2 P02, P05, P16… Each and every time we install a new Documentum Content Server, all XML files of the JMS are all using the DOS FileFormat and this prevents the D2\/Thumbnail\/BPM installers to do their job.<\/p>\n
     <\/p>\n
    As a sub-note, I have also seen some issues with the file “jboss-deployment-structure.xml”. Just like the “web.xml” above, this one is also present for all applications deployed under the Java Method Server. Some installers will try to update this file (including D2, in order to configure the Lockbox in it) but again the same issue is happening, mostly because of the wrong FileFormat: I have already seen the whole content of this file just being removed by a Documentum installer… So before doing anything, I would suggest you to take a backup of the JMS as soon as it is installed and running and before installing all additional components like D2, bpm, Thumbnail Server, aso… On Linux, it is pretty easy to see and change the FileFormat of a file. Just open it using “vi” for example and then write “:set ff?”. This will display the current FileFormat and you can then change it using: “:set ff=unix”, if needed.<\/p>\n
     <\/p>\n
    I don’t remember seeing such kind of behavior before the CS 7.2 so maybe it is just linked to this specific version… If you already have seen such thing for a previous version, don’t hesitate to share!<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
