Doesn't provide correct completion suggestion for web.xml

[gayanper]

Given the following web.xml file with the content

<web-app 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xmlns="http://java.sun.com/xml/ns/javaee" 
  xmlns:web="http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" 
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" 
  version="4.0">
  
</web-app>

I don't get the full set of element completions for web-app schema with lemminx editor, even though the correct completions are shown in old Web Tools xml editor in Eclipse

[fbricon]

You have the namespace wrong. Try :

<?xml version="1.0" encoding="UTF-8"?>
<web-app 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
    xmlns:web="http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" 
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" 
    version="4.0">

</web-app> 

I noticed a bug in lemminx when, after an empty file has been opened, if you copy the content above, only http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd will be downloaded and cached locally (under ~/.lemminx/cache/...). Once lemminx restarts (after restarting the IDE), then all included XSDs will be downloaded, completion/validation can then work as expected.

[gayanper]

Yes it worked after restarting IDE with the correct definition. Should we keep this issue to fix the mentioned inconsistency until restart ?

[gayanper]

Ok seems the suggestion didn't worked. I tried a code snippet from oracle documentation as well, which didn't work with lemminx even after restart.

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
   version="2.4">
</web-app>

But completions work fine with old xml editor in eclipse.

[fbricon]

Indeed, it fails with 2.4. However web 2.5 works

<?xml version="1.0" encoding="UTF-8"?>
<web-app 
version="2.5" 
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
</web-app>

I don't know what's really happening, but my guess is the parser fails to load the 2.4 xsd, as, when you open it, there's a ton of errors bubbling up from included XSDs (There are '73' errors in 'http://www.ibm.com/webservices/xsd/j2ee_web_services_client_1_1.xsd'.), like:

s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'. Saw '"translation": {'.
s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'. Saw '"attribute9": "en-US",'.

Opening the 2.5 xsd shows some errors but no s4s-elt-characters

Anyays, @angelozerr should know better.

[fbricon]

well http://www.ibm.com/webservices/xsd/j2ee_web_services_client_1_1.xsd returns an HTML page, that's what is cached locally and probably messes everything

[fbricon]

@deboer-tim reminds you of https://bugs.eclipse.org/bugs/show_bug.cgi?id=152355 ain't it? ;-)

[fbricon]

As a workaround, you can copy the contents of https://www.jboss.org/j2ee/schema/j2ee_web_services_client_1_1.xsd into your ~/.lemminx/cache/http/www.ibm.com/webservices/xsd/j2ee_web_services_client_1_1.xsd

@angelozerr told you we needed to embed a cached catalog ;-)

[deboer-tim]

@deboer-tim reminds you of https://bugs.eclipse.org/bugs/show_bug.cgi?id=152355 ain't it? ;-)

That brings back memories! Let's hope we don't have a similar bug in another IDE 15 years from now. 😂

[angelozerr]

I have tried to understand the problem of this issue and I think there are 2 problems (one from LemMinX and one from LSP4E but I'm not sure).

The first thing that you must know is that WTP uses the WTP XML catalog for http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd (local file in this case). So there are no download. WWD which integrates LemMinx provides the capability to generate a XML catalog from WTP:

You can a system-catalog.xml which is generated from the WTP XML catalog:

In this system catalog it defines the http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd with uri:

<uri name="http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" uri="file:///C:/Users/azerr/eclipse-workspace2/.metadata/.plugins/org.eclipse.pde.core/Eclipse%20Application/org.eclipse.osgi/538/0/.cp/dtdsAndSchemas/web-app_4_0.xsd"/>

After debugging LemMinx it seems that the XML catalog resolver of LemMinx cannot takes care of this uri. I will create a PR for that which works good on vscode-xml by using the WTP XML editor catalog. When I use WTP XML editor catalog in vscode-xml , there are no download in .lemminx.

But in Eclipse IDE, the completion doesn't appear even with this fix although I can see the JSON response in the Eclipse console:

Perhaps there are some characters which crashes the LSP4E ? //cc @mickaelistria

For using WTP XML catalog correctly with completion (in other words no XSD should be downloaded in .lemminx cache folder), see Resolve uri as system with XML catalog #1199

Ok I find the problem, it's a LSP4J problem, I created the issue eclipse-lsp4j/lsp4j#616

By waiting a fix I will replace special character “ with "

UPDATE : it is a problem by using a Launch, so please ignore my comments.

[angelozerr]

My PR #1200 should fix all problems when it will be integrated in WWD:

• completion should work like WTP XML editor
• validation should work like WTP XML editor

It is because my PR can use now all XSD / DTD declared in the WTP XML catalog and it should never download those web-app XSD in .lemminx cache.

BUT when you have not this catalog, the issues will exist again:

• you need to restart the vscode to download the full XSD (why? I don't know). I created the issue at Need to restart the IDE / Editor to download the full XSD #1207
• you will have again a problem with http://www.ibm.com/webservices/xsd/j2ee_web_services_client_1_1.xsd like explain in Doesn't provide correct completion suggestion for web.xml  #1196 (comment) but for that we cannot do nothing (just provide a default XML catalog).

[angelozerr]

I close this issue because the issue should be fixed (completion should work now) when lemminx uses the WTP XML catalog. This issue should be fixed with #1199.

When XML catalog is not used there are a problem with some download (it is for some web-app XSD version). I created the issue for taht at #1207
